Section 1 Seats and Restraint Systems Here you’ll find information about the seats in your vehicle and how to use your safety belts properly. You can also learn about some things you should not do with air bags and safety belts.
Seats and Seat Controls This section tells you about the seats -- how to adjust them, and fold them up and down. It also tells you about reclining front seatbacks and head restraints. Manual Front Seat CAUTION: You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you don’t want to. Adjust the driver’s seat only when the vehicle is not moving.
Manual Lumbar Control (If Equipped) Power Seat(s) (If Equipped) If your vehicle has a lumbar adjustment, the knob is located on the outboard side of the seat cushion. To increase or decrease support, turn the knob toward the front or rear of the vehicle. Operating effort can be reduced if you lean forward slightly while turning the knob. If your vehicle has a power seat, you can adjust it with these controls located on the outboard sides of the seats.
D Move the seat forward or rearward by moving the Power Lumbar Control (If Equipped) whole horizontal control forward or rearward. D Raise or lower the rear of the seat cushion by raising or lowering the rear edge of the horizontal control. D Moving the whole horizontal control up or down If your vehicle has this feature, the four-way control is located on the outboard side of the seat. raises or lowers the entire seat cushion.
Memory Seat (If Equipped) If your vehicle has this feature, the buttons used to program and recall the driver’s seat and recliner position are located on the driver’s door trim panel. It does not store the lumbar or back support positions. To program the memory seat, do the following: 1. Adjust the driver’s seat to the desired position. 2. Then press the SET button and, within five seconds, press one of the two numbered buttons on the memory control.
Reclining Seatbacks To adjust the front seatback, lift the manual lever located on the outboard side of the seat. Release the lever to lock the seatback where you want it. Lift the lever again without pushing on the seatback and the seatback will go to an upright position. If your vehicle has power seats with a power recliner, see “Power Seats” in the Index for further information on how to operate the reclining seatback feature. 1-6 But don’t have a seatback reclined if your vehicle is moving.
Head Restraints CAUTION: Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can’t do their job when you’re reclined like this. The shoulder belt can’t do its job. In a crash, you could go into it, receiving neck or other injuries. The lap belt can’t do its job either. In a crash the belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones. This could cause serious internal injuries.
On some models, the head restraints tilt forward and rearward also. The seatbacks fold forward to let you access the rear of the cab. The rear seat head restraints in your vehicle may be adjustable. They work the same as the front seat head restraints, except they do not tilt forward or rearward. To fold a front seatback forward, lift the lever at the base of the seat to release the seatback. Seatback Latches CAUTION: If the seatback isn’t locked, it could move forward in a sudden stop or crash.
Rear Seat (Extended Cab) Folding the Rear Seat The extended cab’s rear seat can be folded up to provide more cargo space. To fold the seat do the following: 1. Pull forward on the release strap located under the rear seat cushion. The extended cab’s rear seat can also be folded open for more seating space. To use the seat do the following: 1. Push rearward on the seat cushion while pulling up on the release strap under the seat cushion. Pull the seat cushion downward until it latches. 2.
To fold the rear seat, do the following: 1. Pull up on the strap loop at the rear of the seat cushion. Then, pull the seat cushion up and fold it forward. 3. Pull forward on the seatback and up on the seat cushion to make sure the seat is securely in place. Check to see that the buckles on the driver’s side seatback are accessible to the outboard and center occupant and are not under the seat cushions. Safety Belts: They’re for Everyone This part of the manual tells you how to use safety belts properly.
You never know if you’ll be in a crash. If you do have a crash, you don’t know if it will be a bad one. CAUTION: It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, people riding in these areas are more likely to be seriously injured or killed. Do not allow people to ride in any area of your vehicle that is not equipped with seats and safety belts. Be sure everyone in your vehicle is in a seat and using a safety belt properly.
Take the simplest vehicle. Suppose it’s just a seat on wheels. 1-12 Put someone on it.
Get it up to speed. Then stop the vehicle. The rider doesn’t stop. The person keeps going until stopped by something. In a real vehicle, it could be the windshield ...
or the instrument panel ... or the safety belts! With safety belts, you slow down as the vehicle does. You get more time to stop. You stop over more distance, and your strongest bones take the forces. That’s why safety belts make such good sense.
Here Are Questions Many People Ask About Safety Belts -- and the Answers Q: Won’t I be trapped in the vehicle after an accident if I’m wearing a safety belt? A: You could be -- whether you’re wearing a safety belt or not. But you can unbuckle a safety belt, even if you’re upside down. And your chance of being conscious during and after an accident, so you can unbuckle and get out, is much greater if you are belted.
How to Wear Safety Belts Properly Adults This part is only for people of adult size. Be aware that there are special things to know about safety belts and children. And there are different rules for smaller children and babies. If a child will be riding in your vehicle, see the part of this manual called “Children.” Follow those rules for everyone’s protection. First, you’ll want to know which restraint systems your vehicle has. We’ll start with the driver position.
4. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. If the belt isn’t long enough, see “Safety Belt Extender” at the end of this section. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones.
Q: What’s wrong with this? CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit against your body. A: The shoulder belt is too loose. It won’t give nearly as much protection this way.
Q: What’s wrong with this? CAUTION: You can be seriously injured if your belt is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen. The belt forces would be there, not at the pelvic bones. This could cause serious internal injuries. Always buckle your belt into the buckle nearest you. A: The belt is buckled in the wrong place.
Q: What’s wrong with this? CAUTION: You can be seriously injured if your belt goes over an armrest like this. The belt would be much too high. In a crash, you can slide under the belt. The belt force would then be applied at the abdomen, not at the pelvic bones, and that could cause serious or fatal injuries. Be sure the belt goes under the armrests. A: The belt is over an armrest.
Q: What’s wrong with this? CAUTION: You can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would move too far forward, which would increase the chance of head and neck injury. Also, the belt would apply too much force to the ribs, which aren’t as strong as shoulder bones. You could also severely injure internal organs like your liver or spleen. A: The shoulder belt is worn under the arm. It should be worn over the shoulder at all times.
Q: What’s wrong with this? CAUTION: You can be seriously injured by a twisted belt. In a crash, you wouldn’t have the full width of the belt to spread impact forces. If a belt is twisted, make it straight so it can work properly, or ask your dealer to fix it. A: The belt is twisted across the body.
Safety Belt Use During Pregnancy Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they don’t wear safety belts. To unlatch the belt, just push the button on the buckle. The belt should go back out of the way. Before you close the door, be sure the belt is out of the way. If you slam the door on it, you can damage both the belt and your vehicle.
The best way to protect the fetus is to protect the mother. When a safety belt is worn properly, it’s more likely that the fetus won’t be hurt in a crash. For pregnant women, as for anyone, the key to making safety belts effective is wearing them properly. Right Front Passenger Position To learn how to wear the right front passenger’s safety belt properly, see “Driver Position” earlier in this section.
CAUTION: Air bags inflate with great force, faster than the blink of an eye. If you’re too close to an inflating air bag, as you would be if you were leaning forward, it could seriously injure you. Safety belts help keep you in position before and during a crash. Always wear your safety belt, even with air bags. The driver should sit as far back as possible while still maintaining control of the vehicle.
There is an air bag readiness light on the instrument panel, which shows the air bag symbol. How the Air Bag System Works The system checks the air bag electrical system for malfunctions. The light tells you if there is an electrical problem. See “Air Bag Readiness Light” in the Index for more information. Where are the air bags? The driver’s air bag is in the middle of the steering wheel.
CAUTION: If something is between an occupant and an air bag, the bag might not inflate properly or it might force the object into that person causing severe injury or even death. The path of an inflating air bag must be kept clear. Don’t put anything between an occupant and an air bag, and don’t attach or put anything on the steering wheel hub or on or near any other air bag covering. The right front passenger’s air bag is in the instrument panel on the passenger’s side.
When should an air bag inflate? What makes an air bag inflate? An air bag is designed to inflate in a moderate to severe frontal or near-frontal crash. The air bag will inflate only if the impact speed is above the system’s designed “threshold level.” If your vehicle goes straight into a wall that doesn’t move or deform, the threshold level is about 9 to 16 mph (14 to 26 km/h). The threshold level can vary, however, with specific vehicle design, so that it can be somewhat above or below this range.
What will you see after an air bag inflates? After an air bag inflates, it quickly deflates, so quickly that some people may not even realize the air bag inflated. Some components of the air bag module -- the steering wheel hub for the driver’s air bag, or the instrument panel for the right front passenger’s bag -- will be hot for a short time. The parts of the bag that come into contact with you may be warm, but not too hot to touch.
D Let only qualified technicians work on your air bag system. Improper service can mean that your air bag system won’t work properly. See your dealer for service. NOTICE: If you damage the covering for the driver’s or the right front passenger’s air bag, the bag may not work properly. You may have to replace the air bag module in the steering wheel or both the air bag module and the instrument panel for the right front passenger’s air bag. Do not open or break the air bag coverings.
This switch should only be turned to AIR BAG OFF if the person in the right front passenger’s position is a member of a passenger risk group identified by the national government as follows: Infant.
Medical Condition. A passenger has a medical condition which, according to his or her physician: D causes the passenger air bag to pose a special risk for the passenger; and D makes the potential harm from the passenger air bag in a crash greater than the potential harm from turning off the air bag and allowing the passenger, even if belted, to hit the dashboard or windshield in a crash.
CAUTION: If the air bag readiness light ever comes on when you have turned off the air bag, it means that something may be wrong with the air bag system. The right front passenger’s air bag could inflate even though the switch is off.
Servicing Your Air Bag-Equipped Vehicle Air bags affect how your vehicle should be serviced. There are parts of the air bag system in several places around your vehicle. You don’t want the system to inflate while someone is working on your vehicle. Your dealer and the service manual have information about servicing your vehicle and the air bag system. To purchase a service manual, see “Service and Owner Publications” in the Index.
Q: What if I add a snow plow? Will it keep the air bags from working properly? A: We’ve designed our air bag systems to work properly under a wide range of conditions, including snow plowing with vehicles equipped with the optional Snow Plow Prep Package (RPO VYU). But don’t change or defeat the snow plow’s “tripping mechanism.” If you do, it can damage your snow plow and your vehicle, and it may cause an air bag inflation.
Rear Seat Passengers It’s very important for rear seat passengers to buckle up! Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts. Rear passengers who aren’t safety belted can be thrown out of the vehicle in a crash. And they can strike others in the vehicle who are wearing safety belts.
Lap-Shoulder Belt (Extended Cab and Crew Cab) The positions next to the windows have lap-shoulder belts. Here’s how to wear one properly. 2. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. When the shoulder belt is pulled out all the way, it will lock. If it does, let it go back all the way and start again. If the belt is not long enough, see “Safety Belt Extender” at the end of this section.
3. To make the lap part tight, pull down on the buckle end of the belt as you pull up on the shoulder part. 1-38 The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones. And you’d be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen. This could cause serious or even fatal injuries. The shoulder belt should go over the shoulder and across the chest.
The safety belt locks if there’s a sudden stop or a crash. The safety belt also locks if you pull the belt very quickly out of the retractor. CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit against your body. To unlatch the belt, just push the button on the buckle.
Rear Safety Belt Comfort Guides for Children and Small Adults If your vehicle has a rear seat, your vehicle has shoulder belt comfort guides. This feature will provide added safety belt comfort for older children who have outgrown booster seats and for small adults. When installed on a shoulder belt, the comfort guide better positions the belt away from the neck and head. There is one guide for each outside passenger in the rear seat.
2. Place the guide over the belt and insert the two edges of the belt into the slots of the guide. 3. Be sure that the belt is not twisted and it lies flat. The guide must be on top of the belt.
Children Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle.
CAUTION: (Continued) For example, in a crash at only 25 mph (40 km/h), a 12-lb. (5.5 kg) baby will suddenly become a 240-lb. (110 kg) force on a person’s arms. A baby should be secured in an appropriate restraint. CAUTION: People should never hold a baby in their arms while riding in a vehicle. A baby doesn’t weigh much -- until a crash. During a crash a baby will become so heavy it is not possible to hold it.
Q: What are the different types of add-on child restraints? A: Add-on child restraints, which are purchased by the vehicle’s owner, are available in four basic types. Selection of a particular restraint should take into consideration not only the child’s weight, height and age but also whether or not the restraint will be compatible with the motor vehicle in which it will be used. CAUTION: Children who are up against, or very close to, any air bag when it inflates can be seriously injured or killed.
CAUTION: Newborn infants need complete support, including support for the head and neck. This is necessary because a newborn infant’s neck is weak and its head weighs so much compared with the rest of its body. In a crash, an infant in a rear-facing seat settles into the restraint, so the crash forces can be distributed across the strongest part of an infant’s body, the back and shoulders. Infants always should be secured in appropriate infant restraints.
Restraint Systems for Children An infant car bed (A), a special bed made for use in a motor vehicle, is an infant restraint system designed to restrain or position a child on a continuous flat surface. Make sure that the infant’s head rests toward the center of the vehicle. 1-46 A rear-facing infant seat (B) provides restraint with the seating surface against the back of the infant. The harness system holds the infant in place and, in a crash, acts to keep the infant positioned in the restraint.
A forward-facing child seat (C-E) provides restraint for the child’s body with the harness and also sometimes with surfaces such as T-shaped or shelf-like shields. A booster seat (F-G) is a child restraint designed to improve the fit of the vehicle’s safety belt system. Some booster seats have a shoulder belt positioner, and some high-back booster seats have a five-point harness. A booster seat can also help a child to see out the window.
Q: A: How do child restraints work? A child restraint system is any device designed for use in a motor vehicle to restrain, seat, or position children. A built-in child restraint system is a permanent part of the motor vehicle. An add-on child restraint system is a portable one, which is purchased by the vehicle’s owner. For many years, add-on child restraints have used the adult belt system in the vehicle. To help reduce the chance of injury, the child also has to be secured within the restraint.
Where to Put the Restraint (Regular Cab Pickup) Where to Put the Restraint (Extended Cab Pickup) The child restraint must be secured properly in the right front passenger seat. If you want to secure a rear-facing child restraint in the right front passenger’s seat, turn off the passenger’s air bag. See “Air Bag Off Switch” and “Securing a Child Restraint in the Right Front Seat Position” in the Index for more on this, including important safety information.
CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating air bag. Be sure to turn off the air bag before using a rear-facing child restraint in the right front seat position. Wherever you install it, be sure to secure the child restraint properly.
Top Strap CAUTION: A child riding in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating air bag. Always secure a rear-facing child restraint in the rear seat. You may secure a forward-facing child restraint in the right front seat, but before you do, always move the front passenger seat as far back as it will go.
Anchor the top strap to one of the following anchor points. Be sure to use an anchor point located on the same side of the vehicle as the seating position where the child restraint will be placed. Raise the head restraint and route the top strap under it. Once you have the top strap anchored, you’ll be ready to secure the child restraint itself. Tighten the top strap when and as the child restraint manufacturer’s instructions say.
Right Front Passenger Position Top Strap Anchor (All Models) You’ll find the top strap anchor for the right front passenger seat behind the seat, near the floor. If your vehicle is a regular cab model, there is also a top strap anchor for the right front passenger position located on the back panel of your vehicle, behind the right front passenger seat. In order to get to the anchor, you’ll have to remove the trim plug covering it.
Rear Seat Top Strap Anchors (Extended Cab Models) If your vehicle is an extended cab model, you’ll find the top strap anchors for the rear seating positions near the top of the seatback. In addition to the top strap anchors, each seating position has a fabric loop at the top of the seatback that you’ll use to route a top strap through.
Rear Seat Top Strap Anchors (Crew Cab Models) When using a child restraint with a top strap in the center rear position, route the top strap through the fabric loop on the seatback. Then, raise the head restraint and attach the top strap to the anchor point located at the closest outboard position. Once you have the top strap anchored, you’ll be ready to secure the child restrain itself. Tighten the top strap when and as the child restraint manufacturer’s instructions say.
Lower Anchorages and Top Tethers for Children (LATCH System) (If Equipped) Your vehicle may have the LATCH system. If it does, you’ll find anchors (A) in the seat, where the seatback meets the seat cushion. For front passenger seat positions, there is an anchor behind and to the bottom of the seat to secure the top strap. For rear center seat positions, there is an anchor near the driver’s side rear seat head restraint.
In order to use the system, you need either a forward-facing child restraint that has attaching points (B) at its base and a top tether anchor (C), or a rear-facing child restraint that has attaching points (B), as shown here. With this system, use the LATCH system instead of the vehicle’s safety belts to secure a child restraint.
CAUTION: If a LATCH-type child restraint isn’t attached to its anchorage points, the restraint won’t be able to protect a child sitting there. In a crash, the child could be seriously injured or killed. Make sure that a LATCH-type child restraint is properly installed using the anchorage points, or use the vehicle’s safety belts to secure the restraint.
Securing a Child Restraint in a Rear Outside Seat Position (Extended Cab and Crew Cab) There is limited space in the rear seating area of an extended cab model. If you want to secure a child restraint in a rear outside seating position, be sure to study the instructions that came with your child restraint to see if there is enough room to secure your seat properly. You’ll be using the lap-shoulder belt. See the earlier part about the top strap if the child restraint has one.
3. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 1-60 4. Pull the rest of the shoulder belt all the way out of the retractor to set the lock.
5. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. If you’re using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt. 6. Push and pull the child restraint in different directions to be sure it is secure. To remove the child restraint, just unbuckle the vehicle’s safety belt and let it go back all the way.
Securing a Child Restraint in the Center Front Seat Position Don’t use child restraints in this position. The restraints won’t work properly. 1-62 Securing a Child Restraint in the Center Rear Seat Position (Extended Cab and Crew Cab) If you have an extended cab or a Crew Cab pickup, you can secure a child restraint in the center rear seat position.
There is limited space in the rear seating area of an extended cab model. If you want to secure a child restraint in a rear seating position of an extended cab model, especially in the rear center position, be sure to study the instructions that came with your child restraint to see if there is enough room to secure your seat properly. You’ll be using the lap belt. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say.
3. Run the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how. 4. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 5. To tighten the belt, pull its free end while you push down on the child restraint. If you’re using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt. 6.
Securing a Child Restraint in the Right Front Seat Position If your child restraint is equipped with the LATCH system, see “Lower Anchorages and Top Tethers for Children (LATCH)” in the Index. Crew Cab Models: Your vehicle has a right front passenger air bag. Never put a rear-facing child restraint in this seat. Here’s why: Regular Cab and Extended Cab Models: Your vehicle has a right front passenger air bag.
CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating air bag. Be sure to turn off the air bag before using a rear-facing child restraint in the right front seat position. If a forward-facing child restraint is suitable for your child, always move the passenger seat as far back as it will go.
You’ll be using the lap-shoulder belt. See the earlier part about the top strap if the child restraint has one. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say. 1. Your vehicle has a right front passenger’s air bag. If your vehicle is a regular cab or an extended cab and you are using a rear-facing child restraint in this seat, make sure the air bag is turned off. See “Air Bag Off Switch” in the Index.
5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 6. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. If you’re using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt. 7. Push and pull the child restraint in different directions to be sure it is secure.
To remove the child restraint, just unbuckle the vehicle’s safety belt and let it go back all the way. The safety belt will move freely again and be ready to work for an adult or larger child passenger. If you were using a rear-facing child restraint in a regular cab pickup or an extended cab pickup, turn on the right front passenger’s air bag when you remove the rear-facing child restraint from the vehicle unless the person who will be sitting there is a member of a passenger air bag risk group.
Older Children Q: A: What is the proper way to wear safety belts? If possible, an older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips, just touching the top of the thighs. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash.
CAUTION: Never do this. Here two children are wearing the same belt. The belt can’t properly spread the impact forces. In a crash, the two children can be crushed together and seriously injured. A belt must be used by only one person at a time.
CAUTION: Never do this. Here a child is sitting in a seat that has a lap-shoulder belt, but the shoulder part is behind the child. If the child wears the belt in this way, in a crash the child might slide under the belt. The belt’s force would then be applied right on the child’s abdomen. That could cause serious or fatal injuries. Wherever the child sits, the lap portion of the belt should be worn low and snug on the hips, just touching the child’s thighs.
Safety Belt Extender If the vehicle’s safety belt will fasten around you, you should use it. But if a safety belt isn’t long enough to fasten, your dealer will order you an extender. It’s free. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you. The extender will be just for you, and just for the seat in your vehicle that you choose. Don’t let someone else use it, and use it only for the seat it is made to fit.
✍ 1-74 NOTES
Section 2 Features and Controls Here you can learn about the many standard and optional features on your vehicle, and information on starting, shifting and braking. Also explained are the instrument panel and the warning systems that tell you if everything is working properly -- and what to do if you have a problem.
Windows CAUTION: Leaving children in a vehicle with the windows closed is dangerous. A child can be overcome by the extreme heat and can suffer permanent injuries or even death from heat stroke. Never leave a child alone in a vehicle, especially with the windows closed in warm or hot weather. Manual Windows Turn the hand crank on each door to manually raise or lower the manual windows.
Power Windows (If Equipped) The driver’s door has a switch for the passenger window as well. Your power windows will work when the ignition has been turned to ACCESSORY or RUN or when Retained Accessory Power (RAP) is active. See “Retained Accessory Power” in the Index. Press the top or bottom of the switch with the power window symbol on it to lower or raise the window.
Lock-Out Switch If you have power windows on a Crew CabR, the driver’s door power window switch has a lockout feature. This feature prevents all windows from operating, except from the driver’s position, when the driver’s door button labeled WINDOW LOCK is engaged. When the button is not engaged, the rear power windows will operate. Swing-Out Windows (Extended Cab) To open a rear swing-out window, flip the latch open and swing the glass out.
Keys CAUTION: Leaving children in a vehicle with the ignition key is dangerous for many reasons. A child or others could be badly injured or even killed. They could operate the power windows or other controls or even make the vehicle move. Don’t leave the keys in a vehicle with children.
Your vehicle has one double-sided key for the ignition and all door locks. If you ever lose your keys, your dealer will be able to assist you with obtaining replacements. NOTICE: Your vehicle has a number of new features that can help prevent theft. But you can have a lot of trouble getting into your vehicle if you ever lock your key inside. You may even have to damage your vehicle to get in. So be sure you have an extra key.
Door Locks There are several ways to lock and unlock your vehicle. You can use the keyless entry system (if equipped). CAUTION: Unlocked doors can be dangerous. D Passengers -- especially children -- can easily open the doors and fall out of a moving vehicle. When a door is locked, the handle won’t open it. You increase the chance of being thrown out of the vehicle in a crash if the doors aren’t locked. So, wear safety belts properly and lock the doors whenever you drive.
Power Door Locks (If Equipped) If your vehicle has this power door lock switch, press the raised side of the switch, marked L, on either front door to lock all the doors at once. Press the recessed side of the switch marked U to unlock all the doors at once. If your vehicle has this power door lock switch, press the bottom of the switch on either front door to lock all the doors at once. Press the top of the switch to unlock all the doors at once.
Programmable Automatic Door Locks (If Equipped) To enter the program mode you need to do the following: If your vehicle has power door locks, it is equipped with a feature that enables you to program the door locks. 1. Beginning with the ignition in OFF. Pull back on the turn signal/multifunction lever all the way toward you until flash-to-pass is activated, and hold it while you perform the next step.
The following is a list of the available programming options: Lockout Prevention D All doors lock/Only the driver’s door unlocks: To protect you from locking your key in the vehicle, this feature stops the power door locks from locking when the key is in the ignition and a door is open. D All doors lock/All doors unlock: Press the lock side If the power lock switch is pressed when a door is open and the key is in the ignition, all of the doors will lock and then the driver’s door will unlock.
Child Security Locks (Crew Cabs) (If Equipped) With this feature, you can lock the rear side doors so that they cannot be opened from the inside by passengers. Your vehicle may have one of the two child security lock labels shown. This feature is located on the inside edge of the rear doors. Move the lever forward to engage the security feature. Move the lever rearward to return the door locks to normal operation.
Keyless Entry System (If Equipped) If your vehicle has this feature, you can lock and unlock your doors from about 3 feet (1 m) up to 100 feet (30 m) away using the remote keyless entry transmitter supplied with your vehicle. Your keyless entry system operates on a radio frequency subject to Federal Communications Commission (FCC) Rules and with Industry Canada. This device complies with Part 15 of the FCC Rules.

Pressing UNLOCK again within three seconds will cause the remaining doors to unlock. The parking lamps will flash and the interior lights will come on. When the panic button with the horn symbol on the keyless entry transmitter is pressed, the horn will sound and the headlamps and taillamps will flash for up to 30 seconds.
Battery Replacement Under normal use, the battery in your remote keyless entry transmitter should last about two years. To replace the battery in the keyless entry transmitter, do the following: You can tell the battery is weak if the transmitter won’t work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it’s probably time to change the battery. NOTICE: When replacing the battery, use care not to touch any of the circuitry.
Resynchronization Rear Doors Resynchronization may be necessary due to the security method used by this system. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal that has been sent previously. This prevents anyone from recording and playing back the signal from the transmitter. Your vehicle may be equipped with a rear access door(s) that allows easier access to the rear area of the extended cab.
To open a rear access door from the inside, the front door must be opened first. Then, use the handle located on the inside of the rear access door to open it. Tailgate You can open the tailgate by lifting up on its handle while pulling the tailgate toward you. To shut the tailgate, firmly push it upward until it latches. After you put the tailgate back up, pull it back towards you to be sure it latches securely. If your vehicle is a Crew Cab, you can open your doors from the inside or outside.
2. With the tailgate at a slight upward angle, pull back on the tailgate at the right edge and then move the tailgate to the right to release the left edge. Tailgate Removal The tailgate on your vehicle can be removed to allow for different loading situations. Although the tailgate can be removed without assistance, you may want someone to assist you with the removal to avoid possible damage to the vehicle. To remove the tailgate, do the following: 1.
Key in the Ignition Parking at Night If you leave your vehicle with the keys inside, it’s an easy target for joy riders or professional thieves -- so don’t do it. Park in a lighted spot, close all windows and lock your vehicle. Remember to keep your valuables out of sight. Put them in a storage area, or take them with you. When you park your vehicle and open the driver’s door, you’ll hear a chime reminding you to remove your key from the ignition and take it with you. Always do this.
Content Theft-Deterrent (If Equipped) Your vehicle may be equipped with a Content Theft-Deterrent alarm system. With this system, the SECURITY message will flash as you open the door if the ignition is off. If a door is opened without the key or the remote keyless entry transmitter, the alarm will go off. Your vehicle’s headlamps will flash and the horn will sound for about two minutes, then will turn off to save the battery power.
Testing the Alarm The alarm can be tested by following these steps: 1. From inside the vehicle, lower the driver’s window and open the driver’s door. 2. Activate the system by locking the doors with the power door lock switch while the door is open, or with the remote keyless entry transmitter. 3. Get out of the vehicle, close the door and wait for the SECURITY message to go out. 4. Then reach in through the window, unlock the door with the manual door lock and open the door. This should set off the alarm.
New Vehicle “Break-In” NOTICE: Your vehicle doesn’t need an elaborate “break-in.” But it will perform better in the long run if you follow these guidelines: D Keep your speed at 55 mph (88 km/h) or less for the first 500 miles (805 km). D Don’t drive at any one speed -- fast or slow -- for the first 500 miles (805 km). Don’t make full-throttle starts. D Avoid making hard stops for the first 200 miles (322 km) or so. During this time your new brake linings aren’t yet broken in.
B (LOCK): This position locks your ignition and transmission. It’s a theft-deterrent feature. You will only be able to remove your key when the ignition is turned to LOCK. CAUTION: On manual transmission vehicles, turning the key to LOCK will lock the steering column and result in a loss of ability to steer the vehicle. This could cause a collision. If you need to turn the engine off while the vehicle is moving, turn the key only to OFF. Don’t press the key release button while the vehicle is moving.
Key Release Button (Manual Transmission) The ignition key cannot be removed from the ignition of manual transmission vehicles unless the key release button is used. Retained Accessory Power (RAP) (If Equipped) Your vehicle may be equipped with a Retained Accessory Power (RAP) feature which will allow certain features on your vehicle to continue to work up to 20 minutes after the ignition key is turned to OFF.
Starting Your Engine Starting Your V8 Engine Automatic Transmission 1. With your foot off the accelerator pedal, turn the ignition key to START. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm. Move your shift lever to PARK (P) or NEUTRAL (N). Your engine won’t start in any other position -- that’s a safety feature. To restart when you’re already moving, use NEUTRAL (N) only. NOTICE: Don’t try to shift to PARK (P) if your vehicle is moving.
When starting your engine in very cold weather (below 0_F or -18_C), do this: 1. With your foot off the accelerator pedal, turn the ignition key to START and hold it there up to 15 seconds. When the engine starts, let go of the key. 2. If your engine still won’t start (or starts but then stops), it could be flooded with too much gasoline. Try pushing your accelerator pedal all the way to the floor and holding it there as you hold the key in START for about three seconds.
To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord. The cord is located on the driver’s side of the engine compartment, near the power steering fluid reservoir. 3. Plug it into a normal, grounded 110-volt AC outlet. CAUTION: Plugging the cord into an ungrounded outlet could cause an electrical shock. Also, the wrong kind of extension cord could overheat and cause a fire. You could be seriously injured.
Automatic Transmission Operation If your vehicle is equipped with an automatic transmission, it features an electronic shift position indicator within the instrument panel cluster. This display must be powered anytime the shift lever is capable of being moved out of PARK (P). This means that if your key is in OFF, rather than LOCK, there will be a small current drain on your battery which could discharge your battery over a period of time.
PARK (P): This position locks your rear wheels. It’s the best position to use when you start your engine because your vehicle can’t move easily. If your vehicle is equipped with the AllisonR Transmission, use park for stationary operation of the Power Takeoff (PTO) (if equipped). CAUTION: It is dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll. Don’t leave your vehicle when the engine is running unless you have to.
REVERSE (R): Use this gear to back up. If your vehicle is equipped with the Allison Transmission, the R may blink on the PRNDL if the shift inhibitor is active. NOTICE: Shifting to REVERSE (R) while your vehicle is moving forward could damage your transmission. Shift to REVERSE (R) only after your vehicle is stopped. If your vehicle is equipped with the Allison Transmission, do not idle in REVERSE (R) for more than five minutes. Extended idling in REVERSE (R) may cause transmission overheating and damage.
DRIVE (D): This position is for normal driving. If you need more power for passing, and you’re: D Going less than about 35 mph (55 km/h), push your accelerator pedal about halfway down. D Going about 35 mph (55 km/h) or more, push the accelerator all the way down. You’ll shift down to the next gear and have more power. DRIVE (D) can be used when towing a trailer, carrying a heavy load, driving on steep hills or for off-road driving.
FIRST (1): This position gives you even more power (but lower fuel economy) than SECOND (2). You can use it on very steep hills, or in deep snow or mud. If the selector lever is put in FIRST (1) while the vehicle is moving forward, the transmission won’t shift into first gear until the vehicle is going slowly enough.

Then, slowly let up on the clutch pedal as you press the accelerator pedal. Shift into FIRST (1) only when the vehicle is below 5 mph (8 km/h). If you try to shift down into FIRST (1) at excessive vehicle speeds, the shift lever will not move into FIRST (1) until vehicle speed is reduced.
FOURTH (4) and FIFTH (5): Shift into the higher forward gears the same way you do for THIRD (3). Slowly let up on the clutch pedal as you press the accelerator pedal. Five-Speed (VORTEC 4300 V6 and 4800 V8 Engines) To stop, let up on the accelerator pedal and press the brake pedal. Just before the vehicle stops, press the clutch pedal and the brake pedal, and shift to NEUTRAL. FIRST (1): Press the clutch pedal and shift into FIRST (1).
NEUTRAL: Use this position when you start or idle your engine. REVERSE (R): To back up, first press down the clutch pedal. Wait for the vehicle to stop moving and then, shift into REVERSE (R). Let up on the clutch pedal slowly while pressing the accelerator pedal. Six-Speed (VORTEC 8100 V8 and DURAMAX 6600 V8 Engines) t Here’s how to operate your transmission. NOTICE: Shift to REVERSE (R) only after your vehicle is stopped.
During the first 500 miles (805 km) of vehicle use, start the vehicle moving in FIRST (1) gear. This allows the clutch components to wear-in properly. THIRD (3): Press the clutch pedal and upshift into THIRD (3). Then, slowly let up on the clutch pedal as you press the accelerator pedal. FIRST (1): With the vehicle at a stop, release the brake, press the clutch pedal and shift into FIRST (1). Then, slowly let up on the clutch pedal as you press the accelerator pedal.
Shift Speeds CAUTION: If you skip a gear when you downshift, you could lose control of your vehicle. You could injure yourself or others. Don’t shift down more than one gear at a time when you downshift. Do not allow the engine rpm to overspeed and enter the tachometer red lines. Engine overspeed occurs when downshifting, or descending a grade, at too high a vehicle speed. When going down steep grades, always select a gear at least one position lower than you would use on climbing a grade.
Shift Light Parking Brake If you have a manual transmission, you may have a SHIFT light. This light will show you when to shift to the next higher gear for best fuel economy. To set the parking brake, hold the regular brake pedal down with your right foot. Push down the parking brake pedal with your left foot.

Instrument Panel Cluster United States Heavy Duty Automatic Transmission version shown. Canada, Light Duty Automatic and Manual Transmission Clusters similar.
Your instrument cluster is designed to let you know at a glance how your vehicle is running. You’ll know how fast you’re going, about how much fuel you have and many other things you’ll need to know to drive safely and economically. Speedometer and Odometer Your speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). Your odometer shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada).
Warning Lights, Gages and Indicators This part describes the warning lights and gages that may be on your vehicle. The pictures will help you locate them. Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to your warning lights and gages could also save you or others from injury. Warning lights come on when there may be or is a problem with one of your vehicle’s functions.
Air Bag Readiness Light There is an air bag readiness light on the instrument panel, which shows the air bag symbol. The system checks the air bag’s electrical system for malfunctions. The light tells you if there is an electrical problem. The system check includes the air bag sensors, the air bag modules, the wiring, the passenger air bag suppression circuit and the crash sensing and diagnostic module. For more information on the air bag system, see “Air Bag” in the Index.
Air Bag Off Light When you turn the right front passenger’s air bag off, this light will come on and stay on to remind you that the air bag has been turned off. This light will go off when you turn the air bag back on again. See “Air Bag Off Switch” in the Index for more on this, including important safety information.
Voltmeter CAUTION: If the air bag readiness light ever comes on when you have turned off the air bag, it means that something may be wrong with the air bag system. The right front passenger’s air bag could inflate even though the switch is off.
Readings in the low warning zone may occur when a large number of electrical accessories are operating in the vehicle and the engine is left at an idle for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power. You can only drive for a short time with the reading in either warning zone.
Brake System Warning Light With the ignition on, the brake system warning light will flash when you set the parking brake. The light will flash if the parking brake doesn’t release fully. If you try to drive with the parking brake engaged, a chime will sound when the vehicle speed is greater than 3 mph (5 km/h). Your vehicle’s hydraulic brake system is divided into two parts. If one part isn’t working, the other part can still work and stop you. For good braking, though, you need both parts working well.
Anti-Lock Brake System Warning Light With the anti-lock brake system, this light will come on when you start your engine and may stay on for several seconds. That’s normal. If the light stays on, or comes on when you’re driving, your vehicle needs service. If the regular brake system warning light isn’t on, you still have brakes, but you don’t have anti-lock brakes. If the regular brake system warning light is also on, you don’t have anti-lock brakes and there’s a problem with your regular brakes.
Traction Off Light (If Equipped) If you have the Traction Assist System, this light should come on briefly when you turn the ignition to RUN. If the light doesn’t come on then, the system may require service; have it fixed so it will be there to warn you if the system is turned off. If the light stays on, or comes on when you’re driving, there may be a problem with your Traction Assist System and your vehicle may need service. When this light is on, the system will not limit wheel spin.
Engine Coolant Temperature Gage United States Transmission Temperature Gage (If Equipped) Canada United States Canada This gage shows the engine coolant temperature. It also provides an indicator of how hard your vehicle is working. During a majority of the operation, the gage will read 210_F (100_C) or less. If you are pulling a load or going up hills, it is normal for the temperature to fluctuate and approach the 250_F (122_C) mark.
At approximately 265_F (130_C), the message center will display a TRANS FLUID HOT message and the transmission will enter a transmission protection mode. When the transmission enters the protection mode, you may notice a change in the transmission shifting patterns. The transmission will return to normal shifting patterns when the transmission fluid temperature falls below 260_F (127_C).
Malfunction Indicator Lamp (Service Engine Soon Light in the United States or Check Engine Light in Canada) United States This system is called OBD II (On-Board Diagnostics-Second Generation) and is intended to assure that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment. The SERVICE ENGINE SOON or CHECK ENGINE light comes on to indicate that there is a problem and service is required.
NOTICE: Modifications made to the engine, transmission, exhaust, intake or fuel system of your vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect your vehicle’s emission controls and may cause the SERVICE ENGINE SOON or CHECK ENGINE light to come on. Modifications to these systems could lead to costly repairs not covered by your warranty. This may also result in a failure to pass a required Emission Inspection/Maintenance test.
If the Light Is Flashing If the Light Is On Steady The following may prevent more serious damage to your vehicle: You may be able to correct the emission system malfunction by considering the following: D D D D Reducing vehicle speed. Did you recently put fuel into your vehicle? Avoiding hard accelerations. If so, reinstall the fuel cap, making sure to fully install the cap. See “Filling Your Tank” in the Index.
Have you recently changed brands of fuel? Emissions Inspection and Maintenance Programs If so, be sure to fuel your vehicle with quality fuel. See “Fuel” in the Index. Poor fuel quality will cause your engine not to run as efficiently as designed. You may notice this as stalling after start-up, stalling when you put the vehicle into gear, misfiring, hesitation on acceleration or stumbling on acceleration. (These conditions may go away once the engine is warmed up.
Oil Pressure Gage CAUTION: Don’t keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches fire. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced. United States Canada The oil pressure gage shows the engine oil pressure in psi (pounds per square inch) when the engine is running. Canadian vehicles indicate pressure in kPa (kilopascals).

Section 3 Comfort Controls and Audio Systems In this section, you’ll find out how to operate the comfort control and audio systems offered with your vehicle. Be sure to read about the particular systems supplied with your vehicle.
Comfort Controls Mode Knob Standard Comfort Controls The right knob on the control panel allows you to choose the direction of air delivery. (Vent): This setting directs the air through the instrument panel outlets. (Bi-Level): Air is delivered through the floor outlets as well as the instrument panel outlets. The air flow can be divided between instrument panel and floor outlets depending upon where the knob is placed between the settings.
Heater and Air Conditioning Comfort Controls (If Equipped) Mode Knob The right knob on the control panel allows you to choose the direction of air delivery. (Vent): This setting directs the air through the instrument panel outlets and the center floor console (if equipped). Fan Knob The knob on the left side of the control panel adjusts the fan speed. To increase airflow, turn the knob clockwise. To decrease airflow, turn it counterclockwise. To turn the fan off, turn the knob to OFF.
(Blend): Airflow is delivered through the floor outlets, center floor console outlets (if equipped), the windshield defroster outlets and the side window defroster outlets. The air conditioning compressor may run to dehumidify the air to prevent window fogging. (Defrost): This setting directs most of the air through the windshield defroster outlets, side window defroster outlets and some air through the floor and center floor console outlets (if equipped).
The auto recirculation feature will activate when the following are true: D The air conditioning system is activated, D the outside air button is on, and D the vehicle load is high due to city traffic, extended Electronic Climate Control System (If Equipped) idling or hot weather. The system will automatically switch to the recirculation mode to lower the system load and improve interior comfort. The outside air and recirculation button LEDs will not change.
AUTO: If the knob is in AUTO, the fan speed will vary as the system maintains the selected temperature. When both the fan control and mode knobs are in the AUTO position, the system will then automatically maintain the last selected temperature setting. Manual control of functions is also available. Temperature Knob The middle knob on the control panel lets you select the desired air temperature in your vehicle. This knob will allow you to adjust the interior air temperature setting.
(Blend): Airflow is divided equally between the floor outlet and the windshield defroster outlets. The air conditioning compressor may run to dehumidify the air to prevent window fogging. (Defrost): This setting directs most of the air through the windshield defroster outlets with airflow also delivered from the side window and the floor outlets. When in defrost mode, the air conditioning compressor may run to dehumidify the air and limit window fogging.
Mode Knob -- Automatic Operation The right knob on the control panel allows you to choose the direction of air delivery. When the system is set for automatic operation, sensors will control the air delivery mode. Air will come primarily from the floor or instrument panel outlets, with some air directed to the windshield to prevent fogging. When the system is in AUTO mode, the air conditioning light will turn on, and the recirculation and outside air lights turn off.
Air Conditioning On hot days, open the windows long enough to let hot air inside escape. This reduces the time it takes for your vehicle to cool down. Then keep your windows closed for the air conditioner to work its best. The recirculation button allows the air inside your vehicle to be recirculated. This setting helps to maximize your air conditioner’s performance and your vehicle’s fuel economy.
Heating Defogging and Defrosting The heater works best if you keep your windows closed while using it. On cold days, use the floor or bi-level setting with the temperature knob in the red area. On cool, humid days, use defrost to keep the windshield and side windows clear. Use defrost to remove fog or ice from the windshield in extremely humid or cold conditions. Use defrost with the temperature knob toward the red area and the fan control turned all the way to the right.
The defogger will shut itself off after several minutes. If you need additional warming time, press the button again. You can turn the defogger off at any time by pressing the button. If your vehicle is equipped with heated outside mirrors, the rear window defogger button will also activate the heated outside mirrors. Do not attach a temporary vehicle license, tape or decals across the defogger grid on the rear window.
Your vehicle has air outlets in the center and on the sides of your instrument panel. Ventilation Tips D Keep the hood and front air inlet free of ice, snow or any other obstruction (such as leaves). The heater and defroster will work far better, reducing the chance of fogging the inside of your windows. D When you enter a vehicle in cold weather, turn the fan knob all the way to the right for a few moments before driving.
Audio Systems Your audio system has been designed to operate easily and give years of listening pleasure. You will get the most enjoyment out of it if you acquaint yourself with it first. Find out what your audio system can do and how to operate all of its controls to be sure you’re getting the most out of the advanced engineering that went into it. Your vehicle has a feature called Retained Accessory Power (RAP). With RAP, you can play your audio system even after the ignition is turned off.

Activating the Theft-Deterrent Feature The instructions which follow explain how to enter your secret code to activate the THEFTLOCK system. It is recommended that you read through all nine steps before starting the procedure. If you allow more than 15 seconds to elapse between any steps, the radio automatically reverts to time and you must start the procedure over at Step 4. 1. Write down any three or four-digit number from 000 to 1999 and keep it in a safe place separate from the vehicle. 2.
If you enter the wrong code eight times, INOP will appear on the display. You will have to wait an hour with the ignition on before you can try again. When you try again, you will only have three chances to enter the correct code before INOP appears. If you lose or forget your code, contact your dealer. Disabling the Theft-Deterrent Feature Enter your secret code as follows; pause no more than 15 seconds between steps: 1. Turn the ignition to ACCESSORY or RUN. 2. Turn the radio off. 3.
Understanding Radio Reception AM The range for most AM stations is greater than for FM, especially at night. The longer range, however, can cause stations to interfere with each other. AM can pick up noise from things like storms and power lines. Try reducing the treble to reduce this noise if you ever get it. FM Stereo FM stereo will give you the best sound, but FM signals will reach only about 10 to 40 miles (16 to 65 km).
If this message appears on the display, your remote cassette player needs to be cleaned. It will still play tapes, but you should clean it as soon as possible to prevent damage to your tapes and player. The recommended cleaning method for your remote cassette tape player is the use of a scrubbing action, non-abrasive cleaning cassette with pads, which scrub the tape head as the hubs of the cleaner cassette turn. The recommended cleaning cassette is available through your dealer (GM Part No. 12344789).
Section 4 Your Driving and the Road Here you’ll find information about driving on different kinds of roads and in varying weather conditions. We’ve also included many other useful tips on driving.
Defensive driving really means “be ready for anything.” On city streets, rural roads or freeways, it means “always expect the unexpected.” Assume that pedestrians or other drivers are going to be careless and make mistakes. Anticipate what they might do. Be ready for their mistakes. Rear-end collisions are about the most preventable of accidents. Yet they are common. Allow enough following distance. It’s the best defensive driving maneuver, in both city and rural driving.
Drunken Driving Death and injury associated with drinking and driving is a national tragedy. It’s the number one contributor to the highway death toll, claiming thousands of victims every year. Alcohol affects four things that anyone needs to drive a vehicle: D D D D Judgment Muscular Coordination Vision Attentiveness. Police records show that almost half of all motor vehicle-related deaths involve alcohol. In most cases, these deaths are the result of someone who was drinking and driving.
Since alcohol is carried in body water, this means that a woman generally will reach a higher BAC level than a man of her same body weight when each has the same number of drinks. The law in an increasing number of U.S. states, and throughout Canada, sets the legal limit at 0.08 percent. In some other countries, the limit is even lower. For example, it is 0.05 percent in both France and Germany. The BAC limit for all commercial drivers in the United States is 0.04 percent. The BAC will be over 0.
The body takes about an hour to rid itself of the alcohol in one drink. No amount of coffee or number of cold showers will speed that up. “I’ll be careful” isn’t the right answer. What if there’s an emergency, a need to take sudden action, as when a child darts into the street? A person with even a moderate BAC might not be able to react quickly enough to avoid the collision. There’s something else about drinking and driving that many people don’t know.
Control of a Vehicle Braking You have three systems that make your vehicle go where you want it to go. They are the brakes, the steering and the accelerator. All three systems have to do their work at the places where the tires meet the road. Braking action involves perception time and reaction time. First, you have to decide to push on the brake pedal. That’s perception time. Then you have to bring up your foot and do it. That’s reaction time. Average reaction time is about 3/4 of a second.
Avoid needless heavy braking. Some people drive in spurts -- heavy acceleration followed by heavy braking -- rather than keeping pace with traffic. This is a mistake. Your brakes may not have time to cool between hard stops. Your brakes will wear out much faster if you do a lot of heavy braking. If you keep pace with the traffic and allow realistic following distances, you will eliminate a lot of unnecessary braking. That means better braking and longer brake life.
The anti-lock system can change the brake pressure faster than any driver could. The computer is programmed to make the most of available tire and road conditions. This can help you steer around the obstacle while braking hard. Let’s say the road is wet and you’re driving safely. Suddenly, an animal jumps out in front of you. You slam on the brakes and continue braking. Here’s what happens with ABS: A computer senses that wheels are slowing down.
Remember: Anti-lock doesn’t change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you won’t have time to apply your brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have anti-lock brakes. Using Anti-Lock Don’t pump the brakes. Just hold the brake pedal down firmly and let anti-lock work for you.
The Traction Assist System may operate on dry roads under some conditions. When this happens, you may notice a reduction in acceleration. This is normal and doesn’t mean there’s a problem with your vehicle. Examples of these conditions include a hard acceleration in a turn, an abrupt upshift or downshift of the transmission or driving on rough roads. If your vehicle is in cruise control when the TAS begins to limit wheel spin, the cruise control will automatically disengage.
To turn the system on or off press the TAS on/off button located to the left of the steering wheel on the instrument panel. If desired, you can change the TAS automatic engagement feature so that the system will not come on automatically when the engine is started. To do so: 1. Park the vehicle with the ignition off and the transmission in PARK (P). 2. Turn the ignition to RUN; do not start the engine. 3.
Steering Power Steering If you lose power steering assist because the engine stops or the system is not functioning, you can steer but it will take much more effort. Steering Tips Driving on Curves It’s important to take curves at a reasonable speed. A lot of the “driver lost control” accidents mentioned on the news happen on curves. Here’s why: Experienced driver or beginner, each of us is subject to the same laws of physics when driving on curves.
Steering in Emergencies There are times when steering can be more effective than braking. For example, you come over a hill and find a truck stopped in your lane, or a car suddenly pulls out from nowhere, or a child darts out from between parked cars and stops right in front of you. You can avoid these problems by braking -- if you can stop in time. But sometimes you can’t; there isn’t room. That’s the time for evasive action -- steering around the problem.
Off-Road Recovery Passing You may find that your right wheels have dropped off the edge of a road onto the shoulder while you’re driving. The driver of a vehicle about to pass another on a two-lane highway waits for just the right moment, accelerates, moves around the vehicle ahead, then goes back into the right lane again.
D Do not get too close to the vehicle you want to pass while you’re awaiting an opportunity. For one thing, following too closely reduces your area of vision, especially if you’re following a larger vehicle. Also, you won’t have adequate space if the vehicle ahead suddenly slows or stops. Keep back a reasonable distance. D When it looks like a chance to pass is coming up, start to accelerate but stay in the right lane and don’t get too close.
Loss of Control Let’s review what driving experts say about what happens when the three control systems (brakes, steering and acceleration) don’t have enough friction where the tires meet the road to do what the driver has asked. In any emergency, don’t give up. Keep trying to steer and constantly seek an escape route or area of less danger. Skidding In a skid, a driver can lose control of the vehicle.
Off-Road Driving with Your Four-Wheel-Drive Vehicle If you think you will need some more ground clearance at the front of your vehicle, you can easily remove the front bumper lower air dam. This off-road guide is for vehicles that have four-wheel drive. Also, see “Anti-Lock Brakes” in the Index. If your vehicle doesn’t have four-wheel drive, you shouldn’t drive off-road unless you’re on a level, solid surface. Off-road driving can be great fun. But it does have some definite hazards.
3. Pull the push-pins and lower air dam assembly away from the retainers until the lower air dam is free. The following steps must be performed on each of the push-pins to remove the air dam: 1. Insert a tool into the push-pin slot and pull downward until the push-pin snaps loose. When you’re back on roads, though, be sure to replace the air dam. 2. While continuing to pull downward on the push-pin, squeeze and turn the expandable end of the push-pin with a tool until it releases from the retainer.
To reinstall the lower air dam, do the following: 1. Line up each push-pin with its intended retainer and push the washer portion of the push-pin towards the retainer until it locks into place. 2. Push the flat end of the push-pin towards the retainer until it locks into place, making sure each is secure. Before You Go Off-Roading There are some things to do before you go out. For example, be sure to have all necessary maintenance and service work done.
Loading Your Vehicle for Off-Road Driving There are some important things to remember about how to load your vehicle. D The heaviest things should be on the load floor and CAUTION: D Cargo on the load floor piled higher than forward of your rear axle. Put heavier items as far forward as you can. D Be sure the load is secured properly, so driving on the off-road terrain doesn’t toss things around. D D the seatbacks can be thrown forward during a sudden stop. You or your passengers could be injured.
Environmental Concerns Off-road driving can provide wholesome and satisfying recreation. However, it also raises environmental concerns. GM recognizes these concerns and urges every off-roader to follow these basic rules for protecting the environment: D Always use established trails, roads and areas that have been specially set aside for public off-road recreational driving; obey all posted regulations.
Getting Familiar with Off-Road Driving It’s a good idea to practice in an area that’s safe and close to home before you go into the wilderness. Off-road driving does require some new and different driving skills. Here’s what we mean. Tune your senses to different kinds of signals. Your eyes, for example, need to constantly sweep the terrain for unexpected obstacles. Your ears need to listen for unusual tire or engine sounds.
Scanning the Terrain Off-road driving can take you over many different kinds of terrain. You need to be familiar with the terrain and its many different features. Here are some things to consider. Surface Conditions. Off-roading can take you over hard-packed dirt, gravel, rocks, grass, sand, mud, snow or ice. Each of these surfaces affects the steering, acceleration and braking of your vehicle in different ways.
Driving on Off-Road Hills Off-road driving often takes you up, down or across a hill. Driving safely on hills requires good judgment and an understanding of what your vehicle can and can’t do. There are some hills that simply can’t be driven, no matter how well built the vehicle. CAUTION: Many hills are simply too steep for any vehicle. If you drive up them, you will stall. If you drive down them, you can’t control your speed. If you drive across them, you will roll over.
Driving Uphill Once you decide you can safely drive up the hill, you need to take some special steps. D Use a low gear and get a firm grip on the steering wheel. D Get a smooth start up the hill and try to maintain your speed. Don’t use more power than you need, because you don’t want your wheels to start spinning or sliding. D Try to drive straight up the hill if at all possible. If the path twists and turns, you might want to find another route.
Q: A: What should I do if my vehicle stalls, or is about to stall, and I can’t make it up the hill? If this happens, there are some things you should do, and there are some things you must not do. First, here’s what you should do: D Push the brake pedal to stop the vehicle and keep it from rolling backwards. Also, apply the parking brake. D If your engine is still running, shift the transmission to REVERSE (R), release the parking brake, and slowly back down the hill in REVERSE (R).
Q: A: Suppose, after stalling, I try to back down the hill and decide I just can’t do it. What should I do? Set the parking brake, put your transmission in PARK (P) (or the manual transmission in FIRST (1)) and turn off the engine. Leave the vehicle and go get some help. Exit on the uphill side and stay clear of the path the vehicle would take if it rolled downhill. Do not shift the transfer case to NEUTRAL when you leave the vehicle. Leave it in some gear.
Driving Downhill When off-roading takes you downhill, you’ll want to CAUTION: consider a number of things: D How steep is the downhill? Will I be able to maintain vehicle control? D What’s the surface like? Smooth? Rough? Slippery? Hard-packed dirt? Gravel? D Are there hidden surface obstacles? Ruts? Logs? Boulders? D What’s at the bottom of the hill? Is there a hidden creek bank or even a river bottom with large rocks? If you decide you can go down a hill safely, then try to keep your vehicle headed
Q: Are there some things I should not do when driving down a hill? A: Q: A: Yes! These are important because if you ignore them you could lose control and have a serious accident. D Stop your vehicle by applying the regular brakes. D When driving downhill, avoid turns that take you across the incline of the hill. A hill that’s not too steep to drive down may be too steep to drive across. You could roll over if you don’t drive straight down.
Driving Across an Incline Sooner or later, an off-road trail will probably go across the incline of a hill. If this happens, you have to decide whether to try to drive across the incline. Here are some things to consider: D A hill that can be driven straight up or down may be too steep to drive across. When you go straight up or down a hill, the length of the wheel base (the distance from the front wheels to the rear wheels) reduces the likelihood the vehicle will tumble end over end.
Q: What if I’m driving across an incline that’s not too steep, but I hit some loose gravel and start to slide downhill. What should I do? A: If you feel your vehicle starting to slide sideways, turn downhill. This should help straighten out the vehicle and prevent the side slipping. However, a much better way to prevent this is to get out and “walk the course” so you know what the surface is like before you drive it.
Driving in Mud, Sand, Snow or Ice When you drive in mud, snow or sand, your wheels won’t get good traction. You can’t accelerate as quickly, turning is more difficult, and you’ll need longer braking distances. It’s best to use a low gear when you’re in mud -- the deeper the mud, the lower the gear. In really deep mud, the idea is to keep your vehicle moving so you don’t get stuck. When you drive on sand, you’ll sense a change in wheel traction. But it will depend upon how loosely packed the sand is.
If the water isn’t too deep, then drive through it slowly. At fast speeds, water splashes on your ignition system and your vehicle can stall. Stalling can also occur if you get your tailpipe under water. And, as long as your tailpipe is under water, you’ll never be able to start your engine. When you go through water, remember that when your brakes get wet, it may take you longer to stop. CAUTION: Driving through rushing water can be dangerous.
Driving at Night Here are some tips on night driving. D Drive defensively. D Don’t drink and drive. D Adjust your inside rearview mirror to reduce the glare from headlamps behind you. D Since you can’t see as well, you may need to Night driving is more dangerous than day driving. One reason is that some drivers are likely to be impaired -- by alcohol or drugs, with night vision problems, or by fatigue. 4-34 slow down and keep more space between you and other vehicles.
You can be temporarily blinded by approaching headlamps. It can take a second or two, or even several seconds, for your eyes to readjust to the dark. When you are faced with severe glare (as from a driver who doesn’t lower the high beams, or a vehicle with misaimed headlamps), slow down a little. Avoid staring directly into the approaching headlamps. Driving in Rain and on Wet Roads Keep your windshield and all the glass on your vehicle clean -- inside and out.
The heavier the rain, the harder it is to see. Even if your windshield wiper blades are in good shape, a heavy rain can make it harder to see road signs and traffic signals, pavement markings, the edge of the road and even people walking. It’s wise to keep your wiping equipment in good shape and keep your windshield washer tank filled with washer fluid.
Hydroplaning doesn’t happen often. But it can if your tires do not have much tread or if the pressure in one or more is low. It can happen if a lot of water is standing on the road. If you can see reflections from trees, telephone poles or other vehicles, and raindrops “dimple” the water’s surface, there could be hydroplaning. Driving Through Flowing Water CAUTION: Flowing or rushing water creates strong forces.
City Driving One of the biggest problems with city streets is the amount of traffic on them. You’ll want to watch out for what the other drivers are doing and pay attention to traffic signals. Here are ways to increase your safety in city driving: D Know the best way to get to where you are going. Get a city map and plan your trip into an unknown part of the city just as you would for a cross-country trip. D Try to use the freeways that rim and crisscross most large cities. You’ll save time and energy.
Freeway Driving At the entrance, there is usually a ramp that leads to the freeway. If you have a clear view of the freeway as you drive along the entrance ramp, you should begin to check traffic. Try to determine where you expect to blend with the flow. Try to merge into the gap at close to the prevailing speed. Switch on your turn signal, check your mirrors and glance over your shoulder as often as necessary. Try to blend smoothly with the traffic flow.
The exit ramp can be curved, sometimes quite sharply. Here are some things you can check before a trip: The exit speed is usually posted. D Windshield Washer Fluid: Is the reservoir full? Reduce your speed according to your speedometer, not to your sense of motion. After driving for any distance at higher speeds, you may tend to think you are going slower than you actually are. Before Leaving on a Long Trip Make sure you’re ready. Try to be well rested.
Highway Hypnosis Is there actually such a condition as “highway hypnosis”? Or is it just plain falling asleep at the wheel? Call it highway hypnosis, lack of awareness, or whatever. There is something about an easy stretch of road with the same scenery, along with the hum of the tires on the road, the drone of the engine, and the rush of the wind against the vehicle that can make you sleepy.
Hill and Mountain Roads If you drive regularly in steep country, or if you’re planning to visit there, here are some tips that can make your trips safer and more enjoyable. See “Off-Road Driving” in the Index for information about driving off-road. D Keep your vehicle in good shape. Check all fluid levels and also the brakes, tires, cooling system and transmission. These parts can work hard on mountain roads. D Know how to go down hills.
D Know how to go uphill. You may want to shift CAUTION: Coasting downhill in NEUTRAL (N) or with the ignition off is dangerous. Your brakes will have to do all the work of slowing down. They could get so hot that they wouldn’t work well. You would then have poor braking or even none going down a hill. You could crash. Always have your engine running and your vehicle in gear when you go downhill. down to a lower gear.
Winter Driving Here are some tips for winter driving: D Have your vehicle in good shape for winter. D You may want to put winter emergency supplies in your vehicle. Include an ice scraper, a small brush or broom, a supply of windshield washer fluid, a rag, some winter outer clothing, a small shovel, a flashlight, a red cloth and reflective warning triangles.
Driving on Snow or Ice Most of the time, those places where your tires meet the road probably have good traction. However, if there is snow or ice between your tires and the road, you can have a very slippery situation. You’ll have a lot less traction or “grip” and will need to be very careful. What’s the worst time for this? “Wet ice.” Very cold snow or ice can be slick and hard to drive on. But wet ice can be even more trouble because it may offer the least traction of all.
If you don’t have a traction system, accelerate gently. Try not to break the gentle traction. If you accelerate too fast, the drive wheels will spin and polish the surface under the tires even more. If You’re Caught in a Blizzard Your anti-lock brakes improve your vehicle’s stability when you make a hard stop on a slippery road. Even though you have an anti-lock braking system, you’ll want to begin stopping sooner than you would on dry pavement. See “Anti-Lock” in the Index.
D Tie a red cloth to your vehicle to alert police that you’ve been stopped by the snow. D Put on extra clothing or wrap a blanket around you. If you have no blankets or extra clothing, make body insulators from newspapers, burlap bags, rags, floor mats -- anything you can wrap around yourself or tuck under your clothing to keep warm. CAUTION: Snow can trap exhaust gases under your vehicle. This can cause deadly CO (carbon monoxide) gas to get inside. CO could overcome you and kill you.
Then, shut the engine off and close the window almost all the way to preserve the heat. Start the engine again and repeat this only when you feel really uncomfortable from the cold. But do it as little as possible. Preserve the fuel as long as you can. To help keep warm, you can get out of the vehicle and do some fairly vigorous exercises every half hour or so until help comes.
Dinghy Towing When towing your vehicle, turn the ignition off. To prevent your battery from draining while towing, remove the IGN 0 fuse from the instrument panel fuse block. Be sure to reinstall the fuse when you reach your destination. See “Fuses and Circuit Breakers” in the Index. Two-Wheel-Drive Vehicles Two-wheel-drive vehicles, should not be towed with all four wheels on the ground. Two-wheel-drive transmissions have no provisions for internal lubrication while being towed.
Four-Wheel-Drive Vehicles 4. Shift the transfer case to NEUTRAL. See “Four-Wheel Drive” in the Index for the proper procedure to select the neutral position for your vehicle. 5. Release the parking brake only after the vehicle being towed is firmly attached to the towing vehicle. 6. Turn the ignition off. CAUTION: Use the following procedure to tow your vehicle: 1. Firmly set the parking brake. 2. Shift an automatic transmission to PARK (P), or a manual transmission to FIRST (1). 3.
Dolly Towing (Two-Wheel Drive Vehicles) Two-Wheel-Drive Vehicles Two-wheel-drive vehicles, should not be towed with the rear wheels on the ground. Two-wheel-drive transmissions have no provisions for internal lubrication while being towed. To properly tow these vehicles, they should be placed on a platform trailer with all four wheels off the ground.
Loading Your Vehicle The Certification/Tire label also tells you the maximum weights for the front and rear axles, called Gross Axle Weight Rating (GAWR). To find out the actual loads on your front and rear axles, you need to go to a weigh station and weigh your vehicle. Your dealer can help you with this. Be sure to spread out your load equally on both sides of the centerline. Never exceed the GVWR for your vehicle, or the GAWR for either the front or rear axle.
CAUTION: Do not load your vehicle any heavier than the GVWR, or either the maximum front or rear GAWR. If you do, parts on your vehicle can break, and it can change the way your vehicle handles. These could cause you to lose control and crash. Also, overloading can shorten the life of your vehicle. NOTICE: Your warranty does not cover parts or components that fail because of overloading. This will help you decide how much cargo and installed equipment your truck can carry.
Payload 2-Tiered Loading The payload capacity is shown on the Certification/Tire label. This is the maximum load capacity that your vehicle can carry. Be sure to include the weight of the occupants as part of your load. If you added any accessories or equipment after your vehicle left the factory, remember to subtract the weight of these things from the payload. Your dealer can help you with this.
Add-On Equipment When you carry removable items, you may need to put a limit on how many people you carry inside your vehicle. Be sure to weigh your vehicle before you buy and install the new equipment. NOTICE: Your warranty doesn’t cover parts or components that fail because of overloading. Remember not to exceed the Gross Axle Weight Rating (GAWR) of the front or rear axle. See “Loading Your Vehicle” in the Index. *Equipment Maximum Weight Ladder Rack and Cargo . . . . . . . . . . 750 lbs.
Q: How do I know if my vehicle can handle a snow plow? A: Some vehicles are built with a special package, called RPO VYU (snow plow prep package). If your vehicle has this option, you can add a plow to it, provided certain weights, such as the weights on the vehicle’s axles and the GVW, aren’t exceeded.
Q: What is front axle reserve capacity, and how do I calculate it? A: Front axle reserve capacity is the difference between your front GAWR and the front axle weight of your truck with full fuel and passengers. Basically, it’s the amount of weight you can add to your front axle before reaching your front GAWR.
For example, adding a 700 lb. (318 kg) snow plow actually adds more than 700 lb. (318 kg) to the front axle. Using the formula, if the snow plow is 4 ft. (122 cm) in front of the front axle and the wheel base is 10 ft. (305 cm), then: W=700 lb. (318 kg) A=4 ft. (122 cm) W.B.=10 ft. (305 cm) (W x (A + W.B.))/W.B.= (700 x (4 + 10))/10 = 980 lb. (445 kg) So, if your truck’s front axle reserve capacity is more than 980 lb. (445 kg), you could add this snow plow without exceeding the front GAWR.
CAUTION: On some vehicles equipped with certain front mounted equipment, such as a snow plow, it may be possible to load the front axle to the front GAWR but not have enough weight on the rear axle to have proper braking performance. If your brakes can’t work properly, you could have a crash.
Truck-Camper Loading Information This label is inside your glove box. It will tell you if your vehicle can carry a slide-in camper, how much of a load your vehicle can carry, and how to correctly spread out your load. Also, it will help you match the right slide-in camper to your vehicle. Refer to the Truck-Camper Loading Information label in glove box for dimensions A and B as shown in the following illustration.
Here is an example of proper truck and camper match: Your dealer can help you make a good vehicle-camper match. He’ll also help you determine your CWR. After you’ve loaded your vehicle and camper, drive to a weigh station and weigh the front and rear wheels separately. This will tell you the loads on your axles. The loads on the front and rear axles shouldn’t be more than either of the GAWRs. The total of the axle loads should not be more than the GVWR.
Trailer Recommendations You must subtract your hitch loads from the CWR for your vehicle. Weigh your vehicle with the trailer attached, so that you won’t go over the GVWR or GAWR. If you are using a weight-distributing hitch, weigh the vehicle without the equalizer bars in place. You’ll get the best performance if you spread out the weight of your load the right way, and if you choose the correct hitch and trailer brakes. For more information, see “Trailer Towing” in the Index.
Towing a Trailer CAUTION: If you don’t use the correct equipment and drive properly, you can lose control when you pull a trailer. For example, if the trailer is too heavy, the brakes may not work well -- or even at all. You and your passengers could be seriously injured. Pull a trailer only if you have followed all the steps in this section. Ask your dealer for advice and information about towing a trailer with your vehicle.
If You Do Decide To Pull A Trailer If you do, here are some important points: D There are many different laws, including speed limit restrictions, having to do with trailering. Make sure your rig will be legal, not only where you live but also where you’ll be driving. A good source for this information can be state or provincial police. D Consider using a sway control if your trailer will weigh less than 5,000 lbs. (2 270 kg) for light duty vehicles, or less than 7,500 lbs.
Tow/Haul Mode (If Equipped) Tow/haul is a feature on automatic transmission equipped vehicles that assists when pulling a heavy trailer or a large or heavy load. The purpose of the tow/haul mode is to: D Reduce the frequency and improve the predictability of transmission shifts when pulling a heavy trailer or a large or heavy load. D Provide the same solid shift feel when pulling a heavy trailer or a large or heavy load as when the vehicle is unloaded.
Weight of the Trailer How heavy can a trailer safely be? It depends on how you plan to use your rig. For example, speed, altitude, road grades, outside temperature and how much your vehicle is used to pull a trailer are all important. And, it can also depend on any special equipment that you have on your vehicle. Use one of the following charts to determine how much your vehicle can weigh, based upon your vehicle model and options.

You can ask your dealer for our trailering information or advice, or you can write us at the address listed in your Warranty and Owner Assistance Information Booklet. In Canada, write to: General Motors of Canada Limited Customer Communication Centre, 163-005 1908 Colonel Sam Drive Oshawa, Ontario L1H 8P7 Weight of the Trailer Tongue The tongue load (A) of any trailer is an important weight to measure because it affects the total or gross weight of your vehicle.
Total Weight on Your Vehicle’s Tires Safety Chains Be sure your vehicle’s tires are inflated to the upper limit for cold tires. You’ll find these numbers on the Certification label at the rear edge of the driver’s door or see “Tire Loading” in the Index. Then be sure you don’t go over the GVW limit for your vehicle, including the weight of the trailer tongue. You should always attach chains between your vehicle and your trailer.
Trailer Brakes Driving with a Trailer If your trailer weighs more than 2,000 lbs. (900 kg) loaded, then it needs its own brakes -- and they must be adequate. Be sure to read and follow the instructions for the trailer brakes so you’ll be able to install, adjust and maintain them properly. Towing a trailer requires a certain amount of experience. Before setting out for the open road, you’ll want to get to know your rig.
Following Distance Stay at least twice as far behind the vehicle ahead as you would when driving your vehicle without a trailer. This can help you avoid situations that require heavy braking and sudden turns. Passing You’ll need more passing distance up ahead when you’re towing a trailer. And, because you’re a good deal longer, you’ll need to go much farther beyond the passed vehicle before you can return to your lane. Backing Up Hold the bottom of the steering wheel with one hand.
Driving On Grades Reduce speed and shift to a lower gear before you start down a long or steep downgrade. If you don’t shift down, you might have to use your brakes so much that they would get hot and no longer work well. If you have an automatic transmission, you can tow in DRIVE (D). You may want to shift the transmission to THIRD (3) or, if necessary, a lower gear selection if the transmission shifts too often (e.g., under heavy loads and/or hilly conditions).
Parking on Hills CAUTION: You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could start to move. People can be injured, and both your vehicle and the trailer can be damaged. But if you ever have to park your rig on a hill, here’s how to do it: 1. Apply your regular brakes, but don’t shift into PARK (P) yet for an automatic transmission, or into gear for a manual transmission. 2. Have someone place chocks under the trailer wheels. 3.
When You Are Ready to Leave After Parking on a Hill 1. Apply your regular brakes and hold the pedal down while you: D start your engine, D shift into a gear, and D release the parking brake. 2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear of the chocks. 4. Stop and have someone pick up and store the chocks. 4-90 Maintenance When Trailer Towing Your vehicle will need service more often when you’re pulling a trailer. See the Maintenance Schedule for more on this.
Trailer Wiring Harness Your vehicle is equipped with one of the following wiring harnesses for towing a trailer or hauling a slide-in camper. Basic Trailer Wiring Package All regular, extended cab crew cab pickups have a six-wire trailer towing harness. The six-wire harness is located at the rear of the vehicle and is tied to the vehicle’s frame. The harness requires the installation of a trailer-wiring harness connector, which is available through your dealer.
Heavy-Duty Trailer Wiring Package (If Equipped) The eight-wire harness contains the following trailer circuits: D D D D D D D D Your pickup may be equipped with the eight-wire trailer towing harness. This harness with a seven-pin universal heavy-duty trailer connector is attached to a bracket on the platform hitch.* * The Center High-Mounted Stoplamp (CHMSL) wire is tied next to the trailer wiring harness for use with a trailer, slide-in camper or cap.
Camper/Fifth-Wheel Trailer Wiring Package (If Equipped) The eight-wire camper harness is located under the front edge of the pickup box on the driver’s side of the vehicle, attached to the frame bracket. A connector will have to be added to the wiring harness which connects to the camper.
Instrument Panel Jumper Wiring Harness Four Wire Trailer Harness Adapter If you need to tow a light-duty trailer with a standard four-way round pin connector, an adapter connector is included with your vehicle. Connect the adapter with the tab (arrow) pointing towards the top. The cap on the wiring harness will lock onto the tab (arrow) and help hold the adapter in place. This harness is included with the heavy-duty and camper/fifth-wheel trailer wiring packages.
Auxiliary Battery (If Equipped) The auxiliary battery provision can be used to supply electrical power to additional equipment that you may choose to add, such as a slide-in camper. If your vehicle has this provision, this relay will be located on the passenger’s side of the vehicle, next to the auxiliary battery. The auxiliary battery circuit is protected by a megafuse located behind the auxiliary battery.
Power Winches 3. Shift the transmission into NEUTRAL (N). If you wish to use a power winch on your vehicle, only use it when your vehicle is stationary or anchored. 4. Engage the PTO. Refer to the manufacturer’s or installer’s for instructions on electrically engaged PTOs. NOTICE: Using a power winch with the transmission in gear may damage the transmission. When operating a power winch, always leave the transmission in NEUTRAL (N).
To use PTO speed control in Preset Mode (Factory Setting) do the following: 1. Engage the PTO 2. Select PARK (P) or NEUTRAL (N) range. Apply the parking brake if NEUTRAL (N) is selected. Torque Converter Clutch (TCC) is not available in NEUTRAL (N) and is available only in PARK (P) when engine speed is above 1100 rpm. 3. Make sure your foot is off the brake pedal (and off the clutch on vehicles equipped with a manual transmission). 4. Select the desired engine speed for PTO operation.
To use PTO speed control in variable mode (while stationary) do the following: 1. Engage the PTO. 2. Vehicle speed must be less than 5 mph. 3. Make sure your foot is off the brake pedal (and off the clutch for vehicles equipped with a manual transmission). 4. Select the desired engine speed by using the foot pedal, and select SET on the PTO switch or the cruise control. Variable Mode: PTO speed control mode can be used for both stationary and mobile applications.
Section 5 Problems on the Road Here you’ll find what to do about some problems that can occur on the road.
Hazard Warning Flashers The hazard warning flasher button is located at the top of the steering column. Your hazard warning flashers work no matter what position your key is in, and even if the key isn’t in. Press the button to make the front and rear turn signal lamps flash on and off. Press the button again to turn the flashers off. Your hazard warning flashers let you warn others. They also let police know you have a problem. Your front and rear turn signal lamps will flash on and off.
Jump Starting If your battery (or batteries) has run down, you may want to use another vehicle and some jumper cables to start your vehicle. Be sure to follow the steps below to do it safely. CAUTION: Batteries can hurt you. They can be dangerous because: D They contain acid that can burn you. D They contain gas that can explode or ignite. D They contain enough electricity to burn you. If you don’t follow these steps exactly, some or all of these things can hurt you.
2. If you have a vehicle with a diesel engine with two batteries (or more), you should know before you begin that, especially in cold weather, you may not be able to get enough power from a single battery in another vehicle to start your diesel engine. If your vehicle has more than one battery, use the battery that’s closer to the starter -- this will reduce electrical resistance. 3. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles aren’t touching each other.
5. Open the hoods and locate the positive (+) and negative (-) terminal locations of the other vehicle. Your vehicle has a remote positive (+) jump starting terminal and a remote negative (-) jump starting terminal. You should always use these remote terminals instead of the terminals on the battery. The remote positive (+) terminal is located behind a red plastic cover near the engine accessory drive bracket. To uncover the remote positive (+) terminal, open the red plastic cover.
CAUTION: Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running. 6. Check that the jumper cables don’t have loose or missing insulation. If they do, you could get a shock. The vehicles could be damaged too. Before you connect the cables, here are some basic things you should know. Positive (+) will go to positive (+) or a remote positive terminal (+) if the vehicle has one.
8. Don’t let the other end touch metal. Connect it to the positive (+) terminal of the good battery. Use a remote positive (+) terminal if the vehicle has one. 9. Now connect the black negative (-) cable to the negative (-) terminal of the good battery. Use a remote negative (-) terminal if the vehicle has one. Don’t let the other end touch anything until the next step. The other end of the negative (-) cable doesn’t go to the dead battery.
NOTICE: Damage to your vehicle may result from electrical shorting if jumper cables are removed incorrectly. To prevent electrical shorting take care that they don’t touch each other or any other metal. The repairs wouldn’t be covered by your warranty. V8 Engine V6 Engine, Diesel Similar 10. Connect the other end of the negative (-) cable to the negative (-) terminal of the dead battery or to a remote negative (-) terminal if the vehicle has one. 11.
To disconnect the jumper cables from both vehicles do the following: 1. Disconnect the black negative (-) cable from the vehicle that had the bad battery. 2. Disconnect the black negative (-) cable from the vehicle with the good battery. 3. Disconnect the red positive (+) cable from the vehicle with the good battery. 4. Disconnect the red positive (+) cable from the other vehicle. 5. Return the positive (+) remote terminal cover to its original position. Jumper Cable Removal A.
Engine Overheating You will find a coolant temperature gage on your vehicle’s instrument panel. See “Engine Coolant Temperature Gage” in the Index. In addition, you will find a LOW COOLANT, CHECK COOLANT TEMP, ENGINE OVERHEATED and a REDUCED ENGINE POWER message in the message center on the instrument panel. See “Message Center” in the Index.
If Steam Is Coming From Your Engine CAUTION: (Continued) Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool. See “Overheated Engine Protection Operating Mode” in the Index. NOTICE: CAUTION: Steam from an overheated engine can burn you badly, even if you just open the hood.
If No Steam Is Coming From Your Engine An overheat warning, along with a low coolant message, can indicate a serious problem. See “Low Coolant Message” in the Index. If you get an engine overheat warning with no low coolant message, but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you: D D D D Climb a long hill on a hot day. Stop after high-speed driving. Idle for long periods in traffic. Tow a trailer. See “Driving on Grades” in the Index.
Cooling System (Gasoline Engine) When you decide it’s safe to lift the hood, here’s what you’ll see: All Other Engines A. Coolant Surge Tank B. Coolant Surge Tank Pressure Cap 8100 V8 Engines C. Engine Fan If the coolant inside the coolant surge tank is boiling, don’t do anything else until it cools down. The vehicle should be parked on a level surface.
The coolant level should be at or above the FILL COLD mark. If it isn’t, you may have a leak at the pressure cap or in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system. CAUTION: Heater and radiator hoses, and other engine parts, can be very hot. Don’t touch them. If you do, you can be burned. Don’t run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned.
NOTICE: Engine damage from running your engine without coolant isn’t covered by your warranty. See “Overheated Engine Protection Operating Mode” in the Index. How to Add Coolant to the Coolant Surge Tank --Gasoline Engines If you haven’t found a problem yet, check to see if coolant is visible in the surge tank.
If no coolant is visible in the surge tank, add coolant as follows: CAUTION: Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the coolant surge tank pressure cap -- even a little -- they can come out at high speed. Never turn the cap when the cooling system, including the coolant surge tank pressure cap, is hot. Wait for the cooling system and coolant surge tank pressure cap to cool if you ever have to turn the pressure cap.
CAUTION: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you wouldn’t get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX-COOLR coolant.
Your vehicle may be equipped with one of the two caps shown. 1. Park the vehicle on a level surface. You can remove the coolant surge tank pressure cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise (left) about one full turn. If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left. 2. Then keep turning the pressure cap slowly, and remove it. 5-18 3.
4. With the coolant surge tank pressure cap off, start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan. 5. Then replace the pressure cap. Be sure the pressure cap is hand-tight and fully seated. By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mixture to the coolant surge tank until the level reaches the FILL COLD mark.
Engine Fan Noise If a Tire Goes Flat Your vehicle has a clutched engine cooling fan. When the clutch is engaged, the fan spins faster to provide more air to cool the engine. In most everyday driving conditions, the fan is spinning slower and the clutch is not fully engaged. This improves fuel economy and reduces fan noise. Under heavy vehicle loading, trailer towing and/or high outside temperatures, the fan speed increases as the clutch more fully engages. So you may hear an increase in fan noise.
Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning flashers. CAUTION: CAUTION: (Continued) 4. Turn off the engine. 5. Put the wheel blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire on the other side of the vehicle, at the opposite end. Changing a tire can cause an injury. The vehicle can slip off the jack and roll over you or other people.
Removing the Spare Tire and Tools Extended and Crew CabR Regular Cab 5-22 The equipment you’ll need is behind the passenger’s seat. For Extended and Crew Cab models, the equipment is under the passenger’s side second row seat.
1. If there is a cover, move the seats forward and turn the wing nut on the cover counterclockwise to remove it. For Crew Cab models, pull up the second row seat with the loop at the base of the seat cushion to access the tools. 2. The wheel blocks and the wheel block retainer can be removed by turning the wing nut counterclockwise. 3. To release the bottle jack from its holder, turn the knob on the bottle jack counterclockwise to lower the jack head. 4.
Follow these instructions to lower the spare tire: 1. If the vehicle is equipped with a hoist lock, open the spare tire lock cover on the bumper and use the ignition key to remove the lock. 2. Assemble the wheel wrench and the two jack handle extensions as shown. Insert the hoist end (open end) of the extension through the hole in the rear bumper. Be sure the hoist end of the extension connects into the hoist shaft. 3. Turn the wheel wrench counterclockwise to lower the spare tire to the ground.
Attach the wheel wrench to the jack handle extensions (as needed). Attach the jack handle to the jack. Turn the wheel wrench clockwise to raise the jack lift head a little.
If your vehicle has wheel nut caps, loosen them by turning the wheel wrench counterclockwise. If you have a center cap with wheel nut caps, the wheel nut caps are designed to remain with the center cap. Removing the Flat Tire and Installing the Spare Tire 1. Use the wheel wrench to loosen all the wheel nuts. Turn the wheel wrench counterclockwise to loosen the wheel nuts. Don’t remove the wheel nuts yet. Remove the center cap.
CAUTION: Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack, you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack. 2. Position the jack under the vehicle. If the flat tire is on the front of the vehicle (Two-Wheel Drive 1500 Series vehicles), position the jack under the bracket attached to the vehicle’s frame, behind the flat tire.
Front Position All Other Models Front Position 2WD 1500 Series 5-28
4. Remove all the wheel nuts and take off the flat tire. Rear Position 3. Make sure the jack head is positioned so that the rear axle is resting securely between the grooves that are on the jack head. Turn the wheel wrench clockwise to raise the vehicle. Raise the vehicle far enough off the ground so there is enough room for the spare tire to fit under the wheel well. 5. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel.
CAUTION: Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from the places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off. CAUTION: Never use oil or grease on studs or nuts.
Front Position 2WD 1500 Series Front Position All Other Models 5-31
8. Tighten the nuts firmly in a crisscross sequence as shown by turning the wheel wrench clockwise. Rear Position 7. Turn the wheel wrench counterclockwise to lower the vehicle. Lower the jack completely.
CAUTION: Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to become loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque. See “Capacities and Specifications” in the Index.
Storing a Flat or Spare Tire and Tools CAUTION: Storing a jack, a tire or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place. Return the bottle jack, wheel blocks, wheel wrench and jack extensions to their location behind the passenger’s seat. Secure the items in the vehicle as shown. 5-34 A. Wing Nut B. Wheel Blocks C. Wheel Wrench and Extensions Retainer D. Gloves E.
Store the tire under the rear of the vehicle in the spare tire carrier. To store the tire, do the following: 1. Put the tire on the ground at the rear of the vehicle with the valve stem pointed downward and to the rear. 2. Tilt the retainer downward and through the wheel opening. Make sure that the retainer is fully seated across the underside of the wheel. 3. Attach the wheel wrench and extensions together. Insert the hoist end through the hole in the rear bumper and into the hoist shaft. 4.
If You’re Stuck: In Sand, Mud, Ice or Snow In order to free your vehicle when it is stuck, you will need to spin the wheels, but you don’t want to spin your wheels too fast. The method known as “rocking” can help you get out when you’re stuck, but you must use caution. CAUTION: 6. Make sure the tire is stored securely. Push, pull, and then try to rotate or turn the tire. If the tire moves, use the wheel wrench/hoist shaft to tighten the cable. Put back the jack, tools and spare tire lock.
NOTICE: Spinning your wheels can destroy parts of your vehicle as well as the tires. If you spin the wheels too fast while shifting your transmission back and forth, you can destroy your transmission. For information about using tire chains on your vehicle, see “Tire Chains” in the Index. Rocking Your Vehicle To Get It Out First, turn your steering wheel left and right. That will clear the area around your front wheels. If you have a four-wheel-drive vehicle, shift into 4HI.
Using the Recovery Hooks Your vehicle may be equipped with recovery hooks. The hooks are provided at the front of your vehicle. You may need to use them if you’re stuck off-road and need to be pulled to some place where you can continue driving.
CAUTION: These hooks, when used, are under a lot of force. Always pull the vehicle straight out. Never pull on the hooks at a sideways angle. The hooks could break off and you or others could be injured from the chain or cable snapping back. NOTICE: Never use the recovery hooks to tow the vehicle. Your vehicle could be damaged and it would not be covered by warranty.
✍ 5-40 NOTES
Section 6 Service and Appearance Care Here you will find information about the care of your vehicle. This section begins with service and fuel information, and then it shows how to check important fluid and lubricant levels. There is also technical information about your vehicle, and a part devoted to its appearance care.
Service Doing Your Own Service Work Your dealer knows your vehicle best and wants you to be happy with it. We hope you’ll go to your dealer for all your service needs. You’ll get genuine GM parts and GM-trained and supported service people. If you want to do some of your own service work, you’ll want to use the proper service manual. It tells you much more about how to service your vehicle than this manual can. To order the proper service manual, see “Service and Owner Publications” in the Index.
CAUTION: You can be injured and your vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it. D Be sure you have sufficient knowledge, experience, the proper replacement parts and tools before you attempt any vehicle maintenance task. D Be sure to use the proper nuts, bolts and other fasteners. “English” and “metric” fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt.
Gasoline Specifications California Fuel It is recommended that gasoline meet specifications which were developed by the American Automobile Manufacturers Association and endorsed by the Canadian Vehicle Manufacturers’ Association for better vehicle performance and engine protection. Gasolines meeting these specifications could provide improved driveability and emission control system performance compared to other gasolines.
Additives Some gasolines that are not reformulated for low emissions may contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. General Motors does not recommend the use of such gasolines. Fuels containing MMT can reduce the life of spark plugs and the performance of the emission control system may be affected. The malfunction indicator lamp may turn on.
Filling Your Tank The fuel cap is located behind a hinged door on the driver’s side of the vehicle. If your vehicle is a chassis cab, you will have a second fuel cap. CAUTION: Gasoline vapor is highly flammable. It burns violently, and that can cause very bad injuries. Don’t smoke if you’re near gasoline or refueling your vehicle. Keep sparks, flames and smoking materials away from gasoline. If your vehicle has a diesel engine, see “Filling Your Tank (Diesel Engine)” in the Diesel Engine Supplement.
CAUTION: If you get gasoline on yourself and then something ignites it, you could be badly burned. Gasoline can spray out on you if you open the fuel cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel cap slowly and wait for any “hiss” noise to stop. Then unscrew the cap all the way. Be careful not to spill gasoline. Clean gasoline from painted surfaces as soon as possible. See “Cleaning the Outside of Your Vehicle” in the Index.
Filling a Portable Fuel Container CAUTION: Never fill a portable fuel container while it is in your vehicle. Static electricity discharge from the container can ignite the gasoline vapor. You can be badly burned and your vehicle damaged if this occurs. To help avoid injury to you and others: D Dispense gasoline only into approved containers. D Do not fill a container while it is inside a vehicle, in a vehicle’s trunk, pickup bed or on any surface other than the ground.

Noise Control System The following information relates to compliance with federal noise emission standards for vehicles with a Gross Vehicle Weight Rating (GVWR) of more than 10,000 lbs. (4 536 kg). The Maintenance Schedule provides information on maintaining the noise control system to minimize degradation of the noise emission control system during the life of your vehicle. The noise control system warranty is given in your warranty booklet.
Engine Oil (Gasoline Engine) If your vehicle has a diesel engine, see “Engine Oil (Diesel Engine)” in the Diesel Engine Supplement. If the CHECK ENG OIL LEVEL light appears on the instrument cluster, it means you need to check your engine oil level right away. For more information, see “CHECK ENG OIL LEVEL” in the Index. You should check your engine oil level regularly; this is an added reminder. Checking Engine Oil It’s a good idea to check your engine oil every time you get fuel.
Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level. NOTICE: Don’t add too much oil. If your engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, your engine could be damaged. When to Add Engine Oil If the oil is at or below the ADD mark then you’ll need to add at least one quart of oil. But you must use the right kind.
Your vehicle may have a cap with text and a graphic, or just a graphic as shown. What Kind of Engine Oil to Use Oils recommended for your vehicle can be identified by looking for the starburst symbol. This symbol indicates that the oil has been certified by the American Petroleum Institute (API). Do not use any oil which does not carry this starburst symbol. The engine oil fill cap for the VORTEC 4800, 5300 and 6000 V8 engines is located on the engine valve cover on the passenger’s side of the vehicle.
As in the chart shown previously, SAE 5W-30 is best for your vehicle. However, you can use SAE 10W-30 if it’s going to be 0 F (-18 C) or above. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils, such as SAE 20W-50. _ _ NOTICE: Use only engine oil with the American Petroleum Institute Certified For Gasoline Engines starburst symbol. Failure to use the recommended oil can result in engine damage not covered by your warranty.
Engine Oil Additives Don’t add anything to your oil. The recommended oils with the starburst symbol are all you will need for good performance and engine protection. When to Change Engine Oil (GM Oil Life System ) t Your vehicle has a computer system that lets you know when to change the engine oil and filter. This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably.
What to Do with Used Oil Used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer. Don’t let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly throw away clothing or rags containing used engine oil. See the manufacturer’s warnings about the use and disposal of oil products. Used oil can be a threat to the environment.
Your engine air cleaner/filter is located in the front corner of the engine compartment on the passenger’s side of the vehicle. See “Engine Compartment Overview” in the Index for more information on location. 1. To remove the engine air cleaner/filter, loosen the screws on the housing cover. Lift the cover upward. 2. Lift the filter from the air cleaner housing. Care should be taken to dislodge as little dirt as possible. 3. Clean the filter sealing surface and the filter housing. 4.
CAUTION: Operating the engine with the air cleaner/filter off can cause you or others to be burned. The air cleaner not only cleans the air, it stops flame if the engine backfires. If it isn’t there, and the engine backfires, you could be burned. Don’t drive with it off, and be careful working on the engine with the air cleaner/filter off. NOTICE: If the air cleaner/filter is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it.
3. Remove the air filter by pulling downward on the element. Remove the second portion of the air filter by sliding it towards the rear of the vehicle and then pulling downward. Automatic Transmission Fluid (Except Allison Transmission) 4. Install the new filter by reversing the steps listed previously. Be sure to follow any instructions that may be included in the replacement filter package. A good time to check your automatic transmission fluid level is when the engine oil is changed.
How to Check Because this operation can be a little difficult, you may choose to have this done at the dealership service department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick. NOTICE: Too much or too little fluid can damage your transmission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Too little fluid could cause the transmission to overheat.
Checking the Fluid Level Prepare your vehicle as follows: D Park your vehicle on a level place. Keep the engine running. D With the parking brake applied, place the shift lever in PARK (P). D With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, position the shift lever in PARK (P). D Let the engine run at idle for three minutes or more.
How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See “Recommended Fluids and Lubricants” in the Index. Add fluid only after checking the transmission fluid while it is hot. (A cold check is used only as a reference.) If the fluid level is low, add only enough of the proper fluid to bring the level up to the HOT area for a hot check. It doesn’t take much fluid, generally less than one pint (0.5 L). Don’t overfill. 3.
Automatic Transmission Fluid (AllisonR Only) When to Check and Change A good time to check your automatic transmission fluid level is when the engine oil is changed. How to Check Because this operation can be a little difficult, you may choose to have this done at the dealership service department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick.
Checking the Fluid Level Cold Check Procedure Prepare your vehicle as follows: The purpose of the cold check is to determine if the transmission has enough fluid to be operated safely until a hot check can be made. The fluid level rises as fluid temperature increases. DO NOT fill above the COLD CHECK band if the transmission fluid is below normal operating temperatures. D Park your vehicle on a level place. Keep the engine running. D With the parking brake applied, place the shift lever in PARK (P).
Hot Check Procedure Consistency of Readings The fluid must be hot to ensure an accurate check. The fluid level rises as temperature increases. Always check the fluid level at least twice using the procedures described previously. Consistency (repeatable readings) is important to maintaining proper fluid level. If inconsistent readings persist, check the transmission breather to be sure it is clean and unclogged. If readings are still inconsistent, contact your dealer. 1.
NOTICE: We recommend you use only fluid labeled DEXRONR-III, because fluid with that label is made especially for your automatic transmission. Damage caused by fluid other than DEXRONR-III is not covered by your new vehicle warranty. D After adding fluid, recheck the fluid level as described under “How to Check.” D When the correct fluid level is obtained, push the dipstick back in all the way. Manual Transmission Fluid When to Check A good time to have it checked is when the engine oil is changed.
Then, follow these steps: How to Add Fluid Here’s how to add fluid. Refer to the Maintenance Schedule to determine what kind of fluid to use. See “Recommended Fluids and Lubricants” in the Index. 1. Remove the filler plug. 2. Add fluid at the filler plug hole. Add only enough fluid to bring the fluid level up to the bottom of the filler plug hole. 3. Install the filler plug. Be sure the plug is fully seated. 5-Speed for VORTEC 4300 V6 and 4800 V8 Engines Shown, Other Manual Transmissions Similar 1.
Hydraulic Clutch The hydraulic clutch linkage in your vehicle is self-adjusting. The clutch master cylinder reservoir is filled with hydraulic clutch fluid. It is not necessary to regularly check clutch fluid unless you suspect there is a leak in the system. Adding fluid won’t correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.
Refer to the Maintenance Schedule to determine how often to check the lubricant. See “Scheduled Maintenance Services” in the Index. The proper level for the 1500 Series is from 5/8 inch to 1 5/8 inch (15 mm to 40 mm) below the bottom of the filler plug hole. The proper level for the 2500 Series is from 0 to 3/8 inch (0 to 10 mm) below the bottom of the filler plug hole. The proper level for the 2500 HD and 3500 Series is just below the bottom of the filler plug hole.
How to Check Lubricant Automatic Transfer Case Manual Transfer Case To get an accurate reading, the vehicle should be on a level surface. If the level is below the bottom of the filler plug hole, you’ll need to add some lubricant. Add enough lubricant to raise the level to the bottom of the filler plug hole. Use care not to overtighten the plug. What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use. See “Recommended Fluids and Lubricants” in the Index.
Front Axle When to Check Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant. See “Scheduled Maintenance Services” in the Index. How to Check Lubricant To get an accurate reading, the vehicle should be on a level surface. If the level is below the bottom of the filler plug hole, you may need to add some lubricant. When the differential is cold, add enough lubricant to raise the level to 1/2 inch (12 mm) below the filler plug hole.
Engine Coolant The cooling system in your vehicle is filled with DEX-COOLR engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOLR extended life coolant. The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating, see “Engine Overheating” in the Index.
What to Use Use a mixture of one-half clean, drinkable water and one-half DEX-COOLR coolant which won’t damage aluminum parts. If you use this coolant mixture, you don’t need to add anything else. CAUTION: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture.
Checking Coolant The coolant surge tank is located in the engine compartment on the passenger’s side of the vehicle. See “Engine Compartment Overview” in the Index for more information on location. The vehicle must be on a level surface. When your engine is cold, the coolant level should be at the FILL COLD mark. If the LOW COOLANT message comes on and stays on, it means you’re low on engine coolant. See “Low Coolant” in the Index.
Your vehicle may be equipped with one of the two caps shown. Coolant Surge Tank Pressure Cap The coolant surge tank pressure cap must be fully installed on the coolant surge tank. NOTICE: Your coolant surge tank pressure cap is a 15 psi (105 kPa) pressure-type cap and must be tightly installed to prevent coolant loss and possible engine damage from overheating.
Power Steering Fluid All Other Engines 8100 V8 Engine 6-39
When to Check Power Steering Fluid Windshield Washer Fluid It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. See “Engine Compartment Overview” in the Index for reservoir location.
NOTICE: D When using concentrated washer fluid, D D D follow the manufacturer’s instructions for adding water. Don’t mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage your washer fluid tank and other parts of the washer system. Also, water doesn’t clean as well as washer fluid. Fill your washer fluid tank only three-quarters full when it’s very cold. This allows for expansion if freezing occurs, which could damage the tank if it is completely full.
So, it isn’t a good idea to “top off” your brake fluid. Adding brake fluid won’t correct a leak. If you add fluid when your linings are worn, then you’ll have too much fluid when you get new brake linings. You should add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system. Checking Brake Fluid CAUTION: If you have too much brake fluid, it can spill on the engine. The fluid will burn if the engine is hot enough.
What to Add When you do need brake fluid, use only DOT-3 brake fluid. Refer to “Recommended Fluids and Lubricants” in the Index. Use new brake fluid from a sealed container only. NOTICE: D Using the wrong fluid can badly damage Always clean the brake fluid reservoir cap and the area around the cap before removing it. This will help keep dirt from entering the reservoir. CAUTION: With the wrong kind of fluid in your brake system, your brakes may not work well, or they may not even work at all.
Brake Wear Your vehicle has four-wheel disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and go or be heard all the time your vehicle is moving (except when you are pushing on the brake pedal firmly). Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes.
Replacing Brake System Parts Battery The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Your vehicle was designed and tested with top-quality GM brake parts. When you replace parts of your braking system -- for example, when your brake linings wear down and you need new ones put in -- be sure you get new approved GM replacement parts. If you don’t, your brakes may no longer work properly.
Vehicle Storage Bulb Replacement If you’re not going to drive your vehicle for 25 days or more, remove the black, negative (-) cable from the battery. This will help keep your battery from running down. For any bulb changing procedure not listed in this section, contact your dealer. CAUTION: Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you aren’t careful. See “Jump Starting” in the Index for tips on working around a battery without getting hurt.

Windshield Wiper Blade Replacement Windshield wiper blades should be inspected at least twice a year for wear and cracking. See “Wiper Blade Check” in the Index for more information. Replacement blades come in different types and are removed in different ways. For proper type and length, see “Normal Maintenance Replacement Parts” in the Index. To replace the windshield wiper blade assembly, do the following: 1. Lift the wiper arm and turn the blade until it is facing away from the windshield. 2.
Tires Your new vehicle comes with high-quality tires made by a leading tire manufacturer. If you ever have questions about your tire warranty and where to obtain service, see your GM Warranty booklet for details. CAUTION: (Continued) D Underinflated tires pose the same danger CAUTION: Poorly maintained and improperly used tires are dangerous. D Overloading your tires can cause overheating as a result of too much friction. You could have an air-out and a serious accident.
Inflation -- Tire Pressure The Certification/Tire label, which is on the rear edge of the driver’s door, shows the correct inflation pressures for your tires when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). NOTICE: Don’t let anyone tell you that underinflation or overinflation is all right. It’s not.
Tire Inspection and Rotation Tires should be rotated every 6,000 to 8,000 miles (10 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See “When It’s Time for New Tires” and “Wheel Replacement” later in this section for more information. Make sure the spare tire is stored securely. Push, pull, and then try to rotate or turn the tire. If it moves, use the wheel wrench/hoist shaft to tighten the cable.
The dual tires are rotated as a pair, and the inside rear tires become the outside rear tires. When you install dual wheels, be sure the vent holes in the inner and outer wheels on each side are lined up. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Certification/Tire label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” in the Index.
When It’s Time for New Tires One way to tell when it’s time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining. Some commercial truck tires may not have treadwear indicators. You need a new tire if any of the following statements are true: D You can see the indicators at three or more places around the tire. D You can see cord or fabric showing through the tire’s rubber.
Buying New Tires To find out what kind and size of tires you need, look at the Certification/Tire label. The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) number on each tire’s sidewall. When you get new tires, get ones with that same TPC Spec number. That way your vehicle will continue to have tires that are designed to give proper endurance, handling, speed rating, traction, ride and other things during normal service on your vehicle.
Uniform Tire Quality Grading Treadwear Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and a half (1 1/2) times as well on the government course as a tire graded 100.
Temperature -- A, B, C Wheel Alignment and Tire Balance The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure.
Wheel Replacement Replace any wheel that is bent, cracked, or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your dealer if any of these conditions exist. Your dealer will know the kind of wheel you need.
Used Replacement Wheels NOTICE: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance and tire or tire chain clearance to the body and chassis. Whenever a wheel, wheel bolt or wheel nut is replaced on a dual wheel setup, check the wheel nut torque after 100, 1,000 and 6,000 miles (160, 1 600 and 10 000 km) of driving. For proper torque, see “Wheel Nut Torque” in the Index.
Tire Chains CAUTION: If your vehicle has dual wheels or P265/75R16 or LT265/75R16 size tires, don’t use tire chains. They can damage your vehicle because there’s not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension or other vehicle parts. The area damaged by the tire chains could cause you to lose control of your vehicle and you or others may be injured in a crash.
Appearance Care Remember, cleaning products can be hazardous. Some are toxic. Others can burst into flame if you strike a match or get them on a hot part of the vehicle. Some are dangerous if you breathe their fumes in a closed space. When you use anything from a container to clean your vehicle, be sure to follow the manufacturer’s warnings and instructions. And always open your doors or windows when you’re cleaning the inside.
Cleaning of Fabric/Carpet Your dealer has cleaners for the cleaning of fabric and carpet. They will clean normal spots and stains very well. You can get GM-approved cleaning products from your dealer. See “Appearance Care and Materials” in the Index. Here are some cleaning tips: D D D D Always read the instructions on the cleaner label. Clean up stains as soon as you can -- before they set. Carefully scrape off any excess stain. Use a clean cloth or sponge, and change to a clean area often.
Stains caused by candy, ice cream, mayonnaise, chili sauce and unknown stains can be removed as follows: 1. Carefully scrape off excess stain. 2. First, clean with cool water and allow to dry completely. 3. If a stain remains, follow the cleaner instructions described earlier. Cleaning Vinyl Use warm water and a clean cloth. D Rub with a clean, damp cloth to remove dirt. You may have to do it more than once. D Things like tar, asphalt and shoe polish will stain if you don’t get them off quickly.
Cleaning Interior Plastic Components Cleaning Glass Surfaces Use only a mild soap and water solution on a soft cloth or sponge. Commercial cleaners may affect the surface finish. Glass should be cleaned often. GM Glass Cleaner or a liquid household glass cleaner will remove normal tobacco smoke and dust films on interior glass. See “Appearance Care and Materials” in the Index. Care of Safety Belts Keep belts clean and dry. CAUTION: Do not bleach or dye safety belts.
Cleaning the Outside of the Windshield and Wiper Blades If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax, sap or other material may be on the blade or windshield. Clean the outside of the windshield with a full-strength glass cleaning liquid. The windshield is clean if beads do not form when you rinse it with water. Grime from the windshield will stick to the wiper blades and affect their performance.
Cleaning Exterior Lamps/Lenses Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses. Follow instructions under “Washing Your Vehicle.” Finish Care Occasional waxing or mild polishing of your vehicle by hand may be necessary to remove residue from the paint finish. You can get GM-approved cleaning products from your dealer. See “Appearance Care and Materials” in the Index. Your vehicle has a “basecoat/clearcoat” paint finish.
Cleaning Aluminum or Chrome-Plated Wheels (If Equipped) Keep your wheels clean using a soft clean cloth with mild soap and water. Rinse with clean water. After rinsing thoroughly, dry with a soft clean towel. A wax may then be applied. The surface of these wheels is similar to the painted surface of your vehicle. Don’t use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid or abrasive cleaning brushes on them because you could damage the surface.
Finish Damage Chemical Paint Spotting Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare metal will corrode quickly and may develop into a major repair expense. Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on your vehicle. This damage can take two forms: blotchy, ringlet-shaped discolorations, and small irregular dark spots etched into the paint surface.

Normal Maintenance Replacement Parts Replacement part numbers listed in this section are based on the latest information available at the time of printing, and are subject to change. If a part listed in this manual is not the same as the part used in your vehicle when it was built, or if you have any questions, please contact your GM dealer. These specifications are for information only. If you have any questions, see the service manual for the chassis or refer to the body manufacturer’s publications.
Section 7 Maintenance Schedule This section covers the maintenance required for your vehicle. Your vehicle needs these services to retain its safety, dependability and emission control performance.
Introduction Your Vehicle and the Environment Proper vehicle maintenance not only helps to keep your vehicle in good working condition, but also helps the environment. All recommended maintenance procedures are important. Improper vehicle maintenance can even affect the quality of the air we breathe. Improper fluid levels or the wrong tire inflation can increase the level of emissions from your vehicle.
How This Section is Organized This maintenance schedule is divided into five parts: “Part A: Scheduled Maintenance Services” explains what to have done and how often. Some of these services can be complex, so unless you are technically qualified and have the necessary equipment, you should let your dealer’s service department or another qualified service center do these jobs. CAUTION: Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, you can be seriously injured.
Part A: Scheduled Maintenance Services Using Your Maintenance Schedule We at General Motors want to help you keep your vehicle in good working condition. But we don’t know exactly how you’ll drive it. You may drive very short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands or in many other ways.
Scheduled Maintenance The services shown in this schedule up to 100,000 miles (166 000 km) should be repeated after 100,000 miles (166 000 km) at the same intervals for the life of this vehicle. The services shown at 150,000 miles (240 000 km) and 200,000 miles (332 000 km) should be repeated at the same intervals after 150,000 miles (240 000 km) and 200,000 miles (332 000 km) for the life of this vehicle. See “Owner Checks and Services” and “Periodic Maintenance Inspections” following. Footnotes [ The U.
Scheduled Maintenance Engine Oil and Chassis Lubrication Scheduled Maintenance Change engine oil and filter as indicated by the GM Oil Life Systemt (or every 12 months, whichever occurs first). Reset the system. Your vehicle has a computer system that lets you know when to change the engine oil and filter. This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably.
