yellowblue How to Use this Manual Safety Warnings and Symbols Many people read their owner’s manual from beginning to end when they first receive their new vehicle. If you do this, it will help you learn about the features and controls for your vehicle. In this manual, you’ll find that pictures and words work together to explain things quickly. You will find a number of safety cautions in this book.
yellowblue You will also find a circle with a slash through it in this book. This safety symbol means “Don’t,” “Don’t do this” or “Don’t let this happen.” In the notice area, we tell you about something that can damage your vehicle. Many times, this damage would not be covered by your warranty, and it could be costly. But the notice will tell you what to do to help avoid the damage. When you read other manuals, you might see CAUTION and NOTICE warnings in different colors or in different words.

yellowblue 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.
yellowblue 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. If your vehicle has a manual bucket, split bench or full bench seat, you can adjust it with this lever at the front of the seat. 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.
yellowblue Power Driver’s Seat (Option) The switch located at the front of this control panel is for the power lumbar adjustment, which is explained next. Power Lumbar Control If you have power lumbar adjustment, you can increase or decrease lumbar support in an area of the lower seatback. If your vehicle has a power seat on the driver’s side, you can adjust it with these controls at the outside edge of the seat. You can use the round center knob to move the seat to where you want it.
yellowblue Reclining Seatbacks To adjust the front seatback, move the lever rearward. Release the lever to lock the seatback where you want it. Move the lever again rearward and the seatback will go to an upright position. 1-4 But don’t have a seatback reclined if your vehicle is moving.
yellowblue 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 because it won’t be against your body. Instead, it will be in front of you. 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.
yellowblue To fold a front split bench or bucket seatback forward, pull this lever forward and fold the seatback forward. To return the seatback to the upright position, just push the seatback rearward until it latches. After returning the seatback to its upright position, pull the seatback forward to make sure it is locked. Easy Entry Seat (Extended Cab Only) The manual driver and passenger front bucket seats and the manual 60/40 split bench seat of your vehicle have an easy entry feature.
yellowblue After returning the seat to its regular position, try to move the seat with your body to make sure the seat is locked into place. CAUTION: If any easy entry seat isn’t locked, it can move. In a sudden stop or crash, the person sitting there could be injured. And, even if there is no crash or sudden stop, a driver sitting in an unlocked easy entry seat could be startled by the sudden movement and hit the wrong control or pedal, causing an accident.
yellowblue 2. Lift the entire seat and push it rearward into place. Rear Seat (Crew Cab) The rear seatback without a center armrest can be folded forward to let you reach the area behind it. Your seatback will move back and forth freely, unless you come to a sudden stop. Then, it will lock into place. The rear seatback with a center armrest folds forward to let you access the area behind it. To fold a seatback forward, pull this lever forward and fold the seatback forward. 3. Make sure the seat is secure.
yellowblue Safety Belts: They’re for Everyone This part of the manual tells you how to use safety belts properly. It also tells you some things you should not do with safety belts. And it explains the air bag system. CAUTION: Don’t let anyone ride where he or she can’t wear a safety belt properly. If you are in a crash and you’re not wearing a safety belt, your injuries can be much worse. You can hit things inside the vehicle or be ejected from it. You can be seriously injured or killed.
yellowblue In most states and Canadian provinces, the law says to wear safety belts. Here’s why: They work. 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. Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. A few crashes are mild, and some crashes can be so serious that even buckled up a person wouldn’t survive. But most crashes are in between. In many of them, people who buckle up can survive and sometimes walk away.
yellowblue Put someone on it. Get it up to speed. Then stop the vehicle. The rider doesn’t stop.
yellowblue The person keeps going until stopped by something. In a real vehicle, it could be the windshield ... 1-12 or the instrument panel ...
yellowblue 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? 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. A: You could be -- whether you’re wearing a safety belt or not.
yellowblue Q: If I’m a good driver, and I never drive far from home, why should I wear safety belts? A: You may be an excellent driver, but if you’re in an accident -- even one that isn’t your fault -- you and your passengers can be hurt. Being a good driver doesn’t protect you from things beyond your control, such as bad drivers. Most accidents occur within 25 miles (40 km) of home. And the greatest number of serious injuries and deaths occur at speeds of less than 40 mph (65 km/h).
yellowblue 3. Pick up the latch plate and pull the belt across you. Don’t let it get twisted. 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.
yellowblue Shoulder Belt Height Adjuster Before you begin to drive, move the shoulder belt adjuster to the height that is right for you. To move it down, push in at the word PRESS and move the height adjuster to the desired position. You can move the adjuster up just by pushing up on the shoulder belt guide. After you move the adjuster to where you want it, try to move it down without pushing in to make sure it has locked into position.
yellowblue 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.
yellowblue 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.
yellowblue 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.
yellowblue 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.
yellowblue 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.
yellowblue 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.
yellowblue 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.
yellowblue Here are the most important things to know about the air bag system: CAUTION: You can be severely injured or killed in a crash if you aren’t wearing your safety belt -- even if you have air bags. Wearing your safety belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it. Air bags are “supplemental restraints” to the safety belts. All air bags -- even Next Generation air bags -- are designed to work with safety belts, but don’t replace them.
yellowblue CAUTION: Children who are up against, or very close to, any air bag when it inflates can be seriously injured or killed. This is true even though your vehicle has Next Generation frontal air bags. Air bags plus lap-shoulder belts offer the best protection for adults, but not for young children and infants. Neither the vehicle’s safety belt system nor its air bag system is designed for them. Young children and infants need the protection that a child restraint system can provide.
yellowblue How the Air Bag System Works The right front passenger’s air bag is in the instrument panel on the passenger’s side. Where are the air bags? The driver’s air bag is in the middle of the steering wheel.
yellowblue 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. 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. When should an air bag inflate? An air bag is designed to inflate in a moderate to severe frontal or near-frontal crash.
yellowblue How does an air bag restrain? In moderate to severe frontal or near-frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. Air bags supplement the protection provided by safety belts. Air bags distribute the force of the impact more evenly over the occupant’s upper body, stopping the occupant more gradually.
yellowblue In many crashes severe enough to inflate an air bag, windshields are broken by vehicle deformation. Additional windshield breakage may also occur from the right front passenger air bag. D Air bags are designed to inflate only once. After they inflate, you’ll need some new parts for your air bag system. If you don’t get them, the air bag system won’t be there to help protect you in another crash. A new system will include air bag modules and possibly other parts.
yellowblue AIR BAG OFF Switch If your vehicle has air bags, it also has a switch on the instrument panel that you can use to turn off the right front passenger’s air bag. Infant.
yellowblue 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.
yellowblue 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.
yellowblue 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.
yellowblue Adding Equipment to Your Air Bag-Equipped Vehicle Q: What if I add a snow plow? Will it keep the air bags from working properly? Q: If I add a push bumper or a bicycle rack to the front of my vehicle, will it keep the air bags from working properly? A: A: As long as the push bumper or bicycle rack is attached to your vehicle so that the vehicle’s basic structure isn’t changed, it’s not likely to keep the air bags from working properly in a crash.
yellowblue Center Passenger Position Lap Belt If your vehicle has front and rear bench seats, someone can sit in the center positions.
yellowblue Front (All) When you sit in a center seating position, you have a lap safety belt, which has no retractor. To make the belt longer, tilt the latch plate and pull it along the belt.
yellowblue 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.
yellowblue Lap-Shoulder Belt (Extended 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. If the belt stops before it reaches the buckle, tilt the latch plate and keep pulling until you can buckle it. 1. Pick up the latch plate and pull the belt across you. Don’t let it get twisted. Pull up on the latch plate to make sure it is secure.
yellowblue 3. To make the lap part tight, pull down on the buckle end of the belt as you pull up on the shoulder part. 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.
yellowblue The safety belt locks if there’s a sudden stop or a crash. 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.
yellowblue Rear Seat Outside Passenger Positions (Crew Cab) If you have an Extended Cab, see “Rear Seat Outside Passenger Positions (Extended Cab)” earlier in this section. Lap-Shoulder Belt (Crew Cab) The positions next to the windows have lap-shoulder belts. Here’s how to wear one properly. 1. Pick up the latch plate and pull the belt across you. Don’t let it get twisted. 2. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure.
yellowblue 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. 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.
yellowblue There is one guide for each outside passenger position in the rear seat. To provide added safety belt comfort for children who have outgrown child restraints and for smaller adults, the comfort guides may be installed on the shoulder belts. Here’s how to install a comfort guide and use the safety belt: To unlatch the belt, just push the button on the buckle.
yellowblue 1. Remove the guide from its storage clip on the side of the seatback. 2. Slide the guide under and past the belt. The elastic cord must be under the belt. Then, place the guide over the belt, and insert the two edges of the belt into the slots of the guide. 1-44 3. Be sure that the belt is not twisted and it lies flat. The elastic cord must be under the belt and the guide on top.
yellowblue To remove and store the comfort guides, squeeze the belt edges together so that you can take them out from the guides. Slide the guide onto the storage clip. Make sure you remove the comfort guide from the belt before you fold a rear seat down or use an easy-entry seat, if your vehicle has one. Children Everyone in a vehicle needs protection! That includes infants and all children smaller than adult size.
yellowblue Smaller Children and Babies CAUTION: Children who are up against, or very close to, any air bag when it inflates can be seriously injured or killed. This is true even though your vehicle has Next Generation frontal air bags. Air bags plus lap-shoulder belts offer the best protection for adults, but not for young children and infants. Neither the vehicle’s safety belt system nor its air bag system is designed for them.
yellowblue CAUTION: (Continued) at only 25 mph (40 km/h), a 12-lb. (5.5 kg) baby will suddenly become a 240-lb. (110 kg) force on your arms. The baby would be almost impossible to hold. Secure the baby in an infant restraint. CAUTION: Never hold a baby in your arms while riding in a vehicle. A baby doesn’t weigh much -- until a crash. During a crash a baby will become so heavy you can’t hold it.
yellowblue Child Restraints Every time infants and young children ride in vehicles, they should have protection provided by appropriate restraints. Q: What are the different types of add-on child restraints? A: Add-on child restraints are available in four basic types. When selecting a child restraint, take into consideration not only the child’s weight and size, but also whether or not the restraint will be compatible with the motor vehicle in which it will be used.
yellowblue A rear-facing infant restraint (B) positions an infant to face the rear of the vehicle. Rear-facing infant restraints are designed for infants of up to about 20 lbs. (9 kg) and about one year of age. This type of restraint faces the rear so that the infant’s head, neck and body can have the support they need in a frontal crash. Some infant seats come in two parts -- the base stays secured in the vehicle and the seat part is removable.
yellowblue A forward-facing child restraint (C-E) positions a child upright to face forward in the vehicle. These forward-facing restraints are designed to help protect children who are from 20 to 40 lbs. (9 to 18 kg) and about 26 to 40 inches (66 to 102 cm) in height, or up to around four years of age. One type, a convertible restraint, is designed to be used either as a rear-facing infant seat or a forward-facing child seat.
yellowblue A booster seat (F, G) is designed for children who are about 40 to 60 lbs., or even up to 80 lbs. (18 to 27 kg, or even up to 36 kg), and about four to eight years of age. A booster seat is designed to improve the fit of the vehicle’s safety belt system. Booster seats with shields use lap-only belts; however, booster seats without shields use lap-shoulder belts. Booster seats can also help a child to see out the window.
yellowblue When choosing a child restraint, be sure the child restraint is designed to be used in a vehicle. If it is, it will have a label saying that it meets Federal Motor Vehicle Safety Standards. Then follow the instructions for the restraint. You may find these instructions on the restraint itself or in a booklet, or both. These restraints use the belt system in your vehicle, but the child also has to be secured within the restraint to help reduce the chance of personal injury.
yellowblue Top Strap CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates, even though your vehicle has Next Generation frontal air bags. 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.
yellowblue Securing a Child Restraint in a Rear Outside Seat Position (Extended Cab) If you have a Crew Cab, see “Securing a Child Restraint in a Rear Outside Seat Position (Crew Cab)” later in this section. 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. Put the restraint on the seat. 2.
yellowblue 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. 4. To tighten the belt, pull up on the shoulder belt 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. Make sure the buckle end of the belt is pulled out all the way.
yellowblue 5. 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. Securing a Child Restraint in a Rear Outside Seat Position (Crew Cab) If you have an Extended Cab, see “Securing a Child Restraint in a Rear Outside Seat Position (Extended Cab)” earlier in this section.
yellowblue 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. 4. Pull the rest of the lap belt all the way out of the retractor to set the lock.
yellowblue 5. To tighten the belt, feed the lap 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.
yellowblue Securing a Child Restraint in a Center Seat Position 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. Rear (Extended and Crew Cab) See the earlier part about the top strap if the child restraint has one.
yellowblue Front (All) 1. Make the belt as long as possible by tilting the latch plate and pulling it along the belt. 2. Put the restraint on the seat. 3. Run the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how.
yellowblue 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. 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. It will be ready to work for an adult or larger child passenger. Front (All) 4. Buckle the belt.
yellowblue Securing a Child Restraint in the Right Front Seat Position (Regular Cab Pickup and Crew Cab) 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. Put the restraint on the seat. 2.
yellowblue 4. Pull the rest of the lap belt all the way out of the retractor to set the lock. 6. Push and pull the child restraint in different directions to be sure it is secure. 5. To tighten the belt, feed the lap 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.
yellowblue Securing a Child Restraint in the Right Front Seat Position (Extended Cab Pickup) If your vehicle has air bags, there’s a switch on the instrument panel that you can use to turn off the right front passenger’s air bag when you want to secure a rear-facing child restraint at the right front passenger’s position. See “AIR BAG OFF Switch” in the Index for more on this, including important safety information.
yellowblue 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.
yellowblue 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. 1-66 5. Pull the rest of the lap belt all the way out of the retractor to set the lock.
yellowblue 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 your vehicle has air bags, 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. See “AIR BAG OFF Switch” in the Index. CAUTION: 6.
yellowblue Larger Children If you have the choice, a child should sit next to a window so the child can wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. Accident statistics show that children are safer if they are restrained in the rear seat. But they need to use the safety belts properly. D Children who aren’t buckled up can be thrown out in a crash. D Children who aren’t buckled up can strike other people who are.
yellowblue 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.
yellowblue 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.
yellowblue 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.
yellowblue ✍ 1-72 NOTES
yellowblue 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.
yellowblue 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 power windows or other controls or even make the vehicle move. Don’t leave the keys in a vehicle with children.
yellowblue Your vehicle has one double-sided key for the ignition and all door locks. 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 away from you into the latch. After you put the tailgate back up, pull it back toward you to be sure that it latches securely. Tailgate Removal If you ever lose your keys, your dealer will be able to assist you with obtaining new ones.
yellowblue To remove the tailgate: Third Door (If Equipped) 1. Raise the tailgate slightly and release both retaining cable clips. To release the retaining cable clips, pull the retaining cable clip away from the cable end. Lift the cable so it points straight out and push the cable clips forward. 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.
yellowblue Door Locks CAUTION: Unlocked doors can be dangerous. Passengers -- especially children -- can easily open the doors and fall out. When a door is locked, the inside handle won’t open it. Outsiders can easily enter through an unlocked door when you slow down or stop your vehicle. This may not be so obvious: You increase the chance of being thrown out of the vehicle in a crash if the doors aren’t locked.
yellowblue Power Door Locks (If Equipped) Press the top of the power door lock switch, marked LOCK, on either front door to lock all the doors at once. Press the ribbed side of the switch to unlock all the doors at once. Your interior lamps will be illuminated for a set period of time when the transmitter signal is received by the Keyless Entry System. In addition, your vehicle’s horn will chirp if you press the LOCK button twice, to let you know that the doors have locked.
yellowblue This system has a range of about 3 feet (1 m) up to 30 feet (9 m). At times you may notice a decrease in range. This is normal for any remote keyless entry system. If the transmitter does not work or if you have to stand closer to your vehicle for the transmitter to work, try this: Press the LOCK button to lock all the doors. The interior lamps will come on for two seconds as soon as all the doors are closed.
yellowblue Battery Replacement To replace the battery: Under normal use, the battery in your remote keyless entry transmitter should last about two years. 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.
yellowblue Resynchronization 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 it has been sent previously. This prevents anyone from recording and playing back the signal from the transmitter. When you park your vehicle and open the driver’s door, you’ll hear a tone reminding you to remove your key from the ignition and take it with you. Always do this.
yellowblue PasslockR Your vehicle is equipped with the Passlock theft-deterrent system. Passlock is a passive theft-deterrent system. Passlock enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder is tampered with, fuel is disabled. During normal operation, the SECURITY light will go off approximately five seconds after the key is turned to the RUN ignition position.
yellowblue Ignition Positions CAUTION: Leaving children in a vehicle with the ignition key is dangerous for many reasons. A child or others could be injured or even killed.

yellowblue ✍ 3-28 NOTES
yellowblue 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.
yellowblue 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.
yellowblue 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.
yellowblue 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 many U.S. states sets the legal limit at a BAC of 0.10 percent. In a growing number of U.S. states, and throughout Canada, the limit is 0.08 percent. In some other countries, it’s even lower. The BAC limit for all commercial drivers in the United States is 0.04 percent. The BAC will be over 0.
yellowblue 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.
yellowblue Average reaction time is about 3/4 of a second. But that’s only an average. It might be less with one driver and as long as two or three seconds or more with another. Age, physical condition, alertness, coordination and eyesight all play a part. So do alcohol, drugs and frustration. But even in 3/4 of a second, a vehicle moving at 60 mph (100 km/h) travels 66 feet (20 m). That could be a lot of distance in an emergency, so keeping enough space between your vehicle and others is important.
yellowblue If your engine ever stops while you’re driving, brake normally but don’t pump your brakes. If you do, the pedal may get harder to push down. If your engine stops, you will still have some power brake assist. But you will use it when you brake. Once the power assist is used up, it may take longer to stop and the brake pedal will be harder to push. Anti-Lock Brakes (ABS) Your vehicle has anti-lock brakes (ABS). ABS is an advanced electronic braking system that will help prevent a braking skid.
yellowblue 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. 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.
yellowblue 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. Speed Sensitive Steering This system varies the amount of steering effort proportionate to your vehicle speed. Steering is easier at lower speeds for maneuvering and parking ease. As your vehicle speed increases, the steering effort also increases.
yellowblue 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.
yellowblue 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.
yellowblue 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.
yellowblue 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.
yellowblue Off-Road Driving with Your Four-Wheel-Drive Vehicle 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. The greatest of these is the terrain itself. “Off-roading” means you’ve left the great North American road system behind.
yellowblue CAUTION: D Cargo on the load floor piled higher than D D the seatbacks can be thrown forward during a sudden stop. You or your passengers could be injured. Keep cargo below the top of the seatbacks. Unsecured cargo on the load floor can be tossed about when driving over rough terrain. You or your passengers can be struck by flying objects. Secure the cargo properly. Heavy loads on the roof raise the vehicle’s center of gravity, making it more likely to roll over.
yellowblue Traveling to Remote Areas It makes sense to plan your trip, especially when going to a remote area. Know the terrain and plan your route. You are much less likely to get bad surprises. Get accurate maps of trails and terrain. Try to learn of any blocked or closed roads. It’s also a good idea to travel with at least one other vehicle. If something happens to one of them, the other can help quickly. Does your vehicle have a winch? If so, be sure to read the winch instructions.
yellowblue 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.
yellowblue 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. incline may get steeper as you near the top, but you may not see this because the crest of the hill is hidden by bushes, grass or shrubs. Here are some other things to consider as you approach a hill.
yellowblue 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.
yellowblue Q: What should I do if my vehicle stalls, or is about to stall, and I can’t make it up the hill? A: 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).
yellowblue 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 (N) when you leave the vehicle. Leave it in some gear.
yellowblue 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? Heavy braking when going down a hill can cause your brakes to overheat and fade. This could cause loss of control and a serious accident.
yellowblue Q: A: Am I likely to stall when going downhill? It’s much more likely to happen going uphill. But if it happens going downhill, here’s what to do. D Stop your vehicle by applying the regular brakes. Apply the parking brake. D Shift to PARK (P) (or to NEUTRAL (N) with the manual transmission) and, while still braking, restart the engine. D Shift back to a low gear, release the parking brake, and drive straight down. D If the engine won’t start, get out and get help.
yellowblue Stalling on an Incline CAUTION: Driving across an incline that’s too steep will make your vehicle roll over. You could be seriously injured or killed. If you have any doubt about the steepness of the incline, don’t drive across it. Find another route instead. 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.
yellowblue CAUTION: Getting out on the downhill (low) side of a vehicle stopped across an incline is dangerous. If the vehicle rolls over, you could be crushed or killed. Always get out on the uphill (high) side of the vehicle and stay well clear of the rollover path. 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.
yellowblue Driving in Water Light rain causes no special off-road driving problems. But heavy rain can mean flash flooding, and flood waters demand extreme caution. Find out how deep the water is before you drive through it. If it’s deep enough to cover your wheel hubs, axles or exhaust pipe, don’t try it -- you probably won’t get through. Also, water that deep can damage your axle and other vehicle parts. If the water isn’t too deep, then drive through it slowly.
yellowblue Your vehicle will require more frequent service due to off-road use. Refer to the Maintenance Schedule for additional information. 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. 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.
yellowblue Night Vision No one can see as well at night as in the daytime. But as we get older these differences increase. A 50-year-old driver may require at least twice as much light to see the same thing at night as a 20-year-old. What you do in the daytime can also affect your night vision. For example, if you spend the day in bright sunshine you are wise to wear sunglasses. Your eyes will have less trouble adjusting to night. But if you’re driving, don’t wear sunglasses at night.
yellowblue Rain and wet roads can mean driving trouble. On a wet road, you can’t stop, accelerate or turn as well because your tire-to-road traction isn’t as good as on dry roads. And, if your tires don’t have much tread left, you’ll get even less traction. It’s always wise to go slower and be cautious if rain starts to fall while you are driving. The surface may get wet suddenly when your reflexes are tuned for driving on dry pavement. The heavier the rain, the harder it is to see.
yellowblue CAUTION: Wet brakes can cause accidents. They won’t work as well in a quick stop and may cause pulling to one side. You could lose control of the vehicle. After driving through a large puddle of water or a car wash, apply your brake pedal lightly until your brakes work normally. Hydroplaning Hydroplaning is dangerous. So much water can build up under your tires that they can actually ride on the water. This can happen if the road is wet enough and you’re going fast enough.
yellowblue City Driving 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. (See the next part, “Freeway Driving.”) D Treat a green light as a warning signal. A traffic light is there because the corner is busy enough to need it.
yellowblue 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.
yellowblue The exit speed is usually posted. 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. If you must start when you’re not fresh -- such as after a day’s work -- don’t plan to make too many miles that first part of the journey.
yellowblue What can you do about highway hypnosis? First, be aware that it can happen. Hill and Mountain Roads Then here are some tips: D Make sure your vehicle is well ventilated, with a comfortably cool interior. D Keep your eyes moving. Scan the road ahead and to the sides. Check your mirrors and your instruments frequently. D If you get sleepy, pull off the road into a rest, service or parking area and take a nap, get some exercise, or both.
yellowblue 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. The most important thing to know is this: let your engine do some of the slowing down. Shift to a lower gear when you go down a steep or long hill. CAUTION: If you don’t shift down, your brakes could get so hot that they wouldn’t work well.
yellowblue 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.
yellowblue 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.
yellowblue D Watch for slippery spots. The road might be fine until you hit a spot that’s covered with ice. On an otherwise clear road, ice patches may appear in shaded areas where the sun can’t reach: around clumps of trees, behind buildings or under bridges. Sometimes the surface of a curve or an overpass may remain icy when the surrounding roads are clear. If you see a patch of ice ahead of you, brake before you are on it.
yellowblue If you are stopped by heavy snow, you could be in a serious situation. You should probably stay with your vehicle unless you know for sure that you are near help and you can hike through the snow. Here are some things to do to summon help and keep yourself and your passengers safe: D Turn on your hazard flashers. 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.
yellowblue 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. You can’t see it or smell it, so you might not know it is in your vehicle. Clear away snow from around the base of your vehicle, especially any that is blocking your exhaust pipe. And check around again from time to time to be sure snow doesn’t collect there. Open a window just a little on the side of the vehicle that’s away from the wind.
yellowblue Recreational Vehicle Towing There may be times when you want to tow your vehicle behind another vehicle for use at your destination. Be sure to use the proper towing equipment designed for recreational vehicle towing. Follow the instructions for the towing equipment. 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.
yellowblue Four-Wheel-Drive Vehicles CAUTION: Shifting the transfer case into NEUTRAL (N) can cause your vehicle to roll even if the transmission is in PARK (P), for an automatic transmission, or if your vehicle is in gear, for a manual transmission. You or others could be injured. Make sure the parking brake is firmly set before you shift the transfer case into NEUTRAL (N). Vehicles equipped with the electronic transfer case cannot be towed with all four wheels on the ground.
yellowblue 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.
yellowblue Using heavier suspension components to get added durability might not change your weight ratings. Ask your dealer to help you load your vehicle the right way. NOTICE: (Continued) D For the front axle, if more cargo or NOTICE: Some vehicles may be equipped with RPO VYU (snow plow prep package). With this option, the payload your vehicle can carry is reduced when a snow plow is installed. Your vehicle can be damaged if either the front or rear axle ratings, or the GVW are exceeded.
yellowblue NOTICE: Your warranty does not cover parts or components that fail because of overloading. CAUTION: (Continued) D When you carry something inside the vehicle, secure it whenever you can. D Don’t leave a seat folded down unless you need to. If you put things inside your vehicle -- like suitcases, tools, packages, or anything else -- they go as fast as the vehicle goes. If you have to stop or turn quickly, or if there is a crash, they’ll keep going.
yellowblue The Cargo Weight Rating (CWR) is the maximum weight of the load your vehicle can carry. It doesn’t include the weight of the people inside. But, you can figure about 150 lbs. (68 kg) for each seating position. The total cargo load must not be more than your vehicle’s CWR. 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: A. Camper Center of Gravity B.
yellowblue If your slide-in camper and its load weighs less than the CWR, the center of gravity zone for your vehicle may be larger. 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.
yellowblue Camper Wiring Harness (If Equipped) D D D D D Brown: Rear Lamps Yellow: Left Stoplamp and Turn Signal Dark Green: Right Stoplamp and Turn Signal White (Heavy Gage): Ground Light Green: Back-up Lamps When the harness is not being used, store it in its original place. Wrap the harness together and tie it neatly so it won’t be damaged. Pickup Conversion to Chassis Cab A five-wire harness may be stored under your vehicle.
yellowblue 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.
yellowblue 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 the capacity stamped on your step bumper.
yellowblue Use one of the following charts to determine how much your vehicle can weigh, based upon your vehicle model and options. Maximum trailer weight is calculated assuming the driver and one passenger are in the tow vehicle and it has all the required trailering equipment. The weight of additional optional equipment, passengers and cargo in the tow vehicle must be subtracted from the maximum trailer weight. Above the 2,000 lbs.

yellowblue If you’re using a weight-carrying hitch, the trailer tongue (A) should weigh 10 percent of the total loaded trailer weight (B). If you’re using a weight-distributing hitch, the trailer tongue (A) should weigh 12 percent of the total loaded trailer weight (B). Hitches After you’ve loaded your trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they aren’t, you may be able to get them right simply by moving some items around in the trailer.
yellowblue Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. Follow the manufacturer’s recommendation for attaching safety chains and do not attach them to the bumper.
yellowblue During your trip, check occasionally to be sure that the load is secure, and that the lamps and any trailer brakes are still working. 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. Making Turns NOTICE: Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. Your vehicle could be damaged.
yellowblue Driving On Grades Parking on Hills 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 AUTOMATIC OVERDRIVE ( ). 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).
yellowblue 5. If you have a four-wheel-drive vehicle, be sure the transfer case is in a drive gear and not in NEUTRAL (N). 6. Release the regular brakes. CAUTION: It can be 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. If you have left the engine running, the vehicle can move suddenly. You or others could be injured.
yellowblue Trailer Wiring Harness A. Light-Duty Wiring Harness B. Additional Heavy-Duty Wiring C. Tie Straps An eight-wire harness is stored under the rear end of your vehicle. Five wires (A) are located between the rear bumper and the spare tire, near the center. This wiring harness is tie-strapped to the taillamp and stoplamp harness. Three wires (B) (light gauge white, blue and orange) are located at the rear left hand frame rail.
yellowblue Power Winches If you wish to use a power winch on your vehicle, only use it when your vehicle is stationary or anchored. Power Take-Off (PTO) (Manual Transmission) NOTICE: 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). Use the regular brakes, set the parking brake, or block the wheels to keep your vehicle from rolling.

yellowblue ✍ 4-64 NOTES
yellowblue Section 5 Problems on the Road Here you’ll find what to do about some problems that can occur on the road.
yellowblue Hazard Warning Flashers Press the button at the top of the steering column all the way down to make your front and rear turn signal lamps flash on and off. Your hazard warning flashers work no matter what position your key is in, and even if the key isn’t in. To turn off the flashers, press the button until the first click and release. 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.
yellowblue Other Warning Devices If you carry reflective triangles, you can use them to warn others. Set one up at the side of the road about 300 feet (100 m) behind your vehicle. Jump Starting If your battery (or batteries) have run down, you may want to use another vehicle and some jumper cables to start your vehicle. But please use the following steps to do it safely. CAUTION: Batteries can hurt you. They can be dangerous because: D They contain acid that can burn you.
yellowblue 2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles aren’t touching each other. If they are, it could cause a ground connection you don’t want. You wouldn’t be able to start your vehicle, and the bad grounding could damage the electrical systems. To avoid the possibility of the vehicles rolling, set the parking brake firmly on both vehicles involved in the jump start procedure. Put an automatic transmission in PARK (P) or a manual transmission in NEUTRAL (N).
yellowblue CAUTION: Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. Be sure the batteries have enough water. You don’t need to add water to the ACDelco FreedomR battery (or batteries) installed in every new GM vehicle. But if a battery has filler caps, be sure the right amount of fluid is there. If it is low, add water to take care of that first.
yellowblue 7. Don’t let the other end touch metal. Connect it to the positive (+) terminal of the good battery. 6. Connect the red positive (+) cable to the positive (+) terminal of the vehicle with the dead battery. 8. Now connect the black negative (-) cable to the good battery’s negative (-) cable. 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.
yellowblue 12. Remove the cables in reverse order to prevent electrical shorting. Take care that they don’t touch each other or any other metal. 9. Attach the cable at least 18 inches (45 cm) away from the dead battery, but not near engine parts that move. The electrical connection is just as good there, but the chance of sparks getting back to the battery is much less. 10. Now start the vehicle with the good battery and run the engine for awhile. A. Heavy Metal Engine Part B. Good Battery C.
yellowblue Towing Your Vehicle CAUTION: To help avoid serious personal injury to you or others: D Never let passengers ride in a vehicle that is being towed. D Never tow faster than safe or posted speeds. D Never tow with damaged parts not fully secured. D Never get under your vehicle after it has been lifted by the tow truck. D Always secure the vehicle on each side with separate safety chains when towing it. D Use only the correct hooks.
yellowblue Engine Overheating (Gasoline Engine) You will find a coolant temperature gage on your vehicle’s instrument panel. See “Engine Coolant Temperature Gage” in the Index. If your vehicle has a diesel engine, see “Engine Overheating” in the Diesel Engine Supplement. If Steam Is Coming From Your Engine CAUTION: Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it.
yellowblue If No Steam Is Coming From Your Engine If you get an engine overheat warning 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. If you get the overheat warning with no sign of steam, try this for a minute or so: 1. If you have an air conditioner and it’s on, turn it off.
yellowblue Cooling System (Gasoline Engine) When you decide it’s safe to lift the hood, here’s what you’ll see: CAUTION: If your vehicle has air conditioning, the auxiliary electric engine cooling fan under the hood can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan. If the coolant inside the coolant recovery tank is boiling, don’t do anything else until it cools down. A. Coolant Recovery Tank B.
yellowblue The coolant level should be at or above the COLD mark. If it isn’t, you may have a leak 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.
yellowblue How to Add Coolant to the Coolant Recovery Tank (Gasoline Engines) NOTICE: If you haven’t found a problem yet, but the coolant level isn’t at or above the COLD mark, add a 50/50 mixture of clean, drinkable water and DEX-COOLR engine coolant at the coolant recovery tank. (See “Engine Coolant” in the Index for more information.) In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. Use the recommended coolant and the proper coolant mixture.
yellowblue CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Don’t spill coolant on a hot engine. When the coolant in the coolant recovery tank is at or above the COLD mark, start your vehicle. If the overheat warning continues, there’s one more thing you can try. You can add the proper coolant mixture directly to the radiator, but be sure the cooling system is cool before you do it.
yellowblue 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 radiator pressure cap -- even a little -- they can come out at high speed. Never turn the cap when the cooling system, including the radiator pressure cap, is hot. Wait for the cooling system and radiator pressure cap to cool if you ever have to turn the pressure cap.
yellowblue How to Add Coolant to the Radiator 2. Then keep turning the pressure cap, but now push down as you turn it. Remove the pressure cap. 1. You can remove the radiator pressure cap when the cooling system, including the radiator pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise until it first stops. (Don’t press down while turning the pressure cap.) If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left.
yellowblue 3. Fill the radiator with the proper DEX-COOLR coolant mixture, up to the base of the filler neck. (See “Engine Coolant” in the Index for more information about the proper coolant mixture.) 4. Then fill the coolant recovery tank to the COLD mark. 5. Put the cap back on the coolant recovery tank, but leave the radiator pressure cap off.
yellowblue 6. Start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan(s). 7. By this time, the coolant level inside the radiator filler neck may be lower. If the level is lower, add more of the proper DEX-COOLR coolant mixture through the filler neck until the level reaches the base of the filler neck. 5-18 8. Then replace the pressure cap.
yellowblue 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.
yellowblue 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: Changing a tire can cause an injury. The vehicle can slip off the jack and roll over you or other people. You and they could be badly injured. Find a level place to change your tire. To help prevent the vehicle from moving: 1. Set the parking brake firmly. 2.
yellowblue Removing the Spare Tire and Tools Extended Cab Models 2 and 4-Door Models The equipment you’ll need is behind the passenger’s seat. Turn the wing nut counterclockwise and remove the jack cover, if there is one. Remove the jacking equipment. If you have a chassis cab, refer to the information from the body supplier/installer for the location of your spare tire. You’ll use the jack handle and the ratchet to remove an underbody-mounted spare tire.
yellowblue Follow these instructions to lower the spare tire: 1. One side of the ratchet has an UP marking. The other side has a DOWN marking. Assemble the ratchet to the hook near the end of the jack handle (as illustrated) with the DOWN marking facing you. Insert the other end through the hole in the rear bumper and into the hoist shaft. 2. Turn the ratchet to lower the spare tire to the ground. Continue to turn the ratchet until the spare tire can be pulled out from under the vehicle. 3.
yellowblue The tools you’ll be using include the jack (A), the jack handle extension (B), the jack handle (C), the wheel wrench (D) and the ratchet (E). Attach the jack handle (and jack handle extension, if needed) to the jack. If the flat tire is on the rear of the vehicle, you’ll need the jack handle extension also.
yellowblue If your vehicle has wheel nut caps, use the wheel wrench and ratchet to remove them. Turn the wheel wrench counterclockwise, with DOWN facing you, to remove the wheel nut caps. Then take off the hub cap. With the UP marking on the ratchet facing you, rotate the ratchet clockwise. That will lift the jack head a little. If the wheel also has a trim ring, use the wheel wrench to pry along the edge and remove it.
yellowblue Removing the Flat Tire and Installing the Spare Tire 1. Use the ratchet and wheel wrench to loosen all the wheel nuts. Turn the wheel wrench counterclockwise, with DOWN facing you, to loosen the wheel nuts. Don’t remove the wheel nuts yet. 2. Position the jack under the vehicle. If the flat tire is on the front of the vehicle, position the jack on the frame behind the flat tire. If the flat tire is on the rear, position the jack on the rear axle between the spring and the shock absorber.
yellowblue 4. Remove all the wheel nuts and take off the flat tire. Front Position Rear Position 3. With UP on the ratchet facing you, raise the vehicle by rotating the ratchet and wheel wrench clockwise. Raise the vehicle far enough off the ground so there is enough room for the spare tire to fit. 5-26 5. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel.
yellowblue 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. 6.
yellowblue 8. Tighten the nuts firmly in a crisscross sequence as shown by rotating the wheel wrench clockwise. Front Position Rear Position 7. Lower the vehicle by rotating the ratchet and wheel wrench counterclockwise. Lower the jack completely. 5-28 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.
yellowblue NOTICE: Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification. 9. Put the wheel trim back on. For vehicles with plastic wheel nut caps, tighten the caps until they are finger-tight, then tighten them an additional one-half of a turn with the ratchet and wheel wrench.
yellowblue For an underbody spare tire carrier, store the tire under the rear of the vehicle in the spare tire carrier. To store the tire: 1. Put the tire on the ground at the rear of the vehicle with the valve stem pointed down 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 ratchet, with the UP mark facing you, near the hook at the end of the jack handle.

yellowblue NOTICE: Using the Recovery Hooks 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.
yellowblue CAUTION: The recovery 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.

yellowblue 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.
yellowblue 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.
yellowblue 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.
yellowblue If you’re using fuel rated at 87 octane or higher and you hear heavy knocking, your engine needs service. But don’t worry if you hear a little pinging noise when you’re accelerating or driving up a hill. That’s normal, and you don’t have to buy a higher octane fuel to get rid of pinging. It’s the heavy, constant knock that means you have a problem.
yellowblue NOTICE: Your vehicle was not designed for fuel that contains methanol. Don’t use it. It can corrode metal parts in your fuel system and also damage plastic and rubber parts. That damage wouldn’t be covered under your warranty. Fuels in Foreign Countries (Gasoline Engines) You can also write us at the following address for advice. Just tell us where you’re going and give your Vehicle Identification Number (VIN).
yellowblue The fuel cap is located on the driver’s side of your vehicle. Refuel the front tank first on a chassis-cab model, or in instances when only a partial fuel fill is desired. An automatic transfer mechanism will maintain approximately equal fuel levels in both tanks, so no switching is required by the operator. 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.
yellowblue 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 filler cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel filler 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.
yellowblue 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.
yellowblue Hood Release To open the hood, first pull the handle inside the vehicle. Then go to the front of the vehicle and pull up on the secondary hood release, located just to the passenger’s side of the center of the grill. Lift the hood. Before closing the hood, be sure all filler caps are on properly. Pull down the hood and close it firmly.

yellowblue 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.
yellowblue Among those acts presumed to constitute tampering are the acts listed below. Insulation: D Removal of the noise shields or any underhood insulation. Engine: Engine Oil (Gasoline Engine) If your vehicle has a diesel engine, see “Engine Oil (Diesel Engine)” in the Diesel Engine Supplement. It’s a good idea to check your engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground.
yellowblue Checking Engine Oil 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 upper mark that shows the proper operating range, your engine could be damaged. The engine oil fill cap for the “VORTEC” 5000 and 5700 V8 engine is located on the driver’s side engine valve cover.
yellowblue 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. If you change your own oil, be sure you use oil that has the Starburst symbol on the front of the oil container.
yellowblue As shown in the chart, 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.
yellowblue If none of them is true, use the long trip/highway maintenance schedule. Change the oil and filter every 7,500 miles (12 500 km) or 12 months -- whichever occurs first. Driving a vehicle with a fully warmed engine under highway conditions causes engine oil to break down slower.
yellowblue The air cleaner assembly has an indicator that lets you know when the air filter is dirty and needs to be serviced. The indicator is located in the air intake tube between the air cleaner and the engine. See “Owner Checks and Services” in the Index to determine when to check the indicator. If the area inside the clear section of the indicator is green, no air filter service is required. When the area inside the indicator is orange and CHANGE AIR FILTER appears, the filter should be replaced.
yellowblue 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. Install the cover and fasten the two retaining clips. After the air filter is properly serviced, the indicator should be reset.
yellowblue Automatic Transmission Fluid How to Check If your vehicle has a diesel engine, see “Automatic Transmission Fluid” in the Diesel Supplement. Because this operation can be a little difficult, you may choose to have this done at the GM service department. When to Check and Change If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick. A good time to check your automatic transmission fluid level is when the engine oil is changed.
yellowblue To get the right reading, the fluid should be at normal operating temperature, which is 180_F to 200_F (82_C to 93_C). Checking the Fluid Level Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above 50_F (10_C). If it’s colder than 50_F (10_C), drive the vehicle in THIRD (3) until the engine temperature gage moves and then remains steady for 10 minutes. Then follow the hot check procedures.
yellowblue Then, without shutting off the engine, follow these steps: 3. Check both sides of the dipstick, and read the lower level. The fluid level must be in the COLD area for a cold check or in the HOT area or cross-hatched area for a hot check. 1. The red transmission dipstick handle is located at the rear of the engine compartment, on the passenger’s side. Flip the handle up and then pull out the dipstick and wipe it with a clean rag or paper towel. 2.
yellowblue How to Add Fluid Manual Transmission Fluid Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See “Recommended Fluids and Lubricants” in the Index. When to Check 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).
yellowblue Check the fluid level only when your engine is off, the vehicle is parked on a level place and the transmission is cool enough for you to rest your fingers on the transmission case. 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.
yellowblue When to Check and What to Use How to Check Lubricant Refer to the Maintenance Schedule to determine how often you should check the fluid level in your clutch master cylinder reservoir and for the proper fluid. See “Owner Checks and Services” and “Recommended Fluids and Lubricants” in the Index. How to Check The proper fluid should be added if the level does not reach the bottom of the diaphragm when it’s in place in the reservoir. See the instructions on the reservoir cap.
yellowblue C3 (3500 HD) Trucks Equipped with Dana Rear Axle How to Check Lubricant Additional rear axle scheduled maintenance is required on 3500 HD models equipped with Dana rear axles when they are driven under the following conditions: D Extreme loading (at or near GVWR) or trailer towing, and: D Operation above 45 mph (70 km/h) for extended periods of time Vehicles used in any of these conditions require the rear axle lubricant be changed every 30,000 miles (50 000 km). Fluid capacity is 4.
yellowblue Front Axle When to Check and Change Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant and when to change it. See “Scheduled Maintenance Services” in the Index. How to Check Lubricant When the differential is at operating temperature (warm), add enough lubricant to raise the level to the bottom of the filler plug hole. What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use.
yellowblue The radiator pressure cap must be tightly installed with the arrows on the cap lined up with the overflow tube on the radiator filler neck. NOTICE: Your radiator 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. Be sure the arrows on the cap line up with the overflow tube on the radiator filler neck. Thermostat Engine coolant temperature is controlled by a thermostat in the engine coolant system.
yellowblue NOTICE: When adding coolant, it is important that you use only DEX-COOLR (silicate-free) coolant. If coolant other than DEX-COOL is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner -- at 30,000 miles (50 000 km) or 24 months, whichever occurs first. Damage caused by the use of coolant other than DEX-COOLR is not covered by your new vehicle warranty.
yellowblue NOTICE: Checking Coolant If you use an improper coolant mixture, your engine could overheat and be badly damaged. The repair cost wouldn’t be covered by your warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core and other parts. If you have to add coolant more than four times a year, have your dealer check your cooling system. NOTICE: If you use the proper coolant, you don’t have to add extra inhibitors or additives which claim to improve the system.
yellowblue Adding Coolant If you need more coolant, add the proper DEX-COOLR Add coolant mixture at the recovery tank, but be careful not to spill it. coolant mixture at the coolant recovery tank. CAUTION: CAUTION: Turning the radiator pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. With the coolant recovery tank, you will almost never have to add coolant at the radiator.
yellowblue Power Steering Fluid How To Check Power Steering Fluid When the engine compartment is cool, wipe the cap and the top of the reservoir clean, then unscrew the cap and wipe the dipstick with a clean rag. Replace the cap and completely tighten it. Then remove the cap again and look at the fluid level on the dipstick. The level should be at the FULL COLD mark. If necessary, add only enough fluid to bring the level up to the mark.
yellowblue Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure to read the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing. NOTICE: D When using concentrated washer fluid, D Adding Washer Fluid D D follow the manufacturer’s instructions for adding water. Don’t mix water with ready-to-use washer fluid.
yellowblue Brakes Brake Fluid Your brake master cylinder reservoir is here. It is filled with DOT-3 brake fluid. 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. CAUTION: If you have too much brake fluid, it can spill on the engine.
yellowblue Checking Brake Fluid 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. 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: You can check the brake fluid without taking off the cap.
yellowblue NOTICE: D Using the wrong fluid can badly damage D brake system parts. For example, just a few drops of mineral-based oil, such as engine oil, in your brake system can damage brake system parts so badly that they’ll have to be replaced. Don’t let someone put in the wrong kind of fluid. If you spill brake fluid on your vehicle’s painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately.
yellowblue NOTICE: Brake linings should always be replaced as complete axle sets. Continuing to drive with worn-out brake pads could result in costly brake repair. See “Brake System Inspection” in Section 7 of this manual under Part C “Periodic Maintenance Inspections.” 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.
yellowblue Replacing Brake System Parts Vehicle Storage 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 have to have new ones put in -- be sure you get new approved GM replacement parts.

See “Wiper Blade Check” in Section 7 of this manual under Part B “Owner Checks and Services” 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. Here’s how to remove the Shephard’s Hook type. To replace the windshield wiper blade assembly: 1.
yellowblue 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. 6-50 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. See “Loading Your Vehicle” in the Index.
yellowblue Inflation -- Tire Pressure The Certification/Tire label, which is on the rear edge of the driver’s door, or on the incomplete vehicle document in the cab, 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.
yellowblue When to Check Check your tires once a month or more. Also, check the tire pressure of the spare tire. How to Check The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See “Scheduled Maintenance Services” in the Index for scheduled rotation intervals. Use a good quality pocket-type gage to check tire pressure. You can’t tell if your tires are properly inflated simply by looking at them.
yellowblue If your vehicle has dual rear wheels and the load range or tread design for your front tires is different from your rear tires, always use the correct rotation pattern shown here when rotating your tires. If your vehicle has dual rear wheels and the load range and tread design for your front tires is the same as your rear tires, always use one of the correct rotation patterns shown here when rotating your tires.
yellowblue When It’s Time for New Tires CAUTION: Rust or dirt on a wheel, or on the parts to which it is fastened, can make 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 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.
yellowblue Dual Tire Operation When the vehicle is new, or whenever a wheel, wheel bolt or wheel nut is replaced, 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. The outer tire on a dual wheel setup generally wears faster than the inner tire. Your tires will wear more evenly and last longer if you rotate the tires periodically.
yellowblue If you ever replace your tires with those not having a TPC Spec number, make sure they are the same size, load range, speed rating and construction type (bias, bias-belted or radial) as your original tires. CAUTION: Mixing tires could cause you to lose control while driving. If you mix tires of different sizes or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes may also cause damage to your vehicle.
yellowblue Treadwear Temperature -- A, B, C 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.
yellowblue Wheel Alignment and Tire Balance The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. Scheduled wheel alignment and wheel balancing are not needed. However, if you notice unusual tire wear or your vehicle pulling one way or the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalanced.
yellowblue 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.
yellowblue Tire Chains NOTICE: If your vehicle has dual wheels, P265/75R16 or LT265/75R16 size tires, don’t use tire chains. They can damage your vehicle because there’s not enough clearance. Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination and road conditions. Follow that manufacturer’s instructions.
yellowblue 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.
yellowblue D Use a clean cloth or sponge, and change to a Special Fabric Cleaning Problems D If a ring forms on fabric after spot cleaning, clean the Stains caused by such things as catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, vomit, urine and blood can be removed as follows: clean area often. A soft brush may be used if stains are stubborn. entire area immediately or it will set. Using Multi-Purpose Interior Cleaner on Fabric 1.
yellowblue Fabric Protection Cleaning Leather Your vehicle has upholstery and carpet that has been treated with Scotchgardt Fabric Protector, a 3M product. It protects fabrics by repelling oil and water, which are the carriers of most stains. Even with this protection, you still need to clean your upholstery and carpet often to keep it looking new. Use a soft cloth with lukewarm water and a mild soap or saddle soap and wipe dry with a soft cloth. Then, let the leather dry naturally.
yellowblue Care of Safety Belts Keep belts clean and dry. CAUTION: Do not bleach or dye safety belts. If you do, it may severely weaken them. In a crash, they might not be able to provide adequate protection. Clean safety belts only with mild soap and lukewarm water. Cleaning Glass Surfaces 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.
yellowblue Cleaning the Outside of Your Vehicle Cleaning Exterior Lamps/Lenses The paint finish on your vehicle provides beauty, depth of color, gloss retention and durability. Use lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses. Follow instructions under “Washing Your Vehicle.” Washing Your Vehicle The best way to preserve your vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water.
yellowblue Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage your vehicle’s finish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non-abrasive cleaners that are marked safe for painted surfaces to remove foreign matter.
yellowblue Cleaning Tires Underbody Maintenance To clean your tires, use a stiff brush with a tire cleaner. Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, accelerated corrosion (rust) can occur on the underbody parts such as fuel lines, frame, floor pan and exhaust system even though they have corrosion protection. At least every spring, flush these materials from the underbody with plain water.

yellowblue 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.
yellowblue 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.
yellowblue CAUTION: Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, you can be seriously injured. Do your own maintenance work only if you have the required know-how and the proper tools and equipment for the job. If you have any doubt, have a qualified technician do the work. If you are skilled enough to do some work on your vehicle, you will probably want to get the service information. See “Service and Owner Publications” in the Index.
yellowblue 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.
