Head Restraints d the top of your ears. This position reduces the chanceof a neck injury in a crash. Seatback Latches(Full Bench Seat) The front seatback folds forward to let you access the rear of the cab. Your seatback will move back and forth freely, unless you come to a sudden stop. Then it will lock inplace. If you have a Crew Cab, your front seatback isdesigned not to fold forward. Access to the rear of the cab is available by using the rear doors.
After returning the seatback to its upright position, pull the seatback forward to make sure it is locked. Seatback Latches (Reclining Split Bench and Reclining Bucket Seafs) The front seatback folds forward to let you access the rear of thecab. To fold the seatback forward, lift this lever. Lift the frontof the lever and the seatback will fold forward. To return the seatback to the upright position, push the seatback rearward until it latches.

Your seatback will move back andforth freely, unless you come to a sudden stop.
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. This figure lights up as a reminder to buckle up. (See “Safety Belt Reminder Light” in the Index.) It will light whenyou turn the key to RUN or START when your safety belt isn’t buckled, and you’ll heara tone or buzzer, too. In many states and Canadian provinces, the lawsays t o wear safety belts. Here’s why: They work.
A few crashes are mild, and some crashes can beso serious that even buckled up aperson wouldn’t survive. But most crashes are in between. In many of them, people who buckle up can surviveand sometimes walk away. Without belts they could have been badly hurt or killed. After more than 25 years of safety belts in vehicles, the facts are clear. In most crashes bucklingup does matter... a lot! Why Safety Belts Work When you ride in or on anything, you go as fast as it goes.
When the bike hits the block, it stops. But the child keeps going! Take the simplest “vehicle.” Suppose it’s just a seat on wheels. Put someone on it.
3 Get it up to speed. Then stop the “vehicle.” The rider doesn’t stop. The person keeps going until stopped by something. In a real vehicle, it could be the windshield ... or the instrument panel ...
or the safety belts i With safety belts, you slow down as the vehicledoes. You get more time to stop. You stop over more distance, and yourstrongest bones take the forces. That’s why safety belts make such good sense. Here Are Questions Many People Ask About Safety Belts- and the Answers Q: Won’t I be trapped in the vehicle after an accident ifI’m wearing a safety belt? A: You could be - whether you’re wearing a safety belt or not. But you can easily unbuckle a safety belt, even if you’re upside down.
Q : If I ’rn a good driver, and I never drive farjrom home, why shouldI 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). Safety belts are for everyone.
Driver Position This section describes the driver’s restraint system. Lap-Shoulder Belt The driver has a lap-shoulder belt. Here’s how to wear it properly. 1. Close and lock the door. 2. Adjust the seat (to see how, see “Seats” in the Index) so you can sit up straight.
3. Pick up the latch plate and pull the belt across you. (On some models, you may hear a clickingsound as the belt is pulled out. The clicking sound is the shoulderbelt tension feature operatingproperly.) Don’t let the belt get twisted. 4. Push the latchplate into the buckleuntil 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.
Q: What’s wrong with this? A: The shoulder belt is too loose. It won’t give nearly as much protection this way.
Q: What’s wrong with this? A: The belt is buckled in the wrong place.
Q: What’s wrong with this? A: The belt is over an armrest.
Q: What's wrong with this? A: The shoulder belt is worn under the arm. It should be worn over the shoulder at all times.
Q: What's wrong with this? L A: I I I I I I 1 1 I I I The belt is twisted across the body. 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.
Safety Belt Use During Pregnancy The bestway to protect the fetus is protect to the mother. When a safety belt is worn properly, it’s more likely that the fetus won’t be hurt in acrash. For pregnant women, as for anyone,the key to making safety belts effective is wearing them properly. Right Front Passenger Position The right front passenger’s safety belt works the same way as the driver’s safety belt. See “DriverPosition,” earlier in this part.
Center Passenger Position Lap Belt If your vehicle has front and rear bench seats, someone can sit in the center positions. 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.
To make the belt shorter, pull its free end as shown until the belt is snug. I Buckle, position and release it the same wayas the lap part of a lapshoulder belt. If the belt isn’t long enough, see “Safety Belt Extender” atthe end of this section. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quicklyif you ever had to.
Lap-Shoulder Belt The positions next to the windows have lap-shoulder belts. Here’s how to wear one properly. L 1. Pick up the latch plate and pullthe belt across you. (On some models, you may hear a clicking sound as the belt is pulled out. The clicking sound is the shoulder belt tension feature operating properly.) Don’t let the belt get twisted. 2. Push the latch plate into the buckle until it clicks.
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 andsnug 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.
Rear Seat Outside PassengerPositions (Crew Cab) Lap-Shoulder Belt belts. Here ’s how to 1. Pick up the latch plate and pull the belt across you. (On some models, you may hear a clicking sound as the belt is pulled out. The clicking sound is the shoulder belt tension feature operating properly.) Don’t let the belt 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. When the lap beltis pulled out all the way, it will lock.
The lap part of the belt should be worn lowand snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvicbones. 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. These parts of the body are best able to take belt restraining forces.
Children Everyone in a vehicle needs protection! That includes infants and all children smaller than adult size. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle.
1-31
Child Restraints Be sureto follow the instructions for the restraint. You may find these instructions on the restraint itself or in abooklet, or both. These restraints use the belt system in your vehicle, but the child also has to besecured within the restraint to help reduce the chance of personal injury. The instructions that come with the infant or child restraint will show you how to do that.
If you need to have an anchor installed, you can ask your dealer to put it in for you. If you want to install an anchoryourself, your dealer cantell you how to do it.

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 beready to work for an adult or larger child passenger.
Larger Children Children who have outgrown child restraints should we.ar the vehicle’s safety belts. If you have the choice, a child should sit nextto 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. a Children who aren’t buckled up can be thrown out in a crash.
A: Move the child toward the center of the vehicle, but be sure that the shoulder belt still is on the child’s shoulder, so that in a crash the If the child’s upper body would have the restraint that belts provide. child is so small that the shoulder belt is still very close to the child’s face orneck, you might want to place the childin a seat that has a lap belt, if your vehicle has one.
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. This applies belt force to the child’s pelvic bones in a crash. Safety Belt Extender If the vehicle’s safety belt will fasten around you, you should useit. 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.
Checking Your Restraint Systems Now and then, make sure all your belts, buckles, latch plates, retractors, anchorages and reminder systems are working properly.Look for any loose parts or damage. If you see anything that might keepa restraint system from doing its job, have it repaired. Replacing Safety Belts After a Crash If you’ve had a crash, do you need new belts? After a very minor collision, nothing may be necessary.
A 1-45 The model number on the replacement belt must be listed on the safety belt you want to replace. Pull the shoulder belt all the way out to see this label.

Defensive Driving The best advice anyonecan give about driving is: Drive defensively. Please start with a very important safety device in your Vehicle: Buckle up. (See “Safety Belts” in the Index.) 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. Beready for their mistakes.
According to the American Medical Association, a 180-pound (82 kg) person who drinks three 12-ounce (355 ml) bottles of beer in an hour will end up with a BAC of about 0.06 percent. The person would reach the same BAC by drinking three 4-ounce (120 ml) glasses of wine or three mixed drinks if each had 1-1/2 ounces (45 ml) of a liquor like whiskey, gin or vodka. It's the amount of alcohol that counts.
But it’s very important to keep in mind that the ability to drive is affected well below a BAC of 0. I0 percent. Research shows that the driving skills of many people are impaired at a BAC approaching 0.05 percent, and that the effects are worse at night. All drivers are impaired at BAC levels above 0.05 percent. Statistics show that the chance of being in an accident increases sharply for drivers who have a BAC of 0.05 percent or above. A driver with a BAC level of 0.
Control of a Vehicle You have three systems that make your vehicle go where you want it to go. They are the brakes, the steering and the accelerator. All three systems have to do their work at the places where the tires meet the road. Sometimes, as when you’re driving on snow or ice, it‘s easy to ask more of those control systems than the tires and road can provide. That means you can lose control of your vehicle. Braking Braking action involves perceptiorz time and renction time.
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 an advanced electronic braking system that can help you keep it under control.
I- . , As you brake, your computer keeps receiving updates on rear wheel speed and controls braking pressureaccordingly. Remember: Anti-lock doesn't change the time you need to get your foot up to the brake pedal. If you get too close tothe vehicle in front of you, you won't have time toapply your brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have anti-lock brakes. To Use Anti-Lock Use rear-wheel anti-lock like regular brakes.
So, use a “squeeze” braking technique. This will give you maximum braking while maintaining steering control. You do this by pushing on the brake pedal with steadily increasing pressure. When you do, it will help maintain steering control. In many emergencies, steering can help you more than even the very best braking. 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.
If you need to reduce your speed as you approach a curve, do it before you enter the curve, while your front wheels are straight ahead. Try to adjust your speed so you can “drive” through the curve. Maintain a reasonable, steady speed. Wait to accelerate until you are out of the curve. and then accelerate gently into the straightaway. steering in Emergencies There are timeswhen steering can be more effective than braking.
Off-Road Recovery You may find sometime that your right wheels have dropped off the edge of a road onto the shoulder while you’re driving. If the level of the shoulder is only slightly below the pavement, recovery should be fairly easy. Ease off the accelerator and then, if there is nothing in the way, steer so that your vehicle straddles the edge of the pavement. You can turn the steering wheel up to 1/4 turn until the right front tire contacts the pavement edge.
0 Watch for traffic signs, pavement markings, and lines. If you can see a sign up ahead that might indicate a turn or an intersection, delay your pass. A broken center line usually indicates it’s all right to pass (providing the road ahead is clear). Never cross a solid line on your side of the lane or a double solid line, even if the road seems empty of approaching traffic. 0 Do not get too closeto the vehicle you want to pass while you’re awaiting an opportunity.
Skidding In a skid, adriver can lose control of the vehicle. Defensive drivers avoid most skids by taking reasonable care suited to existing conditions, and by not “overdriving” those conditions. But skids are always possible. The three types of skids correspond to your Vehicle’s three control systems. In the braking skid your wheels aren’t rolling. In the steering or cornering skid, too much speed or steering in a curve causes tires to slip and lose cornering force.
Driving Guidelines 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 driveoff-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.
You’ll find other important information in this manual. See “Vehicle Loading,” “Luggage Carrier’’ and “Tires” in the Index. 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.
Controlling your vehicleis the key to successful off-road driving. Oneof the best ways to control your vehicle is to control your speed. Here are some things to keep in mind. At higher speeds: you approach things faster and you have less time to scan the terrain for obstacles. 0 you have less time to react. 0 you have more vehicle bounce when you drive over obstacles. you’ll need more distancefor braking, especially since you’re on an unpaved surface.
When you drive over obstacles or rough terrain, keep a firm grip on the steering wheel. Ruts, troughs, or other surface features can jerk the wheel out of your hands if you’re not prepared. When you drive overbumps, rocks, or other obstacles, your wheels can leave the ground. If this happens, even with one or two wheels, you can’t control the vehicle as well or at all. Because you will be on an unpaved surface, it’s especially important to avoid sudden acceleration, sudden turns. or sudden braking.
Here are some otherthings to consider as you approach a hill.
Q: What should I do if my vehicle stalls, or is about to stall, andI can’t makeit up the hill? A: 0 If this happens, there are some things you should do, and there are some things you must not do. First, here’s what you slzould do: Push the brake pedal to stop the vehicle and keep it from rolling backwards. Also, apply the parking brake. a If your engine is still running, shift the transmission into reverse, release the parking brake, and slowly back down the hill in reverse.
Instead, apply the regular brake to stop the vehicle. Then apply the parking brake. Shift into reverse, release the parking brake, and slowly back straight down. Never attempt toturn around if you are about to stall when going up a hill. If the hill is steep enough to stall your vehicle, it’s steep enough to cause you to roll over if you turn around. If you can’t make it up the hill, you must back straight down the hill. Q: Suppose, after stalling, I try to back down the hill and decideI just can’t do it.
If you decide you can go down a hill safely, then try to keep your vehicle headed straight down, and use a low gear. This way, engine drag can help your brakes and they won’t have to do all the work. Descend slowly, keeping your vehicle under control at all times. A CAUTION: Heavy braking when going downa hill can cause your brakes to overheat and fade. This could cause loss of control and a serious accident.
Driving Across an Incline Sooner orlater, an off-road trail will probably go across the incline of a hill. If this happens, you have to decide whether to try to drive across the incline. Here are some things to consider: 0 A hill that can be driven straighr: upor aown may be too steep to drive across. When you go straight up or down a hill, the length of the wheel base (the distance fromthe front wheels tothe rear wheels) reduces the likelihood the vehicle will tumble end over end.
Stalling on an Incline If your vehicle stalls when you’re crossing an incline, be sure you (and your passengers) get out on the uphill side, even if the door there is harder to open. If you get out on the downhill side and the vehicle starts toroll over, you’ll be right in its path. If you have to walk down the slope, stay out of the path the vehicle will take if it does roll over. Driving In Mud, Sand, Snow, Or Ice When you drive in mud, snow or sand, your wheels won’t get good traction.
Hard packed snow and ice offer the worst tire traction. On these surfxes, it’s very easy to lose control. On wet ice, for example, the traction is so poor that you will have difficulty accelerating. And if you do get moving, poor steering and difficult braking can cause you to slide out of control. 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.
After Off-Road Driving Remove any brush or debris that has collected on the underbody, chassis or under the hood. These accumulations can be a fire hazard. After operation in mud or sand, have the brake linings cleaned and checked. These substances can cause glazing and uneven braking. Check the body structure, steering, suspension,wheels, tires, and exhaust system for damage. Also, check the fuel lines and cooling system for any leakage. Your vehicle will require more frequent service due to off-road use.
Nighf Vision No one can see as well at night as in the daytime. But as we get older these differences increase. A50-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 i n 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.
Driving in the Rain 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 wiseto 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.
Driving toofast through large water puddles or even going through some too. The water may affect your brakes. Try car washes can cause problems, to avoid puddles. Butif you can’t, try to slow down before you hit them. Hydroplaning Hjdroplaning is dangerous. So much water can build up under your tires that they can actuallyride on the water. Thiscaa happen if the roadis wet is hydroplaning, it enough and you’re goingfast enough. When your vehicle has little or no contact with the road.
Some Other Rainy Weather Tips 0 Turn on your low-beam headlights - not just your parking llgnts - to help make you more visible to others. Besides slowing down, allow some extra following distance. And be especially careful when you pass another vehicle. Allow yourself more clear room ahead, and be prepared to have your view restricted by road spray. Have good tires with proper tread depth. (See “Tires” in the Index.
Freeway Driving Mile for mile, freeways (also called thruways, parkways, expressways, turnpikes, or superhighways) are the safest of all roads. But they have their own special rules. The most important advice on freeway driving is: Keep up with traffic and keep to the right. Drive at the same speed most of the other drivers are driving. Too-fat or too-slow driving breaks a smooth traffic flow. Treat the left lane on a freeway as a passing lane.
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’reready. 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. Wear comfortable clothing and shoes you can easily drive in.
What can you do about highway hypnosis? First, be awarethat it can happen. Then here are some tips: 0 Make sure yourvehicle is well ventilated, with a comfortably cool interior. Keep your eyes moving. Scanthe road ahead and to the sides. Check your mirrors and your instruments frequently. 0 If you get sleepy, pull off the road into a rest, service, or parking area and take a nap, get some exercise, or both. For safety, treat drowsiness on the highway as an emergency.
Know how to go uphill. You may want to shift down to a lower gear. The lower gears help cool your engine and , and you can climb the hill better. Stay in your own lane when driving on two-lane roads in hills or mountains. Don’t swing wide or cut across the center of the road. Drive at speeds that let you stay in your own lane. As you go over the top of a hill, be alert. There could be something in your lane, like a stalled car or an accident.
Winter Driving Here are some tips for winter driving: Have your Vehicle in good shape for winter. Be sure your engine coolant mix is correct. 0 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 a coupleof reflective warning triangles.
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 theleast traction of all. You can get “wet ice” when it’s about freezing (32”F; 0°C) and freezing rain begins to fall. Try to avoid driving on wet ice until salt and sand crews can get there. Whatever the condition - smooth ice, packed, blowing or loose snowdrive with caution. Accelerate gently. Try not to break the fragile traction.
If You’re Caughtin a Blizzard 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 thesnow. Here are some thingsto do to summon help and keep yourself and your passengers safe: Turn on your hazard flashers. Tie a red cloth to your vehicle to alert police that you’ve been stopped by the snow,Put on extra clothingor wrap a blanket around you.
I Run your engine only as long as you must. This saves fuel.When you run the engine, make it go a little faster than just idle. That is, push the accelerator slightly. This uses less fuel for the heat that you get and it keeps the battery (or batteries) charged. You will need a well-charged battery (or batteries) to restart the vehicle, and possibly for signaling later on with your headlights. Let the heater run for awhile.
Power Take-Off (PTO) NOTICE: If you willbe using the PTO while the vehicle remains in one place, drive thevehicle to warm it up before operating thePTO. Don’t use the PTO for more than four hourswithout driving your vehicle again. If you don’t followthese guidelines, your transfer case or transmission could be damaged. NOTICE: Don’t have a PTO that will exceed 35 horsepower installed on your vehicle. It could damage your transmissionor transfer case.
If you are going to drive the vehicle, shift the transmission into the gear you want. Then shiftthe transfer case into the range you want, apply the regular brakes and release the parking brake. 5. Release the clutch (and the regular brakes) as you normally would. When you release the clutch, the power take-off will start. Using a Transfer Case Mounted Power Take-Off (Automatic Transmission) 1. Set the parking brake. 2. Shift the transfer case into“N’ (Neutral). 3.
Every vehicle is ready for some trailertowing. If it was built with trailering options, as many are, it’s ready for heavier trailers. But trailering is different than just driving your vehicle by itself. Traileringmeans changes in handling, durability, and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly. That’s the reason for this section. Init are many time-tested, important trailering tips and safety rules.
Weight of the Trailer Tongue The tongue load (A) of any trailer is an important weight to measure because it affects the total or gross weight of your vehicle. The gross vehicle weight (GVW) includes the curb weight of the vehicle, any cargo you may carry in it, and the people who will be riding in the vehicle. And if you will tow a trailer, you must add the tongueload to the GVW because your vehicle will be carrying that weight, too.
from the front edge of the foot tothe middle of the hitch ball socket. If the distance is less than 12 inches, take the foot off the trailer tongue. 0 If you’ll be pulling a trailer that, when loaded, will weigh more than 4,000 pounds (1 8 14 kg) be sure to use a properly mounted, weight-distributing hitch and sway control of the proper size. This equipment is very important for proper vehicle loading and good handling when you’re driving.
Before you start, checkthe trailer hitch and platform, safety chains, electrical connector, lights, tires and mirror adjustment. If the trailer has electric brakes, start your vehicle and trailer moving and then apply the trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection at the same time. During your trip, check occasionally to be sure that the load is secure, and that the lights and any trailer brakes are still working.
Driving On Grades Reduce speed and shift to a lower gearbefore you start down a long or steep downgrade.If you don’t shift down, you might have touse your brakes so much that they would get hot and no longerwork well. On a long uphill grade,shift down and reduce your speed to around45 mph (70 km/h) to reduce the possibility of engine and transmission overheating. When towing at high altitude with steep uphill grades,you need to consider the following information.
A CAUTION: It can bedangerous to get out of your vehicleif the shift leveris not fully in“P” (Park) with the parking brakefirmly set.Your vehicle can roll. If’you have leftthe engine running, the vehicle can move suddenly. You or otherscould beinjured. To be sure your vehicle won’t move, even when you’re onfairly level ground, use the steps that follow.

Hazard Warning Flashers Your hazard warning flashers let you warn others. They alsolet police know you have a problem. Your front and rear turn signal lights will flash on and off. But they won’t flash if you’re braking. Press the button in to make your front and rear turn signals 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, pull out on the collar.
Other Warning Devices If you carry reflective triangles,you can use them to warn others. Set oneup at the side of the road about 300 feet (1 00 m) behind your vehicle. Jump Starting If your battery (or batteries) has run down, you may want to use anothervehicle and some jumper cables to start your vehicle. But please follow the steps below to do it safely. things NOTICE: Ignoring these steps could result incostly damage to your vehicle that wouldn’t be covered by your vehicle warranty.
To Jump Start Your Vehicle 1. Check the other vehicle. It must have a 12-volt battery with a negative ground system. I NOTICE: If the other system isn’t a 12-volt system with a negative ground, both vehicles can be damaged. If you have a diesel engine vehicle with two batteries (or more), you should know before you begin that, especially in cold weather, you may not be able to get enough power from a single battery in another vehicle to start your diesel engine.
5. Check that the jumper cables don't have loose ormissing insulation. 'Ir' they do, you could get a shock. Thevehicles could be damaged, too. Before you connect the cables, here are some basic things you should know. Positive (+) will go to positive (+) and negative (-) will go to negative (-) or a metal engine part. Don't connect (+) to (-) or you'll get a short that would damage the battery and maybe other parts, too.
7. Don’t let the other end touch metal. Connect it to the positive (+) terminal of the good battery. Use a remote positive (+) terminal if the vehicle has one. 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. It goes to a heavy unpainted metal part of the vehicle with the dead battery.
9. Attach the cable atleast 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 gettingback to the battery is much less. 10. :Now start the vehicle with the good battery and run the engine for awhile. 1 1. ‘Try to start the vehicle with the dead battery. If it won’t start after a few tries, it probably needs service. .Remove Cables in this Order: 2 3 1 . Heavy Metal Engine Part 2.
When you call, tell the towing service: That your vehicle has rear-wheel drive, or that it has the four-wheel drive option. The make, model, and year of your vehicle. Whether you can move the shift lever for the transmission and transfer case, if you have one. If there was an accident, what was damaged. When your vehicle is being towed, have the ignition key off. The steering wheel should be clamped in a straight-ahead position, with a clamping device designed for towing service.
Towing From the Front If you have a two-wheel drive vehicle, don’t have your vehicle towed on the rear wheels, unless you must. If the vehicle must be towed on the rear wheels, don’t gomore than 35 mph (56 km/h) or fartherthan 50 miles (80 km) or your transmission will be damaged. If these limits must be exceeded, then the rear wheelshave to be supported on a dolly.
Towing From the Rear r NOTICE: Towing pickup models from the rear while loaded with heavy cargo may cause the frame side rails to flex sufficiently to allow the pickup box to contact the cab and could cause damage to the cab and/or box.
,ngine Overheating You will find a coolant temperature gageon your vehicle instrument panel. If you have a diesel engine, you will also find a low coolant light on your instrument panel. If Steam 1s Coming From YourEngine NOTICE: If your engine catches fire because you keep driving with no coolant, your vehicle canbe badly damaged. The costly repairs would not be covered by your warranty.
If No Steam Is Coming From Your Engine If you get the overheat warning but see or hear no steam, the problem may not be too serious. Sometimesthe engine can get a little too hot when you: Climb a long hill on a hot day. 0 Stop after high speed driving. Idle for long periods in traffic. Tow a trailer. 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, turn it off. 2.
Cooling System-Gas Engines When you decide it's safe to lift the hood, here's what you'll see: A. Coolant recovery tank B. Engine fan(s) C. Radiator pressure cap A CAUTION: If your vehicle has air conditioning, the auxiliary electric 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.
NOTICE: Engine damage from running yourengine without coolant isn’t covered by your warranty. If there seems to be no leak, start the engine again. Seeif the fan speed increases when idle speed is doubled by pushing the accelerator pedal down. If it doesn’t, your vehicle needs service. Turn off the engine.
I NOTICE: In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. Use the recommended coolant. 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 youtry. canYou can add the proper coolant mix directly to the radiator!, but be sure the cooling systemis cool beforeyou do it.
How to Add Coolantto the Radiator 1. You can remove the radiator pressurecap when the cooling system, including the radiator pressure cap and upper radiator hose,is no longer hot. Turn the pressure cap slowly to the left until it first stops. (Don’t press down while turning the pressure cap.) If you hear a hiss, waitfor that to stop. A hiss means there is still some pressure left.
3. Fill the radiator with the proper mix, up to the base of the filler neck. 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.
I 6. Starttheengine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine 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 mix through the filler neck until the level reaches the hase of the filler neck. 8. Then replace the pressure cap. At any time during this procedure if coolant begins to flow out of the filler neck, reinstall the pressure cap.
A CAUTION: If your vehicle has air conditioning, the auxiliary electric fan is not running under the hood can start up even when the engine and can injure you. Keep hands, clothing and tools from away any underhood electric fan. If the coolant inside the coolant surge tank is boiling, don’t do anything else until it cools down. E The coolant level should be slightly above the COLD mark.
I NOTICE: Engine damage from running your engine without coolant isn’t covered by your warranty. If there seems to be no leak,start the engine again. Seeif the fan speed increases when idle speed is doubled by pushing the accelerator pedal down. If it doesn’t, your vehicle needs service. Turn off the engine.

While filling the surge tank, watch to see if coolant begins to stream out the air bleed valve. When coolant begins to stream out, close the valve. 5. With the air bleed valve closed and the coolant surge tank pressure cap off, start the engine and let it >. run until you can feel the upper radiator hose getting hot. Watch out for the engine fan(s).
. ;. . I ..... .. Engine Fan Noise Your vehicle has a clutched engine coolingfan. When the clutch is engaged, the fan spins faster to provide more air to cool the engine. In most every day driving conditions the fan is spinning slower and clutch is not fully engaged. This improves fuel economy and reduces fan noise. Under heavy vehicle loading, trailer towing and/or high outside temperatures, the fan speed increases as the clutch more fully engages. So you may hear an increase in fan noise.
A rear blowout, particularlyon a curve, acts much like a skid and may skid. In any rear blowout, remove require the same correction you’d usea in your foot from the accelerator pedal. Get the vehicle under control by steering theway you want the vehicle to go. It may be very bumpy and noisy, but you can still steer. Gently brake to a stop, well off the road if possible. If a tire goes flat, the next section shows how to use your jacking equipment to change a flat tire safely.

Changing the Tire Start with the jack, the jack handle and the ratchet. If the flat tireis on the rear of the vehicle, you'll need the jack handle extensions also. Attach the jack handle (and jack handle extensions, if needed) to the jack. With the UP marking on the ratchet facing you, rotate the ratchet to the right.
That will lift the jack head a little. Before raising the vehicle, do the following things. Put your spare tire near the flat tire. Remove the wheel trim. - Be careful; the rim edges may be sharp. Don't try to remove it with your bare hands. If your vehicle has wheel nut caps, use the wheel wrench and ratchet, with DOWN facing you, to unscrew and take them off. Then take the hub cap off. If the wheel has a trim ring, remove it byusing the flat end of the wheel wrench.
If the wheel has a smooth center piece or a center piece with recessed nuts, place the flat end of the wheel wrench in the slot on the wheel and pry out gently. Using the wheel wrench and ratchet, with DOWN facing Position the jack under the vehicle.
NOTICE: Raising your vehicle with the jack improperly positioned will damage the vehicle or may allow the vehicle tooff fallthe jack. Be sure tofit the jack lift head into the proper location before raising your vehicle. Front Position I Raise the vehicle by rotating the ratchet to the right. Make sure the UP marking faces you. Use the jack handle extentions if the flat is on the rear of the vehicle. Raise thevehicle far enough off the ground so there is enough room for the spare tire to fit.
Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel. Place the spare on the wheel mounting surface.
Replace the wheel nuts with the rounded end of the nuts toward the wheel. Lower the vehicle by rotating the ratchet to the left. Lower the jack completely.

Service Your GM dealer knows your vehicle best and wants you to be happy with it. We hope you’ll go to your dealer forall your service needs. You’ll get genuine GM parts and GM-trained and supported service people. We hope you’ll want to keep your GM vehicle all GM. Genuine GMparts have one of these marks: Doing Your Own Service Work If you want to do some of your own service work, you’ll want to get the proper GM Service Manual.
NOTICE: If you try to do your own service work without knowing enough about it, your vehicle could be damaged. _ _ . Maintenance Schedule Section 7 of this manual, “Scheduled Maintenance Services”, explainsthe maintenance your new vehicle needs, and when it should be done. It also has a form that you can use to record the maintenance work done on your vehicle. Be sure to read this information.
NOTICE: Fuel that is morethan 5 % methanol is bad for your vehicle. Don’t useit. It can corrode metal partsin your fuel system and also damage plasticand rubber parts. That damage wouldn’t be covered under your warranty. And even at 5% or less, there must be “co~olvent~” and corrosion preventersin this fuel to help avoid these problems. Gasolines for Cleaner Air Your use of gasoline with deposit control additives will help prevent deposits from formingin your engine and fuel system.
Fuel Requirements NOTICE: Diesel fuel or fuel additives not recommended in this manual could damage yourfuel system and engine. Your warranty wouldn’t cover this damage. And: Diesel fuel that hasbeen mixed with engine oil could damage your engine and emission controls. Always check withyour service station operator to makesure his diesel fuel has not been mixed with engine oil. If you ever run outof diesel fuel, it can be difficult to restart your engine.
Cold Weather Operation In cold weather (below 20”F, or -7”C), use 1-D or “Winterized” Number 2-D fuel (a blend of I-D and 2-D). Be sure you get the right fuel. In very cold temperatures (when it stays below 0°F or -1 8OC), use Number 1-D. If you’re driving in very cold temperatures and can’t get Number I-D or a “winterized” Number 2-D, you can use one gallon of kerosene for every two gallons of diesel fuel. Onceyou add the kerosene, run your engine for several minutes so the fuels will mix.
If the light comes on at any other time, use this chart. “Water in Fuel” Light Chart Problem Light comes on intermittently. Recommended Action Drain water from fuel filter. Light stays on: 1. At temperatures above freezing. Drain fuel filter immediately. If no water can be drained and light stays on, seeyour dealer for assistance. 2. At temperatures below freezing. Drain fuel filter immediately. If no water can be drained - water may be frozen. Open the air bleed valve to check for fuel pressure.
1 I 4. With the engine off, open the water drain valve 2 to 3 turns. When standing in front of the vehicle, the valve is located on the right side of the thermostat housing. 5 . Start the engine and allow it to idle until clear fuel is observed. 6. Stop the engine and close the water drain valve. 7. Remove the fuel-resistant container and properly dispose of the contaminated fuel.
~ NOTICE: If there is water in your diesel fuel and the weather iswarm or humid, fungus and bacteria can grow in thefuel. Theycan damage your fuel system. You'll needa diesel fuel biocideto sterilize your fuel system. Your dealer can advise you if youever need this. If your fuel tank needs to be purged to remove water, seeyour dealer or a qualified technician. Improper purging can damage your fuel system.
A CAUTION: Diesel fuel is flammable. It could start a fire if it gets on hot engine parts. You could beburned. Don’t let too much fuelflow from theair bleed valve, and wipe up any spilled fuel witha cloth. 3. Close the air bleed valve. 4. Turn the ignition key to “Start” for 10 to 15 seconds at a time until your engine starts.
4. Unscrew and remove the ring nut from thetop of the filterhead. 5. Lift the element out of the filter head. 6. If there is any dirt on the element sealing surface of the filter head, clean it off. 7. Line up the writing on the top of the filter so it faces (is readable from) the front of the vehicle. Push the element in until the mating surfaces touch. 8. With the air bleed valve open, turn your ignition key to START for 10 to 15 seconds. Wait one minute for your starter to cool.
9. Close the air bleed valve and replace the fuel cap. 10. Start your engine and let it idle for fiveminutes. Check your fuel filter and air bleed valve for leaks. Fuels in Foreign Countries If you plan on driving in another country outside the U.S. or Canada, unleaded fuel may be hard to find. Donot use leaded gasoline. If you use even one tankful, your emission controls won’t work well or at all.
While refueling, hang the cap inside the fuel door. To take off the cap, turn it slowly tothe left. Be careful not to spill gasoline. Clean gasoline from painted surfaces as soon as possible. See “Cleaning the Outside of Your Vehicle” in theIndex. When you put the cap back on, turn it to the right untilyou hear a clicking noise. I NOTICE: If you need a new cap, be sure to get the right type. Your dealer can get one for you.
Checking Things Under the Hood Iood Release To open the hood, first pull the handle inside the vehicle. Then go to the frontof the vehicle and pull up on the secondary hood release, locatedjust to the passenger sideof the centerof the grill. Lift the hood. Your vehicle, if it has air conditioning,may have a auxiliary engine fan in addition to the belt drivenfan.
I Things that burncan get on hot engine parts and start a fire. These includeliquids like gasoline or diesel fuel, oil, coolant, brake fluid, windshield washerand otherfluids, and plastic or rubber. You or others could beburned. Be careful not to drop or spill things that will burn onto a hot engine. Before closing the hood, be sure all filler caps are on properly. Pull down the hood and close it firmly.
Tampering With Noise Control System Prohibited Federal law prohibits the following acts orthe causing thereof: 1 . The removal or rendering inoperative by any person, other than for purposes of maintenance, repairor replacement, of any device or element of design incorporated into any new vehicle for the purpose of noise control, prior to its sale or deliveryto the ultimate purchaser or while it is in use; or 2.
Turn off the engine and give the oil a few minutes to drain back into the oil pan. If you don’t, the oil dipstick might not show the actual level. I I To Check EngineOil I Pull out thedipstick and clean itwith a paper towel or cloth, then push it back in all the way. Remove itagain, keeping the tip lower. When to Add Oil If the oil isat or below the ADD mark, then you’ll need to add some oil. But you must usethe right kind. This section explains what kind of oil to use.
The engine oil filler cap is located on the driver’s side engine valve cover. Just fill it enough to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you’re through. What Kind of Oil to Use Beginning midyear 1993, oils of the proper quality for your vehicle will be identified with this new “starburst” symbol.
You should also use the proper viscosity oil for your vehicle, as shown in the following chart: LIGHT DUTY EMISSIONS -GAS ENGINES RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS FOR BEST FUEL ECONOMY AND COLD STARTING, SELECT THE LOWEST SAE VISCOSITY GRADE OIL FOR THE EXPECTED TEMPERATURE RANGE.
HEAVY DUTY EMISSIONS -GAS ENGINES RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS FOR BEST FUEL ECONOMY AND COLD STARTING, SELECT THE LOWEST SAE VISCOSITY GRADE OIL FOR THE EXPECTED TEMPERATURE RANGE.
If you cannot find oils with the new “starburst” symbol on the front of the container, you should look for and use oils containing the following three things: SHor SG “SH” or “SG” must be on the oil container, either by itself or combined with other quality designations, such as “SH/CD,” “SH,SG,CD,” “SG/CD,” etc. Theseletters show American Petroleum Institute (API) levels of quality.
Engine Oil Additives Don’t add anything to your oil. Your GM dealer is ready to advise if you think something should be added. When to Change Engine Oil See if any one of these is true for you: Most trips are less than 4 miles (6 km). It’s below freezing outside and most trips are less than 10 miles (16 km). The engine is at low speed most of the time (as in door-to-door delivery, or in stop-and-go traffic). You tow a trailer often. Most trips are through dusty places.
What to Do with Used Oil Did you know that used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer? Don't let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly throw away clothing or rags containing used engine oil. (Seethe manufacturer's warnings about the use and disposal of oil products.) Used oil can be a real threat to the environment. If you change your own oil, be sure t.
To Check Engine Oil Pull out the dipstick and clean it with a paper towel or a cloth, then push it back in all the way. Remove it again, keeping the tip lower. When to Add Oil If the oil is at or below the ADD line, then you’ll need to add someoil. But you must use the right kind. This section explains what kind of oil to use. For crankcase capacity, see “Capacities and Specifications” in the Index. NOTICE: Don’t add too much oil.
The engine oil filler cap is located on a filler tube at the front of the engine. Just fill it enough to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you’re through. What Kind of Oil to Use Look for these two things: CF4SH C F 4 S H is the best oil for your vehicle. However, if you can not find CF4/SH oil, you may use CF-4/SG or CE/SH or CE/SG oil. These may be listed as shown or in reverse order, for example SHEF-4.

This doughnut-shaped logo (symbol) is used on most oil containers to help you select the correct oil. You should look for this on the oil container, and use only those oils that display the logo. GM Goodwrench@oil (in Canada, GM Engine Oil) meets all the requirements foryour vehicle. Engine Oil Additives Don’t add anything to your oil. Your GM dealer is ready to advise if you think something should be added.
Air Cleaner Refer to the Maintenance Schedule to determine when to replace the air filter. See “Scheduled Maintenance Services” in the Index. NOTICE: If the air cleaner is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner in place when you’re driving.
- 1 To remove the air .-. cleaner filter on a gas engine or a6.5 liter naturally aspirated diesel, turn the wing nuts to the left. Remove the cover and change the filter. Then, unhook the cover retaining clips and push the rear of the cover toward the engine. Automatic Transmission Nuid When to Check and Change A good time to check your automatic transmission fluid level is when the engine oilis changed. Refer to the Maintenance Schedule to determine when to change your fluid.
I NOTICE: Too much or too little fluid can damage your transmission. Too much can mean that someof the fluid could come out and fall on hot engine parts or exhaust system, starting a fire. Be sure to get an accurate readingif you check your transmission fluid. Wait at least 30 minutes before checking the transmission fluid level if you have been driving: 0 When outside temperatures are above90°F (32°C). At high speed for quite a while. 0 In heavy traffic - especially in hot weather.
Then, .without shutting ofithe engine, follow these steps: 1. Flip the handle up and then pull out the dipstick and wipe it with a clean rag or paper towel. 2. Push it back in all the way, wait three seconds and then pull it back out again. 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. 4.
How to Add Fluid Refer to the Maintenance Schedule to determinewhat kind of transmission fluid to use. See “Recommended Fluids and Lubricants” in the Index. If the fluid level is low, add only enough of the proper fluid to bring the level up to the COLD area for a cold check or the HOT area for a hot check. It doesn’t take much tluid, generally less than a pint. Don’t overfill.
Then, follow these steps: I . Remove the filler plug. 2. Check that the lubricant level is up to the bottom of the filler plug hole. 3. If the fluid level is good, install the plug and be sure it is fully seated. If the fluid level is low, add more fluid as described in the next 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. I . Remove the filler plug. 2.
When to Check and Whatto Use 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 ridded if the level does not reach the bottom of the diaphragm when it’s in place i n the reservoir. See the instructions on the reservoir cap.
How to Check Lubricant If the level is below the bottom of the filler plug hole, you’ll need to add some lubricant. Add enough lubricant to raise the level to the bottom of the filler plug hole. What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use. See “Recommended Fluids and Lubricants” in the Index. Four- Wheel Drive Most lubricant checks in this section also apply to four-wheel-drive vehicles. However, they have two additional systems that need lubrication.
How to Check Lubricant - If the level is below the bottom of the filler plug hole, you’ll need to add some lubricant. Add enough lubricant to raise the level to the bottom of the filler plug hole. What to Use Refer to the Maintenance Scheduleto determine what kind of lubricant to use. See “Recommended Fluids and Lubricants” in the Index. 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.
What to use Refer to the Maintenance Schedule to determine what kind of lubricant to use. See “Recommended Fluids and Lubricants” in the Index. Engine Coolant The following explains yourcooling system and how to add coolant when it is low. If you have a problem with engine overheating, see “Engine Overheating” in the Index. The proper coolant for your vehicle will: Give freezing protection down to -20 OF (-29”C), or -34°F (-37°C) in Canada and for vehicles with the cold climate option.
I NOTICE: If you use an impropercoolant mix, your engine could overheat and be badly damaged. The repair cost wouldn’t becovered by your warranty. Too much water in the mix can freeze and crack the engine, radiator, heater core and other parts. Some conditions, such as airtrapped in the cooling system, can affect the coolant level in the radiator. Check the coolant level when the engine is cold and follow the stepsunder “Adding Coolant” forthe proper way to add coolant.
To Add Coolant If you need more coolant, add the proper mix at the coolant recovery tunk. A CAUTION: Turning the radiatorpressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. Withthe coolant recoverytank, you will almost never haveto addcoolant at the radiator. Never turn the radiator pressure cap - even alittle -when the engine and radiator arehot. Add coolant mix at the recovery tank, but be careful not to spill it.
To Check Coolant When your engine is cold, the coolant level should be at the COLD mark, or a little higher. When your engineis warm, the level should be above the COLD mark. If this light comes on, it means you’re low on engine coolant. To Add Coolant If you need more coolant, add the proper mix at the surge tnnk, but only when the engine is cool. Open the air bleed valve on the thermostat housing to allow trapped air out of the system. Close the bleed valve when coolant begins to flow out.
Radiator Pressure Cap-Gas Engines 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 capis a 15 psi (105 kPa) pressure-type cap and loss and possible must be tightly installed to prevent coolant on the cap engine damage from overheating. Be sure the arrows line up with the overflow tube on the radiator filler neck.
NOTICE: Your surge tank pressure cap is a unique 15 psi (105 kPa) pressure-type cap foruse with surge tankcooling systems only. It mustbe tightly installed to prevent coolant loss and possible engine damage fromoverheating. Be sure the arrowson the cap line up with the top tubeof the coolant surge tank. Thermostat Engine coolant temperatureis controlled by a thermostat in the engine coolant system. The thermostat stops the flow of coolant through the radiator until the coolant reaches a preset temperature.
When the engine compartment is hot, the level should be at the FULL mark. When the engine compartment is cool, the level should be at the FULL COLD mark. What to Add Refer to the Maintenance Schedule to determine what kind of fluid to use. See “Recommended Fluids and Lubricants” in the Index. NOTICE: When adding power steering fluid or making a complete fluid to use the proper change, always use the proper fluid. Failure fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid To Add Open the cap labeled “WASHER FLUID ONLY.” Add washer fluid untilthe bottle is full. NOTICE: When using concentrated washer fluid, follow the manufacturer’s instructions for adding water. Don’t mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage your washer fluid tank and other parts of the washer system. Also, water doesn’t cleanas well as washer fluid. Fill your washer fluidtank only 314 full when it’s very cold.
Brakes Brake Master Cylinder Your brake master cylinder is here. It is filled with DOT-3 brake fluid. There are only two reasons why the brake fluid level in your master cylinder might go down, The first is that the brake fluid goes down to an acceptable level during normal brake lining wear. When new linings are put in, the fluid level goes back up. The other reason is that fluid is leaking out of the brake system.
To Check BrakeFluid You can check the brake fluid without taking off the cap. Just look atthe windows on the brake fluid reservoir. The fluid levels should be above “MIN.” If they aren’t, have your brake system checked tosee if there is a leak. After work is done on the brake hydraulic system, make sure the levels are above “MIN” and belowthe top of each window. What to Add When you do need brake fluid, use only DOT-3 brake fluid- such as Delco Supreme l l @(GM Part No.1052535).
Brake Wear Your vehicle has front disc brakes and rear drum brakes. If you have a C 3500 HD model, it has four-wheel disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and go or be heard all the time your vehicle is moving (except when you are pushing on the brake pedal firmly). The brake wear warning sound means that sooner or later your When brakes won’t work well.
Brake Adjustment Every time you make a brake stop, your disc brakes adjust for wear. If your brake pedal goes down fartherthan normal, your rear drum brakes may need adjustment. Adjust them by backing up and firmly applying the brakes a few times. Replacing Brake System Parts The braking system on a modern 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.
Wheel Nut Torque For vehicle with dual wheels, wnen the vehicle, wheel or Tasteners are new, have the torque set at the first 100, 1,000and 6,000 miles (1 60, 1600 and 9600 km). Use the torque specified in the appropriate Specification Chart later in this section. Single Belt Accessory Drive If your new vehicle uses a serpentine belt, it is lighter and more durable than systems with several belts. The belt runs over or around the pulleys on the engine.
Fluid LeakCheck After the vehicle has been parked for a while, inspect the surface under the vehicle for water, oil, fuel or other fluids.Water dripping from the air conditioning system after it has been used is normal. If you notice fuel leaks or fumes,the causes should be found and corrected at once. Lubrication Accelerator Control System Your maintenance schedule will tell you how often the accelerator linkage pivot points must be lubricated.
Never use toomuch of any lubricant and be sure to wipe up any extra lubricant when you are finished. Your maintenance schedule will tell you how often to lubricant these items. See “Recommended Fluids and Lubricants” in the Index for the proper lubricant to use. Lock Cylinders To be sure your locks operate properly, they must be lubricated. Your vehicle’s maintenance schedule will tell you how often to lubricate them. See “Recommended Fluids and Lubricants” in the Index for the proper lubricant to use.

Fuses and Circuit Breakers The wiring circuitsin your vehicle are protected from short circuits by a combination of fuses, circuit breakers, and fusible thermal links in the wiring itself. This greatly reduces the chance of fires caused by electrical problems.
Trailer Wiring Harness The optional seven-wire trailer wiring harness is protected by an in-line fuse in the battery feed wire. This fuse is near the junction block. See “Trailer Wiring Harness” in the Index for more information. Fuse Block The fuse block is behind an access door at the bottom of the instrument panel, next to the parking brake release lever. To remove fuses if you don’t have one, hold the end of the fuse between your thumb and index finger and pull straight out.
Exhaust System To help prevent damage to your exhaust system,do not continue to drive your vehicle if you notice: Engine misfiring 0 Loss of performance Other unusual operating conditions Have your engine and exhaust system serviced regularly. Three- Way Catalytic Converter (gas engines) Your vehicle’s three-way catalytic converteris designed to reduce the pollutants in your vehicle’s exhaust. Use only unleaded fuel in your vehicle.
Malfunction Indicator (SERVICE ENGINESOON) Lamp The Malfunction Indicator (SERVICE ENGINE SOON) Lamp on your instrument panel lets you know when your emission system needs service. The light will come on briefly when you start your engine to let you know that the system is working. If it does not come on when you start your engine, or if it comes on and stays on while you’re driving, your system may need service. Your vehicle should still be driveable, but you should have your system serviced right away.
A CAUTION: In the case of a sudden stop or collision, thingscarried in the bed of your truck could shift forward and come into the passenger area, injuringyou and others. If you put things in the bed of your truck, you should makesure they are properly secured. A CAUTION: Do not load your vehicle any heavier than theGVWR or the maximum front and rear GAWRs. If you do,parts on your vehicle-canbreak, or itcan change the way your vehicle handles. These could causeyou to lose control.
Trailering Package If your vehicle comes with the Trailering Package,there is also a load rating which includes the weight of the vehicle and the trailer it tows. This rating is called the Gross Combination Weight Rating (GCWR). When you weigh your trailer, be sure to include the weight of everything you put in it. And, remember to figure theweight of the people inside as part of your load. Your dealer can help you determine your GCWR.
Add-on Equipment When you carry removable items, like snow plow blades, you may need to put a limit on how many people you carry inside your vehicle. Be sure to weigh your vehicle before you buy and install the new equipment. i NOTICE: Your warranty doesn’t cover partsor components that fail because of overloading.
TRUCK LOADING INFORMATION A 0 I . Recommended location for cargo center of gravity for cargo weight rating (Pickup Truck). Refer to the Truck Camper Loading Information label in glove box for “A”and “B” dimensions. Use the rear edge of the load floor for measurement purposes. EXAMPLE OF PROPER TRUCK AND CAMPER MATCH 1 . Camper center of gravity 2. Recommended center of gravity location zone. The camper’s centerof gravity should fall within the center of gravity zone for your vehicle’s cargo load.
After you’ve loaded your vehicle and camper, drive to a weigh station and weigh on the front and rear wheels separately. This will tell you the loads on your axles. Theloads on the front and rear axles shouldn’t be more than either of the GAWRs. The total of the axle loads should not be more than the GVWR. Open your driver’s door and look at the CertificatiodTire label to find out your CWAR and GVWR.
Tires We don’t make tires. Your new vehicle comes with high quality tires made by a leading tire manufacturer. These tires are warranted by the tire manufacturers and their warranties are delivered with every new vehicle. If your spare tire is a different brand than your road tires, you will have a tire warranty folder from each of these manufacturers.
find the load on each tire and see the label for the minimum cold inflation pressures for that load. NOTICE: Don’t let anyonetell you that underinflation or overinflation is all right. It’s not. If your tiresdon’t have enough air (underinflation) you can get: Too much flexing Too much heat Tire overloading Bad wear Bad handling Bad fuel economy. If your tireshave too much air (overinflation), you can get: Unusual wear Bad handling Rough ride ‘Needlessdamage from road hazards.
Special Tire lnflation If you have 16 inch tireson your vehicle, and: - You’ll be drivingfor very long at speeds of 66 mph (105 km/h) to 75 mph (120 km/h) where legal,inflate tires to 10 psi (70 kPa) more than the recommended cold inflation pressures. - You’ll be drivingfor very long at speeds of76 mph (120 km/h) to 85 mph (135km/h) where legal, cold inflation pressures should be increased by 10 psi (70 kPa) and you must also reduce axle load capacity by 10%.
If your vehicle has front tires with different load ratings or tread designs (such as all season vs. on/off road) than the rear tires, don’t rotate your tires front to rear. After the tires have been rotated, adjust the front and rear inflation pressure as shown on the CertificatiodTire label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” in the Index.
Dual Tire Rotation Use one of these patterns if you have the same tire sizes and load ranges on the front and rear. Use this pattern if your front and rear tires are different sizes or load ranges. The dual rear tires are rotated as a pair and the inside rear tires become the outside rear tires. n When you install dual wheels, be sure the vent holes in the wheels are lined UP.
Dual lire Operation If your vehicle has dual rear wheels, the outer tirewill usually wear faster than the inner tire. Your tires will wear more evenly and last longer if you rotate the tires periodically. If you’re going to be doing a lot of driving on high-crown roads, you can reduce tire wear by adding 5 psi (35 kPa) to the tire pressure in the outer tires. Be sure toreturn to the recommended pressures when no longer drivingunder those conditions.
Uniform Tire Quality Grading The following information relates to the system developed by the United States National Highway Traffic Safety Administration which grades tires by treadwear, traction and temperature performance. (This applies only to vehicles soldin the United States.) Treadwear 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.
While the tires available as standard or optional equipment on General Motors vehicles may vary with respect to these grades, all such tires meet General Motors performance standards and have been approved for use on General Motors vehicles. All passenger type (P Metric) tires must conform to Federal safety requirements in addition to these grades.
NOTICE: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer/odometercalibration, headlight aim, bumper height, vehicleground clearance, and tireor tirechain clearance to the body and chassis. Used Replacement Wheels Tire Chains NOTICE: If your vehicle has dual wheels or LT26Y75R16 sizetires, don’t use tire chains; they can damage your vehicle.
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 aredangerous if you breathe their fumes in a closed space. When you use anything from a container to clean your vehicle, be sure to follow the manufacturer's warnings and instructions. And always open your doors or windows when you're cleaning the inside.
Cleaning the Insideof Your Vehicle Use a vacuum cleaner often toget rid of dust and loose dirt. Wipe vinyl or leather with a clean, damp cloth. Your GM dealerhas two GM cleaners, a solvent-type spot lifter and a foam-type powdered cleaner. They will clean normal spots and stains very well. Do not use them on vinyl or leather. Here are some cleaningtips: Always read the instructions on the cleaner label. 0 Clean up stains as soon as you can - before they set.
Using Solvent-Type Cleaner on Fabric First, see if you have to use solvent-type cleaner at all. Some spots and stains will clean off better with just water and mild soap. If you need to use a solvent: 0 Gently scrape excess soil from the trim material with a clean, dull knife or scraper. Use very little cleaner, light pressure and clean cloths (preferably cheesecloth). Cleaningshould start at the outside of the stain, “feathering” toward the center. Keep changing to a clean section of the cloth.
0 If an odor lingers after cleaningvomit or urine, treat the area with a waterhaking soda solution: 1 teaspoon ( 5 ml) of baking soda to I cup (250 ml) of lukewarm water. 0 If needed, clean lightly with solvent-type cleaner. Combination Stains Such as candy, ice cream, mayonnaise,chili sauce and unknown stains. Carefully scrape off excess stain, then clean with cool water and allow to dry. 0 If a stain remains, cleanit with solvent-type cleaner. Cleaning Vinyl Use warm water and a clean cloth.
Care of Safety Belts Keep belts clean and dry. Glass Glass should be cleaned often. GM Glass Cleaner (GM Part No. 1050427) or a liquid household glass cleaner will remove normal tobacco smokeand dust films. Don’t use abrasive cleaners onglass, because they may cause scratches. Avoid placing decals on the inside rear window, since they may have to be scraped off later. If abrasive cleaners areused on the inside of the rear window, an electric defogger elementmay be damaged.
Washing Your Vehicle The best way to preserve your vehicle’s finish is to keep it clean by washing it often with lukewarmor cold water. Don’t wash your vehiclein the direct raysof the sun. Don’t use strong soaps or chemical detergents. Use liquid hand, dish or car washing (mild detergent) soaps. Don’t use cleaning agents that contain acid or abrasives. All cleaning agents should be flushed promptly and not allowed to dry on the surface,or they could stain.
Aluminum Wheels (IfSo Equipped) Your aluminum wheels have a protective coating similar to the painted surface of your vehicle. Don’t use strong soaps, chemicals, chrome polish, abrasive cleanersor abrasive cleaning brushes on them because you could damage this coating. After rinsing thoroughly, a wax may be applied. NOTICE: If you have aluminum wheels, don’t use an automatic vehicle wash that has hard silicon carbide cleaning brushes. These brushes can takeoff the protective coating.
Underbody Maintenance 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, tlush these materials from the underbody with plain water. Clean any areas where mud and other debris can collect.

Recording Maintenance Services............................... 7-3 Scheduled Maintenance Services...............................
A Word About Maintenance 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 distancesonly a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands, orin many other ways. Because of all the different ways people use their GM vehicles, maintenance needs vary.
Tf you are skilled enoughto do some work on your vehicle, you will probably want to get the service information GM publishes. For information on how to obtain various service publications for your vehicle, see “Service Publications” in the Index. You will find a list of publications and an order form in the back of the book. Scheduled Maintenance Services This part tells you the maintenance services that you should have done and the times you should schedule them.
