Seats and Seat Controls This section tells you about the seats them, and fold them up and down. 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.
Page 16 Manual Lumbar Support (If Equipped) If you have this feature, there will be a knob on the outside of the driver’s bucket seat. Turn the knob toward the front of the vehicle to increase lumbar support and toward the rear of the vehicle to decrease lumbar support.
Page 17 But don’t have a seatback reclined if your vehicle is moving. 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.
Page 18 Seatback Latches (Regular or Extended Cab Only) The front seatback folds forward to let people get into the rear seat or to access the storage area behind the seat. To fold the front seatback forward, push the lever on the side of the seat rearward and pull the seatback forward.
Page 19 Easy Entry Seat (Extended Cab Models) The right front bucket or split bench seat of your vehicle makes it easy to get in and out of the rear vehicle area.

Page 21: Why Safety Belts 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. 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.

or the safety belts! With safety belts, you slow down as the vehicle does. You get more time to stop. You stop over more distance, and your strongest bones take the forces. That’s why safety belts make such good sense. Here Are Questions Many People Ask About Safety Belts and the Answers...
Page 25: How To Wear Safety Belts Properly
If I’m a good driver, and I never drive far from home, why should I wear safety belts? You may be an excellent driver, but if you’re in an accident even one that isn’t your fault your passengers can be hurt. Being a good driver doesn’t protect you from things beyond your control, such as bad drivers.
Page 26 3. Pick up the latch plate and pull the belt across you. Don’t let it get twisted. The shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly.
Page 27 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.
Page 28 What’s wrong with this? The shoulder belt is too loose. It won’t give nearly as much protection this way. 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.
Page 29 What’s wrong with this? The belt is buckled in the wrong place. 1-16 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.
Page 30 What’s wrong with this? The shoulder belt is worn under the arm. It should be worn over the shoulder at all times. 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.
Page 31 What’s wrong with this? The belt is twisted across the body. 1-18 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.
Page 32: Safety Belt Use During Pregnancy
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.
Page 33: Right Front Passenger Position
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.
Page 34 CAUTION: You can be severely injured or killed in a crash if you aren’t wearing your safety belt 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”...
Page 35 CAUTION: Anyone who is up against, or very close to, any air bag when it inflates can be seriously injured or killed. 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.
Page 36 How the Air Bag System Works Where are the air bags? The driver’s air bag is in the middle of the steering wheel. The right front passenger’s air bag is in the instrument panel on the passenger’s side. 1-23...
Page 37 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.
Page 38 How does an air bag restrain? In moderate to severe frontal or near 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.
Page 39 Let only qualified technicians work on your air bag system. Improper service can mean that your air bag system won’t work properly. See your dealer for service. NOTICE: If you damage the covering for the driver’s or the right front passenger’s air bag, the bag may not work properly.
Page 40 This switch should only be turned to AIR BAG OFF if the person in the right front passenger’s position is a member of a passenger risk group identified by the national government as follows: Infant. An infant (less than 1 year old) must ride in the front seat because: my vehicle has no rear seat;...
Page 41 To turn off the right front passenger’s air bag, insert your ignition key into the switch, push in, and move the switch to AIR BAG OFF. The AIR BAG OFF light will come on to let you know that the right front passenger’s air bag is off. The right front passenger’s air bag will remain off until you turn it back on again, and the AIR BAG OFF light will stay on to remind you that the air bag is off.
Page 42 To turn the right front passenger’s air bag on again, insert your ignition key into the switch, push in, and move the switch to the ON position. 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.
Page 43: Center Passenger Position
Adding Equipment to Your Air Bag-Equipped Vehicle 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? 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.
Page 44 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.
Page 45: Rear Seat Passengers
Rear Seat Passengers (Extended Cab Jump Seats) Lap Belt These are reserve seating positions equipped with lap belts only. (If your extended cab pickup has the optional side access panel, there’s only one reserve seating position.) 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.
Page 46: Rear Seat Passengers
To make it shorter, pull the belt as shown until it is snug. Buckle and position it the same way as the lap part of the driver’s safety belt. See “Driver Position” in the Index. 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.
Page 47 Shoulder Belt (Crew Cab) The positions next to the windows have lap belts. Here’s how to wear one properly. 1-34 1. Pick up the latch plate and pull the belt across you. Don’t let it get twisted. The shoulder belt may lock if shoulder you pull the belt across you very quickly.
Page 48 3. To make the lap part tight, pull down on the buckle The lap part of the belt should be worn low and snug on end of the belt as you pull up on the shoulder part. the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones.
Page 49 The safety belt locks if there’s a sudden stop or a crash. The safety belt also locks if you pull the belt very quickly out of the retractor. CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury.
Page 50: Children
Children Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle.
Page 51 CAUTION: People should never hold a baby in their arms while riding in a vehicle. A baby doesn’t weigh much until a crash. During a crash a baby will become so heavy it is not possible to hold it. For example, in a crash at only 25 mph (40 km/h), a lb.
Page 52 CAUTION: Children who are up against, or very close to, any air bag when it inflates can be seriously injured or killed. Air bags plus lap shoulder belts offer outstanding protection for adults and older children, but not for young children and infants. Neither the vehicle’s safety belt system nor its air bag system is designed for them.
Page 53 CAUTION: Newborn infants need complete support, including support for the head and neck. This is necessary because a newborn infant’s neck is weak and its head weighs so much compared with the rest of its body. In a crash, an infant in a rear facing seat settles into the restraint, so the crash forces can be distributed across the...
Page 54: Restraint Systems For Children
Restraint Systems for Children An infant car bed (A), a special bed made for use in a motor vehicle, is an infant restraint system designed to restrain or position a child on a continuous flat surface. Make sure that the infant’s head rests toward the center of the vehicle.
Page 55 A forward facing child seat (C E) provides restraint for the child’s body with the harness and also sometimes with surfaces such as T shaped or shelf 1-42 A booster seat (F improve the fit of the vehicle’s safety belt system. Some like shields.
Page 56 How do child restraints work? A child restraint system is any device designed for use in a motor vehicle to restrain, seat, or position children. A built in child restraint system is a permanent part of the motor vehicle. An add child restraint system is a portable one, which is purchased by the vehicle’s owner.
Page 57 Where to Put the Restraint (Regular Cab and Extended Cab Pickup) The child restraint must be secured properly in the right front passenger seat. If you want to secure a rear child restraint in the right front passenger’s seat, turn off the passenger’s air bag.
Page 58: Top Strap
There is limited space in the rear seating area of a crew cab pickup model. If you want to secure a child restraint in a rear outside seating position of a crew cab model, be sure to study the instructions that came with your child restraint to see if there is enough room to secure your seat properly.
Page 59 In Canada, the law requires that forward restraints have a top strap, and that the strap be anchored. In the United States, some child restraints also have a top strap. If your child restraint has a top strap, it should be anchored. Anchor the top strap to this bracket (regular or extended cab).
Page 60 When using a top strap equipped child restraint in a rear outboard seating position of a crew cab model, route the top strap through the opening in the head restraint. Then, attach it to the anchor point for that seating position. Once you have the top strap anchored, you’ll be ready to secure the child restraint itself.

Page 62 5. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. If you’re using a forward facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt.
Page 63: Front Seat Position
Jump Seats (Extended Cab) Don’t use child restraints in these positions. The restraints won’t work properly. 1-50 Securing a Child Restraint in the Right Front Seat Position Your vehicle has a passenger air bag. If your vehicle is a regular cab pickup or an extended cab pickup, 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...
Page 64 Unless your vehicle has the air bag off switch and the passenger’s air bag has been turned off, never put a rear facing child restraint in the right front passenger’s seat. Here’s why: CAUTION: A child in a rear facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates.
Page 65 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. If this ever happens, don’t let anyone whom the national government has identified as a member of a passenger air bag risk group sit in the right front...

If possible, an older child should wear a shoulder belt and get the additional restraint a...
Page 69 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. 1-56 What if a child is wearing a lap but the child is so small that the shoulder belt is...
Page 70 CAUTION: Never do this. Here a child is sitting in a seat that has a 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.
Page 71: Safety Belt Extender
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.
Page 72 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.
Page 73 Windows CAUTION: Leaving children in a vehicle with the windows closed is dangerous. A child can be overcome by the extreme heat and can suffer permanent injuries or even death from heat stroke. Never leave a child alone in a vehicle, especially with the windows closed in warm or hot weather.

Page 179 Section 4 Your Driving and the Road Here you’ll find information about driving on different kinds of roads and in varying weather conditions. We’ve also included many other useful tips on driving. Defensive Driving Drunken Driving Control of a Vehicle Braking Steering Road Recovery...
Page 180: Defensive Driving
Defensive Driving The best advice anyone can 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.”...
Page 181: Drunken Driving
Drunken Driving Death and injury associated with drinking and driving is a national tragedy. It’s the number one contributor to the highway death toll, claiming thousands of victims every year. Alcohol affects four things that anyone needs to drive a vehicle: Judgment Muscular Coordination Vision...
Page 182 It’s the amount of alcohol that counts. For example, if the same person drank three double martinis (3 ounces or 90 ml of liquor each) within an hour, the person’s BAC would be close to 0.12 percent. A person who consumes food just before or during drinking will have a somewhat lower BAC level.
Page 183 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.
Page 184: Control Of A Vehicle
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.
Page 185: Anti-Lock Brakes (Abs)
Avoid needless heavy braking. Some people drive in spurts heavy acceleration followed by heavy braking rather than keeping pace with traffic. This is a mistake. Your brakes may not have time to cool between hard stops. Your brakes will wear out much faster if you do a lot of heavy braking.
Page 186 Here’s how anti lock works. Let’s say the road is wet. You’re driving safely. Suddenly an animal jumps out in front of you. You slam on the brakes and continue braking. Here’s what happens with ABS. A computer senses that wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each front wheel and at both rear wheels.
Page 187: Steering
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.
Page 188: Steering In Emergencies
Speed limit signs near curves warn that you should adjust your speed. Of course, the posted speeds are based on good weather and road conditions. Under less favorable conditions you’ll want to go slower. 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.
Page 189: Off - Road Recovery
Road Recovery You may find 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.
Page 190 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.
Page 191: Loss Of Control
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.
Page 192: Off - Road Driving With Your
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.
Page 193: Environmental Concerns
CAUTION: Cargo on the load floor piled higher than 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.
Page 194: Traveling To Remote Areas
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.
Page 195: Scanning The Terrain
Scanning the Terrain 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.
Page 196: Approaching A Hill
Driving on Off-Road Hills 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.
Page 197 Driving Uphill Once you decide you can safely drive up the hill, you need to take some special steps. Use a low gear and get a firm grip on the steering wheel. Get a smooth start up the hill and try to maintain your speed.
Page 198 What should I do if my vehicle stalls, or is about to stall, and I can’t make it up the hill? If this happens, there are some things you should do, and there are some things you must not do. First, here’s what you should do: Push the brake pedal to stop the vehicle and keep it from rolling backwards.
Page 199: Driving Downhill
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.
Page 200 Are there some things I should not do when driving down a hill? Yes! These are important because if you ignore them you could lose control and have a serious accident. When driving downhill, avoid turns that take you across the incline of the hill. A hill that’s not too steep to drive down may be too steep to drive across.
Page 201: Driving Across An Incline
Driving Across an Incline Sooner or later, an off road trail will probably go across the incline of a hill. If this happens, you have to decide whether to try to drive across the incline. Here are some things to consider: A hill that can be driven straight up or down may be too steep to drive across.
Page 202: Stalling On An Incline
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 to roll over, you’ll be right in its path.
Page 203 Hard packed snow and ice offer the worst tire traction. On these surfaces, 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.
Page 204: Driving At Night
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.
Page 205 Here are some tips on night driving. Drive defensively. Don’t drink and drive. Adjust your inside rearview mirror to reduce the glare from headlamps behind you. Since you can’t see as well, you may need to slow down and keep more space between you and other vehicles.
Page 206: Driving In Rain And On Wet Roads
Driving in Rain and on Wet Roads Rain and wet roads can mean driving trouble. On a wet road, you can’t stop, accelerate or turn as well because your tire 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.
Page 207 Driving too fast through large water puddles or even going through some car washes can cause problems, too. The water may affect your brakes. Try to avoid puddles. But if you can’t, try to slow down before you hit them. CAUTION: Wet brakes can cause accidents.
Page 208: Driving Through Flowing Water
Hydroplaning usually happens at higher speeds. There just isn’t a hard and fast rule about hydroplaning. The best advice is to slow down when it is raining. Driving Through Deep Standing Water NOTICE: If you drive too quickly through deep puddles or standing water, water can come in through your engine’s air intake and badly damage your engine.
Page 209: City Driving
City Driving One of the biggest problems with city streets is the amount of traffic on them. You’ll want to watch out for what the other drivers are doing and pay attention to traffic signals. Here are ways to increase your safety in city driving: Know the best way to get to where you are going.
Page 210: Freeway Driving
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.
Page 211: Before Leaving On A Long Trip
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.
Page 212: Highway Hypnosis
Highway Hypnosis Is there actually such a condition as “highway hypnosis”? Or is it just plain falling asleep at the wheel? Call it highway hypnosis, lack of awareness, or whatever. There is something about an easy stretch of road with the same scenery, along with the hum of the tires on the road, the drone of the engine, and the rush of the wind against the vehicle that can make you sleepy.
Page 213 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. Know how to go down hills. The most important thing to know is this: let your engine do some of the slowing down.
Page 214: Winter Driving
Winter Driving Here are some tips for winter driving: Have your vehicle in good shape for winter. You may want to put winter emergency supplies in your vehicle. 4-36 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.
Page 215 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. You can get wet ice when it’s about freezing (32 F;...
Page 216 If You’re Caught in 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 the snow. Here are some things to do to summon help and keep yourself and your passengers safe: Turn on your hazard flashers.
Page 217: Recreational Vehicle Towing
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.
Page 218: Loading Your Vehicle
Dust or dirt can enter the back of the transmission through the opening created by removing the propeller shaft if proper protection is not provided. Also, check the transmission fluid level before driving the vehicle. When towing your vehicle, turn the ignition to OFF. To prevent your battery from draining while towing, remove the RDO BATT and CLSTR fuses from the instrument panel fuse block.
Page 219 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.
Page 220 CAUTION: Things you put inside your vehicle can strike and injure people in a sudden stop or turn, or in a crash. Put things in the cargo area of your vehicle. Try to spread the weight evenly. Never stack heavier things, like suitcases, inside the vehicle so that some of them are above the tops of the seats.
Page 221 Any load that extends beyond the vehicle’s taillamp area must be properly marked according to local laws and regulations. Remember not to exceed the Gross Axle Weight Rating (GAWR) of the rear axle. See “Loading Your Vehicle” in the Index.

Page 311 Tires Your new vehicle comes with high a leading tire manufacturer. If you ever have questions about your tire warranty and where to obtain service, see your GM Warranty booklet for details. CAUTION: Poorly maintained and improperly used tires are dangerous. Overloading your tires can cause overheating as a result of too much friction.
Page 312 Inflation -- Tire Pressure The Certification/Tire label, which is on the driver’s door edge, above the door latch, 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.
Page 313: Tire Inspection And Rotation
Tire Inspection and Rotation Tires should be rotated every 6,000 to 8,000 miles (10 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels.
Page 314 If your vehicle has a compact spare tire, don’t include it in your tire rotation. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Certification/Tire label. Make certain that all wheel nuts are properly tightened.
Page 315: Buying New Tires
Buying New Tires To find out what kind and size of tires you need, look at the Certification/Tire label. The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) number on each tire’s sidewall. When you get new tires, get ones with that same TPC Spec number.
Page 316: Uniform Tire Quality Grading
Uniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A 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.
Page 317: Wheel Replacement
Temperature A, B, C The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure.
Page 318 Each new wheel should have the same load capacity, diameter, width, offset and be mounted the same way as the one it replaces. If you need to replace any of your wheels, wheel bolts or wheel nuts, replace them only with new GM original equipment parts.
Page 319: Tire Chains
Tire Chains NOTICE: If your vehicle has P235/75R15, P235/70R15, P235/55R16 or 31x10.50R15LT/C 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.
Page 320: Appearance Care
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.
Page 321: Special Fabric Cleaning Problems
Here are some cleaning tips: Always read the instructions on the cleaner label. Clean up stains as soon as you can Carefully scrape off any excess stain. Use a clean cloth or sponge, and change to a clean area often. A soft brush may be used if stains are stubborn. If a ring forms on fabric after spot cleaning, clean the entire area immediately or it will set.
Page 322: Cleaning Vinyl
Cleaning Vinyl Use warm water and a clean cloth. Rub with a clean, damp cloth to remove dirt. You may have to do it more than once. Things like tar, asphalt and shoe polish will stain if you don’t get them off quickly. Use a clean cloth and a vinyl/leather cleaner.
Page 323: Cleaning Glass Surfaces
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. Don’t use abrasive cleaners on glass, because they may cause scratches.
Page 324: Finish Care
All cleaning agents should be flushed promptly and not allowed to dry on the surface, or they could stain. Dry the finish with a soft, clean chamois or an all towel to avoid surface scratches and water spotting. High pressure car washes may cause water to enter your vehicle.
Page 325: Cleaning Aluminum Wheels
