  • Page 8: Seats And Seat Controls

    Seats and Seat Controls This section tells you about the seats them and fold them up and down. It also tells you about reclining front seatbacks and head restraints. Manual Front Seat CAUTION: You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is moving.
  • Page 9: Power Seats - If Equipped

    Power Seat(s) (If Equipped) If your vehicle has a power seat on the driver’s or passenger’s side, you can adjust it with these controls at the outside edge of the seat. The switch is located on the side of the seat, next to the door. You can use the round center knob to move the seat to where you want it.
  • Page 10: Reclining Front Seatbacks

    Heated Front Seats (If Equipped) The control for the driver’s side heated seat is located on the left side of the seat. The control for the right front passenger is located on the right side of the passenger’s seat. Move the switch forward to MED or HIGH temperature to turn on the heating elements in the seat.
  • Page 11 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 12: Head Restraints

    Head Restraints Slide the head restraint up or down so that the top of the restraint is closest to the top of your ears. This position reduces the chance of a neck injury in a crash. Seatback Latches (2-Door Utility) CAUTION: If the seatback isn’t locked, it could move forward in a sudden stop or crash.
  • Page 13 Easy Entry Seat (2-Door Utility) CAUTION: If any easy entry seat isn’t locked, it can move. In a sudden stop or crash, the person sitting there could be injured. And, even if there is no crash or sudden stop, a driver sitting in an unlocked easy entry seat could be startled by the sudden movement and hit the wrong control or pedal, causing an accident.
  • Page 14: Rear Seats

    Rear Seats CAUTION: If a head restraint is not installed on the seatback or stored in the vehicle properly, it could be thrown about the vehicle in a crash or sudden maneuver. People in the vehicle could be injured. Remove the head restraints only when you need to fold the seat, and be sure that the head restraints are stored securely in the storage bag and placed under the rear seat.
  • Page 15 To fold the seat, pull on the release handle at the bottom of the seat cushion marked RELEASE. When you release the seat cushion, the seatback is automatically released. Pull the loop on the seatback forward and fold the seatback onto the seat cushion. To return the seat to the passenger position, just lift up on the seatback and push it rearward until it latches.
  • Page 16 Folding Rear Seats (4 Door Models) The rear seat of the 4 Door Utility or the second seat of a Suburban may have a 60/40 seat, either side may be folded down to give you more cargo space. Before folding, place the latch portion of the center safety belt in the center armrest.
  • Page 17 On Suburban models, to create a load floor, release the panels from the seatback by pushing rearward on the latch and fold them out to cover the rear seat footwell. To return the seat to the passenger position on a Suburban, lift the load floor panels and latch them into the seatback.
  • Page 18 There is a foot release lever for rear seat passengers to use when getting out of the third seat. To release the easy entry second seat, lift up on the top of the release lever with your foot. Push the top of the seatback forward and tilt it toward the front of the vehicle.
  • Page 19 Then, hang the latch plate end of the belt on the hook at the top of the retractor cover, out of the way. To remove the seat, fully open the rear load doors and enter the back of the vehicle. Move the seatback release lever, at the right rear of the seat, toward the center of...
  • Page 20: Safety Belts: They're For Everyone

    CAUTION: A safety belt that is twisted or not properly attached won’t provide the protection needed in a crash. The person wearing the belt could be seriously injured. After installing the seat, always check to be sure that the safety belts are not twisted and are properly attached.
  • Page 21: Why Safety Belts Work

    CAUTION: It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, people riding in these areas are more likely to be seriously injured or killed. Do not allow people to ride in any area of your vehicle that is not equipped with seats and safety belts.

  • Page 25: Here Are Questions Many People Ask

    Here Are Questions Many People Ask About Safety Belts and the Answers Won’t I be trapped in the vehicle after an accident if I’m wearing a safety belt? You could be whether you’re wearing a safety belt or not. But you can unbuckle a safety belt, even if you’re upside down.
  • Page 26: How To Wear Safety Belts Properly

    How to Wear Safety Belts Properly Adults This part is only for people of adult size. Be aware that there are special things to know about safety belts and children. And there are different rules for smaller children and babies. If a child will be riding in your vehicle, see the part of this manual called “Children.”...
  • Page 27 yellowblue 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 Shoulder Belt Height Adjuster Before you begin to drive, move the shoulder belt adjuster to the height that is right for you. 1-22 To move it down, push in at the word PRESS and move the height adjuster to the desired position. You can move the adjuster up just by pushing up on the shoulder belt guide.
  • Page 29 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 30 What’s wrong with this? The belt is buckled in the wrong place. 1-24 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 31 What’s wrong with this? The belt is over an armrest. CAUTION: You can be seriously injured if your belt goes over an armrest like this. The belt would be much too high. In a crash, you can slide under the belt. The belt force would then be applied at the abdomen, not at the pelvic bones, and that could cause serious or fatal injuries.
  • Page 32 What’s wrong with this? The shoulder belt is worn under the arm. It should be worn over the shoulder at all times. 1-26 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 33 What’s wrong with this? The belt is twisted across the body. 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 34: 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 35: 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 36 CAUTION: Air bags inflate with great force, faster than the blink of an eye. If you’re too close to an inflating air bag, it could seriously injure you. This is true even with Next Generation frontal air bags. Safety belts help keep you in position before and during a crash.
  • Page 37: How The Air Bag System Works

    There is an air bag readiness light on the instrument panel, which shows AIR BAG. The system checks the air bag electrical system for malfunctions. The light tells you if there is an electrical problem. See “Air Bag Readiness Light” in the Index for more information.
  • Page 38 The right front passenger’s air bag is in the instrument panel on the passenger’s side. 1-32 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.
  • Page 39 In any particular crash, no one can say whether an air bag should have inflated simply because of the damage to a vehicle or because of what the repair costs were. Inflation is determined by the angle of the impact and how quickly the vehicle slows down in frontal or near frontal impacts.
  • Page 40 CAUTION: When an air bag inflates, there is dust in the air. This dust could cause breathing problems for people with a history of asthma or other breathing trouble. To avoid this, everyone in the vehicle should get out as soon as it is safe to do so. If you have breathing problems but can’t get out of the vehicle after an air bag inflates, then get fresh air by opening a window or door.
  • Page 41: Servicing Your Air Bag-Equipped Vehicle

    If your vehicle ever gets into a lot of water water up to the carpeting or higher your vehicle and soaks the carpet, the air bag controller can be soaked and ruined. If this ever happens, and then you start your vehicle, the damage could make the air bags inflate, even if there’s no crash.
  • Page 42: Adding Equipment To Your Airbag-Equipped Vehicle

    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 43 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 44: Rear Seat Outside Passenger Positions

    Rear Seat Passengers It’s very important for rear seat passengers to buckle up! Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts. Rear passengers who aren’t safety belted can be thrown out of the vehicle in a crash.
  • Page 45 When the shoulder belt is pulled out all the way, it will lock. If it does, let it go back all the way and start again. If the belt is not long enough, see “Safety Belt Extender” at the end of this section. 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 46 Four door utility models and the second seat of Suburbans have shoulder belt height adjusters. Move the shoulder belt height adjuster to the height that is right for you. 1-40 To move the height adjuster down, push in at the word PRESS and move the height adjuster to the desired position.
  • Page 47: Rear Safety Belt Comfort Guides For Children And Small Adults

    To unlatch the belt, just push the button on the buckle. Rear Safety Belt Comfort Guides for Children and Small Adults Your vehicle may have rear shoulder belt comfort guides. This feature will provide added safety belt comfort for children who have outgrown child restraints and for small adults.
  • Page 48 2. Slide the guide under and past the belt. The elastic cord must be under the belt. Then, place the guide over the belt, and insert the two edges of the belt into the slots of the guide. 1-42 3. Be sure that the belt is not twisted and it lies flat. The elastic cord must be under the belt and the guide on top.
  • Page 49: Smaller Children And Babies

    4. Buckle, position and release the safety belt as described in “Rear Seat Outside Passenger Positions” earlier in this section. Make sure that the shoulder belt crosses the shoulder. To remove and store the comfort guides, squeeze the belt edges together so that you can take them out from the guides.
  • Page 50 CAUTION: Smaller children and babies should always be restrained in a child or infant restraint. The instructions for the restraint will say whether it is the right type and size for your child. A very young child’s hip bones are so small that a regular belt might not stay low on the hips, as it should.
  • Page 51 CAUTION: Never hold a baby in your arms while riding in a vehicle. A baby doesn’t weigh much crash. During a crash a baby will become so heavy you can’t hold it. For example, in a crash CAUTION: (Continued) CAUTION: (Continued) at only 25 mph (40 km/h), a 12 will suddenly become a 240 your arms.
  • Page 52: Child Restraints

    Child Restraints Every time infants and young children ride in vehicles, they should have protection provided by appropriate restraints.

When selecting a child restraint, take into consideration not only the child’s weight and size, but also whether or not the restraint will be compatible with the motor vehicle in which it will...
  • Page 53 yellowblue A rear facing infant restraint (B) positions an infant to face the rear of the vehicle. Rear facing infant restraints are designed for infants of up to about 20 lbs. (9 kg) and about one year of age. This type of restraint faces the rear so that the infant’s head, neck and body can have the support they need in a frontal crash.
  • Page 54 yellowblue A forward facing child restraint (C E) positions a child upright to face forward in the vehicle. These forward facing restraints are designed to help protect children who are from 20 to 40 lbs. (9 to 18 kg) and about 26 to 40 inches (66 to 102 cm) in height, or up to around four years of age.
  • Page 55 yellowblue A booster seat (F, G) is designed for children who are about 40 to 60 lbs., or even up to 80 lbs. (18 to 27 kg, or even up to 36 kg), and about four to eight years of age. A booster seat is designed to improve the fit of the vehicle’s safety belt system.
  • Page 56: Where To Put The Restraint

    When choosing a child restraint, be sure the child restraint is designed to be used in a vehicle. If it is, it will have a label saying that it meets Federal Motor Vehicle Safety Standards. Then follow the instructions for the restraint. You may find these instructions on the restraint itself or in a booklet, or both.
  • Page 57: Top Strap

    Top Strap If your child restraint has a top strap, it should be anchored. Suburban models: If you need to have an anchor bracket installed for a second row seat or a center rear seat, you can ask your dealer to put it in for you. If you want to install the anchor yourself, your dealer can tell you how to do it.

  • Page 185: 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 186 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 187 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 188: 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 189: 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 190 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. 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 191: Braking In Emergencies

    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 192: Steering In Emergencies

    Experienced driver or beginner, each of us is subject to the same laws of physics when driving on curves. The traction of the tires against the road surface makes it possible for the vehicle to change its path when you turn the front wheels.
  • Page 193 An emergency like this requires close attention and a quick decision. If you are holding the steering wheel at the recommended 9 and 3 o’clock positions, you can turn it a full 180 degrees very quickly without removing either hand. But you have to act fast, steer quickly, and just as quickly straighten the wheel once you have avoided the object.
  • Page 194 Passing The driver of a vehicle about to pass another on a lane highway waits for just the right moment, accelerates, moves around the vehicle ahead, then goes back into the right lane again. A simple maneuver? Not necessarily! Passing another vehicle on a two highway is a potentially dangerous move, since the passing vehicle occupies the same lane as oncoming traffic for several seconds.
  • Page 195: Loss Of Control

    Check your mirrors, glance over your shoulder and start your left lane change signal before moving out of the right lane to pass. When you are far enough ahead of the passed vehicle to see its front in your inside mirror, activate your right lane change signal and move back into the right lane.
  • Page 196: Off - Road Driving With Your Four - Wheel - Drive Vehicle

    Of course, traction is reduced when water, snow, ice, gravel or other material is on the road. For safety, you’ll want to slow down and adjust your driving to these conditions. It is important to slow down on slippery surfaces because stopping distance will be longer and vehicle control more limited.

    Controlling your vehicle is the key to successful road driving. One of 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.
  • Page 200: Driving On Off-Road Hills

    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 over bumps, rocks, or other obstacles, your wheels can leave the ground.

Here are some other things to consider as you approach a hill. Is there a constant incline, or does the hill get sharply steeper in places? Is there good traction on the hillside, or will the...
  • Page 202 Ease up on your speed as you approach the top of the hill. Attach a flag to the vehicle to make you more visible to approaching traffic on trails or hills. Sound the horn as you approach the top of the hill to let opposing traffic know you’re there.
  • Page 203 As you are backing down the hill, put your left hand on the steering wheel at the 12 o’clock position. This way, you’ll be able to tell if your wheels are straight and maneuver as you back down. It’s best that you back down the hill with your wheels straight rather than in the left or right direction.
  • Page 204: Driving Downhill

    Driving Downhill When off roading takes you downhill, you’ll want to consider a number of things: How steep is the downhill? Will I be able to maintain vehicle control? What’s the surface like? Smooth? Rough? Slippery? Hard packed dirt? Gravel? Are there hidden surface obstacles? Ruts? Logs? Boulders? What’s at the bottom of the hill? Is there a hidden...
  • Page 205: Driving Across An Incline

    Am I likely to stall when going downhill? It’s much more likely to happen going uphill. But if it happens going downhill, here’s what to do. Stop your vehicle by applying the regular brakes. Apply the parking brake. Shift to PARK (P) and, while still braking, restart the engine.
  • Page 206: Stalling On An Incline

    Hidden obstacles can make the steepness of the incline even worse. If you drive across a rock with the uphill wheels, or if the downhill wheels drop into a rut or depression, your vehicle can tilt even more. For reasons like these, you need to decide carefully whether to try to drive across an incline.
  • Page 207: Driving In Mud, Sand, Snow Or Ice

    CAUTION: Getting out on the downhill (low) side of a vehicle stopped across an incline is dangerous. If the vehicle rolls over, you could be crushed or killed. Always get out on the uphill (high) side of the vehicle and stay well clear of the rollover path. Driving in Mud, Sand, Snow or Ice When you drive in mud, snow or sand, your wheels won’t get good traction.
  • Page 208: Driving In Water

    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 209: After Off-Road Driving

    CAUTION: Driving through rushing water can be dangerous. Deep water can sweep your vehicle downstream and you and your passengers could drown. If it’s only shallow water, it can still wash away the ground from under your tires, and you could lose traction and roll the vehicle over.
  • Page 210: Driving At Night

    Driving at Night Night driving is more dangerous than day driving. One reason is that some drivers are likely to be impaired alcohol or drugs, with night vision problems, or by fatigue. 4-28 Here are some tips on night driving. Drive defensively.
  • Page 211: Night Vision

    Night Vision No one can see as well at night as in the daytime. But as we get older these differences increase. A 50 driver may require at least twice as much light to see the same thing at night as a 20 year old.
  • Page 212: Driving In Rain And On Wet Roads

    yellowblue 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 213 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 214: Driving Through Deep Standing Water

    Hydroplaning Hydroplaning is dangerous. So much water can build up under your tires that they can actually ride on the water. This can happen if the road is wet enough and you’re going fast enough. When your vehicle is hydroplaning, it has little or no contact with the road.

    NOTICE: When using concentrated washer fluid, follow the manufacturer’s instructions for adding water. Don’t mix water with ready fluid. Water can cause the solution to freeze and damage your washer fluid tank and other parts of the washer system. Also, water doesn’t clean as well as washer fluid.
  • Page 311 So, it isn’t a good idea to “top off” your brake fluid. Adding brake fluid won’t correct a leak. If you add fluid when your linings are worn, then you’ll have too much fluid when you get new brake linings. You should add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system.
  • Page 312 What to Add When you do need brake fluid, use only DOT fluid. Refer to “Recommended Fluids and Lubricants” in the Index. Use new brake fluid from a sealed container only. Always clean the brake fluid reservoir cap and the area around the cap before removing it.
  • Page 313: Brake Wear

    Brake Wear Your vehicle has front disc brakes and rear drum 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).
  • Page 314: Fluid Leak Check

    Brake Adjustment Every time you make a brake stop, your disc brakes adjust for wear. If your brake pedal goes down farther than 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.

    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 324: Tire Inspection And Rotation

    NOTICE: Don’t let anyone tell you that underinflation or overinflation is all right. It’s not. If your tires don’t have enough air (underinflation), you can get the following: Too much flexing Too much heat Tire overloading Bad wear Bad handling Bad fuel economy.
  • Page 325 When rotating your tires, always use one of the correct rotation patterns shown here. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Certification/Tire label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” in the Index.
  • Page 326: Buying New Tires

    When It’s Time for New Tires One way to tell when it’s time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining. You need a new tire if any of the following statements are true: You can see the indicators at three or more places around the tire.
  • Page 327: Uniform Tire Quality Grading

    CAUTION: Mixing tires could cause you to lose control while driving. If you mix tires of different sizes or types (radial and bias belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes may also cause damage to your vehicle.
  • Page 328: Wheel Alignment And Tire Balance

    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. For example, a tire graded 150 would wear one and a half (1 1/2) times as well on the government course as a tire graded 100.
  • Page 329: Wheel Replacement

    Wheel Replacement Replace any wheel that is bent, cracked, or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired).
