Page 14 Seats and Seat Controls This section tells about the seats them and fold them up and down. It also tells reclining front seatbacks and head restraints. Manual Front Seat You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is moving.
Page 15 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 To raise the seat, move the knob up.
Page 16 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 seat. Move the switch forward to MED or HIGH temperature to turn on the heating elements in the seat, The right front passenger’s safety belt must be buckled before the heating elements in that seat will operate.
Page 17 But don’t have a seatback reclined if your vehicle is moving. 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 (2-Door Utility) the seatback isn’t locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked. The front seatback folds forward to let you access the rear of the vehicle.
Page 19 Easy Entry Seat (2-Door Utility) 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 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 20 Rear Seats 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 21 To fold the seat, pull on the release handle at the bottom When you release the seat cushion, the seatback is of the seat cushion marked RELEASE. automatically released. Pull the loop on the seatback forward and fold the seatback onto the seat cushion.
Page 22 While the seat is in the folded position, hang the latch plate end of the outer passenger position safety belts on the hooks at the top of each retractor cover, out of the way. To return the seat to the passenger position, just lift up on the seatback and push it rearward until it latches.
Page 23 To fold the seat, pull up on Then, pull the seat cushion up and fold it forward. After folding the seat cushion fully forward, pull the seatback forward and fold the seatback down until it is flat. Then, stow the head restraints by sliding them into the rear of the seatback.
Page 24 Folding the Second Seat (Suburban) If your vehicle has a 60/40 rear 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. That way, the center safety belt will be out of the way when the seat is folded and also will be easily available for passengers to use when the seat is returned to the passenger position.
Page 25 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, lift the load floor panels and latch them into the seatback. Then lift the rear seatback up and latches.
Page 26 Entry to the Rear Seat (Suburban Second Seat) 60140 split folding bench seat The right side of the rear has an easy entry feature. That makes it easy to get in and out of the third seat, if you have one. To operate the seat, move the lever at the side of the seat down.
Page 27 A safety belt that is twisted or not properly attached won’t provide the protection needed in a crash. The person wearing the belt couId be seriously injured. After installing the seat, always check to be sure that the safety belts are not twisted and are properly attached.
Page 28 Move the seatback release lever, at the right rear of the seat, toward the center of the vehicle. Then, fold the seatback forward into the seat cusnlon. To unlatch the seat from the floor, pull up on the center release handle at the rear of the seat and lift the rear seat Turn the seat sideways and take it out of the vehicle.
Page 29 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 with safety belts. And it explains the air bag system. Don’t let anyone ride where he or she can’t wear a safety belt properly.
Page 30 Your vehicle has a light that comes buckle up. (See “Safety Belt Reminder Light” in the Index.) In most states and Canadian provinces, the law says to wear safety belts. Here’s why: They work. You never know if you’ll be in a crash. If you do have a crash, you don’t know if it will be a bad one.

Page 32 or the instrument panel The person keeps going until stopped by something. In a real vehicle, it could be the windshield 1-20...
Page 33 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 34 If I’m a good driver, and I never drive far from home, why should 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 35 3. Pick up the latch plate and pull the belt across you. Don't let it get twisted. 4. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure If the belt isn't long enough. see "Safety Belt Extender"...
Page 36 Shoulder Belt Height Adjuster Before you begin to drive, move the shoulder belt adjuster to the height that is right for you. 1-24 To move it down, push in at the word the height adjuster to the desired position. You can move the adjuster up just by pushing up guide.
Page 37 What's wrong with this? The shoulder belt is too loose. It won't give nearly as much protection this way. 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 38 What’s wrong with this? The belt is buckled i n the wrong place. 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 39 What’s wrong with this? The belt is over an armrest. 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 40 What's wrong with this? The shoulder belt is worn under the arm. It should be worn over the shoulder at all times. 1-28 You can be seriously injured if you wear the shoulder belt under your arm. In body would move too far forward, which would increase the chance of head and neck injury.
Page 41 &= What’s wrong with this? The belt is twisted across the body. 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 42 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 43 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 44 0 “ ’ D - - - - Air bags inflate h great force, faster than the blink of an eye. If you’re too close to an inflating air bag, it could seriously injure you. Safety belts help keep you in position before and during a crash.
Page 45 There is an air bag readiness light on the instrument AI R 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 46 The right front passenger’s air bag is in the instrument panel on the passenger’s side. 1-34 /r\ CAUr-10N: 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 kept clear.
Page 47 When should an air bag inflate? An air bag is designed to inflate in a moderate to severe frontal or near-frontal crash. The air bag will inflate only if the impact speed is above the system’s designed “threshold level.” If your vehicle goes straight into a wall that doesn’t move or deform, the threshold level is about to 16 mph...
Page 48 What will you see after an air bag inflates? After an air bag inflates, it quickly deflates, so quickly that some people may not even realize the air bag inflated. Some components of the module -- the steering wheel hub for the driver’s air bag, or the instrument panel for the right front passenger’s bag will be hot for a short time.
Page 49 Your vehicle is equipped with diagnostic module, which records information about the air bag system. The module records information about the readiness of the system, when the sensors are activated and driver‘s safety belt usage at deployment. Let only qualified technicians work on your air bag system.
Page 50 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 struct.ure isn’t changed, it’s not likely to keep the air bags from working properly in a crash.
Page 51 When you sit in a center seating position, you have a lap safety which has no retractor. To make the belt 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 52 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 58 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. When installed on a shoulder belt, the comfort guide pulls the belt away from the neck and head.

Page 61 Smaller Children and Babies Children who are up against, or very close to, an air bag when it inflates be seriously injured or killed. Air bags plus lap-shoulder belts offer the best 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 62 Infants need complete support, including support for the head and neck. This is necessary because an infant’s neck is weak and its head weighs so much compared with the rest of body. In a crash, an infant in rear-facing restraint settles into the restraint, so the crash forces can be distributed across the strongest part of the infant’s body, the back and shoulders.
Page 63 at only 25 mph (40 km/h), a 12-lb. (5.5 kg) baby will suddenly become a 240-lb. (110 kg) force on your arms. The baby would be almost impossible to hold. Secure the baby in an infant restraint. Child Restraints Every time infants and young children ride in vehicles, they should have protection provided by appropriate restraints.
Page 64 Some infant seats come in two parts -- the base secured in the vehicle and the seat part is removable. A forward-facing child restraint positions a child upright face forward the vehicle. These forward-facing restraints are designed to help protect children who are from 20 to 40 Ibs. (9 to 18 kg) and about 26 to 40 inches (66 to 102 cm) in height, or up to around four years a convertible restraint, is...
Page 65 A child in a rear-facing child restraint can be seriously injured if the right front passenger’s air bag inflates. This is because the back of a rear-facing child restraint would be very close to the inflating air bag. Always secure a rear-facing child restraint in a rear seat.
Page 66 Securing a Child Restraint in a Rear Outside Seat Position You’ll be using the lap-shoulder belt. See the earlier part about the top strap if the child restraint has one. Be sure to follow the instructions that came with the child restraint.
Page 67 4. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 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 68 You’ll be using the lap belt. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions See the earlier part about the top strap if the child restraint has one.
Page 69 4. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 5. To tighten the belt, pull its free end while you push down on the child restraint.

Page 75 CAUTION: Never do this. Here a child is sitting in a seat that has a lap-shoulder belt, but the shoulder part is behind the child. If the child wears the belt in this way, in a crash the child might slide under the belt. The belt’s force would then be applied right on the child’s abdomen.
Page 76 Checking Your Restraint Systems Now and then, make sure the safety belt reminder light your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired.

Page 194 Defensive Driving The best advice anyone can give about driving is: Drive defensively. Please start with a vesy important safety device vehicle: Buckle up. (See "Sakty Belts" i n the Indcx.) Defensive driving really means '*be ready for anything. On city streets. rural roads or freeways. "always expect the unexpected."...
Page 195 Police records show that almost half of all motor vehicle-related deaths involve alcohol. In most cases, these deaths are the result of someone who was drinking and driving. In recent years, over 17,000 annual motor vehicle-related deaths have been associated with the use of alcohol, with more than 300,000 people injured.
Page 196 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 197 Drinking and then driving is very dangerous. Your reflexes, perceptions, attentiveness and judgment can be affected by even a small amount of alcohol. You can have a serious fatal collision if you drive after drinking. Please don’t drink and drive or ride with a driver who has been drinking.
Page 198 Braking action involves perception time and recrctior? time. First, you have to decide to push on the brake pedal. That’s perception tir~e. Then you have to bring up your foot and do it. That’s rccrction time. Average reaction time is about 3/4 of a second. But that‘s only an average.
Page 199 Anti-Lock Brakes (ABS) Your vehicle has anti-lock brakes (ABS). ABS is an advanced electronic braking system that will help prevent a braking skid. When you start your engine and begin to drive away. your anti-lock brake system will check itself. You may hear momentary motor or clicking noise while this test is going on.
Page 200 The anti-lock system can change the brake pressure faster than any driver could. The computer is programmed to make the most of available tire and road conditions. You can steer around the obstacle while braking hard. As you brake, your computer keeps receiving updates on wheel speed and controls braking pressure accordingly.
Page 201 Steering Power Steering If you lose power steering assist because the engine stops or the system is not fi~nctioning, you can steer but it will take much more effort. Speed Sensitive Steering This system varies the amount of steering effort proportionate to your vehicle speed.
Page 202 Steering in Emergencies There are times when steering can be more effective than braking. For example, you come over a hill and find a truck stopped in your lane, or a car suddenly pulls out from nowhere, or a child darts out from between parked cars and stops right in front of you.
Page 203 Off-Road Recovery You may find that your right wheels have dropped off the edge of a road onto the shoulder while you're driving. v / / / edge o f paved surface If the level of the shoulder is only slightly below the pavement, recovery should be fairly easy.
Page 204 Do not get too close to the vehicle you want pass while you’re awaiting an opportunity. For one thing, following t.oo 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 205 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 206 Off-Road Driving with Your Four-Wheel-Drive Vehicle This off-road guide is for vehicles that have four-wheel drive. Also, see "Anti-Lock Brakes" in the Index. If your vehicle doesn't have four-wheel drive: you shouldn't drive off-road unless you're on solid surface. Off-road driving can be great fun. But have some definite hazards.
Page 207 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 208 Traveling to Remote Areas It makes sense to plan your trip, especially when going remote area. Know the terrain and plan your route. You are much less likely to get bad surprises. Get of trails and terrain. Try to learn of any accurate maps blocked or closed roads.
Page 209 Scanning the Terrain Off-road driving can take you over many different kinds of terrain. You need to be familiar with the terrain and its many different features. Here are some things to consider. Surface Conditions. Off-roading can take you over hard-packed dirt, gravel, rocks, grass, sand, mud, snow or ice.
Page 210 Driving on Off-Road Hills Off-road driving often takes you up, down or across a hill. Driving safely on hills requires good judgment and an understanding of what your vehicle can and can't There are some hills that simply can't be driven, no matter how well built the vehicle.
Page 211 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 your speed.
Page 212 Q.’ What should I do if my vehicle stalls, or is about to stall, and 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 s l ~ o ~ ~ l d Push the brake pedal to stop the vehicle and keep...
Page 213 &= 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) and turn off the engine. Leave the vehicle and go get some help. Exit side and stay clear of the path the vehicle would take if it rolled downhill.
Page 214 Driving Downhill When off-roading takes you downhill, you'll want to consider a number of things: Will I be able How steep is the d o w ~ ~ h i l l ? vehicle control? What's the surface like? Smooth? Rough? Slippery? Hard-packed dirt? Gravel? Are there hidden surface obstacles'? Ruts:' Logs'? Boulders?
Page 215 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 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 216 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 too steep to drive across.
Page 217 What if I’m driving across an incline that’s not too steep, but hit some loose gravel and start to slide downhill. What should I do? If you feel your vehicle starting to slide sideways, turn downhill. This should help straighten out the vehicle and prevent the side slipping.
Page 218 Driving in Mud, Sand, Snow or Ice you drive When i n mud, snow or sand, your wheels won’t get good traction. You can’t accelerate as quickly, turning is more difficult, and you’ll need longer braking distances. It’s best. to use a low gear when you’re i n mud -- the deeper the mud, the lower the gear.
Page 219 If the water isn’t too deep, then drive through it slowly. At fast speeds, water splashes on your ignition system and your vehicle can stall. Stalling can also occur if you get y o ~ ~ r tailpipe under water. And, tailpipe is under water, you’ll never be able engine.
Page 220 Driving at Night Night driving is more dangerous than day driving. One reason is that some drivers are likely to be impaired by alcohol or drugs, with night vision problems, or fatigue. Here are some tips on night driving. Drive defensively. Don't drink and drive.
Page 221 Night Vision No one can see as well at night as in the daytime. But we get older these differences increase. A 50-year-old driver may require at least twice as much light to see the same thing at night as a 20-year-old. What you do in the daytime can also affect your night vision.
Page 222 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 your tire-to-road traction isn't as good as on dry roads. 4-30 And, if your tires don't have much tread left, you'll get even less traction.
Page 223 fdst through large water puddles or even Driving going through some car washes can cause problems, too. may affect your brakes. Try to avoid puddles. The water But if you can't, try to slow down before you hit them. Wet brakes can cause accidents. They won't work as well in a quick stop and may cause pulling to one side.
Page 224 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.
Page 225 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 i n city driving: Know the best way to get to where you are going.
Page 226 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. 4-34 The most important advice on freeway driving is: Keep with traffic and keep to the right. Drive L ~ I speed most of the other drivers are driving.
Page 227 When you want to leave the freeway, move to the proper lane well i n advance. I f you miss your exit, do not, under any circumstances. stop and back up. Drive on to the next exit. The exit ramp can be curved, sonletimes quite sharply. The exit speed is usually posted.
Page 228 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 h u m 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 229 If you drive regularly in steep country, or if you're planning to visit there, here are some tips that can make your trips safer and more enjoyable. (See "Off-Road Driving" in the Index for information about driving off-road.) Keep your vehicle in good shape. Check all fluid levels and also the brakes, tires, cooling system and transmission.
Page 230 Wi-nter Driving Here at-e some tips for winter driving: Have your vehicle in good shape for winter. You may want to put winter emergency supplies your vehicle. 4-38 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, reflective warning triangles.
Page 231 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 232 If You're Caught in a Blizzard If you are stopped by heavy snow, you could be in serious situation. You should probably stay with your vehicle unless you know for sure that you are near help and you can hike tlvough the snow. Here are some things to do sunlmon help and keep yourself and your passengers safe:...
