Page 9: Front Seats
Front Seats Manual Seats CAUTION: You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you do not want to.
Page 10 Power Seats If you have this feature, the power seat controls are located on the outboard side of the front seat cushions. The horizontal control adjusts the seat cushion and the vertical control adjusts the seatback. • Move the front of the seat control up or down to adjust the front portion of the cushion.
Page 11: Manual Lumbar
Manual Lumbar If your vehicle has this feature, there is a knob located on the outboard side of the driver’s seat. Turn the knob counterclockwise to increase lumbar support and clockwise to decrease lumbar support. Power Lumbar Your vehicle may have this feature. The control is located on the outboard side of the seat cushion.
Page 12: Heated Seats
Heated Seats Your vehicle may have heated front seats. The buttons used to control this feature are located on the front door armrests. The engine must be running for the heated seat feature to work. To heat the entire seat, press the horizontal button with the heated seat symbol.
Page 13: Reclining Seatbacks
Reclining Seatbacks If your vehicle has a manual recliner, lift the lever located on the outboard side of the seat and push the seatback rearward to recline the seatback. To return the seatback to the normal position, lift the lever without pushing rearward on the seatback and the seatback will move forward.
Page 14 But do not 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 cannot do their job when you are reclined like this. The shoulder belt cannot do its job.
Page 15: Rear Seats
Head Restraints Adjust your head restraint so that the top of the restraint is closest to the top of your head. This position reduces the chance of a neck injury in a crash. The head restraints lock into place when raised. To release the head restraint and lower it, press the tab located on the top of the seatback.
Page 16 The rear seatback levers are located on the outboard side of the rear seatbacks. Pull the seatback toward you as you lift up on the lever. The head restraint will automatically fold out of the way when the seatback is folded down. To raise the seatbacks, lift up the seatbacks and push on them until they lock into the upright position.
Page 17 Envoy XL and Envoy XL Denali The second row seat is a 65/35 split seat which may be folded and tumbled. Use this feature for gaining access to the third row seats. To fold and tumble the second row seat(s), do the following: 1.
Page 18 Folding the Third Row Seats 1. Pull up on the handle located on the bottom of the seat cushion to release the seat cushion. 2. Lift up the seat, and then pull it forward. 3. Fold the seatback forward until it is ﬂat. 4.
Page 19 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 20: Why Safety Belts Work
Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. Put someone on it. Take the simplest vehicle. Suppose it is just a seat on wheels. 1-14...
Page 21 Get it up to speed. Then stop the vehicle. The rider does not stop. The person keeps going until stopped by something. In a real vehicle, it could be the windshield... 1-15...
Page 22 or the instrument panel... 1-16 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 is why safety belts make such good sense.
Page 23 Questions and Answers About Safety Belts Will I be trapped in the vehicle after an accident if I am wearing a safety belt? You could be — whether you are wearing a safety belt or not. But you can unbuckle a safety belt, even if you are upside down.
Page 24 How to Wear Safety Belts Properly 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 Older Children on page 1-31 or Infants and Young Children on page 1-34.
Page 25 5. To make the lap part tight, pull up on the shoulder belt. 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 would be less likely to slide under the lap belt.
Page 26 What is wrong with this? The shoulder belt is too loose. It will not give nearly as much protection this way. 1-20 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 27 What is wrong with this? The belt is buckled in the wrong place. 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 28 What is wrong with this? The shoulder belt is worn under the arm. It should be worn over the shoulder at all times. 1-22 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 29 What is wrong with this? The belt is twisted across the body. CAUTION: You can be seriously injured by a twisted belt. In a crash, you would not 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 30 Safety Belt Use During Pregnancy Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they do not wear safety belts. A pregnant woman should wear a lap-shoulder belt, and the lap portion should be worn as low as possible, below the rounding, throughout the pregnancy.
Page 31 Lap-Shoulder Belt All rear seat positions have lap-shoulder belts. Here is how to wear one properly. 1. Pick up the latch plate and pull the belt across you. Do not let it get twisted. The shoulder belt may lock if you pull the belt across you very quickly.
Page 32 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 would be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen.
Page 33: Rear Safety Belt Comfort Guides For Children And Small Adults
Rear Safety Belt Comfort Guides for Children and Small Adults Rear shoulder belt comfort guides may provide added safety belt comfort for older children who have outgrown booster seats and for some adults. When attached to a shoulder belt, the comfort guide positions the belt away from the neck and head.
Page 34 3. Your comfort guide may have an adjuster to lengthen or shorten the cord. If it does, you can adjust the cord by following these steps. 3.1. Squeeze and hold the ends of the lock (A) on the elastic cord. 3.2.
Page 35 CAUTION: A safety belt that is not properly worn may not provide the protection needed in a crash. The person wearing the belt could be seriously injured. 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.
Page 36 Safety Belt Pretensioners Your vehicle has safety belt pretensioners for the driver and right front passenger. Although you cannot see them, they are located on the retractor part of the safety belts. They help the safety belts reduce a person’s forward movement in a moderate to severe frontal, near frontal or side crash or a rollover.
Page 37: Safety Belts
Child Restraints Older Children Older children who have outgrown booster seats should wear the vehicle’s safety belts. What is the proper way to wear safety belts? An older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide.
Page 38 CAUTION: Never do this. Here two children are wearing the same belt. The belt can not 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. 1-32 What if a child is wearing a lap-shoulder belt, but the child is so small that the shoulder belt...
Page 39 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.
Page 40 Infants and Young 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 41: Child Restraints
CAUTION: Children who are up against, or very close to, any airbag when it inﬂates can be seriously injured or killed. Airbags plus lap-shoulder belts offer protection for adults and older children, but not for young children and infants. CAUTION: (Continued) CAUTION: (Continued) Neither the vehicle’s safety belt system nor its airbag system is designed for them.
Page 42 The restraint manufacturer’s instructions that come with the restraint state the weight and height limitations for a particular child restraint. In addition, there are many kinds of restraints available for children with special needs. CAUTION: Newborn infants need complete support, including support for the head and neck.
Page 43: Child Restraint Systems
Child Restraint Systems 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 44 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-like shields. 1-38 A booster seat (F-G) is a child restraint designed to improve the ﬁt of the vehicle’s safety belt system. Some booster seats have a shoulder belt positioner, and some high-back booster seats have a ﬁve-point harness.
Page 45 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-on child restraint system is a portable one, which is purchased by the vehicle’s owner.
Page 46: Where To Put The Restraint
Where to Put the Restraint Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. General Motors recommends that child restraints be secured in a rear seat, including an infant riding in a rear-facing infant seat, a child riding in a forward-facing child seat and an older child riding in a booster seat.
Page 47: Top Strap
Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle. Be sure to properly secure any child restraint in your vehicle — even when no child is in it. Top Strap Some child restraints have a top strap, or “top tether.”...
Page 48: Top Strap Anchor Location
For 7 passenger vehicles, if the position you are using has an adjustable head restraint, raise the head restraint and route the top strap under it. See Head Restraints on page 1-9. CAUTION: Each top tether bracket is designed to anchor only one child restraint.
Page 49 Seven-passenger Vehicles For seven-passenger vehicles, there is a top strap anchor for each seating position in the second row. The anchors are located at the bottom rear of the seat cushion. Do not secure a child restraint in the right front passenger’s position or in the third row seating positions (if equipped) if a national or local law requires that the top strap be anchored, or if the instructions that...
Page 50: Lower Anchorages And Top Tethers For Children (Latch System)
Lower Anchorages and Top Tethers for Children (LATCH System) Your vehicle has the LATCH system. There are anchors for the outboard seating positions in the second row. This system, designed to make installation of child restraints easier, does not use the vehicle’s safety belts. Instead, it uses vehicle anchors and child restraint attachments to secure the restraints.
Page 51 A. Lower Anchorage B. Lower Anchorage In order to use the LATCH system in your vehicle, you need a child restraint designed for that system. To assist you in locating the lower anchors for this child restraint system, each seating position with the LATCH system has a label on the seatback at each lower anchor position.
Page 52: Securing A Child Restraint Designed For
Securing a Child Restraint Designed for the LATCH System 1. Find the LATCH anchorages for the seating position you want to use, where the bottom of the seatback meets the back of the seat cushion. See Lower Anchorages and Top Tethers for Children (LATCH System) on page 1-44.
Page 53 3. Buckle the belt. Make sure the release button is 4. Pull the rest of the shoulder belt all the way out of positioned so you would be able to unbuckle the the retractor to set the lock. safety belt quickly if you ever had to. 1-47...
Page 54: Securing A Child Restraint In The Center Seat Position
5. To tighten the belt, push down on the child restraint, pull the shoulder portion of the belt to tighten the lap portion of the belt and feed the shoulder belt back into the retractor. If you are 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 55: Securing A Child Restraint In The Right Front Seat Position
Securing a Child Restraint in the Right Front Seat Position Your vehicle has a right front passenger airbag. A rear seat is a safer place to secure a forward-facing child restraint. See Where to Put the Restraint on page 1-40. In addition, your vehicle has a passenger sensing system.
Page 56 There is no top strap anchor at the right front seating position. Do not secure a child seat in this position if a national or local law requires that the top strap be anchored or if the instructions that come with the child restraint say that the top strap must be anchored.
Page 57 5. Pull the rest of the shoulder belt all the way out of 6. To tighten the belt, push down on the child the retractor to set the lock. restraint, pull the shoulder portion of the belt to tighten the lap portion of the belt and feed the shoulder belt back into the retractor.
Page 58: Airbag System
7. Push and pull the child restraint in different directions to be sure it is secure. 8. If the airbag is off, the off indicator in the inside rearview mirror will be lit and stay lit when the key is turned to RUN or START. If a child restraint has been installed and the on indicator is lit, turn the vehicle off.
Page 59 Here are the most important things to know about the airbag system: CAUTION: You can be severely injured or killed in a crash if you are not wearing your safety belt — even if you have airbags. Wearing your safety belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it.
Page 60 CAUTION: Both frontal and roof-mounted airbags inﬂate with great force, faster than the blink of an eye. If you are too close to an inﬂating airbag, as you would be if you were leaning forward, it could seriously injure you. Safety belts help keep you in position for airbag inﬂation before and during a crash.
Page 61: Where Are The Airbags
Where Are the Airbags? The driver’s airbag is in the middle of the steering wheel. The right front passenger’s airbag is in the instrument panel on the passenger’s side. 1-55...
Page 62 If your vehicle has a roof-mounted airbag for the driver and the person seated directly behind the driver, it is located in the ceiling above the side windows. 1-56 If your vehicle has a roof-mounted airbag for the right front passenger and the person directly behind that passenger, it is located in the ceiling above the side windows.
Page 63: When Should An Airbag Inﬂate
CAUTION: If something is between an occupant and an airbag, the bag might not inﬂate properly or it might force the object into that person causing severe injury or even death. The path of an inﬂating airbag must be kept clear. Do not put anything between an occupant and an airbag, and do not attach or put anything on the steering wheel hub or on or near any other...
Page 64 For more severe frontal impacts, full deployment occurs. If the front of your vehicle goes straight into a wall that does not move or deform, the threshold level for the reduced deployment is about 9 to 16 mph (14 to 26 km/h), and the threshold level for a full deployment is about 18 to 25 mph (29 to 40 km/h).
Page 65: What Makes An Airbag Inﬂate
The airbag system is designed to work properly under a wide range of conditions, including off-road usage. Observe safe driving speeds, especially on rough terrain. As always, wear your safety belt. See Off-Road Driving with Your Four-Wheel-Drive Vehicle on page 4-15 for tips on off-road driving. What Makes an Airbag Inﬂate? In an impact of sufficient severity, the airbag sensing system detects that the vehicle is in a crash.
Page 66: What Will You See After An Airbag Inﬂates
What Will You See After an Airbag Inﬂates? After an airbag inﬂates, it quickly deﬂates, so quickly that some people may not even realize the airbag inﬂated. Some components of the airbag module — the steering wheel hub for the driver’s airbag, the instrument panel for the right front passenger’s bag or the ceiling of your vehicle near the side windows —...
Page 67 Your vehicle has a feature that will automatically unlock the doors and turn the interior lamps on when the airbags inﬂate (if battery power is available). You can lock the doors again and turn the interior lamps off by using the door lock and interior lamp controls. In many crashes severe enough to inﬂate an airbag, windshields are broken by vehicle deformation.
Page 68: Passenger Sensing System
Passenger Sensing System Your vehicle has a passenger sensing system for the right front passenger’s position. A passenger airbag status indicator in the rearview mirror will be visible when you turn your ignition key to START or RUN. The words ON and OFF or the symbol for on and off, will be visible on the rearview mirror during the system check.
Page 69 CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inﬂates. This is because the back of the rear-facing child restraint would be very close to the inﬂating airbag. Even though the passenger sensing system is designed to turn off the passenger’s frontal airbag if the system detects a rear-facing child restraint, no system is fail-safe, and...
Page 70 If after reinstalling the child restraint and restarting the vehicle, the on indicator is still lit, check to make sure that the vehicle’s seatback is not pressing the child restraint into the seat cushion. If this happens, slightly recline the vehicle’s seatback and adjust the seat cushion if possible.
Page 71 CAUTION: If the airbag readiness light in the instrument panel cluster ever comes on and stays on, it means that something may be wrong with the airbag system. If this ever happens, have the vehicle serviced promptly, because an adult-size person sitting in the right front passenger’s seat may not have the protection of the frontal airbag.
Page 72: Servicing Your Airbag-Equipped Vehicle
Servicing Your Airbag-Equipped Vehicle Airbags affect how your vehicle should be serviced. There are airbag system parts in several places around your vehicle. You do not want the system to inﬂate while someone is working on your vehicle. Your dealer and the service manual have information about servicing your vehicle and the airbag system.
Page 73: Restraint System Check
Because I have a disability, I have to get my vehicle modiﬁed. How can I ﬁnd out whether this will affect my airbag system? Changing or moving any parts of the front seats, safety belts, the airbag sensing and diagnostic module (located under the driver’s seat), or the inside rearview mirror can affect the operation of the airbag system.
Page 74: Replacing Restraint System Parts
Replacing Restraint System Parts After a Crash CAUTION: A crash can damage the restraint systems in your vehicle. A damaged restraint system may not properly protect the person using it, resulting in serious injury or even death in a crash. To help make sure your restraint systems are working properly after a crash, have them inspected and any necessary replacements made as soon as possible.

Battery Replacement Under normal use, the battery in your remote keyless entry transmitter should last about two years. You can tell the battery is weak if the transmitter will not work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it’s probably time to change the battery.
Page 82: Doors And Locks
Doors and Locks Door Locks CAUTION: Unlocked doors can be dangerous. • Passengers — especially children — can easily open the doors and fall out of a moving vehicle. When a door is locked, the handle will not open it. You increase the chance of being thrown out of the vehicle in a crash if the doors are not locked.
Page 83: Delayed Locking

Page 268: Your Driving, The Road, And Your Vehicle
Your Driving, the Road, and Your Vehicle 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: They Are for Everyone on page 1-12. Defensive driving really means “be ready for anything.”...
Page 269 Many adults — by some estimates, nearly half the adult population — choose never to drink alcohol, so they never drive after drinking. For persons under 21, it is against the law in every U.S. state to drink alcohol. There are good medical, psychological and developmental reasons for these laws.
Page 270 There is a gender difference, too. Women generally have a lower relative percentage of body water than men. Since alcohol is carried in body water, this means that a woman generally will reach a higher BAC level than a man of her same body weight will when each has the same number of drinks.
Page 271: Control Of A Vehicle
CAUTION: 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 — or even fatal — collision if you drive after drinking. Please do not drink and drive or ride with a driver who has been drinking.
Page 272: Anti-Lock Brake System (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 273 Let us say the road is wet and you are driving safely. Suddenly, an animal jumps out in front of you. You slam on the brakes and continue braking. Here is 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 274: Braking In Emergencies
Remember: Anti-lock does not 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 will not have time to apply your brakes if that vehicle suddenly slows or stops.
Page 275 The traction control off symbol on the button will come on under the following conditions: • The Traction Assist System is turned off, either by pressing the on/off button or by turning off the automatic engagement feature of the TAS. •...
Page 276: Power Steering
Locking Rear Axle If your vehicle has this feature, your locking rear axle can give you additional traction on snow, mud, ice, sand or gravel. It works like a standard axle most of the time, but when one of the rear wheels has no traction and the other does, this feature will allow the wheel with traction to move the vehicle.
Page 277: Steering In Emergencies
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 278: Off-Road Recovery
Off-Road Recovery You may ﬁnd that your right wheels have dropped off the edge of a road onto the shoulder while you are 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 279: Loss Of Control
• Do not get too close to the vehicle you want to pass while you are awaiting an opportunity. For one thing, following too closely reduces your area of vision, especially if you are following a larger vehicle. Also, you will not have adequate space if the vehicle ahead suddenly slows or stops.
Page 280 Skidding In a skid, a driver 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.
Page 281 Off-Road Driving with Your Four-Wheel-Drive Vehicle This off-road guide is for vehicles that have four-wheel drive. Also, see Braking on page 4-5. If your vehicle does not have four-wheel drive, you should not drive off-road unless you are on a level, solid surface. Off-road driving can be great fun.
Page 282 Loading Your Vehicle for Off-Road Driving There are some important things to remember about how to load your vehicle. • The heaviest things should be on the load ﬂoor and forward of your rear axle. Put heavier items as far forward as you can.
Page 283: Environmental Concerns
Environmental Concerns Off-road driving can provide wholesome and satisfying recreation. However, it also raises environmental concerns. We recognize these concerns and urge every off-roader to follow these basic rules for protecting the environment: • Always use established trails, roads and areas that have been specially set aside for public off-road recreational driving;...
Page 284: Scanning The Terrain
Controlling your vehicle is the key to successful off-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 285: 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 are not prepared. When you drive over bumps, rocks, or other obstacles, your wheels can leave the ground.
Page 286: Approaching A Hill
Approaching a Hill When you approach a hill, you need to decide if it is one of those hills that is just too steep to climb, descend or cross. Steepness can be hard to judge. On a very small hill, for example, there may be a smooth, constant incline with only a small change in elevation where you can easily see all the way to the top.
Page 287 • Sound the horn as you approach the top of the hill to let opposing traffic know you are there. • Use your headlamps even during the day. They make you more visible to oncoming traffic. CAUTION: Driving to the top (crest) of a hill at full speed can cause an accident.
Page 288 Here are some things you must not do if you stall, or are about to stall, when going up a hill. • Never attempt to prevent a stall by shifting into NEUTRAL (N) to rev-up the engine and regain forward momentum. This will not work. Your vehicle will roll backwards very quickly and you could go out of control.
Page 289: Driving Downhill
Driving Downhill When off-roading takes you downhill, you will want to consider a number of things: • How steep is the downhill? Will I be able to maintain vehicle control? • What is the surface like? Smooth? Rough? Slippery? Hard-packed dirt? Gravel? •...
Page 290: Driving Across An Incline
Am I likely to stall when going downhill? It is much more likely to happen going uphill. But if it happens going downhill, here is what to do. 1. Stop your vehicle by applying the regular brakes. Apply the parking brake. 2.
Page 291: Stalling On An Incline
What if I am driving across an incline that is not too steep, but I 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 292: Driving In Water
Driving in Mud, Sand, Snow or Ice When you drive in mud, snow or sand, your wheels will not get good traction. You cannot accelerate as quickly, turning is more difficult, and you will need longer braking distances. It is best to use a low gear when you are in mud — the deeper the mud, the lower the gear.
Page 293 If the water is not too deep, drive slowly through it. At faster speeds, water splashes on your ignition system and your vehicle can stall. Stalling can also occur if you get your tailpipe under water. And, as long as your tailpipe is under water, you will never be able to start your engine.
Page 294: 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 — by alcohol or drugs, with night vision problems, or by fatigue. 4-28 Here are some tips on night driving. •...
Page 295: Driving In Rain And On Wet Roads
You can be temporarily blinded by approaching headlamps. It can take a second or two, or even several seconds, for your eyes to re-adjust to the dark. When you are faced with severe glare, as from a driver who does not lower the high beams, or a vehicle with misaimed headlamps, slow down a little.
Page 296 The heavier the rain, the harder it is to see. Even if your windshield wiper blades are in good shape, a heavy rain can make it harder to see road signs and traffic signals, pavement markings, the edge of the road, and even people walking.
Page 297: Driving Through Flowing 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 are going fast enough. When your vehicle is hydroplaning, it has little or no contact with the road.
Page 298: City Driving
City Driving One of the biggest problems with city streets is the amount of traffic on them. You will want to watch out for what the other drivers are doing and pay attention to traffic signals. 4-32 Here are ways to increase your safety in city driving: •...
Page 299: 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 300: Before Leaving On A Long Trip
Just before you leave the lane, glance quickly over your shoulder to make sure there is not another vehicle in your blind spot. Once you are moving on the freeway, make certain you allow a reasonable following distance. Expect to move slightly slower at night.
Page 301: Highway Hypnosis

Page 302: Hill And Mountain Roads
Hill and Mountain Roads Driving on steep hills or mountains is different from driving in ﬂat or rolling terrain. 4-36 If you drive regularly in steep country, or if you are planning to visit there, here are some tips that can make your trips safer and more enjoyable.
Page 303 CAUTION: Coasting downhill in NEUTRAL (N) or with the ignition off is dangerous. Your brakes will have to do all the work of slowing down. They could get so hot that they would not work well. You would then have poor braking or even none going down a hill.
Page 304: 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. Also see Tires on page 5-50. 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, a red cloth, and reﬂective warning triangles.
Page 305 What is 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 is about freezing, 32°F (0°C), and freezing rain begins to fall.
Page 306: If You Are Caught In A Blizzard
Your anti-lock brake system (ABS) improves your vehicle’s stability when you make a hard stop on a slippery road. Even though you have ABS, you will want to begin stopping sooner than you would on dry pavement. See Anti-Lock Brake System (ABS) on page 4-6.
Page 307 You can run the engine to keep warm, but be careful. 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 cannot see it or smell it, so you might not know it is in your vehicle.
Page 308: If Your Vehicle Is Stuck In Sand, Mud, Ice Or Snow
Then, shut the engine off and close the window almost all the way to preserve the heat. Start the engine again and repeat this only when you feel really uncomfortable from the cold. But do it as little as possible. Preserve the fuel as long as you can. To help keep warm, you can get out of the vehicle and do some fairly vigorous exercises every half hour or so until help comes.
Page 309: Rocking Your Vehicle To Get It Out
Rocking Your Vehicle to Get It Out First, turn your steering wheel left and right. That will clear the area around your front wheels. If you have a four-wheel-drive vehicle, shift into 4HI. Then shift back and forth between REVERSE (R) and a forward gear, spinning the wheels as little as possible.
Page 310 Tire and Loading Information Label Label Example A vehicle speciﬁc Tire and Loading Information label is attached to the center pillar (B-pillar). With the driver’s door open, you will ﬁnd the label attached below the door lock post (striker). The tire and loading information label shows the number of occupant seating positions (A), and the maximum vehicle capacity weight (B) in kilograms and pounds.
Page 311 4. The resulting ﬁgure equals the available amount of cargo and luggage load capacity. For example, if the “XXX” amount equals 1400 lbs and there will be ﬁve 150 lb passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (1400 750 (5 x 150) = 650 lbs).
Page 312 Example 2 Item Description Vehicle Capacity Weight for Example 2 Subtract Occupant Weight 150 lbs (68 kg) Available Cargo Weight 4-46 Total Item 1,000 lbs (453 kg) 750 lbs (136 kg) 250 lbs (113 kg) Refer to your vehicle’s tire and loading information label for speciﬁc information about your vehicle’s capacity weight and seating positions.
Page 313 Certiﬁcation/Tire Label A vehicle speciﬁc Certiﬁcation/Tire label is found on the rear edge of the driver’s door. The label shows the size of your vehicle’s original tires and the inﬂation pressures needed to obtain the gross weight capacity of your vehicle. This is called Gross Vehicle Weight Rating (GVWR).
Page 314 CAUTION: Do not load your vehicle any heavier than the Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross Axle Weight Rating (GAWR). If you do, parts on your vehicle can break, and it can change the way your vehicle handles.
Page 315 Electronically Controlled Air Suspension System Your vehicle may be equipped with an electronically controlled air suspension system that automatically keeps your vehicle level as you load and unload. The system includes a compressor, two height sensors and two air springs supporting the rear axle. The system also has an internal clock to prevent overheating.
Page 316: Adding A Snow Plow Or Similar Equipment
Indicator Light The indicator light on the inﬂator switch in the rear passenger compartment also serves as an indicator for internal system error. If the indicator light is ﬂashing without the load leveling function or the inﬂator being active, turn off the ignition. The next day turn on the ignition and check the indicator light.

When to Add Engine Oil L6 Engine V8 Engine If the oil is below the L mark for the L6 engine or the cross-hatched area at the tip of the dipstick for the V8 engine, you will need to add at least one quart/liter of oil. 5-16 But you must use the right kind.
Page 349: What Kind Of Engine Oil To Use
What Kind of Engine Oil to Use Look for two things: • GM6094M Your vehicle’s engine requires oil meeting GM Standard GM6094M. You should look for and use only an oil that meets GM Standard GM6094M. • SAE 5W-30 As shown in the viscosity chart, SAE 5W-30 is best for your vehicle.
Page 350: Engine Oil Additives
If you are in an area of extreme cold, where the temperature falls below 20°F ( 29°C), it is recommended that you use either an SAE 5W-30 synthetic oil or an SAE 0W-30 oil. Both will provide easier cold starting and better protection for your engine at extremely low temperatures.
Page 351: Engine Air Cleaner/Filter
To reset the change engine oil light, do the following: 1. Turn the ignition key to RUN with the engine off. 2. Fully press and release the accelerator pedal slowly three times within ﬁve seconds. 3. Turn the key to LOCK. If the change engine oil light comes back on when you start your vehicle, the engine oil life system has not reset.
Page 352: How To Inspect The Engine Air Cleaner/Filter
When to Inspect the Engine Air Cleaner/Filter Inspect the air cleaner/ﬁlter at the Maintenance II intervals and replace at the ﬁrst oil change after each 50,000 mile (83 000 km) interval. See Scheduled Maintenance on page 6-4 for more information. If you are driving in dusty/dirty conditions, inspect the ﬁlter at each engine oil change.
Page 353: Automatic Transmission Fluid
Automatic Transmission Fluid When to Check and Change Automatic Transmission Fluid A good time to check your automatic transmission ﬂuid level is when the engine oil is changed. Change the ﬂuid and ﬁlter at the intervals listed in Additional Required Services on page 6-6, and be sure to use the transmission ﬂuid listed in Recommended Fluids and Lubricants on page 6-12.
Page 354 Checking the Fluid Level Prepare your vehicle as follows: • Park your vehicle on a level place. Keep the engine running. • With the parking brake applied, place the shift lever in PARK (P). • With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range.
Page 355: Engine Coolant
How to Add Automatic Transmission Fluid Refer to the Maintenance Schedule to determine what kind of transmission ﬂuid to use. See Recommended Fluids and Lubricants on page 6-12. Add ﬂuid only after checking the transmission ﬂuid while it is hot. A cold check is used only as a reference. If the ﬂuid level is low, add only enough of the proper ﬂuid to bring the level up to the HOT area for a hot check.
Page 356: What To Use
What to Use Use a mixture of one-half clean, drinkable water and ® one-half DEX-COOL coolant. If you use this coolant mixture, you do not need to add anything else. CAUTION: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will.
Page 357 Adding Coolant If you need more coolant, add the proper DEX-COOL coolant mixture at the coolant recovery tank. CAUTION: Turning the radiator pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly.
Page 358: Radiator Pressure Cap
Radiator Pressure Cap Notice: If the pressure cap is not tightly installed, coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured. See Engine Compartment Overview on page 5-12 for information on location. Engine Overheating You will ﬁnd a coolant temperature gage on your vehicle’s instrument panel.
Page 359: If No Steam Is Coming From Your Engine
If No Steam Is Coming From Your Engine If you get an engine overheat warning but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you: • Climb a long hill on a hot day.

Page 361 The coolant level should be at least up to the FULL COLD mark. If it is not, you may have a leak at the pressure cap or in the radiator hoses, heater hoses, radiator, water pump, or somewhere else in the cooling system. CAUTION: Heater and radiator hoses, and other engine parts, can be very hot.
Page 362 How to Add Coolant to the Coolant Recovery Tank If you have not found a problem yet, but the coolant level is not at the FULL COLD mark, add a 50/50 mixture of clean, drinkable water and DEX-COOL engine coolant at the coolant recovery tank. See Engine Coolant on page 5-23 for more information.
Page 363: How To Add Coolant To The Radiator
If the overheat warning continues, there is one more thing you can try. You can add the proper coolant mixture directly to the radiator, but be sure the cooling system is cool before you do it. CAUTION: Steam and scalding liquids from a hot cooling system can blow out and burn you badly.
Page 364 3. Fill the radiator with the proper DEX-COOL coolant mixture, up to the base of the ﬁller neck. See Engine Coolant on page 5-23 for more information about the proper coolant mixture. 5-32 ® 4. Then ﬁll the coolant recovery tank to the FULL COLD mark.
Page 365: Engine Fan Noise
6. Start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan. 7. By this time, the coolant level inside the radiator ﬁller neck may be lower. If the level is lower, add more of the proper DEX-COOL through the ﬁller neck until the level reaches the base of the ﬁller neck.
Page 366: Power Steering Fluid

Page 368: Checking Brake Fluid
So, it is not a good idea to top off your brake ﬂuid. Adding brake ﬂuid will not correct a leak. If you add ﬂuid when your linings are worn, then you will 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 369: Brake Wear
Always clean the brake ﬂuid reservoir cap and the area around the cap before removing it. This will help keep dirt from entering the reservoir. CAUTION: With the wrong kind of ﬂuid in your brake system, your brakes may not work well, or they may not even work at all.
Page 370: Battery
Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly tighten wheel nuts in the proper sequence to GM torque speciﬁcations. Brake linings should always be replaced as complete axle sets.
Page 371: Vehicle Storage
Vehicle Storage If you are not going to drive your vehicle for 25 days or more, remove the black, negative ( ) cable from the battery. This will help keep your battery from running down. CAUTION: Batteries have acid that can burn you and gas that can explode.
Page 372 2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles are not touching each other. If they are, it could cause a ground connection you do not want. You would not be able to start your vehicle, and the bad grounding could damage the electrical systems.
Page 373 CAUTION: Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running. 5. Check that the jumper cables do not have loose or missing insulation. If they do, you could get a shock.

Page 386: Tire Terminology And Deﬁnitions
Tire Terminology and Deﬁnitions Air Pressure: The amount of air inside the tire pressing outward on each square inch of the tire. Air pressure is expressed in pounds per square inch (psi) or kilopascal (kPa). Accessory Weight: This means the combined weight of optional accessories.
Page 387 Load Index: An assigned number ranging from 1 to 279 that corresponds to the load carrying capacity of a tire. Maximum Inﬂation Pressure: The maximum air pressure to which a cold tire may be inﬂated. The maximum air pressure is molded onto the sidewall. Maximum Load Rating: The load rating for a tire at the maximum permissible inﬂation pressure for that tire.
Page 388: Inﬂation - Tire Pressure
Treadwear Indicators: Narrow bands, sometimes called “wear bars,” that show across the tread of a tire when only 1/16 inch (1.6 mm) of tread remains. See When It Is Time for New Tires on page 5-59. UTQGS (Uniform Tire Quality Grading Standards): A tire information system that provides consumers with ratings for a tire’s traction, temperature, and treadwear.
Page 389: How To Check
A Tire and Loading Information label is attached to the vehicle’s center pillar (B-pillar), below the driver’s door latch. This label shows your vehicle’s original equipment tires and the correct inﬂation pressures for your tires when they are cold. The recommended cold tire inﬂation pressure, shown on the label, is the minimum amount of air pressure needed to support your vehicle’s maximum load carrying capacity.
Page 390 The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The ﬁrst rotation is the most important. See Scheduled Maintenance on page 6-4. When rotating your tires, always use the correct rotation pattern shown here. After the tires have been rotated, adjust the front and rear inﬂation pressures as shown on the Tire and Loading Information label.
Page 391: When It Is Time For New Tires
When It Is 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. Some commercial truck tires may not have treadwear indicators.
Page 392: Uniform Tire Quality Grading
If you replace your tires with those not having a TPC Spec number, make sure they are the same size, load range, speed rating and construction type (bias, bias-belted or radial) as your original tires. CAUTION: Mixing tires could cause you to lose control while driving.
Page 393: 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 (1.5) times as well on the government course as a tire graded 100.
Page 394: 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). See your dealer if any of these conditions exist.
Page 395: Tire Chains
Used Replacement Wheels CAUTION: Putting a used wheel on your vehicle is dangerous. You cannot know how it has been used or how far it has been driven. It could fail suddenly and cause a crash. If you have to replace a wheel, use a new GM original equipment wheel.
Page 396: Accessory Inﬂator
Accessory Inﬂator Your vehicle has an accessory inﬂator system. You can inﬂate things like basketballs and bicycle tires. You can also use it to bring your tire pressure up to the proper pressure. It is not designed to inﬂate large objects which will require more than ﬁve minutes to inﬂate, such as an air mattress.
