Section 1 Seats and Restraint Systems Here you’ll find information about the seats in your vehicle and how to use your safety belts properly. You can also learn about some things you should not do with air bags and safety belts. Seats and Seat Controls Safety Belts: They’re for Everyone Here Are Questions Many People Ask...
Page 15: 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 16 Manual Cushion Tilt (If Equipped) If your vehicle has this feature, you can raise or lower the front of the driver’s or passenger’s seat with this lever located at the inside edge of the seat. To raise or lower the front of the seat, move the lever up or down in a continuous motion until the cushion reaches the desired height.
Page 17 Power Seat(s) (If Equipped) Horizontal Control: If your vehicle has a power seat, you can adjust it with these controls located at the outboard edges of the seats. Raise or lower the front of the seat cushion by raising or lowering the forward edge of the button.
Page 18 Power Lumbar Control (If Equipped) To increase or decrease support, press and hold the front or rear of the control. Let go of the control when the lower seatback reaches the desired level of support. You can also reshape the side wing area of the lower seatback for more lateral support.
Page 19 Heated Front Seats (If Equipped) If your vehicle has heated front seats, the ignition must be in RUN for them to operate. The control for the driver’s side heated seat is located on the driver’s side door panel. The control for the passenger’s side heated seat is located on the passenger’s side door panel.
Page 20 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.
Page 21: 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. 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.
Page 22: Rear Seats
Rear Seats Utility: The rear seat may have a 60/40 split seat which may be folded down to give you more cargo space. The rear seatbacks may be equipped with rearward folding head restraints. When the seatback is being folded down, the head restraint will automatically fold rearward to allow a flat load floor for cargo or entry to the third row seat (if equipped).
Page 23 On Suburban/Yukon XL models with 60/40 split bench seats, before folding the rear seat on the driver’s side, insert the two buckles into the retainer in the seatback. That way, the buckles will be out of the way when the seat is folded and will be available for passengers to use when the seat is returned to the passenger position.
Page 24 Check to see that the buckles on the driver’s side seatback are accessible to the outboard and center occupant and are not under the seat cushions. If you have removed the head restraints to fold the rear bucket seat, be sure to reinstall them on the seatback after it has been returned to the normal seating position.
Page 25 If still more cargo space is desired, the third seat can also be folded and tumbled forward or removed if necessary by pulling up on the release lever labeled 2. The seat locks into place and does not need to be removed when carrying cargo.
Page 26 Push and pull on the seat, making sure the support rod is holding it firmly in place. Use the seat in this position only when necessary for additional cargo space. CAUTION: If the support rod isn’t properly engaged, the folded third row seat could come loose in a sudden stop or crash.
Page 27 To unlatch the seat from the back of the floor, pull up on the release lever labeled 2 at the rear of the seat and lift the rear of the seat up, off of the floor. Pull on the release lever located in the lower middle to unlatch the seat from the front of the floor and pull the seat out.
Page 28: Safety Belts: They're For Everyone
Suburban/Yukon XL: To put the seat back in, place the front of the seat on the load floor, facing the front of the vehicle. While holding the rear of the seat up, use the wheels on the front of the seat to roll it towards the seat hooks in the floor.
Page 29 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 30: 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’s just a seat on wheels. 1-17...
Page 31 Get it up to speed. Then stop the vehicle. The rider doesn’t stop. 1-18 The person keeps going until stopped by something. In a real vehicle, it could be the windshield ...
Page 32 or the instrument panel ... 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. 1-19...
Page 33: Here Are Questions Many People Ask About Safety Belts -- And The Answers
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 34: 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 35 4. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. If the belt isn’t long enough, see “Safety Belt Extender” at the end of this section. 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 36 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 37 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 38 What’s wrong with this? The shoulder belt is worn under the arm. It should be worn over the shoulder at all times. CAUTION: You can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would move too far forward, which would increase the chance of head and neck injury.
Page 39 What’s wrong with this? The belt is twisted across the body. 1-26 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 40: 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 41: 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 42 CAUTION: (Continued) Frontal air bags for the driver and right front passenger are designed to work only in moderate to severe crashes where the front of your vehicle hits something. They aren’t designed to inflate at all in rollover, rear, side or low crashes.
Page 43 CAUTION: Anyone who is up against, or very close to, any air bag when it inflates can be seriously injured or killed. Air bags plus lap shoulder belts offer the best protection for adults, but not for young children and infants. Neither the vehicle’s safety belt system nor its air bag system is designed for them.
Page 44 How the Air Bag Systems Work Where are the air bags? The driver’s frontal air bag is in the middle of the steering wheel. The right front passenger’s frontal air bag is in the instrument panel on the passenger’s side. The driver’s side impact air bag is in the side of the driver’s seatback closest to the door.
Page 45 The right front passenger’s side impact air bag is in the side of the passenger’s seatback closest to the door. 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.
Page 46 When should an air bag inflate? The driver’s and right front passenger’s frontal air bags are designed to inflate in moderate to severe frontal or near frontal crashes. But they are designed to inflate only if the impact speed is above the system’s designed “threshold level.”...
Page 47 How does an air bag restrain? In moderate to severe frontal or near frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. In moderate to severe side collisions, even belted occupants can contact the inside of the vehicle.
Page 48 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 a door.
Page 49 Servicing Your Air Bag-Equipped Vehicle Air bags affect how your vehicle should be serviced. There are parts of the air bag systems in several places around your vehicle. Your dealer and the service manual have information about servicing your vehicle and the air bag systems.
Page 50: Lap Belt
What if I add a snow plow? Will it keep the air bags from working properly? We’ve designed our air bag systems to work properly under a wide range of conditions, including snow plowing with vehicles equipped with the optional Snow Plow Prep Package (RPO VYU).
Page 51: Rear Seat Passengers
To make the belt shorter, pull its free end as shown until the belt is snug. Buckle, position and release it the same way as the lap part of a lap shoulder belt. If the belt isn’t 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 52: Rear Seat Outside Passenger Positions
Rear Seat Outside Passenger Positions Shoulder Belt The positions next to the windows have lap belts. Here’s how to wear one properly. 1. Pick up the latch plate and pull the belt across you. Don’t let it get twisted. 2. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure.
Page 53 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 54 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. To unlatch the belt, just push the button on the buckle. 1-41...
Page 55: 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 will provide added safety belt comfort for older children who have outgrown booster seats and for small adults. When installed on a shoulder belt, the comfort guide better positions the belt away from the neck and head.
Page 56 Third Row Seat 2. Place the guide over the belt and insert the two edges of the belt into the slots of the guide. 1-43...
Page 57 Second Row Seat 3. Be sure that the belt is not twisted and it lies flat. The guide must be on top of the belt. 1-44...
Page 58: Children
Third Row Seat 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 59 CAUTION: People should never hold a baby in their arms while riding in a vehicle. A baby doesn’t weigh much until a crash. During a crash a baby will become so heavy it is not possible to hold it. For example, in a crash at only 25 mph (40 km/h), a 12 lb.
Page 60 CAUTION: Children who are up against, or very close to, any air bag when it inflates can be seriously injured or killed. Air bags plus lap shoulder belts offer outstanding protection for adults and older children, but not for young children and infants. Neither the vehicle’s safety belt system nor its air bag system is designed for them.
Page 61 What are the different types of add child restraints? on child restraints, which are purchased by the vehicle’s owner, are available in four basic types. Selection of a particular restraint should take into consideration not only the child’s weight, height and age but also whether or not the restraint will be compatible with the motor vehicle in which it will be used.
Page 62: Restraint Systems For Children
CAUTION: The body structure of a young child is quite unlike that of an adult or older child, for whom the safety belts are designed. A young child’s hip bones are still so small that vehicle’s regular safety belt may not remain low on the hip bones, as it should.
Page 63 A rear facing infant seat (B) provides restraint with the seating surface against the back of the infant. The harness system holds the infant in place and, in a crash, acts to keep the infant positioned in the restraint. 1-50 A forward facing child seat (C E) provides restraint for...
Page 64 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 booster seat can also help a child to see out the window. How do child restraints work? A child restraint system is any device designed for use in a motor vehicle to restrain, seat, or position...
Page 65: 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 66: Top Strap
Top Strap Some child restraints have a top strap, or “top tether.” It can help restrain the child restraint during a collision. For it to work, a top strap must be properly anchored to the vehicle. If the child restraint does not have a top strap, one can be obtained, in kit form, for many child restraints.
Page 67 Suburban/Yukon XL models without rear seats: Top strap anchor loops are located at the bottom rear of the front seat cushion for the right front passenger’s position. Suburban/Yukon XL Models Without Rear Seats Anchor the top strap to this bracket. Once you have the top strap anchored, you’ll be ready to secure the child restraint itself.
Page 68 Suburban/Yukon XL Third Row Seat Utility models: A child restraint with a top strap should only be used in the second row. Don’t use a child restraint with a top strap in the right front passenger’s position or in the third row, because there’s no place to anchor the top strap.
Page 69: Securing A Child Restraint In A Rear Outside Seat Position
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 70: Securing A Child Restraint In A Center Rear Seat Position
4. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 5. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. If you’re using a forward facing child restraint, you may find it helpful to use your knee to push down on...
Page 71 1. Make the belt as long as possible by tilting the latch plate and pulling it along the belt. 2. Put the restraint on the seat. 3. Run the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how.
Page 72: Front Seat Position
6. Push and pull the child restraint in different directions to be sure it is secure. To remove the child restraint, just unbuckle the vehicle’s safety belt. It will be ready to work for an adult or larger child passenger. Securing a Child Restraint in the Center Front Seat Position Don’t use child restraints in this position.
Page 73 Your vehicle has a right front passenger air bag. Never put a rear facing child restraint in this seat. Here’s why: CAUTION: A child in a rear facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates.
Page 74 5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 6. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. You may find it helpful to use your knee to push down on the child restraint as you tighten the belt.
Page 75: Older Children
Older Children Older children who have outgrown booster seats should wear the vehicle’s safety belts. If you have the choice, a child should sit next to a window so the child can wear a lap get the additional restraint a shoulder belt can provide. 1-62 What is the proper way to wear safety belts? If possible, an older child should wear a...
Page 76 CAUTION: Never do this. Here two children are wearing the same belt. The belt can’t properly spread the impact forces. In a crash, the two children can be crushed together and seriously injured. A belt must be used by only one person at a time. What if a child is wearing a lap but the child is so small that the shoulder belt is very close to the child’s face or neck?
Page 77 1-64 CAUTION: Never do this. Here a child is sitting in a seat that has a shoulder belt, but the shoulder part is behind the child. If the child wears the belt in this way, in a crash the child might slide under the belt. The belt’s force would then be applied right on the child’s abdomen.
Page 78: Safety Belt Extender
Safety Belt Extender If the vehicle’s safety belt will fasten around you, you should use it. But if a safety belt isn’t long enough to fasten, your dealer will order you an extender. It’s free. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you.
Page 79 Section 2 Features and Controls Here you can learn about the many standard and optional features on your vehicle, and information on starting, shifting and braking. Also explained are the instrument panel and the warning systems that tell you if everything is working properly and what to do if you have a problem.
Page 80: Manual Windows
Windows CAUTION: Leaving children in a vehicle with the windows closed is dangerous. A child can be overcome by the extreme heat and can suffer permanent injuries or even death from heat stroke. Never leave a child alone in a vehicle, especially with the windows closed in warm or hot weather.
Page 81 Power Windows (If Equipped) If you have power windows, the controls are located on each of the side doors. The driver’s door has a switch for the passenger’s windows as well. Your power windows will work when the ignition has been turned to ACCESSORY or RUN or when Retained Accessory Power (RAP) is present.

Page 94: Ignition Positions
New Vehicle “Break In” NOTICE: Your vehicle doesn’t need an elaborate “break in.” But it will perform better in the long run if you follow these guidelines: Keep your speed at 55 mph (88 km/h) or less for the first 500 miles (805 km). Don’t drive at any one speed slow for the first 500 miles (805 km).
Page 95: Starting Your Engine
NOTICE: If your key seems stuck in LOCK and you can’t turn it, be sure you are using the correct key; if so, is it all the way in? Turn the key only with your hand. Using a tool to force it could break the key or the ignition switch.
Page 96 NOTICE: Holding your key in START for longer than 15 seconds at a time will cause your battery to be drained much sooner. And the excessive heat can damage your starter motor. Wait about 15 seconds between each try to help avoid draining your battery or damaging your starter.
Page 97: To Use The Engine Coolant Heater
Engine Coolant Heater (If Equipped) In very cold weather, 0 _ F 18 _ C) or colder, the engine coolant heater can help. You’ll get easier starting and better fuel economy during engine warm up. Usually, the coolant heater should be plugged in a minimum of four hours prior to starting your vehicle.
Page 98: Automatic Transmission Operation
Automatic Transmission Operation There are several different positions for your shift lever. Your vehicle is equipped with an automatic transmission and features an electronic shift position indicator within the instrument panel cluster. This display must be powered anytime the shift lever is capable of being moved out of PARK (P).
Page 99 CAUTION: (Continued) If you have four wheel drive, your vehicle will be free to roll even if your shift lever is in PARK (P) if your transfer case is in NEUTRAL. So, be sure the transfer case is in a drive gear, two wheel high (2H) or four high (4H) or four...
Page 100 NOTICE: Damage to your transmission caused by shifting out of PARK (P) or NEUTRAL (N) with the engine racing isn’t covered by your warranty. DRIVE (D): This position is for normal driving. If you need more power for passing, and you’re: Going less than about 35 mph (56 km/h), push your accelerator pedal about halfway down.
Page 101 NOTICE: If your rear wheels can’t rotate, don’t try to drive. This might happen if you were stuck in very deep sand or mud or were up against a solid object. You could damage your transmission. Also, if you stop when going uphill, don’t hold your vehicle there with only the accelerator pedal.
Page 102 Four Wheel Drive (If Equipped) If your vehicle has four wheel drive, you can send your engine’s driving power to all four wheels for extra traction. To get the most satisfaction out of four drive, you must be familiar with its operation. Read the part that follows before using four wheel drive.
Page 103 Automatic Transfer Case (If Equipped) The transfer case switches are located to the left of the instrument panel cluster. Use these switches to shift into and out of four wheel drive. You can choose among four driving settings: 2HI: This setting is used for driving in most street and highway situations.
Page 104 4HI: Use 4HI when you need extra traction, such as on snowy or icy roads or in most off road situations. This setting also engages your front axle to help drive your vehicle. This is the best setting to use when plowing snow. 4LO: This setting also engages your front axle and delivers extra torque.
Page 105 Shifting to 4LO To shift to 4LO, the ignition must be in RUN and the vehicle must be stopped or moving less than 3 mph (4.8 km/h) with the transmission in NEUTRAL (N). The preferred method for shifting into 4LO is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h).

Page 204 Section 4 Your Driving and the Road Here you’ll find information about driving on different kinds of roads and in varying weather conditions. We’ve also included many other useful tips on driving. Defensive Driving Drunken Driving Control of a Vehicle Braking Traction Assist System (Option) Steering...
Page 205: Defensive Driving
Defensive Driving The best advice anyone can give about driving is: Drive defensively. Please start with a very important safety device in your vehicle: Buckle up. See “Safety Belts” in the Index. Defensive driving really means “be ready for anything.” On city streets, rural roads or freeways, it means “always expect the unexpected.”...
Page 206: 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 207 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 208 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 209: 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 210: 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 211 Here’s how anti lock works. Let’s say the road is wet. You’re driving safely. Suddenly an animal jumps out in front of you. You slam on the brakes and continue braking. Here’s what happens with ABS. A computer senses that wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each front wheel and at both rear wheels.
Page 212: Traction Assist System (Option)
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 213 If your vehicle is in cruise control when the TAS begins to limit wheel spin, the cruise control will automatically disengage. When road conditions allow you to safely use it again, you may re engage the cruise control. See “Cruise Control” in the Index. When the TRACTION OFF light is on, the TAS is off and will not limit wheel...
Page 214: Steering
If you used the button to turn the system off, the TRACTION OFF light will come on and stay on. You can turn the system back on at any time by pressing the button again. The TRACTION OFF light should go off. If desired, you can change the TAS automatic engagement feature so that the system will not come on automatically when the engine is started.
Page 215: Steering Tips
Steering Tips Driving on Curves It’s important to take curves at a reasonable speed. A lot of the “driver lost control” accidents mentioned on the news happen on curves. Here’s why: Experienced driver or beginner, each of us is subject to the same laws of physics when driving on curves.
Page 216: Off - Road Recovery
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 217: Passing
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 218: 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 221 3. Pull the push lower air dam assembly away from the retainers until the lower air dam is free. When you’re back on roads, though, be sure to replace the air dam. NOTICE: Operating your vehicle for extended periods without the front bumper lower air dam installed can cause improper air flow to the engine and may allow things like fog lamps or tow hooks on the front of your vehicle to be damaged.
Page 222 Before You Go Off-Roading There are some things to do before you go out. For example, be sure to have all necessary maintenance and service work done. Check to make sure all underbody shields (if so equipped) are properly attached. Be sure you read all the information about your four vehicle in this manual.
Page 223: Environmental Concerns

GM recognizes these concerns and urges 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 recreational driving;...
Page 224: Scanning The Terrain
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 225: Approaching A Hill
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.
Page 226: Driving Uphill
On a large hill, the incline may get steeper as you near the top, but you may not see this because the crest of the hill is hidden by bushes, grass or shrubs. Here are some other things to consider as you approach a hill.
Page 227 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 228 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 won’t work. Your vehicle will roll backwards very quickly and you could go out of control.
Page 229: 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 230: 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 231: Stalling On An Incline
What if I’m driving across an incline that’s 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 232: Driving In Water
Driving in Mud, Sand, Snow or Ice When you drive in 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 in mud deeper the mud, the lower the gear.
Page 233 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 your tailpipe under water. And, as long as your tailpipe is under water, you’ll never be able to start your engine.
Page 234: 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. Here are some tips on night driving. Drive defensively.
Page 235: 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 readjust to the dark. When you are faced with severe glare (as from a driver who doesn’t lower the high beams, or a vehicle with misaimed headlamps), slow down a little.
Page 236 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 237: Driving Through Flowing Water
Hydroplaning doesn’t happen often. But it can if your tires do not have much tread or if the pressure in one or more is low. It can happen if a lot of water is standing on the road. If you can see reflections from trees, telephone poles or other vehicles, and raindrops “dimple”...
Page 238: City Driving
City Driving One of the biggest problems with city streets is the amount of traffic on them. You’ll want to watch out for what the other drivers are doing and pay attention to traffic signals. Here are ways to increase your safety in city driving: Know the best way to get to where you are going.
Page 239: 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. 4-36 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 240: Before Leaving On A Long Trip
Once you are moving on the freeway, make certain you allow a reasonable following distance. Expect to move slightly slower at night. When you want to leave the freeway, move to the proper lane well in advance. If you miss your exit, do not, under any circumstances, stop and back up.
Page 241: Highway Hypnosis
Highway Hypnosis Is there actually such a condition as “highway hypnosis”? Or is it just plain falling asleep at the wheel? Call it highway hypnosis, lack of awareness, or whatever. There is something about an easy stretch of road with the same scenery, along with the hum of the tires on the road, the drone of the engine, and the rush of the wind against the vehicle that can make you sleepy.
Page 242 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 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 243: Winter Driving
Winter Driving Here are some tips for winter driving: Have your vehicle in good shape for winter. You may want to put winter emergency supplies in your vehicle. 4-40 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 244 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 245 If You’re Caught in a Blizzard If you are stopped by heavy snow, you could be in a serious situation. You should probably stay with your vehicle unless you know for sure that you are near help and you can hike through the snow. Here are some things to do to summon help and keep yourself and your passengers safe: Turn on your hazard flashers.
Page 246 CAUTION: Snow can trap exhaust gases under your vehicle. This can cause deadly CO (carbon monoxide) gas to get inside. CO could overcome you and kill you. You can’t see it or smell it, so you might not know it is in your vehicle. Clear away snow from around the base of your vehicle, especially any that is blocking your exhaust pipe.
Page 247: Recreational Vehicle Towing
Recreational Vehicle Towing There may be times when you want to tow your vehicle behind another vehicle for use at your destination. Be sure to use the proper towing equipment designed for recreational vehicle towing. Follow the instructions for the towing equipment. When towing your vehicle, turn the ignition to OFF.
Page 248 Four-Wheel-Drive Vehicles CAUTION: Shifting the transfer case into NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P), for an automatic transmission. You or others could be injured. Make sure the parking brake is firmly set before you shift the transfer case into NEUTRAL.
Page 249: Loading Your Vehicle
Loading Your Vehicle The Certification/Tire label is found on the rear edge of the driver’s door or in the Incomplete Vehicle Document in the cab. The label shows the size of your original tires and the inflation pressures needed to obtain the gross weight capacity of your vehicle.
Page 250 The Certification/Tire label also tells you the maximum weights for the front and rear axles, called Gross Axle Weight Rating (GAWR). To find out the actual loads on your front and rear axles, you need to go to a weigh station and weigh your vehicle.
Page 251 Your warranty does not cover parts or components that fail because of overloading. The label will help you decide how much cargo and installed equipment your truck can carry. Using heavier suspension components to get added durability might not change your weight ratings. Ask your dealer to help you load your vehicle the right way.
Page 252: Trailer Recommendations
There’s also important loading information for off driving in this manual. See “Loading Your Vehicle for Road Driving” in the Index. Trailer Recommendations You must subtract your hitch loads from the CWR for your vehicle. Weigh your vehicle with the trailer attached, so that you won’t go over the GVWR or GAWR.
Page 253: Towing A Trailer
Towing a Trailer CAUTION: If you don’t use the correct equipment and drive properly, you can lose control when you pull a trailer. For example, if the trailer is too heavy, the brakes may not work well or even at all. You and your passengers could be seriously injured.
Page 254: If You Do Decide To Pull A Trailer
If You Do Decide To Pull A Trailer If you do, here are some important points: There are many different laws, including speed limit restrictions, having to do with trailering. Make sure your rig will be legal, not only where you live but also where you’ll be driving.

Weight of the Trailer Tongue The tongue load (A) of any trailer is an important weight to measure because it affects the total or gross weight of your vehicle. The Gross Vehicle Weight (GVW) includes the curb weight of the vehicle, any cargo you may carry in it, and the people who will be riding in the vehicle.
Page 259: Safety Chains
Hitches It’s important to have the correct hitch equipment. Crosswinds, large trucks going by and rough roads are a few reasons why you’ll need the right hitch. Here are some rules to follow: If you use a step bumper hitch, your bumper could be damaged in sharp turns.
Page 260: Driving With A Trailer
Trailer Brakes If your trailer weighs more than 2,000 lbs. (900 kg) loaded, then it needs its own brakes be adequate. Be sure to read and follow the instructions for the trailer brakes so you’ll be able to install, adjust and maintain them properly.
Page 261: Following Distance
Towing a trailer requires a certain amount of experience. Before setting out for the open road, you’ll want to get to know your rig. Acquaint yourself with the feel of handling and braking with the added weight of the trailer. And always keep in mind that the vehicle you are driving is now a good deal longer and not nearly as responsive as your vehicle is by itself.
Page 262: Making Turns
Making Turns NOTICE: Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. Your vehicle could be damaged. Avoid making very sharp turns while trailering. When you’re turning with a trailer, make wider turns than normal.
Page 263: Parking On Hills
Parking on Hills CAUTION: You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could start to move.

How to Check Because this operation can be a little difficult, you may choose to have this done at the dealership service department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick.
Page 326 A cold fluid check can be made after the vehicle has been sitting for eight hours or more with the engine off, but this is used only as a reference. Let the engine run at idle for five minutes if outside temperatures are 50 C) or more.
Page 327: How To Add Fluid
2. Push it back in all the way, wait three seconds and then pull it back out again. 3. Check both sides of the dipstick, and read the lower level. The fluid level must be in the COLD area, below the cross hatched area, for a cold check or in the HOT area or cross hatched area for a hot check.
Page 328: Rear Axle
Rear Axle When to Check Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant. Additional rear axle scheduled maintenance is required when trailer towing. See “Scheduled Maintenance Services” in the Index. How to Check Lubricant 1500 Series shown, 2500 and 3500 Series similar The proper level for the 1500 Series is from 5/8 inch to 1 5/8 inch (15 mm to 40 mm) below the filler plug.
Page 329: Front Axle
How to Check Lubricant Automatic Transfer Case If the level is below the bottom of the filler plug hole, you’ll need to add some lubricant. Add enough lubricant to raise the level to the bottom of the filler plug hole. Use care not to overtighten plug.
Page 330: Engine Coolant
When the differential is cold, add enough lubricant to raise the level to 1/2 inch (12 mm) below the filler plug hole. When the differential is at operating temperature (warm), add enough lubricant to raise the level to the bottom of the filler plug hole.
Page 331 What to Use Use a mixture of one half clean, drinkable water and half DEX COOL coolant which won’t damage aluminum parts. If you use this coolant mixture, you don’t need to add anything else. CAUTION: Adding only plain water to your cooling system can be dangerous.
Page 332: Checking Coolant
Checking Coolant The coolant surge tank is located on the passenger’s side of the engine compartment. See “Engine Compartment Overview” in the Index for more information. CAUTION: Turning the surge tank pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly.
Page 333: Power Steering Fluid
Coolant Surge Tank Pressure Cap The coolant surge tank pressure cap must be fully installed on the coolant surge tank. NOTICE: Your coolant surge tank pressure cap is a 15 psi (105 kPa) pressure type cap and must be tightly installed to prevent coolant loss and possible engine damage from overheating.
Page 334: How To Check Power Steering Fluid
8100 Engines When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem.
Page 335: Adding Washer Fluid
Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure to read the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing.
Page 336: Brake Fluid
Brakes Brake Fluid Your brake master cylinder reservoir is filled with DOT See “Engine Compartment Overview” in the Index for the location of the reservoir. There are only two reasons why the brake fluid level in the reservoir might go down. The first is that the brake fluid goes down to an acceptable level during normal brake lining wear.
Page 337 Checking Brake Fluid You can check the brake fluid without taking off the cap. Just look at the brake fluid reservoir. The fluid level should be above MIN. If it isn’t, have your brake system checked to see if there is a leak. After work is done on the brake hydraulic system, make sure the level is above the MIN but not over the MAX mark.
Page 338: Brake Wear
NOTICE: Using the wrong fluid can badly damage brake system parts. For example, just a few drops of mineral based oil, such as engine oil, in your brake system can damage brake system parts so badly that they’ll have to be replaced.
Page 339: Brake Adjustment
NOTICE: Continuing to drive with worn out brake pads could result in costly brake repair. Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes.
Page 340: Bulb Replacement
Battery Your new vehicle comes with a maintenance free ACDelco battery. When it’s time for a new battery, get one that has the replacement number shown on the original battery’s label. We recommend an ACDelco battery. See “Engine Compartment Overview” in the Index for battery location.

Page 346: Windshield Wiper Blade Replacement
Windshield Wiper Blade Replacement Windshield wiper blades should be inspected at least twice a year for wear and cracking. See “Wiper Blade Check” in the Index for more information. Replacement blades come in different types and are removed in different ways. For proper type and length, see “Normal Maintenance Replacement Parts”...
Page 347 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 348 Inflation -- Tire Pressure The Certification/Tire label, which is on the rear edge of the driver’s door, shows the correct inflation pressures for your tires when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km).
Page 349: Tire Inspection And Rotation
When to Check Check your tires once a month or more. Also, check the tire pressure of the spare tire. How to Check Use a good quality pocket type gage to check tire pressure. You can’t tell if your tires are properly inflated simply by looking at them.
Page 350 CAUTION: Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle.
Page 351: Buying New Tires
Buying New Tires To find out what kind and size of tires you need, look at the Certification/Tire label. The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) number on each tire’s sidewall. When you get new tires, get ones with that same TPC Spec number.
Page 352: Uniform Tire Quality Grading
Uniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A The following information relates to the system developed by the United States National Highway Traffic Safety Administration, which grades tires by treadwear, traction and temperature performance.
Page 353: Wheel Replacement
Temperature A, B, C The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure.
Page 354 Each new wheel should have the same load capacity, diameter, width, offset and be mounted the same way as the one it replaces. If you need to replace any of your wheels, wheel bolts or wheel nuts, replace them only with new GM original equipment parts.
Page 355: Tire Chains
Tire Chains NOTICE: If your vehicle has P265/75R16, LT265/75R16, P265/70R16 or P265/70R17 size tires, don’t use tire chains. They can damage your vehicle because there’s not enough clearance. Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination and road conditions.
Page 356: Appearance Care
Appearance Care Remember, cleaning products can be hazardous. Some are toxic. Others can burst into flame if you strike a match or get them on a hot part of the vehicle. Some are dangerous if you breathe their fumes in a closed space. When you use anything from a container to clean your vehicle, be sure to follow the manufacturer’s warnings and instructions.
Page 357: Special Fabric Cleaning Problems
Here are some cleaning tips: Always read the instructions on the cleaner label. Clean up stains as soon as you can Carefully scrape off any excess stain. Use a clean cloth or sponge, and change to a clean area often. A soft brush may be used if stains are stubborn. If a ring forms on fabric after spot cleaning, clean the entire area immediately or it will set.
Page 358: Cleaning Vinyl
Cleaning Vinyl Use warm water and a clean cloth. Rub with a clean, damp cloth to remove dirt. You may have to do it more than once. Things like tar, asphalt and shoe polish will stain if you don’t get them off quickly. Use a clean cloth and a vinyl/leather cleaner.
Page 359: Cleaning Glass Surfaces
Cleaning Glass Surfaces Glass should be cleaned often. GM Glass Cleaner or a liquid household glass cleaner will remove normal tobacco smoke and dust films on interior glass. See “Appearance Care and Materials” in the Index. Don’t use abrasive cleaners on glass, because they may cause scratches.
Page 360: Cleaning The Outside Of Your Vehicle
Cleaning the Outside of Your Vehicle The paint finish on your vehicle provides beauty, depth of color, gloss retention and durability. Washing Your Vehicle The best way to preserve your vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water.
Page 361 Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage your vehicle’s finish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non abrasive cleaners that are marked safe for painted surfaces to remove foreign matter.
Page 362: Cleaning Tires
Cleaning Tires To clean your tires, use a stiff brush with a tire cleaner. NOTICE: When applying a tire dressing always take care to wipe off any overspray or splash from all painted surfaces on the body or wheels of the vehicle. Petroleum based products may damage the paint finish and tires.
Page 363: Underbody Maintenance
Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, accelerated corrosion (rust) can occur on the underbody parts such as fuel lines, frame, floor pan and exhaust system even though they have corrosion protection.
