Page 2: How To Use This Manual
GENERAL MOTORS, GM, the GM Emblem, GMC, the GMC Truck Emblem, and the name SIERRA are registered trademarks of General Motors Corporation. This manual includes the latest information at the time it was printed. We reserve the right to make changes after that time without further notice.
Page 3 Safety Warnings and Symbols There are a number of safety cautions in this book. We use a box and the word CAUTION to tell about things that could hurt you if you were to ignore the warning. CAUTION: These mean there is something that could hurt you or other people.
Page 4 Vehicle Damage Warnings Also, in this manual you will ﬁnd these notices: Notice: These mean there is something that could damage your vehicle. A notice tells about something that can damage the vehicle. Many times, this damage would not be covered by your vehicle’s warranty, and it could be costly.

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 your vehicle has a power seat, you can adjust it with these controls located on the outboard sides of the seats. • Raise or lower the front of the seat cushion by raising or lowering the forward edge of the horizontal control.
Page 11: Power Lumbar
Power Lumbar Your vehicle’s seats may be equipped with power lumbar. You can increase or decrease lumbar support in an area of the lower seatback with this control, located on the outboard sides of the front seat(s). To increase support, press and hold the front of the control.
Page 12: Reclining Seatbacks
To heat only the seatback, press the vertical button with the heated seatback symbol. An indicator light on the seatback button will be lit to designate that only the seatback is being heated. Additional presses of the seatback button will cycle through the heat levels for the seatback only.
Page 13 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 not do their job when you are reclined like this. The shoulder belt can not do its job.
Page 14: Head Restraints
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. To raise the head restraint pull up on the head restraint. Your vehicle may have rear seat head restraints that can be adjusted up and down.
Page 15: Rear Seats
Rear Seats Rear Seat Operation (Extended Cab) Folding the Rear Seat The extended cab’s rear seat can be folded up to provide more cargo space. To fold the seat do the following: 1. Push down on the seat while pulling forward on the release strap located under the rear seat cushion.
Page 16 Rear Seat Operation (Crew Cab) The second row rear seat has a 60/40 split seat. Either side of the rear seat may be folded down to give you more cargo space. Make sure that nothing is under or in front of the seat and that the head restraints are completely lowered.
Page 17 Safety Belts Safety Belts: They Are for Everyone This part of the manual tells you how to use safety belts properly. It also tells you some things you should not do with safety belts. CAUTION: Do not let anyone ride where he or she can not wear a safety belt properly.
Page 18: Why Safety Belts Work
A few crashes are mild, and some crashes can be so serious that even buckled up, a person would not survive. But most crashes are in between. In many of them, people who buckle up can survive and sometimes walk away. Without belts they could have been badly hurt or killed.
Page 19 Put someone on it. Get it up to speed. Then stop the vehicle. The rider does not stop. 1-13...

Page 21 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. Questions and Answers About Safety Belts Will I be trapped in the vehicle after an accident...
Page 22 If I am a good driver, and I never drive far from home, why should I wear safety belts? You may be an excellent driver, but if you are in an accident — even one that is not your fault — you and your passengers can be hurt.
Page 23 3. 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. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly.
Page 24 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 25 What is wrong with this? The shoulder belt is too loose. It will not 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.
Page 26 What is wrong with this? The belt is buckled in the wrong place. 1-20 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 27 What is wrong with this? The belt is over an armrest. CAUTION: You can be seriously injured if your belt goes over an armrest like this. The belt would be much too high. In a crash, you can slide under the belt.
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 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 31 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 32: Lap Belt
Lap Belt When you sit in a center rear seat position of an extended cab or in the center front seat position of a crew cab, an extended cab, or a regular cab, you have a lap belt. Your lap safety belt has no retractor. To make the belt longer, tilt the latch plate and pull it along the belt.
Page 33 Rear Seat Passengers It is very important for rear seat passengers to buckle up! Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts. Rear passengers who are not safety belted can be thrown out of the vehicle in a crash.
Page 34 2. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. 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.
Page 35 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 36 To unlatch the belt, just push the button on the buckle. 1-30 Rear Safety Belt Comfort Guides for Children and Small Adults Rear seat comfort guides 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 37 2. Place the guide over the belt and insert the 3. Be sure that the belt is not twisted and it lies ﬂat. two edges of the belt into the slots of the guide. The guide must be on top of the belt. 1-31...
Page 38 4. Buckle, position and release the safety belt as described in Rear Seat Passengers on page 1-27. 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 of the guides.
Page 39: Child Restraints
Child Restraints 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 in a seat that has a lap-shoulder belt to get the additional restraint a shoulder belt can provide. What is the proper way to wear safety belts? If possible, an older child should wear a lap-shoulder belt and get the additional restraint a...
Page 40 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. 1-34 What if a child is wearing a lap-shoulder belt, but the child is so small that the shoulder belt...
Page 41: Infants And Young Children
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 42 CAUTION: People should never hold a baby in their arms while riding in a vehicle. A baby does not 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 (5.5 kg) baby will suddenly become a 240 lb (110 kg) force on a person’s arms.
Page 43 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. Neither the vehicle’s safety belt system nor its airbag system is designed for them.
Page 44 For most basic types of child restraints, there are many different models available. When purchasing a child restraint, be sure it is designed to be used in a motor vehicle. If it is, the restraint will have a label saying that it meets federal motor vehicle safety standards.
Page 45: 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 46 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. 1-40 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 47 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 48: 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 49: Top Strap
Do not use child restraints in the center front seat position. The restraints will not work properly. There is limited space in the rear seating area of an extended cab model. If you want to secure a child restraint in a rear seating position of an extended cab model, especially in the rear center position, be sure to study the instructions that came with your child restraint to see if there is enough room to secure...
Page 50 In Canada, the law requires that forward-facing child restraints have a top strap, and that the strap be anchored. In the United States, some child restraints also have a top strap. If your child restraint has a top strap, it should be anchored. Anchor the top strap to one of the following anchor points.
Page 51: Top Strap Anchor Location
Top Strap Anchor Location Regular Cab There is a top strap anchor for the right front passenger position located on the back panel of your vehicle, behind the right front passenger seat. In order to get to the anchor, you will have to remove the trim plug covering it.
Page 52 When using a child restraint with a top strap in either rear outboard position, raise the head restraint and route the top strap through the fabric loop on the seatback. Then, attach the top strap to the anchor point at the center rear seating position.
Page 53: Lower Anchorages And Top Tethers
Crew Cab Top strap anchors for the rear seating positions are located on the back panel of your vehicle, behind the rear seat. In order to get to the brackets, you will have to remove the trim plugs covering them. A child restraint with a top strap should only be used in the second row.
Page 54 A. Lower Anchorage B. Lower Anchorage C. Top Tether 1-48 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.
Page 55: Securing A Child Restraint Designed
To assist you in locating the lower anchors for this child restraint system, each seating position with the LATCH system has a visible metal anchor point in the seat where the seatback meets the seat cushion. CAUTION: If a LATCH-type child restraint is not attached to its anchorage points, the restraint will not be able to protect the child correctly.
Page 56: Securing A Child Restraint In A Rear
Securing a Child Restraint in a Rear Outside Seat Position Extended Cab and Crew Cab There is limited space in the rear seating of an extended cab model. If you want to secure a child restraint in a rear outside seating position, be sure to study the instructions that came with your child restraint to see if there is enough room to secure your seat properly.
Page 57 4. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 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.
Page 58: Securing A Child Restraint In A Center Rear Seat Position
Securing a Child Restraint in a Center Rear Seat Position If you have a extended cab or crew cab pickup, you can secure a child restraint in the center rear seat position. Crew Cab When you secure a child restraint in the center rear seat position of a crew cab, you will be using a lap-shoulder belt that works the same way as the safety belts in the rear outside seat positions.
Page 59: Securing A Child Restraint In The Center Front Seat Position
3. Run the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how. 4. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 5.
Page 60: Securing A Child Restraint In The Right Front Seat Position (Crew Cab)
Securing a Child Restraint in the Right Front Seat Position (Crew Cab) Your vehicle has a right front passenger airbag. Never put a rear-facing child restraint in the right front passenger’s seat. Here is why: CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inﬂates.

6. 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 63 CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the passenger’s airbag inﬂates. This is because the back of the rear-facing child restraint would be very close to the inﬂating airbag. Do not use a rear-facing child restraint in this vehicle unless the passenger’s airbag has been turned off.
Page 64 United States Never put a rear facing child restraint in the right front passenger’s seat unless the airbag is off. Here is why: 1-58 CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inﬂates.
Page 65 CAUTION: If the airbag readiness light in the instrument panel cluster ever comes on when you have turned off the airbag, it means that something may be wrong with the airbag system. The right front passenger’s airbag could inﬂate even though the switch is off. If this ever happens, have the vehicle serviced promptly.

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 68 Securing a Child Restraint in the Right Front Seat Position (Regular and Extended Cab) (With Passenger Sensing System) 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 1-42. In addition, your vehicle has the passenger sensing system.
Page 69 If you need to secure a forward-facing child restraint in the right front seat position, move the seat as far back as it will go before securing the forward-facing child restraint. See Power Seats on page 1-4 or Manual Seats on page 1-3. If your vehicle is an extended cab and your child restraint is equipped with the LATCH system, see Lower Anchorages and Top Tethers for Children (LATCH...

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 72: Airbag System
Airbag System Your vehicle has airbags — one airbag for the driver and another airbag for the right front passenger. Frontal airbags are designed to help reduce the risk of injury from the force of an inﬂating frontal airbag. But these airbags must inﬂate very quickly to do their job and comply with federal regulations.
Page 73 CAUTION: 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 before and during a crash.
Page 74: Where Are The Airbags
Where Are the Airbags? The driver’s airbag is in the middle of the steering wheel. 1-68 The right front passenger’s airbag is in the instrument panel on the passenger’s side.
Page 75: 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 76 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 4-20 for more tips on off-road driving. Single Stage vs.
Page 77: How Does An Airbag Restrain
Single Stage Airbags If your vehicle has frontal airbags with single stage deployment and your vehicle goes straight into a wall that does not move or deform, the threshold level is about 13 to 16 mph (20 to 25 km/h). (The threshold level can vary, however, with speciﬁc vehicle design, so that it can be somewhat above or below this range.) What Makes an Airbag Inﬂate?
Page 78: 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, or the instrument panel for the right front passenger’s bag –...
Page 79: Airbag Off Switch
• Let only qualiﬁed technicians work on your airbag system. Improper service can mean that an airbag system will not work properly. See your dealer for service. Notice: If you damage the covering for the driver’s or the right front passenger’s airbag, the bag may not work properly.
Page 80 Child age 1 to 12. A child age 1 to 12 must ride in the front seat because: • my vehicle has no rear seat; • although children ages 1 to 12 ride in the rear seat(s) whenever possible, children ages 1 to 12 sometimes must ride in the front because no space is available in the rear seat(s) of my vehicle;...
Page 81 United States To turn off the right front passenger’s airbag, insert your ignition key into the switch, push in, and move the switch to the off position. The airbag off light will come on to let you know that the right front passenger’s airbag is off.
Page 82: Passenger Sensing System
United States To turn the right front passenger’s airbag on again, insert your ignition key into the switch, push in, and move the switch to the on position. Passenger Sensing System If your rearview mirror has one of the indicators pictured in the following illustrations, your vehicle has a passenger sensing system.
Page 83 The passenger sensing system works with sensors that are part of the right front passenger’s seat and safety belt. The sensors are designed to detect the presence of a properly seated occupant and determine if the passenger’s frontal airbag should be enabled (may inﬂate) or not.
Page 84 • the system determines that a small child is present in a booster seat • a right front passenger takes his/her weight off of the seat for a period of time • the right front passenger seat is occupied by a smaller person, such as a child who has outgrown child restraints •...
Page 85 If a person of adult-size is sitting in the right front passenger’s seat, but the off indicator is lit, it could be because that person is not sitting properly in the seat. If this happens, turn the vehicle off and ask the person to place the seatback in the fully upright position, then sit upright in the seat, centered on the seat cushion, with the person’s legs comfortably extended.
Page 86: Servicing Your Airbag-Equipped Vehicle
Aftermarket equipment, such as seat covers, can affect how well the passenger sensing system operates. You may want to consider not using seat covers or other aftermarket equipment if your vehicle has the passenger sensing system. See Adding Equipment to Your Airbag-Equipped Vehicle on page 1-81 for more information about modiﬁcations that can affect how the system operates.
Page 87 Adding Equipment to Your Airbag-Equipped Vehicle Is there anything I might add to the front of the vehicle that could keep the airbags from working properly? Yes. If you add things that change your vehicle’s frame, bumper system, front end sheet metal or height, they may keep the airbag system from working properly.
Page 88: Restraint System Check
Restraint System Check Checking Your Restraint Systems Now and then, make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired.
Page 89 If you have had a crash, do you need new belts or LATCH system parts? After a very minor collision, nothing may be necessary. But if the belts were stretched, as they would be if worn during a more severe crash, then you need new parts. If the LATCH system was being used during a more severe crash, you may need new LATCH system parts.

(Lock): Press this button once to lock all of the doors. Pressing lock again within three seconds may cause the horn to chirp for lock conﬁrmation. You can choose different feedback options for each press of the lock button. See “Lock Feedback” and “Unlock Feedback”...
Page 97 To replace the battery in the keyless entry transmitter, do the following: 1. Insert a thin object, such as a coin, in the slot between the covers of the transmitter housing near the key ring hole. Remove the bottom by twisting the coin. 2.
Page 98: 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 296: 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 1-11. Defensive driving really means “be ready for anything.”...
Page 297 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 298 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 299: 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 300: Anti-Lock Brake System (Abs)
And, of course, actual stopping distances vary greatly with the surface of the road (whether it is pavement or gravel); the condition of the road (wet, dry, icy); tire tread; the condition of your brakes; the weight of the vehicle and the amount of brake force applied. Avoid needless heavy braking.
Page 301 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 302: 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.

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.

QUADRASTEER™ The QUADRASTEER™ System has a control and diagnostic module that monitors and records current system status and operational information. If your vehicle is equipped with the 4-Wheel Steer system, it has the ability to steer the vehicle with all four wheels.
Page 309 4: In this mode, all four wheels will help steer the vehicle. If you want to use 4, and your vehicle is not in this mode, press the button, until the 4 indicator, located to the right of the 4-Wheel Steer button, comes on and stays on.
Page 310 (4-Wheel Steer Tow Mode): When towing a trailer, the 4-wheel steer tow mode provides enhanced stability allowing the trailer to follow the path of the tow vehicle more closely, especially during lane changes. In this mode the system operates much like the 4 mode, but is enhanced for trailer towing.
Page 311: 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 312 • 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 313: Loss Of Control
Loss of Control Let us review what driving experts say about what happens when the three control systems — brakes, steering, and acceleration — do not have enough friction where the tires meet the road to do what the driver has asked.
Page 314: Off-Road Driving With Your Four-Wheel-Drive Vehicle
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 or is equipped with 20-inch tire/wheel assemblies, you should not drive off-road unless you are on a level, solid surface.
Page 315 The following steps must be performed on each of the push-pins to remove the air dam: 1. Insert a tool into the push-pin slot and pull downward until the push-pin snaps loose. 2. While continuing to pull downward on the push-pin, squeeze and turn the expandable end of the push-pin with...
Page 316 To reinstall the lower air dam, do the following: 1. Line up each push-pin with its intended retainer and push the washer portion of the push-pin toward the retainer until it locks into place. 2. Push the ﬂat end of the push-pin toward the retainer until it locks into place,...
Page 317: Environmental Concerns
CAUTION: • Cargo on the load ﬂoor piled higher than the seatbacks can be thrown forward during a sudden stop. You or your passengers could be injured. Keep cargo below the top of the seatbacks. • Unsecured cargo on the load ﬂoor can be tossed about when driving over rough terrain.
Page 318: Traveling To Remote Areas
Traveling to Remote Areas It makes sense to plan your trip, especially when going to a remote area. Know the terrain and plan your route. You are much less likely to get bad surprises. Get accurate maps of trails and terrain. Try to learn of any blocked or closed roads.
Page 319: Scanning The Terrain
Scanning the Terrain Off-road driving can take you over many different kinds of terrain. You need to be familiar with the terrain and its many different features. Here are some things to consider. Surface Conditions: Off-roading can take you over hard-packed dirt, gravel, rocks, grass, sand, mud, snow or ice.
Page 320 Driving on Off-Road Hills Off-road driving often takes you up, down or across a hill. Driving safely on hills requires good judgment and an understanding of what your vehicle can and cannot do. There are some hills that simply cannot be driven, no matter how well built the vehicle.
Page 321: Driving Uphill
• What is beyond the hill? Is there a cliff, an embankment, a drop-off, a fence? Get out and walk the hill if you do not know. It is the smart way to ﬁnd out. • Is the hill simply too rough? Steep hills often have ruts, gullies, troughs and exposed rocks because they are more susceptible to the effects of erosion.
Page 322 CAUTION: Driving to the top (crest) of a hill at full speed can cause an accident. There could be a drop-off, embankment, cliff, or even another vehicle. You could be seriously injured or killed. As you near the top of a hill, slow down and stay alert.
Page 323 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) (or pressing the clutch, if you have a manual transmission) to rev-up the engine and regain forward momentum.
Page 324: 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 325: 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 326: Stalling On An Incline
CAUTION: Driving across an incline that is too steep will make your vehicle roll over. You could be seriously injured or killed. If you have any doubt about the steepness of the incline, do not drive across it. Find another route instead. What if I am driving across an incline that is not too steep, but I hit some loose gravel and start to slide downhill.
Page 327: Driving In Water
CAUTION: Getting out on the downhill (low) side of a vehicle stopped across an incline is dangerous. If the vehicle rolls over, you could be crushed or killed. Always get out on the uphill (high) side of the vehicle and stay well clear of the rollover path.
Page 328 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 329: 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. •...
Page 330: 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 331 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 332: Driving Through Deep Standing Water
Driving Through Deep Standing Water Notice: If you drive too quickly through deep puddles or standing water, water can come in through your engine’s air intake and badly damage your engine. Never drive through water that is slightly lower than the underbody of your vehicle. If you cannot avoid deep puddles or standing water, drive through them very slowly.
Page 333: 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. Here are ways to increase your safety in city driving: •...
Page 334: 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. 4-40 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 335: Before Leaving On A Long Trip
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. Drive on to the next exit. The exit ramp can be curved, sometimes quite sharply. The exit speed is usually posted.
Page 336: 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 337 • Keep your vehicle in good shape. Check all ﬂuid levels and also the brakes, tires, cooling system, and transmission. These parts can work hard on mountain roads. • Know how to go down hills. The most important thing to know is this: let your engine do some of the slowing down.
Page 338: 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 5-72. 4-44 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 339 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;...
Page 340: If You Are Caught In A Blizzard
shaded areas where the sun cannot reach, such as around clumps of trees, behind buildings, or under bridges. Sometimes the surface of a curve or an overpass may remain icy when the surrounding roads are clear. If you see a patch of ice ahead of you, brake before you are on it.
Page 341 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 342: If You Are Stuck: In Sand, Mud, Ice Or Snow
If You Are Stuck: In Sand, Mud, Ice or Snow In order to free your vehicle when it is stuck, you will need to spin the wheels, but you do not want to spin your wheels too fast. The method known as rocking can help you get out when you are stuck, but you must use caution.
Page 343: Recovery Hooks
Recovery Hooks Your vehicle may be equipped with recovery hooks. The hooks are provided at the front of your vehicle. You may need to use them if you are stuck off-road and need to be pulled to some place where you can continue driving.
Page 344: Loading Your Vehicle
Loading Your Vehicle It is very important to know how much weight your vehicle can carry. This weight is called the vehicle capacity weight and includes the weight of all occupants, cargo and all nonfactory-installed options. Two labels on your vehicle show how much weight it was designed to carry, the Tire and Loading Information label and the Certiﬁcation/Tire label.
Page 345 There is also important loading information on the vehicle Certiﬁcation/Tire label. It tells you the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for the front and rear axles. See “Certiﬁcation/Tire Label” later in this section. Steps for Determining Correct Load Limit 1.
Page 346 Example 2 Item Description Vehicle Capacity Weight for Example 2 Subtract Occupant Weight 150 lbs (68 kg) Available Cargo Weight 4-52 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 347 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 348 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 349: Add-On Equipment
Two-Tiered Loading By positioning four 2” x 6” wooden planks across the width of the pickup box, you can create an upper load platform. The planks must be inserted in the pickup box depressions. The length of the planks must allow for at least a 3/4 inch (2 cm) bearing surface on each end of the plank.
Page 350: Adding A Snow Plow Or Similar Equipment
Adding a Snow Plow or Similar Equipment Before installing a snow plow on your vehicle, here are some things you will need to know: Notice: If your vehicle does not have the snow plow prep package, adding a plow can damage your vehicle, and the repairs would not be covered by warranty.
Page 351 Here are some guidelines for safely carrying a snow plow on your vehicle: • Make sure the weight on the front and rear axles does not exceed the axle rating for each. • For the front axle, if more cargo or passengers must be carried, appropriate counter ballast must be installed rear of the rear axle.
Page 352 In order to calculate the amount of weight any front accessory, such as a snow plow, is adding to the front axle, use the following formula: (W x (A + W.B.)) /W.B.= Weight the accessory is adding to the front axle. Where: W = Weight of added accessory A = Distance that the accessory is in front of the...
Page 353 CAUTION: On some vehicles equipped with certain front mounted equipment, such as a snow plow, it may be possible to load the front axle to the front GAWR but not have enough weight on the rear axle to have proper braking performance.
Page 354: Truck-Camper Loading Information
Truck-Camper Loading Information This label is inside your glove box. It will tell you if your vehicle can carry a slide-in camper, how much of a load your vehicle can carry, and how to correctly spread out your load. Also, it will help you match the right slide-in camper to your vehicle.
Page 355 Here is an example of proper truck and camper match: A. Camper Center of Gravity B. Recommended Center of Gravity Location Zone The camper’s center of gravity should fall within the center of gravity zone for your vehicle’s cargo load. You must weigh any accessories or other equipment that you add to your vehicle.
Page 356: Pickup Conversion To Chassis Cab
Pickup Conversion to Chassis Cab General Motors is aware that some vehicle owners may consider having the pickup box removed and a commercial or recreational body installed. Before you do so, ﬁrst contact GM Customer Assistance for information on such conversions speciﬁc to this vehicle. Owners should be aware that, as manufactured, there are differences between a chassis cab and a pickup with the box removed which may affect vehicle safety.
Page 357: Dinghy Towing
Dinghy Towing Two-Wheel-Drive Vehicles Notice: If you tow your vehicle with all four wheels on the ground, the drivetrain components could be damaged. The repairs would not be covered by your warranty. Do not tow your vehicle with all four wheels on the ground. Two-wheel-drive vehicles should not be towed with all four wheels on the ground.
Page 358: Dolly Towing
4. Securely attach the vehicle being towed to the tow vehicle. CAUTION: Shifting a four-wheel-drive vehicle’s transfer case into NEUTRAL can cause your vehicle to roll even if the transmission is in Park (P) for an automatic transmission, or if your vehicle is in gear, for a manual transmission.
Page 359 Four-Wheel-Drive Vehicles Use the following procedure to tow your vehicle: 1. Drive the vehicle up onto the tow dolly. 2. Shift an automatic transmission to PARK (P), or a manual transmission to FIRST (1). 3. Turn the engine off, but leave the ignition on. 4.
Page 360 Rear Towing (Rear Wheels Off the Ground) Two-Wheel-Drive Vehicles Use the following procedure to tow your vehicle from the rear: 1. Drive the vehicle onto the dolly. 2. Firmly set the parking brake. See Parking Brake on page 2-48. 3. Put an automatic transmission in PARK (P) or a manual transmission in FIRST (1).
Page 361: Trailer Recommendations
CAUTION: Shifting a four-wheel-drive vehicle’s transfer case into NEUTRAL can cause your vehicle to roll even if the transmission is in Park (P) for an automatic transmission, or if your vehicle is in gear, for a manual transmission. You or others could be injured.
Page 362: Towing A Trailer
Towing a Trailer Do not tow a trailer during break-in. See New Vehicle Break-In on page 2-21. CAUTION: If you do not 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 —...
Page 363 • Then, during the ﬁrst 500 miles (800 km) that you tow a trailer, don’t drive over 50 mph (80 km/h) and don’t make starts at full throttle. This helps your engine and other parts of your vehicle wear in at the heavier loads.
Page 364: Weight Of The Trailer
Operating the vehicle in Tow/Haul when lightly loaded or with no trailer at all will not cause damage. However, there is no beneﬁt to the selection of Tow/Haul when the vehicle is unloaded. Such a selection when unloaded may result in unpleasant engine and transmission driving characteristics and reduced fuel economy.

Page 378: Weight Of The Trailer Tongue
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 379 Do not exceed the maximum allowable tongue weight for your vehicle. Choose the shortest hitch extension that will position the hitch ball closest to the vehicle. This will help reduce the effect of trailer tongue weight on the rear axle. After you have loaded the trailer, weigh the trailer and then the tongue separately, to see if the weights are proper.
Page 380: Fifth Wheel And Gooseneck Trailering
If you will be pulling a trailer that, when loaded, will weigh more than 5,000 lbs (2 270 kg) be sure to use a properly mounted weight-distributing hitch and sway control of the proper size. This equipment is very important for proper vehicle loading and good handling when driving.
Page 381: Safety Chains
Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer.
Page 382: Driving With A Trailer
Driving with a Trailer CAUTION: If you have a rear-most window open and you pull a trailer with your vehicle, carbon monoxide (CO) could come into your vehicle. You cannot see or smell CO. It can cause unconsciousness or death. See Engine Exhaust on page 2-53.
Page 383: Turn Signals When Towing A Trailer
Passing You’ll need more passing distance up ahead when you’re towing a trailer. And, because you’re a good deal longer, you’ll need to go much farther beyond the passed vehicle before you can return to your lane. Backing Up Hold the bottom of the steering wheel with one hand. Then, to move the trailer to the left, just move that hand to the left.
Page 384: Parking On Hills
If you have a 5-speed manual transmission and you are towing a trailer, it’s better not to use FIFTH (5) gear. Just drive in FOURTH (4) gear (or, as you need to, a lower gear). If you have a 6-speed manual transmission and you are towing a trailer, it’s better not to use SIXTH (6) gear.
Page 385 5. If you have a four-wheel-drive vehicle, be sure the transfer case is in a drive gear and not in NEUTRAL. 6. Release the regular brakes. CAUTION: It can be dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake ﬁrmly set.
Page 386: Maintenance When Trailer Towing
Maintenance When Trailer Towing Your vehicle will need service more often when you’re pulling a trailer. See Scheduled Maintenance on page 6-4 for more information. Things that are especially important in trailer operation are automatic transmission ﬂuid (don’t overﬁll), engine oil, axle lubricant, belt, cooling system and brake system.
Page 387 Heavy-DutyTrailer Wiring Harness Package For vehicles equipped with heavy duty trailering, the harness is connected to the trailer plug mounted to the hitch platform. The eight-wire harness contains the following trailer circuits: • Yellow: Left Stop/Turn Signal • Dark Green: Right Stop/Turn Signal •...
Page 388 Camper/Fifth-Wheel Trailer Wiring Package The eight-wire camper harness is located under the front edge of the pickup box on the driver’s side of the vehicle, attached to the frame bracket. A connector will have to be added to the wiring harness which connects to the camper.
Page 389 Electric Brake Control Jumper CAUTION: Be sure to use only the correct trailer brake harness, the one intended for use on your vehicle. If you use some other trailer brake harness, even if it seems to ﬁt, your trailer brakes may not work at all. You could have a crash in which you or others could be injured.
Page 390 Four-Wire Harness Adapter This adapter is included with your vehicle as part of the heavy-duty trailer wiring package. Use this adapter to connect a standard four-way round pin connector to the seven-wire harness on your vehicle. 4-96 Connect the adapter with the tab pointing up (see arrow).
Page 391: Power Winches
Auxiliary Battery The auxiliary battery provision can be used to supply electrical power to additional equipment that you may choose to add, such as a slide-in camper. If your vehicle has this provision, this relay will be located on the passenger’s side of the vehicle, next to the auxiliary battery.
Page 392: Power Take-Off (Pto)
Power Take-Off (PTO) Before using a Power Take-Off (PTO), if equipped, refer to the manufacturer’s or installer’s instructions. To engage a PTO on a vehicle with a manual transmission do the following: 1. Hold the clutch pedal down. 2. Set the parking brake. 3.
Page 393 Preset Mode: PTO speed control mode is used for stationary applications. (PTO will remain engaged while mobile in the preset mode, however PTO set and resume speed controls will be inoperative.) This mode provides a default standby speed of 800 or 850 rpm (depending on the engine/transmission combination) and two default PTO control speeds which follow: 1.
Page 394 All engine speed values listed above are factory preset values. With the exception of the TCC lockup speed (1,100 rpm) and the “tap” increment (100 rpm), all of these values are programmable and can be adjusted by your dealer or body upﬁtter. If the PTO software settings do not match the settings shown here, then they may have already been altered in order to satisfy the requirements of the installed PTO system and body...

Page 400: Adding Equipment To The Outside Of Your Vehicle
Adding Equipment to the Outside of Your Vehicle Things you might add to the outside of your vehicle can affect the airﬂow around it. This may cause wind noise and affect windshield washer performance. Check with your dealer before adding equipment to the outside of your vehicle.
Page 401: Gasoline Speciﬁcations
Gasoline Speciﬁcations It is recommended that gasoline meet speciﬁcations which were developed by automobile manufacturers around the world and contained in the World-Wide Fuel Charter which is available from the Alliance of Automobile Manufacturers at www.autoalliance.org/fuel_charter.htm. Gasoline meeting these speciﬁcations could provide improved driveability and emission control system performance compared to other gasoline.
Page 402: Fuel E-85 (85% Ethanol)
Some gasolines that are not reformulated for low emissions may contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. General Motors does not recommend the use of such gasolines. Fuels containing MMT can reduce the life of spark plugs and the performance of the emission control system may be affected.
Page 403: Fuels In Foreign Countries
At a minimum, E-85 should meet ASTM Speciﬁcation D 5798. To ensure quick starts in the wintertime, the E-85 fuel must be formulated properly for your climate according to ASTM speciﬁcation D 5798. If you have trouble starting on E-85, it may be because your E-85 fuel is not properly formulated for your climate.

Page 414: Engine Oil (Gasoline Engine)
Engine Oil (Gasoline Engine) If your vehicle has a diesel engine, see “Engine Oil” in the Diesel Engine Supplement. If the CHECK OIL LEVEL light appears on the instrument cluster (except vehicles equipped with the 4.3L engine), it means you need to check your engine oil level right away.
Page 415 When to Add Engine Oil If the oil is at or below the cross-hatched area at the tip of the dipstick, then you will need to add at least one quart of oil. But you must use the right kind. This section explains what kind of oil to use.
Page 416 5-22 • SAE 5W-30 As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50. Oils meeting these requirements should also have the starburst symbol on the container.
Page 417: Engine Oil Additives
® GM Goodwrench oil meets all the requirements for your vehicle. 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 418: How To Reset The Engine Oil Life System
How to Reset the Engine Oil Life System The Engine Oil Life System calculates when to change your engine oil and ﬁlter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a CHANGE ENGINE OIL message being turned on, reset the system.

Page 443: Brakes
Brakes Brake Fluid Your brake master cylinder reservoir is ﬁlled with DOT-3 brake ﬂuid. See Engine Compartment Overview on page 5-14 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 444: Checking Brake Fluid
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 is not, 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 445: Brake Wear
Brake Wear Your vehicle has front disc brakes and may have rear drum brakes or rear disc brakes.

They can damage your vehicle because there’s not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension or other vehicle parts.
Page 485: If A Tire Goes Flat
If a Tire Goes Flat It’s unusual for a tire to “blowout” while you’re driving, especially if you maintain your tires properly. If air goes out of a tire, it’s much more likely to leak out slowly. But if you should ever have a “blowout,” here are a few tips about what to expect and what to do: If a front tire fails, the ﬂat tire will create a drag that pulls the vehicle toward that side.
Page 486: Changing A Flat Tire
Changing a Flat Tire If a tire goes ﬂat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning ﬂashers. CAUTION: Changing a tire can be dangerous. The vehicle can slip off the jack and roll over or fall on you or other people.

Page 510: Washing Your Vehicle
Washing Your Vehicle The paint ﬁnish on the vehicle provides beauty, depth of color, gloss retention, and durability. The best way to preserve the vehicle’s ﬁnish is to keep it clean by washing it often with lukewarm or cold water. Do not wash the vehicle in the direct rays of the sun.
Page 511: Windshield And Wiper Blades
Exterior painted surfaces are subject to aging, weather and chemical fallout that can take their toll over a period of years. You can help to keep the paint ﬁnish looking new by keeping your vehicle garaged or covered whenever possible. Protecting Exterior Bright Metal Parts Bright metal parts should be cleaned regularly to keep their luster.
Page 512: Tires
The surface of these wheels is similar to the painted surface of your vehicle. Do not use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid, or abrasive cleaning brushes on them because you could damage the surface. Do not use chrome polish on aluminum wheels.
