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
Power Seats If the vehicle has power seats, the controls used to operate them are located on the outboard side of the seats. To adjust the seat, do any of the following: • Move the seat forward or rearward by sliding the horizontal control forward or rearward.
Page 11: Power Lumbar
Power Lumbar Your vehicle may have this feature. The control is located on the outboard side of the seat cushion. To increase or decrease support, hold the control forward or rearward. Keep in mind that as your seating position changes, as it may during long trips, so should the position of your lumbar support.
Page 12: Memory Seat And Mirrors
To heat only the seatback, press the vertical button with the heated seatback symbol. An indicator light on the seatback button will come on 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 To store the memory settings, do the following: 1. If you have an automatic transmission, place the vehicle in PARK (P). If you have a manual transmission, set the parking brake. 2. Adjust the driver’s seat, including the seatback recliner and lumbar, and both outside mirrors to your preference.
Page 14 Easy Exit Seat The controls for this memory function are located on the driver’s door. (Easy Exit Seat): This button is used to program and recall the desired driver’s seat position when exiting or entering the vehicle. The seat position can be saved for up to two drivers. To store the seat exit position, do the following: 1.
Page 15: Reclining Seatbacks
Reclining Seatbacks Manual Reclining Seatbacks 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 16 To return the seatback to an upright position, do the following: 1. Lift the lever fully without applying pressure to the seatback and the seatback will return to the upright position. 2. Push and pull on the seatback to make sure it is locked.
Page 17 CAUTION: Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts cannot do their job when you are reclined like this. The shoulder belt cannot do its job because it will not be against your body.
Page 18: Head Restraints
Head Restraints Adjust the head restraint so that the top of the restraint is at the same height as the occupant’s head. This position reduces the chance of a neck injury in a crash. Pull the head restraint up to raise it. Push the head restraint down to lower it.
Page 19: Rear Seats
Rear Seats Rear Seat Operation (Extended Cab) Folding the Rear Seat The rear seat in the extended cab can be folded up to provide more cargo space. To fold the seat up, do the following: Notice: Folding a rear seat with the safety belts still fastened may cause damage to the seat or the safety belts.
Page 20: Rear Seat Operation (Crew Cab)
Rear Seat Operation (Crew Cab) The second row seat is a 60/40 split seat. Either side of the rear seat may be ﬂipped and folded for added cargo space. Make sure that nothing is under or in front of the seat and that the head restraints are completely lowered.
Page 21 To return the seat to the normal seating position, do the following: 1. Lift the seatback up and push it rearward all the way. CAUTION: If the seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there.
Page 22: Safety Belts
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 cannot wear a safety belt properly.
Page 23 Your vehicle has a light that comes on as a reminder to buckle up. See Safety Belt Reminder Light on page 247. In most states and in all Canadian provinces, the law says to wear safety belts. Here is why: They work.

Page 26: Questions And Answers About Safety Belts
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...
Page 27: How To Wear Safety Belts Properly
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. Being a good driver does not protect you from things beyond your control, such as bad drivers.
Page 28 3. Pick up the latch plate and pull the belt across you. Do not let it get twisted. The lap-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 29 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 30 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 31 What is wrong with this? The lap belt is too loose. It will not give nearly as much protection this way. CAUTION: You can be seriously hurt if your lap belt is too loose. In a crash, you could slide under the lap belt and apply force at your abdomen.
Page 32 What is wrong with this? The belt is buckled in the wrong place. CAUTION: You can be seriously injured if your belt is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen.
Page 33 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. The belt force would then be applied at the abdomen, not at the pelvic bones, and that could cause serious or fatal injuries.
Page 34 What is 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 35 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 36: Safety Belt Use During Pregnancy
To unlatch the belt, 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 37: Right Front Passenger Position
Right Front Passenger Position To learn how to wear the right front passenger’s safety belt properly, see Driver Position on page 27. The right front passenger’s safety belt works the same way as the driver’s safety belt — except for one thing. If you ever pull the shoulder portion of the belt out all the way, you will engage the child restraint locking feature which may turn off the passenger’s frontal airbag.
Page 38: 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 is not long enough, see Safety Belt Extender on page 43.
Page 39 Lap-Shoulder Belt All rear seat positions have lap-shoulder belts. Here is how to wear one properly. 1. Pick up the latch plate and pull the belt across you. Do not let it get twisted. The shoulder belt may lock if you pull the belt across you very quickly.
Page 40 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 41: Rear Safety Belt Comfort Guides
To unlatch the belt, push the button on the buckle. Rear Safety Belt Comfort Guides Rear shoulder belt comfort guides may provide added safety belt comfort for older children who have outgrown booster seats and for some adults. When installed on a shoulder belt, the comfort guide positions the belt away from the neck and head.
Page 42 3. Be sure that the belt is not twisted and it lies ﬂat. The elastic cord must be under the belt and the guide on top. CAUTION: A safety belt that is not properly worn may not provide the protection needed in a crash.
Page 43: Safety Belt Extender
4. Buckle, position, and release the safety belt as described in Rear Seat Passengers on page 38. Make sure that the shoulder belt crosses the shoulder. To remove and store the comfort guide, squeeze the belt edges together so that you can take them out of the guides.
Page 44: Child Restraints
Child Restraints Older Children Older children who have outgrown booster seats should wear the vehicle’s safety belts. What is the proper way to wear safety belts? An older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide.
Page 45 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.
Page 46 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 47: Infants And Young Children
Infants and Young Children Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle.
Page 48 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...
Page 49 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 50 What are the different types of add-on child restraints? Add-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 51: Child Restraint Systems
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 the vehicle’s regular safety belt may not remain low on the hip bones, as it should.
Page 52 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. 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.
Page 53 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. A booster seat can also help a child to see out the window.
Page 54 Securing an Add-on Child Restraint in the Vehicle CAUTION: A child can be seriously injured or killed in a crash if the child restraint is not properly secured in the vehicle. Make sure the child restraint is properly installed in the vehicle using the vehicle’s safety belt or LATCH system, following the instructions that came with that restraint,...
Page 55: Where To Put The Restraint
CAUTION: A child can be seriously injured or killed in a crash if the child is not properly secured in the child restraint. Make sure the child is properly secured, following the instructions that came with that restraint. Because there are different systems, it is important to refer to the instructions that come with the restraint.
Page 56 Never put a rear facing child restraint in the right front passenger seat unless the airbag is off. 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. This is because the back of the rear-facing child restraint would be very close to the inﬂating airbag.
Page 57 CAUTION: A child in a child restraint in the center front seat can be badly injured or killed by the right front passenger’s airbag if it inﬂates. Never secure a child restraint in the center front seat. It is always better to secure a child restraint in the rear seat.
Page 58: Lower Anchors And Tethers For Children (Latch)
Lower Anchors and Tethers for Children (LATCH) The LATCH system holds a child restraint during driving or in a crash. This system is designed to make installation of a child restraint easier. The LATCH system uses anchors in the vehicle and attachments on the child restraint that are made for use with the LATCH system Make sure that a LATCH-compatible child restraint...
Page 59 Top Tether Anchor A top tether (A, C) anchors the top of the child restraint to the vehicle. A top tether anchor is built into the vehicle. The top tether attachment (B) on the child restraint connects to the top tether anchor in the vehicle in order to reduce the forward movement and rotation of the child restraint during driving or in a crash.
Page 60 Lower Anchor and Top Tether Anchor Locations Seating positions with top tether anchors. Regular Cab Front Seat — Bucket (Top Tether Anchor): Regular Cab Front Do not install a child restraint in the center front seat position.

Page 62 Regular Cab For regular cab models with a bench seat, the top tether anchors are located under trim covers on the back panel behind the center and passenger seats. Do not install a child restraint in the center seat position. See Securing a Child Restraint in the Center Front Seat Position on page 74 for more information.
Page 63 Crew Cab For crew cab models, there are covered top tether anchors for each seating position located on the back panel of your vehicle, behind the rear seat. Remove the trim covers to access the anchors. Do not secure a child restraint in the front passenger’s position if your vehicle has rear seats, if a national or local law requires that the top tether be attached, or if the instructions that come...
Page 64 Securing a Child Restraint Designed for the LATCH System CAUTION: If a LATCH-type child restraint is not attached to anchors, the restraint will not be able to protect the child correctly. In a crash, the child could be seriously injured or killed.
Page 65 CAUTION: Children can be seriously injured or strangled if a shoulder belt is wrapped around their neck and the safety belt continues to tighten. Secure any unused safety belts behind the child restraint so children cannot reach them. Pull the shoulder belt all the way out of the retractor to set the lock, if your vehicle has one, after the child restraint has been...
Page 66 If the position you are using does not have a head restraint and you are using a single tether, route the tether over the seatback. If the position you are using does not have a head restraint and you are using a dual tether, route the tether over the seatback.

Page 73 5. To tighten the belt, push down on the child restraint, pull the shoulder portion of the belt to tighten the lap portion of the belt and feed the shoulder belt back into the retractor. If you are using a forward-facing child restraint, you may ﬁnd it helpful to use your knee to push down on the child restraint as you tighten the belt.
Page 74: Securing A Child Restraint In The Center Front Seat Position
Securing a Child Restraint in the Center Front Seat Position CAUTION: A child in a child restraint in the center front seat can be badly injured or killed by the right front passenger’s airbag if it inﬂates. Never secure a child restraint in the center front seat.
Page 75 A rear seat is a safer place to secure a forward-facing child restraint. If you need to secure a forward-facing child restraint in the right front seat position, see Where to Put the Restraint on page 55. If your child restraint has the LATCH system, see Lower Anchors and Tethers for Children (LATCH) on page 58.

Page 78: (Regular And Extended Cab)
Securing a Child Restraint in the Right Front Seat Position (Regular and Extended Cab) (With Airbag Off Switch) 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 55.
Page 79 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 80 Never put a rear facing child restraint in the right front passenger’s seat unless the airbag is off. 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. This is because the back of the rear-facing child restraint would be very close to the inﬂating airbag.

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.
Page 83 6. To tighten the belt, push down on the child restraint, pull the shoulder belt to tighten the lap belt portion 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 84 To remove the child restraint, if the top tether is attached to the top tether anchor, disconnect it. Unbuckle the vehicle’s safety belt and let it go back all the way. The safety belt will move freely again and be ready to work for an adult or larger child passenger.
Page 85: Securing A Child Restraint In The Right Front Seat Position (Regular And Extended Cab) (With Passenger Sensing System)
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 55.
Page 86 Your vehicle may have a label on your sun visor that says, “Never put a rear-facing child seat in the front.” This is because the risk to the rear-facing child is so great, if the airbag deploys. CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inﬂates.

Refer to the instructions that came with the child restraint and to Lower Anchors and Tethers for Children (LATCH) on page 58.
Page 91: Airbag System
Airbag System Your vehicle has an airbag for the driver and an 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 92 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 93: Where Are The Airbags
There is an airbag readiness light on the instrument panel cluster, which shows the airbag symbol. The system checks the airbag electrical system for malfunctions. The light tells you if there is an electrical problem. See Airbag Readiness Light on page 247 for more information.
Page 94 The right front passenger’s airbag is in the instrument panel on the passenger’s side. 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.
Page 95: When Should An Airbag Inﬂate
When Should an Airbag Inﬂate? The driver’s and right front passenger’s frontal airbags are designed to inﬂate in moderate to severe frontal or near-frontal crashes. But they are designed to inﬂate only if the impact exceeds a predetermined deployment threshold. Deployment thresholds take into account a variety of desired deployment and non-deployment events and are used to predict how severe a crash is likely to be in...
Page 96 In any particular crash, no one can say whether an airbag should have inﬂated simply because of the damage to a vehicle or because of what the repair costs were. Inﬂation is determined by what the vehicle hits, the angle of the impact, and how quickly the vehicle slows down.
Page 97: What Makes An Airbag Inﬂate
Dual Stage Airbags If your vehicle has frontal airbags with dual stage deployment, the amount of restraint will adjust according to crash severity. Your vehicle has electronic frontal sensors which help the sensing system distinguish between a moderate and a more severe frontal impact.
Page 98: How Does An Airbag Restrain
How Does an Airbag Restrain? In moderate to severe frontal or near-frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. The airbag supplements the protection provided by safety belts. Airbags distribute the force of the impact more evenly over the occupant’s upper body, stopping the occupant more gradually.
Page 99 CAUTION: When an airbag inﬂates, there may be 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.
Page 100: Airbag Off Switch
Airbag Off Switch If your instrument panel has one of the switches pictured in the following illustrations, your vehicle has an airbag off switch that you can use to manually turn off the right front passenger’s airbag. United States This switch should only be turned to the off position if the person in the right front passenger’s position is a member of a passenger risk group identiﬁed by the national government as follows:...
Page 101 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 102 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. The light will stay on to remind you that the airbag is off.
Page 103: 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 104 The passenger sensing system will turn off the right front passenger’s frontal airbag under certain conditions. The driver’s airbag is not part of the passenger sensing system. The passenger sensing system works with sensors that are part of the right front passenger’s seat and safety belt.
Page 105 Never put a child in a rear-facing child restraint in the right front passenger seat unless the passenger airbag status indicator shows off and the airbag is off. 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.
Page 106 • 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. • Or, if there is a critical problem with the airbag system or the passenger sensing system.
Page 107 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...
Page 108: 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 109 for more information about modiﬁcations that can affect how the system operates.
Page 109: Adding Equipment To Your
CAUTION: For up to 10 seconds after the ignition key is turned off and the battery is disconnected, an airbag can still inﬂate during improper service. You can be injured if you are close to an airbag when it inﬂates. Avoid yellow connectors. They are probably part of the airbag system.
Page 110 What if I added a snow plow? Will it keep the airbags from working properly? We have designed our airbag systems to work properly under a wide range of conditions, including snow plowing with vehicles that have the optional Snow Plow Prep Package (RPO VYU).
Page 111: Restraint System Check
Restraint System Check Checking the 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.

Drunken Driving Death and injury associated with drinking and driving is a national tragedy. It is 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: •...
Page 358 According to the American Medical Association, a 180 lb (82 kg) person who drinks three 12 ounce (355 ml) bottles of beer in an hour will end up with a BAC of about 0.06 percent. The person would reach the same BAC by drinking three 4 ounce (120 ml) glasses of wine or three mixed drinks if each had 1-1/2 ounces (45 ml) of liquors like whiskey, gin, or vodka.
Page 359 But the ability to drive is affected well below a BAC of 0.10 percent. Research shows that the driving skills of many people are impaired at a BAC approaching 0.05 percent, and that the effects are worse at night. All drivers are impaired at BAC levels above 0.05 percent.
Page 360: 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 are driving on snow or ice, it is easy to ask more of those control systems than the tires and road can provide.
Page 361: Anti-Lock Brake System (Abs)
Avoid needless heavy braking. Some people drive in spurts — heavy acceleration followed by heavy braking — rather than keeping pace with traffic. This is a mistake. The brakes may not have time to cool between hard stops. The brakes will wear out much faster if you do a lot of heavy braking.
Page 362 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 363: Braking In Emergencies
Remember: ABS does not change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you will not have time to apply your brakes if that vehicle suddenly slows or stops.
Page 364 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 on page 217. When the traction off light is on, the TAS is off and will not limit...

Page 368 Steering in Emergencies There are times when steering can be more effective than braking. For example, you come over a hill and ﬁnd a truck stopped in your lane, or a car suddenly pulls out from nowhere, or a child darts out from between parked cars and stops right in front of you.
Page 369: 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 370 • Watch for traffic signs, pavement markings, and lines. If you can see a sign up ahead that might indicate a turn or an intersection, delay your pass. A broken center line usually indicates it is all right to pass, providing the road ahead is clear.
Page 371: Loss Of Control
• Try not to pass more than one vehicle at a time on two-lane roads. Reconsider before passing the next vehicle. • Do not overtake a slowly moving vehicle too rapidly. Even though the brake lamps are not ﬂashing, it may be slowing down or starting to turn.
Page 372: Off-Road Driving
If your vehicle starts to slide, ease your foot off the accelerator pedal and quickly steer the way you want the vehicle to go. If you start steering quickly enough, your vehicle may straighten out. Always be ready for a second skid if it occurs.

Page 377 Environmental Concerns Off-road driving can provide wholesome and satisfying recreation. However, it also raises environmental concerns. We recognize these concerns and urge every off-roader to follow these basic rules for protecting the environment: • Always use established trails, roads, and areas that have been specially set aside for public off-road recreational driving;...
Page 378 Getting Familiar with Off-Road Driving It is a good idea to practice in an area that is safe and close to home before you go into the wilderness. Off-road driving does require some new and different driving skills. Here is what we mean.
Page 379 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 380 When you drive over bumps, rocks, or other obstacles, your wheels can leave the ground. If this happens, even with one or two wheels, you cannot control the vehicle as well or at all. Because you will be on an unpaved surface, it is especially important to avoid sudden acceleration, sudden turns, or sudden braking.
Page 381 Approaching a Hill When you approach a hill, you need to decide if it is one of those hills that is just too steep to climb, descend, or cross. Steepness can be hard to judge. On a very small hill, for example, there may be a smooth, constant incline with only a small change in elevation where you can easily see all the way to the top.
Page 382 Driving Uphill Once you decide you can safely drive up the hill, you need to take some special steps. • Use a low gear and get a ﬁrm grip on the steering wheel. • Get a smooth start up the hill and try to maintain your speed.
Page 383 What should I do if my vehicle stalls, or is about to stall, and I cannot make it up the hill? If this happens, there are some things you should do, and there are some things you must not do. First, here is what you should do: •...
Page 384 Suppose, after stalling, I try to back down the hill and decide I just cannot do it. What should I do? Set the parking brake, put the transmission in PARK (P), or the manual transmission in FIRST (1), and turn off the engine. Leave the vehicle and go get some help.
Page 385 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 386 Are there some things I should not do when driving down a hill? Yes! These are important because if you ignore them you could lose control and have a serious accident. • When driving downhill, avoid turns that take you across the incline of the hill. A hill that is not too steep to drive down may be too steep to drive across.
Page 387 Driving Across an Incline Sooner or later, an off-road trail will probably go across the incline of a hill. If this happens, you have to decide whether to try to drive across the incline. Here are some things to consider: •...
Page 388 What if I am driving across an incline that is not too steep, but I hit some loose gravel and start to slide downhill. What should I do? If you feel your vehicle starting to slide sideways, turn downhill. This should help straighten out the vehicle and prevent the side slipping.
Page 389 Driving in Mud, Sand, Snow, or Ice When you drive in mud, snow, or sand, your wheels will not get good traction. You cannot accelerate as quickly, turning is more difficult, and you will need longer braking distances. If your vehicle has four-wheel drive, see Four-Wheel Drive on page 153 for transfer case mode selection.
Page 390 Driving in Water Heavy rain can mean ﬂash ﬂooding, and ﬂood waters demand extreme caution. Find out how deep the water is before you drive through it. If it is deep enough to cover the wheel hubs, axles, or exhaust pipe, do not try it — you probably will not get through.
Page 391: Driving At Night
After Off-Road Driving Remove any brush or debris that has collected on the underbody, chassis, or under the hood. These accumulations can be a ﬁre hazard. After operation in mud or sand, have the brake linings cleaned and checked. These substances can cause glazing and uneven braking.
Page 392: 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 393 And, if your tires do not have much tread left, you will get even less traction. It is always wise to go slower and be cautious if rain starts to fall while you are driving. The surface may get wet suddenly when your reﬂexes are tuned for driving on dry pavement.
Page 394 Hydroplaning Hydroplaning is dangerous. So much water can build up under your tires that they can actually ride on the water. This can happen if the road is wet enough and you are going fast enough. When your vehicle is hydroplaning, it has little or no contact with the road.
Page 395 Driving Through Flowing Water CAUTION: Flowing or rushing water creates strong forces. If you try to drive through ﬂowing water, as you might at a low water crossing, your vehicle can be carried away. As little as six inches of ﬂowing water can carry away a smaller vehicle.
Page 396: 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 397: Freeway Driving
Freeway Driving Mile for mile, freeways — also called thruways, parkways, expressways, turnpikes, or superhighways — are the safest of all roads. But they have their own special rules. The most important advice on freeway driving is: Keep up with traffic and keep to the right. Drive at the same speed most of the other drivers are driving.
Page 398: Before Leaving On A Long Trip
Before changing lanes, check your mirrors. Then use your turn signal. Just before you leave the lane, glance quickly over your shoulder to make sure there is not another vehicle in your blind spot. Once you are moving on the freeway, make certain you allow a reasonable following distance.
Page 399: Highway Hypnosis

Page 400: Hill And Mountain Roads
Hill and Mountain Roads Driving on steep hills or mountains is different from driving in ﬂat or rolling terrain. If you drive regularly in steep country, or if you are planning to visit there, here are some tips that can make your trips safer and more enjoyable. See Off-Road Driving on page 372 for information about driving off-road.
Page 401 CAUTION: Coasting downhill in NEUTRAL (N) or with the ignition off is dangerous. Your brakes will have to do all the work of slowing down. They could get so hot that they would not work well. You would then have poor braking or even none going down a hill.
Page 402: 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 543. 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...
Page 403 What is the worst time for this? Wet ice. Very cold snow or ice can be slick and hard to drive on. But wet ice can be even more trouble because it may offer the least traction of all. You can get wet ice when it is about freezing, 32°F (0°C), and freezing rain begins to fall.
Page 404 The Anti-Lock Brake System (ABS) improves your vehicle’s stability when you make a hard stop on a slippery road. Even though you have ABS, you will want to begin stopping sooner than you would on dry pavement. See Anti-Lock Brake System (ABS) on page 361.
Page 405 You can run the engine to keep warm, but be careful. CAUTION: Snow can trap exhaust gases under your vehicle. This can cause deadly CO (carbon monoxide) gas to get inside. CO could overcome you and kill you. You cannot see it or smell it, so you might not know it is in your vehicle.
Page 406: If Your Vehicle Is Stuck In Sand, Mud, Ice, Or Snow
You will need a well-charged battery to restart the vehicle, and possibly for signaling later on with your headlamps. Let the heater run for a while. Then, shut the engine off and close the window almost all the way to preserve the heat. Start the engine again and repeat this only when you feel really uncomfortable from the cold.
Page 407: Rocking Your Vehicle To Get It Out
Notice: Spinning the wheels can destroy parts of your vehicle as well as the tires. If you spin the wheels too fast while shifting the transmission back and forth, you can destroy the transmission. For information about using tire chains on your vehicle, see Tire Chains on page 562.
Page 408: Recovery Hooks
Recovery Hooks CAUTION: These hooks, when used, are under a lot of force. Always pull the vehicle straight out. Never pull on the hooks at a sideways angle. The hooks could break off and you or others could be injured from the chain or cable snapping back.
Page 409: 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 410 The Tire and Loading Information label also shows the size of the original equipment tires (C) and the recommended cold tire inﬂation pressures (D). For more information on tires and inﬂation see Tires on page 543 and Inﬂation - Tire Pressure on page 551.

Page 412 Example 3 Item Description Vehicle Capacity Weight for Example 3 Subtract Occupant Weight 200 lbs (91 kg) Available Cargo Weight Refer to your vehicle’s tire and loading information label for speciﬁc information about your vehicle’s capacity weight and seating positions. The combined weight of the driver, passengers, and cargo should never exceed your vehicle’s capacity weight.
Page 413 To ﬁnd out the actual loads on your front and rear axles, you need to go to a weigh station and weigh your vehicle. Your dealer can help you with this. Be sure to spread out your load equally on both sides of the centerline.
Page 414 If you put things inside your vehicle — like suitcases, tools, packages, or anything else — they go as fast as the vehicle goes. If you have to stop or turn quickly, or if there is a crash, they will keep going. CAUTION: Things you put inside your vehicle can strike and injure people in a sudden stop...
Page 415 Two-Tiered Loading By positioning four 2 inches (5 cm) by 6 inches (15 cm) 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 416: 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 417 Say, for example, you have a 700 lb (318 kg) snow plow. The total weight of all occupants and cargo inside the cab should not exceed 300 lb (135 kg). This means that you may only be able to carry one passenger. But, even this may be too much if you have got other equipment already adding to the weight of your vehicle.
Page 418 What is front axle reserve capacity, and how do I calculate it? Front axle reserve capacity is the difference between your front Gross Axle Weight Rating (GAWR) and the front axle weight of your vehicle with full fuel and passengers. Basically, it is the amount of weight you can add to your front axle before reaching your front GAWR.
Page 419 For example, adding a 700 lb (318 kg) snow plow actually adds more than 700 lbs (318 kg) to the front axle. Using the formula, if the snow plow is 4 ft (122 cm) in front of the front axle and the wheel base is 10 ft (305 cm), then: W = 700 lb (318 kg) A = 4 ft (122 cm)
Page 420 What is total vehicle reserve capacity? This is the difference between your GVWR and the weight of your truck with full fuel and passengers. It is the amount of weight you can add to your vehicle before reaching your GVWR. Keep in mind that reserve capacity numbers are intended as a guide when selecting the amount of equipment or cargo your truck can carry.
Page 421: Truck-Camper Loading Information
Truck-Camper Loading Information A vehicle speciﬁc Truck-Camper Loading information label is attached to the inside of your vehicle’s glove box. This label 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 the load.
Page 422 Here is an example of proper truck and camper match: A. Camper Center of Gravity B. Recommended Center of Gravity Location Zone When the truck is used to carry a slide-in camper, the total cargo load of the truck consists of the manufacturer’s camper weight ﬁgure, the weight of installed additional camper equipment not included in the manufacturer’s camper weight...
Page 423: Towing
If your vehicle has gone over the weight ratings, move or take out some things until all the weight falls below the ratings. Secure loose items to prevent weight shifts that could affect the balance of your vehicle. When the truck-camper is loaded, drive to a scale and weigh the front and the rear wheels separately to determine axle loads.
Page 424: Recreational Vehicle Towing
Recreational Vehicle Towing Recreational vehicle towing means towing your vehicle behind another vehicle – such as behind a motorhome. The two most common types of recreational vehicle towing are known as dinghy towing, towing your vehicle will all four wheels on the ground, and dolly towing, towing your vehicle with two wheels on the ground and two wheels up on a device known as a “dolly”.
Page 425 Four-Wheel-Drive Vehicles Use the following procedure to tow your vehicle: 1. Shift an automatic transmission to PARK (P), or a manual transmission to FIRST (1). 2. Turn the engine off, but leave the ignition on. 3. Firmly set the parking brake. 4.
Page 426 Dolly Towing Front Towing (Front Wheels Off the Ground) Two-Wheel-Drive Vehicles Notice: If you tow a two-wheel-drive vehicle with the rear wheels on the ground, the transmission could be damaged. The repairs would not be covered by your warranty. Never tow your vehicle with the rear wheels on the ground.
Page 427 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 428 Four-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 169 3. Put an automatic transmission in PARK (P) or a manual transmission in FIRST (1).

Page 445 The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and trailer including any passengers, cargo, equipment and conversions. The GCWR for your vehicle should not be exceeded. You can ask your dealer for our trailering information or advice, or you can write us at the address listed in your Warranty and Owner Assistance Information Booklet.
Page 446 The trailer tongue weight (A) should be 10 percent to 15 percent of the total loaded trailer weight, up to a maximum of 600 lbs (272 kg) for the 1500 or 2500 series, and up to a maximum of 750 lbs (340 kg) for the 2500 HD or 3500 series with a weight carrying hitch.
Page 447 Consider the following example: A vehicle model base weight is 5,500 lbs (2 495 kg); 2,800 lbs (1 270 kg) at the front axle and 2,700 lbs (1 225 kg) at the rear axle. It has a GVWR of 7,200 lbs (3 266 kg), a RGAWR of 4,000 lbs (1 814 kg) and a GCWR (Gross Combination Weight Rating) of 14,000 lbs (6 350 kg).
Page 448 The effect of tongue weight is about 1.5 times the actual weight. Dividing the 900 lbs (408 kg) by 1.5 leaves you with being able to handle only 600 lbs (272 kg) of tongue weight. Since tongue weight is usually at least 10 percent of total loaded trailer weight, you can expect that the largest trailer your vehicle can properly handle is 6,000 lbs (2 721 kg).
Page 449 Weight-Distributing Hitches and Weight Carrying Hitches A: Body to Ground Distance B: Front of Vehicle When using a weight-distributing hitch, the hitch must be adjusted so the distance (A) remains the same both before and after coupling the trailer to the tow vehicle. If you use a step-bumper hitch, the bumper could be damaged in sharp turns.
Page 450 The hitch should be located in the pickup bed so that it’s centerline is over or slightly in front of the rear axle. Take care that it is not so far forward that it will contact the back of the cab in sharp turns. This is especially important for short box pickups.
Page 451 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 174.
Page 452 Before you start, check all trailer hitch parts and attachments, safety chains, electrical connector, lamps, tires and mirror adjustment. If the trailer has electric brakes, start your vehicle and trailer moving and then apply the trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection at the same time.
Page 453 Turn Signals When Towing a Trailer The arrows on your instrument panel will ﬂash whenever you signal a turn or lane change. Properly hooked up, the trailer lamps will also ﬂash, telling other drivers you’re about to turn, change lanes or stop. When towing a trailer, the arrows on your instrument panel will ﬂash for turns even if the bulbs on the trailer are burned out.
Page 454 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. People can be injured, and both your vehicle and the trailer can be damaged.
Page 455 CAUTION: (Continued) Always put the automatic transmission shift lever fully in PARK (P) with the parking brake ﬁrmly set. If you have a manual transmission, turn the engine off and ﬁrmly set the parking brake. If the transfer case on four-wheel-drive vehicles is in NEUTRAL, your vehicle will be free to roll, even if your automatic transmission shift lever is in PARK (P).
Page 456 Maintenance When Trailer Towing Your vehicle will need service more often when you’re pulling a trailer. See Scheduled Maintenance (Gasoline Engine) on page 617 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 457 Heavy-DutyTrailer Wiring Harness Package For vehicles equipped with heavy duty trailering, the harness is connected to the trailer 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 458 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 459 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 460: Trailer Recommendations
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 461: 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 462 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 463 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.

Page 471: Gasoline Speciﬁcations
If your vehicle has the 6.0L V8 engine (VIN Code N), use premium unleaded gasoline with a posted octane rating of 91 or higher. You may also use regular unleaded gasoline rated at 87 octane or higher, but your vehicle’s acceleration may be slightly reduced, and you may notice a slight audible knocking noise, commonly referred to as spark knock.
Page 472: Additives
Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent engine and fuel system deposits from forming, allowing your emission control system to work properly. In most cases, you should not have to add anything to your fuel.
Page 473: Fuel E85 (85% Ethanol)
Fuel E85 (85% Ethanol) The 8th digit of your Vehicle Identiﬁcation Number (VIN) shows the code letter or number that identiﬁes your engine. You will ﬁnd the VIN at the top left of the instrument panel. See Vehicle Identiﬁcation Number (VIN) on page 598. If your vehicle has the 5.3L V8 engine (VIN Code Z only), you may use either regular unleaded gasoline or ethanol fuel containing up to...
Page 474: Fuels In Foreign Countries
E85 has less energy per gallon than gasoline, so you will need to reﬁll your fuel tank more often when using E85 than when you are using gasoline. See Filling the Tank on page 474. Notice: Some additives are not compatible with E85 fuel and may harm your fuel system.
Page 475 The tethered fuel cap is located behind a hinged fuel door on the driver’s side of the vehicle. If the vehicle has E85 fuel capability, a yellow cap with the words E85 or gasoline can be seen. To remove the fuel cap, turn it slowly counterclockwise.
Page 476 When replacing the fuel cap, turn it clockwise until it clicks. It will require more effort to turn the fuel cap on the last turn as you tighten it. Make sure the cap is fully installed. The diagnostic system can determine if the fuel cap has been left off or improperly installed.
Page 477: Filling A Portable Fuel Container
Filling a Portable Fuel Container CAUTION: Never ﬁll a portable fuel container while it is in your vehicle. Static electricity discharge from the container can ignite the gasoline vapor. You can be badly burned and your vehicle damaged if this occurs.
Page 478: Checking Things Under The Hood
Checking Things Under the Hood CAUTION: An electric fan under the hood can start up and injure you even when the engine is not running. Keep hands, clothing, and tools away from any underhood electric fan. CAUTION: Things that burn can get on hot engine parts and start a ﬁre.

Page 486: Engine Oil (Gasoline Engine)
Engine Oil (Gasoline Engine) If your vehicle has a diesel engine, see “Engine ® Oil” in the DURAMAX Diesel Engine Supplement. If the CHECK OIL LEVEL light appears on the instrument cluster, except vehicles that have the 4.3L engine, it means you need to check the engine oil level right away.
Page 487 When to Add Engine Oil All Except 8.1L Engine 8.1L Engine If the oil is below the cross-hatched area at the tip of the dipstick, you will need to add at least one quart/liter of oil. But you must use the right kind.
Page 488 What Kind of Engine Oil to Use Look for two things: • GM6094M Your vehicle’s engine requires oil meeting GM Standard GM6094M. You should look for and use only an oil that meets GM Standard GM6094M. • SAE 5W-30 As shown in the viscosity chart, SAE 5W-30 is best for your vehicle.
Page 489: Engine Oil Life System
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 the engine at extremely low temperatures.
Page 490 How to Reset the Engine Oil Life System The Engine Oil Life System calculates when to change the engine oil and ﬁlter based on vehicle use. Any time the oil is changed, reset the system so it can calculate when the next oil change is required.

Page 498 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°F (10°C) or more.
Page 499 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 or cross-hatched area for a hot check. Be sure to keep the dipstick pointed down to get an accurate reading.
Page 500: Manual Transmission Fluid
Manual Transmission Fluid When to Check Manual Transmission Fluid A good time to have your manual transmission ﬂuid checked is when the engine oil is changed. See Additional Required Services (Gasoline Engine) on page 621 to ﬁnd out when to change your transmission ﬂuid.
Page 501: Hydraulic Clutch
How to Add Manual Transmission Fluid Here is how to add ﬂuid. Refer to the Maintenance Schedule to determine what kind of ﬂuid to use. See Recommended Fluids and Lubricants on page 629. 1. Remove the ﬁller plug. 2. Add ﬂuid at the ﬁller plug hole. Add only enough ﬂuid to bring the ﬂuid level up to the bottom of the ﬁller plug hole.
Page 502: Engine Coolant
How to Check and Add Fluid The proper ﬂuid should be added if the level does not reach the bottom of the diaphragm when it is in place in the reservoir. See the instructions on the reservoir cap. Engine Coolant The cooling system in your vehicle is ﬁlled with ®...
Page 503 What to Use Use a mixture of one-half clean, drinkable water ® and one-half DEX-COOL coolant which will not damage aluminum parts. If you use this coolant mixture, you do not need to add anything else. CAUTION: Adding only plain water to your cooling system can be dangerous.
Page 504 Checking Coolant The coolant surge tank is located in the engine compartment on the passenger’s side of the vehicle. See Engine Compartment Overview on page 480 for more information on location. 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 505: Coolant Surge Tank Pressure Cap
Adding Coolant If you need more coolant, add the proper ® DEX-COOL coolant mixture at the surge tank, but only when the engine is cool. See Cooling System on page 508. CAUTION: You can be burned if you spill coolant on hot engine parts.
Page 506 If Steam Is Coming From Your Engine CAUTION: Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Turn it off and get everyone away from the vehicle until it cools down.
Page 507 If No Steam Is Coming From Your Engine The ENGINE COOLANT HOT message, along with a low coolant condition, can indicate a serious problem. If you get an engine overheat warning, but see or hear no steam, the problem may not be too serious.
Page 508: Overheated Engine Protection
Overheated Engine Protection Operating Mode (V8 Engines Only) If an overheated engine condition exists and the REDUCED ENGINE POWER message is displayed, an overheat protection mode which alternates ﬁring groups of cylinders helps prevent engine damage. In this mode, you will notice a loss in power and engine performance.
Page 509 All Other Engines A. Coolant Surge Tank B. Coolant Surge Tank Pressure Cap C. Engine Cooling Fan CAUTION: An electric fan under the hood can start up and injure you even when the engine is not running. Keep hands, clothing, and tools away from any underhood electric fan.
Page 510 The coolant level should be at or above the FULL COLD mark. If it is not, you may have a leak at the pressure cap or in the radiator hoses, heater hoses, radiator, water pump, or somewhere else in the cooling system.
Page 511 How to Add Coolant to the Coolant Surge Tank for Gasoline Engines If your vehicle has a diesel engine, see “Cooling ® System” in the DURAMAX Diesel Supplement for the proper coolant ﬁll procedure. If you have not found a problem yet, check to see if coolant is visible in the surge tank.
Page 512 CAUTION: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you would not get the overheat warning.
Page 513 2. Then keep turning the pressure cap slowly, and remove it. 3. Fill the coolant surge tank with the proper mixture, to the FULL COLD mark. 4. With the coolant surge tank pressure cap off, start the engine and let it run until you can feel the upper radiator hose getting hot.
Page 514: Engine Fan Noise
Engine Fan Noise If your vehicle has a clutched engine cooling fan, when the clutch is engaged, the fan spins faster to provide more air to cool the engine. In most everyday driving conditions, the fan is spinning slower and the clutch is not fully engaged. This improves fuel economy and reduces fan noise.
Page 515: Power Steering Fluid
Power Steering Fluid See Engine Compartment Overview on page 480 for reservoir location. 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 516: Windshield 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 517: Brakes
Brakes Brake Fluid Your brake master cylinder reservoir is ﬁlled with DOT-3 brake ﬂuid. See Engine Compartment Overview on page 480 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 518 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.
Page 519 Brake Wear Your vehicle has front disc brakes and may have rear drum brakes or rear disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and go or be heard all the time your vehicle is moving, except when you are pushing on the brake pedal ﬁrmly.
Page 520: Battery
Replacing Brake System Parts The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Your vehicle was designed and tested with top-quality GM brake parts.
Page 521: Jump Starting
Jump Starting If your vehicle’s battery (or batteries) has run down, you may want to use another vehicle and some jumper cables to start your vehicle. Be sure to use the following steps to do it safely. CAUTION: Batteries can hurt you. They can be dangerous because: •...
Page 522 3. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles are not touching each other. If they are, it could cause a ground connection you do not want. You would not be able to start your vehicle, and the bad grounding could damage the electrical systems.
Page 523 5. Open the hoods and locate the positive (+) and negative ( ) terminal locations of the other vehicle. Your vehicle has a remote positive (+) jump starting terminal and a remote negative ( ) jump starting terminal. You should always use these remote terminals instead of the terminals on the battery.
Page 524 CAUTION: Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running. 6. Check that the jumper cables do not have loose or missing insulation. If they do, you could get a shock.
Page 525 8. Do not let the other end touch metal. Connect it to the positive (+) terminal of the good battery. Use a remote positive (+) terminal if the vehicle has one. 9. Now connect the black negative ( ) cable to the negative ( ) terminal of the good battery.
Page 526 Notice: If the jumper cables are connected or removed in the wrong order, electrical shorting may occur and damage the vehicle. The repairs would not be covered by your warranty. Always connect and remove the jumper cables in the correct order, making sure that the cables do not touch each other or other metal.
Page 527: Rear Axle
Rear Axle When to Check Lubricant It is not necessary to regularly check rear axle ﬂuid unless you suspect there is a leak or you hear an unusual noise. A ﬂuid loss could indicate a problem. Have it inspected and repaired. All axle assemblies are ﬁlled by volume of ﬂuid during production.
Page 528: Four-Wheel Drive

Replacement blades come in different types and are removed in different ways. For proper type and length, see Normal Maintenance Replacement Parts (Gasoline Engines) on page 632.
Page 543: Tires
Tires Your new vehicle comes with high-quality tires made by 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. For additional information refer to the tire manufacturer’s booklet included with your vehicle.
Page 544: Tire Sidewall Labeling
20-Inch Tires If your vehicle has the optional 20-inch P275/55R20 size tires, they are classiﬁed as touring tires and are designed for on road use. The low-proﬁle, wide tread design is not recommended for “off-road” driving or commercial uses such as snow plowing.
Page 545 (B) TPC Spec (Tire Performance Criteria Speciﬁcation): Original equipment tires designed to GM’s speciﬁc tire performance criteria have a TPC speciﬁcation code molded onto the sidewall. GM’s TPC speciﬁcations meet or exceed all federal safety guidelines. (C) DOT (Department of Transportation): The Department of Transportation (DOT) code indicates that the tire is in compliance with the U.S.
Page 546 Light Truck (LT-Metric) Tire (A) Tire Size: The tire size code is a combination of letters and numbers used to deﬁne a particular tire’s width, height, aspect ratio, construction type, and service description. See the “Tire Size” illustration later in this section for more detail. (B) TPC Spec (Tire Performance Criteria Speciﬁcation): Original equipment tires designed to GM’s speciﬁc tire performance criteria have...
Page 547 (F) Tire Ply Material: The type of cord and number of plies in the sidewall and under the tread. (G) Single Tire Maximum Load: Maximum load that can be carried and the maximum pressure needed to support that load when used as a single.
Page 548: Tire Terminology And Deﬁnitions
(C) Aspect Ratio: A two-digit number that indicates the tire height-to-width measurements. For example, if the tire size aspect ratio is 75, as shown in item C of the light truck (LT-Metric) tire illustration, it would mean that the tire’s sidewall is 75 percent as high as it is wide.
Page 549 Cold Tire Pressure: The amount of air pressure in a tire, measured in pounds per square inch (psi) or kilopascals (kPa) before a tire has built up heat from driving. See Inﬂation - Tire Pressure on page 551. Curb Weight: This means the weight of a motor vehicle with standard and optional equipment including the maximum capacity of fuel, oil, and coolant, but without passengers and cargo.
Page 550 Occupant Distribution: Designated seating positions. Outward Facing Sidewall: The side of an asymmetrical tire that has a particular side that faces outward when mounted on a vehicle. The side of the tire that contains a whitewall, bears white lettering, or bears manufacturer, brand, and/or model name molding that is higher or deeper than the same moldings on the other sidewall of the tire.
Page 551: Inﬂation - Tire Pressure
Vehicle Maximum Load on the Tire: Load on an individual tire due to curb weight, accessory weight, occupant weight, and cargo weight. Vehicle Placard: A label permanently attached to a vehicle showing the vehicle’s capacity weight and the original equipment tire size and recommended inﬂation pressure.
Page 552: Dual Tire Operation
How to Check Use a good quality pocket-type gage to check tire pressure. You cannot tell if your tires are properly inﬂated simply by looking at them. Radial tires may look properly inﬂated even when they’re underinﬂated. Check the tire’s inﬂation pressure when the tires are cold.
Page 553: Tire Inspection And Rotation
Tire Inspection and Rotation Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See When It Is Time for New Tires on page 555 and Wheel Replacement on page 560 for more information.
Page 554 If your vehicle has dual rear wheels and the tread design for your front tires is the same as your rear tires, always use one of the correct rotation patterns shown here when rotating your tires. If your vehicle has dual rear wheels and the tread design for the front tires is different from the...
Page 555: When It Is Time For New Tires
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 556: Buying New Tires
You need a new tire if any of the following statements are true: • You can see the indicators at three or more places around the tire. • You can see cord or fabric showing through the tire’s rubber. • The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric.
Page 557 CAUTION: Mixing tires could cause you to lose control while driving. If you mix tires of different sizes, brands, or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes, brands or types may also cause damage to your vehicle.
Page 558: Different Size Tires And Wheels
Different Size Tires and Wheels If you add wheels or tires that are a different size than your original equipment wheels and tires, this may affect the way your vehicle performs, including its braking, ride and handling characteristics, stability, and resistance to rollover.
Page 559: 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 (NHTSA), which grades tires by treadwear, traction, and temperature performance.
Page 560: Wheel Alignment And Tire Balance
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 561 Each new wheel should have the same load-carrying 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 562: Tire Chains
Used Replacement Wheels CAUTION: Putting a used wheel on your vehicle is dangerous. You cannot know how it has been used or how far it has been driven. It could fail suddenly and cause a crash. If you have to replace a wheel, use a new GM original equipment wheel.
Page 563: If A Tire Goes Flat
CAUTION: (Continued) Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination and road conditions. Follow that manufacturer’s instructions. To help avoid damage to your vehicle, drive slowly, readjust or remove the device if it is contacting your vehicle, and do not spin your vehicle’s wheels.
Page 564: Changing A Flat Tire
A rear blowout, particularly on a curve, acts much like a skid and may require the same correction you would use in a skid. In any rear blowout remove your foot from the accelerator pedal. Get the vehicle under control by steering the way you want the vehicle to go.

GMC and General Motors of Canada Limited reserve the right to limit services or reimbursement to an owner or driver when, in their sole discretion, the claims become excessive in frequency or type of occurrence. Roadside Assistance is not part of or included in the coverage provided by the New Vehicle Limited Warranty.
Page 648 Scheduling Service Appointments When your vehicle requires warranty service, you should contact your dealer and request an appointment. By scheduling a service appointment and advising your service consultant of your transportation needs, your dealer can help minimize your inconvenience. If your vehicle cannot be scheduled into the service department immediately, keep driving it until it can be scheduled for service, unless, of course, the problem is safety-related.
Page 649 In addition, for U.S. customers, should you arrange transportation through a friend or relative, limited reimbursement for reasonable fuel expenses may be available. Claim amounts should reﬂect actual costs and be supported by original receipts. Courtesy Rental Vehicle Your dealer may arrange to provide you with a courtesy rental vehicle or reimburse you for a rental vehicle that you obtain if your vehicle is kept for an overnight warranty repair.
