3. To program your keyless entry transmitter, press the UNLOCK button within five seconds of programming the memory button. You will hear a chime to confirm programming of the transmitter. When your vehicle is in PARK (P), push and release the numbered memory button you just stored.
Page 17 Reclining Front Seatback The vertical power seat control described earlier allows the seatback to recline. But don’t have a seatback reclined if your vehicle is moving. CAUTION: Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can’t do their job when you’re reclined like this.
Page 18: Head Restraints
Head Restraints Slide the head restraint up or down so that the top of the restraint is closest to the top of your ears. This position reduces the chance of a neck injury in a crash. The rear seat head restraints in your vehicle are adjustable.
Page 19: Safety Belts: They're For Everyone
To return the head restraints to the upright position, reach behind the seats and pull the head restraint up until it locks into position. Push and pull on the head restraints to check that they have locked in the upright position. If they haven’t, have them fixed immediately.
Page 20 CAUTION: It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, people riding in these areas are more likely to be seriously injured or killed. Do not allow people to ride in any area of your vehicle that is not equipped with seats and safety belts.
Page 21: Why Safety Belts Work
Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. Put someone on it. Take the simplest vehicle. Suppose it’s just a seat on wheels.
Page 22 Get it up to speed. Then stop the vehicle. The rider doesn’t stop. 1-10 The person keeps going until stopped by something. In a real vehicle, it could be the windshield ...
Page 23 or the instrument panel ... or the safety belts! With safety belts, you slow down as the vehicle does. You get more time to stop. You stop over more distance, and your strongest bones take the forces. That’s why safety belts make such good sense. 1-11...
Page 24: Here Are Questions Many People Ask About
Here Are Questions Many People Ask About Safety Belts and the Answers Won’t I be trapped in the vehicle after an accident if I’m wearing a safety belt? You could be whether you’re wearing a safety belt or not. But you can unbuckle a safety belt, even if you’re upside down.
Page 25: How To Wear Safety Belts Properly
How to Wear Safety Belts Properly Adults This part is only for people of adult size. Be aware that there are special things to know about safety belts and children. And there are different rules for smaller children and babies. If a child will be riding in your vehicle, see the part of this manual called “Children.”...
Page 26 4. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. If the belt isn’t long enough, see “Safety Belt Extender” at the end of this section. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.
Page 27 What’s wrong with this? The shoulder belt is too loose. It won’t give nearly as much protection this way. CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit against your body.
Page 28 What’s wrong with this? The belt is buckled in the wrong place. 1-16 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 29 What’s wrong with this? The shoulder belt is worn under the arm. It should be worn over the shoulder at all times. CAUTION: You can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would move too far forward, which would increase the chance of head and neck injury.
Page 30 What’s wrong with this? The belt is twisted across the body. 1-18 CAUTION: You can be seriously injured by a twisted belt. In a crash, you wouldn’t have the full width of the belt to spread impact forces. If a belt is twisted, make it straight so it can work properly, or ask your dealer to fix it.
Page 31: Safety Belt Use During Pregnancy
To unlatch the belt, just push the button on the buckle. The belt should go back out of the way. Before you close the door, be sure the belt is out of the way. If you slam the door on it, you can damage both the belt and your vehicle.
Page 32: Right Front Passenger Position
The best way to protect the fetus is to protect the mother. When a safety belt is worn properly, it’s more likely that the fetus won’t be hurt in a crash. For pregnant women, as for anyone, the key to making safety belts effective is wearing them properly.
Page 33 CAUTION: Air bags inflate with great force, faster than the blink of an eye. If you’re too close to an inflating air bag, 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 34 How the Air Bag System Works Where are the air bags? The driver’s air bag is in the middle of the steering wheel. 1-22 The right front passenger’s air bag is in the instrument panel on the passenger’s side.
Page 35 CAUTION: If something is between an occupant and an air bag, the bag might not inflate properly or it might force the object into that person. The path of an inflating air bag must be kept clear. Don’t put anything between an occupant and an air bag, and don’t attach or put anything on the steering wheel hub or on or near any other air bag covering.
Page 36 How does an air bag restrain? In moderate to severe frontal or near frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. Air bags supplement the protection provided by safety belts. Air bags distribute the force of the impact more evenly over the occupant’s upper body, stopping the occupant more gradually.
Page 37 Air bags are designed to inflate only once. After they inflate, you’ll need some new parts for your air bag system. If you don’t get them, the air bag system won’t be there to help protect you in another crash. A new system will include air bag modules and possibly other parts.
Page 38 CAUTION: For up to two minutes after the ignition key is turned off and the battery is disconnected, an air bag can still inflate during improper service. You can be injured if you are close to an air bag when it inflates.
Page 39: Rear Seat Passengers
Rear Seat Passengers It’s very important for rear seat passengers to buckle up! Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts. Rear passengers who aren’t safety belted can be thrown out of the vehicle in a crash.
Page 40 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 41 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’d be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen.
Page 42: Rear Safety Belt Comfort Guides For Children And Small Adults
Rear Safety Belt Comfort Guides for Children and Small Adults Rear shoulder belt comfort guides will provide added safety belt comfort for children who have outgrown child restraints and for small adults. When installed on a shoulder belt, the comfort guide pulls the belt away from the neck and head.
Page 43 1. Pull the elastic cord out from between the edge of the seatback and the interior body to remove the guide from its storage clip. 2. Slide the guide under and past the belt. The elastic cord must be under the belt. Then, place the guide over the belt, and insert the two edges of the belt into the slots of the guide.
Page 44 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. 1-32 4. Buckle, position and release the safety belt as described in “Rear Seat Outside Passenger Positions” earlier in this section.
Page 45: Center Rear Passenger Position
Center Rear Passenger Position Lap Belt When you sit in the center rear seating position, you have a lap safety belt which has a retractor. 1. Pick up the latch plate and pull the belt across you. Don’t let it get twisted. 2.
Page 46: Children
4. Position and release it the same way as the lap part of a lap shoulder belt. If the belt isn’t long enough, see “Safety Belt Extender” at the end of this section. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.
Page 47 CAUTION: Smaller children and babies should always be restrained in a child or infant restraint. The instructions for the restraint will say whether it is the right type and size for your child. A very young child’s hip bones are so small that a regular belt might not stay low on the hips, as it should.
Page 48 CAUTION: Never hold a baby in your arms while riding in a vehicle. A baby doesn’t weigh much crash. During a crash a baby will become so heavy you can’t hold it. For example, in a crash CAUTION: (Continued) 1-36 CAUTION: (Continued) at only 25 mph (40 km/h), a 12 will suddenly become a 240...
Page 49: Child Restraints
Child Restraints Every time infants and young children ride in vehicles, they should have protection provided by appropriate restraints. What are the different types of add child restraints? on child restraints are available in four basic types. When selecting a child restraint, take into consideration not only the child’s weight and size, but also whether or not the restraint will be compatible with the motor vehicle in which it will...
Page 50 A rear facing infant restraint (B) positions an infant to face the rear of the vehicle. Rear facing infant restraints are designed for infants of up to about 20 lbs. (9 kg) and about one year of age. This type of restraint faces the rear so that the infant’s head, neck and body can have the support they need in a frontal crash.
Page 51 A forward facing child restraint (C E) positions a child upright to face forward in the vehicle. These forward facing restraints are designed to help protect children who are from 20 to 40 lbs. (9 to 18 kg) and about 26 to 40 inches (66 to 102 cm) in height, or up to around four years of age.
Page 52: Where To Put The Restraint
A booster seat (F) is designed for children who are about 40 to 60 lbs., or even up to 80 lbs. (18 to 27 kg, or even up to 36 kg), and about four to eight years of age. A booster seat is designed to improve the fit of the vehicle’s safety belt system.
Page 53: Top Strap
CAUTION: A child in a rear facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear facing child restraint would be very close to the inflating air bag. Always secure a rear facing child restraint in a rear seat outside position.
Page 54: Securing A Child Restraint In A Rear Outside Seat Position
Anchor brackets for the rear outside seat positions are located on the floor in the cargo area of your vehicle. Don’t use the rear set of tie down brackets. Anchor the top strap to the closest bracket on the same side of the vehicle as the child restraint.
Page 55 3. Buckle the belt. Make sure the release button is 4. Pull the rest of the shoulder belt all the way out of positioned so you would be able to unbuckle the the retractor to set the lock. safety belt quickly if you ever had to. 1-43...
Page 56: Center Seat Position
5. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. If you’re using a forward restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt.
Page 57: Front Seat Position
Securing a Child Restraint in the Right Front Seat Position Your vehicle has a right front passenger air bag. Never put a rear facing child restraint in this seat. Here’s why: CAUTION: A child in a rear facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates.
Page 58 3. Pick up the latch plate, and run the lap and shoulder portions of the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how. If the shoulder belt goes in front of the child’s face or neck, put it behind the child restraint.
Page 59: Larger Children
6. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. You may find it helpful to use your knee to push down on the child restraint as you tighten the belt. 7.
Page 60 Accident statistics show that children are safer if they are restrained in the rear seat. But they need to use the safety belts properly. Children who aren’t buckled up can be thrown out in a crash. Children who aren’t buckled up can strike other people who are.
Page 61 CAUTION: Never do this. Here a child is sitting in a seat that has a shoulder belt, but the shoulder part is behind the child. If the child wears the belt in this way, in a crash the child might slide under the belt. The belt’s force would then be applied right on the child’s abdomen.
Page 62: Safety Belt Extender
Safety Belt Extender If the vehicle’s safety belt will fasten around you, you should use it. But if a safety belt isn’t long enough to fasten, your dealer will order you an extender. It’s free. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you.
Page 63 Section 2 Features and Controls Here you can learn about the many standard and optional features on your vehicle, and information on starting, shifting and braking. Also explained are the instrument panel and the warning systems that tell you if everything is working properly and what to do if you have a problem.
Page 64 Keys CAUTION: Leaving children in a vehicle with the ignition key is dangerous for many reasons. A child or others could be badly injured or even killed. They could operate the power windows or other controls or even make the vehicle move. Don’t leave the keys in a vehicle with children.
Page 65 This vehicle has one double the ignition and door locks. It will fit with either side up. When a new vehicle is delivered, the dealer provides the owner with a pair of identical keys and a key code number. The key code number tells your dealer or a qualified sided key for locksmith how to make extra keys.
Page 66: Door Locks
Door Locks CAUTION: Unlocked doors can be dangerous. Passengers especially children open the doors and fall out. When a door is locked, the inside handle won’t open it. Outsiders can easily enter through an unlocked door when you slow down or stop your vehicle. This may not be so obvious: You increase the chance of being thrown out of the vehicle in a crash if the doors aren’t locked.
Page 67: Power Door Locks
Power Door Locks The power door lock switch is located on the armrest. Remove the ignition key and press LOCK to lock all the doors at once. To unlock the doors, press the raised area next to the key symbol. The switch on each rear door works only that door’s lock.

Keyless Entry System You can lock and unlock your doors or liftgate from about 3 feet (1 m) up to 30 feet (9 m) away using the remote keyless entry transmitter supplied with your vehicle.
Page 69: Battery Replacement
Operation UNLOCK: Pressing this button once will unlock the driver’s door. The parking lamps will flash and the interior lights will come on. Pressing this button once also unlocks the rear liftglass. Pressing UNLOCK again within three seconds will cause the remaining doors, including the liftgate, to unlock.
Page 70 NOTICE: When replacing the battery, use care not to touch any of the circuitry. Static from your body transferred to these surfaces may damage the transmitter. To replace the battery in the remote keyless entry transmitter: 1. Insert a dime in the slot between the covers of the transmitter housing near the key ring hole.
Page 71: Liftgate Release
Liftgate/Liftglass CAUTION: It can be dangerous to drive with the liftgate or liftglass open because carbon monoxide (CO) gas can come into your vehicle. You can’t see or smell CO. It can cause unconsciousness and even death. If you must drive with the liftgate or liftglass open or if electrical wiring or other cable connections must pass through the seal between the body and the liftgate or liftglass:...
Page 72 Emergency Release for Opening Liftgate 1. Peel back or slit the carpet locally to expose the access hole in the trim panel. 2. Use a thin screwdriver to reach through the access holes in both the trim panel and the hardware cover.
Page 73 Key in the Ignition If you leave your vehicle with the keys inside, it’s an easy target for joy riders or professional thieves don’t do it. When you park your vehicle and open the driver’s door, you’ll hear a chime reminding you to remove your key from the ignition and take it with you.
Page 74: Testing The Alarm
Remember, the theft deterrent system won’t activate if you lock the doors with a key or use the manual door lock. It activates only if you use a power door lock switch with the door open, or with the remote keyless entry transmitter.
Page 75 Passlock at this time. You may also want to check the fuse (see “Fuses and Circuit Breakers” in the Index). See your dealer for service. In an emergency, call the GMC Roadside Assistance Center at 1 8782.
Page 76: Ignition Positions
Ignition Positions Use the key to turn the ignition switch to five different positions. ACCESSORY (A): This position lets you use things like the radio and the windshield wipers when the engine is off. Push in the key and turn it toward you. Your steering wheel will remain locked, just as it was before you inserted the key.
Page 77: Starting Your Engine
OFF (C): This position lets you turn off the engine but still turn the steering wheel. Use OFF if you must have your vehicle in motion while the engine is off (for example, if your vehicle is being towed). RUN (D): This is the position for driving. START (E): This position starts your engine.
Page 78 NOTICE: Holding your key in START for longer than 15 seconds at a time will cause your battery to be drained much sooner. And the excessive heat can damage your starter motor. Wait about 15 seconds between each try to help avoid draining your battery or damaging your starter.
Page 79: To Use The Engine Coolant Heater
Engine Coolant Heater (If Equipped) In very cold weather, 0 _ F ( 18 _ C) or colder, the engine coolant heater can help. You’ll get easier starting and better fuel economy during engine warm the coolant heater should be plugged in a minimum of four hours prior to starting your vehicle.
Page 80: Automatic Transmission Operation
Automatic Transmission Operation There are several different positions for your shift lever. PARK (P): This locks your rear wheels. It’s the best position to use when you start your engine because your vehicle can’t move easily. CAUTION: It is dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set.
Page 81 NEUTRAL (N): In this position, your engine doesn’t connect with the wheels. To restart when you’re already moving, use NEUTRAL (N) only. CAUTION: Shifting out of PARK (P) or NEUTRAL (N) while your engine is “racing” (running at high speed) is dangerous.
Page 82 FIRST (1): This position gives you even more power but lower fuel economy than SECOND (2). You can use it on very steep hills, or in deep snow or mud. If the selector lever is put in FIRST (1) while the vehicle is moving forward, the transmission won’t shift into first gear until the vehicle is going slowly enough.
Page 83 Four Wheel Drive Because your vehicle has four wheel drive, you can send your engine’s driving power to all four wheels for extra traction. To get the most satisfaction out of four wheel drive, you must be familiar with its operation.
Page 84 2HI: This setting is for driving in most street and highway situations. Your front axle is not engaged in wheel drive. This setting also provides the best fuel economy. AUTO 4WD: This setting is ideal for use when road conditions are variable. When driving your vehicle in AUTO 4WD, the front axle is engaged, but the vehicle’s power is sent to the rear wheels.
Page 85 If the SERVICE 4WD light stays on, you should take your vehicle to your dealer for service. See “Service 4WD” in the Index for further information. Shifting to 4HI or AUTO 4WD Press and release the 4HI or AUTO 4WD switch. This can be done at any speed and the indicator light will flash while shifting.
Page 86 Shifting to NEUTRAL To shift the transfer case to NEUTRAL first make sure the vehicle is parked so that it will not roll: 1. Set the parking brake. 2. Start the vehicle. 3. Connect the vehicle to the towing vehicle. 4.

Page 89: Torque Lock
Leaving Your Vehicle With the Engine Running CAUTION: It can be dangerous to leave your vehicle with the engine running. Your vehicle could move suddenly if the shift lever is not fully in PARK (P) with the parking brake firmly set. And, if you leave the vehicle with the engine running, it could overheat and even catch fire.
Page 90: Parking Over Things That Burn
Shifting Out of PARK (P) Your vehicle has an automatic transmission shift lock control system. You have to fully apply your regular brake before you can shift from PARK (P) when the ignition is in RUN. See “Automatic Transmission Operation” in the Index. If you cannot shift out of PARK (P), ease pressure on the shift lever push the shift lever all the way into...
Page 91: Engine Exhaust
Engine Exhaust CAUTION: Engine exhaust can kill. It contains the gas carbon monoxide (CO), which you can’t see or smell. It can cause unconsciousness and death. You might have exhaust coming in if: Your exhaust system sounds strange or different. Your vehicle gets rusty underneath.
Page 92: Power Windows
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. Your vehicle can roll. Don’t leave your vehicle when the engine is running unless you have to. If you’ve left the engine running, the vehicle can move suddenly.

Page 102: Daytime Running Lamps
There is a delay in the transition between the daytime and nighttime operation of the Daytime Running Lamps (DRL) and the automatic headlamp systems so that driving under bridges or bright overhead street lights does not affect the system. The DRL and automatic headlamp system will only be affected when the light sensor sees a change in lighting lasting longer than the delay.
Page 103: Interior Lamps
The DRL system on your vehicle will turn off temporarily while the turn signals are activated. To idle your vehicle with the DRL off, put your vehicle’s transmission in PARK (P). The DRL will stay off until you shift out of PARK (P). As with any vehicle, you should turn on the regular headlamp system when you need it.
Page 104: Exit Lighting
Exit Lighting With exit lighting, the interior lamps will come on when you remove the key from the ignition. If the DOME OVERRIDE button is in the “out” position, these lights will stay on for a short period of time and then will go out.
Page 105 Mirrors Electrochromic Day/Night Inside Rearview Mirror This mirror automatically changes to reduce glare from headlamps behind you. A photocell on the back of the mirror senses when it is becoming dark outside. Another photocell built into the mirror surface senses when headlamps are behind you.

Page 162: Understanding Radio Reception
Understanding Radio Reception The range for most AM stations is greater than for FM, especially at night. The longer range, however, can cause stations to interfere with each other. AM can pick up noise from things like storms and power lines. Try reducing the treble to reduce this noise if you ever get it.
Page 163: Care Of Your Cassette Tape Player
Care of Your Cassette Tape Player A tape player that is not cleaned regularly can cause reduced sound quality, ruined cassettes or a damaged mechanism.

Page 165 Section 4 Your Driving and the Road Here you’ll find information about driving on different kinds of roads and in varying weather conditions. We’ve also included many other useful tips on driving. Your Driving, the Road and Your Vehicle Defensive Driving Drunken Driving Control of a Vehicle Braking...
Page 166: Your Driving, The Road And Your Vehicle
Your Driving, the Road and Your Vehicle Whenever we drive, we’re taking on an important responsibility. This is true for any motor vehicle passenger car, van, truck or sport utility. Driver behavior, the driving environment, and the vehicle’s design all affect how well a vehicle performs. But statistics show that the most important factor, by far, is how we drive.
Page 167: Vehicle Design
Vehicle Design According to the U.S. Department of Transportation, utility vehicles have a significantly higher rollover rate than other types of vehicles. Utility vehicles do have a higher ground clearance and a narrower track or shorter wheelbase than passenger cars to make them more capable for off road driving.
Page 168: Drunken Driving
Drunken Driving Death and injury associated with drinking and driving is a national tragedy. It’s the number one contributor to the highway death toll, claiming thousands of victims every year. Alcohol affects four things that anyone needs to drive a vehicle: Judgment Muscular Coordination Vision...
Page 169 It’s the amount of alcohol that counts. For example, if the same person drank three double martinis (3 ounces or 90 ml of liquor each) within an hour, the person’s BAC would be close to 0.12 percent. A person who consumes food just before or during drinking will have a somewhat lower BAC level.
Page 170 The body takes about an hour to rid itself of the alcohol in one drink. No amount of coffee or number of cold showers will speed that up. “I’ll be careful” isn’t the right answer. What if there’s an emergency, a need to take sudden action, as when a child darts into the street? A person with even a moderate BAC might not be able to react quickly enough to avoid the collision.
Page 171: Control Of A Vehicle
Control of a Vehicle You have three systems that make your vehicle go where you want it to go. They are the brakes, the steering and the accelerator. All three systems have to do their work at the places where the tires meet the road. Sometimes, as when you’re driving on snow or ice, it’s easy to ask more of those control systems than the tires and road can provide.
Page 172: Anti-Lock Brakes (Abs)
Avoid needless heavy braking. Some people drive in spurts heavy acceleration followed by heavy braking rather than keeping pace with traffic. This is a mistake. Your brakes may not have time to cool between hard stops. Your brakes will wear out much faster if you do a lot of heavy braking.
Page 173 Here’s how anti lock works. Let’s say the road is wet. You’re driving safely. Suddenly an animal jumps out in front of you. You slam on the brakes. Here’s what happens with ABS. A computer senses that wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each front wheel and at both rear wheels.
Page 174: Steering
Remember: Anti lock doesn’t change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you won’t have time to apply your brakes if that vehicle suddenly slows or stops.
Page 175: Steering In Emergencies
What should you do if this ever happens? Ease up on the accelerator pedal, steer the vehicle the way you want it to go, and slow down. Speed limit signs near curves warn that you should adjust your speed. Of course, the posted speeds are based on good weather and road conditions.
Page 176: Off - Road Recovery
An emergency like this requires close attention and a quick decision. If you are holding the steering wheel at the recommended 9 and 3 o’clock positions, you can turn it a full 180 degrees very quickly without removing either hand. But you have to act fast, steer quickly, and just as quickly straighten the wheel once you have avoided the object.
Page 177: Passing
Passing The driver of a vehicle about to pass another on a lane highway waits for just the right moment, accelerates, moves around the vehicle ahead, then goes back into the right lane again. A simple maneuver? Not necessarily! Passing another vehicle on a two highway is a potentially dangerous move, since the passing vehicle occupies the same lane as oncoming traffic for several seconds.
Page 178: Loss Of Control
Check your mirrors, glance over your shoulder and start your left lane change signal before moving out of the right lane to pass. When you are far enough ahead of the passed vehicle to see its front in your inside mirror, activate your right lane change signal and move back into the right lane.
Page 179: Off - Road Driving With Your
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 180 Before You Go Off-Roading There are some things to do before you go out. For example, be sure to have all necessary maintenance and service work done. Check to make sure all underbody shields (if so equipped) are properly attached. Be sure you read all the information about your four wheel drive vehicle in this manual.
Page 181: Environmental Concerns
Environmental Concerns road driving can provide wholesome and satisfying recreation. However, it also raises environmental concerns. GMC recognizes these concerns and urges every off roader to follow these basic rules for protecting the environment: Always use established trails, roads and areas that have been specially set aside for public off recreational driving;...
Page 182: Scanning The Terrain
Controlling your vehicle is the key to successful road driving. One of the best ways to control your vehicle is to control your speed. Here are some things to keep in mind. At higher speeds: you approach things faster and you have less time to scan the terrain for obstacles.
Page 183: Approaching A Hill
When you drive over obstacles or rough terrain, keep a firm grip on the steering wheel. Ruts, troughs or other surface features can jerk the wheel out of your hands if you’re not prepared. When you drive over bumps, rocks, or other obstacles, your wheels can leave the ground.
Page 184: Driving Uphill
On a large hill, the incline may get steeper as you near the top, but you may not see this because the crest of the hill is hidden by bushes, grass or shrubs. Here are some other things to consider as you approach a hill.
Page 185 Ease up on your speed as you approach the top of the hill. Attach a flag to the vehicle to make you more visible to approaching traffic on trails or hills. Sound the horn as you approach the top of the hill to let opposing traffic know you’re there.
Page 186 Here are some things you must not do if you stall, or are about to stall, when going up a hill. Never attempt to prevent a stall by shifting into NEUTRAL (N) to “rev up” the engine and regain forward momentum. This won’t work. Your vehicle will roll backwards very quickly and you could go out of control.
Page 187: Driving Downhill
Driving Downhill When off roading takes you downhill, you’ll want to consider a number of things: How steep is the downhill? Will I be able to maintain vehicle control? What’s the surface like? Smooth? Rough? Slippery? Hard packed dirt? Gravel? Are there hidden surface obstacles? Ruts? Logs? Boulders? What’s at the bottom of the hill? Is there a hidden...
Page 188: Driving Across An Incline
Am I likely to stall when going downhill? It’s much more likely to happen going uphill. But if it happens going downhill, here’s what to do. Stop your vehicle by applying the regular brakes. Apply the parking brake. Shift to PARK (P) and, while still braking, restart the engine.
Page 189: Stalling On An Incline
CAUTION: Driving across an incline that’s 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, don’t drive across it. Find another route instead. What if I’m driving across an incline that’s not too steep, but I hit some loose gravel and start to slide downhill.
Page 190 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. Driving in Mud, Sand, Snow or Ice When you drive in mud, snow or sand, your wheels won’t get good traction.
Page 191: Driving In Water
Driving in Water Light rain causes no special off road driving problems. But 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’s deep enough to cover your wheel hubs, axles or exhaust pipe, don’t try it you probably won’t get through.
Page 192: 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 193 Here are some tips on night driving. Drive defensively. Don’t drink and drive. Since you can’t see as well, you may need to slow down and keep more space between you and other vehicles. Slow down, especially on higher speed roads. Your headlamps can light up only so much road ahead.
Page 194: Driving In Rain And On Wet Roads
Driving in Rain and on Wet Roads Rain and wet roads can mean driving trouble. On a wet road, you can’t stop, accelerate or turn as well because your tire road traction isn’t as good as on dry roads. And, if your tires don’t have much tread left, you’ll get even less traction.
Page 195 Driving too fast through large water puddles or even going through some car washes can cause problems, too. The water may affect your brakes. Try to avoid puddles. But if you can’t, try to slow down before you hit them. CAUTION: Wet brakes can cause accidents.
Page 196: Driving Through Flowing Water
Hydroplaning usually happens at higher speeds. There just isn’t a hard and fast rule about hydroplaning. The best advice is to slow down when it is raining. 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.
Page 197: City Driving
City Driving One of the biggest problems with city streets is the amount of traffic on them. You’ll want to watch out for what the other drivers are doing and pay attention to traffic signals. Here are ways to increase your safety in city driving: Know the best way to get to where you are going.
Page 198: 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. 4-34 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.

If it needs service, have it done before starting out. Of course, you’ll find experienced and able service experts in GMC dealerships all across North America. They’ll be ready and willing to help if you need it.
Page 200: 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 201 If you drive regularly in steep country, or if you’re planning to visit there, here are some tips that can make your trips safer and more enjoyable. (See “Off Driving” in the Index for information about driving off road.) Keep your vehicle in good shape. Check all fluid levels and also the brakes, tires, cooling system and transmission.
Page 202: Winter Driving
Winter Driving Here are some tips for winter driving: Have your vehicle in good shape for winter. You may want to put winter emergency supplies in your vehicle. 4-38 Include an ice scraper, a small brush or broom, a supply of windshield washer fluid, a rag, some winter outer clothing, a small shovel, a flashlight, a red cloth and reflective warning triangles.
Page 203 What’s the worst time for this? “Wet ice.” Very cold snow or ice can be slick and hard to drive on. But wet ice can be even more trouble because it may offer the least traction of all. You can get wet ice when it’s about freezing (32 F;...
Page 204 If You’re Caught in a Blizzard If you are stopped by heavy snow, you could be in a serious situation. You should probably stay with your vehicle unless you know for sure that you are near help and you can hike through the snow. Here are some things to do to summon help and keep yourself and your passengers safe: Turn on your hazard flashers.
Page 205: Recreational Vehicle Towing
CAUTION: Snow can trap exhaust gases under your vehicle. This can cause deadly CO (carbon monoxide) gas to get inside. CO could overcome you and kill you. You can’t see it or smell it, so you might not know it is in your vehicle. Clear away snow from around the base of your vehicle, especially any that is blocking your exhaust pipe.
Page 206 Four-Wheel-Drive Vehicles Use the following procedure to correctly tow your vehicle on all four wheels: 1. Firmly set the parking brake. 2. Place the transmission in PARK (P). 3. Securely attach the vehicle being towed to the tow vehicle. 4-42 4.
Page 207: Loading Your Vehicle
Loading Your Vehicle The Certification/Tire label is found on the driver’s door edge, above the door latch. The label shows the size of your original tires and the inflation pressures needed to obtain the gross weight capacity of your vehicle. This is called the Gross Vehicle Weight Rating (GVWR).
Page 208 Using heavier suspension components to get added durability might not change your weight ratings. Ask your dealer to help you load your vehicle the right way. NOTICE: Your warranty does not cover parts or components that fail because of overloading. If you put things inside your vehicle tools, packages, or anything else as the vehicle goes.
Page 209 Payload The payload capacity is shown on the Certification/Tire label. This is the maximum load capacity that your vehicle can carry. Be sure to include the weight of the occupants as part of your load. If you added any accessories or equipment after your vehicle left the factory, remember to subtract the weight of these things from the payload.
Page 210: Towing A Trailer
Add-On Equipment When you carry removable items, you may need to put a limit on how many people you carry inside your vehicle. Be sure to weigh your vehicle before you buy and install the new equipment. NOTICE: Your warranty doesn’t cover parts or components that fail because of overloading.
Page 211: If You Do Decide To Pull A Trailer
If yours was built with trailering options, as many are, it’s ready for heavier trailers. But trailering is different than just driving your vehicle by itself. Trailering means changes in handling, durability and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly.
Page 212 Tow/Haul Mode The Tow/Haul Mode is a feature that assists when pulling a heavy trailer. The purpose of the Tow/Haul Mode is: Reduce the frequency of shifts when pulling a heavy trailer. Provide the same shift feel when pulling a heavy trailer as when the vehicle is unloaded.
Page 213: Weight Of The Trailer
Weight of the Trailer How heavy can a trailer safely be? It depends on how you plan to use your rig. For example, speed, altitude, road grades, outside temperature and how much your vehicle is used to pull a trailer are all important. And, it can also depend on any special equipment that you have on your vehicle.
Page 214 If you’re using a weight carrying hitch, the trailer tongue (A) should weigh 10 percent of the total loaded trailer weight (B). If you’re using a weight hitch, the trailer tongue (A) should weigh 12 percent of the total loaded trailer weight (B). After you’ve loaded your trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper.
Page 215: 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 216: 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 can’t see or smell CO. It can cause unconsciousness or death.
Page 217: Following Distance
Following Distance Stay at least twice as far behind the vehicle ahead as you would when driving your vehicle without a trailer. This can help you avoid situations that require heavy braking and sudden turns. Passing You’ll need more passing distance up ahead when you’re towing a trailer.
Page 218: Turn Signals When Towing A Trailer
Turn Signals When Towing a Trailer When you tow a trailer, your vehicle has to have extra wiring and a heavy duty turn signal flasher. 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.

Press the button on top of the steering column all the way down to make your front and rear turn signal lamps flash on and off.
Page 223: Other Warning Devices
Other Warning Devices If you carry reflective triangles, you can set one up at the side of the road about 300 feet (100 m) behind your vehicle. Jump Starting If your battery has run down, you may want to use another vehicle and some jumper cables to start your vehicle.
Page 224 2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles aren’t touching each other. If they are, it could cause a ground connection you don’t want. You wouldn’t be able to start your vehicle, and the bad grounding could damage the electrical systems.
Page 225 5. Check that the jumper cables don’t have loose or missing insulation. If they do, you could get a shock. The vehicles could be damaged too. Before you connect the cables, here are some basic things you should know. Positive (+) will go to positive (+) and negative ( ) will go to a heavy, unpainted metal engine part.
Page 226 Don’t let the other end touch anything until the next step. The other end of the negative cable doesn’t go to the dead battery. It goes to a heavy unpainted metal part on the engine of the vehicle with the dead battery.

Removal Procedure A. Heavy Unpainted, Metal Engine Part B. Good Battery C. Dead Battery Towing Your Vehicle CAUTION: To help avoid serious personal injury to you or others: Never let passengers ride in a vehicle that is being towed. Never tow faster than safe or posted speeds. Never tow with damaged parts not fully secured.
Page 228: Engine Overheating
NOTICE: Use the proper towing equipment to avoid damage to the bumper, fascia or fog lamp areas of the vehicle. With current trends in automotive styles and design, it is essential that the correct towing equipment is used to tow a vehicle. Your vehicle can be towed with with wheel lift or car carrier equipment.
Page 229 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. Just turn it off and get everyone away from the vehicle until it cools down.
Page 230: If No Steam Is Coming From Your Engine
If No Steam Is Coming From Your Engine If you get an engine overheat warning but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you: Climb a long hill on a hot day. Stop after high speed driving.
Page 231: Cooling System
Cooling System When you decide it’s safe to lift the hood, here’s what you’ll see: A. Coolant Recovery Tank B. Radiator Pressure Cap C. Engine Fan If the coolant inside the coolant recovery tank is boiling, don’t do anything else until it cools down. When the engine is cold, the coolant level should be at least up to the ADD mark.
Page 232 CAUTION: Heater and radiator hoses, and other engine parts, can be very hot. Don’t touch them. If you do, you can be burned. Don’t run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned.
Page 233: Recovery Tank
How to Add Coolant to the Coolant Recovery Tank If you haven’t found a problem yet, but the coolant level isn’t at the ADD mark, add a 50/50 mixture of clean, drinkable water and DEX COOL the coolant recovery tank. (See “Engine Coolant” in the Index for more information.) CAUTION: Adding only plain water to your cooling system...
Page 234 5-14 CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Don’t spill coolant on a hot engine. When the coolant in the coolant recovery tank is at the ADD mark, start your vehicle.
Page 235 CAUTION: Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the radiator pressure cap even a little they can come out at high speed. Never turn the cap when the cooling system, including the radiator pressure cap, is hot.
Page 236: How To Add Coolant To The Radiator
How to Add Coolant to the Radiator 1. You can remove the radiator pressure cap when the cooling system, including the radiator pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise until it first stops.

Page 276: Radiator Pressure Cap
CAUTION: Turning the radiator pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. With the coolant recovery tank, you will almost never have to add coolant at the radiator. Never turn the radiator pressure cap little when the engine and radiator are hot.
Page 277: Power Steering Fluid
Power Steering Fluid 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 278: Adding Washer Fluid
Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure to read the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing.
Page 279: Brake Fluid
Brakes Brake Fluid Your brake master cylinder reservoir is here. It is filled with 3 brake fluid. 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 280 Checking Brake Fluid You can check the brake fluid without taking off the cap. Just look at the brake fluid reservoir. The fluid level should be above MIN. If it isn’t, have your brake system checked to see if there is a leak. After work is done on the brake hydraulic system, make sure the level is above the MIN but not over the MAX mark.
Page 281: Brake Wear
NOTICE: Using the wrong fluid can badly damage brake system parts. For example, just a few drops of mineral based oil, such as engine oil, in your brake system can damage brake system parts so badly that they’ll have to be replaced.
Page 282: Brake Adjustment
Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes. Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly torque wheel nuts in the proper sequence to GM specifications.

Page 290 Inflation -- Tire Pressure The Certification/Tire label, which is on the driver’s door edge, above the door latch, shows the correct inflation pressures for your tires when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). NOTICE: Don’t let anyone tell you that underinflation or overinflation is all right.
Page 291: Tire Inspection And Rotation
Tire Inspection and Rotation Tires should be rotated every 6,000 to 8,000 miles (10 000 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’s Time for New Tires”...
Page 292 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 293: Buying New Tires
Buying New Tires To find out what kind and size of tires you need, look at the Certification/Tire label. The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) number on each tire’s sidewall. When you get new tires, get ones with that same TPC Spec number.
Page 294: Uniform Tire Quality Grading
Uniform Tire Quality Grading The following information relates to the system developed by the United States National Highway Traffic Safety Administration, which grades tires by treadwear, traction and temperature performance. (This applies only to vehicles sold in the United States.) The grades are molded on the sidewalls of most passenger car tires.
Page 295: Wheel Replacement
Temperature A, B, C The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure.
Page 296 Each new wheel should have the same load capacity, diameter, width, offset and be mounted the same way as the one it replaces. If you need to replace any of your wheels, wheel bolts or wheel nuts, replace them only with new GM original equipment parts.
Page 297: Tire Chains
Tire Chains NOTICE: Don’t use tire chains. They can damage your vehicle because there’s not enough clearance. Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination and road conditions.
Page 298: Cleaning The Inside Of Your Vehicle
Don’t use any of these unless this manual says you can. In many uses, these will damage your vehicle: Alcohol Laundry Soap Bleach Reducing Agents Cleaning the Inside of Your Vehicle Use a vacuum cleaner often to get rid of dust and loose dirt.
Page 299: Special Fabric Cleaning Problems
Special Fabric Cleaning Problems Stains caused by such things as catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, vomit, urine and blood can be removed as follows: 1. Carefully scrape off excess stain, then sponge the soiled area with cool water. 2.
Page 300: Care Of Safety Belts
Cleaning the Top of the Instrument Panel Use only mild soap and water to clean the top surfaces of the instrument panel. Sprays containing silicones or waxes may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions.
Page 301: Cleaning Glass Surfaces
Cleaning Glass Surfaces Glass should be cleaned often. GM Glass Cleaner or a liquid household glass cleaner will remove normal tobacco smoke and dust films on interior glass. (See “Appearance Care and Materials” in the Index.) Don’t use abrasive cleaners on glass, because they may cause scratches.
Page 302: Cleaning The Outside Of Your Vehicle
Cleaning the Outside of Your Vehicle The paint finish on your vehicle provides beauty, depth of color, gloss retention and durability. Washing Your Vehicle The best way to preserve your vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water.
Page 303: Cleaning Aluminum Wheels
Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage your vehicle’s finish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non abrasive cleaners that are marked safe for painted surfaces to remove foreign matter.
