How to Use this Manual Safety Warnings and Symbols Many people read their owner’s manual from beginning to end when they first receive their new vehicle. If you do this, it will help you learn about the features and controls for your vehicle. In this manual, you’ll find that pictures and words work together to explain things quickly. You will find a number of safety cautions in this book. We use a box and the word CAUTION to tell you about things that could hurt you if you were to ignore the warning.
You will also find a circle with a slash through it in this book. This safety symbol means “Don’t,” “Don’t do this” or “Don’t let this happen.” In the notice area, we tell you about something that can damage your vehicle. Many times, this damage would not be covered by your warranty, and it could be costly. But the notice will tell you what to do to help avoid the damage. When you read other manuals, you might see CAUTION and NOTICE warnings in different colors or in different words.
Vehicle Symbols These are some of the symbols you may find on your vehicle.

Section 1 Seats and Restraint Systems Here you’ll find information about the seats in your vehicle and how to use your safety belts properly. You can also learn about some things you should not do with air bags and safety belts.
Seats and Seat Controls This section tells you about the seats -- how to adjust them, and fold them up and down. It also tells you about reclining front seatbacks and head restraints. Manual Front Seat CAUTION: You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you don’t want to. Adjust the driver’s seat only when the vehicle is not moving.
Manual Cushion Tilt (If Equipped) Manual Lumbar Control (If Equipped) If your vehicle has a lumbar adjustment, you can increase or decrease lumbar support in an area of the lower seatback. If your vehicle has this feature, you can raise or lower the front of the driver’s or passenger’s seat with this lever located at the inside edge of the seat. To raise or lower the front of the seat, move the lever up or down in a continuous motion until the cushion reaches the desired height.
Power Seat(s) (If Equipped) Raise the front of the seat cushion by raising the forward edge of the button. Lower the front of the seat cushion by lowering the forward edge of the button. Move the seat forward by moving the whole button toward the front of the vehicle. Raise the rear of the seat cushion by raising the rear edge of the button. Lower the rear of the seat cushion by lowering the rear edge of the button. Move the seat rearward by moving the whole button toward the rear of the vehicle.
Power Lumbar Control (If Equipped) Memory Seat (If Equipped) If you have power lumbar adjustment, you can increase or decrease lumbar support in an area of the lower seatback. To increase support, press and hold the front of the control. Let go of the control when the lower seatback reaches the desired level of support. To decrease support, press and hold the rear of the control. Let go of the control when the lower seatback reaches the desired level of support.
Heated Front Seats (If Equipped) Reclining Seatbacks If your vehicle has heated front seats, the ignition must be in RUN for them to operate. The control for the driver’s side heated seat is located on the driver’s side door panel. The control for the passenger’s side heated seat is located on the passenger’s side door panel. To activate the heated seats, press the button once for the HI heat setting. Press the button again for the LO heat setting.
CAUTION: But don’t have a seatback reclined if your vehicle is moving. Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can’t do their job when you’re reclined like this. The shoulder belt can’t do its job. In a crash, you could go into it, receiving neck or other injuries. The lap belt can’t do its job either. In a crash the belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones.
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. Rear Seats CAUTION: If a head restraint is not installed on the seatback or stored in the vehicle properly, it could be thrown about the vehicle in a crash or sudden maneuver. People in the vehicle could be injured.
On Suburban/Yukon XL models with bucket seats, the seatbacks can be reclined. To adjust the seatback, pull the lever located at the base of the back forward. Release the lever to lock the seatback where you want it. Pull the lever again and the seatback will go to an upright position. In order to fold the back of a bucket seat into a horizontal load floor, the back must be in its full upright position and not reclined.
Pull forward on the seatback and up on the seat cushion to make sure the seat is securely in place. Check to see that the buckles on the driver’s side seatback are accessible to the outboard and center occupant and are not under the seat cushions. If you have removed the head restraints to fold the rear bucket seat, be sure to reinstall them on the seatback after it has been returned to the normal seating position. Be sure to return the head restraints to the upright position on Utility models.
Entry to the Third Seat Folding the Third Seat Suburban/Yukon XL: The passenger’s side of the second row 60/40 or rear bucket seats has an easy entry feature. This makes it easy to get in and out of the third seat, if your vehicle has one. Utility: The seatback of the third seat (if equipped) in utility models also folds down on the floor. To operate the easy entry seat, rotate the release lever, located near the back of the seat rearward.
If more cargo space is desired, the third seat can also be folded and tumbled forward or removed if necessary by pulling up on the release lever labeled 2. To return the seat to the passenger position, pull up on the release lever and then pull up on the seatback until it locks into the upright position. Push forward on the seatback to make sure it is locked into position. If still more cargo space is desired, the third seat can also be folded and tumbled forward by using the lever, labeled 2.
Push and pull on the seat, making sure that the support rod is holding it firmly in place. Use the seat in this position only when necessary for additional cargo space. CAUTION: If the support rod isn’t properly engaged, the folded third row seat could come loose in a sudden stop or crash. That could cause injury to people and damage to your vehicle. Always be sure the support rod is properly engaged when the third row seat is folded forward.
To unlatch the seat from the back of the floor, pull up on the release lever labeled 2 at the rear of the seat and lift the rear of the seat up from the floor. Fold the seatback forward into the seat cushion by using the lever labeled 1. The seat cannot be removed unless the seatback is folded. To unlatch the seat from the floor, pull up on the release lever labeled 2 at the rear of the seat and lift the rear of the seat up, off of the floor.
Suburban/Yukon XL: To put the seat back in, place the front of the seat on the load floor, facing the front of the vehicle. While holding the rear of the seat up use the wheels on the front of the seat to roll it towards the seat hooks in the floor. When the latches are engaged in the hooks, let the seat drop into place. Lift up on the carrying handle to make sure the seat is locked in place. Raise the seatback into the upright position. Push and pull on the seat to make sure it is locked into place.
In most states and Canadian provinces, the law says to wear safety belts. Here’s why: They work. 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. Be sure everyone in your vehicle is in a seat and using a safety belt properly.
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.
Get it up to speed. Then stop the vehicle. The rider doesn’t stop. 1-18 The person keeps going until stopped by something. In a real vehicle, it could be the windshield ...
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.
Here Are Questions Many People Ask About Safety Belts -- and the Answers Q: Won’t I be trapped in the vehicle after an accident if I’m wearing a safety belt? A: 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. And your chance of being conscious during and after an accident, so you can unbuckle and get out, is much greater if you are belted.
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.” Follow those rules for everyone’s protection. First, you’ll want to know which restraint systems your vehicle has. We’ll start with the driver position.
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. 5. To make the lap part tight, pull down on the buckle end of the belt as you pull up on the shoulder belt. The lap part of the belt should be worn low and snug on the hips, just touching the thighs.
Q: What’s wrong with this? 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. A: The shoulder belt is too loose. It won’t give nearly as much protection this way.
Q: What’s wrong with this? 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. This could cause serious internal injuries. Always buckle your belt into the buckle nearest you. A: The belt is buckled in the wrong place.
Q: What’s wrong with this? 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. Also, the belt would apply too much force to the ribs, which aren’t as strong as shoulder bones. You could also severely injure internal organs like your liver or spleen. A: The shoulder belt is worn under the arm. It should be worn over the shoulder at all times.
Q: What’s wrong with this? 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. A: The belt is twisted across the body.
Safety Belt Use During Pregnancy Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they don’t wear safety belts. 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.
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. Right Front Passenger Position To learn how to wear the right front passenger’s safety belt properly, see “Driver Position” earlier in this section.
CAUTION: (Continued) Frontal air bags for the driver and right front passenger are designed to work only in moderate to severe crashes where the front of your vehicle hits something. They aren’t designed to inflate at all in rollover, rear, side or low-speed frontal crashes. And, for unrestrained occupants, frontal air bags may provide less protection in frontal crashes than more forceful air bags have provided in the past.
CAUTION: Anyone who is up against, or very close to, any air bag when it inflates can be seriously injured or killed. Air bags plus lap-shoulder belts offer the best protection for adults, but not for young children and infants. Neither the vehicle’s safety belt system nor its air bag system is designed for them. Young children and infants need the protection that a child restraint system can provide. Always secure children properly in your vehicle. To read how, see the part of this manual called “Children.
How the Air Bag Systems Work Where are the air bags? The right front passenger’s frontal air bag is in the instrument panel on the passenger’s side. The driver’s frontal air bag is in the middle of the steering wheel. The driver’s side impact air bag is in the side of the driver’s seatback closest to the door.
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 and don’t let seat covers block the inflation path of a side impact air bag.
When should an air bag inflate? The driver’s and right front passenger’s frontal air bags are designed to inflate in moderate to severe frontal or near-frontal crashes. The frontal air bags are designed to inflate only if the impact speed is above the system’s designed “threshold level.” If your vehicle goes straight into a wall that doesn’t move or deform, the threshold level is about 9 to 16 mph (14 to 26 km/h).
How does an air bag restrain? In moderate to severe frontal or near frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. In moderate to severe side collisions, even belted occupants can contact the inside of the vehicle. The air bag supplements 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.
In many crashes severe enough to inflate an air bag, windshields are broken by vehicle deformation. Additional windshield breakage may also occur from the right front passenger air bag. D Air bags are designed to inflate only once. After an air bag inflates, 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.
Servicing Your Air Bag-Equipped Vehicle Air bags affect how your vehicle should be serviced. There are parts of the air bag systems in several places around your vehicle. Your dealer and the service manual have information about servicing your vehicle and the air bag systems. To purchase a service manual, see “Service and Owner Publications” in the Index.
Q: What if I add a snow plow? Will it keep the air bags from working properly? A: We’ve designed our air bag systems to work properly under a wide range of conditions, including snow plowing with vehicles equipped with the optional Snow Plow Prep Package (RPO VYU). But don’t change or defeat the snow plow’s “tripping mechanism.” If you do, it can damage your snow plow and your vehicle, and it may cause an air bag inflation.
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. And they can strike others in the vehicle who are wearing safety belts. Rear Seat Outside Passenger Positions To make the belt shorter, pull its free end as shown until the belt is snug.
Lap-Shoulder Belt The positions next to the windows have lap-shoulder belts. Here’s how to wear one properly. When the shoulder belt is pulled out all the way, it will lock. If it does, let it go back all the way and start again. If the belt is not long enough, see “Safety Belt Extender” at the end of this section. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 1. Pick up the latch plate and pull the belt across you.
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. 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.
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. There is one guide for each outside passenger position in the rear seat.
Third Row Seat 1. For the second row, remove the guide from its storage clip on the trim panel near the side of the seatback. For the third row, remove the guide from its storage clip on the side of the seatback. 1-42 2. Place the guide over the belt and insert the two edges of the belt into the slots of the guide.
3. Be sure that the belt is not twisted and it lies flat. The guide must be on top of the belt.
Children Everyone in a vehicle needs protection! That includes infants and all children smaller than adult size. 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. Smaller Children and Babies CAUTION: Third Row Seat 4.
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. Instead, the belt will likely be over the child’s abdomen. In a crash, the belt would apply force right on the child’s abdomen, which could cause serious or fatal injuries.
CAUTION: (Continued) at only 25 mph (40 km/h), a 12-lb. (5.5 kg) baby will suddenly become a 240-lb. (110 kg) force on your arms. The baby would be almost impossible to hold. Secure the baby in an infant restraint. CAUTION: Never hold a baby in your arms while riding in a vehicle. A baby doesn’t weigh much -- until a crash. During a crash a baby will become so heavy you can’t hold it.
Child Restraints Every time infants and young children ride in vehicles, they should have protection provided by appropriate restraints. Q: What are the different types of add-on child restraints? A: Add-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 be used.
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. Some infant seats come in two parts -- the base stays secured in the vehicle and the seat part is removable.
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. One type, a convertible restraint, is designed to be used either as a rear-facing infant seat or a forward-facing child seat.
When choosing a child restraint, be sure the child restraint is designed to be used in a vehicle. If it is, it will have a label saying that it meets federal motor vehicle safety standards. Then follow the instructions for the restraint. You may find these instructions on the restraint itself or in a booklet, or both. These restraints use the belt system in your vehicle, but the child also has to be secured within the restraint to help reduce the chance of personal injury.
Where to Put the Restraint Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. We at General Motors therefore recommend that you put your child restraint in a rear seat. Never put a rear-facing child restraint in the right front passenger seat. Here’s why: Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle.
Suburban/Yukon XL models without rear seats: Top strap anchor loops are located at the bottom rear of the front seat cushion for the right front passenger’s position. Suburban/Yukon XL models with rear seats: A child restraint with a top strap should only be used in the second or third row. Don’t use a child restraint with a top strap in the front seat because there’s no place to anchor the top strap.
Suburban/Yukon XL Third Row Seat Utility models: A child restraint with a top strap should only be used in the second row. Don’t use a child restraint with a top strap in the right front passenger’s position or in the third row, because there’s no place to anchor the top strap. Utility Second Row Seat Anchor the top strap to this bracket. Once you have the top strap anchored, you’ll be ready to secure the child restraint itself.
Securing a Child Restraint in a Rear Outside Seat Position 2. 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. 3. 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.
4. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. To remove the child restraint, just 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. Securing a Child Restraint in a Center Rear Seat Position 5. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint.
1. Make the belt as long as possible by tilting the latch plate and pulling it along the belt. 2. Put the restraint on the seat. 3. Run the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how. 1-56 4. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 5. To tighten the belt, pull its free end while you push down on the child restraint.
To remove the child restraint, just unbuckle the vehicle’s safety belt. It will be ready to work for an adult or larger child passenger. Securing a Child Restraint in the Right Front Seat Position Securing a Child Restraint in the Center 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: Don’t use child restraints in this position. The restraints won’t work properly.
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 the rear seat. 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.
5. Pull the rest of the shoulder belt all the way out of the retractor to set the lock. 6. To tighten the belt, feed the shoulder belt back into the retractor while you push down on the child restraint. You may find it helpful to use your knee to push down on the child restraint as you tighten the belt. 7. Push and pull the child restraint in different directions to be sure it is secure. To remove the child restraint, just unbuckle the vehicle’s safety belt and let it go back all the way.
Larger Children If you have the choice, a child should sit next to a window so the child can wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. Accident statistics show that children are safer if they are restrained in the rear seat. But they need to use the safety belts properly. D Children who aren’t buckled up can be thrown out in a crash. D Children who aren’t buckled up can strike other people who are.
CAUTION: Never do this. Here two children are wearing the same belt. The belt can’t properly spread the impact forces. In a crash, the two children can be crushed together and seriously injured. A belt must be used by only one person at a time.
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. The belt’s force would then be applied right on the child’s abdomen. That could cause serious or fatal injuries. Wherever the child sits, the lap portion of the belt should be worn low and snug on the hips, just touching the child’s thighs.
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. The extender will be just for you, and just for the seat in your vehicle that you choose. Don’t let someone else use it, and use it only for the seat it is made to fit.
✍ 1-64 NOTES
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.

After securely closing the door, close the passenger’s side door. Make sure both doors are latched securely.
Content Theft-Deterrent (If Equipped) Your vehicle may be equipped with a Content Theft-Deterrent alarm system. With this system, the SECURITY message will flash as you open the door (if your ignition is off). This message reminds you to activate the theft-deterrent system. Here’s how to do it: 1. Open the door. 2. Lock the door with the power door lock switch or the remote keyless entry transmitter. The SECURITY message should come on and stay on.
Testing the Alarm The alarm can be tested by following these steps: 1. From inside the vehicle, lower the driver’s window and open the driver’s door. 2. Activate the system by locking the doors with the power door lock switch while the door is open, or with the remote keyless entry transmitter. 3. Get out of the vehicle, close the door and wait for the SECURITY message to go out. 4. Then reach in through the window, unlock the door with the manual door lock and open the door. This should set off the alarm.
New Vehicle “Break-In” NOTICE: Your vehicle doesn’t need an elaborate “break-in.” But it will perform better in the long run if you follow these guidelines: D Keep your speed at 55 mph (88 km/h) or less for the first 500 miles (805 km). D Don’t drive at any one speed -- fast or slow -- for the first 500 miles (805 km). Don’t make full-throttle starts. D Avoid making hard stops for the first 200 miles (322 km) or so. During this time your new brake linings aren’t yet broken in.
OFF (C): This position lets you turn off the engine but still turn the steering wheel. It doesn’t lock the steering wheel like LOCK. Use OFF if you must have your vehicle in motion while the engine is off (for example, if your vehicle is being pushed). RUN (D): This is the position for driving. START (E): This position starts your engine.
1. Without pushing the accelerator pedal, turn the ignition key to START. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm. 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. 2.
NOTICE: Engine Coolant Heater (If Equipped) In very cold weather, 0_F (-18_C) or colder, the engine coolant heater can help. You’ll get easier starting and better fuel economy during engine warm-up. Usually, the coolant heater should be plugged in a minimum of four hours prior to starting your vehicle. Your engine is designed to work with the electronics in your vehicle. If you add electrical parts or accessories, you could change the way the engine operates.
CAUTION: Automatic Transmission Operation Plugging the cord into an ungrounded outlet could cause an electrical shock. Also, the wrong kind of extension cord could overheat and cause a fire. You could be seriously injured. Plug the cord into a properly grounded three-prong 110-volt AC outlet. If the cord won’t reach, use a heavy-duty three-prong extension cord rated for at least 15 amps. 4.
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. Your vehicle can roll. Don’t leave your vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured.
To rock your vehicle back and forth to get out of snow, ice or sand without damaging your transmission, see “Stuck: In Sand, Mud, Ice or Snow” in the Index. NEUTRAL (N): In this position, your engine doesn’t connect with the wheels. To restart when you’re already moving, use NEUTRAL (N) only. Also, use NEUTRAL (N) when your two-wheel drive vehicle is being towed. CAUTION: Shifting out of PARK (P) or NEUTRAL (N) while your engine is “racing” (running at high speed) is dangerous.
THIRD (3): This position is also used for normal driving, however it offers more power and lower fuel economy than DRIVE (D). SECOND (2): This position gives you more power but lower fuel economy. You can use SECOND (2) on hills. It can help control your speed as you go down steep mountain roads, but then you would also want to use your brakes off and on. If you manually select SECOND (2) in a light duty automatic transmission, the transmission will drive in second gear.
Tow/Haul Mode Selector Switch Four-Wheel Drive (If Equipped) If your vehicle has four-wheel drive, you can send your engine’s driving power to all four wheels for extra traction. To get the most satisfaction out of four-wheel drive, you must be familiar with its operation. Read the part that follows before using four-wheel drive. See the appropriate text for the transfer case in your vehicle.
Automatic Transfer Case (If Equipped) The transfer case switches are located to the left of the instrument panel cluster. Use these switches to shift into and out of four-wheel drive. You can choose among four driving settings: 2HI: This setting is used for driving in most street and highway situations. Your front axle is not engaged in two-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 only to the rear wheels. When the vehicle senses a loss of traction, the system will automatically engage four-wheel drive. Driving in this mode results in slightly lower fuel economy than 2HI. 4HI: Use 4HI when you need extra traction, such as on snowy or icy roads or in most off-road situations.
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 (except when shifting from 4LO), and the indicator light will flash while shifting. It will remain illuminated when the shift is completed. Shifting to 2HI Press and release the 2HI switch. This can be done at any speed (except when shifting from 4LO).
Shifting to NEUTRAL Shifting Out of NEUTRAL To shift the transfer case to NEUTRAL, first make sure the vehicle is parked so that it will not roll: To shift out of NEUTRAL: 1. Set the parking brake. 2. Shift the transmission to NEUTRAL (N) and turn the ignition to RUN with the engine off. 2. Start the vehicle or turn the ignition to RUN. 3. Connect the vehicle to the towing vehicle. 4. Put the transmission in NEUTRAL (N). 1. Set the parking brake and apply the regular brake pedal. 3.
Parking Brake To set the parking brake, hold the regular brake pedal down with your right foot. Push down the parking brake pedal with your left foot. If the ignition is on, the brake system warning light will flash. A chime will activate when the parking brake is applied and the vehicle is moving at least 3 mph (5 km/h) for at least three seconds. To release the parking brake, hold the regular brake pedal down.
Shifting Into PARK (P) 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. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle won’t move, even when you’re on fairly level ground, use the steps that follow.
Leaving Your Vehicle With the Engine Running CAUTION: D Move the lever up as far as it will go. 3. Be sure the transfer case is in a drive gear -- not in NEUTRAL (N). 4. Turn the ignition key to LOCK. 5. Remove the key and take it with you. If you can leave your vehicle with the ignition key in your hand, your vehicle is in PARK (P). It can be dangerous to leave your vehicle with the engine running.
If you have to leave your vehicle with the engine running, be sure your vehicle is in PARK (P) and the parking brake is firmly set before you leave it. After you move the shift lever into PARK (P), hold the regular brake pedal down. Then, see if you can move the shift lever away from PARK (P) without first pulling it toward you. If you can, it means that the shift lever wasn’t fully locked into PARK (P).
Parking Over Things That Burn Engine Exhaust CAUTION: CAUTION: Things that can burn could touch hot exhaust parts under your vehicle and ignite. Don’t park over papers, leaves, dry grass or other things that can burn. 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: D Your exhaust system sounds strange or different. D Your vehicle gets rusty underneath.
Running Your Engine While You’re Parked It’s better not to park with the engine running. But if ever you have to, here are some things to know. CAUTION: Idling the engine with the climate control system off could allow dangerous exhaust into your vehicle (see the earlier Caution under “Engine Exhaust”). Also, idling in a closed-in place can let deadly carbon monoxide (CO) into your vehicle even if the fan switch is at the highest setting. One place this can happen is a garage.
Level Control (If Equipped) Automatic Level Control Self-Adjusting The automatic level control rear suspension is available on C/K 1500 vehicles and comes as a part of the Autoride suspension. The self-adjusting rear suspension is available on C/K 1500 vehicles and is available with the premium smooth ride suspension package. This type of level control will provide a leveled riding position as well as improved handling under a variety of passenger and loading conditions.
Autoride t (If Equipped) t The Autoride feature will provide a superior vehicle ride and handling under a variety of passenger and loading conditions. The system is fully automatic and uses a computer controller to continuously monitor vehicle speed, wheel to body position, lift/dive and steering position of the vehicle. The controller then sends signals to each shock absorber to independently adjust the damping level to provide the optimum vehicle ride.
The driver’s door has a switch for the passenger windows as well. Your power windows will work when the ignition has been turned to ACCESSORY or RUN or when Retained Accessory Power (RAP) is present. See “Retained Accessory Power” in the Index. Press the rear of the switch with the power window symbol on it to lower the window or the front to raise it. The driver’s window also has an express down feature that allows the window to be lowered without holding the switch.
Turn Signal/Multifunction Lever Turn Signal and Lane Change Signals The turn signal has two upward (for right) and two downward (for left) positions. These positions allow you to signal a turn or a lane change. To signal a turn, move the lever all the way up or down. When the turn is finished, the lever will return automatically. An arrow on the instrument panel will flash in the direction of the turn or lane change.
If a bulb is burned out, replace it to help avoid an accident. If the arrows don’t go on at all when you signal a turn, check for burned-out bulbs and a blown fuse (see “Fuses and Circuit Breakers” in the Index). Flash-To-Pass Feature Turn Signal On Chime To use it, pull the turn signal lever toward you, but not so far that you hear it click. If your turn signal is left on for more than 3/4 of a mile (1.2 km), a chime will sound at each flash of the turn signal.
Windshield Wipers For a single wiping cycle, turn the band to MIST. Hold it there until the wipers start, then let go. The wipers will stop after one wipe. If you want more wipes, hold the band on MIST longer. You can set the wiper speed for a long or short delay between wipes. This can be very useful in light rain or snow. Turn the band to choose the delay time. The closer to LO, the shorter the delay. For steady wiping at low speed, turn the band away from you to the LO position.
Windshield Washer There is a paddle marked with the windshield washer symbol at the top of the multifunction lever. To spray washer fluid on the windshield, push the paddle. The wipers will clear the window and then either stop or return to your preset speed. Rear Window Washer/Wiper This switch is located on the instrument panel. CAUTION: In freezing weather, don’t use your washer until the windshield is warmed. Otherwise the washer fluid can form ice on the windshield, blocking your vision.
Cruise Control With cruise control, you can maintain a speed of about 25 mph (40 km/h) or more without keeping your foot on the accelerator. This can really help on long trips. Cruise control does not work at speeds below about 25 mph (40 km/h). If you apply your brakes, the cruise control will disengage. 2-40 CAUTION: D Cruise control can be dangerous where you D can’t drive safely at a steady speed. So, don’t use your cruise control on winding roads or in heavy traffic.
Setting Cruise Control CAUTION: If you leave your cruise control switch on when you’re not using cruise, you might hit a button and go into cruise when you don’t want to. You could be startled and even lose control. Keep the cruise control switch off until you want to use cruise control. United States Canada The CRUISE light on the instrument panel will illuminate when the cruise control is engaged. Resuming a Set Speed 1. Move the cruise control switch to ON. 2. Get up to the speed you want. 3.
Increasing Speed While Using Cruise Control Passing Another Vehicle While Using Cruise Control There are two ways to go to a higher speed: Use the accelerator pedal to increase your speed. When you take your foot off the pedal, your vehicle will slow down to the cruise control speed you set earlier. D Use the accelerator pedal to get to the higher speed. Press the SET button at the end of the lever, then release the button and the accelerator pedal. You’ll now cruise at the higher speed.
Exterior Lamps Turn the knob clockwise to the master lamps symbol to turn on all the lamps listed as well as the headlamps. Turn the knob all the way counterclockwise to turn off your lamps and put the system into automatic headlamp mode. Rotate the thumbwheel next to the knob up to adjust instrument panel lights. Rotate the thumbwheel up to the first notch to return the radio and gearshift indicator LED display to full intensity when the headlamps or parking lamps are on.
Your vehicle is equipped with a light sensor located on the top of the instrument panel in the defroster grille. Be sure it is not covered, or the system will be on whenever the ignition is on. The system may also turn on your headlamps when driving through a parking garage, heavy overcast weather or a tunnel. This is normal. Lamps On Reminder A reminder chime will sound when your headlamps or parking lamps are manually turned on and your ignition is in OFF, LOCK or ACCESSORY.
When it begins to get dark, the automatic headlamp system will switch from DRL to the headlamps or the last chosen headlamp setting that was used. When you turn the headlamp switch off, the headlamps will go off, and your DRL lamps will illuminate, provided it is not dark outside. To idle an automatic transmission equipped vehicle with the DRL off, set the parking brake. Shifting the transmission into PARK (P) will also allow you to idle the vehicle with the DRL off.
The fog lamps will go off whenever your high-beam headlamps come on. When the high beams go off, the fog lamps will come on again. If your vehicle has this switch, your vehicle may have the Snow Plow Prep Package. For further information see “Snow Plow Prep Package” in the Index. The fog lamps will be cancelled after the ignition is turned off. If you still want to use the fog lamps after you restart the vehicle, you will need to press the fog lamp switch again.

Your vehicle may also have a driver information system that works along with the warning lights and gages. See “Message Center” in the Index. Safety Belt Reminder Light When the key is turned to RUN or START, a chime will come on for about six seconds to remind people to fasten their safety belts, unless the driver’s safety belt is already buckled.
Voltmeter CAUTION: If the air bag readiness light stays on after you start your vehicle, it means the air bag system may not be working properly. The air bags in your vehicle may not inflate in a crash, or they could even inflate without a crash. To help avoid injury to yourself or others, have your vehicle serviced right away if the air bag readiness light stays on after you start your vehicle. United States The air bag readiness light should flash for a few seconds when you turn the ignition key to RUN.
Readings in the low warning zone may occur when a large number of electrical accessories are operating in the vehicle and the engine is left at an idle for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power. Your vehicle’s hydraulic brake system is divided into two parts.
If the light comes on while you are driving, pull off the road and stop carefully. You may notice that the pedal is harder to push. Or, the pedal may go closer to the floor. It may take longer to stop. If the light is still on, have the vehicle towed for service. (See “Towing Your Vehicle” in the Index.) Anti-Lock Brake System Warning Light With the anti-lock brake system, this light will come on when you start your engine and may stay on for several seconds. That’s normal.
Engine Coolant Temperature Gage United States Canada This gage shows the engine coolant temperature. It also provides an indicator of how hard your vehicle is working. During a majority of the operation, the gage will read 210_F (100_C) or less. If you are pulling a load or going up hills, it is normal for the temperature to fluctuate and approach the 250_F (122_C) mark. If the gage reaches the 260_F (125_C) mark, it indicates that the cooling system is working beyond its capacity.
See “Message Center” in the Index for further information. If the transmission fluid reaches temperatures of approximately 275_F (135_C) or greater, the message center will display a TRANS HOT...IDLE ENG warning message. Pull the vehicle off the roadway when it is safe to do so. Set the parking brake, place the transmission in PARK (P) and allow the engine to idle until the transmission temperature falls below 260_F (127_C).
Low Traction Light Traction Off Light If you have the Traction Assist System, this light will come on when the system is limiting wheel spin. See “Traction Assist System” in the Index.

If the light doesn’t come on, have it repaired.
If the light stops flashing and remains on steady, see “If the Light Is On Steady” following. If the light continues to flash, when it is safe to do so, stop the vehicle. Find a safe place to park your vehicle. Turn the key off, wait at least 10 seconds and restart the engine. If the light remains on steady, see “If the Light Is On Steady” following. If the light is still flashing, follow the previous steps, and drive the vehicle to your dealer or qualified service center for service.
Emissions Inspection and Maintenance Programs Oil Pressure Gage Some state/provincial and local governments have or may begin programs to inspect the emission control equipment on your vehicle. Failure to pass this inspection could prevent you from getting a vehicle registration. Here are some things you need to know in order to help your vehicle pass an inspection: Your vehicle will not pass this inspection if the SERVICE ENGINE SOON or CHECK ENGINE light is on or not working properly.
Cruise Light (If Equipped) CAUTION: Don’t keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches fire. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced. United States NOTICE: Damage to your engine from neglected oil problems can be costly and is not covered by your warranty. Canada The CRUISE light comes on whenever you set your cruise control. See “Cruise Control” in the Index.
Here are some situations you may experience with your fuel gage. None of these indicate a problem with the fuel gage. Fuel Gage D At the gas station, the fuel pump shuts off before the gage reads F (Full). D It takes a little more or less fuel to fill up than the fuel gage indicated. For example, the gage may have indicated the tank was half full, but it actually took a little more or less than half the tank’s capacity to fill the tank. D The gage goes back to E (Empty) when you turn off the ignition.
BATTERY TRANS FLUID HOT If this message is displayed when the engine is running, you may have a problem with your charging system. If you have an automatic transmission, you have a transmission temperature warning display contained in the message center. If the transmission fluid temperature becomes high, the message center will display this message. The battery display will also stay on while the key is in RUN until the engine is started.
The following situations can cause the transmission to operate at higher temperatures: D D D D D D Towing a trailer TRANS HOT...IDLE ENGINE Your vehicle has a transmission over-temperature display contained in the message center. Hot outside air temperatures If this warning message is displayed, pull the vehicle off the roadway when it is safe to do so.

VENT: This setting directs the air through the instrument panel outlets. BI-LEVEL: Air is delivered through the heater floor outlets as well as the instrument panel outlets. The air flow can be divided between VENT and HEATER depending upon where the knob is placed between the settings. Fan Knob The knob on the left side of the control panel adjusts the fan speed.
Heater and Air Conditioning Comfort Controls (If Equipped) Mode Knob The right knob on the control panel allows you to choose the direction of air delivery. PANEL: This setting directs the air through the instrument panel outlets. Fan Knob The knob on the left side of the control panel adjusts the fan speed. To increase airflow, turn the knob clockwise. To decrease airflow, turn it counterclockwise. To turn the fan off, turn the knob to OFF.
DEFROST: This setting directs most of the air through the windshield defroster outlets, side window defroster outlets and some air through the heater outlets. When in the DEFROST mode, the air conditioning compressor may run to dehumidify the air to prevent window fogging. In the BLEND mode, outside air is forced to reduce window fogging. If the RECIRCULATION button is pressed, the LED indicator will flash three times indicating that forced outside air is activated and RECIRCULATION is not available.
Electronic Climate Control System (If Equipped) When both the Fan Control and Mode Knobs are in the AUTO position, the system will then automatically maintain the desired cabin temperature as selected by Temperature Knob. Manual control of functions is also available. Temperature Knob Fan Control The knob on the left side of the electronic climate control panel controls the fan speed. To manually increase airflow, move the knob clockwise. To manually decrease airflow, move it counterclockwise.
Mode Knob - Automatic Operation The right knob on the control panel allows you to choose the direction of air delivery. When the system is set for automatic operation, sensors will control the air delivery mode. Air will come primarily from the floor or instrument panel outlets, with some air directed to the windshield to prevent fogging. When the system is in AUTO mode, the air conditioning light will turn on, and the recirculation and outside air lights turn off.
Mode Knob - Manual Operation The right knob on the control panel allows you to choose the direction of air delivery. You can choose to set the climate control system operations yourself, or let the system work for you by placing the system in AUTO mode. See “Mode Knob - Automatic Operation” earlier in this section. PANEL: This setting directs most of the air through the instrument panel outlets and a small amount through the floor outlets.
Air conditioning will be automatically disabled when the outside temperature drops below a level which air conditioning is ineffective. To increase and decrease the flow of cooled air to the rear vents, turn the rotary knob to the blower speed you want. Remember that in order for the automatic system to perform well, it needs A/C to provide cooling performance. The knob has three speed positions. To increase the flow of cooled air, turn the switch toward 3.
Rear Air Conditioning and Rear Heater (If Equipped) If your vehicle has the rear air conditioning and rear heater system combination, controls are provided to regulate temperature, location and speed of the airflow. Generally, the upper vents are used for air conditioning and the floor vents for heating. The control knob can be set to any blend setting. To adjust the air temperature, turn the temperature knob on the center of the control panel.
Rear Air Conditioning and Heating Systems with Electronic Climate Control System (If Equipped) With this system the rear passengers can control the temperature of the air flow for his/her own zones. The climate control has three controls. To adjust the airflow speed, turn the fan control knob located on the left side of the control panel to the desired blower setting.
Air Conditioning On hot days, open the windows long enough to let hot air inside escape. This reduces the time it takes for your vehicle to cool down. Then keep your windows closed for the air conditioner to work its best. The RECIRCULATION button allows the air inside your vehicle to be recirculated. This setting helps to maximize your air conditioner’s performance and your vehicle’s fuel economy.
Heating Defogging and Defrosting The heater works best if you keep your windows closed while using it. On cold days, use the HEATER or VENT/HEAT setting with the temperature knob in the red area. On cool, humid days, use DEFOG to keep the windshield and side windows clear. Use DEFROST to remove fog or ice from the windshield in extremely humid or cold conditions. Use DEFROST with the temperature knob toward the red area and the fan control turned all the way to the right.
The defogger will shut itself off after several minutes. If you need additional warming time, press the button again. You can turn the defogger off at any time by pressing the button. If your vehicle is equipped with heated outside mirrors, the rear window defogger button will also activate the heated outside mirrors. Do not attach a temporary vehicle license, tape or decals across the defogger grid on the rear window.
Your vehicle has air outlets in the center and on the sides of the instrument panel and also may be equipped on the headliner. Ventilation Tips D Keep the hood and front air inlet free of ice, snow or any other obstruction (such as leaves). The heater and defroster will work far better, reducing the chance of fogging the inside of your windows. D When you enter a vehicle in cold weather, turn the blower fan all the way to the right for a few moments before driving.

Activating the Theft-Deterrent Feature The instructions which follow explain how to enter your secret code to activate the THEFTLOCK system. It is recommended that you read through all nine steps before starting the procedure. If you allow more than 15 seconds to elapse between any steps, the radio automatically reverts to time and you must start the procedure over at Step 4. 1. Write down any three or four-digit number from 000 to 1999 and keep it in a safe place separate from the vehicle. 2.
5. Press AM-FM after you have confirmed that the code matches the secret code you have written down. The display will show SEC, indicating the radio is now operable and secure. If you enter the wrong code eight times, INOP will appear on the display. You will have to wait an hour with the ignition on before you can try again. When you try again, you will only have three chances to enter the correct code before INOP appears. If you lose or forget your code, contact your dealer.
Understanding Radio Reception To help avoid hearing loss or damage: AM D Adjust the volume control to the lowest setting. D Increase volume slowly until you hear comfortably 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.
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. Cassette tapes should be stored in their cases away from contaminants, direct sunlight and extreme heat. If they aren’t, they may not operate properly or may cause failure of the tape player. Your tape player should be cleaned regularly after every 50 hours of use.
If your vehicle is equipped with the AM-FM Stereo with Cassette Tape Player: 1. Turn the ignition to RUN or ACCESSORY. 2. Turn the radio on. 3. Insert the scrubbing action cleaning cassette. 4. Within five seconds, press and hold the REV and FWD buttons at the same time for three seconds. The tape symbol on the display will flash, showing that the cut tape detection feature is no longer active. 5. Eject the cleaning cassette after the manufacturer’s recommended cleaning time.
Care of Your Compact Discs Fixed Mast Antenna Handle discs carefully. Store them in their original cases or other protective cases and away from direct sunlight and dust. If the surface of a disc is soiled, dampen a clean, soft cloth in a mild, neutral detergent solution and clean it, wiping from the center to the edge. The fixed mast antenna can withstand most car washes without being damaged. If the mast should ever become slightly bent, you can straighten it out by hand.
✍ 3-38 NOTES
Section 4 Your Driving and the Road Here you’ll find information about driving on different kinds of roads and in varying weather conditions. We’ve also included many other useful tips on driving.
Defensive driving really means “be ready for anything.” On city streets, rural roads or freeways, it means “always expect the unexpected.” Assume that pedestrians or other drivers are going to be careless and make mistakes. Anticipate what they might do. Be ready for their mistakes. Rear-end collisions are about the most preventable of accidents. Yet they are common. Allow enough following distance. It’s the best defensive driving maneuver, in both city and rural 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: D D D D Judgment Muscular Coordination Vision Attentiveness. Police records show that almost half of all motor vehicle-related deaths involve alcohol. In most cases, these deaths are the result of someone who was drinking and driving.
Since alcohol is carried in body water, this means that a woman generally will reach a higher BAC level than a man of her same body weight when each has the same number of drinks. The law in many U.S. states sets the legal limit at a BAC of 0.10 percent. In a growing number of U.S. states, and throughout Canada, the limit is 0.08 percent. In some other countries, it’s even lower. The BAC limit for all commercial drivers in the United States is 0.04 percent. The BAC will be over 0.
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. There’s something else about drinking and driving that many people don’t know.
Control of a Vehicle Braking 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. Braking action involves perception time and reaction time. First, you have to decide to push on the brake pedal. That’s perception time. Then you have to bring up your foot and do it. That’s reaction time. Average reaction time is about 3/4 of a second.
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. If you keep pace with the traffic and allow realistic following distances, you will eliminate a lot of unnecessary braking. That means better braking and longer brake life.
The anti-lock system can change the brake pressure faster than any driver could. The computer is programmed to make the most of available tire and road conditions. 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. You can steer around the obstacle while braking hard. A computer senses that wheels are slowing down.
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. Always leave enough room up ahead to stop, even though you have anti-lock brakes. Using Anti-Lock Don’t pump the brakes. Just hold the brake pedal down firmly and let anti-lock work for you.
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 turn the cruise control back on. See “Cruise Control” in the Index. When the TRACTION OFF light is on, the TAS is off and will not limit wheel spin. Adjust your driving accordingly.
If desired, you can change the TAS automatic engagement feature so that the system will not come on automatically when the engine is started. To do so: Steering 1. Park vehicle with ignition off and transmission in PARK (P). If you lose power steering assist because the engine stops or the system is not functioning, you can steer but it will take much more effort. 2. Turn the ignition to RUN; do not start the engine. Power Steering 3.
Suppose you’re steering through a sharp curve. Then you suddenly accelerate. Both control systems -- steering and acceleration -- have to do their work where the tires meet the road. Adding the sudden acceleration can demand too much of those places. You can lose control. Refer to “Traction Assist System” in the Index. 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.
Off-Road Recovery You may find that your right wheels have dropped off the edge of a road onto the shoulder while you’re driving. 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.
Passing The driver of a vehicle about to pass another on a two-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-lane highway is a potentially dangerous move, since the passing vehicle occupies the same lane as oncoming traffic for several seconds.
D 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. (Remember that if your right outside mirror is convex, the vehicle you just passed may seem to be farther away from you than it really is.) D Try not to pass more than one vehicle at a time on two-lane roads.
A cornering skid is best handled by easing your foot off the accelerator pedal. If you have the “Traction Assist System,” remember: It helps avoid only the acceleration skid. If you do not have this system, or if the system is off, then an acceleration skid is also best handled by easing your foot off the accelerator pedal. If your vehicle starts to slide, ease your foot off the accelerator pedal and quickly steer the way you want the vehicle to go.
Off-road driving involves some new skills. And that’s why it’s very important that you read this guide. You’ll find many driving tips and suggestions. These will help make your off-road driving safer and more enjoyable. If you think you will need some more ground clearance at the front of your vehicle, you can easily remove the front bumper lower air dam. The front bumper lower air dam is held in place by a series of push pins located around the lower edge of the front bumper.
3. Pull the push-pins and lower air dam assembly away from the retainers until the lower air dam is free. To replace the lower air dam: 1. Line up each push-pin with its intended retainer and push the washer portion of the push-pin towards the retainer until it locks into place When you’re back on roads, though, be sure to replace the air dam.
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.
Environmental Concerns Off-road driving can provide wholesome and satisfying recreation. However, it also raises environmental concerns. GM recognizes these concerns and urges every off-roader to follow these basic rules for protecting the environment: D Always use established trails, roads and areas that have been specially set aside for public off-road recreational driving; obey all posted regulations.
Controlling your vehicle is the key to successful off-road driving. One of the best ways to control your vehicle is to control your speed. Here are some things to keep in mind. At higher speeds: D you approach things faster and you have less time to scan the terrain for obstacles. D you have less time to react. D you have more vehicle bounce when you drive over obstacles. D you’ll need more distance for braking, especially since you’re on an unpaved surface.
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. If this happens, even with one or two wheels, you can’t control the vehicle as well or at all. Because you will be on an unpaved surface, it’s especially important to avoid sudden acceleration, sudden turns or sudden braking.
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. Driving Uphill Here are some other things to consider as you approach a hill.
D Ease up on your speed as you approach the top Q: What should I do if my vehicle stalls, or is about to stall, and I can’t make it up the hill? D Attach a flag to the vehicle to make you more visible A: If this happens, there are some things you should do, and there are some things you must not do. First, here’s what you should do: of the hill. to approaching traffic on trails or hills. D Sound the horn as you approach the top of the hill to let opposing traffic know you’re there.
Here are some things you must not do if you stall, or are about to stall, when going up a hill. D 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. Instead, apply the regular brake to stop the vehicle. Then apply the parking brake. Shift to REVERSE (R), release the parking brake, and slowly back straight down.
Driving Downhill When off-roading takes you downhill, you’ll want to Q: Are there some things I should not do when driving down a hill? consider a number of things: D How steep is the downhill? Will I be able to maintain vehicle control? D What’s the surface like? Smooth? Rough? Slippery? Hard-packed dirt? Gravel? D Are there hidden surface obstacles? Ruts? Logs? Boulders? D What’s at the bottom of the hill? Is there a hidden creek bank or even a river bottom with large rocks? If you decide you can go do
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: D A hill that can be driven straight up or down may be too steep to drive across. When you go straight up or down a hill, the length of the wheel base (the distance from the front wheels to the rear wheels) reduces the likelihood the vehicle will tumble end over end.
Q: What if I’m driving across an incline that’s not too steep, but I hit some loose gravel and start to slide downhill. What should I do? A: If you feel your vehicle starting to slide sideways, turn downhill. This should help straighten out the vehicle and prevent the side slipping. However, a much better way to prevent this is to get out and “walk the course” so you know what the surface is like before you drive it.
Driving in Mud, Sand, Snow or Ice When you drive in mud, snow or sand, your wheels won’t get good traction. You can’t accelerate as quickly, turning is more difficult, and you’ll need longer braking distances. It’s best to use a low gear when you’re in mud -- the deeper the mud, the lower the gear. In really deep mud, the idea is to keep your vehicle moving so you don’t get stuck. When you drive on sand, you’ll sense a change in wheel traction. But it will depend upon how loosely packed the sand is.
If the water isn’t too deep, then drive through it slowly. At fast speeds, water splashes on your ignition system and your vehicle can stall. Stalling can also occur if you get your tailpipe under water. And, as long as your tailpipe is under water, you’ll never be able to start your engine. When you go through water, remember that when your brakes get wet, it may take you longer to stop. CAUTION: Driving through rushing water can be dangerous.
Driving at Night Here are some tips on night driving. D Drive defensively. D Don’t drink and drive. D Adjust your inside rearview mirror to reduce the D D D D Night driving is more dangerous than day driving. One reason is that some drivers are likely to be impaired -- by alcohol or drugs, with night vision problems, or by fatigue. glare from headlamps behind you. Since you can’t see as well, you may need to slow down and keep more space between you and other vehicles.
You can be temporarily blinded by approaching headlamps. It can take a second or two, or even several seconds, for your eyes to readjust to the dark. When you are faced with severe glare (as from a driver who doesn’t lower the high beams, or a vehicle with misaimed headlamps), slow down a little. Avoid staring directly into the approaching headlamps. Driving in Rain and on Wet Roads Keep your windshield and all the glass on your vehicle clean -- inside and out.
The heavier the rain, the harder it is to see. Even if your windshield wiper blades are in good shape, a heavy rain can make it harder to see road signs and traffic signals, pavement markings, the edge of the road and even people walking. It’s wise to keep your wiping equipment in good shape and keep your windshield washer tank filled with washer fluid.
Hydroplaning doesn’t happen often. But it can if your tires do not have much tread or if the pressure in one or more is low. It can happen if a lot of water is standing on the road. If you can see reflections from trees, telephone poles or other vehicles, and raindrops “dimple” the water’s surface, there could be hydroplaning. Driving Through Flowing Water CAUTION: Flowing or rushing water creates strong forces.
City Driving Here are ways to increase your safety in city driving: D Know the best way to get to where you are going. Get a city map and plan your trip into an unknown part of the city just as you would for a cross-country trip. D Try to use the freeways that rim and crisscross most large cities. You’ll save time and energy. (See the next part, “Freeway Driving.”) D Treat a green light as a warning signal. A traffic light is there because the corner is busy enough to need it.
Freeway Driving 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. Too-fast or too-slow driving breaks a smooth traffic flow. Treat the left lane on a freeway as a passing lane. At the entrance, there is usually a ramp that leads to the freeway. If you have a clear view of the freeway as you drive along the entrance ramp, you should begin to check traffic.
Once you are moving on the freeway, make certain you allow a reasonable following distance. Expect to move slightly slower at night. When you want to leave the freeway, move to the proper lane well in advance. If you miss your exit, do not, under any circumstances, stop and back up. Drive on to the next exit. The exit ramp can be curved, sometimes quite sharply. The exit speed is usually posted. Reduce your speed according to your speedometer, not to your sense of motion.
Highway Hypnosis Hill and Mountain Roads 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.
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-Road Driving” in the Index for information about driving off-road.) 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 wouldn’t work well. You would then have poor braking or even none going down a hill. You could crash.
Winter Driving 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. And, if you will be driving under severe conditions, include a small bag of sand, a piece of old carpet or a couple of burlap bags to help provide traction. Be sure you properly secure these items in your vehicle.
Whatever the condition -- smooth ice, packed, blowing or loose snow -- drive with caution. Accelerate gently. Try not to break the fragile traction. If you accelerate too fast, the drive wheels will spin and polish the surface under the tires even more. Your anti-lock brakes improve your vehicle’s stability when you make a hard stop on a slippery road. Even though you have an anti-lock braking system, you’ll want to begin stopping sooner than you would on dry pavement. See “Anti-Lock” in the Index.
If You’re Caught in a Blizzard D Tie a red cloth to your vehicle to alert police that you’ve been stopped by the snow. D Put on extra clothing or wrap a blanket around you. If you have no blankets or extra clothing, make body insulators from newspapers, burlap bags, rags, floor mats -- anything you can wrap around yourself or tuck under your clothing to keep warm. If you are stopped by heavy snow, you could be in a serious situation.
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. And check around again from time to time to be sure snow doesn’t collect there. Open a window just a little on the side of the vehicle that’s away from the wind.
Recreational Vehicle Towing There may be times when you want to tow your vehicle behind another vehicle for use at your destination. Be sure to use the proper towing equipment designed for recreational vehicle towing. Follow the instructions for the towing equipment. When towing your vehicle, turn the ignition to OFF. To prevent your battery from draining while towing, remove the IGN 0 fuse from the instrument panel fuse block. Be sure to replace the fuse when you reach your destination.
Four-Wheel-Drive Vehicles D Securely attach the vehicle being towed to the tow vehicle. CAUTION: Shifting the transfer case into NEUTRAL (N) can cause your vehicle to roll even if the transmission is in PARK (P), for an automatic transmission. You or others could be injured. Make sure the parking brake is firmly set before you shift the transfer case into NEUTRAL (N). D Firmly set the parking brake. D Shift the transmission to PARK (P). D Shift the transfer case to NEUTRAL (N).
Loading Your Vehicle 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 GVWR (Gross Vehicle Weight Rating). The GVWR includes the weight of the vehicle, all occupants, fuel and cargo. The Certification/Tire label also tells you the maximum weights for the front and rear axles, called Gross Axle Weight Rating (GAWR).
NOTICE: Some vehicles may be equipped with RPO VYU (snow plow prep package). With this option, the payload your vehicle can carry is reduced when a snow plow is installed. Your vehicle can be damaged if either the front or rear axle ratings, or the GVW are exceeded. As a general guideline, with a 650 lb. (295 kg) snow plow, the weight of the occupants and cargo must not exceed 300 lb. (135 kg). However, this may depend on the vehicle’s option content.
Your warranty does not cover parts or components that fail because of overloading. The label will help you decide how much cargo and installed equipment your truck can carry. Using heavier suspension components to get added durability might not change your weight ratings. Ask your dealer to help you load your vehicle the right way. If you put things inside your vehicle -- like suitcases, tools, packages, or anything else -- they go as fast as the vehicle goes.
Front Axle Reserve Capacity This is the difference between your front GAWR and the front axle weight of your truck with full fuel and passengers. It is the amount of weight you can add to your front axle before reaching your front GAWR. The front axle reserve capacity for your vehicle can be found in the lower right hand corner of the tire/certification label, as shown in this example. (W x (A+W.B.)) / W.B.
For example, adding a 700 lb. ( 318 kg) snow plow adds more than 700 lb. ( 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) and W.B.= 10 ft. (305 cm) (W x (A+W.B.)) / W.B. = (700 x (4ft. + 10 ft.)) / 10 ft. = 980 lbs. So, if your truck’s front axle reserve capacity is more than 980 lbs. (445 kg), you could add this snow plow without exceeding the front GAWR.
Towing a Trailer CAUTION: If you don’t use the correct equipment and drive properly, you can lose control when you pull a trailer. For example, if the trailer is too heavy, the brakes may not work well -- or even at all. You and your passengers could be seriously injured. Pull a trailer only if you have followed all the steps in this section. Ask your dealer for advice and information about towing a trailer with your vehicle.
If You Do Decide To Pull A Trailer If you do, here are some important points: D There are many different laws, including speed limit restrictions, having to do with trailering. Make sure your rig will be legal, not only where you live but also where you’ll be driving. A good source for this information can be state or provincial police. D Consider using a sway control if your trailer will weigh less than the capacity stamped on your step bumper.
Your vehicle is equipped with a button at the end of the shift lever which, when pressed, enables tow/haul. Your vehicle may be equipped with Autoridet which further improves your vehicle’s ride while towing. See “Autoridet” in the Index for more information. When the button is pressed, a light on the instrument panel will illuminate to indicate that tow/haul has been selected. Tow/haul may be turned off by pressing the button again, at which time the indicator light on the instrument panel will turn off.

Weight of the Trailer Tongue The tongue load (A) of any trailer is an important weight to measure because it affects the total or gross weight of your vehicle. The Gross Vehicle Weight (GVW) includes the curb weight of the vehicle, any cargo you may carry in it, and the people who will be riding in the vehicle. And if you will tow a trailer, you must add the tongue load to the GVW because your vehicle will be carrying that weight, too.
Hitches Safety Chains It’s important to have the correct hitch equipment. Crosswinds, large trucks going by and rough roads are a few reasons why you’ll need the right hitch. Here are some rules to follow: 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.
Trailer Brakes If your trailer weighs more than 2,000 lbs. (900 kg) loaded, then it needs its own brakes -- and they must be adequate. Be sure to read and follow the instructions for the trailer brakes so you’ll be able to install, adjust and maintain them properly. Your trailer brake system can tap into the vehicle’s hydraulic brake system only if: D The trailer parts can withstand 3,000 psi (20 650 kPa) of pressure. D The trailer’s brake system will use less than 0.02 cubic inches (0.
Towing a trailer requires a certain amount of experience. Before setting out for the open road, you’ll want to get to know your rig. Acquaint yourself with the feel of handling and braking with the added weight of the trailer. And always keep in mind that the vehicle you are driving is now a good deal longer and not nearly as responsive as your vehicle is by itself.
Making Turns NOTICE: Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. Your vehicle could be damaged. Avoid making very sharp turns while trailering. When you’re turning with a trailer, make wider turns than normal. Do this so your trailer won’t strike soft shoulders, curbs, road signs, trees or other objects. Avoid jerky or sudden maneuvers. Signal well in advance.
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. But if you ever have to park your rig on a hill, here’s how to do it: 1. Apply your regular brake, but don’t shift into PARK (P) yet. 2. Have someone place chocks under the trailer wheels. 3.
When You Are Ready to Leave After Parking on a Hill 1. Apply your regular brakes and hold the pedal down while you: D Start your engine; D Shift into a gear; and D Release the parking brake. Trailer Wiring Harness Your vehicle is equipped with the following wiring harnesses for towing a trailer. Basic Trailer Wiring Package 2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear of the chocks. 4. Stop and have someone pick up and store the chocks.

Power Winches Step-Bumper Pad If you wish to use a power winch on your vehicle, only use it when your vehicle is stationary or anchored. If your vehicle has a rear step bumper, it may be equipped with a rear step pad at the center of the bumper. NOTICE: Using a power winch with the transmission in gear may damage the transmission. When operating a power winch, always leave the transmission in NEUTRAL (N).
✍ 4-66 NOTES
Section 5 Problems on the Road Here you’ll find what to do about some problems that can occur on the road.
Hazard Warning Flashers Press the button at the top of the steering column all the way down to make your front and rear turn signal lamps flash on and off. Your hazard warning flashers work no matter what position your key is in, and even if the key isn’t in. To turn off the flashers, press the button until the first click and release. Your hazard warning flashers let you warn others. They also let police know you have a problem. Your front and rear turn signal lamps will flash on and off.
Jump Starting If your battery has run down, you may want to use another vehicle and some jumper cables to start your vehicle. But please use the following steps to do it safely. CAUTION: Batteries can hurt you. They can be dangerous because: D They contain acid that can burn you. D They contain gas that can explode or ignite. D They contain enough electricity to burn you. If you don’t follow these steps exactly, some or all of these things can hurt you.
1. Check the other vehicle. It must have a 12-volt battery with a negative ground system. NOTICE: If the other system isn’t a 12-volt system with a negative ground, both vehicles can be damaged. 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.
4. Open the hoods and locate the positive (+) and negative (-) terminal locations on the other vehicle. Your vehicle has a remote positive (+) jump starting terminal and a remote negative (-) jump starting terminal. The remote positive (+) terminal is located behind a red plastic cover near the driver’s side of the engine accessory drive bracket. To uncover the remote positive (+) terminal, open the red plastic cover. The remote negative (-) terminal is located on the engine accessory drive bracket.
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 (+) or a remote positive terminal if the vehicle has one. Negative (-) will go to a heavy-unpainted metal engine part or a remote negative terminal if the vehicle has one.
8. Now connect the black negative (-) cable to the good battery’s negative (-) cable. Use a remote negative (-) terminal if the vehicle has one. 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 of the vehicle with the dead battery or to a remote negative (-) terminal if the vehicle has one. 9. When connecting the cable, be sure it is not near any engine parts that will move. 10.
12. Remove the cables in reverse order to prevent electrical shorting. Take care that they don’t touch each other or any other metal. Towing Your Vehicle CAUTION: To help avoid serious personal injury to you or others: D Never let passengers ride in a vehicle that is being towed. D Never tow faster than safe or posted speeds. D Never tow with damaged parts not fully secured. D Never get under your vehicle after it has been lifted by the tow truck.
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 wheel-lift equipment or car carrier equipment. Two-Wheel-Drive vehicle towing limits for wheel lift equipment are as follows: D Front Towing -- 35 mph (55 km/h) for 50 miles (80 km) D Rear Towing -- 55 mph (88 km/h) or legal speed limit and the distance is unlimited. Four-Wheel-Drive vehicles must have the transfer case in NEUTRAL (N).
NOTICE: After driving in the overheated engine protection operating mode, to avoid engine damage, allow the engine to cool before attempting any repair. The engine oil will be severely degraded. Repair the cause of coolant loss, change the oil and reset the oil life monitor. See “Engine Oil” in the Index. If Steam Is Coming From Your Engine 5-10 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.
NOTICE: If your engine catches fire because you keep driving with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by your warranty. See “Overheated Engine Protection Operating Mode” in the Index. 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: D D D D Climb a long hill on a hot day. Stop after high-speed driving.
Cooling System When you decide it’s safe to lift the hood, here’s what you’ll see: CAUTION: If your vehicle has air conditioning, the auxiliary electric engine cooling fan under the hood can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan. If the coolant inside the coolant recovery tank surge tank tank is boiling, don’t do anything else until it cools down.
If it isn’t, you may have a leak in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system. CAUTION: Heater and radiator hoses, and other engine parts, can be very hot. 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. Get any leak fixed before you drive the vehicle.
How to Add Coolant to the Coolant Surge Tank If you haven’t found a problem yet, but the coolant level isn’t at or above the FILL COLD mark, add a 50/50 mixture of clean, drinkable water and DEX-COOLR coolant at the coolant surge tank, but be sure the cooling system, including the coolant surge tank pressure cap, is cool before you do it. (See “Engine Coolant” in the Index for more information.) CAUTION: Steam and scalding liquids from a hot cooling system can blow out and burn you badly.
CAUTION: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid like 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 wouldn’t get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX-COOLR coolant.
1. You can remove the coolant surge tank pressure cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise (left) about one full turn. If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left. 2. Then keep turning the pressure cap slowly, and remove it. 5-16 3. Then fill the coolant surge tank with the proper mixture, to the FILL 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. Watch out for the engine cooling fan. 5. Then replace the pressure cap. Be sure the pressure cap is hand-tight. By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mixture to the coolant surge tank until the level reaches the FILL COLD mark.
Engine Fan Noise If a Tire Goes Flat 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. Under heavy vehicle loading, trailer towing and/or high outside temperatures, the fan speed increases as the clutch more fully engages. So you may hear an increase in fan noise.
Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning flashers. CAUTION: Changing a tire can cause an injury. The vehicle can slip off the jack and roll over you or other people. You and they could be badly injured. Find a level place to change your tire. To help prevent the vehicle from moving: 1. Set the parking brake firmly. 2.
Removing the Spare Tire and Tools The equipment you’ll need is under the storage tray in the left trim panel for Suburban/Yukon XL Models. For Utility Models, the equipment is located under the rear seat behind the driver’s seat and behind the left trim panel in the rear of the vehicle. Skip the first step and follow the last three. 1. Remove the tray to access the tools. 2. There is a wing nut used to retain the tool kit. To remove it, turn the wing nut counterclockwise. 3.
Follow these instructions to lower the spare tire: 1. If the vehicle is equipped with a hoist lock, open the spare tire lock cover on the bumper and use the ignition key to remove the lock. 2. Assemble the wheel wrench and the two jack handle extensions as shown. Insert the hoist end (open end) of the extension through the hole in the rear bumper. Be sure the hoist end of the extension connects into the hoist shaft (the ribbed square end of the extension is used to lower the spare tire). 3.
Attach the wheel wrench to the jack handle extensions (as needed). Attach the jack handle to the jack. 5-22 Turn the wheel wrench clockwise to raise the jack lift head to the lifting point.
If your vehicle has wheel nut caps, loosen them by turning the wheel wrench counterclockwise. If you have a center cap with wheel nut caps, the wheel nut caps are designed to remain with the center cap. Remove the center cap. Removing the Flat Tire and Installing the Spare Tire 1. Use the wheel wrench to loosen all the wheel nuts. Turn the wheel wrench counterclockwise to loosen the wheel nuts. Don’t remove the wheel nuts yet.
CAUTION: Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack, you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack. Position the jack under the vehicle. If the flat tire is on the front of the vehicle, position the jack on the frame behind the flat tire where the frame sections overlap. On all 1500 Series vehicles, use the jacking pad provided on the rear axle.
Rear Position 1500 Series Rear Position 2500 Series Front Position 2. Make sure the jack head is positioned so that the rear axle is resting securely between the grooves that are on the jack head. Turn the wheel wrench clockwise to raise the vehicle. Raise the vehicle far enough off the ground so there is enough room for the spare tire to fit back underneath the rear of the vehicle.
3. Remove all the wheel nuts and take off the flat tire. 4. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel. CAUTION: Rust or dirt on the wheel, or on the parts to which it is fastened, can make the 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 the places where the wheel attaches to the vehicle.
5. After mounting the spare, replace the wheel nuts with the rounded end of the nuts toward the wheel. Tighten each wheel nut by hand using the wheel wrench until the wheel is held against the hub. Rear Position 1500 Series Rear Position 2500 Series 6. Turn the wheel wrench counterclockwise to lower the vehicle. Lower the jack completely.
CAUTION: 7. Tighten the nuts firmly in a crisscross sequence as shown by turning the wheel wrench clockwise. Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to become loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque.
Storing a Flat or Spare Tire and Tools CAUTION: Storing a jack, a tire or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place. 4. Raise the tire part way upward. Make sure the retainer is seated in the wheel opening. 5. Raise the tire fully against the underside of the vehicle. Continue turning the wheel wrench until the tire is secure and the cable is tight.
Replace the jack, tools and spare tire lock. For Utility Models: 1. Put the tool kit with the jack tools and gloves in the tool bag and place in the retaining dip under the driver’s side second seat. 2. Tighten down with the the wing nut. 3. Then, assemble wheel chocks and bottle jack together with the wing nut and retaining hook. 4. Position behind the jack storage cover in the left rear side panel just below the speaker and tighten, adjusting clockwise until the jack is secured tight in mounting bracket.
If You’re Stuck: In Sand, Mud, Ice or Snow NOTICE: In order to free your vehicle when it is stuck, you will need to spin the wheels, but you don’t want to spin your wheels too fast. The method known as “rocking” can help you get out when you’re stuck, but you must use caution. Spinning your wheels can destroy parts of your vehicle as well as the tires. If you spin the wheels too fast while shifting your transmission back and forth, you can destroy your transmission.
Rocking Your Vehicle To Get It Out Using the Recovery Hooks First, turn your steering wheel left and right. That will clear the area around your front wheels. If you have a four-wheel drive vehicle, shift into 4HI or 4LO. If your vehicle has the Traction Assist System, you should turn it off by pressing the TAS on/off button. Then shift back and forth between REVERSE (R) and a forward gear, spinning the wheels as little as possible.
CAUTION: The recovery 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. NOTICE: Never use the recovery hooks to tow the vehicle. Your vehicle could be damaged and it would not be covered by warranty.
✍ 5-34 NOTES
Section 6 Service and Appearance Care Here you will find information about the care of your vehicle. This section begins with service and fuel information, and then it shows how to check important fluid and lubricant levels. There is also technical information about your vehicle, and a part devoted to its appearance care.
Service Doing Your Own Service Work Your dealer knows your vehicle best and wants you to be happy with it. We hope you’ll go to your dealer for all your service needs. You’ll get genuine GM parts and GM-trained and supported service people. If you want to do some of your own service work, you’ll want to use the proper service manual. It tells you much more about how to service your vehicle than this manual can. To order the proper service manual, see “Service and Owner Publications” in the Index.
CAUTION: You can be injured and your vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it. D Be sure you have sufficient knowledge, experience, the proper replacement parts and tools before you attempt any vehicle maintenance task. D Be sure to use the proper nuts, bolts and other fasteners. “English” and “metric” fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt.
If your vehicle is certified to meet California Emission Standards (indicated on the underhood emission control label), it is designed to operate on fuels that meet California specifications. If such fuels are not available in states adopting California emissions standards, your vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected.
Fuels in Foreign Countries If you plan on driving in another country outside the United States or Canada, the proper fuel may be hard to find. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel wouldn’t be covered by your warranty. To check on fuel availability, ask an auto club, or contact a major oil company that does business in the country where you’ll be driving.
CAUTION: If you get gasoline on yourself and then something ignites it, you could be badly burned. Gasoline can spray out on you if you open the fuel filler cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel filler cap slowly and wait for any “hiss” noise to stop. Then unscrew the cap all the way. While refueling, hang the filler cap by the tether using the hook located on the inside of the filler door.
When you put the cap back on, turn it to the right (clockwise) until you hear a clicking sound. Make sure you fully install the cap. The diagnostic system can determine if the fuel cap has been left off or improperly installed. This would allow fuel to evaporate into the atmosphere. See “Malfunction Indicator Lamp” in the Index. NOTICE: If you need a new cap, be sure to get the right type. Your dealer can get one for you. If you get the wrong type, it may not fit properly.
Checking Things Under the Hood CAUTION: Things that burn can get on hot engine parts and start a fire. These include liquids like fuel, oil, coolant, brake fluid, windshield washer and other fluids, and plastic or rubber. You or others could be burned. Be careful not to drop or spill things that will burn onto a hot engine. Hood Release To open the hood, first pull the handle inside the vehicle located under and to the left of the steering wheel.

Engine Oil If the CHECK ENG OIL LEVEL appears on the instrument panel, it means you need to check your engine oil level right away. The engine oil dipstick has a yellow ring handle and is located on the passenger’s side of the engine. For more information, see CHECK ENG OIL LEVEL in the Index. You should check your engine oil level regularly; this is an added reminder. Checking Engine Oil Turn off the engine and give the oil several minutes to drain back into the oil pan.
NOTICE: Don’t add too much oil. If your engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, your engine could be damaged. When to Add Engine Oil If the oil is at or below the ADD mark, then you’ll need to add at least one quart of oil. But you must use the right kind. This part explains what kind of oil to use. For crankcase capacity, see “Capacities and Specifications” in the Index.
What Kind of Engine Oil to Use Oils recommended for your vehicle can be identified by looking for the starburst symbol. This symbol indicates that the oil has been certified by the American Petroleum Institute (API). Do not use any oil which does not carry this starburst symbol. If you change your own oil, be sure you use oil that has the starburst symbol on the front of the oil container.
As shown in the chart, SAE 5W-30 is best for your vehicle. However, you can use SAE 10W-30 if it’s going to be 0 F (-18 C) or above. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils, such as SAE 20W-50. _ _ Engine Oil Additives Don’t add anything to your oil. The recommended oils with the starburst symbol are all you will need for good performance and engine protection.
How to Reset the CHANGE ENGINE OIL Message To reset the CHANGE ENGINE OIL message, turn the ignition key to RUN with the engine off. Fully press and release the accelerator pedal three times within five seconds. If the CHANGE ENGINE OIL message flashes for five seconds, the system is reset. What to Do with Used Oil Did you know that used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer? Don’t let used oil stay on your skin for very long.
Your air cleaner is located in the passenger’s side front corner of the engine compartment. 1. To remove the air filter, loosen the screws on the cover. Then lift the cover upward and remove the filter out of the air cleaner housing. Care should be taken to dislodge as little dirt as possible. 2. Clean the filter sealing surface and the filter housing. 3. Install the new filter. 4. Install the cover and tighten the screws on the air cleaner cover.
CAUTION: Operating the engine with the air cleaner/filter off can cause you or others to be burned. The air cleaner not only cleans the air, it stops flame if the engine backfires. If it isn’t there, and the engine backfires, you could be burned. Don’t drive with it off, and be careful working on the engine with the air cleaner/filter off. NOTICE: If the air cleaner/filter is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it.
3. Remove the air filter by pulling downward on the element. Remove the second portion of the air filter by sliding it towards the rear of the vehicle and then pulling downward. 4. Install the new filter by reversing the steps listed previously. Be sure to follow any instructions that may be included in the replacement filter package. Refer to the Maintenance Schedule to determine when to replace the passenger compartment air filter. See “Scheduled Maintenance” in the Index.
Wait at least 30 minutes before checking the transmission fluid level if you have been driving: D D D D When outside temperatures are above 90_F (32_C). At high speed for quite a while. In heavy traffic -- especially in hot weather. While pulling a trailer. To get the right reading, the fluid should be at normal operating temperature, which is 180_F to 200_F (82_C to 93_C). Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above 50_F (10_C).
Then, without shutting off the engine, follow these steps: 3. Check both sides of the dipstick, and read the lower level. The fluid level must be in the COLD area, below the cross-hatched area, for a cold check or in the HOT area or cross-hatched area for a hot check. 1. The red transmission dipstick handle is located at the rear of the engine compartment, on the passenger’s side. Flip the handle up and then pull out the dipstick and wipe it with a clean rag or paper towel. 4.
How to Add Fluid Rear Axle Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See “Recommended Fluids and Lubricants” in the Index. When to Check Lubricant Add fluid only after checking the transmission fluid while it is hot. (A cold check is used only as a reference.) If the fluid level is low, add only enough of the proper fluid to bring the level up to the HOT area for a hot check. It doesn’t take much fluid, generally less than one pint (0.5 L). Don’t overfill.
The proper level for the 1500 Series is from 5/8 inch to 1 5/8 inch (15 mm to 40 mm) below the filler plug. The proper level for the 2500 Series is from 0 to 3/8 inch (0 to 10 mm) below the filler plug. Add only enough fluid to reach the proper level. How to Check Lubricant What to Use Refer to the Maintenance Schedule to determine what kind of lubricant to use. See “Recommended Fluids and Lubricants” in the Index.
When to Check Lubricant When the differential is cold, add enough lubricant to raise the level to 1/2 inch (12 mm) below the filler plug hole. Refer to the Maintenance Schedule to determine how often to check the lubricant. See “Scheduled Maintenance Services” in the Index. When the differential is at operating temperature (warm), add enough lubricant to raise the level to the bottom of the filler plug hole.
A 50/50 mixture of clean, drinkable water and DEX-COOLR coolant will: D D D D D Give freezing protection down to -34_F (-37_C). Give boiling protection up to 265_F (129_C). Protect against rust and corrosion. Help keep the proper engine temperature. Let the warning lights and gages work as they should. NOTICE: When adding coolant, it is important that you use only DEX-COOLR (silicate-free) coolant.
NOTICE: Checking Coolant The coolant surge tank is located on the passenger’s side of the engine compartment. If you use an improper coolant mixture, your engine could overheat and be badly damaged. The repair cost wouldn’t be covered by your warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core and other parts. If you have to add coolant more than four times a year, have your dealer check your cooling system.
If the LOW COOLANT comes on and stays on, it means you’re low on engine coolant. Coolant Surge Tank Pressure Cap See “Low Coolant” in the Index. Adding Coolant If you need more coolant, add the proper DEX-COOLR coolant mixture at the surge tank, but only when the engine is cool. 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.
Power Steering Fluid How to Check Power Steering Fluid Turn the key off, let the engine compartment cool down, wipe the cap and the top of the reservoir clean, then unscrew the cap and wipe the dipstick with a clean rag. Replace the cap and completely tighten it. Then remove the cap again and look at the fluid level on the dipstick. The level should be at the FULL COLD mark. If necessary, add only enough fluid to bring the level up to the mark.
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. NOTICE: D When using concentrated washer fluid, D Adding Washer Fluid D D follow the manufacturer’s instructions for adding water. Don’t mix water with ready-to-use washer fluid.
Brakes Brake Fluid Your brake master cylinder reservoir is filled with DOT-3 brake fluid. So, it isn’t a good idea to “top off” your brake fluid. Adding brake fluid won’t correct a leak. If you add fluid when your linings are worn, then you’ll have too much fluid when you get new brake linings. You should add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system. CAUTION: There are only two reasons why the brake fluid level in the reservoir might go down.
Checking Brake Fluid What to Add When you do need brake fluid, use only DOT-3 brake fluid. Refer to “Recommended Fluids and Lubricants” in the Index. Use new brake fluid from a sealed container only. Always clean the brake fluid reservoir cap and the area around the cap before removing it. This will help keep dirt from entering the reservoir. CAUTION: You can check the brake fluid without taking off the cap.
NOTICE: D Using the wrong fluid can badly damage D 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. Don’t let someone put in the wrong kind of fluid. If you spill brake fluid on your vehicle’s painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately. See “Appearance Care” in the Index.
NOTICE: Continuing to drive with worn-out brake pads could result in costly brake repair. Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes. 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.
Battery Your new vehicle comes with a maintenance free ACDelcoR battery. When it’s time for a new battery, get one that has the replacement number shown on the original battery’s label. We recommend an ACDelco battery. Vehicle Storage If you’re not going to drive your vehicle for 25 days or more, remove the black, negative (-) cable from the battery. This will help keep your battery from running down. CAUTION: Batteries have acid that can burn you and gas that can explode.

Windshield Wiper Blade Replacement Replacement blades come in different types and are removed in different ways. For proper type and length, see “Normal Maintenance Replacement Parts” in the Index. Here’s how to remove the Shephard’s Hook type. To replace the windshield wiper blade assembly: 1. Lift the wiper arm and rotate the blade until it is facing away from the windshield. 2. Push the release lever and slide the wiper assembly toward the driver’s side of the vehicle. 3.
Inflation -- Tire Pressure CAUTION: Poorly maintained and improperly used tires are dangerous. D Overloading your tires can cause overheating as a result of too much friction. You could have an air-out and a serious accident. See “Loading Your Vehicle” in the Index. D Underinflated tires pose the same danger as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your tires are cold.
When to Check NOTICE: Don’t let anyone tell you that underinflation or overinflation is all right. It’s not. If your tires don’t have enough air (underinflation), you can get the following: D Too much flexing D Too much heat D Tire overloading D Bad wear D Bad handling D Bad fuel economy. If your tires have too much air (overinflation), you can get the following: D Unusual wear D Bad handling D Rough ride D Needless damage from road hazards. 6-38 Check your tires once a month or more.
The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See “Scheduled Maintenance Services” in the Index for scheduled rotation intervals. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Certification/Tire label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” in the Index.
When It’s Time for New Tires One way to tell when it’s time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining. You need a new tire if any of the following statements are true: D You can see the indicators at three or more places around the tire. D You can see cord or fabric showing through the tire’s rubber. D The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric.
Uniform Tire Quality Grading CAUTION: Mixing tires could cause you to lose control while driving. If you mix tires of different sizes or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes may also cause damage to your vehicle. Be sure to use the same size and type tires on all wheels. CAUTION: If you use bias-ply tires on your vehicle, the wheel rim flanges could develop cracks after many miles of driving.
Treadwear Temperature -- A, B, C The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and a half (1 1/2) times as well on the government course as a tire graded 100.
Wheel Alignment and Tire Balance The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. Scheduled wheel alignment and wheel balancing are not needed. However, if you notice unusual tire wear or your vehicle pulling one way or the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalanced.
NOTICE: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance and tire or tire chain clearance to the body and chassis. See “Changing a Flat Tire” in the Index for more information. Used Replacement Wheels CAUTION: Putting a used wheel on your vehicle is dangerous. You can’t know how it’s been used or how far it’s been driven. It could fail suddenly and cause an accident.
NOTICE: (Continued) If you have a tire size other than P265/75R16, LT265/75R16, P265/70R16 or P265/70R17, use tire chains only where legal and only when you must. Use chains that are the proper size for your tires. Install them on the tires of the rear axle. Don’t use chains on the tires of the front axle. Tighten them as tightly as possible with the ends securely fastened. Drive slowly and follow the chain manufacturer’s instructions.
Don’t use any of these unless this manual says you can. In many uses, these will damage your vehicle: D Alcohol D Laundry Soap D Bleach D Reducing Agents Cleaning the Inside of Your Vehicle Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl, leather, plastic and painted surfaces with a clean, damp cloth. Cleaning of Fabric/Carpet Your dealer has two cleaners, Multi-Purpose Interior Cleaner and Capture Non-Solvent Dry Spot and Soil Remover for cleaning fabric and carpet.
Special Fabric Cleaning Problems Cleaning Vinyl 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: Use warm water and a clean cloth. 1. Carefully scrape off excess stain, then sponge the soiled area with cool water. D Things like tar, asphalt and shoe polish will stain if 2. If a stain remains, follow the multi-purpose interior cleaner instructions described earlier.
Cleaning the Top of the Instrument Panel Cleaning Glass Surfaces 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. 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.
Grime from the windshield will stick to the wiper blades and affect their performance. Clean the blade by wiping vigorously with a cloth soaked in full-strength windshield washer solvent. Then rinse the blade with water. Check the wiper blades and clean them as necessary; replace blades that look worn. Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth at least every six months.
Your vehicle may have a “basecoat/clearcoat” paint finish. The clearcoat gives more depth and gloss to the colored basecoat. Always use waxes and polishes that are non-abrasive and made for a basecoat/clearcoat paint finish. NOTICE: Machine compounding or aggressive polishing on a basecoat/clearcoat paint finish may dull the finish or leave swirl marks.
Use chrome polish only on chrome-plated wheels, but avoid any painted surface of the wheel, and buff off immediately after application. Don’t take your vehicle through an automatic car wash that has silicon carbide tire cleaning brushes. These brushes can also damage the surface of these wheels.
Underbody Maintenance Chemical Paint Spotting Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, accelerated corrosion (rust) can occur on the underbody parts such as fuel lines, frame, floor pan and exhaust system even though they have corrosion protection. Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on your vehicle.

Vehicle Identification Number (VIN) Engine Identification The 8th character in your VIN is the engine code. This code will help you identify your engine, specifications and replacement parts. Service Parts Identification Label You’ll find this label located in the glove box. It’s very helpful if you ever need to order parts. On this label is: This is the legal identifier for your vehicle. It appears on a plate in the front corner of the instrument panel, on the driver’s side.
Electrical System Windshield Wipers Add-On Electrical Equipment The windshield wiper motor is protected by an internal circuit breaker and a fuse. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools. If the overload is caused by some electrical problem and not snow, etc., be sure to get it fixed. NOTICE: Don’t add anything electrical to your vehicle unless you check with your dealer first.
If you ever have a problem on the road and don’t have a spare fuse, you can borrow one that has the same amperage. Just pick some feature of your vehicle that you can get along without -- like the radio or cigarette lighter -- and use its fuse, if it is the correct amperage. Replace it as soon as you can. You may have spare fuses located behind the fuse block access door. These can be used to replace a bad fuse. However, make sure it is of the correct amperage.

✍ 6-68 NOTES
Section 7 Maintenance Schedule This section covers the maintenance required for your vehicle. Your vehicle needs these services to retain its safety, dependability and emission control performance.
Introduction Your Vehicle and the Environment Proper vehicle maintenance not only helps to keep your vehicle in good working condition, but also helps the environment. All recommended maintenance procedures are important. Improper vehicle maintenance can even affect the quality of the air we breathe. Improper fluid levels or the wrong tire inflation can increase the level of emissions from your vehicle.
How This Section is Organized This maintenance schedule is divided into five parts: “Part A: Scheduled Maintenance Services” shows what to have done and how often. Some of these services can be complex, so unless you are technically qualified and have the necessary equipment, you should let your dealer’s service department or another qualified service center do these jobs. CAUTION: Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, you can be seriously injured.
Part A: Scheduled Maintenance Services Using Your Maintenance Schedule We at General Motors want to help you keep your vehicle in good working condition. But we don’t know exactly how you’ll drive it. You may drive very short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands or in many other ways.
Scheduled Maintenance The services shown in this schedule up to 100,000 miles (166 000 km) should be performed after 100,000 miles (166 000 km) at the same intervals. The services shown at 150,000 miles (240 000 km) and 200,000 miles (332 000 km) should be performed at the same intervals after 150,000 miles (240 000 km) and 200,000 miles (332 000 km). See “Owner Checks and Services” and “Periodic Maintenance Inspections” following. Footnotes [ The U.S.
Scheduled Maintenance Engine Oil and Chassis Lubrication Scheduled Maintenance Change engine oil and filter as indicated by the GM Oil Life Systemt (or every 12 months, whichever occurs first). Reset the system. The system will show you when to change the oil -- usually between 3,000 miles (5 000 km) and 7,500 miles (12 500 km) since your last oil change. Under severe conditions, the indicator may come on before 3,000 miles (5 000 km).

Part B: Owner Checks and Services Listed in this part are owner checks and services which should be performed at the intervals specified to help ensure the safety, dependability and emission control performance of your vehicle. Be sure any necessary repairs are completed at once. Whenever any fluids or lubricants are added to your vehicle, make sure they are the proper ones, as shown in Part D.
At Least Twice a Year Restraint System Check Make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired. Have any torn or frayed safety belts replaced. Also look for any opened or broken air bag coverings, and have them repaired or replaced.
Weatherstrip Lubrication Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth. During very cold, damp weather more frequent application may be required. (See “Recommended Fluids and Lubricants” in the Index.) Automatic Transmission Check Check the transmission fluid level; add if needed. See “Automatic Transmission Fluid” in the Index. A fluid loss may indicate a problem. Check the system and repair if needed.
Starter Switch Check CAUTION: When you are doing this check, the vehicle could move suddenly. If it does, you or others could be injured. Follow the steps below. 1. Before you start, be sure you have enough room around the vehicle. 2. Firmly apply both the parking brake (see “Parking Brake” in the Index if necessary) and the regular brake. NOTE: Do not use the accelerator pedal, and be ready to turn off the engine immediately if it starts. 3. Try to start the engine in each gear.
Ignition Transmission Lock Check While parked, and with the parking brake set, try to turn the ignition key to LOCK in each shift lever position. D The key should turn to LOCK only when the shift lever is in PARK (P). D The key should come out only in LOCK. Parking Brake and Automatic Transmission PARK (P) Mechanism Check CAUTION: Park on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular brake, set the parking brake.
Part C: Periodic Maintenance Inspections Listed in this part are inspections and services which should be performed at least twice a year (for instance, each spring and fall). You should let your dealer’s service department or other qualified service center do these jobs. Make sure any necessary repairs are completed at once. Proper procedures to perform these services may be found in a service manual. See “Service and Owner Publications” in the Index.
Throttle System Inspection Brake System Inspection Inspect the throttle system for interference or binding, and for damaged or missing parts. Replace parts as needed. Replace any components that have high effort or excessive wear. Do not lubricate accelerator and cruise control cables. Inspect the complete system. Inspect brake lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition.
