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. Also see “Warning Lights and Gages” in the Index.

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 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. You can adjust the seat with this lever located at the front of the seat. 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.
Power Lumbar Control (If Equipped) Reclining Seatbacks 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 rocker switch. Let go of the switch when the lower seatback reaches the desired level of support. To decrease support, press and hold the rear of the rocker switch. Let go of the switch when the lower seatback reaches the desired level of support.
CAUTION: But don’t have a seatback reclined if your vehicle is moving. 1-4 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 because it won’t be against your body. Instead, it will be in front of you. In a crash you could go into it, receiving neck or other injuries. The lap belt can’t do its job either.
Head Restraints Seatback Latches The front seatback folds forward to let you access the rear of the cab. To fold the seatback, pull the easy entry lever located on the outboard side of the seat. To return the seatback to the upright position, push the seatback rearward until it latches. Then it will be locked into place. CAUTION: If the seatback isn’t locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there.
Safety Belts: They’re for Everyone This part of the manual tells you how to use safety belts properly. It also tells you some things you should not do with safety belts. CAUTION: Don’t let anyone ride where he or she can’t wear a safety belt properly. If you are in a crash and you’re not wearing a safety belt, your injuries can be much worse. You can hit things inside the vehicle or be ejected from it. You can be seriously injured or killed. In the same crash, you might not be if you are buckled up.
In most states and Canadian provinces, the law says to wear safety belts. Here’s why: They work. Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. You never know if you’ll be in a crash. If you do have a crash, you don’t know if it will be a bad one. A few crashes are mild, and some crashes can be so serious that even buckled up a person wouldn’t survive. But most crashes are in between. In many of them, people who buckle up can survive and sometimes walk away.
Put someone on it. 1-8 Get it up to speed. Then stop the vehicle. The rider doesn’t stop.
The person keeps going until stopped by something. or the instrument panel ... In a real vehicle, it could be the windshield ...
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? or the safety belts! With safety belts, you slow down as the vehicle does. You get more time to stop. You stop over more distance, and your strongest bones take the forces. That’s why safety belts make such good sense. 1-10 A: You could be -- whether you’re wearing a safety belt or not.
Q: If I’m a good driver, and I never drive far from home, why should I wear safety belts? A: You may be an excellent driver, but if you’re in an accident -- even one that isn’t your fault -- you and your passengers can be hurt. Being a good driver doesn’t protect you from things beyond your control, such as bad drivers. Most accidents occur within 25 miles (40 km) of home. And the greatest number of serious injuries and deaths occur at speeds of less than 40 mph (65 km/h).
3. Pick up the latch plate and pull the belt across you. Don’t let it get twisted. 4. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. If the belt isn’t long enough, see “Safety Belt Extender” at the end of this section. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 1-12 The lap part of the belt should be worn low and snug on the hips, just touching the thighs.
Shoulder Belt Height Adjuster Before you begin to drive, move the shoulder belt adjuster to the height that is right for you. To move it down, push in at the word PRESS and move the height adjuster to the desired position. You can move the adjuster up just by pushing up on the shoulder belt guide. After you move the adjuster to where you want it, try to move it down without pushing in to make sure it has locked into position.
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 your belt goes over an armrest like this. The belt would be much too high. In a crash, you can slide under the belt. The belt force would then be applied at the abdomen, not at the pelvic bones, and that could cause serious or fatal injuries. Be sure the belt goes under the armrests. A: The belt is over an armrest.
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. Lap Belt Right Front Passenger Position To learn how to wear the right front passenger’s safety belt properly, see “Driver Position” earlier in this section.
Children Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle.
CAUTION: (Continued) For example, in a crash at only 25 mph (40 km/h), a 12-lb. (5.5 kg) baby will suddenly become a 240-lb. (110 kg) force on a person’s arms. A baby should be secured in an appropriate restraint. CAUTION: People should never hold a baby in their arms while riding in a vehicle. A baby doesn’t weigh much -- until a crash. During a crash a baby will become so heavy it is not possible to hold it.
Q: What are the different types of add-on child restraints? A: Add-on child restraints, which are purchased by the vehicle’s owner, are available in four basic types. Selection of a particular restraint should take into consideration not only the child’s weight, height and age but also whether or not the restraint will be compatible with the motor vehicle in which it will be used. For most basic types of child restraints, there are many different models available.
CAUTION: Restraint Systems for Children The body structure of a young child is quite unlike that of an adult or older child, for whom the safety belts are designed. A young child’s hip bones are still so small that vehicle’s regular safety belt may not remain low on the hip bones, as it should. Instead, it may settle up around the child’s abdomen. In a crash, the belt would apply force on a body area that’s unprotected by any bony structure. This alone could cause serious or fatal injuries.
A rear-facing infant seat (B) provides restraint with the seating surface against the back of the infant. The harness system holds the infant in place and, in a crash, acts to keep the infant positioned in the restraint. A forward-facing child seat (C-E) provides restraint for the child’s body with the harness and also sometimes with surfaces such as T-shaped or shelf-like shields.
Q: A: How do child restraints work? A child restraint system is any device designed for use in a motor vehicle to restrain, seat, or position children. A built-in child restraint system is a permanent part of the motor vehicle. An add-on child restraint system is a portable one, which is purchased by the vehicle’s owner. For many years, add-on child restraints have used the adult belt system in the vehicle. To help reduce the chance of injury, the child also has to be secured within the restraint.
When choosing a child restraint, be sure the child restraint is designed to be used in a vehicle. If it is, it will have a label saying that it meets federal motor vehicle safety standards. Where to Put the Restraint 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.
If you need to have an anchor installed, your dealer can obtain a kit with anchor hardware and installation instructions specifically designed for this vehicle. The dealer can then install the anchor for you. This work will be done for you free of charge. Or, you may install the anchor yourself using the instructions provided in the kit. Securing a Child Restraint in a Center Seat Position In Canada, the law requires that forward-facing child restraints have a top strap, and that the strap be anchored.
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. 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. 3. Run the vehicle’s safety belt through or around the restraint. The child restraint instructions will show you how.
5. To tighten the belt, pull its free end while you push down on the child restraint. If you’re using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt. Securing a Child Restraint in the Right Front Seat Position 6. Push and pull the child restraint in different directions to be sure it is secure. To remove the child restraint, just unbuckle the vehicle’s safety belt.
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 lap belt all the way out of the retractor to set the lock.
5. To tighten the belt, feed the lap belt back into the retractor while you push down on the child restraint. If you’re using a forward-facing child restraint, you may find it helpful to use your knee to push down on the child restraint as you tighten the belt. 6. Push and pull the child restraint in different directions to be sure it is secure. To remove the child restraint, just unbuckle the vehicle’s safety belt and let it go back all the way.
Older Children Q: A: What is the proper way to wear safety belts? If possible, an older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips, just touching the top of the thighs. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash.
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.
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.
Windows CAUTION: Leaving children in a vehicle with the windows closed is dangerous. A child can be overcome by the extreme heat and can suffer permanent injuries or even death from heat stroke. Never leave a child alone in a vehicle, especially with the windows closed in warm or hot weather. Manual Windows Turn the hand crank on each door to raise or lower the manual windows.
Power Windows (If Equipped) The driver’s door also has a switch for the passenger window. The power windows will work when the ignition has been turned to ACCESSORY or RUN. Press the rear of the switch to lower the window. Press the front of the switch to raise the window. The driver’s window also has an express-down feature that allows the window to be lowered without holding the switch. Press and hold AUTO for one second to activate the express-down mode.
Keys CAUTION: Leaving children in a vehicle with the ignition key is dangerous for many reasons. A child or others could be badly injured or even killed. They could operate the power windows or other controls or even make the vehicle move. Don’t leave the keys in a vehicle with children.
Your vehicle has one double-sided key for the ignition and the door locks. Door Locks CAUTION: If you ever lose your keys, your dealer will be able to assist you with obtaining new ones. NOTICE: Your vehicle has a number of new features that can help prevent theft. You can have a lot of trouble getting into your vehicle if you ever lock your key inside. You may even have to damage your vehicle to get in. So be sure you have an extra key. Unlocked doors can be dangerous.
There are several ways to lock and unlock your vehicle. Power Door Locks (If Equipped) From the outside, use your key or the keyless entry system, if your vehicle has this feature. Press the top of the power door lock switch, marked LOCK, on either door to lock both doors at once. Press the ribbed side of the switch to unlock both doors at once. To lock the door from the inside, slide the manual lock located on your door down. Leaving Your Vehicle To unlock the door, slide the manual lock up.
Keyless Entry System (If Equipped) If your vehicle has this feature, you can lock and unlock your doors from about 3 feet (1 m) up to 30 feet (9 m) away using the remote keyless entry transmitter supplied with your vehicle. Your keyless entry system operates on a radio frequency subject to Federal Communications Commission (FCC) Rules and with Industry Canada. This device complies with Part 15 of the FCC Rules.
Operation Press the LOCK button to lock both doors. The interior lamps will come on for two seconds as soon as all the doors are closed. If you press the LOCK button twice the horn will chirp to confirm that the doors have locked. This will only occur if the transmitter has been programmed with the ignition off. If you do not want the horn to chirp as a confirmation that the doors have locked or unlocked, please consult your dealer.
Battery Replacement To replace the battery, do the following: Under normal use, the battery in your remote keyless entry transmitter should last about two years. You can tell the battery is weak if the transmitter won’t work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it’s probably time to change the battery. NOTICE: When replacing the battery, use care not to touch any of the circuitry.
Resynchronization Resynchronization may be necessary due to the security method used by this system. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal it has been sent previously. This prevents anyone from recording and playing back the signal from the transmitter. When you park your vehicle and open the driver’s door, you’ll hear a tone reminding you to remove your key from the ignition and take it with you. Always do this.
PasslockR Your vehicle is equipped with the Passlock theft-deterrent system. Passlock is a passive theft-deterrent system. Passlock enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder is tampered with, fuel is disabled. During normal operation, the SECURITY light will go off approximately five seconds after the key is turned to RUN.
Ignition Positions You can use the key to turn the ignition switch to five different positions. LOCK (B): This position locks your ignition, steering wheel and transmission. It’s a theft-deterrent feature. You will only be able to remove your key when the ignition is turned to LOCK. 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.
To remove the key, turn the key to OFF, press and hold the button and turn the key to LOCK. Do not hold the button in while turning the key to OFF. NOTICE: If your key seems stuck in LOCK and you can’t turn it, be sure you are using the correct key; if so, is it all the way in? If it is, then turn the steering wheel left and right while you turn the key hard. But turn the key only with your hand. Using a tool to force it could break the key or the ignition switch.
Manual Transmission The gear selector should be in NEUTRAL and the parking brake engaged. Hold the clutch pedal to the floor and start the engine. Your vehicle won’t start if the clutch pedal is not all the way down -- that’s a safety feature. 1. With your foot off 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.
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. To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord.
Automatic Transmission Operation PARK (P): This position locks your rear wheels. It’s the best position to use when you start your engine because your vehicle can’t move easily. CAUTION: There are several different positions for your shift lever. If your vehicle is equipped with an automatic transmission, it features an electronic shift position indicator within the instrument panel cluster. This display must be powered any time the shift lever is capable of being moved out of PARK (P).
REVERSE (R): Use this gear to back up. CAUTION: NOTICE: Shifting to REVERSE (R) while your vehicle is moving forward could damage your transmission. Shift to REVERSE (R) only after your vehicle is stopped. 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 the engine when you’re already moving, use NEUTRAL (N) only.
B AUTOMATIC OVERDRIVE ( ): This position is for normal driving. If you need more power for passing, and you’re: THIRD (3): This position is also used for normal driving, however it offers more power and lower fuel economy than AUTOMATIC OVERDRIVE ( ). D Going less than about 35 mph (56 km/h), push your SECOND (2): This position gives you more power, but lower fuel economy. You can use SECOND (2) on hills.
FIRST (1): This position gives you even more power, but lower fuel economy than SECOND (2). You can use it on very steep hills, or in deep snow or mud. If the selector lever is put in FIRST (1) while the vehicle is moving forward, the transmission won’t shift into first gear until the vehicle is going slowly enough. Manual Transmission Operation 5-Speed Here’s how to operate your transmission. NOTICE: If your rear wheels can’t rotate, don’t try to drive.
FIRST (1): Press the clutch pedal and shift into FIRST (1). Then, slowly let up on the clutch pedal as you press the accelerator pedal. Shift into FIRST (1) only when the vehicle is below 5 mph (8 km/h). If you try to shift down into FIRST (1) at excessive vehicle speeds, the shift lever will not move into the FIRST (1) position until vehicle speed is reduced. FOURTH (4) and FIFTH (5): Shift into the higher forward gears the same way you do for THIRD (3).
Shift Speeds CAUTION: If you skip a gear when you downshift, you could lose control of your vehicle. You could injure yourself or others. Don’t shift down more than one gear at a time when you downshift. If your speed drops below 20 mph (32 km/h), or if the engine is not running smoothly, you should downshift to the next lower gear. You may have to downshift two or more gears to keep the engine running smoothly or for good performance.
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 come on. To release the parking brake, hold the regular brake pedal down. Pull the lever, located just above the parking brake pedal, marked BRAKE RELEASE. NOTICE: Driving with the parking brake on can cause your rear brakes to overheat.
Shifting Into PARK (P) (Automatic Transmission Only) 2. Move the shift lever into PARK (P) position like this: 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 (Automatic Transmission Only) CAUTION: D Move the lever up as far as it will go. It can be dangerous to leave your vehicle with the engine running. Your vehicle could move suddenly if the shift lever is not fully in PARK (P) with the parking brake firmly set. And, if you leave the vehicle with the engine running, it could overheat and even catch fire. You or others could be injured. Don’t leave your vehicle with the engine running unless you have to. 3.
Torque Lock (Automatic Transmission) If you are parking on a hill and you don’t shift your transmission into PARK (P) properly, the weight of the vehicle may put too much force on the parking pawl in the transmission. You may find it difficult to pull the shift lever out of PARK (P). This is called “torque lock.” To prevent torque lock, set the parking brake and then shift into PARK (P) properly before you leave the driver’s seat. To find out how, see “Shifting Into PARK (P)” in the Index.
Parking Your Vehicle (Manual Transmission Models Only) Parking Over Things That Burn Before you get out of your vehicle, move the shift lever into REVERSE (R), and firmly apply the parking brake. Once the shift lever has been placed into REVERSE (R) with the clutch pedal pressed in, you can turn the ignition key to OFF, remove the key and release the clutch. If you are parking on a hill, or if you are pulling a trailer, see “Towing a Trailer” in the Index.
Engine Exhaust CAUTION: Engine exhaust can kill. It contains the gas carbon monoxide (CO), which you can’t see or smell. It can cause unconsciousness and death. You might have exhaust coming in if: D Your exhaust system sounds strange or different. D Your vehicle gets rusty underneath. D Your vehicle was damaged in a collision. D Your vehicle was damaged when driving over high points on the road or over road debris. D Repairs weren’t done correctly.
CAUTION: It can be dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll. Don’t leave your vehicle when the engine is running unless you have to. If you’ve left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle won’t move, even when you’re on fairly level ground, always set your parking brake and move the shift lever to PARK (P).
Turn Signal/Multifunction Lever Turn 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 located on the instrument panel cluster will flash in the direction of the turn or lane change.
Headlamp High/Low-Beam Changer To change the headlamps from low to high beam or high to low beam, pull the multifunction lever all the way toward you. Then release it. When the high beams are on, this light located on the instrument panel cluster also will be on. Windshield Wipers You control the windshield wipers by turning the knob with the wiper symbol on it. For a single wiping cycle, turn the knob to MIST. Hold it there until the wipers start, then let go. The wipers will stop after one cycle.
Windshield Washer At the top of the lever, there’s a paddle with the word PUSH on it. To spray washer fluid on the windshield, push the paddle. Washer fluid will spray as long as you push the paddle. When you let go of the paddle, the wipers will continue to wipe for a few seconds and then either stop or return to the preset speed. The use of a hood-mounted air deflector may adversely affect windshield wiper and washer performance.
Setting Cruise Control 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. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause needless wheel spinning, and you could lose control. Don’t use cruise control on slippery roads.
Resuming a Set Speed Suppose you set your cruise control at a desired speed and then you apply the brake. This, of course, shuts off the cruise control. But you don’t need to reset it. D Move the cruise switch from ON to R/A. Hold it there until you get up to the speed you want, and then release the switch. (To increase your speed in very small amounts, move the switch to R/A briefly. Each time you do this, your vehicle will go about 1 mph (1.6 km/h) faster.
Using Cruise Control on Hills Exterior Lamps How well your cruise control will work on hills depends upon your speed, load and the steepness of the hills. When going up steep hills, you may have to step on the accelerator pedal to maintain your speed. If the steepness of the hill causes the vehicle speed to drop more than 15 mph (24 km/h) below the set speed, your cruise control will automatically disengage. When going downhill, you may have to brake or shift to a lower gear to keep your speed down.
Turn the knob clockwise to the parking lamp symbol, to turn on the following: D D D D D D Parking Lamps Sidemarker Lamps Clearance Lamps Taillamps License Plate Lamps Instrument Panel Lights Turn the knob clockwise again to the master lighting symbol to turn on all the lamps listed as well as the headlamps. Turn the knob counterclockwise, to OFF, to turn off your lamps. You can turn your headlamps from high to low beams by pulling on the turn signal/multifunction lever.
When you turn off the headlamp knob, the regular lamps will go off, and your headlamps will change to the reduced brightness of DRL. To idle your vehicle with the DRL off, set the parking brake. The DRL will stay off until you release the parking brake. Illuminated Entry Your vehicle is equipped with an illuminated entry feature. As with any vehicle, you should turn on the regular headlamp system when you need it. When a door is opened, the dome lamps will come on if the dome lamp button is out.
Dome Lamp The dome lamp will come on when you open a door. You can also turn the dome lamp on by turning the thumbwheel, located next to the parking lamps and headlamp knob, all the way up to the second notch. In this position, the dome lamp will remain on whether a door is opened or closed. You can use the DOME OVERRIDE button, located below the parking lamp and headlamp knob, to set the dome lamp to come on automatically when a door is opened, or to remain off.

Instrument Panel Cluster United States automatic transmission shown, Canada similar Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You’ll know how fast you’re going, about how much fuel you have and many other things you’ll need to know to drive safely and economically.
Speedometer and Odometer Your speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). Your odometer shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). Tamper-Resistant Odometer Your odometer is tamper-resistant. The odometer will show silver lines between the numbers if someone tries to turn it back. You may wonder what happens if your vehicle needs a new odometer installed.
Warning Lights, Gages and Indicators This part describes the warning lights and gages that may be on your vehicle. The pictures will help you locate them. Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to your warning lights and gages could also save you or others from injury. Warning lights come on when there may be or is a problem with one of your vehicle’s functions.
Charging System Indicator Light This light should come on briefly when you turn on the ignition, before starting the engine, as a check to show you it is working. After the engine starts, the light should go out. If it stays on or comes on while you are driving, you may have a problem with your charging system. It could indicate a problem with the generator drive belt, or some other charging system problem. Have it checked right away. Driving while this light is on could drain your battery.
You can only drive for a short time with the reading in either warning zone. If you must drive, turn off all unnecessary accessories. Readings in either warning zone indicate a possible problem in the electrical system. Have the vehicle serviced as soon as possible. Brake System Warning Light When the ignition is on, the brake system warning light will come on when you set your parking brake. The light will stay on if your parking brake doesn’t release fully.
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. If the light stays on, or comes on when you’re driving, your vehicle needs service. If the regular brake system warning light isn’t on, you still have brakes, but you don’t have anti-lock brakes. If the regular brake system warning light is also on, you don’t have anti-lock brakes and there’s a problem with your regular brakes.
Malfunction Indicator Lamp (Service Engine Soon Light in the United States or Check Engine Light in Canada) (Gasoline Engine) United States Canada Your vehicle is equipped with a computer which monitors operation of the fuel, ignition and emission control systems. 2-52 This system is called OBD II (On-Board Diagnostics-Second Generation) and is intended to assure that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment.
NOTICE: Modifications made to the engine, transmission, exhaust, intake or fuel system of your vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect your vehicle’s emission controls and may cause the SERVICE ENGINE SOON or CHECK ENGINE light to come on. Modifications to these systems could lead to costly repairs not covered by your warranty. This may also result in a failure to pass a required Emission Inspection/Maintenance test.
If the Light Is On Steady You may be able to correct the emission system malfunction by considering the following: This will be detected by the system and cause the light to turn on. Did you recently put fuel into your vehicle? If you experience one or more of these conditions, change the fuel brand you use. It will require at least one full tank of the proper fuel to turn the light off. If so, reinstall the fuel cap, making sure to fully install the cap. See “Filling Your Tank” in the Index.
Your vehicle will not pass this inspection if the OBD (on-board diagnostic) system determines that critical emission control systems have not been completely diagnosed by the system. The vehicle would be considered not ready for inspection. This can happen if you have recently replaced your battery or if your battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This may take several days of routine driving.
NOTICE: Damage to your engine from neglected oil problems can be costly and is not covered by your warranty. Oil pressure may vary with engine speed, outside temperature and oil viscosity, but readings above the low pressure zone indicate the normal operating range. A reading in the low pressure zone may be caused by a dangerously low oil level or some other problem causing low oil pressure. Check your oil as soon as possible.
Up Shift Light (If Equipped) This light is used on models with manual transmissions. The SHIFT indicator light will help you get the best fuel economy. See “Shift Light” or “Shift Speeds” in this section for more information. Daytime Running Lamps Indicator Light This light goes on whenever the DRL are on. Check Gages Light This light will come on briefly when you are starting the engine. If the light comes on and stays on while you are driving, it could indicate a problem with your vehicle.
The gage will first indicate empty before you are out of fuel, and you should get more fuel as soon as possible. Fuel Gage Here are four situations you may experience with your fuel gage. None of these indicate a problem with the fuel gage. D At the gas station, the fuel pump shuts off before the gage reads full. D It takes a little more or less fuel to fill up than the United States Canada The fuel gage, when the ignition is on, tells you about how much fuel you have left in your tank.
Section 3 Comfort Controls and Audio Systems In this section, you’ll find out how to operate the comfort control and audio systems offered with your vehicle. Be sure to read about the particular systems supplied with your vehicle.
Comfort Controls Heater Control System Temperature Knob The middle knob on the control panel lets you select the temperature of the air flowing into the passenger area of your vehicle. This knob will allow you to adjust the air temperature independently of the fan knob settings. Turn the knob clockwise, toward the red area, for warmer air. Turn the knob counterclockwise, toward the blue area, for cooler air. Mode Knob The right knob on the control panel allows you to choose the direction of air delivery.
Heater and Air Conditioning Control System (If Equipped) Temperature Knob The middle knob on the control panel lets you select the relative temperature of the air flowing into the passenger area of your vehicle. This knob will allow you to adjust the relative air temperature independently of the fan and knob settings. Turn the knob clockwise, toward the red area, for warmer air. Turn the knob counterclockwise, toward the blue area, for cooler air.
Air Conditioning Heating 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 heater works best if you keep your windows closed while using it. On cold days, use the HEATER or BI-LEVEL setting with the temperature knob in the red area. A/C: Press this button to turn the air conditioning on and off.
Ventilation System For mild outside temperatures when little heating or cooling is needed, use VENT to direct outside air through your vehicle. Air will flow through the instrument panel outlets. Your vehicle’s ventilation system supplies outside air to the inside of your vehicle when it is moving. With the side windows closed, air will flow into the front air inlet grilles, through the vehicle, and out the air exhaust valves.
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 fan to HI for a few moments before driving. This helps clear the intake ducts of snow and moisture, and reduces the chance of fogging the inside of your windows. D Keep the air path under the front seats clear of objects.

Tune in the desired station. TREB: Slide this lever up or down to increase or decrease treble. If a station is weak or noisy, you may want to decrease the treble. 2. Press SET. (SET will appear on the display.) 3. Press two adjoining buttons at the same time, within five seconds.
Playing a Cassette Tape CD Adapter Kits Your tape player is built to work best with tapes that are up to 30 to 45 minutes long on each side. Tapes longer than that are so thin they may not work well in this player. It is possible to use a portable CD player adapter kit with your cassette tape player after activating the bypass feature on your tape player. Once the tape is playing, use the knobs for VOLUME, BAL, FADE, BASS and TREB just as you do for the radio.
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.
You may also choose a non-scrubbing action, wet-type cleaner which uses a cassette with a fabric belt to clean the tape head. This type of cleaning cassette will not eject on its own. A non-scrubbing action cleaner may not clean as thoroughly as the scrubbing type cleaner. The use of a non-scrubbing action, dry-type cleaning cassette is not recommended. Fixed Mast Antenna After you clean the player, press and hold EJECT for five seconds to reset the CLN indicator.
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.
It’s the amount of alcohol that counts. For example, if the same person drank three double martinis (3 ounces or 90 ml of liquor each) within an hour, the person’s BAC would be close to 0.12 percent. A person who consumes food just before or during drinking will have a somewhat lower BAC level. There is a gender difference, too. Women generally have a lower relative percentage of body water than men.
But the ability to drive is affected well below a BAC of 0.10 percent. Research shows that the driving skills of many people are impaired at a BAC approaching 0.05 percent, and that the effects are worse at night. All drivers are impaired at BAC levels above 0.05 percent. Statistics show that the chance of being in a collision increases sharply for drivers who have a BAC of 0.05 percent or above. A driver with a BAC level of 0.06 percent has doubled his or her chance of having a collision.
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. This can help you steer around the obstacle while braking hard. Here’s how anti-lock works. Let’s say the road is wet. You’re driving safely. Suddenly an animal jumps out in front of you. You slam on the brakes and continue braking. Here’s what happens with ABS. A computer senses that wheels are slowing down.
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. Steering Using Anti-Lock Steering Tips Don’t pump the brakes. Just hold the brake pedal down firmly and let anti-lock work for you.
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. What should you do if this ever happens? Ease up on the accelerator pedal, steer the vehicle the way you want it to go, and slow down. Speed limit signs near curves warn that you should adjust your speed.
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 and an acceleration skid are best handled by easing your foot off the accelerator pedal. Driving at Night If your vehicle starts to slide, ease your foot off the accelerator pedal and quickly steer the way you want the vehicle to go. If you start steering quickly enough, your vehicle may straighten out. Always be ready for a second skid if it occurs. Of course, traction is reduced when water, snow, ice, gravel or other material is on the road.
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 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. Slow down, especially on higher speed roads. Your headlamps can light up only so much road ahead. In remote areas, watch for animals. If you’re tired, pull off the road in a safe place and rest.
Driving in Rain and on Wet Roads Rain and wet roads can mean driving trouble. On a wet road, you can’t stop, accelerate or turn as well because your tire-to-road traction isn’t as good as on dry roads. And, if your tires don’t have much tread left, you’ll get even less traction. It’s always wise to go slower and be cautious if rain starts to fall while you are driving. The surface may get wet suddenly when your reflexes are tuned for driving on dry pavement. The heavier the rain, the harder it is to see.
CAUTION: Wet brakes can cause accidents. They won’t work as well in a quick stop and may cause pulling to one side. You could lose control of the vehicle. After driving through a large puddle of water or a car wash, apply your brake pedal lightly until your brakes work normally. Hydroplaning Driving too fast through large water puddles or even going through some car washes can cause problems, too. The water may affect your brakes. Try to avoid puddles.
Driving Through Deep Standing Water NOTICE: If you drive too quickly through deep puddles or standing water, water can come in through your engine’s air intake and badly damage your engine. Never drive through water that is slightly lower than the underbody of your vehicle. If you can’t avoid deep puddles or standing water, drive through them very slowly. Driving Through Flowing Water CAUTION: Flowing or rushing water creates strong forces.
City Driving One of the biggest problems with city streets is the amount of traffic on them. You’ll want to watch out for what the other drivers are doing and pay attention to traffic signals. Here are ways to increase your safety in city driving: 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.
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.
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. After driving for any distance at higher speeds, you may tend to think you are going slower than you actually are.
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. CAUTION: D Keep your vehicle in good shape. Check all fluid 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. Your vehicle should not be towed with all four wheels on the ground. The transmission has no provisions for internal lubrication while being towed.
Loading Your Vehicle The Certification/Tire label also tells you the maximum weights for the front and rear axles, called Gross Axle Weight Rating (GAWR). To find out the actual loads on your front and rear axles, you need to go to a weigh station and weigh your vehicle. Your dealer can help you with this. Be sure to spread out your load equally on both sides of the centerline. Never exceed the GVWR for your vehicle, or the GAWR for either the front or rear axle.
CAUTION: Do not load your vehicle any heavier than the GVWR, or either the maximum front or rear GAWR. If you do, parts on your vehicle can break, and it can change the way your vehicle handles. These could cause you to lose control and crash. Also, overloading can shorten the life of your vehicle. NOTICE: Your warranty does not cover parts or components that fail because of overloading.
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 Don’t tow a trailer at all during the first 500 miles (800 km) your new vehicle is driven. Your engine, axle or other parts could be damaged.
3500HD Engine 6.5L Diesel 8.1L Weight of the Trailer Tongue Axle Ratio 4.63 5.13 Gross Combination Weight Rating 17,000 lbs. (7 718 kg) 17,000 lbs.* (7 718 kg) 4.63 5.13 19,000 lbs.* (8 626 kg) 19,000 lbs.* (8 626 kg) *Fifth wheel hitch rating; weight distributing hitch rating is limited to 10,000 lbs. (4 540 kg). The tongue load (A) of any trailer is an important weight to measure because it affects the total or gross weight of your vehicle.
If you’re using a weight-carrying hitch, the trailer tongue (A) should weigh 10 percent of the total loaded trailer weight (B). If you’re using a weight-distributing hitch, the trailer tongue (A) should weigh 12 percent of the total loaded trailer weight (B). After you’ve loaded your trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they aren’t, you may be able to get them right simply by moving some items around in the trailer.
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 inch (0.3 cc) of fluid from your vehicle’s master cylinder. Otherwise, both braking systems won’t work well. You could even lose your brakes. If everything checks out this far, make the brake tap at the port on the master cylinder that sends the fluid to the rear brakes.
Backing Up Turn Signals When Towing a Trailer Hold the bottom of the steering wheel with one hand. Then, to move the trailer to the left, just move that hand to the left. To move the trailer to the right, move your hand to the right. Always back up slowly and, if possible, have someone guide you. The arrows on your instrument panel will flash whenever you signal a turn or lane change. Properly hooked up, the trailer lamps will also flash, telling other drivers you’re about to turn, change lanes or stop.
If you have a manual transmission and you are towing a trailer, it’s better not to use FIFTH (5) gear. Just drive in FOURTH (4) gear (or, as you need to, a lower gear). When towing at high altitude on steep uphill grades, consider the following: Engine coolant will boil at a lower temperature than at normal altitudes. If you turn your engine off immediately after towing at high altitude on steep uphill grades, your vehicle may show signs similar to engine overheating.
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. this manual, and the Index will help you find them quickly. If you’re trailering, it’s a good idea to review these sections before you start your trip. Check periodically to see that all hitch nuts and bolts are tight.
Power Take-Off (PTO) (Manual Transmission) (If Equipped) To engage a PTO on a vehicle with a manual transmission: 1. Hold the clutch pedal down. NOTICE: 2. Set the parking brake. If you have a PTO that will exceed 35 hp installed on your vehicle, it could damage the transmission. When having a PTO installed on your vehicle, make sure that it will not exceed 35 hp. 4. Engage the PTO. Refer to the manufacturer’s or installer’s instructions on electrically engaged PTOs.
Using PTO speed control in Preset Mode (Factory Setting): NOTICE: 1. Engage the PTO. 2. Select PARK (P) or NEUTRAL (N) range. Apply the parking brake if NEUTRAL (N) is selected. Torque Converter Clutch (TCC) is not available in NEUTRAL (N) and is available only in PARK when speed is above 1100 rpm. Using a PTO for more than four hours without driving your vehicle can damage the transmission.
Using PTO speed control in Variable Mode (Mobile): 1. Engage the PTO. 2. Vehicle speed must be greater than 5 mph for vehicles equipped with gasoline engines or greater than 0 mph for vehicles equipped with diesel engines. 3. Make sure your foot is off the brake pedal (and off the clutch for vehicles equipped with a manual transmission). 4. Select the desired engine speed (with the foot pedal) and select SET on the PTO switch or with the cruise control.
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 located 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 (or batteries) have 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. 3.
CAUTION: Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. Be sure the batteries have enough water. You don’t need to add water to the ACDelcoR battery (or batteries) installed in every new GM vehicle. But if a battery has filler caps, be sure the right amount of fluid is there. If it is low, add water to take care of that first. If you don’t, explosive gas could be present.
8. Don’t let the other end touch metal. Connect it to the positive (+) terminal of the good battery. 7. Connect the red positive (+) cable to the positive (+) terminal of the vehicle with the dead battery. 9. Now connect the black negative (-) cable to the good battery’s negative (-) terminal. 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.
Attach the cable at least 18 inches (45 cm) away from the dead battery, but not near engine parts that move. The electrical connection is just as good there, but the chance of sparks getting back to the battery is much less. Jumper Cable Removal A. Heavy, Unpainted Metal Engine Part B. Good Battery C. Dead Battery 10. Now start the vehicle with the good battery and run the engine for awhile. 11. Try to start the vehicle with the dead battery. If it won’t start after a few tries, it probably needs service.
To disconnect the jumper cables from both vehicles, do the following: If your vehicle has a diesel engine, see “Engine Overheating” in the Diesel Engine Supplement. 1. Disconnect the black negative (-) cable from the heavy, unpainted metal engine part on the vehicle that had the dead battery. Overheated Engine Protection Operating Mode 2. Disconnect the black negative (-) cable from the negative (-) terminal on the vehicle with the good battery.
If Steam Is Coming From Your Engine CAUTION: Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned.
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 If you no longer have the overheat warning, you can drive. Just to be safe, drive slower for about 10 minutes. If the warning doesn’t come back on, you can drive normally. If the warning continues, pull over, stop, and park your vehicle right away. Climb a long hill on a hot day.
Cooling System (Gasoline Engine) 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 is boiling, don’t do anything else until it cools down. A. Coolant Recovery Tank B. Radiator Pressure Cap C.
When the engine is cold, the coolant level should be at or above the COLD mark. 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.
NOTICE: When adding coolant, it is important that you use only DEX-COOLR (silicate-free) coolant. If coolant other than DEX-COOL is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner -- at 30,000 miles (50 000 km) or 24 months, whichever occurs first. Damage caused by the use of coolant other than DEX-COOLR is not covered by your new vehicle warranty. If there seems to be no leak, start the engine again.
NOTICE: In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. Use the recommended coolant and the proper coolant mixture. CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Don’t spill coolant on a hot engine. When the coolant in the coolant recovery tank is at or above the COLD mark, start your vehicle.
CAUTION: Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the radiator pressure cap -- even a little -- they can come out at high speed. Never turn the cap when the cooling system, including the radiator pressure cap, is hot. Wait for the cooling system and radiator pressure cap to cool if you ever have to turn the pressure cap.
How to Add Coolant to the Radiator 2. Then keep turning the pressure cap, but now push down as you turn it. Remove the pressure cap. 1. You can remove the radiator pressure cap when the cooling system, including the radiator pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise until it first stops. (Don’t press down while turning the pressure cap.) If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left.
3. Fill the radiator with the proper DEX-COOLR coolant mixture, up to the base of the filler neck. See “Engine Coolant” in the Index for more information about the proper coolant mixture. 4. Then fill the coolant recovery tank to the COLD mark. 5. Put the cap back on the coolant recovery tank, but leave the radiator pressure cap off.
6. Start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan(s). 7. By this time, the coolant level inside the radiator filler neck may be lower. If the level is lower, add more of the proper DEX-COOLR coolant mixture through the filler neck until the level reaches the base of the filler neck. 5-18 8. Then replace the pressure cap.
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 Your truck, when new, included no tire changing equipment and no place to store a tire in the vehicle. Few drivers of these vehicles have the necessary equipment aboard to be able to change a flat tire safely. For example, you would need a truck jack that can lift several thousand pounds and a torque wrench that can generate several hundred foot-pounds (Newton-meters) of twisting force.
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.
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.
In Canada, look for the “Auto Makers’ Choice” label on the fuel pump. Adding Equipment to the Outside of Your Vehicle Things you might add to the outside of your vehicle can affect the airflow around it. This may cause wind noise and affect windshield washer performance. Check with your dealer before adding equipment to the outside of your vehicle. Fuel (Gasoline Engine) If your vehicle has a diesel engine, see “Diesel Fuel Requirements and Fuel System” in the Diesel Engine Supplement.
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.
NOTICE: Your vehicle was not designed for fuel that contains methanol. Don’t use it. It can corrode metal parts in your fuel system and also damage plastic and rubber parts. That damage wouldn’t be covered under your warranty. Fuels in Foreign Countries (Gasoline Engines) 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.
To remove the cap, turn it slowly to the left (counterclockwise). 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. Be careful not to spill gasoline.
Filling a Portable Fuel Container CAUTION: Never fill a portable fuel container while it is in your vehicle. Static electricity discharge from the container can ignite the gasoline vapor. You can be badly burned and your vehicle damaged if this occurs. To help avoid injury to you and others: D Dispense gasoline only into approved containers. D Do not fill a container while it is inside a vehicle, in a vehicle’s trunk, pickup bed or on any surface other than the ground.
Hood Release To open the hood, first pull the handle located near the lower left side of the instrument panel. Then go to the front of the vehicle and pull up on the secondary hood release, located just to the passenger’s side of the center of the grill. Lift the hood. Before closing the hood, be sure all filler caps are on properly. Pull down the hood and close it firmly.
Engine Compartment Overview When you open the hood, this is what you will see: A. B. C. D. E. Battery Air Filter Restriction Indicator Engine Air Cleaner/Filter Coolant Recovery Tank Radiator Pressure Cap F. Engine Oil Dipstick G. Automatic Transmission Dipstick (If Equipped) H. Engine Oil Fill I. Engine Cooling Fan J. Power Steering Fluid Reservoir K. Brake Fluid Reservoir L. Hydraulic Clutch Fluid Reservoir M. Windshield Washer Fluid Reservoir N.
Noise Control System The following information relates to compliance with federal noise emission standards for vehicles with a Gross Vehicle Weight Rating (GVWR) of more than 10,000 lbs. (4 536 kg). The Maintenance Schedule provides information on maintaining the noise control system to minimize degradation of the noise emission control system during the life of your vehicle. The noise control system warranty is given in your warranty booklet.
Engine Oil (Gasoline Engine) If your vehicle has a diesel engine, see “Engine Oil (Diesel Engine)” in the Diesel Engine Supplement. Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level. Checking Engine Oil It’s a good idea to check your engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground.
What Kind of Engine Oil to Use NOTICE: Don’t add too much oil. If your engine has so much oil that the oil level gets above the upper mark that shows the proper operating range, your engine could be damaged. The engine oil fill cap is located at the front of the engine. See “Engine Compartment Overview” in the Index for more information on location. Oils recommended for your vehicle can be identified by looking for the starburst symbol.
As in the chart shown previously, 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. _ _ NOTICE: Use only engine oil with the American Petroleum Institute Certified For Gasoline Engines starburst symbol. Failure to use the recommended oil can result in engine damage not covered by your warranty.
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. When to Change Engine Oil If any one of these is true for you, use the short trip/city maintenance schedule: D Most trips are less than 5 to 10 miles (8 to 16 km). This is particularly important when outside temperatures are below freezing. D Most trips include extensive idling (such as frequent driving in stop-and-go traffic).
Engine Air Cleaner/Filter (Gasoline Engines) The engine air cleaner/filter assembly has an indicator that lets you know when the engine air cleaner/filter is dirty and needs to be serviced. The indicator is located in the air intake tube between the engine air cleaner/filter and the engine. See “Owner Checks and Services” in the Index to determine when to check the indicator. Your engine air cleaner/filter is located between the battery and coolant recovery tank.
5. Install the duct and the filter into the engine air cleaner/filter housing. Make sure that the duct fits properly into the housing. To remove the engine air cleaner/filter: 1. Unhook the retaining clips and remove the cover. 2. Lift the filter and the connected duct out of the air cleaner/filter housing. Hold the duct and remove the filter by both pulling and twisting the filter away from the duct. Care should be taken to dislodge as little dirt as possible. 3.
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. Automatic Transmission Fluid If your vehicle has a diesel engine, see “Automatic Transmission Fluid” in the Diesel Supplement.
NOTICE: Too much or too little fluid can damage your transmission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to get an accurate reading if you check your transmission fluid. A cold fluid check can be made after the vehicle has been sitting for eight hours or more with the engine off, but this is used only as a reference. Let the engine run at idle for five minutes if outside temperatures are 50_F (10_C) or more.
Then, without shutting off the engine, follow these steps: 2. Push it back in all the way, wait three seconds and then pull it back out again. 3. Check both sides of the dipstick, and read the lower level. The fluid level must be in the COLD area, below the cross-hatched area, for a cold check or in the HOT area or cross-hatched area for a hot check. 1. The red transmission dipstick handle is located at the rear of the engine compartment, on the passenger’s side.
How to Add Fluid Manual Transmission Fluid 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 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).
Check the fluid level only when your engine is off, the vehicle is parked on a level place and the transmission is cool enough for you to rest your fingers on the transmission case. Then, follow these steps: How to Add Fluid Here’s how to add fluid. Refer to the Maintenance Schedule to determine what kind of fluid to use. See “Recommended Fluids and Lubricants” in the Index. 1. Remove the filler plug. 2. Add fluid at the filler plug hole.
When to Check and What to Use Refer to the Maintenance Schedule to determine how often you should check the fluid level in your clutch master cylinder reservoir and for the proper fluid. See “Owner Checks and Services” and “Recommended Fluids and Lubricants” in the Index. Rear Axle When to Check and Change Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant and when to change it. See “Scheduled Maintenance Services” in the Index.
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. Engine Coolant The cooling system in your vehicle is filled with DEX-COOLR engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOLR extended life coolant. The following explains your cooling system and how to add coolant when it is low.
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 gages work as they should. NOTICE: When adding coolant, it is important that you use only DEX-COOLR (silicate-free) coolant. If coolant other than DEX-COOL is added to the system, premature engine, heater core or radiator corrosion may result.
NOTICE: Checking Coolant 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. NOTICE: If you use the proper coolant, you don’t have to add extra inhibitors or additives which claim to improve the system.
The vehicle must be on a level surface. When your engine is cold, the coolant level should be at the COLD mark, or a little higher. When your engine is warm, the level should be up to the HOT mark, or a little higher. Adding Coolant If you need more coolant, add the proper DEX-COOLR coolant mixture at the coolant recovery tank. CAUTION: Turning the radiator pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly.
Radiator Pressure Cap (Gasoline Engine) The radiator pressure cap is located on the passenger’s side of the engine compartment. See “Engine Compartment Overview” in the Index for more information on location. NOTICE: Power Steering Fluid The power steering fluid reservoir cap is located at the front of the engine compartment. See “Engine Compartment Overview” in the Index for more information on location.
How to Check Power Steering Fluid Windshield Washer 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. What to Use The level should be at the FULL COLD mark. If necessary, add only enough fluid to bring the level up to the mark.
Open the cap labeled WASHER FLUID ONLY. Add washer fluid until the tank is full. Brakes Brake Fluid NOTICE: D When using concentrated washer fluid, D D D follow the manufacturer’s instructions for adding water. Don’t mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage your washer fluid tank and other parts of the washer system. Also, water doesn’t clean as well as washer fluid. Fill your washer fluid tank only three-quarters full when it’s very cold.
The other reason is that fluid is leaking out of the brake system. If it is, you should have your brake system fixed, since a leak means that sooner or later your brakes won’t work well, or won’t work at all. Checking 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.
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. NOTICE: D Using the wrong fluid can badly damage 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: With the wrong kind of fluid in your brake system, your brakes may not work well, or they may not even work at all.
Brake Wear Brake Pedal Travel Your vehicle has four-wheel disc brakes without wear indicators. If you ever hear a brake rubbing noise, have the brake linings inspected. See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble. Brake Adjustment NOTICE: Continuing to drive with worn-out brake pads could result in costly brake repair.
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. See “Engine Compartment Overview” in the Index for battery location. WARNING: Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.

Windshield Wiper Blade Replacement Windshield wiper blades should be inspected at least twice a year for wear and cracking. See “Wiper Blade Check” in the Index for more information. Replacement blades come in different types and are removed in different ways. For proper type and length, see “Normal Maintenance Replacement Parts” in the Index. Here’s how to remove the Shephard’s Hook type. To replace the windshield wiper blade assembly, do the following: 1.
Tires Your new vehicle comes with high-quality tires made by a leading tire manufacturer. If you ever have questions about your tire warranty and where to obtain service, see your GM Warranty booklet for details. CAUTION: (Continued) D Underinflated tires pose the same danger 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.
Inflation -- Tire Pressure The Certification/Tire label, which is on the rear edge of the driver’s door, or on the incomplete vehicle document in the cab, shows the correct inflation pressures for your tires when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). NOTICE: Don’t let anyone tell you that underinflation or overinflation is all right. It’s not.
Tire Inspection and Rotation Tires should be rotated every 6,000 to 8,000 miles (10 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See “When It’s Time for New Tires” and “Wheel Replacement” later in this section for more information. Also see “Dual Tire Operation” later in this section. The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle.
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. CAUTION: If the tread design for the front tires is different from the dual rear tires, always use the correct rotation pattern shown here when rotating your tires. The rear dual tires are rotated as a pair, and the inside rear tires become the outside rear tires.
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. Some commercial truck tires may not have treadwear indicators.
Tightening the Wheel Nuts All wheel nuts must be properly tightened. With a torque wrench, tighten the wheel nuts firmly in a crisscross sequence using the proper wheel nut torque. CAUTION: 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. Tighten with a torque wrench to the proper torque.
CAUTION: Rust or dirt on a 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. In an emergency, you can use a cloth or paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off. CAUTION: Never use oil or grease on studs or nuts.
Buying New Tires To find out what kind and size of tires you need, look at the Certification/Tire label. The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) number on each tire’s sidewall. When you get new tires, get ones with that same TPC Spec number. That way your vehicle will continue to have tires that are designed to give proper endurance, handling, speed rating, traction, ride and other things during normal service on your vehicle.
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.
Used Replacement Wheels 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. Whenever a wheel, wheel bolt or wheel nut is replaced on a dual wheel setup, check the wheel nut torque after 100, 1,000 and 6,000 miles (160, 1 600 and 10 000 km) of driving. For proper torque, see “Wheel Nut Torque” in the Index.
Tire Chains NOTICE: Don’t use tire chains. They can damage your vehicle because there’s not enough clearance. Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination and road conditions. Follow that manufacturer’s instructions. To help avoid damage to your vehicle, drive slowly, readjust or remove the device if it’s contacting your vehicle, and don’t spin your wheels.
Don’t use any of these unless this manual says you can. In many uses, these will damage your vehicle: D D D D Alcohol Laundry Soap Bleach Reducing Agents Cleaning the Inside of Your Vehicle D Carefully scrape off any excess stain. D Use a clean cloth or sponge, and change to a clean area often. A soft brush may be used if stains are stubborn. D If a ring forms on fabric after spot cleaning, clean the entire area immediately or it will set.
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 you 2. If a stain remains, follow the Multi-Purpose Interior Cleaner instructions described earlier. 3.
Care of Safety Belts Keep belts clean and dry. CAUTION: Do not bleach or dye safety belts. If you do, it may severely weaken them. In a crash, they might not be able to provide adequate protection. Clean safety belts only with mild soap and lukewarm water. Cleaning Glass Surfaces Cleaning the Outside of the Windshield and Wiper Blades If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax, sap or other material may be on the blade or windshield.
Cleaning the Outside of Your Vehicle Cleaning Exterior Lamps/Lenses The paint finish on your vehicle provides beauty, depth of color, gloss retention and durability. Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses. Follow instructions under “Washing Your Vehicle.” Washing Your Vehicle The best way to preserve your vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water.
Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage your vehicle’s finish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non-abrasive cleaners that are marked safe for painted surfaces to remove foreign matter. Exterior painted surfaces are subject to aging, weather and chemical fallout that can take their toll over a period of years.
Finish Damage Chemical Paint Spotting Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare metal will corrode quickly and may develop into a major repair expense. 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) Service Parts Identification Label You’ll find this label on the inside of 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. You can see it if you look through the windshield from outside your vehicle.
Headlamps Fuses and Circuit Breakers The headlamp wiring is protected by an internal circuit breaker. An electrical overload will cause the lamps to go on and off, or in some cases to remain off. If this happens, have your headlamp wiring checked right away. The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links. This greatly reduces the chance of fires caused by electrical problems.
Instrument Panel Fuse Block The fuse block access door is on the driver’s side edge of the instrument panel. Pull off the cover to access the fuse block. You can remove fuses with a fuse extractor which is mounted to the fuse block access door. To remove fuses if you don’t have a fuse extractor, hold the end of the fuse between your thumb and index finger and pull straight out. You may have spare fuses located behind the fuse block access door. These can be used to replace a bad fuse.

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 Short Trip/City Definition Follow the Short Trip/City Scheduled Maintenance if any one of these conditions is true for your vehicle: D Most trips are less than 5 to 10 miles (8 to 16 km). This is particularly important when outside temperatures are below freezing. D Most trips include extensive idling (such as frequent driving in stop-and-go traffic). D You operate your vehicle in dusty areas or off-road frequently. D You frequently tow a trailer.
Scheduled Maintenance Short Trip/City Intervals Every 30,000 Miles (50 000 km): Rear Axle Fluid Change with Extreme Overload, Trailer Towing or High Speed Use. Fuel Filter Replacement. Every 50,000 Miles (83 000 km): Automatic Transmission Service. Every 60,000 Miles (100 000 km): Engine Accessory Drive Belt Inspection. If Equipped: Exhaust Gas Recirculation System Inspection. Gasoline Engine Only: Evaporative Control System Inspection.
Scheduled Maintenance Long Trip/Highway Definition Follow this scheduled maintenance only if none of the conditions from the Short Trip/City Scheduled Maintenance are true. Do not use this schedule if the vehicle is used for trailer towing, driven in a dusty area or used off paved roads. Use the Short Trip/City schedule for these conditions. Driving a vehicle with a fully warmed engine under highway conditions causes engine oil to break down slower.
Scheduled Maintenance Long Trip/Highway Intervals Every 50,000 Miles (83 000 km): Automatic Transmission Service. Every 60,000 Miles (100 000 km): Engine Accessory Drive Belt Inspection. If Equipped: Exhaust Gas Recirculation System Inspection. Gasoline Engine Only: Evaporative Control System Inspection. Diesel Engine Only: Crankcase Depression Regulator Valve (CDRV) System Check.

The Courtesy Transportation program is offered to retail purchase/lease customers in conjunction with the Bumper-to-Bumper coverage provided by the New Vehicle Limited Warranty.
Courtesy Rental Vehicle When your vehicle is unavailable due to overnight warranty repairs, your dealer may arrange to provide you with a courtesy rental vehicle or reimburse you for a rental vehicle you obtained, at actual cost, up to a maximum of $30.00 per day supported by receipts. This requires that you sign and complete a rental agreement and meet state, local and rental vehicle provider requirements. Requirements vary and may include minimum age requirements, insurance coverage, credit card, etc.
REPORTING SAFETY DEFECTS TO THE UNITED STATES GOVERNMENT If you believe that your vehicle has a defect which could cause a crash or could cause injury or death, you should immediately inform the National Highway Traffic Safety Administration (NHTSA), in addition to notifying General Motors. If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign.
