Changes or modifications to this system by other than an authorized service facility could void authorization to use this equipment. This system has a range of about 3 feet (1 m) up to 30 feet (9 m). At times you may notice a decrease in range. This is normal for any remote keyless entry system. If the transmitter does not work or if you have to stand closer to your vehicle for the transmitter to work, try this: 0 Check to determine if battery replacement or

resynchronization is necessary. See the instructions that follow. Check the distance. You may be too far from your vehicle. You may need to stand closer during rainy or snowy weather. Check the location. Other vehicles or otqects may be blocking the signal. Take a few steps to the left or right, hold the transmitter higher, and try again. If you’re still having trouble, see your dealer or a qualified technician for service.

Matching Transmitter(s) To Your Vehicle Each remote keyless entry transmitter is coded to prevent another transmitter from unlocking your vehicle. If a transmitter is lost or stolen, a replacement can be purchased through your dealer. Remember to bring any remaining transmitters with you when you go to your dealer. When the dealer matches the replacement transmitter to your vehicle, any remaining transmitters must also be matched. Once your dealer has coded the new transmitter, the lost transmitter will not unlock your vehicle. Each vehicle can have only four transmitters matched to it.

Operation UNLOCK: Pressing this button once will unlock the driver’s door. The parking lamps will flash and the interior lights will come on. Pressing this button once also unlocks the rear liftglass. Pressing UNLOCK again within three seconds will cause the remaining doors to unlock. The parking lamps will flash and the interior lights will come on. LOCK: Pressing this button once will lock all of the doors. Press LOCK again within three seconds and the horn will chirp. REAR: Press this button twice within three seconds to release the liftglass. The parking lamps will flash and the interior lights will come on. The transmission must be PARK (P) or NEUTRAL (N). Remote Panic Alarm When the button with the horn symbol on the key transmitter is pressed, the horn will sound and the headlamps and taillamps will flash for up to 30 seconds. This can be turned off by pressing the horn button again, waiting for 30 seconds, or starting the vehicle.

Battery Replacement 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. Static from your body transferred to these surfaces may damage the transmitter.

2-8

To replace the battery in the keyless entry transrnitter:

1. Insert a dime in the slot between the covers of the

transmitter housing near the key ring hole. Remove the bottom by twisting the dime.

2. Remove and replace the battery with a three volt

CR2032 or equivalent battery, positive (+) side up.

3. Align the covers and snap them together. 4. Resynchronize the transmitter. 5. Check the operation of the transmitter.

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. To resynchronize your transmitter, stand close to your vehicle and press and hold the LOCK and UNLOCK buttons on the transmitter at the same time for seven seconds. The door locks should cycle to confirm synchronization. If the locks do not cycle. see your dealer for service.

LiftgateLiftglass

or

It can be dangerous to drive with the liftgate liftglass open because carbon monoxide (CO) gas can come into your vehicle. You can’t see or smell CO. It can cause unconsciousness and even death. If‘ you must drive with the liftgate or liftglass open or if electrical wiring or other cable connections must pass through the seal between the body and the liftgate or liftglass: Make sure all windows are shut. Turn the fan on your heating or cooling system to its highest speed with the setting on any airflow selection except RECIRCULATION. That will force outside air into your vehicle. See “Comfort Controls” in the Index. If you have air outlets on or under the instrument panel, open them all the way.

See “Engine Exhaust” in the Index.

2-9

Liftgate Release To release the liftgate or liftglass, you may use the Keyless Entry System described earlier. The liftglass can be opened if the driver’s door is unlocked.

To open the liftglass only, press the button and pull up on the handle.

Remote Liftglass Release 1 This button on the

passenger’s side of the steering column allows you to release the liftglass from inside the vehicle.

To open the entire liftgate, lift the handle located in the center of the door.

Your shift lever must be in PARK (P) or NEUTRAL (N) for the release to work. Theft Vehicle theft is big business, especially in some cities. Although your vehicle has a number of theft-deterrent features, we know that nothing we put on it can make it impossible to steal. However, there are ways you can help.

2-10

Key in the Ignition If you leave your vehicle with the keys inside, it’s an easy target for joy riders or professional thieves -- so don’t do it. When you park your vehicle and open the driver’s door, you’ll hear a chime reminding you to remove your key from the ignition and take it with you. Always do this. Your steering wheel will be locked, and so will your ignition and transmission. And remember to lock the doors. Parking at Night Park in a lighted spot, close all windows and lock your vehicle. Remember to keep your valuables out of sight. Put them in a storage area, or take them with you. Parking Lots If you park in a lot where someone will be watching your vehicle, it’s best to lock it up and take your keys. But what if you have to leave your ignition key? What if you have to leave something valuable in your vehicle?

Put your valuables in a storage area, like your glove box. Lock all the doors except the driver’s.

Content Theft-Deterrent

SECURITY

Your vehicle is equipped with a Content Theft-Deterrent alarm system.

With this system, the SECURITY light will flash as you open the door (if your ignition is off). This light reminds you to activate the theft-deterrent system. Here’s how to do it: 1. Open the door. 2. Lock the door with the power door lock switch or the

remote keyless entry transmitter. The SECURITY light should come on and stay on.

3. Close all doors. The SECURITY light should go off

after approximately 30 seconds. The alarm is not armed until the SECURITY light goes off.

If a door is opened without the key or the remote keyless entry transmitter, the alarm will go off. Your vehicle’s high-beam headlamps will flash and the horn will sound for 30 seconds, then will turn off to save the battery power. 2-11

Remember, the theft-deterrent system won‘t activate if you lock the doors with a key or use the manual door lock. It activates only if you use a power door lock switch with the door open, or with the remote keyless entry transmitter. You should also remember that you can start your vehicle with the correct ignition key if’ the alarm has been set off. Here’s how to avoid setting off the alarm by accident:

If you don’t want to activate the theft-deterrent system, the vehicle should be locked with the door key after the doors are closed. Always unlock a door with a key, or use the remote keyless entry transmitter. Unlocking a door any other way will set off the alarm.

If you set off the alarm by accident, unlock any door with the key. You can also turn off the alarm by pressing UNLOCK on the remote keyless entry transmitter. The alarm won’t stop if you try to unlock a door any other way. Testing the Alarm The alarm can be tested by following these steps: I . From inside the vehicle, lower the driver‘s window

and open the driver’s door.

Activate the system by locking the doors with the power door lock switch while the door is open, or with the remote keyless entry transmitter. Get out of the vehicle, close the door and wait for the SECURITY light to go out. Then reach in through the window, unlock the door with the manual door lock and open the door. This should set off the alarm.

4.

see “Fuses and Circuit Breakers” in the Index.

If the alarm does not sound when it should but the vehicle’s high-beam headlamps flash, check to see if the horn works. The horn fuse may be blown. To replace the f ~ ~ s e , If the alarm does not sound or the vehicle’s high-beam headlamps do not flash, the vehicle should be serviced by an authorized service center. Passlock’ Your vehicle is equipped with the Passlock theft-deterrent system. Passlock is a passive theft-deterrent system. The system is armed once the key is removed from the ignition. Passlock enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used, fuel is disabled.

2-12

During normal operation, the SECURITY light will go off after the engine is started. If the engine stalls and the SECURITY light flashes, wait about 10 minutes until the light stops flashing before trying to restart the engine. Remember to release the key from the START position as soon as the engine starts. If the engine does not start after three (3) tries, the vehicle needs service. If you are driving and the SECURITY light comes on, you will be able to restart the engine if you turn the engine off. However, your Passlock system is not working properly and must be serviced by your dealer. Your vehicle is not protected by Passlock at this time. You may also want to check the fuse (see ”FLIS~S and Circuit Breakers” in the Index). See your dealer for service. If the SECURITY light comes on while the engine is running. a problem has been detected and the system may need service. See your dealer for service. In an emergency, call the GMC Roadside Assistance Center a t 1 -800-GMC-8782 ( i n Canada, call 1-800-268-6800).

New Vehicle “Break-In”

NOTICE:

~~~

Your vehicle doesn’t need an elaborate “break-in.” But it will perform better in the long run if you follow these guidelines:

Keep your speed at 55 mph (88 kmh) or Don’t drive at any one speed -- fast or less for the first 500 miles (805 km). slow -- for the first 500 miles (805 km). Don’t make full-throttle starts. Avoid making hard stops for the first 200 miles (322 km) or so. During this time your new brake linings aren’t yet broken in. Hard stops with new linings can mean premature wear and earlier replacement. Follow this breaking-in guideline every time you get new brake linings. Don’t tow a trailer during break-in. See “Towing a Trailer” in the Index for more information.

2-13

I NOTICE:

Don’t operate accessories in the ACCESSORY position for long periods of time. Prolonged operation of accessories in the ACCESSORY position could drain your battery and prevent you from starting your vehicle.

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. Use OFF if you must have your vehicle in motion while the engine is off (for example, if your vehicle is being towed). RUN (D): This is the position for driving. START (E): This position starts your engine.

Ignition Positions Use the key to turn the ignition switch to five different positions.

ACCESSORY (A): This position lets you use things like the radio and the windshield wipers when the engine is off. Push in the key and turn it toward you. Your steering wheel will remain locked, just as it was before you inserted the key.

2-14

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. If none of this works, then your vehicle needs service.

Retained Accessory Power Your vehicle is equipped with a Retained Accessory Power (RAP) feature which will allow certain features on your vehicle to continue to work up to 20 minutes after the ignition key is turned to OFF. Your radio, power windows, sunroof and overhead console will work when the ignition key is in RUN or ACCESSORY. Once the key is turned from RUN to OFF, these features will continue to work for up to 20 minutes or until a door is opened.

Starting Your Engine Move your shift lever to PARK (P) or NEUTRAL (N). Your engine won’t start in any other position -- that’s a safety feature. To restart when you’re already moving, use NEUTRAL (N) only.

I NOTICE:

Don’t try to shift to PARK (P) if your vehicle is moving. If you do, you could damage the transmission. Shift to PARK (P) only when your vehicle is stopped.

1. Without pushing the accelerator pedal, turn your

ignition key to START. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm.

2-15

I NOTICE:

Holding your key in START for longer than 15 seconds at a time will cause your battery to be drained much sooner. And the excessive heat can damage your starter motor.

2. If it doesn’t start right away, hold your key in

START. If it doesn’t start in 10 seconds, push the accelerator pedal all the way down for five more seconds, unless it starts sooner.

3. If your engine still won’t start (or starts but then

stops), wait 15 seconds and start over. When the engine starts, let go of the key and the accelerator pedal.

NOTICE:

Your engine is designed to work with the electronics in your vehicle. If you add electrical parts or accessories, you could change the way the engine operates. Before adding electrical equipment, check with your dealer. If you don’t, your engine might not perform properly. If you ever have to have your vehicle towed, see the part of this manual that tells how to do it without damaging your vehicle. See “Towing Your Vehicle” in the Index.

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.

2-16

4. Before starting the engine, be sure to unplug and

store the cord as it was before to keep it away from moving engine parts. If you don’t, it could be damaged.

How long should you keep the coolant heater plugged in? The answer depends on the outside temperature, the kind of oil you have, and some other things. Instead of trying to list everything here, we ask that you contact your dealer in the area where you’ll be parking your vehicle. The dealer can give you the best advice for that particular area.

To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord. The

cord is located on the driver’s side of the engine compartment, behind the underhood fuse block. 3. Plug it into a normal, grounded 110-volt AC outlet.

% CAUTION:

Plugging the cord into an ungrounded outlet could cause an electrical shock. Also, the wrong kind of extension cord could overheat and cause a fire. You could be seriously injured. Plug the cord into a properly grounded three-prong 110-volt AC outlet. If the cord won’t reach, use a heavy-duty three-prong extension cord rated for at least 15 amps.

2-17

Automi ic Transmission Operation There are several different positions for your shift lever. PARK (P): This locks your rear wheels. It’s the best position to use when you start your engine because your vehicle can’t move easily.

It is dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll. Don’t leave your vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To 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). See “Shifting Into PARK (P)” in the Index. If you’re pulling a trailer, see “Towing a Trailer” in the Index.

2-18

Ensure the shift lever is fully in PARK (P) before starting the engine. Your vehicle has a Brake-Transmission Shift Interlock (BTSI). You have to fully apply your regular brakes before you can shift from PARK (P) when the ignition key is in RUN. If you cannot shift out of PARK (P), ease pressure on the shift lever -- push the shift lever all the way into PARK (P) (press the button in on the console shift lever) as you maintain brake application. Then move the shift lever into the gear you wish. See “Shifting Out of PARK (P)” in the Index. REVERSE (R): Use this gear to back up.

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 when you’re already moving, use NEUTRAL (N) only.

Shifting out of PARK (P) or NEUTRAL (N) while your engine is “racing” (running at high speed) is dangerous. Unless your foot is firmly on the brake pedal, your vehicle could move very rapidly. You could lose control and hit people or objects. Don’t shift out of PARK (P) or NEUTRAL (N) while your engine is racing.

I NOTICE:

m l

Damage to your transmission caused by shifting out of PARK (P) or NEUTRAL (N) with the engine racing isn’t covered by your warranty.

DRIVE (D): This position is for normal driving. If you need more power for passing, and you’re: 0 Going less than about 35 mph (55 krdh), push your

accelerator pedal about halfway down. Going about 35 mph (55 krdh) or more, push the accelerator all the way down.

You’ll shift down to the next gear and have more power. DRIVE (D) should not be used when towing a trailer, carrying a heavy load, driving on steep hills, or for off-road driving. Select THIRD (3) when operating the vehicle under any of these conditions. THIRD (3): This position is also used for normal driving, however it offers more power and lower fuel economy than DRIVE (D). You should use THIRD (3) when towing a trailer, carrying a heavy load, driving on steep hills or winding roads or for off-road driving. SECOND (2): This position gives you more power but lower fuel economy than THIRD (3). You can use SECOND (2) on hills. It can help control your speed as you go down steep mountain roads, but then you would also want to use your brakes off and on. You can also use SECOND (2) for starting your vehicle from a stop on slippery road surfaces.

2-19

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 (1) until the vehicle is going slowly enough.

NOTICE:

If your rear wheels can’t rotate, don’t try to drive. This might happen if you were stuck in very deep sand or mud or were up against a solid object. You could damage your transmission. Also, if you stop when going uphill, don’t hold your vehicle there with only the accelerator pedal. This could overheat and damage the transmission. Use your brakes or shift into PARK (P) to hold your vehicle in position on a hill.

2-20

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 BRAKE RELEASE lever. It is located on the bottom of the driver’s side of the instrument panel.

NOTICE:

Driving with the parking brake on can cause your rear brakes to overheat. You may have to replace them, and you could also damage other parts of your vehicle.

If you are towing a trailer and you must park on a hill, see “Towing a Trailer” in the Index. That section shows what to do first to keep the trailer from moving.

Shifting Into PARK (P) L!h C A U T L .:

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. Always put the shift lever fully in PARK (P) with the parking brake firmly set. If you’re pulling a trailer, see “Towing a Trailer” in the Index.

1. Hold the brake pedal down with your right foot and

set the parking brake.

2-21

2. Move the shift lever into PARK (P) position

like this:

Leaving Your Vehicle With the Engine Running

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.

If you have to leave your vehicle with the engine running, be sure your vehicle is in PARK (P) and your parking brake is firmly set before you leave it. After you’ve moved the shift lever into PARK (P), hold the regular brake pedal down. Then, see if you can move the shift lever away from PARK (P) without pressing the button on the shift lever. If you can, it means that the shift lever wasn’t fully locked into PARK (P).

Hold in the button on the lever. Push the lever all the way toward the front of the vehicle.

3. Turn the ignition key to LOCK, 4. Remove the key and take it with you. If you can leave your vehicle with the key, your vehicle is in PARK (P).

2-22

Torque Lock 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. When you are ready to drive, move the shift lever out of PARK (P) before you release the parking brake. If torque lock does occur, you may need to have another vehicle push yours a little uphill to take some of the pressure from the parking pawl in the transmission, so you can pull the shift lever out of PARK (P).

Shifting Out of Park (P) Your vehicle has a Brake-Transmission Shift Interlock (BTSI). You have to fully apply your regular brake before you can shift from PARK (P) when the ignition is in RUN. See “Automatic Transmission Operation” in the Index. If you cannot shift out of PARK (P), ease pressure on the shift lever -- push the shift lever all the way into PARK (P) as you maintain brake application. Then move the shift lever into the gear you want. You must press the shift lever button on the console shift lever. If you ever hold the brake pedal down but still can’t shift out of PARK (P), try this: 1. Turn the key to OFF. 2. Apply and hold the brake until the end of Step 4. 3. Shift to NEUTRAL (N). 4. Start the vehicle and then shift to the drive gear

you want.

5. Have the vehicle fixed as soon as you can.

P

-ing Over

nqs That Burn

Engine Exhaust

Engine exhaust can kill. It contains the gas carbon monoxide (CO), which you can't see or smell. It can cause unconsciousness and death. You might have exhaust coming in if:

Your exhaust system sounds strange or different. Your vehicle gets rusty underneath.

0 Your vehicle was damaged in a collision. Your vehicle was damaged when driving over high points on the road or over road debris.

0 Repairs weren't done correctly. 0 Your vehicle or exhaust system had been

modified improperly.

Things that can burn could touch hot exhaust parts under your vehicle and ignite. Don't park over papers, leaves, dry grass or other things that can burn.

2-24

If you ever suspect exhaust is coming into your vehicle: 0 Drive it only with all the windows down to

blow out any CO; and

0 Have your vehicle fixed immediately.

Running Your Engine While You’re Parked It’s better not to park with the engine running. But if ever you have to, here are some things to know.

A CAUTION:

Idling the engine with the air system control off could allow dangerous exhaust into your vehicle (see the earlier Caution under “Engine Exhaust”). Also, idling in a closed-in place can let deadly carbon monoxide (CO) into your vehicle even if this can happen is a garage. Exhaust -- with the fan switch is at the highest setting. One place CO -- can come in easily. NEVER park in a

garage with the engine running. Another closed-in place can be a blizzard. (See L6BlizzardSS in the

Index.)

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).

Follow the proper steps to be sure your vehicle won’t move. See “Shifting Into PARK (P)” in the Index. If you’re pulling a trailer, see “Towing a Trailer” in the Index.

2-25

Locking Rear Axle Your locking rear axle can give you additional traction on snow, mud, ice, sand or gravel. It works like a standard axle most of the time, but when one of the rear wheels has no traction and the other does, this feature will allow the wheel with traction to move the vehicle. Four-wheel Drive Because your vehicle has four-wheel drive, you can send your engine’s driving power to all four wheels for extra traction. To shift out of two-wheel drive and into four-wheel drive, push the 4HI or 4LO button on the transfer case switch. You should use 2HI for most normal driving conditions.

Driving in the 4HI or 4LO positions for a long time on dry or wet pavement could shorten the life of your vehicle’s drivetrain.

2-26

Electronic Transfer Case

The transfer case switches are above the radio controls.

Use these switches to shift into and out of four-wheel drive. You can choose among three driving settings: 2HI: This setting is for driving in most street and highway situations. Your front axle is not engaged in two-wheel drive. 4HI: This setting engages your front axle to help drive your vehicle. Use 4HI when you need extra traction, such as on snowy or icy roads, or in most off-road situations.

4LO: This setting also engages your front axle to give you extra traction. You may never need 4LO. It sends the maximum power to all four wheels. You might choose 4LO if you were driving off-road in sand, mud or deep snow and climbing or descending steep hills. Indicator lights in the switches show you which setting you are in. The indicator lights will come on briefly when you turn on the ignition and one will stay on. If the lights do not come on, you should take your vehicle in for service. An indicator light will flash while shifting. It will remain illuminated when the shift is completed.

Shifting from 2HI to 4HI Press and release the 4HI switch. This can be done at any speed, and the front axle will lock automatically.

Shifting from 4HI to 2HI Press and release the 2HI switch. This can be done at any speed, and the front axle will unlock automatically.

Shifting from 2HI or 4HI to 4LO To shift from 2HI or 4HI to 4L0, the vehicle must be stopped or moving less than 3 mph (4.8 kmh) with the transmission in NEUTRAL (N). The preferred method for shifting into 4LO is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 kmh). Press and release the 4LO switch. You must wait for the 4LO indicator light to stop flashing and remain illuminated before shifting your transmission into gear. If the 4LO switch is pressed when your vehicle is in gear and/or moving, the 4LO indicator light will flash for 30 seconds and not complete the shift unless your vehicle is moving slower than 3 mph (4.8 k d h ) and the transmission is in NEUTRAL (N). If your transfer case does not shift into 4L0, your transmission indicator switch may require adjustment. With your transmission in NEUTRAL (N), press and release the 4LO switch. While the 4LO indicator light is flashing, shift your transmission into PARK (P). Wait until the 4LO indicator light remains illuminated before shifting your transmission into gear. This will get you into 4L0, but you should take your vehicle in for service to restore normal operation.

2-27

Shifting from 4LO to 4HI or 2HI To shift from 4LO to 4H1 or 2H1, your vehicle must be stopped or moving less than 3 mph (4.8 k d h ) with the transmission in NEUTRAL (N). The preferred method for shifting out of 4LO is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 k d h ) . Press and release the 4HI switch. You must wait for the 4H1 indicator light to stop flashing and remain illuminated before shifting your transmission into gear. If the 4HI switch is pressed when your vehicle is in gear and/or moving, the 4HI indicator light will flash for 30 seconds but not complete the shift unless the vehicle is moving slower than 3 mph (4.8 kmh) and the transmission is in NEUTRAL (N).

If your transfer case does not shift into 4H1, your transmission indicator switch may require adjustment. With your transmission in NEUTRAL (N), press and release the 4HI switch. While the 4HI indicator light is flashing, shift your transmission into PARK (P). Wait until the 4HI indicator light remains illuminated before shifting your transmission into gear. This will get you into 4H1, but you should take your vehicle in for service to restore normal operation. Windows Power Windows The controls for the power windows are on each of the side doors. The switches control the windows when the ignition is on or when Retained Accessory Power (RAP) is present. (See “Retained Accessory Power” in the Index.) The driver’s door has a switch to control the passenger windows as well.

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.

I An arrow on the instrument panel will flash in the direction of the turn or lane change.

To signal a lane change, just raise or lower the lever until the arrow starts to flash. Hold it there until you complete your lane change. The lever will return by itself when you release it. The signal indicator will flash even if a turn signal bulb is burned out. Check the front and rear turn signal lamps regularly to make sure they are working.

If a bulb is burned out, replace it to help avoid an accident. If the arrows don’t go on at all when you signal a turn, check the fuse (see “Fuses and Circuit Breakers” in the Index) and for burned-out bulbs.

Turn Signal On Chime If your turn signal is left on for more than 3/4 of a mile (1.2 km), a chime will sound at each flash of the turn signal. To turn off the chime, move the turn signal lever to the off position. Headlamp High/Low Beam Changer To change the headlamps from low beam to high or high to low, pull the multifunction lever all the way toward you. Then release it.

When the high beams are on, this indicator light on the instrument panel will also be on.

Windshield Wipers

You control the windshield wipers by turning the band with the wiper symbol on it. For a single wiping cycle, turn the band to MIST. Hold it there until the wipers start, then let go. The wipers will stop after one wipe. If you want more wipes, hold the band on MIST longer. You can set the wiper speed for a long or short delay between wipes. This can be very useful in light rain or snow. Turn the band to choose the delay time. The closer to LO, the shorter the delay. 2-32

For steady wiping at low speed, turn the band away from you to the LO position. For high-speed wiping, turn the band further, to HI. To stop the wipers, move the band to the OFF position. Be sure to clear ice and snow from the wiper blades before using them. If they’re frozen to the windshield, carefully loosen or thaw them. If your blades do become worn or damaged, get new blades or blade inserts. Windshield Washer There is a paddle marked with the windshield washer symbol at the top of the multifunction lever. To spray washer fluid on the windshield, push the paddle. The wipers will clear the window and then either stop or return to your preset speed.

In freezing weather, don’t use your washer until the windshield is warmed. Otherwise the washer fluid can form ice on the windshield, blocking your vision.

Cruise Control

With cruise control, you can maintain a speed of about 25 mph (40 km/h) or more without keeping your foot on the accelerator. This can really help on long trips. Cruise control does not work at speeds below about 25 mph (40 kmh).

If you apply your brakes, the cruise control will disengage.

2-33

To turn the rear wiper on, slide the switch to either LO or HI. To turn the wiper off, slide the switch to OFF. To wash the window, press the wash button located on the switch. The switch must be in either LO or HI. The rear window washer uses the same fluid bottle as the windshield washer. However, the rear window washer will run out of fluid before the windshield washer. If you can wash your windshield but not your rear window, check your fluid level.

CAUTION:

1. Move the cruise control switch to ON. 2. Get up to the speed you want.

3. Press in the SET button

at the end of the lever and release it.

4. Take your foot off the accelerator pedal.

Cruise control can be dangerous where you 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.

I ,A CAUTION:

If you leave your cruise control switch on when you’re not using cruise, you might hit a button and go into cruise when you don’t want to. You could be startled and even lose control. Keep the cruise control switch off until you want to use it.

2-34

Resuming a Set Speed Suppose you set your cruise control at and then you apply the brake. This, of course, disengages the cruise control. But you don’t need to reset it.

a desired speed

Once you’re going about 25 mph (40 km/h) or more, you can move the cruise control switch from ON to R/A for about a half a second.

You’ll go right back up to your chosen speed and stay there. If you hold the switch at FUA longer than half a second, the vehicle will keep going faster until you release the switch or apply the brake. So unless you want to go faster, don’t hold the switch at R/A.

Increasing Speed While Using Cruise Control There are two ways to go to a higher speed:

Use the accelerator pedal to get to the higher speed. Press the SET button at the end of the lever, then release the button and the accelerator pedal. You’ll now cruise at the higher speed.

0 Move the cruise switch from ON to FUA. 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 for less than half a second. Each time you do this, your vehicle will go about 1 mph (1.6 km/h) faster.

Reducing Speed While Using Cruise Control

Press and hold the SET button at the end of the lever until you reach the lower speed you want, then release it. To slow down in very small amounts, press the SET button for less than half a second. Each time you do this, you’ll go 1 mph (1.6 km/h) slower.

2-35

Passing Another Vehicle While Using Cruise Control Exterior Lamps Use the accelerator pedal to increase your speed. When you take your foot off the pedal, your vehicle will slow down to the cruise control speed you set earlier.

Using Cruise Control on Hills 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 want to step on the accelerator pedal to maintain your speed. When going downhill, you may have to brake or shift to a lower gear to keep your speed down. Of course, applying the brake takes you out of cruise control. Many drivers find this to be too much trouble and don’t use cruise control on steep hills.

Ending Cruise Control There are two ways to turn off the cruise control:

Step lightly on the brake pedal. Move the cruise control switch to OFF.

Erasing Speed Memory When you turn off the cruise control or the ignition, your cruise control set speed memory is erased.

Your parking lamp and headlamp switch is on the driver’s side of your instrument panel. Rotate the knob to the right to the parking lamps symbol to manually turn on:

Parking Lamps Sidemarker Lamps Taillamps License Plate Lamps Instrument Panel Lights

Rotate the knob to the right to the master lamps symbol to turn on all the lamps listed as well as the headlamps. Rotate the knob all the way to the left to turn off your lamps and put the system in automatic headlamp mode. Automatic Headlamp System When it is dark enough outside, your automatic headlamp system will turn on your headlamps at the normal brightness along with other lamps such as the taillamps, sidemarker, parking lamps and the instrument panel lights. The radio lights will also be dim. Your vehicle is equipped with High Intensity Discharge (€€ID) headlamps. Your headlamps come on at lower intensity and gradually increase to full brightness. Your vehicle is equipped with a light sensor on the top so of the instrument panel under the radio speaker grille, be sure it is not covered, which will cause the system to be on whenever the ignition is on. The system may also turn on your headlamps when driving through a parking garage, heavy overcast weather, a tunnel or fueling your vehicle in a low-light area. This is normal. There is a delay in the transition between the daytime and nighttime operation of the Daytime Running Lamps (DRL) and the automatic headlamp systems so that

driving under bridges or bright overhead street lights does not affect the system. The DRL and automatic headlamp system will only be affected when the light sensor sees a change in lighting lasting longer than the delay. To idle your vehicle with the automatic headlamp system off, set the parking brake while the ignition is off. Then start your vehicle. The automatic headlamp system will stay off until you release the parking brake. As with any vehicle, you should turn on the regular headlamp system when you need it. Lamps On Reminder A reminder chime will sound when your headlamps or parking lamps are manually turned on and your ignition is in OFF, LOCK or ACCESSORY. To disable the chime, rotate the thumb wheel all the way down. In the automatic mode, the headlamps turn off once the ignition key is in OFF, Daytime Running Lamps Daytime Running Lamps (DRL) can make others to see the front of your vehicle during the day. DRL can be helpful in many different driving conditions, but they can be especially helpful in the short periods after dawn and before sunset.

The DRL system will make your high-beam headlamps come on at reduced brightness when:

Fog Lamps

the ignition is on, the headlamp switch is in automatic headlamp mode and the parking brake is released.

When the DRL are on, only your high-beam headlamps will be on. The taillamps, sidemarker and other lamps won’t be on. The instrument panel won’t be lit up either. When it begins to get dark, the high-beam headlamps will automatically switch from DRL to the regular low-beam headlamps. When you turn the headlamp switch off, the regular low-beam headlamps will go off, and your high-beam headlamps will change to the reduced brightness of DRL provided it is not dark outside. To idle your vehicle with the DRL off, set the parking brake. The DRL will stay off until you release the parking brake. As with any vehicle, you should turn on the regular headlamp system when you need it.

2-38

Use your fog lamps for better vision in foggy or misty conditions. Your low-beam headlamps or your parking lamps must be on for your fog lamps to work. The fog lamp switch is on the instrument panel under the lamps switch. Press the switch to turn the fog lamps on. Press the switch again to turn them off. A light will glow in the switch when the fog lamps are on. Remember, fog lamps alone will not give off as much light as your headlamps. Never use your fog lamps in the dark without turning on your headlamps. The fog lamps will go off whenever your high-beam headlamps come on. When the high beams go off, the fog lamps will come on again.

Interior Lamps Brightness Control Rotate the thumbwheel next to the headlamp switch up to make your instrument panel lights brighter. Turn the switch all the way up to turn on the interior lamps. Exit Lighting With exit lighting, the interior lamps will come on when you remove the key from the ignition. These lights will stay on for a short period of time and then will go out. Illuminated Entry Your vehicle is equipped with an illuminated entry feature. When the doors are opened, the dome lamps will come on if the DOME OVERRIDE button is out. When all the doors are closed, or the front door handles are lifted and released, the lamps will stay on for a short period of time and will then go out. If the dome lamp button is pressed in, the lamps will go out immediately.

Front Reading Lamp? Press the button near each lamp on the overhead console to turn the reading lamps on and off. The lamps can be swiveled to point in the desired direction. If you have the mini console, press the lens on each lamp to turn it on or off. Dome Lamps The dome lamps will come on when you open the doors. You can also turn the dome lamps on by rotating the thumbwheel, located next to the parking/headlamps knob, all the way LIP. In this position, the dome lamps will remain on whether the doors are opened or closed.

2-39

You can use the DOME OVERRIDE button, located below the parking/headlamp knob, to set the dome lamps to come on automatically when the doors are opened, or to remain off. To turn the lamps off, press the Mirror button once into the “in” position. With the button in this position, the dome lamps will remain off when the doors are open. To return the lamps to automatic operation, press the button again and return it to the “out” position. With the button in this position, the dome lamps will come on when you open the door. This will not override the illuminated entry feature. Battery Run-Down Protection This feature shuts off the dome, courtesy, vanity, reading, glove box and underhood lamps if they are left on for more than 20 minutes when the ignition is off. This will keep your battery from running down. If the battery run-down protection shuts off the interior lamps, it may be necessary to do one of the following to return to normal operation: 0 Shut off all lamps and close all doors, or

Turn the ignition key to RUN.

Mirrors Electrochromic Daymight Inside Rearview

This mirror automatically changes to reduce glare from headlamps behind you. A photocell on the back of the mirror senses when it is becoming dark outside. Another photocell built into the mirror surface senses when headlamps are behind you. At night, when the glare is too high, the mirror will gradually darken to reduce glare (this change may take a few seconds). The mirror will return to its clear daytime state when the glare is reduced. The vehicle will also return to its clear daytime state when the vehicle is put into REVERSE (R).

The control is located on the driver’s door armrest.

Press the OFF AUTO button at the base of the mirror to turn on the automatic feature. The button has an indicator light to show it is on. Press the OFF AUTO button to turn the automatic feature off.

Time Delay The automatic mirror has a time delay feature which prevents unnecessary switching from the night back to the day position. This delay prevents rapid changing of the mirror as you drive under lights and through traffic.

Move the upper control to the left or right to choose the mirror, then press the arrows on the control pad to adjust the mirror.

Cleaning the Photocells Use a cotton swab and glass cleaner to clean the photocells when necessary.

Press the button near each lamp to turn the reading lamps on and off.

The lamps can also be swiveled to point in the desired direction.

Driver Information System This system displays the outside air temperature, compass direction and trip information in the overhead console. USMET The USMET (United Statedmetric) button allows you to switch the display between the English and metric system.

MODE: The MODE button can be used to toggle between three modes of operation: OFF, COMP/TEMP and TRIP. OFF: This button turns the system off. COMP/TEMP: The display provides the outside temperature and one of eight compass readings to indicate the direction the vehicle is facing. Before you turn on the ignition and move the vehicle, the temperature indicated will be the last outside temperature recorded with the ignition on. If the outside temperature is 37°F (3°C) or lower, the display will toggle between the word ICE and the current temperature every eight seconds. This is a warning to the driver that road conditions may be icy, and that appropriate precautions should be taken. The compass is self-calibrating, so it does not need to be manually set. However, if C (Calibration) is displayed, the compass will need to be calibrated. You may also place the compass in a noncalibrated mode by pressing and holding the MODE and USMET buttons simultaneously while in the COMPREMP mode. After about 10 seconds, the compass will display C and you can release the buttons. Drive the vehicle in a complete 360" circle three times at a speed of less than 5 mph (8 km/h), and the compass will function normally. Once the calibration is complete, the display will return to a compass reading.

3. After five seconds, the compass will acknowledge the variation mode by displaying the current zone number, When it does, release both buttons.

4. Press US/MET until your zone number appears on

the display.

5. Press MODE to enter your zone number. Your

variance is now set and the display will return to the COMP/TEMP mode.

TRIP: Once in the TRIP mode, pressing the MODE button will step you through the following TRIP functions: 0 AVG ECON: The average fuel economy since the

last reset is displayed. INST ECON: Instantaneous fuel economy for the last second of driving is displayed. RANGE: The display indicates the estimated distance that can be travelled with the remaining fuel in the tank, based on the fuel economy for the last few hours of driving. FUEL USED: The fuel used since the last reset is displayed. AVG SPEED: The average speed since the last reset is displayed.

Variance is the difference between magnetic north and geographic north. In some areas, the difference between the two can be great enough to cause false compass readings. If this happens, follow these instructions to set the variance for your particular location: 1. Find your location on the zone map earlier in this

section. Note your zone number.

2. Press and hold both the MODE and the USMET

buttons in the COMP/TEMP mode.

Use GM accessory racks that are compatible with your luggage carrier for transporting sports equipment. These are available through your GM dealer. You can adjust the crossrails to handle loads of various sizes. Just loosen the slider knobs at each end of the crossrail and move them to where you want them. Make sure both sides of the crossrails are even, then tighten the slider knobs. Be sure the cargo is properly loaded. Follow these guidelines:

Carrying small, heavy loads on the roof is not recommended. Tie the load to the tie down (at either end of the crossrails). When loading cargo directly on the roof panel, use the crossrails to keep the from shifting. If you need to carry long items, move the crossrails as far apart as possible. Tie the load to the tie downs provided. Also tie the load to the bumpers. Do not tie the load so tightly that the crossrails or side rails are damaged.

load

If you try to carry something on top of your vehicle that is longer or wider than the luggage carrier -- like paneling, plywood, a mattress, and so forth -- the wind can catch it as you drive along. This can cause you to lose control. What you are carrying could be violently torn off, and this could cause you or other drivers to have a collision, and of course damage your vehicle. You may be able to carry something like this inside. But, never carry something longer or wider than the luggage carrier on top of your vehicle.

The luggage carrier has slats, side rails and crossrails attached to the roof to secure cargo. The adjustable tie downs, at either end of the crossrails, should be used to secure loads to the luggage carrier.

2-48

NOTICE:

Loading cargo that weighs more than 200 Ibs. (91 kg) on the luggage carrier may damage your vehicle. When you carry large things, never let them hang over the rear or the sides of your vehicle. When loading cargo on the roof panel, be sure it rests on the slats and does not scratch or damage the vehicle. Put the cargo against the side rails and fasten it securely to the luggage carrier. Put the main weight as far forward as you can and move the rear crossrail forward as far as possible to keep the load from shifting.

Don’t exceed the maximum vehicle capacity when loading your vehicle. For more information on vehicle capacity and loading, see “Loading Your Vehicle“ in the Index. To prevent damage or loss of cargo as you’re driving, check now and then to make sure the luggage carrier and cargo are still securely fastened.

Speedometer and Odometer Your speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (kdh). Your odometer shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). You may wonder what happens if your vehicle needs a new odometer installed. If the new one can be set to the mileage total of the old odometer, then it must be. But if it can’t, then it’s set at zero, and a label must be put on the driver’s door to show the old mileage reading when the new odometer was installed.

Trip Odometer The trip odometer can tell you how far your vehicle has been driven since you last set the trip odometer to zero. To view the trip odometer, press the button near the readout. To reset the trip odometer, hold the button until it resets. Tachometer The tachometer displays the engine speed in revolutions per minute (rpm).

Each tachometer has a different limit depending on the powertrain in your vehicle. The tachometer has three areas: normal operating range, red warning range and red danger range. The normal operating range shows your engine speed during normal driving conditions. For example, when the needle points to 2, it means the engine is running at 2,000 revolutions per minute (rpm). The tachometer needle will vary all the time that the engine is running. The shaded red warning range tells you that your engine speed is reaching its upper limits. Don’t drive very long with the tachometer in the red warning range. Lift your foot off the accelerator pedal. The solid red danger range tells you that your engine speed is at its upper limits. You should immediately shift to a higher gear, or lift your foot off the accelerator pedal.

NOTICE:

Do not operate the engine with the tachometer in the red range, or engine damage will occur.

ing 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. As you will see in the details on the next few pages, some warning lights come on briefly when you start the engine just to let you know they’re working. If you are familiar with this section, you should not be alarmed when this happens. Gages can indicate when there may be or is a problem with one of your vehicle’s functions. Often gages and warning lights work together to let you know when there’s a problem with your vehicle.

When one of the warning lights comes on and stays on when you are driving, or when one of the gages shows there may be a problem, check the section that tells you what to do about it. Please follow this manual’s advice. Waiting to do repairs can be costly -- and even dangerous. So please get to know your warning lights and gages. They’re a big help. Safety Belt Reminder Light When the key is turned to RUN or START, a chime will come on for about eight seconds to remind people to fasten their safety belts, unless the driver’s safety belt is already buckled.

The safety belt light will also come on and stay on for about 20 seconds, then it will flash for about 55 seconds.

If the driver’s belt is already buckled, neither the chime nor the light will come on.

2-62

Air Bag Readiness Light There is an air bag readiness light on the instrument panel, which shows the air bag symbol. The system checks the air bag’s electrical system for malfunctions. The light tells you if there is an electrical problem. The system check includes the air bag sensors, the air bag module, the wiring and the diagnostic module. For more information on the air bag system, see “Air Bag” in the Index.

This light will come on when you start your engine, and it will flash for a few seconds. Then the light should go out. This means the system is ready.

If the air bag readiness light stays on after you start the engine or comes on when you are driving, your air bag system may not work properly. Have your vehicle serviced right away. The air bag readiness light should flash for a few seconds when you turn the ignition key to RUN. If the light doesn’t come on then, have it fixed so it will be ready to warn you if there is a problem.

Charging System Indicator Light

The charging system light will come on briefly when you turn on the ignition, but

’ the engine is not running,

as a check to show you it is working.

It should go out once the engine is running. If it stays on, or comes on while you are driving, you may have a problem with the charging system. It could indicate that you have problems with a generator drive belt, or another electrical problem. Have it checked right away. Driving while this light is on could drain your battery. If you must drive a short distance with the light on, be certain to turn off all your accessories, such as the radio and air conditioner.

2-63

Voltmeter Gage

I When your engine is not

running, but the ignition is on (in RUN), this gage shows your battery’s state of charge in DC volts.

Readings in the low warning zone may occur when a large number of electrical accessories are operating in the vehicle and the engine is left at an idle for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power. 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.

When the engine is running, the gage shows the condition of the charging system. Readings between the low and high warning zones indicate the normal operating range.

2-64

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. If it stays on after your parking brake is fully released, it means you have a brake problem. Your vehicle’s hydraulic brake system is divided into two parts. If one part isn’t working, the other part can still work and stop you. For good braking, though, you need both parts working well. If the warning light comes on, there could be a brake problem. Have your brake system inspected right away.

it fixed so it will be ready to warn you if there’s a problem.

If the light comes on while you are driving, pull off the road and stop carefully. You may notice that the pedal is harder to push. Or, the pedal may go closer to the floor. It may take longer to stop. If the light is still on, have the vehicle towed for service. (See “Towing Your Vehicle” in the Index.)

Your brake system may not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to an accident. If the light is still on after you’ve pulled off the road and stopped carefully, have the vehicle towed for service.

2-65

Anti-Lock Brake System Warning Light

Engine Coolant Temperature Gage

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.

This gage shows the engine coolant temperature. If the gage pointer moves into the red area, your engine is too hot!

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. See “Brake System Warning Light” earlier in this section. The anti-lock brake system warning light should come on briefly when you turn the ignition key to RUN. If the light doesn’t come on then, have it fixed so it will be ready to warn you if there is a problem.

It means that your engine coolant has overheated. If you have been operating your vehicle under normal driving conditions, you should pull off the road, stop your vehicle and turn off the engine as soon as possible. The “Problems on the Road” section of this manual shows you what to do. See “Engine Overheating” in the Index.

Malfunction Indicator Lamp (Service Engine Soon Light)

NOTICE:

SERVICE ENGINE SOON

United States

Canada

Your vehicle is equipped with a computer which monitors operation of the fuel, ignition and emission control systems. This system is called OBD I1 (On-Board Diagnostics-Second Gene.ration) and is intended to assure that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment. The SERVICE ENGINE SOON light comes on to indicate that there is a problem and service is required. Malfunctions often will be indicated by the system before any problem is apparent. This may prevent more serious damage to your vehicle. This system is also designed to assist your service technician in correctly diagnosing any malfunction.

If you keep driving your vehicle with this light on, after a while, your emission controls may not work as well, your fuel economy may not be as good and your engine may not run as smoothly. This could lead to costly repairs that may not be covered by your warranty.

This light should come on, as a check to show you it is working, when the ignition is on and the engine is not running. If the light doesn’t come on, have it repaired. This light will also come on during a malfunction in one of two ways:

Light Flashing -- A misfire condition has been detected. A misfire increases vehicle emissions and may damage the emission control system on your vehicle. Dealer or qualified service center diagnosis and service may be required. Light On Steady -- An emission control system malfunction has been detected on your vehicle. Dealer or qualified service center diagnosis and service may be required.

2-67

If the Light Is Flashing The following may prevent more serious damage to your vehicle:

Reducing vehicle speed. Avoiding hard accelerations. Avoiding steep uphill grades. If you are towing a trailer, reduce the amount of cargo being hauled as soon as it is possible.

If the light stops flashing and remains on steady, see “If the Light Is On Steady” following. If the light continues to flash, when it is safe to do so, stop the vehicle. Find a safe place to park your vehicle. Turn the key off, wait at least 10 seconds and restart the engine. If the light remains on steady, see “If the Light Is On Steady” following. If the light is still flashing, follow the previous steps, and drive the vehicle to your dealer or qualified service center for service.

If the Light Is On Steady You may be able to correct the emission system malfunction by considering the following: Did you recently put fuel into your vehicle? If so, reinstall the fuel cap, making sure to fully install the cap. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap will allow fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off. Did you just drive through a deep puddle of water? If so, your electrical system may be wet. The condition will usually be corrected when the electrical system dries out. A few driving trips should turn the light off.

2-68

Have you recently changed brands of fuel? If so, be sure to fuel your vehicle with quality fuel (see "Fuel" in the Index). Poor fuel quality will cause your engine not to run as efficiently as designed. You may notice this as stalling after start-up, stalling when you put the vehicle into g a r , misfiring, hesitation on acceleration or stumbling on acceleration. (These conditions may go away once the engine is warmed up.) This will be detected by the system and cause the light to turn on. 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 none of the above steps have made the light turn off, have your dealer or qualified service center check the vehicle. Your dealer has the proper test equipment and diagnostic tools to fix any mechanical or electrical problems that may have developed.

Engine Oil Pressure Gage

The oil pressure gage shows the engine oil pressure in psi (pounds per square inch) when the engine is running.

Canadian vehicles indicate pressure in kPa (kilopascals). 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 other problems causing low oil pressure.

2-69

A CAUTION:

Don’t keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches fire. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced.

I NOTICE:

Damage to your engine from neglected oil problems can be costly and is not covered by your warranty.
