2000 Chevrolet Silverado Owners Manual

a drive gear, two-wheel high (2H) or four-wheel high (4H) or four-wheel low (4L) -- not in NEUTRAL (N). See “Shifting Into PARK (P)” in the Index. If you’re pulling a trailer, see “Towing a Trailer” in the Index.

2-21

yellowblue

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. Also, use NEUTRAL (N) when your vehicle is being towed.

CAUTION:

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.

NOTICE:

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: D Going less than about 35 mph (56 km/h), push your

accelerator pedal about halfway down.

D Going about 35 mph (56 km/h) or more, push the

accelerator all the way down.

You’ll shift down to the next gear and have more power. DRIVE (D) can be used when towing a trailer, carrying a heavy load, driving on steep hills or for off-road driving. You may want to shift the transmission to THIRD (3) or, if necessary, a lower gear selection if the transmission shifts too often. THIRD (3): This position is also used for normal driving, however it offers more power and lower fuel economy than DRIVE (D). SECOND (2): This position gives you more power but lower fuel economy. You can use SECOND (2) on hills. It can help control your speed as you go down steep mountain roads, but then you would also want to use your brakes off and on. If you manually select SECOND (2) in a light duty automatic transmission, the transmission will drive in second gear. You may use this feature for reducing the speed of the rear wheels when you are trying to start your vehicle from a stop on slippery road surfaces.

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.

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.

On cold days, approximately 32_F (0_C) or colder, your transmission is designed to shift differently until the engine reaches normal operating temperature. This is intended to improve heater performance.

Tow/Haul Mode Selector Switch (Automatic Transmission)

Manual Transmission Operation 5-Speed (VORTEC 6000 V8 Engine)

Here’s how to operate your transmission.

yellowblue

Your vehicle is equipped with a tow/haul mode. The selector switch is located on the end of the column shift lever. You can use this feature to assist when towing or hauling a heavy load. See “Tow/Haul Mode” in the Index for more information.

2-24

FIRST (1) is intended only for heavy loads or trailer towing and is not recommended for normal driving. During the first 500 miles (805 km) of vehicle use, start your vehicle moving in FIRST (1). This allows clutch components to break-in properly. 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.

yellowblue

NEUTRAL (N): Use this position when you start or idle your engine. REVERSE (R): To back up, first press down the clutch pedal. Wait for the vehicle to stop moving and then, shift into REVERSE (R). Let up on the clutch pedal slowly while pressing the accelerator pedal.

NOTICE:

Shift to REVERSE (R) only after your vehicle is stopped. Shifting to REVERSE (R) while your vehicle is moving could damage your transmission.

Also, use REVERSE (R), along with the parking brake, when turning off your engine and parking your vehicle.

SECOND (2): Press the clutch pedal and shift into SECOND (2). Then, slowly let up on the clutch pedal as you press the accelerator pedal. You can shift into SECOND (2) when you’re going less than 20 mph (32 km/h). If you’ve come to a complete stop and it’s hard to shift into SECOND (2), put the shift lever into NEUTRAL (N) and let up on the clutch. Press the clutch pedal back down. Then shift into SECOND (2). If you try to downshift into SECOND (2) at excessive vehicle speeds, the shift lever will not move into the SECOND (2) position until the vehicle speed is reduced. THIRD (3): Press the clutch pedal and shift into THIRD (3). Then, slowly let up on the clutch pedal as you press the accelerator pedal. FOURTH (4) and FIFTH (5): Shift into the higher forward gears the same way you do for THIRD (3). Slowly let up on the clutch pedal as you press the accelerator pedal. To stop, let up on the accelerator pedal and press the brake pedal. Just before the vehicle stops, press the clutch pedal and the brake pedal, and shift to NEUTRAL (N).

2-25

5-Speed (VORTEC 4300 V6 and 4800 V8 Engines) Here’s how to operate your transmission: 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. You can shift into FIRST (1) when you’re going less than 20 mph (32 km/h). If you’ve come to a complete stop and it’s hard to shift into FIRST (1), put the shift lever into NEUTRAL (N) and let up on the clutch. Press the clutch pedal back down. Then shift into FIRST (1). SECOND (2): Press the clutch pedal as you let up on the accelerator pedal and shift into SECOND (2). Then, slowly let up on the clutch pedal as you press the accelerator pedal. THIRD (3), FOURTH (4) and FIFTH (5): Shift into THIRD (3), FOURTH (4) and FIFTH (5) the same way you do for SECOND (2). Slowly let up on the clutch pedal as you press the accelerator pedal.

To stop, let up on the accelerator pedal and press the brake pedal. Just before the vehicle stops, press the clutch pedal and the brake pedal, and shift to NEUTRAL (N). NEUTRAL (N): Use this position when you start or idle your engine. REVERSE (R): To back up, first press down the clutch pedal. Wait for the vehicle to stop moving and then, shift into REVERSE (R). Let up on the clutch pedal slowly while pressing the accelerator pedal.

NOTICE:

Shift to REVERSE (R) only after your vehicle is stopped. Shifting to REVERSE (R) while your vehicle is moving could damage your transmission.

Also, use REVERSE (R), along with the parking brake, when turning off your engine and parking your vehicle.

2-26

Shift Speeds

Shift Light

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 engine speed drops below 600 RPM, or if the engine is not running smoothly, you should downshift to the next lower gear.

yellowblue

If you have a manual transmission, you may have a SHIFT light. This light will show you when to shift to the next higher gear for best fuel economy.

When this light comes on, you can shift to the next higher gear if weather, road and traffic conditions allow. For the best fuel economy, accelerate slowly and shift when the light comes on. While you accelerate, it is normal for the light to go on and off if you quickly change the position of the accelerator. If your vehicle has four-wheel drive and is equipped with a manual transmission, disregard the SHIFT light when the transfer case is in 4-Wheel Low. Ignore the SHIFT light when you downshift.

2-27

Four-Wheel Drive (If Equipped) If your vehicle has four-wheel drive, you can send your engine’s driving power to all four wheels for extra traction. To get the most satisfaction out of four-wheel drive, you must be familiar with its operation. Read the part that follows before using four-wheel drive. See the appropriate text for the transfer case in your vehicle.

NOTICE:

Driving in the 4-WHEEL HIGH (4H) or 4-WHEEL LOW (4L) positions for a long time on dry or wet pavement could shorten the life of your vehicle’s drivetrain.

Front Axle Locking Feature The front axle locks and unlocks automatically when you shift the transfer case. Some delay for the axle to lock or unlock is normal.

2-28

Manual Transfer Case (If Equipped)

yellowblue

The transfer case shift lever is on the floor to the right of the driver. Use this lever to shift into and out of four-wheel drive.

The 4WD indicator will light up when you shift into four-wheel drive and the front axle engages.

Some delay between shifting and the indicator’s lighting is normal.

yellowblue

CAUTION:

Shifting the transfer case to NEUTRAL (N) can cause your vehicle to roll even if the transmission is in PARK (P), or if you have a manual transmission, even if you are in gear. You or someone else could be seriously injured. Be sure to set the parking brake before placing the transfer case in NEUTRAL (N). See “Parking Brake” in the Index.

NEUTRAL (N): Shift to this setting only when your vehicle needs to be towed. The ignition switch must be in the RUN position in order to shift the lever into NEUTRAL (N). See “Recreational Vehicle Towing” or “Towing your Vehicle” in the Index. 4-Wheel Low (4L): This setting also engages your front axle and delivers extra torque. You may never need 4LO. It sends maximum power to all four wheels. You might choose 4LO if you are driving off-road in deep sand, deep mud, deep snow and climbing or descending steep hills.

2-29

An indicator on the bezel near the lever shows you the transfer case settings: 2-Wheel High (2H): This setting is used for driving in most street and highway situations. Your front axle is not engaged in two-wheel drive. This setting also provides the best fuel economy. 4-Wheel High (4H): Use 4HI when you need extra traction, such as on snowy or icy roads or in most off-road situations. This setting also engages your front axle to help drive your vehicle. This is the best setting to use when plowing snow.

yellowblue

Automatic Transfer Case (If Equipped)

The transfer case switches are located to the left of the instrument panel cluster.

Use these switches to shift into and out of four-wheel drive.

You can shift from 2-Wheel High (2H) to 4-Wheel High (4H) or from 4-Wheel High (4H) to 2-Wheel High (2H) while the vehicle is moving. Your front axle will engage faster if you take your foot off of the accelerator for a couple of seconds after you shift. In extremely cold weather, it may be necessary to stop or slow the vehicle to shift into 4-Wheel High (4H). To shift into or out of 4-Wheel Low (4L) or NEUTRAL (N): 1. Slow the vehicle to a roll, about 1 to 3 mph

(2 to 5 km/h) and shift an automatic transmission into NEUTRAL (N), or with a manual transmission, press the clutch pedal.

2. Shift the transfer case shift lever in one

continuous motion.

Don’t pause in NEUTRAL (N) as you shift the transfer case into 4-Wheel Low (4L), or your gears could clash. Remember that driving in 4-Wheel High (4H) or 4-Wheel Low (4L) may reduce fuel economy. Also, driving in four-wheel drive on dry pavement could cause your tires to wear faster and make your transfer case harder to shift and run noisier.

2-30

yellowblue

4HI: Use 4HI when you need extra traction, such as on snowy or icy roads or in most off-road situations. This setting also engages your front axle to help drive your vehicle. This is the best setting to use when plowing snow. 4LO: This setting also engages your front axle and delivers extra torque. You may never need 4LO. It sends maximum power to all four wheels. You might choose 4LO if you are driving off-road in deep sand, deep mud, deep snow and climbing or descending steep hills.

CAUTION:

Shifting the transfer case to NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P). You or someone else could be seriously injured. Be sure to set the parking brake before placing the transfer case in NEUTRAL. See “Parking Brake” in the Index.

NEUTRAL: Shift the vehicle’s transfer case to NEUTRAL only when towing your vehicle. See “Recreational Vehicle Towing” or “Towing Your Vehicle” in the Index for more information.

2-31

You can choose among four driving settings: 2HI: This setting is used for driving in most street and highway situations. Your front axle is not engaged in two-wheel drive. This setting also provides the best fuel economy. AUTO 4WD: This setting is ideal for use when road conditions are variable. When driving your vehicle in AUTO 4WD, the front axle is engaged, but the vehicle’s power is sent only to the rear wheels. When the vehicle senses a loss of traction, the system will automatically engage four-wheel drive. Driving in this mode results in slightly lower fuel economy than 2HI.

yellowblue

Indicator lights in the switches show 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 to your dealer for service. An indicator light will flash while shifting the transfer case. It will remain illuminated when the shift is complete. If for some reason the transfer case cannot make a requested shift, it will return to the last chosen setting. If the SERVICE 4WD light stays on, you should take your vehicle to your dealer for service. See “Service 4WD” in the Index for further information.

Shifting to 4HI or AUTO 4WD Press and release the 4HI or AUTO 4WD switch. This can be done at any speed (except when shifting from 4LO), and the indicator light will flash while shifting. It will remain illuminated when the shift is completed.

Shifting to 2HI Press and release the 2HI switch. This can be done at any speed (except when shifting from 4LO).

2-32

Shifting to 4LO To shift to 4LO, the ignition must be in RUN and the vehicle must be stopped or moving less than 3 mph (4.8 km/h) 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 km/h). Press and release the 4LO switch. You must wait for the 4LO indicator light to stop flashing and remain illuminated before shifting your transmission in 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 less than 3 mph (4.8 km/h) and the transmission is in NEUTRAL (N). After 30 seconds the transfer case will return to the setting last chosen.

Shifting Out of 4LO To shift from 4LO to 4HI, AUTO 4WD or 2HI your vehicle must be stopped or moving less than 3 mph (4.8 km/h) with the transmission in NEUTRAL (N) and the ignition in RUN. The preferred method for shifting out of 4LO is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Press and release the 4HI, AUTO 4WD or 2HI switch. You must wait for the 4HI, AUTO 4WD or 2HI indicator light to stop flashing and remain illuminated before shifting your transmission into gear.

yellowblue

If the 4HI, AUTO 4WD or 2HI switch is pressed when your vehicle is in gear and/or moving, the 4HI, AUTO 4WD or 2HI indicator light will flash for 30 seconds but will not complete the shift unless your vehicle is moving less than 3 mph (4.8 km/h) and the transmission is in NEUTRAL (N).

Shifting to NEUTRAL To shift the transfer case to NEUTRAL, first make sure the vehicle is parked so that it will not roll: 1. Set the parking brake. 2. Start the vehicle or turn the ignition to RUN. 3. Connect the vehicle to the towing vehicle. 4. Put the transmission in NEUTRAL (N). 5. Shift the transfer case to 2HI. 6. Simultaneously press and hold the 2HI and 4LO buttons for 10 seconds. The red NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete.

7. Shift the transmission to REVERSE (R) for one

second, then shift the transmission to DRIVE (D) for one second.

8. Turn the ignition to OFF. 9. Place the transmission shift lever in PARK (P). 10. Release the parking brake prior to towing.

Shifting Out of NEUTRAL To shift out of NEUTRAL: 1. Set the parking brake and apply the regular

brake pedal.

2. Shift the transmission to NEUTRAL (N) and turn the

ignition to RUN with the engine off.

3. Press the button for the desired transfer case shift

position (2HI, 4HI, AUTO 4WD or 4LO).

4. After the transfer case has shifted out of NEUTRAL

the red light will go out.

5. You may start the engine and shift the transmission

to the desired position.

2-33

Parking Brake To set the parking brake, hold the regular brake pedal down with your right foot. Push down the parking brake pedal with your left foot. If the ignition is on, the brake system warning light will flash. A chime will activate when the parking brake is applied and the vehicle is moved at least 3 mph (5 km/h) for at least three seconds.

yellowblue

To release the parking brake, hold the regular brake pedal down. Pull the bottom edge of the lever, located above the parking brake pedal, marked BRAKE RELEASE, to release the parking brake. If the ignition is on when the parking brake is released, the brake system warning light will go off.

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 are parking on any hill, see “Towing a Trailer” in the Index. That section shows what to do first to keep the trailer from moving.

2-34

Shifting Into PARK (P) (Automatic Transmission Only)

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. With four-wheel drive if your transfer case is in NEUTRAL (N), your vehicle will be free to roll, even if your shift lever is in PARK (P). So, be sure the transfer case is in a drive gear -- not in NEUTRAL (N). If you’re pulling a trailer, see “Towing a Trailer” in the Index.

yellowblue

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

set the parking brake.

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

like this:

D Pull the shift lever toward you.

2-35

yellowblue

Leaving Your Vehicle With the Engine Running (Automatic Transmission Only)

CAUTION:

It can be dangerous to leave your vehicle with the engine running. Your vehicle could move suddenly if the shift lever is not fully in PARK (P) with the parking brake firmly set. If you have four-wheel drive with a manual transfer case shift lever and your transfer case is in NEUTRAL (N), your vehicle will be free to roll, even if your shift lever is in PARK (P). So be sure the transfer case is in a drive gear -- not in NEUTRAL (N). 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.

D Move the lever up as far as it will go.

3. Be sure the transfer case is in a drive gear -- not in

NEUTRAL (N).

4. Turn the ignition key to LOCK. 5. Remove the key and take it with you. If you can leave your vehicle with the ignition key in your hand, your vehicle is in PARK (P).

2-36

yellowblue

If you have to leave your vehicle with the engine running, be sure your vehicle is in PARK (P) and the parking brake is firmly set before you leave it. After you move the shift lever into PARK (P), hold the regular brake pedal down. Then, see if you can move the shift lever away from PARK (P) without first pulling it toward you. If you can, it means that the shift lever wasn’t fully locked into PARK (P). 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. 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) (Automatic Transmission Only) Your vehicle has an automatic transmission shift lock control system. You have to fully apply your regular brakes before you can shift from PARK (P) when the ignition is in RUN. See “Automatic Transmission” in the Index. If you cannot shift out of PARK (P), ease pressure on the shift lever and push the shift lever all the way up into PARK (P) as you maintain brake application. Then, move the shift lever into the gear you want. If you ever hold the brake pedal down but still can’t shift out of PARK (P), try this: 1. Turn the key to the OFF ignition position. 2. Apply and hold the brake until the end of Step 4. 3. Shift the vehicle to NEUTRAL (N). 4. Start the vehicle and then shift to the drive gear

you want.

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

2-37

Parking Your Vehicle (Manual Transmission Models Only)

Parking Over Things That Burn

yellowblue

CAUTION:

Shifting the transfer case to NEUTRAL (N) can cause your vehicle to roll even if the manual transmission is in gear. You or someone else could be seriously injured. Be sure to set the parking brake before placing the transfer case in NEUTRAL (N). See “Parking Brake” in the Index.

Before you get out of your vehicle, put your manual transmission in REVERSE (R), turn off the engine, and firmly apply the parking brake. If you are parking on a hill, or if you are pulling a trailer, see “Towing a Trailer” in the Index.

2-38

CAUTION:

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

Engine Exhaust

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. D Your vehicle or exhaust system had been

modified improperly.

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

blow out any CO; and

D Have your vehicle fixed immediately.

yellowblue

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

CAUTION:

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

2-39

yellowblue

Manual Selectable Ride (If Equipped) The main function of this system is to provide superior ride comfort while trailering or fully loaded, as well as for unloaded driving. This system also helps to provide: D Improved trailering stability D Improved handling response when trailering or

fully loaded

This button is located on the center of the instrument panel near the radio. Press it to activate the selectable ride setting as desired. An indicator light near the button will illuminate whenever the system is active.

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). Four-wheel drive vehicles with the transfer case in NEUTRAL (N) will allow the vehicle to roll, even if your shift lever is in PARK (P). So, be sure the transfer case is in a drive gear -- not in NEUTRAL (N). Always set your parking brake.

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.

2-40

yellowblue

FIRM (Loaded): Press the switch to activate this setting, the indicator light will illuminate. Use this setting to minimize trailer inputs to the vehicle or when the vehicle is fully loaded. This setting is also appropriate for off-road driving. You can select a setting at any time based on road and trailering conditions to provide the best ride and handling. Select a new setting whenever driving conditions change. Locking Rear Axle If your vehicle has this feature, 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.

It is recommended to use this system as follows: D For optimum ride comfort in an unloaded vehicle the

button should be out and the indicator light will not be illuminated. This switch position indicates NORMAL levels of ride control or damping.

D For optimum ride comfort when trailering, fully

loaded, driving off-road, or when personal preferences demand more control the button should be pressed in with the indicator light illuminated. This switch position indicates FIRM levels of ride control or damping.

The following guide can also be used to help determine the best setting. NORMAL: The indicator light will be off when the system is in this setting. Use for normal city and highway driving. Provides a smooth, soft ride when the vehicle is unloaded. FIRM (Unloaded): Press the switch to activate this setting, the indicator light will illuminate. Use this setting when road conditions or personal preference demand more control. Provides more “feel” or response to the road conditions.

Turn Signal/Multifunction Lever

The lever on the left side of the steering column includes your: D Turn Signal and Lane Change Indicator D Headlamp High/Low Beam Changer D Flash-to-Pass D Windshield Wipers D Windshield Washer D Cruise Control (If Equipped) 2-44

yellowblue

Turn Signal and Lane Change Signals The turn signal has two upward (for right) and two downward (for left) positions. These positions allow you to signal a turn or a lane change. To signal a turn, move the lever all the way up or down. When the turn is finished, the lever will return automatically.

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

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. If you move the lever all the way up or down, and the arrow flashes at twice the normal rate, a signal bulb may be burned out and other drivers may not see your turn signal. If a bulb is burned out, replace it to help avoid an accident. If the arrows don’t go on at all when you signal a turn, check for burned-out bulbs and a blown fuse (see “Fuses and Circuit Breakers” in the Index).

yellowblue

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 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 on the instrument panel also will be on.

Flash-To-Pass Feature This feature allows you to use your high-beam headlamps to signal a driver in front of you that you want to pass. It works even if your headlamps are off. To use it, pull the turn signal lever toward you, but not so far that you hear it click. If your headlamps are off or on low-beam, your high-beam headlamps will turn on. They’ll stay on as long as you hold the lever toward you and the high-beam indicator on the instrument panel will come on. Release the lever to turn the high-beam headlamps off.

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.

2-46

yellowblue

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.

CAUTION:

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

Cruise Control

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

If you apply your brakes, or press the clutch pedal (if equipped), the cruise control will disengage.

yellowblue

CAUTION:

D 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.

D 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.

2-47

yellowblue

The CRUISE light on the instrument panel will illuminate when the cruise control is engaged.

Resuming a Set Speed Suppose you set your cruise control at a desired speed and then you apply the brake or press the clutch pedal (if equipped). This, of course, disengages the cruise control. But you don’t need to reset it. Once you’re going about 25 mph (40 km/h) or more, you can move the cruise control switch from ON to R/A briefly. You’ll go right back up to your chosen speed and stay there. If you hold the switch at R/A briefly, 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.

Setting Cruise Control

CAUTION:

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

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.

2-48

Increasing Speed While Using Cruise Control There are two ways to go to a higher speed: D Use the accelerator pedal to get to the higher speed.

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

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.

Reducing Speed While Using Cruise Control D Press and hold the SET button at the end of the lever

until you reach the lower speed you want, then release it.

D To slow down in very small amounts, press the SET button briefly. Each time you do this, you’ll go about 1 mph (1.6 km/h) slower.

Passing Another Vehicle While Using Cruise Control 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.

yellowblue

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: D Step lightly on the brake pedal. D Step lightly on the clutch pedal (if equipped). D 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.

Exterior Lamps

Your parking lamp and headlamp switch is on the driver’s side of your instrument panel. Turn the knob clockwise to the parking lamps symbol to manually turn on: D Parking Lamps D Sidemarker Lamps D Taillamps D License Plate Lamps D Instrument Panel Lights 2-50

yellowblue

Turn the knob clockwise to the master lamps symbol to turn on all the lamps listed as well as the headlamps. Turn the knob all the way counterclockwise to turn off your lamps and put the system in auto 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 a light sensor located on the top of the instrument panel in the defroster grille. Be sure it is not covered, or the system will be on whenever the ignition is on. The system may also turn on your headlamps when driving through a parking garage, heavy overcast weather or a tunnel. This is normal. 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.

yellowblue

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 thumbwheel 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 it easier for 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 come on when: D the ignition is on, D the headlamp switch is in automatic headlamp mode,

D the automatic transmission is not in PARK (P), D the light sensor determines it is daytime and D the parking brake is released. When the DRL are on, only your DRL lamps 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 automatic headlamp system will switch from DRL to the headlamps or the last chosen headlamp setting that was used. When you turn the headlamp switch off, the headlamps will go off, and your DRL lamps will illuminate, provided it is not dark outside. To idle an automatic transmission equipped vehicle with the DRL off, set the parking brake. Shifting the transmission into PARK (P) will also allow you to idle the vehicle with the DRL off. The DRL will stay off until you release the parking brake or shift the transmission out of PARK (P). To idle a manual transmission equipped 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.

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

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. 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.

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 modules, the wiring, the passenger air bag suppression circuit and the crash sensing and 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 vehicle, 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 vehicle or comes on when you are driving, your air bag system may not work properly. Have your vehicle serviced right away.

yellowblue

CAUTION:

If the air bag readiness light stays on after you start your vehicle, it means the air bag system may not be working properly. The air bags in your vehicle may not inflate in a crash, or they could even inflate without a crash. To help avoid injury to yourself or others, have your vehicle serviced right away if the air bag readiness light stays on after you start your vehicle.

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.

2-73

AIR BAG OFF Light When you turn the right front passenger’s air bag off, this light will come on and stay on to remind you that the air bag has been turned off. This light will go off when you turn the air bag back on again. See “AIR BAG OFF Switch” in the Index for more on this, including important safety information.

yellowblue

CAUTION:

If the right front passenger’s air bag is turned off for a person who isn’t in a risk group identified by the national government, that person won’t have the extra protection of an air bag. In a crash, the air bag wouldn’t be able to inflate and help protect the person sitting there. Don’t turn off the passenger’s air bag unless the person sitting there is in a risk group. See “AIR BAG OFF Switch” in the Index for more on this, including important safety information.

2-74

CAUTION:

If the air bag readiness light ever comes on when you have turned off the air bag, it means that something may be wrong with the air bag system. The right front passenger’s air bag could inflate even though the switch is off. If your vehicle is a regular cab pickup and this ever happens, don’t let anyone whom the national government has identified as a member of a passenger air bag risk group sit in the right front passenger’s position (for example, don’t secure a rear-facing child restraint in your vehicle) until you have your vehicle serviced. If your vehicle is an extended cab pickup and this ever happens, don’t let anyone whom the national government has identified as a member of a passenger air bag risk group sit in the right front passenger’s position (for example, don’t secure a rear-facing child restraint in the right front passenger’s seat) until you have your vehicle serviced.

Voltmeter

yellowblue

When your engine is not running, but the ignition is in RUN, this gage shows your battery’s state of charge in DC volts.

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. 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.

yellowblue

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. Shift Light (If Equipped)

This light is used on some models with manual transmissions.

Brake System Warning Light With the ignition on, the brake system warning light will flash when you set the parking brake. The light will flash if the parking brake doesn’t release fully. If you try to drive with the parking brake engaged, a chime will sound when the vehicle speed is greater than 3 mph (5 km/h). 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.

The SHIFT indicator light will help you get the best fuel economy. See “Shift Light” or “Shift Speeds” in the index for more information.

This light should come on briefly when you turn the ignition key to RUN. If it doesn’t come on then, have it fixed so it will be ready to warn you if there’s a problem.

2-76

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.)

CAUTION:

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.

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. 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.

Engine Coolant Temperature Gage

This gage shows the engine coolant temperature.

Transmission Temperature Gage (If Equipped)

If your vehicle has a heavy duty automatic transmission, you will have a transmission temperature gage.

yellowblue

It also provides an indicator of how hard your vehicle is working. During a majority of the operation, the gage will read 210_F (100_C) or less. If you are pulling a load or going up hills, it is normal for the temperature to fluctuate and approach the 250_F (122_C) mark. If the gage reaches the 260_F (125_C) mark, it indicates that the cooling system is working beyond its capacity. The “Problems on the Road,” section of this manual shows what to do. See “Engine Overheating” in the Index.

When your ignition is on, the gage shows the temperature of the transmission fluid. The normal operating range is from 100_F (38_C) to about 265_F (130_C). At approximately 265_F (130_C), the message center will display a TRANS FLUID HOT message and the transmission will enter a transmission protection mode. When the transmission enters the protection mode, you may notice a change in the transmission shifting patterns. The transmission will return to normal shifting patterns when the transmission fluid temperature falls below 260_F (127_C).

2-78

See “Message Center” in the Index for further information. If the transmission fluid reaches temperatures of approximately 275_F (135_C) or greater, the message center will display a TRANS HOT...IDLE ENG warning message. Pull the vehicle off the roadway when it is safe to do so. Set the parking brake, place the transmission in PARK (P) and allow the engine to idle until the transmission temperature falls below 260_F (127_C). If the transmission continues to operate above 265_F (130_C), please contact your nearest dealer or the GM Roadside Assistance Center.

NOTICE:

If you keep driving your vehicle with the transmission temperature gage above the normal operating range, you can damage the transmission. This could lead to costly repairs that may not be covered under your warranty.

yellowblue

The following situations can cause the transmission to operate at higher temperatures: D Towing a trailer D Hot outside air temperatures D Hauling a large or heavy load D Low transmission fluid level D High transmission fluid level D Restricted air flow to the radiator and the auxiliary

transmission oil cooler (if equipped).

A temporary solution to hotter transmission operating temperatures may be to let the transmission cool down. If the transmission is operated at higher temperatures on a frequent basis, see “Scheduled Maintenance” in the Index for the proper transmission maintenance intervals.

Malfunction Indicator Lamp (Service Engine Soon Light)

NOTICE:

Your vehicle is equipped with a computer which monitors operation of the fuel, ignition and emission control systems.

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 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. 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.

2-80

NOTICE:

Modifications made to the engine, transmission, exhaust 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 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.

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: D 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.

D 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.

If the Light Is Flashing The following may prevent more serious damage to your vehicle: D Reducing vehicle speed. D Avoiding hard accelerations. D Avoiding steep uphill grades. D If you are towing a trailer, reduce the amount of

cargo being hauled as soon as it is possible.

yellowblue

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. See “Filling Your Tank” in the Index. 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.

2-81

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 gear, 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.

Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or may begin programs to inspect the emission control equipment on your vehicle. Failure to pass this inspection could prevent you from getting a vehicle registration. Here are some things you need to know in order to help your vehicle pass an inspection: Your vehicle will not pass this inspection if the SERVICE ENGINE SOON light is on or not working properly. 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. If you have done this and your vehicle still does not pass the inspection for lack of OBD system readiness, see your dealer or qualified service center to prepare the vehicle for inspection.

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).

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.

yellowblue

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. See “Check Eng Oil Pressure” and “Engine Oil” in the Index.

NOTICE:

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