Passenger Sensing System

If your rearview mirror has one of the indicators pictured in the following illustrations, your vehicle has a passenger sensing system. The indicator will be visible when you turn your ignition key to RUN or START. The words ON and OFF or the symbol for on and off, will be visible on the rearview mirror during the system check. When the system check is complete, either the word ON or the word OFF, or the symbol for on or the symbol for off will be visible. See Passenger Air Bag Status lndicator on page 3-36. If your rearview mirror does not have either of the indicators pictured below, then your vehicle does not have the passenger sensing system.

Passenger Air Bag Status Indicator - United States

Passenger Air Bag

Status

Indicator - Canada

The passenger sensing system will turn off the right front passenger’s frontal air bag under certain conditions. The driver’s air bag and the side air bags are not part of the passenger sensing system. In addition to the passenger sensing system, your vehicle also has an air bag off switch located on the instrument panel as required by the government. The passenger sensing system works with sensors that are part of the right front passenger’s seat and safety belt. The sensors are designed to detect the presence of a properly seated occupant and determine if the passenger’s frontal air bag should be enabled (may inflate) or not.

e

The passenger sensing system is designed to turn off the ‘

right front passenger’s frontal air bag if:

the right front passenger seat is unoccupied the system determines that an infant is present in a rear-facing infant seat the system determines that a small child is present in a forward-facing child restraint the system determines that a small child is present in a booster seat, a right front passenger takes hidher weight off of the seat for a period of time the right front passenger seat is occupied by a smaller person, such as a child who has outgrown child restraints or a very small person the air bag off switch is in the off position or if there is a critical problem with the air bag system or the passenger sensing system

When the passenger’s frontal air bag has been turned off either by the passenger sensing system or by the air bag off switch, the off indicator will light and stay lit to remind you that the air bag is off.

The passenger sensing system is designed to turn off the passenger’s frontal air bag when a rear facing infant seat, a forward-facing child restraint or a booster seat is detected. If the child restraint has been installed and the on indicator is lit, turn the vehicle off, remove the child restraint from the vehicle and reinstall the restraint following the child restraint manufacturer’s directions and refer to Securing a Child Restraint in the Right Front Seat Position on page 1-54 of this manual. If after reinstalling the child restraint and restarting the vehicle, the on indicator is still lit, secure the child in the child restraint in a rear seat position in the vehicle and check with your dealer. The passenger sensing system is designed to enable (may inflate) the right front passenger’s frontal air bag anytime the system senses that a person of adult size is sitting properly in the right front passenger’s seat. When the passenger sensing system has allowed the air bag to be enabled, the on indicator will light and stay lit to remind you that the air bag is active. If a person of adult-size is sitting in the right front passenger’s seat, but the off indicator is lit, it could be because that person isn’t sitting properly in the seat or the air bag off switch is in the off position.

1-75

If this happens and the switch is in the proper position, turn the vehicle off and ask the person to place the seatback in the full upright position, then sit upright in the seat, centered on the seat cushion, with the person’s legs comfortably extended. Restart the vehicle and have the person remain in this position for about two minutes. This will allow the system to detect that person and then enable the passenger’s air bag.

If the air bag readiness light in the instrument panel cluster ever comes on and stays on, it means that something may be wrong with the air bag system. If this ever happens, have the vehicle serviced promptly, because an adult-size person sitting in the right front passenger’s seat may not have the protection of the frontal air bag. See “Air Bag Readiness Light” in the Index for more on this, including important safety information.

Aftermarket equipment, such as seat covers, can affect how well the passenger sensing system operates. You may want to consider not using seat covers or other aftermarket equipment if your vehicle has the passenger sensing system.

1-76

Stowing of articles under th, gassenger’s seat or between the passenger’s seat cushion and seatback may interfere with the proper operation of the passenger sensing system.

Servicing Your Air Bag-Equipped Vehicle Air bags affect how your vehicle should be serviced. There are parts of the air bag system in several places around your vehicle. You don’t want the system to inflate while someone is working on your vehicle. Your dealer and the service manual have information about servicing your vehicle and the air bag system. To purchase a service manual, see Service Publications Ordering Information on page 7- IO.

FOI -,- -0 1 m..-_rte after the igni n key is turned off and the battery is disconnected, an air bag can still inflate during improper service. You can be injured if you are close to an air bag when it inflates. Avoid yellow connectors. They are probably part of the air bag system. Be sure to follow proper service procedures, and make sure the person performing work for you is qualified to do so.

The air bag system does not need regular maintenance.

properly under a wide range of conditions, including snow plowing with vehicles equipped with the optional Snow Plow Prep Package (RPO VYU). But don’t change or defeat the snow plow’s ”tripping mechanism.” If you do, it can damage your snow plow and your vehicle, and it may cause an air bag inflation.

Adding Equipment to Your Air Bag-Equipped Vehicle

Q: Is there anything I might add to the front of the

vehicle that could keep the air bags from working properly?

A: Yes. If you add things that change your vehicle’s frame, bumper system, front end sheet metal or height, they may keep the air bag system from working properly. Also, the air bag system may not work properly if you relocate any of the air bag sensors. If you have any questions about this, you should contact Customer Assistance before you modify your vehicle. The phone numbers and addresses for Customer Assistance are in Step Two of the Customer Satisfaction Procedure in this manual. See ”Customer Satisfaction Procedure” in the Index.

Restraint System Check

Checking Your Restraint Systems Now and then, make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired.

Torn or frayed safety belts may not protect you in a crash. They can rip apart under impact forces. If a belt is torn or frayed, get a new one right away. Also look for any opened or broken air bag covers, and have them repaired or replaced. (The air bag system does not need regular maintenance.)

Replacing Restraint System Parts Ac*er a Crash

IS in I may

A crash can damage the restraint system your vehicle. A damaged restraint systen not properly protect the person using it, resulting in serious injury or even death crash. To help make sure your restraint systems are working properly after a crash, have them inspected and any necessary replacements made as soon as possible.

in a

If you’ve had a crash, do you need new belts or LATCH system parts? After a very minor collision, nothing may be necessary. But if the belts were stretched, as they would be if worn during a more severe crash, then you need new parts. If the LATCH system was being used during a more severe crash, you may need new LATCH system parts. If belts are cut or damaged, replace them. Collision damage also may mean you will need to have LATCH system, safety belt or seat parts repaired or replaced. New parts and repairs may be necessary even if the belt or LATCH system wasn’t being used at the time of the collision. If an air bag inflates, you’ll need to replace air bag system parts. See the part on the air bag system earlier in this section.

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:

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 objects may be blocking the signal. Take a few steps to the left or right, hold the transmitter higher, and try again. Check to determine if battery replacement or resynchronization is necessary. See “Battery Replacement” and “Resynchronization” under Remote Keyless Entry System Operation on page 2-5. If you are still having trouble, see your dealer or a qualified technician for service.

Remote Keyless Entry System Operation If your vehicle has this feature, you can lock and unlock your doors from about 3 feet (1 rn) up to 30 feet (9 m) away using the remote keyless entry transmitter supplied with your vehicle. UNLOCK: Pressing this button once will unlock the driver’s door. The parking lamps will flash and the interior lights will come on. The ground illumination lamps will come on. 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. Wait one second, then press LOCK again and the horn will chirp. Operating the keyless entry transmitter may interact with the theft-deterrent system. See Content Theft-Deterrent on page 2- 18. Remote Alarm When the panic button with the horn symbol on the keyless entry 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 panic button again, waiting for 30 seconds, or starting the vehicle.

Unlocked doors can be dangerous.

Passengers - especially children - can easily open the doors and fall out of a moving vehicle. When a door is locked, the handle won’t open it. You increase the chance of being thrown out of the vehicle in a crash if the doors aren’t locked. So, wear safety belts properly and lock the doors whenever you drive. Young children who get into unlocked vehicles may be unable to get out. A child can be overcome by extreme heat and can suffer permanent injuries or even death from heat stroke. Always lock your vehicle whenever you leave it. Outsiders can easily enter through an unlocked door when you slow down or stop your vehicle. Locking your doors can help prevent this from happening.

Programmable Automatic Door Locks If your vehicle has power door locks, it is equipped with a feature that enables you to program the door locks. Your vehicle left the factory programmed to automatically lock all doors when the vehicle is out of PARK (P), and all doors unlock when the vehicle is in PARK (P). You can set the automatic door lock feature to unlock the doors you select once the vehicle is in PARK (P). If your vehicle has a manual transmission it left the factory programmed to lock all doors when the vehicle speed is greater than 8 mph (1 2 km/h) for two seconds, and unlock all doors once the key is removed from the ignition. You can set the automatic door lock feature to unlock the doors you select once the key is removed from the ignition. The following instructions detail how to program your door locks.

Delayed Locking

If your vehicle is a Crew Cab, it may be equipped with this feature. When you lock the doors using the power lock switch or the remote keyless entry transmitter with any door open three chimes will signal that delayed locking is being used. Five seconds after the last door is closed, all the doors will lock. All doors can be re-opened for up to five seconds from the time the last door is closed. You can lock the door immediately using the power door lock switch or the optional remote keyless entry transmitter a second time. This feature will not lock the doors if the key is in the ignition.

Theft-Deterrent Systems 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. Content Theft-Deterrent Your vehicle may be 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), to let you know that you are activating the system.

This message reminds you to activate the theft-deterrent system. Here’s how to do it: 1. Open the door. 2. Lock the door with the power door lock switch or

the remote keyless entry transmitter. The security light should come on and flash. If using the remote keyless entry transmitter, the door does no1 need to be open. If the delayed locking feature is active, the alarm will not be activated until all doors are closed and the security light goes off.

3. Close all doors. The security light will stop flashing

and stay solid. The light should go off after approximately 30 seconds. The alarm is not armed until the security light goes off.

2-1 8

If a door is opened without the key or the remote keyless entry transmitter, the alarm will go off. Your vehicle’s headlamps will flash and the horn will sound for about two minutes, then will turn off to save the battery power. Remember, the theft-deterrent system won’t activate it 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 the system has been armed.

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 or by placing the key in the ignition and turning it to START.

Testing the Alarm The alarm can be tested by following these steps:

1.

2.

3.

4.

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.

If the alarm does not sound when it should but the vehicle’s headlamps flash, check to see if the horn works. The horn fuse may be blown. To replace the fuse, see Fuses and Circuit Breakers on page 5-1 71. If the alarm does not sound or the vehicle’s headlamps do not flash, the vehicle should be serviced by an authorized service center.

Passlock@ Your vehicle is equipped with the Passlock@ theft-deterrent svstern. Passlock@ is a passive theft-deterrent system. Passlock@ enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder is tampered with, fuel is disabled. If the engine stalls and the security light flashes, wait until the light stops flashing before trying to restart the engine. Remember to release the key from START as soon as the engine starts.

If the engine is running 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 Passiock@ at this time. You may also want to check the fuse (see Fuses and Circuit Breakers on page 5- 1 I 1.) See your

Starting and Operating Your Vehicle

New Vehicle Break-In

Nofice: 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 k d h ) or less for the first 500 miles (805 km). Don’t drive at any one speed - fast or 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.

Ignition Positions With the key in the ignition switch, you can turn it to four different positions.

A (LOCK): This position locks your ignition and manual transmission. It’s a theft-deterrent feature. You will only be able to remove your key when the ignition is turned to LOCK.

2-2 1

B (ACCESSORY): This position allows you to use things like the radio, power windows and the windshield wipers when the engine is off.

Key Release Button (Manual Transmission)

The ignition key cannot be removed from the ignition of manual transmission vehicles unless the

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? Turn the key only with your hand. Using a tool to force it could break the key or the ignition switch. If none of these works, then your vehicle needs service.

To remove the key on manual transmission vehicles, turn the key to ACC, then press the button and turn the key to LOCK. Do not hold the button in while turning the key to ACC. Pull the key straight out.

C (RUN): This is the position for driving.

D (START): This position starts your engine.

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. Manual Transmission The gear selector should be in neutral and the parking brake engaged. Hold the clutch pedal to the floor and start the engine. Your vehicle won’t start if the clutch pedal is not all the way down - that’s a safety feature.

Retained Accessory Power (RAP) Your vehicle may be equipped with a Retained Accessory Power (RAP) feature which will allow certain features on your vehicle to continue to work up to 10 minutes after the ignition key is turned to OFF. Your radio, power windows and overhead console will work when the ignition key is in RUN or ACCESSORY. Once the key is turned from RUN to LOCK, these features will continue to work for up to 10 minutes or until a door is opened. Starting Your Engine Automatic Transmission 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. If you have a diesel engine refer to the diesel supplement for starting procedure.

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

stops), it could be flooded with too much gasoline. Try pushing your accelerator pedal all the way to the floor and holding it there as you hold the key in START for about three seconds. When the engine starts, let go of the key and accelerator. If the vehicle starts briefly but then stops again, do the same thing, but this time keep the pedal down for five or six seconds. This clears the extra gasoline from the engine.

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.

Starting Your V8 Engine 1. With your foot off the accelerator pedal, turn the ignition key to START. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm.

Notice: Holding your key in START for longer than 15 seconds at a time will cause your battery to be drained much sooner. And the excessive heat can damage your starter motor. Wait about 15 seconds between each try to help avoid draining your battery or damaging your starter. 2. If it doesn’t start within 10 seconds, push the

accelerator pedal all the way to the floor, while you hold the ignition key in START. When the engine starts, let go of the key and let up on the accelerator pedal. Wait about 15 seconds between each try.

When starting your engine in very cold weather (below 0°F or -18°C)’ do this: 1. With your foot off the accelerator pedal, turn the

ignition key to START and hold it there up to 15 seconds. When the engine starts, let go of the key.

2-24

Engine Coolant Heater

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.

At temperatures above 32°F (OOC), use of the coolant heater is not required. To Use the Engine Coolant Heater 1. 2.

Turn off the engine. Open the hood and unwrap the electrical cord. The cord is located on the driver’s side of the engine compartment, near the power steering fluid reservoir. If you have a diesel engine, refer to diesel supplement for location. Plug it into a normal, grounded 1 IO-volt AC outlet.

3.

cord into an ungrounded

Plugging t could cause an electrical shock. Also, the wrong kind of extension cord could overheat 1 and cause a fire. You could be seriously

injured. Plug the cord into a properly grounded three-prong 11 0-volt AC outlet. If the cord won’t reach, use a heavy-duty three-prong extension cord rated for at least 15 amps.

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.

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.

Automatic Transmission Operation If your vehicle is equipped with an automatic transmission, it features an electronic shift position indicator within the instrument panel cluster. This display must be powered anytime the shift lever is capable of being moved out of PARK (P). See Fuses and Circuit Breakers on page 5- I I 1. There are several different positions for your shift lever. PARK (P): This position locks your rear wheels. It’s the best position to use when you start your engine because your vehicle can’t move easily. If your vehicle is equipped with the Allison@ Transmission, use park for stationary operation of the Power Takeoff (PTO) (if equipped).

REVERSE (R): Use this gear to back up. If your vehicle is equipped with the Allison Transmission, the R may blink on the PRNDL if the shift inhibitor is active. 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 If You Are Stuck: In Sand, Mud, /ce or Snow on page 4-50. 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.

ShiftLJ into a drive gear 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 into a drive gear 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:

Going less than about 35 mph (55 km/h), push your accelerator pedal about halfway down.

0 Going about 35 mph (55 km/h) or more, push the

accelerator all the way down.

You’ll shift down to the next gear and have more power.

2-27

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. Notice: If your vehicle is equipped with the Allision@ Transmission, do not idle in DRIVE (D) for more than five minutes. Extended idling in DRIVE (D) may cause transmission overheating and damage. Always select PARK (P) if idle time is longer than five minutes. If your vehicle is equipped with the Allison@ Transmission, it will initially attain first range when DRIVE (D) is selected. As vehicle speed increases, the transmission will upshift automatically through each available range up to FIFTH (5). As the vehicle slows. the transmission will downshift automatically. 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 won’t turn, 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 (OOC) or colder, your transmission is designed to shift differently until the engine reaches normal operating temperature. This is intended to improve heater performance.

Tow/HauI Mode (Automatic Transmission)

Overdrive Disable (Allison Transmissions)

Your vehicle may be equipped with a tow/haul mode. The selector button is located on the end of the column shift lever. You can use this feature to assist when towing or hauling a heavy load. Turn tow/haul on and off by pressing the button until the tow/haul indicator light illuminates on the instrument panel. See “Tow/Haul Mode” under Towing a Trailer on page 4-66 for more information.

If your vehicle has an Allison Transmission you may have the overdrive disable feature. The overdrive disable feature prevents the transmission from shifting into fifth (5) gear. The selector button is located on the end of the column shift lever. You can turn overdrive disable on and off by pressing and holding the button at the end of the column shift lever until the indicator light, on the instrument panel, illuminates.

2-29

If your vehicle has both tow/haul and overdrive disable tap the button once to enable or disable tow/haul, and press and hold the button to enable or disable overdrive disable. Manual Transmission Operation Five-Speed (VORTEC 6000 V8 Engine)

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.

2-30

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 FIRST (1) until vehicle speed is reduced. 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 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. NEUTRAL: 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 into REVERSE (R) only after your vehicle is stopped. Shifting into REVERSE (R) while your vehicle is moving could damage your transmission. The repairs would not be covered by your warranty. Also, use REVERSE (R), along with the parking brake, when turning off your engine and parking your vehicle.

Five-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 (I), put the shift lever into NEUTRAL 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.

NEUTRAL: 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. Nofice: Shift into REVERSE (R) only after your vehicle is stopped. Shifting into REVERSE (R) while your vehicle is moving could damage your transmission. The repairs would not be covered by your warranty. Also, use REVERSE (R), along with the parking brake, when turning off your engine and parking your vehicle.

2-32

Six-Speed (VORTEC 8100 V8 and DURAMAXTM 6600 V8 Engines)

Here’s how to operate your transmission.

This six-speed pattern is unique to GM manual transmissions. The transmission always repositions the shift lever to NEUTRAL, which is located between FOURTH (4) and FIFTH (5) gear. To prevent unintentional gear selections, additional force is required to move the shift lever into REVERSE (R) or FIRST (1). Use FIRST (1) when trailer towing, driving with payload in the pickup box or launching on a grade. Otherwise, start in SECOND (2) gear. Only shift into FIRST (1) when the vehicle has stopped moving.

THIRD (3): Press the clutch pedal and upshift into THIRD (3). Then, slowly let up on the clutch pedal as you press the accelerator pedal. FOURTH (4), FIFTH (5) and SIXTH (6): Upshift into the higher forward gears the same way as you do THIRD (3). Slowly let up on the clutch pedal as you press the accelerator pedal.

NEUTRAL: Use this position when you start or idle your engine. REVERSE (R): To back up, press the clutch pedal. Wait for the vehicle to stop moving and then, shift to REVERSE (R). Let up on the clutch slowly while pressing the accelerator pedal. Also, use REVERSE (R), along with the parking brake, when turning off your engine and parking your vehicle.

During the first 500 miles (805 km) of vehicle use, start the vehicle moving in FIRST (1) gear. This allows the clutch components to wear-in properly.

FIRST (1): With the vehicle at a stop, release the brake, press the clutch pedai and shift into FIRST (1). Then, slowly let up on the clutch pedal as you press the accelerator pedal. Only downshift into FIRST (1) when the vehicle has come to a complete stop. If the shift lever will not go into FIRST (I), put the lever in NEUTRAL and let up on the clutch pedal to fully engage the clutch. Press the clutch pedal again. Then, shift into FIRST (1). SECOND (2): With the vehicle at a stop, release the brake, press the clutch pedal and shift into SECOND (2). Then, slowly let up on the clutch pedal as you press the accelerator pedal. With the vehicle moving, press the clutch pedal and upshift into SECOND (2) from FIRST (1) while applying light pressure to the right on the shifter. Then, slowly let up on the clutch pedal as you press the accelerator pedal. If you come to a complete stop and the shift lever will not go into SECOND (2), put the lever in NEUTRAL and let up on the clutch pedal to fully engage the clutch. Press the clutch pedal again. Then, shift into SECOND (2).

2-33

Shift Speeds

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.

Do not allow the engine rpm to overspeed and enter the tachometer red lines. Engine overspeed occurs when downshifting, or descending a grade, at too high a vehicle speed. When going down steep grades, always select a gear at least one position lower than you would use on climbing a grade. This will allow the vehicle's engine to provide some braking and help to slow the vehicle as it goes down the grade. Monitor your vehicle speed, acceleration and engine rpm while applying the brakes as you go down the grade to ensure you have complete control over the vehicle.

If your engine speed drops below 600 rpm, or if the engine is not running smoothly, you should downshift to the next lower gear. When operating on slippery surfaces, downshift at lower than normal vehicle speeds to prevent the tires from slipping. In bench seat equipped vehicles, move the tallest beverage containers to the right cupholder to provide additional clearance for the shift lever. For vehicles equipped with a center console, the front cup holder pulls out and turns 180" to provide additional clearance between tall beverage containers and the shift lever. Shift Light

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.

2-34

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.

Four-wheel Drive 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 (4HI) or 4-WHEEL LOW (4LO) 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. Manual Transfer Case

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.

2-35

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

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

An indicator on the bezel near the lever shows you the transfer case settings: 2-Wheel High (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. 4-Wheel High (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 I - use when plowing snow.

Shllklng the transfer case to hcJTRAL 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. 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 RUN in order to shift the lever into NEUTRAL (N). See Recreational Vehicle Towing on page 4-53 or Towing Your Vehicle on page 4-53. 4-Wheel Low (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. You can shift from 2-Wheel High (2HI) to 4-Wheel High (4HI) or from 4-Wheel High (4HI) to 2-Wheel High (2HI) 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 (4HI). To shift into or out of 4-Wheel Low (4LO) 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 (4LO), or your gears could clash. Remember that driving in 4-Wheel High (4HI) or 4-Wheel Low (4LO) 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. Automatic Transfer Case

Shifting the transfer case 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 on page 4-53 or Towing Your Vehicle on page 4-53 for more information. Indicator lights in the switches show which setting your transfer case is 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 the transfer case is being shifted. 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 on page 5-3 for further information. Shifting into 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 into 2HI Press and release the 2Hl switch. This can be done at any speed (except when shifting from 4LO).

Shifting into 4LO To shift to 4L0, 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 4L0 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.

The transfer case will shift to 4HI while waiting to complete the shift. Shifting from 4L0 to 4HI or 2HI To shift from 4LO to 4HI or 2H1, your 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 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 switch. You must wait for the 4HI 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 will not complete the shift unless the vehicle is moving slower than 3 mph (4.8 km/h) and the transmission is in NEUTRAL (N). Shifting into 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 4L0 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). IO. Release the parking brake prior to towing.

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. A chime will activate and the warning light will flash when the parking brake is applied and the vehicle is moving at least 3 mph (5 km/h) for at least three seconds.

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, 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.

Excessively shifting the transfer case into or out of the different modes may cause the transfer case to enter the shift protection mode. This will protect the transfer case from possible damage and will only allow the transfer case to respond to one shift per 10 seconds. The transfer case may stay in this mode for up to three minutes.

2-44

To release the parking brake, hold the regular brake pedal down. Pull the bottom edge of the lever, located above the parking brake pedal, with the parking brake symbol, 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 couid also damage other parts of your vehicle. If you are towing a trailer and are parking on any hill, see Towing a Trailer on page 4-66. Shiftina Ir Park (P)

Leaving Your Vehicle With the Engine Running (Automatic Transmis^:on Only)

It can be dangerous to leave your vehic wi 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, 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. 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 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)”. 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)

Par'-'ng Your Yehi-'e

If 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 Operation on page 2-26. 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 LOCK. 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.

Shifting the transfer case to NEUTRAL can cause your vehicle to roll even if the manual transmission is in gear. Your 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.

Before you get out of your vehicle, move the shift lever into REVERSE (R), and firmly apply the parking brake. Once the shift lever has been placed into REVERSE (R) with the clutch pedal pressed in, you can turn the ignition key to LOCK, remove the key and release the clutch. If you are parking on a hill, or if you are pulling a trailer, see Towing a Trailer on page 4-66.

Parking Over Things That Burn

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

Your exhaust system sounds strange or different. Your vehicle gets rusty underneath. Your vehicle was damaged in a collision. Your vehicle was damaged when driving over high points on the road or over road debris. Repairs weren’t done correctly. Your vehicle or exhaust system had been modified improperly.

If you ever suspect exhaust is coming into your vehicle:

Drive it only with all the windows down to blow out any CO; and Have your vehicle fixed immediately.

2-49

I-

1 ,,,rigs tknmb 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.

Also, idling in a closed-in place can let deadly carbon monoxide (CO) into your vehicle even if the fan 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 “Winter Driving” in the Index.

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

Idling the engine with the climate control system off could allow dangerous exhaust into your vehicle. See the earlier Caution under “Engine Exhaust.”

Four-wheel drive vehicles with the transfer case in NEUTRAL 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. Always set your parking brake.

Follow the proper steps to be sure your vehicle won’t move. See Shifting Into Park (P) on page 2-45. If you’re pulling a trailer, see Towing a Trailer on page 4-66.

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).

Mirrors

Manual Rearview Mirror Pull the tab under the mirror toward you to reduce glare from headlamps behind you after dark. Push the tab away from you for normal daytime operation. Automatic Dimming Rearview Mirror with Onstar@, Compass and Temperature Display Your vehicle may have this feature. When on, an electrochromic mirror automatically dims to the proper level to minimize glare from lights behind you after dark.

2-52

The mirror also includes a duel display in the upper right corner of the mirror face. The compass reading and the outside temperature will both appear in the display at the same time.

(On/Off): This is the on/off button.

Temperature and Compass Display Press the on/off button, located to the far left, briefly to turn the comp/temp display on or off. If the display reads CAL, you will need to calibrate the compass. For more information on calibration, see below. To adjust between Fahrenheit and Celsius do the following:

1.

2.

Press and hold the on/off button for approximately four seconds until either a flashing O F , or "C appears. Press the button again to change the display to the desired unit of measurement. After approximately four seconds of inactivity, the new unit will be locked in and the compass/temperature display will return.

Electrochromic Mirror Operation The electrochromic (self dimming) mirror function is turned on automatically each time the ignition is started. To operate the electrochromic mirror do the following: 1. Make sure the green indicator light, located to

the left of the on/off button, is lit. If it’s not, press and hold the on/off button for approximately six seconds until the green light comes on, indicating that the mirror is in electrochromic (self dimming) mode.

2. Turn off the electrochromic mirror function by

pressing and holding the on/off button for approximately six seconds until the green indicator light turns off.

Compass Variance The mirror is set in zone eight upon leaving the factory. It will be necessary to adjust the compass to compensate for compass variance if you live outside of zone eight. Under certain circumstances, as during a long distance cross-country trip, it will be necessary to adjust for compass variance. Compass variance is the difference between earth’s magnetic north and true geographic north. If not adjusted to account for compass variance, your compass could give false readings.

To adjust for compass variance do the following: 1. Find your current location and variance zone

number on the following zone map.

2. Press and hold the on/off button until a Z and a

zone number appears in the display. The compass is now in zone mode.

2-53

3.

Keep pressing the on/off button until the desired zone number appears in the display. Release the button. After approximately four seconds of inactivity, the new zone number will be locked in and the comp/temp display will return. Calibrate the compass as described below.

4. Compass Calibration The compass may need calibration if one of the following occurs:

After approximately five seconds, the display does not show a compass heading (N for North, for example), there may be a strong magnetic field interfering with the compass. Such interference may be caused by a magnetic antenna mount, magnetic note pad holder or a similar magnetic item. The compass does not display the correct heading and the compass zone variance is set correctly.

In order to calibrate, CAL must be displayed in the mirror compass windows. If CAL is not displayed, push the on/off button for approximately 12 seconds or until CAL is displayed. The compass can be calibrated in one of two ways:

Drive the vehicle in circles at 5 mph (8 km/h) or less until the display reads a direction, or

0 drive the vehicle on your everyday routine and after

several turns the compass will become calibrated and will display a direction.
