2007 Chevrolet Silverado Owners Manual

when driving on hilly, winding roads, when towing a trailer, so there is less shifting between gears and when going down a steep hill.

SECOND (2): This position reduces vehicle speed even more than THIRD (3) without using your brakes. 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 an automatic transmission, the transmission will start in second gear. You can 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.

144

For an Allison Transmission®, see Low Traction Mode later in this section. FIRST (1): For an automatic transmission, this position reduces vehicle speed even more than SECOND (2) without using your brakes. You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in FIRST (1) while the vehicle is moving forward, the transmission will not shift into first gear until the vehicle is going slowly enough. For an Allison Transmission®, This position reduces vehicle speed, without using your brakes. You can use it for major/sever downgrades and off-road driving where the vehicle would otherwise accelerate due to steepness of grade. When you shift to FIRST (1) it will provide the lowest gear appropriate to your current road speed and will continue to downshift as the vehicle slows, eventually downshifting to FIRST (1) gear. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. The repair will not be covered by your warranty. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place.

Range Selection Mode (Allison Transmission®)

If your truck has an Allison Transmission® your vehicle has a Range Selection System.

To use this feature, do the following: 1. Move the shift lever to the MANUAL

MODE (M). When in the MANUAL MODE, the transmission’s current gear range will be the highest attainable range with all the lower gears available.

2. Press the plus/minus buttons to select the

desired range of gears for your current driving conditions. The Range Selection Mode allows you to control the engine and vehicle speed while driving down hill by allowing you to select a desired gear.

The DIC shows the six available ranges with the highest attainable range shown in brackets. See Driver Information Center (DIC) on page 263
and DIC Operation and Displays on page 264
for more information. While using the Range Selection mode, cruise control and the Tow/Haul mode can be used. Grade braking is not available while in the Range Selection mode. See Tow/Haul Mode on page 147 for more information.

145

Low Traction Mode (Allison Transmission®) If your vehicle has the DURAMAX® diesel engine and the Allison Transmission®, it has a Low Traction Mode that assists in vehicle acceleration when road conditions are slippery, such as with ice or snow. While at a stop, selecting the second gear range using the Range Selection system, will allow the Allison Transmission® to limit torque to the wheels after it detects wheel slip, preventing the tires from spinning. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. The repair will not be covered by your warranty. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place.

Cold Weather Operation (Allison Transmission®) On cold days, approximately 32°F (0°C) or colder, your automatic transmission is designed to shift differently. The transmission uses a warm-up mode shift schedule until the engine reaches normal operating temperature. While the transmission is in warm-up mode it is normal for transmission upshifts to be delayed or held longer. This feature improves heater performance by giving quicker vehicle warm-ups. When temperatures are below −13°F (−25°C), the transmission will prevent certain operations to protect against damage. When active the DIC will display the message “Trans in Warm-up”. See DIC Warnings and Messages on page 267 for more information.

146

Tow/Haul Mode

The selector button is located on the end of the shift lever. Turn the Tow/Haul on and off by pressing the button. When the Tow/Haul is on, a light on the instrument panel cluster will come on. See Tow/Haul Mode Light on page 262 for more information. If your vehicle has the Performance Package-Enhanced Towing, activating the manual selectable ride will adjust the shock absorber characteristics to enhance the ride and handling of the vehicle for towing or hauling heavy loads. Also see Tow Haul Mode under Towing a Trailer on page 423 for more information.

If your vehicle has an automatic transmission, it may have a Tow/Haul mode. If your vehicle has an Allison Transmission® see “Tow/Haul Mode (Allison Transmission®) following. Tow/Haul mode adjusts the transmission shift pattern to reduce shift cycling, providing increased performance, vehicle control, and transmission cooling when towing or hauling heavy loads.

147

Tow/Haul Mode (Allison Transmission®)

If your vehicle has an Allison Transmission®, it may have a Tow/Haul mode. Tow/Haul mode adjusts the transmission shift pattern to reduce shift cycling, providing increased performance, vehicle control, and transmission cooling when towing or hauling heavy loads.

148

The selector button is located on the end of the shift lever. Turn the Tow/Haul on and off by pressing the button. When the Tow/Haul is on, a light on the instrument panel cluster will come on. See Tow/Haul Mode Light on page 262 for more information. Also see “Tow Haul Mode” under Towing a Trailer on page 423 for more information. Grade Braking and Cruise Grade Braking (Allison Transmission®) Grade Braking and Cruise Grade Braking assists when driving on a downhill grade. It maintains the vehicle’s speed by automatically using a shift schedule that uses the engine and the transmission to slow the vehicle. This reduces wear on the brakes system and increases control of the vehicle. The system constantly monitors the vehicle’s speed, acceleration, engine torque, and brake pedal usage. It detects when the truck is on a downhill grade and the driver’s desire to slow down by pressing the brake.

Cruise Grade Braking is available on the 6.6L DURAMAX® diesel engine. Cruise Grade Braking monitors a vehicle’s cruise state, engine torque, acceleration, vehicle speed, and the cruise set speed. Using this information, it detects when the truck is accelerating on a downhill grade and will automatically downshift to slow the vehicle if it exceeds the cruise set speed by a certain amount. See Cruise Control on page 217 for more information. The Tow/Haul mode and Grade Braking shift modes can be activated by pressing the button on the end of the shift control stalk. If your vehicle has the DURAMAX® diesel Engine or the 8.1L VORTEC™ gasoline engine, Grade Braking is only available while the Tow/Haul Mode is selected. While in the Range Selection Mode, Grade Braking is deactivated allowing the driver to select a desired range of gears. See Automatic Transmission Operation on page 140 for more information. Also see Towing a Trailer on page 423 for more information.

Manual Transmission Operation Five-Speed (VORTEC™ 6.0L V8 Engine)

Here is how to operate your transmission.

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.

149

If you try to shift down into FIRST (1) at

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). Notice: excessive vehicle speeds, clutch or engine damage could occur. Do not shift into FIRST (1) unless you are going less than 5 mph (8km/h). 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 are going less than 20 mph (32 km/h). If you have come to a complete stop and it is 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). Notice: SECOND (2) at excessive vehicle speeds, clutch or engine damage could occur. Do not shift into SECOND (2) unless you are going less than 20
mph (32km/h). 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.

If you try to shift down into

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

Five-Speed (VORTEC™ 4.3L V6 and 4.8L V8 Engines) Here is 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 are going less than 20 mph (32 km/h). If you have come to a complete stop and it is hard to shift into FIRST (1), put the shift lever into NEUTRAL and let up on the clutch. Press the clutch pedal back down. Then shift into FIRST (1). Notice: at excessive vehicle speeds, clutch or engine damage could occur. Do not shift into FIRST (1) unless you are going less than 20 mph (32km/h).

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

151

Shift Speeds

{CAUTION:

If you skip a gear when you downshift, you could lose control of your vehicle. You could injure yourself or others. Do not shift down more than one gear at a time when you downshift.

Do not allow the engine Revolutions Per Minute (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 vehicles that have a bench seat, move the tallest beverage containers to the right cupholder to provide additional clearance for the shift lever. For vehicles that have a center console, the front cup holder pulls out and turns 180° to provide additional clearance between tall beverage containers and the shift lever.

152

Up-Shift Light

If your vehicle has 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 has a manual transmission, disregard the shift light when the transfer case is in Four-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. While driving on clean dry pavement and during tight turns, you may experience a vibration in the steering system. 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.

153

Manual Transfer Case

A 4WD indicator light comes on when you shift into four-wheel drive and the front axle engages. See Four-Wheel-Drive Light on page 261.

Some delay between shifting and when the indicator light comes on is normal.

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

154

An indicator light near the lever shows you the transfer case settings: Notice: Driving on clean, dry pavement in four-wheel drive for an extended period of time may cause premature wear on your vehicle’s powertrain. Do not drive on clean, dry pavement in four-wheel drive for extended periods of time.

4L (Four-Wheel Low): This setting also engages the front axle and delivers extra torque. You may never need 4L. It sends maximum power to all four wheels. You might choose 4L if you are driving off-road in deep sand, deep mud, deep snow, and while climbing or descending steep hills. When operating in 4L, the gear ratio provides additional torque when compared to 4H. The transmission gear shift feel will be exaggerated.

{CAUTION:

Shifting the transfer case to NEUTRAL 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 on page 170.

N (Neutral): Shift to this setting only when your vehicle needs to be towed. See Recreational Vehicle Towing on page 418 or Towing Your Vehicle on page 417.

155

2H (Two-Wheel Drive High): This setting is used for driving in most street and highway situations. The front axle is not engaged in two-wheel drive. This setting also provides the best fuel economy.

4H (Four-Wheel Drive High): Use this setting when you need extra traction, such as on snowy or icy roads or in most off-road situations. This setting also engages the front axle to help drive your vehicle. This is the best setting to use when plowing snow. You can shift from 2H to 4H or 4H to 2H while the vehicle is moving. The 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 4H.

(cid:127)

156

When Using the Manual Transfer Case (cid:127) Shifting should be made using quick motions.

Shifting slowly may make it more difficult to shift.

(cid:127) You may notice that it is harder to shift when

the vehicle is cold. After the vehicle warms up the shifting will return to normal.

(cid:127) While in 4H or 4L you may experience

reduced fuel economy.

(cid:127) Avoid driving in four-wheel drive on clean, dry

pavement. Doing this may cause the tires to wear faster, and make your transfer case harder to shift, and run noisier.

Shifting from 2H (Two-Wheel Drive High) to 4H (Four-Wheel Drive High) (cid:127) Shifts between 2H and 4H can be made at

any vehicle speed. It is easiest to shift the transfer case when maintaining a constant speed or during a slight acceleration. If possible, avoid shifting while slowing down, as it will make it harder to shift.

(cid:127) Shift the transfer case lever in one continuous

(cid:127)

motion into either the 4H or 2H position. In extremely cold weather, it may be necessary to slow or stop the vehicle to shift into 4H until your vehicle has warmed up.

(cid:127) While in 4H, your vehicle can be driven at any

posted legal speed limit.

Shifting In or Out of 4L (Four-Wheel Drive Low) Notice: Shifting the transfer case into 4L while moving at speeds faster than 3 mph (5 km/h) may cause premature wear to the transfer case, and may cause the gears to grind. To avoid causing premature wear, and grinding the gears, do not shift the transfer case into 4L while the vehicle is moving faster than 3 mph (5 km/h).

Shifts into 4L can be made with the vehicle at a stop, or while slowly rolling about 1 to 3 mph (2 to 5 km/h). (cid:127) Shift the automatic transmission into

NEUTRAL (N), or with a manual transmission, press the clutch pedal, or shift into NEUTRAL.

(cid:127) Shift the transfer case shift lever in one continuous motion into the 4L position.

(cid:127) When in 4L do not drive faster than 45 mph. This will reduce wear and extend the life of the transfer case.

Shifting In or Out of NEUTRAL 1. With the vehicle running and the engine at an

idle set the parking brake and apply the regular brake.

2. Place the transmission into NEUTRAL (N). Shift the transfer case in one continuous motion into or out of the NEUTRAL position.

You can choose among five driving settings: Notice: Driving on clean, dry pavement in Four-Wheel-Drive High or Four-Wheel-Drive Low for an extended period of time may cause premature wear on your vehicle’s powertrain. Do not drive on clean, dry pavement in Four-Wheel-Drive High or Four-Wheel-Drive Low for extended periods of time.

Indicator lights in the switches show the current setting. The indicator lights will come on briefly when you turn on the ignition and the last chosen setting 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. Fast flashing means the conditions are not being met to make the desired shift, typically the vehicle is going too fast, the automatic transmission is not in NEUTRAL, or the clutch pedal is not fully pressed. Slow flashing means the shift is in progress. It will stay on when the shift is completed. If for some reason the transfer case cannot make a requested shift, it will return to the last chosen setting.

AUTO 4WD (Automatic Four-Wheel Drive): This setting is ideal for use when road surface traction conditions are variable. When driving your vehicle in AUTO 4WD, the front axle is engaged, but the vehicle’s power is primarily sent to the rear wheels. When the vehicle’s software determines a need for more traction, the system will transfer more power to the front wheels. Driving in this mode results in slightly lower fuel economy than Two-Wheel Drive High.

2 m (Two-Wheel Drive High): 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.

{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 on page 170.

N (NEUTRAL): Shift the vehicle’s transfer case to N (NEUTRAL) only when towing your vehicle. See Recreational Vehicle Towing on page 418 or Towing Your Vehicle on page 417 for more information.

159

Shifting into Four-Wheel Drive High or AUTO 4WD (Automatic Four-Wheel Drive) Press and release the Four-Wheel Drive High or AUTO 4WD switch. This can be done at any speed, except when shifting from Four-Wheel Drive Low. The indicator light will flash while shifting. It will remain on when the shift is completed. Shifting into Two-Wheel Drive High Press and release the Two-Wheel Drive High switch. This can be done at any speed, except when shifting from Four-Wheel Drive Low. See shifting out of Four-Wheel Drive Low later in this section for more information.

4 m (Four-Wheel Drive High): Use this setting when you need extra traction, such a on snowy or icy roads or in most off-road situations. This setting also engages your front axle to help drive the vehicle. This is the best setting to use when plowing snow. 4 n (Four-Wheel Drive Low): This setting also engages the front axle and delivers extra torque. You may never need Four-Wheel Drive Low. It sends maximum power to all four wheels. You might choose Four-Wheel Drive Low if you are driving off-road in deep sand, deep mud, deep snow, and while climbing or descending steep hills. When operating in Four-Wheel Drive Low, the gear ratio provides additional torque when compared to Four-Wheel Drive High. The transmission gear shift feel will be exaggerated. If the SERVICE 4WD message stays on the Driver Information Center (DIC), you should take your vehicle to your dealer for service. See DIC Warnings and Messages on page 267 for further information.

Shifting into Four-Wheel Drive Low Notice: Shifting the transfer case into Four-Wheel Drive Low while moving at speeds faster than 3 mph (5 km/h) may cause premature wear to the transfer case, and may cause the gears to grind. To avoid causing premature wear, and grinding the gears, do not shift the transfer case into Four-Wheel Drive Low while the vehicle is moving faster than 3 mph (5 km/h). To shift to Four-Wheel Drive Low, the ignition must be in RUN and the vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in NEUTRAL (N). The preferred method for shifting into Four-Wheel Drive Low is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Press and release the Four-Wheel Drive Low switch. You must wait for the Four-Wheel Drive Low indicator light to stop flashing and remain on before shifting the transmission into gear.

Notice: Shifting the transmission into gear before the Four-Wheel Drive Low indicator light has stopped flashing could damage the transfer case. To help avoid damaging your vehicle, always wait for the Four-Wheel Drive Low indicator light to stop flashing before shifting the transmission into gear. It is typical for your vehicle to exhibit significant engagement noise and bump when shifting between Four-Wheel Drive Low and Four-Wheel Drive High ranges or from NEUTRAL (N) with the engine running. If the Four-Wheel Drive Low switch is pressed when your vehicle is in gear and/or moving, the Four-Wheel Drive Low indicator light will flash for 30 seconds and the vehicle will not complete the shift unless it is moving less than 3 mph (5 km/h) and the transmission is in NEUTRAL (N). After 30 seconds the transfer case will shift to Four-Wheel Drive High mode.

161

Shifting Out of Four-Wheel Drive Low To shift from Four-Wheel Drive Low to Four-Wheel Drive High, AUTO 4WD, or Two-Wheel Drive High, your vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in NEUTRAL (N) and the ignition in RUN. The preferred method for shifting out of Four-Wheel Drive Low is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Press and release the Four-Wheel Drive High, AUTO 4WD, or Two-Wheel Drive High switch. You must wait for the Four-Wheel Drive High, AUTO 4WD, or Two-Wheel Drive High indicator light to stop flashing and stay on before shifting the transmission into gear.

Notice: Shifting the transmission into gear before the Four-Wheel Drive Low indicator light has stopped flashing could damage the transfer case. To help avoid damaging your vehicle, always wait for the Four-Wheel Drive Low indicator light to stop flashing before shifting the transmission into gear. The transfer case may make noise and the vehicle may jerk when the transfer case is shifted between Four-Wheel Drive Low and Four-Wheel Drive High ranges or from NEUTRAL with the engine running. If the Four-Wheel Drive high, AUTO 4WD, or Two-Wheel Drive High switch is pressed when your vehicle is in gear and/or moving, the Four-Wheel Drive High, AUTO 4WD, or Two-Wheel Drive High indicator light will flash for 30 seconds but the vehicle will not complete the shift unless it is moving less than 3 mph (5 km/h) and the transmission is in NEUTRAL (N).

162

Shifting Into NEUTRAL

{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 on page 170.

To shift the transfer case to NEUTRAL do the following:

1. Make sure the vehicle is parked so that it will

not roll.

2. Set the parking brake and apply the regular

brake pedal.

3. Start the vehicle or turn the ignition to RUN.

4. Put the transmission in NEUTRAL (N). 5. Shift the transfer case to Two-Wheel

Drive High.

6. Simultaneously press and hold the Two-Wheel Drive High and Four-Wheel Drive Low buttons for 10 seconds. The red NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete.

7. If the engine is running, shift the transmission

to REVERSE (R) for one second, then shift the transmission to DRIVE (D) for one second, or FIRST (1) for vehicles that have a manual transmission.

8. Turn the engine off, by turning the key to

ACCESSORY.

9. Place the transmission shift lever in PARK (P). 10. Release the parking brake prior to moving

the vehicle.

11. Turn the ignition to LOCK.

163

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

brake pedal.

2. Turn the ignition to RUN with the engine off. 3. Shift the transmission to NEUTRAL (N). 4. Press the button for the desired transfer case

shift position (Two-Wheel Drive High, Four-Wheel Drive High, AUTO 4WD, or Four-Wheel Drive Low).

5. After the transfer case has shifted out of

NEUTRAL the red light will go out.

6. Release the parking brake prior to moving the

vehicle.

7. 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 mode protects the transfer case from possible damage and only allows the transfer case to respond to one shift per 10 seconds. The transfer case may stay in this mode for up to three minutes.

Use these switches to shift into and out of four-wheel drive. You can choose among three driving settings: Indicator lights in the switches show you which setting you are in. The indicator lights will come on briefly when you turn on the ignition and the last chosen setting will stay on. If the lights do not come on, you should take your vehicle in to your dealer for service. An indicator light will flash while shifting. Fast flashing means the conditions are not being met to make the desired shift, typically the vehicle is going too fast, the automatic transmission is not in neutral, or the clutch pedal is not fully pressed. Slow flashing means the shift is in progress. It will stay on when the shift is completed. If for some reason the transfer case cannot make a requested shift, it will return to the last chosen setting. 2 m (Two-Wheel Drive High): This setting is for driving in most street and highway situations. The front axle is not engaged in two-wheel drive.

{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 on page 170.

(N) NEUTRAL: Shift the vehicle’s transfer case to NEUTRAL only when towing your vehicle. See Recreational Vehicle Towing on page 418 or Towing Your Vehicle on page 417 for more information. 4 m (Four-Wheel Drive High): This setting engages the front axle to help drive your vehicle. Use Four-Wheel Drive High when you need extra traction, such as on snowy or icy roads, or in most off-road situations.

165

4 n (Four-Wheel Drive Low): This setting also engages your front axle to give you extra traction. You may never need Four-Wheel Drive Low. It sends the maximum power to all four wheels. You might choose Four-Wheel Drive Low if you were driving off-road in sand, mud or deep snow and while climbing or descending steep hills. When operating in Four-Wheel Drive Low, the gear ratio provides additional torque when compared to Four-Wheel Drive High. The transmission gear shift feel will be exaggerated. Shifting from Two-Wheel Drive High to Four-Wheel Drive High Press and release the Four-Wheel Drive High switch. This can be done at any speed. The front axle will lock automatically with some delay. Shifting from Four-Wheel Drive High to Two-Wheel Drive High Press and release the Two-Wheel Drive High switch. This can be done at any speed. The front axle will unlock automatically with some delay.

Shifting from Two-Wheel Drive High or Four-Wheel Drive High to Four-Wheel Drive Low To shift from Two-Wheel Drive High or Four-Wheel Drive High to Four-Wheel Drive Low, the vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in NEUTRAL (N) for an automatic transmission, or the clutch pedal pressed for a manual transmission. The preferred method for shifting into Four-Wheel Drive Low is to have your vehicle moving 3 mph (5 km/h). Press and release the Four-Wheel Drive Low switch. You must wait for the Four-Wheel Drive Low indicator light to stop flashing and stay on before shifting the transmission into gear or releasing the clutch pedal. Notice: Shifting the transmission into gear before the Four-Wheel Drive Low indicator light has stopped flashing could damage the transfer case. To help avoid damaging your vehicle, always wait for the Four-Wheel Drive Low indicator light to stop flashing before shifting the transmission into gear.

166

If the Four-Wheel Drive Low switch is pressed when your vehicle is in gear and/or moving, the Four-Wheel Drive Low indicator light will flash for 30 seconds and not complete the shift unless your vehicle is moving slower than 3 mph (5 km/h) and the transmission is in NEUTRAL (N). The transfer case will shift to Four-Wheel Drive High while waiting to complete the shift. It is normal to hear and feel your vehicle’s transfer case shift into Four-Wheel Drive Low. If you shift with the vehicle stopped, the indicator light may continue to flash slowly. It may be necessary to shift the transmission momentarily into REVERSE (R) and DRIVE (D), for an automatic transmission, or REVERSE (R) and FIRST (1) for a manual transmission to make the light stop flashing.

Shifting from Four-Wheel Drive Low to Four-Wheel Drive High or Two-Wheel Drive High To shift from Four-Wheel Drive Low to Four-Wheel Drive High or Two-Wheel Drive High, your vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in NEUTRAL (N) for an automatic transmission or the clutch pedal pressed for a manual transmission. The preferred method for shifting out of Four-Wheel Drive Low is to have your vehicle moving 3 mph (5 km/h). Press and release the Two-Wheel Drive High or Four-Wheel Drive High switch. You must wait for the Two-Wheel Drive High or Four-Wheel Drive High indicator light to stop flashing and stay on before shifting the transmission into gear or releasing the clutch pedal. If the Four-Wheel Drive High switch is pressed when your vehicle is in gear, the Four-Wheel Drive High indicator light will flash for 30 seconds but the vehicle will not complete the shift unless it is moving slower than 3 mph (5 km/h) and the transmission is in NEUTRAL (N).

Shifting into NEUTRAL

{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 on page 170.

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 and apply the regular

brake pedal.

2. Start the vehicle or turn the ignition to RUN. 3. Press the foot brake pedal and put the

transmission in NEUTRAL (N).

4. Shift the transfer case to Two-Wheel

Drive High.

168

5. Simultaneously press and hold the Two-Wheel Drive High and Four-Wheel Drive Low buttons for 10 seconds. The red NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete.

6. Start the engine if it is not already running. 7. Press and hold the foot brake pedal and Shift

the transmission to REVERSE (R) for one second, then shift the transmission for one second to DRIVE (D) for an automatic transmission, or FIRST (1) for vehicles that have a manual transmission. Then let out the clutch. This is to ensure the transfer case is in NEUTRAL. If not, repeat this procedure starting at Step 3.

8. Turn the engine off, by turning the key to

ACCESSORY.

9. Place the transmission shift lever in PARK (P)

for an automatic transmission, or FIRST (1) for vehicles that have a manual transmission. 10. Release the parking brake prior to moving the

vehicle.

11. Turn the ignition to LOCK.

Shifting Out of NEUTRAL To shift out of NEUTRAL: 1. Set the parking brake and press and hold the

regular brake pedal.

2. Shift the transmission to NEUTRAL (N) for an

automatic transmission, or press the clutch pedal for vehicles that have a manual transmission. Then turn the ignition to RUN with the engine off.

3. Press the button for the desired transfer case

shift position (Two-Wheel Drive High, Four-Wheel Drive High, or Four-Wheel Drive Low).

4. After the transfer case has shifted out of

NEUTRAL the red light will go out.

5. Release the parking brake prior to moving

the vehicle.

6. 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 mode protects the transfer case from possible damage and only allows the transfer case to respond to one shift per 10 seconds. The transfer case may stay in this mode for up to three minutes.

7. After the transfer case has shifted out of

NEUTRAL the red light will go out.

169

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.

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 overheat the brake system and cause premature wear or damage to brake system parts. Verify that the parking brake is fully released and the brake warning light is off before driving. If you are towing a trailer and are parking on any hill, see Towing a Trailer on page 423.

170

1. Hold the brake pedal down with your right foot

and set the parking brake.

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

position by pulling the shift lever toward you and moving it up as far as it will go.

3. If your vehicle has four-wheel drive, be sure the transfer case is in a drive gear – not in NEUTRAL.

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).

Shifting Into Park (P) (Automatic Transmission)

{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 will not move, even when you are on fairly level ground, use the steps that follow. With four-wheel drive, if 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. If you are pulling a trailer, see Towing a Trailer on page 423.

171

Leaving Your Vehicle With the Engine Running (Automatic Transmission)

CAUTION:

(Continued)

{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 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. (Continued)

CAUTION:

And, if you leave the vehicle with the engine running, it could overheat and even catch fire. You or others could be injured. Do not 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 was not fully locked into PARK (P).

172

Torque Lock (Automatic Transmission) If you are parking on a hill and you do not 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)” listed earlier in this section. 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) Your vehicle has an automatic transmission shift lock control system which locks the shift lever in PARK (P) when the ignition is in the LOCK position. 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 140 and “Torque Lock” under Shifting Out of Park (P) (Automatic Transmission) on page 173. If your vehicle has an Allison Transmission®, the transmission has a park pawl designed to hold the higher weight of commercial medium duty trucks. Therefore, the Allison Transmission® uses larger parts than other automatic transmissions.

173

These larger parts may sometimes make a clunking noise when the selector lever is moved from DRIVE (D) or REVERSE (R) to PARK (P). This is normal and there is no damage occurring during these shifts. 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 not shift out of PARK (P), try this: 1. Turn the key to ACCESSORY. There is no

shift interlock in this key position.

2. Apply and hold the brake until the end of

Step 4.

3. Shift the transmission to NEUTRAL (N). 4. Start the vehicle and then shift to the gear

you want.

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

174

Parking Over Things That Burn

{CAUTION:

Things that can burn could touch hot exhaust parts under your vehicle and ignite. Do not 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 cannot see or smell. It can cause unconsciousness and death. You might have exhaust coming in if:

(cid:127) Your exhaust system sounds strange

or different.

(cid:127) Your vehicle gets rusty underneath. (cid:127) Your vehicle was damaged in a

collision.

CAUTION:

(Continued)

(cid:127) Your vehicle was damaged when

driving over high points on the road or over road debris.

(cid:127) Repairs were not done correctly. (cid:127) Your vehicle or exhaust system has

been modified improperly.

If you ever suspect exhaust is coming into your vehicle:

(cid:127) Drive it only with all the windows

down to blow out any CO; and

(cid:127) Have your vehicle fixed immediately.

CAUTION:

(Continued)

175

{CAUTION:

It can be dangerous to get out of your vehicle if the automatic transmission shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll. Do not 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 will not move, even when it is on fairly level ground, always set the parking brake and move the automatic transmission shift lever to PARK (P), or the manual transmission shift lever to NEUTRAL.

Running the Engine While Parked It is better not to park with the engine running. But if you ever 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 on page 175. Also, idling in a closed-in place can let deadly carbon monoxide (CO) into your vehicle even if the climate control 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 on page 396.

176

{CAUTION:

Four-wheel drive vehicles with the transfer case in NEUTRAL will allow the vehicle to roll, even if your automatic transmission 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 will not move. See Shifting Into Park (P) (Automatic Transmission) on page 171. If you are pulling a trailer, see Towing a Trailer on page 423.

8. Press and release the button again. The garage door should move, confirming that programming is successful and complete.

To program another device such as an additional garage door opener, a security device, or home lighting, repeat Steps 1 through 8, choosing a different function button in Step 7 than what you used for the garage door opener.

Programming Universal Home Remote — Rolling Code Rolling code garage door openers are used for garage doors produced after 1996 and are code protected. Rolling code means the coded signal is changed every time your remote control garage door opener is used. Programming a rolling code garage door opener involves time-sensitive actions, so read the entire procedure before you begin. If you do not follow these actions, the device will time out and you will have to repeat the procedure. Follow these steps to program up to three channels: 1. Press the two outside buttons at the same

time for one to two seconds, and immediately release them.

2. Go to the garage. Locate the garage door

motor head and press and release the “learn” button. After pressing the “learn” button, you have 10 to 30 seconds to complete Step 4
depending on your garage control unit. If you cannot locate the “learn” button, refer to the owners guide for your garage door opener.

3. Press and hold the button you would like to

use to control the garage door until the garage door moves. The indicator light, above the selected button, should slowly blink. You may need to hold the button from five to 20 seconds.

4. Immediately release the button when the

garage door moves. The indicator light will blink rapidly until programming is complete.

5. Press and release the button again. The garage door should move, confirming that programming is successful and complete.

To program another device such as an additional garage door opener, a security device, or home lighting, repeat Steps 1 through 6, choosing a different function button in Step 4 than what you used for the garage door opener. Using Universal Home Remote Press and hold the appropriate button for at least half of a second. The indicator light will come on while the signal is being transmitted.

Reprogramming Universal Home Remote Buttons You can reprogram any of the three buttons by repeating the instructions. Erasing Universal Home Remote Buttons You should erase the programmed buttons when you sell the vehicle or terminate your lease. To erase either rolling code or fixed code on the Universal Home Remote device, do the following: 1. Press and hold the two outside buttons at

the same time for approximately 20 seconds, until the indicator lights, located directly above the buttons, begin to blink rapidly.

2. Once the indicator lights begin to blink,

release both buttons. The codes from all button will be erased.

Universal Home Remote System Operation (With One Triangular LED)

Your vehicle may have the Universal Home Remote System. If there is one triangular Light Emitting Diode (LED) above the Universal Home Remote buttons, follow the instructions below. If your vehicle has three round LED above the Universal Home Remote buttons, follow the instructions under Universal Home Remote System Operation (with three round LED). Do not use the Universal Home Remote with any garage door opener that does not have the stop and reverse feature. This includes any garage door opener model manufactured before April 1, 1982. If you have a newer garage door opener with rolling codes, please be sure to follow Steps 6 through 8 to complete the programming of your Universal Home Remote Transmitter.

Read the instructions completely before attempting to program the Universal Home Remote. Because of the steps involved, it may be helpful to have another person available to assist you in the programming steps. Keep the original hand-held transmitter for use in other vehicles as well as for future Universal Home Remote programming. It is also recommended that upon the sale of the vehicle, the programmed Universal Home Remote buttons should be erased for security purposes. See “Erasing Universal Home Remote Buttons” later in this section or, for assistance, see Customer Assistance Offices on page 638. Be sure that people and objects are clear of the garage door or gate operator you are programming. When programming a garage door, it is advised to park outside of the garage. It is recommended that a new battery be installed in your hand-held transmitter for quicker and more accurate transmission of the radio-frequency signal.

Programming Universal Home Remote Follow these steps to program up to three channels: 1. Press and hold down the two outside

Universal Home Remote buttons, releasing only when the Universal Home Remote indicator light begins to flash, after 20 seconds. Do not hold down the buttons for longer than 30 seconds and do not repeat this step to program a second and/or third hand-held transmitter to the remaining two Universal Home Remote buttons.

2. Position the end of your hand-held transmitter about 1 to 3 inches (3 to 8 cm) away from the Universal Home Remote buttons while keeping the indicator light in view.

3. Simultaneously press and hold both the desired Universal Home Remote button and the hand-held transmitter button. Do not release the buttons until Step 4 has been completed. Some entry gates and garage door openers may require you to substitute Step 3 with the procedure noted in “Gate Operator and Canadian Programming” later in this section.

4. The indicator light will flash slowly at first and

then rapidly after Universal Home Remote successfully receives the frequency signal from the hand-held transmitter. Release both buttons.

6. Locate in the garage, the garage door opener receiver (motor-head unit). Locate the “Learn” or “Smart” button. This can usually be found where the hanging antenna wire is attached to the motor-head unit.

5. Press and hold the newly-trained Universal

Home Remote button and observe the indicator light. If the indicator light stays on continuously, programming is complete and your device should activate when the Universal Home Remote button is pressed and released. To program the remaining two Universal Home Remote buttons, begin with Step 2 under “Programming Universal Home Remote.” Do not repeat Step 1 as this will erase all of the programmed channels. If the indicator light blinks rapidly for two seconds and then turns to a constant light, continue with Steps 6 through 8 following to complete the programming of a rolling-code device, most commonly, a garage door opener.

7. Firmly press and release the “Learn” or “Smart” button. The name and color of the button may vary by manufacturer. You will have 30 seconds to start Step 8.

8. Return to the vehicle. Firmly press and hold

the programmed Universal Home Remote button for two seconds, then release. Repeat the press/hold/release sequence a second time, and depending on the brand of the garage door opener or other rolling code device, repeat this sequence a third time to complete the programming. The Universal Home Remote should now activate the rolling-code device.

To program the remaining two Universal Home Remote buttons, begin with Step 2 of “Programming Universal Home Remote.” Do not repeat Step 1, as this will erase all previous programming from the Universal Home Remote buttons.

Gate Operator and Canadian Programming Canadian radio-frequency laws require transmitter signals to time out or quit after several seconds of transmission. This may not be long enough for Universal Home Remote to pick up the signal during programming. Similarly, some U.S. gate operators are manufactured to time out in the same manner. If you live in Canada, or you are having difficulty programming a gate operator or garage door opener by using the “Programming Universal Home Remote” procedures, regardless of where you live, replace Step 3 under “Programming Universal Home Remote” with the following: Continue to press and hold the Universal Home Remote button while you press and release every two seconds (cycle) the hand-held transmitter button until the frequency signal has been successfully accepted by the Universal Home Remote. The Universal Home Remote indicator light will flash slowly at first and then rapidly. Proceed with Step 4 under “Programming Universal Home Remote” to complete.

Using Universal Home Remote Press and hold the appropriate Universal Home Remote button for at least half of a second. The indicator light will come on while the signal is
