If your vehicle has this system, you will see the buttons shown below. With this system, engine power is sent to all four wheels when you select the AWD button.

The transfer case buttons are located to the left of the instrument panel cluster. Use these buttons to shift between the various modes of four-wheel drive.

All-wheel drive is like four-wheel drive, but there is no separate lever or switch to engage or disengage the front axle. It is fully automatic, and when combined with StabiliTrak®, the all-wheel drive system adjusts itself as needed for road conditions.

The three modes you can choose between are:

(StabiliTrak®): This button is used to enable or disable the StabiliTrak® and is also used to shift the transfer case into Neutral (N). For more information on using StabiliTrak®, see StabiliTrak® System .

(All-Wheel Drive): This button allows the transfer case to distribute power to all four wheels as needed depending on road and driving conditions.

4 (4LO): This button allows the transfer case to deliver extra torque to the wheels, and provides for precise control of wheel speed by engine braking. You may never need this setting. It sends maximum power to all four wheels. You might choose four-wheel low if you are driving off-road in deep sand, deep mud, deep snow, and while climbing or descending steep hills.

Caution: Shifting the transfer case to N (Neutral) can cause the vehicle to roll even if the transmission is in P (Park). You or someone else could be seriously injured. Be sure to set the parking brake before placing the transfer case in N (Neutral). See Parking Brake .

N (Neutral): Shift the vehicle's transfer case to NEUTRAL only when towing your vehicle. See Recreational Vehicle Towing or Towing Your Vehicle for more information.

Indicator lights in the buttons show which mode you are in. The indicator lights will come on briefly when you turn on the ignition and one will stay on. If the lights do not come on, you should take your vehicle to your dealer for service. An indicator light will flash while the transfer case is shifting . It will remain on 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 message stays on, you should take your vehicle to your dealer for service. See SERVICE 4WD under Driver Information Center (DIC) .

Shifting Into Four Wheel Low

To shift to the Four-Wheel Low position, 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). Press and release the Four-Wheel Low switch. You must wait for the Four-Wheel Low indicator light to stop flashing and remain on before shifting your transmission in 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 the vehicle, always wait for the Four-Wheel Drive Low indicator light to stop flashing before shifting the transmission into gear.

If the Four-Wheel Low button is pressed when your vehicle is in gear and/or moving, the Four-Wheel Low indicator light will flash for 30 seconds and not complete the shift unless your vehicle is moving less than 3 mph (5 km/h) and the transmission is in NEUTRAL (N). After 30 seconds, the transfer case will return to the setting last chosen.

When in Four-Wheel Low, StabiliTrak® is automatically disabled. For more information see StabiliTrak® System .

Shifting Out of Four Wheel-Low

To shift from Four-Wheel Low to All-Wheel Drive, 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. Press and release the all-wheel drive button. You must wait for the All-Wheel Drive indicator light to stop flashing and remain illuminated before shifting your transmission into gear.

If the All-Wheel Drive button is pressed when your vehicle is in gear and/or moving, the All-Wheel Drive indicator light will flash for 30 seconds but will not complete the shift unless your vehicle is moving less than 3 mph (5 km/h) and the transmission is in NEUTRAL (N).

Shifting Into NEUTRAL

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.
3. Start the vehicle or turn the ignition to RUN.
4. Put the transmission in NEUTRAL (N).
5. Shift the transfer case to All-Wheel Drive.
6. Simultaneously press and hold the StabiliTrak® and four-wheel 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, verify that the transmission is in NEUTRAL (N) by shifting the transmission to REVERSE (R) for one second, then shift the transmission to DRIVE (D) for one second.
8. Place the transmission shift lever in PARK (P).
9. Turn the ignition to LOCK.

Shifting Out of NEUTRAL

To shift out of NEUTRAL do the following:

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 (All-Wheel Drive or Four-Wheel Low).
4. After the transfer case has shifted out of NEUTRAL the NEUTRAL light will go out.
