Driving and Operating 9-41 Drive Systems Four-Wheel Drive If the vehicle has Four-Wheel Drive, you can send the 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 following before using Four-Wheel Drive. See the appropriate text for the transfer case in the vehicle. 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 the 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. While driving on clean dry pavement and during tight turns, you may experience vibration in the steering system. If the vehicle has StabiliTrak®, shifting into Four-Wheel Drive Low will turn Traction Control and StabiliTrak off. See StabiliTrak® System on page 9‑56. 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. Front Axle The front axle engages and disengages automatically when you shift the transfer case. Some delay for the axle to engage or disengage is normal. Manual Transfer Case A Four-Wheel Drive indicator light comes on when you shift into four-wheel drive and the front axle engages. See Four-Wheel-Drive Light on page 5‑25. Some delay between shifting and when the indicator light comes on is normal.
