Driving and Operating 9-39 Four-Wheel Drive (Single Speed Automatic Transfer Case) If the vehicle has four-wheel drive, you can send the engine's driving power to all four wheels for extra traction. Read the following before using four-wheel drive. Notice: Driving on clean, dry pavement in Four-Wheel Drive High 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 for extended periods of time. While driving on clean dry pavement and during tight turns, you may experience a vibration in the steering system. 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. The vehicle has Four-Wheel Drive with StabiliTrak®. For information on StabiliTrak, see StabiliTrak® System on page 9‑43. You can choose among three driving settings: Indicator lights in the switch 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 the vehicle to your dealer for service. An indicator light will flash while shifting. 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 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. Automatic Transfer Case The transfer case knob is located to the left of the instrument panel cluster. Use this dial to shift into and out of four-wheel drive.
