an extended period of time may cause premature
wear on your vehicle's powertrain. Do not drive on

Four-Wheel Drive Low for extended periods of time.
While driving on clean dry pavement and during tight

Automatic Transfer Case
Use this dial to shift into and out of four-wheel drive.
You can choose among five 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
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.
The transfer case knob is
located to the left of the
instrument panel cluster.
