If your vehicle has this feature, you will find a label on the headliner above the windshield or in another place near the driver that shows how to use it.

The switch is located on the instrument panel to the right of the climate controls. See Instrument Panel Overview for more information.

When the switch is up, the rear axle is in the high range. Push it down to get the low range.

To operate off-road or under a heavy load, shift into low range when the vehicle is standing still and then operate the transmission normally.

On the highway, with the rear axle in low range and the transmission in top gear, you may shift the rear axle to high range by raising the switch and releasing the accelerator momentarily. Reapply the accelerator after you shift.

Under light load conditions, first shift the rear axle into the high range with the vehicle at a standstill and then operate the transmission normally.
