If your vehicle has this feature, the switch is located in the center of the instrument panel.

If you're approaching a slippery surface where it looks like one or even all of the wheels may start to slip, you can press the bottom of this switch. It locks your rear differentials so that power is transmitted equally to both rear axles.

Let up on the accelerator before you turn on your inter-axle differential lock. When you turn on this control, the DIFF LOCK indicator on the center of the instrument panel will light.

Notice: Turning on the inter-axle differential lock while the rear wheels are spinning freely, as they might on snow or ice, can damage the axle(s). Turn on this control only while the wheels are not spinning freely.
