If the vehicle has a controlled traction or locking differential axle, the switch is located in the center of the instrument panel.

This control is on single rear axle vehicles.

If approaching a slippery surface where one or both wheels may start to slip, press the switch to off. The rear differential locks so power is transmitted equally to both rear wheels.

Let up on the accelerator before turning on the rear axle differential lock.

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.

Interaxle Differential Lock

This switch is located on the center instrument panel. This control is on tandem rear axle vehicles.

Press the switch to engage/lock the tandem front axle differential to the rear axle differential. This driver controlled feature improves traction over slippery or uneven surfaces.
