INTER-AXLE DIFFERENTIAL LOCK (POWER DIVIDER)

The inter-axle differential, also referred to as the Power Divider, allows
each axle to turn independently, which relieves stress on the rear axles
and reduces tyre wear. A switch on the accessory switch panel locks the
inter-axle differential, which gives you better traction for slippery surfaces.
You will notice the switch has a guard to protect you from activating it
accidentally.

INTER-AXLE DIFFERENTIAL LOCK OPERATION

To LOCK the inter-axle differential:
1. Anticipate when you might need increased traction, slow down
to a steady speed under 40km or stop the vehicle. Do not lock
the differential while going down steep grades or travelling faster
than 40km, or while wheels are spinning or traction is minimal.
Lock the differential before you encounter these conditions.
2. Put the inter-axle differential lock switch in the LOCK position. A
light in the warning cluster will turn on, indicating the differential is
locked (engaged).
3. If you LOCK or UNLOCK the differential while moving, let up
momentarily on the accelerator pedal to relieve torque on the
gearing and allow full engagement of the clutch (mechanism that
locks the wheels).
4. Drive the vehicle through the poor traction area, keeping your
speed under 40km.
