AXLE LOCKER SYSTEM — POWER WAGON
MODELS ONLY (IF EQUIPPED)
This vehicle is equipped with electronically
locking front and rear differentials. These
differentials, when engaged, mechanically lock
together the axle shafts forcing the wheels to
spin at an equal rate. This allows the vehicle to
maintain its momentum and prevents it from
becoming stuck. The locking front and rear
differentials should only be engaged during
low-speed, extreme off-road situations where
one wheel is likely to not be in contact with the
ground. It is not recommended to drive the
vehicle with the differentials locked on
pavement due to the reduced ability to turn and
speed limitations.
Axle Lock Selector
The locking axles are controlled by the axle
locker switch.
The switch has three positions:
AXLE UNLOCK – the front and rear axles are
unlocked
REAR LOCK – the rear axle is locked
FRONT/REAR LOCK – the front and rear axles
are locked
Under normal driving conditions, the switch
should be left in the AXLE UNLOCK position.
NOTE:
Even when the axles are in the AXLE UNLOCK
position, the limited slip differential in the rear
axle still provides torque biasing capability for
moderate low traction environments.
During the command to lock the axle, the
indicator light will flash until the axle is locked.
After the lock command has been successfully
executed, the light will remain on solid.
To lock the rear axle, place the vehicle in 4LO.
Refer to “Four Wheel Drive Operation” in
“Starting And Operating” for further
information. Push the REAR LOCK button while
traveling less than 3 mph (5 km/h). The RR
indicator light will remain on when the rear axle
is locked.
NOTE:
Left to right wheel speed difference may be
necessary to allow the axle to fully lock. If the
indicator light is flashing after placing the switch
in the REAR LOCK or FRONT/REAR LOCK posi
-
tion, drive the vehicle in a turn or on loose gravel
to expedite the locking action.
CAUTION!
Do not lock the front or rear axle on hard
surfaced roads. The ability to steer the
vehicle is reduced and damage to the drive
-
train may occur when the axles are locked
on hard surfaced roads.
Do not try to lock the rear axle if the vehicle
is stuck and the tires are spinning. You can
damage drivetrain components. Lock the
rear axle before attempting situations or
navigating terrain, which could possibly
cause the vehicle to become stuck.
