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 lock
buttons.
Under normal driving conditions, the vehicle
should be left in the AXLE UNLOCK position.
NOTE:
Even when the axles are in the AXLE UNLOCK
pos
ition, 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 4WD Low,
4WD High or two-wheel drive
Ú page 150. Push
the REAR LOCK button while traveling less than
10
mph (16 km/h). The REAR LOCK indicator light
w
i
ll remain on when the rear axle is locked.
1 FRONT/REAR LOCK the front and rear axles
ar
e locked
2 — REAR LOCK – the rear axle is locked
3 — AXLE UNLOCK – the front and rear axles are
unlocked
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 drivetrain 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 navi
-
gating terrain, which could possibly cause the
vehicle to become stuck.
CAUTION!
