428 STARTING AND OPERATING

AXLE LOCKER SYSTEM (2500 MODELS ONLY) —

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 situa-

tions 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.

• 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 navigating terrain, which

could possibly cause the vehicle to become stuck.

The locking axles are controlled by the axle locker switch.

The switch has three positions, AXLE UNLOCK, REAR

LOCK, and FRONT/REAR LOCK. Under normal driv-

ing conditions, the switch should be left in the AXLE

UNLOCK position. In the AXLE UNLOCK position, the

front and rear axles are unlocked. In the REAR LOCK
