AXLE LOCKER SYSTEM —IF EQUIPPED
This vehicle is equipped with an electronically locking rear
differential. Power Wagon also includes a locking front
differential. 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 differentials, rear or front, 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
one or both of the differentials locked on pavement due to
the reduced ability to turn and speed limitations.
