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

above 20 mph (32 km/h), the set speed shall be the current
speed of the vehicle.
NOTE:
ACC cannot be set if there is a stationary vehicle in front of
your vehicle in close proximity.
Remove your foot from the accelerator pedal, after the ACC
has been set. If you do not, the vehicle may continue to accel-
erate beyond the set speed. If this occurs:
• The message “ACC DRIVER OVERRIDE” will display in the instrument cluster display.
• The system will not be controlling the distance between your vehicle and the vehicle ahead. The vehicle speed will
only be determined by the position of the accelerator
pedal.

364 STARTING AND OPERATING
NOTE:
• When you override and push the RES (+) button or SET (-)buttons, the new set speed will be the current speed of the
vehicle.
• When you use the SET (-) button to decelerate, if the engine’s braking power does not slow the vehicle suffi -
ciently to reach the set speed, the brake system will auto -
matically slow the vehicle.
• The ACC system decelerates the vehicle to a full stop when following a target vehicle. If an ACC host vehicle follows a
target vehicle to a standstill, after two seconds the driver
will either have to push the RES (+) button, or apply the
accelerator pedal to reengage the ACC to the existing set
speed.
• The ACC system maintains set speed when driving up hill and down hill. However, a slight speed change on
moderate hills is normal. In addition, downshifting may
occur while climbing uphill or descending downhill. This
is normal operation and necessary to maintain set speed.
When driving up hill and down hill, the ACC system will
cancel if the braking temperature exceeds normal range
(overheated).Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between four bars (longest),
three bars (long), two bars (medium) and one bar (short).
Using this distance setting and the vehicle speed, ACC calcu-
lates and sets the distance to the vehicle ahead. This distance
setting displays in the instrument cluster display.
Distance Setting 4 Bars (Longest)
