WHAT IS THE ELECTRONIC
LOCKING DIFFERENTIAL
The electronic locking differential is a
device housed in the rear axle, and when
activated, allows both wheels on a specific
axle to turn at the same speed. The
electronic locking differential can provide
additional traction should your vehicle
become stuck. You can activate the
differential electronically and shift it on the
fly within the operating speed range. The
electronic differential will disengage when
the vehicle speed exceeds a set value and
it will reengage when the vehicle speed
goes below a set value. See Switching
the Electronic Locking Differential On
and Off (page 269). It will also engage
based on certain selected drive modes.
See Selecting a Drive Mode (page 328).
The electronic locking differential is for use
in mud, rocks, sand, or any off-road
condition where you need maximum
traction.
Note: The electronic locking differential is
for off-road use only and is not for use on
dry pavement. Using the electronic locking
differential on dry pavement will result in
increased tire wear, noise and vibration.
ELECTRONIC LOCKING
DIFFERENTIAL PRECAUTIONS
Operating the Electronic Locking
Differential with a Spare or
Mismatched Tires
On vehicles with an electronic locking
differential, the size of the spare tire can
affect performance of the system. If there
is a significant difference between the two
rear tires, you may have limited electronic
locking differential functionality. If the
system has difficulty disengaging, release
the accelerator pedal and turn the steering
wheel in the opposite direction when
rolling. We recommend engaging and
disengaging the electronic locking
differential at a stop when you mount a
spare on the rear axle.
SWITCHING THE ELECTRONIC
LOCKING DIFFERENTIAL ON
AND OFF - 4X4
The button to activate and deactivate the
electronic locking differential is in the
center of the drive mode rotary switch.
