LIMITED SLIP DIFFERENTIAL

(IF EQUIPPED)

This axle provides added traction on

slippery surfaces, particularly when one

wheel is on a poor traction surface. Under

normal conditions, the limited-slip axle

functions like a standard rear axle. The axle

may exhibit a slight noise or vibration

during tight turns with low vehicle speed.

This is normal behavior and indicates the

axle is working.

ELECTRONIC LOCKING

DIFFERENTIAL (IF EQUIPPED)

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.

The electronic locking differential is a

device housed in the rear axle that allows

both rear wheels 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 differential operating

speed range. The differential is for use in

mud, rocks, sand, or any off-road condition

where you need maximum traction. It is

not for use on dry pavement.

The following conditions will affect the

electronic locking differential:

• The electronic locking differential will

not engage if your vehicle speed is

above 20 mph (32 km/h) in 4x2, 4x4

Auto, or 4x4 High modes

• The electronic locking differential will

not engage if your vehicle speed is

above or 56 mph (90 km/h) in 4X4

Low

• The electronic locking differential will

not engage if you press your

accelerator pedal beyond 50% during

an engagement attempt

• In 4x2, 4x4 Auto, and 4x4 High modes,

the electronic locking differential will

automatically disengage at speeds

above 25 mph (41 km/h) and will

automatically reengage at speeds

below 20 mph (32 km/h)

• In 4L (4X4 low), the electronic locking

differential will automatically

disengage at speeds above 62 mph

(100 km/h) and will automatically

reengage at speeds below 56 mph (90

km/h)

• The AdvanceTrac system has the

ability to take over control of the

electronic locking differential and

disable it during driving maneuvers

when necessary

When you switch the system on, if you do

not meet the required conditions for

electronic locking differential activation,

the instrument cluster will display the

appropriate information guiding you

through the proper activation process.

Activating the Electronic Locking

Differential (If Equipped)

Note: Do not use electronic locking

differential on dry, hard surfaced roads.

Doing so will produce excessive noise,

vibration and increase tire wear.

Note: If the electronic locking differential

has difficulty disengaging, release the

accelerator pedal and turn the steering

wheel in the opposite direction while rolling.
