Elsd JEEP GRAND CHEROKEE 2023 Owners Manual

STARTING AND OPERATING133
4WD LOW To 4WD HI

With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition switch in the ON position or
the engine running, shift the transmission into
NEUTRAL (N), push and hold the 4WD LOW button
until the 4WD LOW Indicator Light begins to flash
in the instrument cluster. When the shift is
complete, the 4WD LOW Indicator Light will
remain off.

NOTE:
If shift conditions/interlocks are not met —
“4WD Shift Cancelled” or “4WD Shift Aborted/
Retry Shift” message will be displayed on the
instrument cluster. To reattempt shift, put the
transmission in NEUTRAL (N) and push and hold
the 4WD LOW button.
If shift conditions/interlocks are not met, a “To
Complete 4WD Shift Put Transmission In
Neutral” or a “To Complete 4WD Shift Speed
Must Be Below 3 MPH” or a “To Complete 4WD
Shift Allow Engine To Return To Idle” message
will flash from the instrument cluster display
Úpage 98.

Shifting into or out of 4WD LOW is possible with
the vehicle completely stopped; however, diffi -
culty may occur due to the mating clutch teeth
not being properly aligned. Several attempts
may be required for clutch teeth alignment and shift completion to occur. The preferred
method is with the vehicle rolling 0 to 3 mph
(0 to 5 km/h). If the vehicle is moving faster
than 3 mph (5 km/h), the transfer case will not
allow the shift.

QUADRA-TRAC II SYSTEM —
I
F EQUIPPED
The Quadra-Trac II System features two torque
transfer couplings. The couplings include an
Electronic Limited-Slip Differential (ELSD) rear axle
and the Quadra-Trac II transfer case. The ELSD
axle is fully automatic and requires no driver input
to operate. Under normal driving conditions, the
unit functions as a standard axle, balancing torque
evenly between left and right wheels. With a
traction difference between left and right wheels,
the coupling will sense a speed difference. As one
wheel begins to spin faster than the other, torque
will automatically transfer from the wheel that has
less traction, to the wheel that has traction. While
the transfer case and axle coupling differ in design,
their operation is similar. Follow the Quadra-Trac II
transfer case shifting information, preceding this
section, for shifting this system.
ELECTRONIC SWAY BAR DISCONNECT —
I
F EQUIPPED
Your vehicle may be equipped with an electronic
disconnecting stabilizer/sway bar. This system
allows greater front suspension travel in off-road
situations.
This system is controlled by the SWAY BAR switch
located on the instrument panel (to the right of the
gear selector).
