2023 JEEP GRAND CHEROKEE wheel alignment

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).

ESSAGES
When the appropriate conditions exist, a message
will appear in the instrument cluster Ú page 98.
OPERATION
The indicator lamps 1 through 5 will illuminate to
show the current position of the vehicle. Flashing
indicator lamps will show a position which the
system is working to achieve. When raising, if
multiple indicator lamps are flashing while raising,
the highest flashing indicator lamp is the position
the system is working to achieve. When lowering, if
multiple indicators are flashing while lowering, the
lowest solid indicator lamp is the position the
system is working to achieve.
Toggle up once will move the suspension one
position higher from the current position,
assuming all conditions are met (i.e. ignition on,
speed below threshold, etc). Toggle up can be
pushed multiple times. Each toggle up will raise
the requested level by one position up to a
maximum position of OR2 or the highest position
allowed based on current conditions (i.e. vehicle
speed, etc).
Toggle down once will move the suspension one
position lower from the current level, assuming all
conditions are met (i.e. ignition on, doors closed,
speed below threshold, etc). Toggle down can be
WARNING!

FUEL SAVER TECHNOLOGY 5.7L ONLY —
IF EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and cruise conditions. The system
is automatic with no driver inputs or additional
driving skills required.
NOTE:This system may take some time to return to full
functionality after a battery disconnect.
POWER STEERING
The electric power steering system provides
enhanced vehicle response and increased ease of
maneuverability in tight spaces. The power
steering system adapts to different driving
conditions. If the electric power steering system
experiences a fault that prevents it from providing
assistance, you will still have the ability to steer the
vehicle manually.
NOTE:Alternate electric power steering efforts (Normal,
Comfort and Sport) can be selected through the
Uconnect System Ú page 204. If SPORT mode is
selected, steering efforts are optimized for sporty
driving.
If the Electric Power Steering warning
icon is displayed and the “Service Power
Steering” or the “Power Steering Assist
Off – Service System” message is
displayed within the instrument cluster display,
this indicates the vehicle needs to be taken to the
dealer for service Ú page 108.
NOTE:
Even if the power steering assistance is no
longer operational, it is still possible to steer the
vehicle. Under these conditions there will be a
substantial increase in steering effort, espe -
cially at low speeds and during parking maneu -
vers.
If the condition persists, see an authorized
dealer for service.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.
