2023 JEEP GRAND CHEROKEE air suspension

STARTING AND OPERATING197
Shifting Into Transfer Case N (NEUTRAL)
Use the following procedure to prepare your
vehicle for recreational towing:

1. Bring the vehicle to a complete stop on level
ground, with the engine running.

2. Press and hold the brake pedal.
3. Shift the transmission into NEUTRAL. 4. If vehicle is equipped with Quadra-Lift air
suspension, ensure the vehicle is set to
Normal Ride Height with the Auto Entry/Exit
setting deselected.
NOTE:
Steps 1 through 4 are requirements that
must be met before pushing the N
(NEUTRAL) button, and must continue to be
met until the shift has been completed. If
any of these requirements are not met
before pushing the N (NEUTRAL) button or
are no longer met during the shift, then the
N (NEUTRAL) indicator light will flash contin -
uously until all requirements are met or until
the N (NEUTRAL) button is released.
The ignition must be in the ON/RUN position
for a shift to take place and for the position
indicator lights to be operable. If the ignition
is not in the ON/RUN position, the shift will
not take place and no position indicator
lights will be on or flashing.
A flashing N (NEUTRAL) position indicator
light indicates that shift requirements have
not been met.
CAUTION!
DO NOT dolly tow any 4WD vehicle. Towing
with only one set of wheels on the ground
(front or rear) will cause severe transmission
and/or transfer case damage. Tow with all
four wheels either ON the ground, or OFF the
ground (using a vehicle trailer).
Tow only in a forward direction. Towing this
vehicle backwards can cause severe damage
to the transfer case.
The transmission must be in PARK for recre -
ational towing.
Before recreational towing, perform the proce -
dure outlined under “Shifting into N
(NEUTRAL)” to be certain that the transfer
case is fully in N (NEUTRAL). Otherwise,
internal damage will result.
Towing this vehicle in violation of the above
requirements can cause severe transmission
and/or transfer case damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
Do not use a bumper-mounted clamp-on tow
bar on your vehicle. The bumper face bar will
be damaged.
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the N (NEUTRAL) position without first
fully engaging the Electric Park Brake. The
transfer case N (NEUTRAL) position disengages
both the front and rear driveshafts from the
powertrain and will allow the vehicle to roll, even
if the transmission is in PARK. The Electric Park
Brake should always be applied when the driver
is not in the vehicle.
CAUTION!
It is necessary to follow these steps to be certain
that the transfer case is fully in N (NEUTRAL)
before recreational towing to prevent damage to
internal parts.

198STARTING AND OPERATING
If the vehicle is equipped with Quadra-Lift
air suspension, the engine should be
started and left running for a minimum of
60 seconds (with all the doors closed) at
least once every 24 hours. This process
allows the air suspension to adjust the
vehicle’s ride height to compensate for
temperature effects.
Engaging/disengaging of the Electric Park
Brake requires the ignition to be in the ON/
RUN position.
If shift conditions/interlocks are not met, a
“4WD Shift Canceled” or a “4WD Shift
Aborted/ Retry Shift” message will be
displayed on the instrument cluster. To reat -
tempt 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

Complete 4WD Shift Allow Engine To Return
To Idle” message will flash from the instru -
ment cluster display Ú page 98.
5. Using a ballpoint pen or similar object, push and hold the recessed transfer case N
(NEUTRAL) button (located by the selector
switch) for more than four seconds. The light
behind the N symbol will blink, indicating shift in progress. The light will stop blinking (stay on
solid) when the shift to N (NEUTRAL) is
complete. A “Four Wheel Drive System In
Neutral” message will appear in the
instrument cluster.

200STARTING AND OPERATING
OFF-ROAD DRIVING TIPS
Quadra-Lift — If Equipped
When off-roading, it is recommended that the
lowest useable vehicle height that will clear the
current obstacle or terrain be selected. The vehicle
height should then be raised as required by the
changes in terrain.
The Selec-Terrain switch will automatically change
the vehicle to the optimized height based on the
Selec-Terrain switch position. The vehicle height
can be changed from the default height for each
Selec-Terrain mode by normal use of the air
suspension switches Úpage 131.
When To Use 4WD LOW Range —
If Equipped
When off-road driving, shift to 4WD LOW for
additional traction. This range should be limited to
extreme situations such as deep snow, mud, or
sand where additional low speed pulling power is
needed. Vehicle speeds in excess of 25 mph
(40 km/h) should be avoided when in 4WD LOW
range.
Driving Through Water
Although your vehicle is capable of driving through
water, there are a number of precautions that
must be considered before entering the water.
NOTE:Your vehicle is capable of water fording in up to
24 inches (61 cm) with air suspension or
21 inches (53 cm) without air suspension, of water
while crossing small rivers or streams. To maintain
optimal performance of your vehicle's heating and
ventilation system it is recommended to switch the
system into recirculation mode during water
fording. Be sure to avoid lowering the vehicle in
water, ensure that the easy exit entry setting is
turned off in Uconnect settings. Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your vehicle.
If you must drive through water, try to determine
the depth and the bottom condition (and location
of any obstacles) prior to entering. Proceed with
caution and maintain a steady controlled speed
less than 5 mph (8 km/h) in deep water to
minimize wave effects.
Flowing Water
If the water is swift flowing and rising (as in storm
run-off), avoid crossing until the water level
recedes and/or the flow rate is reduced. If you
must cross flowing water avoid depths in excess of
9 inches (23 cm). The flowing water can erode the
streambed, causing your vehicle to sink into
deeper water. Determine exit point(s) that are
downstream of your entry point to allow for drifting.
WARNING!
Do not drive in 4WD LOW range on dry
pavement; driveline damage may result. 4WD
LOW range locks front and rear drivelines
together and does not allow for differential
action between the front to rear driveshafts.
Driving in 4WD LOW on pavement will cause
driveline binding; use only on wet or slippery
surfaces.
CAUTION!
When driving through water, do not exceed
5 mph (8 km/h). Always check water depth
before entering as a precaution, and check all
fluids afterward. Driving through water may
cause damage that may not be covered by the
New Vehicle Limited Warranty.

23_WL_OM_EN_USC_t.book Page 200

STARTING AND OPERATING201
Standing Water
Avoid driving in standing water deeper than
24 inches (61 cm) with air suspension or
21 inches (53 cm) without air suspension, and
reduce speed appropriately to minimize wave
effects. Maximum speed is 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your
vehicle fluids and lubricants (engine oil,
transmission oil, axle, transfer case) to ensure the
fluids have not been contaminated. Contaminated
fluid (milky, foamy in appearance) should be
flushed/changed as soon as possible to prevent
component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for
additional control at slower speeds, shift the
transmission to a low gear and shift the transfer
case to 4WD LOW if necessary Ú page 131. Only
shift into a lower gear to maintain forward motion.
Over-revving the engine can spin the wheels and
traction will be lost.
Avoid abrupt downshifts on icy or slippery roads,
because engine braking may cause skidding and
loss of control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission
to a lower gear and shift the transfer case to 4WD
LOW. Use FIRST gear and 4WD LOW for very steep
hills.
If you stall or begin to lose forward motion while
climbing a steep hill, allow your vehicle to come to
a stop and immediately apply the brakes. Restart
the engine, and shift into REVERSE (R). Back slowly
down the hill, allowing the compression braking of
the engine to help regulate your speed. If the
brakes are required to control vehicle speed, apply
them lightly and avoid locking or skidding the tires. Remember, never drive diagonally across a hill.
Always drive straight up or down.
If the wheels start to slip as you approach the crest
of a hill, ease off the accelerator and maintain
forward motion by turning the front wheels slowly.
This may provide a fresh “bite” into the surface and
will usually provide traction to complete the climb.
Traction Downhill
When descending mountains or hills, use Hill
Descent Control or Selec-Speed Control to avoid
repeated heavy braking.
If not equipped with Hill Descent Control or
Selec-Speed Control use the following procedure:
Shift the transmission into a low gear, and the
transfer case into 4WD LOW range. Let the vehicle
go slowly down the hill with all four wheels turning
against engine compression drag. This will permit
you to control the vehicle speed and direction.
When descending mountains or hills, repeated
braking can cause brake fade with loss of braking
control. Avoid repeated heavy braking by
downshifting the transmission whenever possible.
WARNING!
If the engine stalls, you lose forward motion, or
cannot make it to the top of a steep hill or grade,
never attempt to turn around. To do so may
result in tipping and rolling the vehicle. Always
back carefully straight down a hill in REVERSE
gear. Never back down a hill in NEUTRAL using
only the brake.

RADIO OPERATION AND MOBILE PHONES
Under certain conditions, the mobile phone being
on in your vehicle can cause erratic or noisy
performance from your radio. This condition may
be lessened or eliminated by repositioning the
mobile phone within the vehicle. This condition is
not harmful to the radio. If your radio performance
does not satisfactorily improve from repositioning the mobile phone, it is recommended that the
volume be turned down or off during mobile phone
operation when not using the Uconnect system.
