2013 JEEP GRAND CHEROKEE air suspension

Selec-Terrain™ knob is turned to the “SPORT” posi-
tion. Turning the Selec-Terrain™ knob to the “AUTO”
position will return the system to normal operation.
•Park Mode (Lowers the vehicle approximately 1.5 in
(38 mm)– This position lowers the vehicle for easier
passenger entry and exit as well as lowering the rear of
the vehicle for easier loading and unloading of cargo.
To enter Park Mode, press the “Down” button once
while the vehicle speed is below 25 mph (40 km/h).
Once the vehicle speed goes below 15 mph (24 km/h)
the vehicle height will begin to lower. If the vehicle
speed remains between 15 mph (24 km/h) and 25 mph
(40 km/h) for greater than 60 seconds, or the vehicle
speed exceeds 25 mph (40 km/h) the Park Mode
change will be cancelled. To exit Park Mode, press the
“Up” button once while in Park Mode or drive the
vehicle over 15 mph (24 km/h).The Selec-Terrain™ switch will automatically change the
vehicle to the proper height based on the position of the
Selec-Terrain™ switch. The height can be changed from
the default Selec-Terrain™ setting by normal use of the
air suspension buttons. Refer to “Selec-Terrain™” in
“Starting and Operating” for further information.
The system requires that the engine be running for all
changes. When lowering the vehicle all of the doors,
including the liftgate, must be closed. If a door is opened
at any time while the vehicle is lowering the change will
not be completed until the open door(s) is closed.
The Quadra-Lift™ air suspension system uses a lifting
and lowering pattern which keeps the headlights from
incorrectly shining into oncoming traffic. When raising
the vehicle, the rear of the vehicle will move up first and
then the front. When lowering the vehicle, the front will
move down first and then the rear.
478 STARTING AND OPERATING

After the engine is turned off, it may be noticed that the
air suspension system operates briefly, this is normal. The
system is correcting the position of the vehicle to ensure
a proper appearance.
To assist with changing a spare tire, the Quadra-Lift™ air
suspension system has a feature which allows the auto-
matic leveling to be disabled. Press and hold both the
“Up” and “Down” buttons simultaneously between 5
and 10 seconds, a message will appear in the EVIC
stating leveling has been disabled immediately after both
buttons have been released. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information. Driving the
vehicle over 5 mph (8 km/h) will return the air suspen-
sion to normal operation. Refer to “Jacking and Tire
Changing” in “What To Do In Emergencies” for further
information.WARNING!
The air suspension system uses a high pressure
volume of air to operate the system. To avoid per-
sonal injury or damage to the system, see your
authorized dealer for service.
Electronic Vehicle Information Center (EVIC)
Display Messages

appear in the EVIC display. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.

has been detected.5
STARTING AND OPERATING 479

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. Refer
to “Quadra-Lift™ – If Equipped” in “Starting and Oper-
ating” for further information.
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 situa-
tions such as deep snow, mud, or sand where additionallow speed pulling power is needed. Vehicle speeds in
excess of 25 mph (40 km/h) should be avoided when in
4WD LOW range.
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 andcrow-hop; use only on
wet or slippery surfaces.
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.
