2013 JEEP GRAND CHEROKEE engine

ABS and Traction Control, provides resistance to any
wheel that is slipping to allow additional torque transfer
to wheels with traction.
NOTE:The Quadra-Trac I® system is not appropriate
for conditions where 4WD LOW range is recommended.
Refer to “Off-Road Driving Tips” in “Starting and Oper-
ating” for further information.
Quadra-Trac II® Operating Instructions/
Precautions – If Equipped
The Quadra-Trac II® transfer case is fully automatic in
the normal driving 4WD AUTO mode. The Quadra-Trac
II® transfer case provides three mode positions:
•4WD HI
•NEUTRAL
•4WD LOWThis transfer case is fully automatic in the 4WD HI mode.
When additional traction is required, the 4WD LOW
position can be used to lock the front and rear driveshafts
together and force the front and rear wheels to rotate at
the same speed. The 4WD LOW position is intended for
loose, slippery road surfaces only. Driving in the 4WD
LOW position on dry, hard-surfaced roads may cause
increased tire wear and damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 4WD HI
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.
468 STARTING AND OPERATING

4WD LOW
This range is for low speed four-wheel drive. It locks the
front and rear driveshafts together and forces the front
and rear wheels to rotate at the same speed. It provides
additional traction and maximum pulling power for
loose, slippery road surfaces only. Do not exceed 25 mph
(40 km/h).
NOTE:Refer to “Selec-Terrain® – If Equipped” for fur-
ther information on the various positions and their
intended usages.
Shifting Procedures
4WDHITo4WDLOW
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, and press the
“4WD LOW” button once on the transfer case switch.The “4WD LOW” indicator light in the instrument cluster
will begin to flash and remain on solid when the shift is
complete.Transfer Case Switch
470 STARTING AND OPERATING

NOTE:If shift conditions/interlocks are not met, or a
transfer case motor temperature protection condition
exists, a “For 4x4 Low Slow Below 3 MPH or 5 KPH Put
Trans in N Press 4 Low” message will flash from the
Electronic Vehicle Information Center (EVIC). Refer to
“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.
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, and press the
“4WD LOW” button once on the transfer case switch. The
“4WD LOW” indicator light in the instrument cluster
will flash and go out when the shift is complete.NOTE:
•If shift conditions/interlocks are not met, or a transfer
case motor temperature protection condition exists, a
“For 4x4 High Slow Below 3 MPH or 5 KPH Put Trans
in N Press 4 Low” message will flash from the Elec-
tronic Vehicle Information Center (EVIC). Refer to
“Electronic Vehicle Information Center (EVIC)” in
“Understanding Your Instrument Panel” for further
information.
•Shifting into or out of 4WD LOW is possible with the
vehicle completely stopped; however, difficulty may
occur due to the mating clutch teeth not being prop-
erly 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.5

NEUTRAL Shift Procedure
1. Turn the ignition switch to the ON position, engine off.
2. Vehicle stopped, with foot on brake.
3. Place the transmission into NEUTRAL.
4. Hold down the NEUTRAL “pin” switch (with a pen,
etc.) for four seconds until the LED light by the switch
starts to blink indicating shift in progress. The light
will stop blinking (stay on solid) when the NEUTRAL
shift is complete.
5. Repeat Steps 1 to 4 to shift out of NEUTRAL.
NOTE:If shift conditions/interlocks are not met, a “To
Tow Vehicle Safely, Read Neutral Shift Procedure in
Owners Manual” message will flash from the Electronic
Vehicle Information Center (EVIC). Refer to “Electronic
Vehicle Information Center (EVIC)” in “Understanding
Your Instrument Panel” for further information.
Neutral Switch
472 STARTING AND OPERATING

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.

Display Messages
When the appropriate conditions exist, a message will
appear in the EVIC display. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
An audible chime will be heard whenever a system error
has been detected.5
STARTING AND OPERATING 479

Operation
The indicator lamps 3 through 6 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 on the “Up” button, the highest flashing indica-
tor lamp is the position the system is working to achieve.
When lowering, if multiple indicators are flashing on the
Upbutton the lowest solid indicator lamp is the posi-
tion the system is working to achieve.
Pressing the “UP” button once will move the suspension
one position higher from the current position, assuming
all conditions are met (i.e. engine running, speed below
threshold, etc). The “UP” button can be pressed multiple
times, each press 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).Pressing the “DOWN” button once will move the sus-
pension one position lower from the current level, as-
suming all conditions are met (i.e. engine running, doors
closed, speed below threshold, etc). The “DOWN” button
can be pressed multiple times. Each press will lower the
requested level by one position down to a minimum of
Park Mode or the lowest position allowed based on
current conditions (i.e. vehicle speed, etc.)
Automatic height changes will occur based on vehicle
speed and the current vehicle height. The indicator lamps
and EVIC messages will operate the same for automatic
changes and user requested changes.
•Off-Road 2 (OR2) – Indicator lamps 4, 5, and 6 will be
illuminated when the vehicle is in OR2.
•Off-Road 1 (OR1) – Indicator lamps 4 and 5 will be
illuminated when the vehicle is in OR1.
480 STARTING AND OPERATING

•Normal Ride Height (NRH) – Indicator lamp 4 will be
illuminated when the vehicle is in this position.
•
Park Mode – Indicator lamp 3 will be illuminated when
the vehicle is in Park Mode. If Park Mode is requested
while vehicle speed is between 15 mph (24 km/h) and
25 mph (40 km/h), indicator lamp 4 will remain on solid
and indicator lamp 3 will flash as the system waits for the
vehicle to reduce speed. If vehicle speed is reduced to,
and kept below, 15 mph (24 km/h) indicator lamp 4 will
turn off and indicator lamp 3 will flash until Park Mode is
achieved at which point indicator lamp 3 will go solid. If
during the height change to Park Mode, the vehicle speed
exceeds 15 mph (24 km/h), the height change will be
paused until the vehicle speed either goes below 15 mph
(24 km/h) and the height change continues to Park Mode,
or exceeds 25 mph (40 km/h) and the vehicle height will
return to NRH. Park Mode may be selected while the
vehicle is not moving provided that the engine is still
running and all doors remain closed.
ON-ROAD DRIVING TIPS
Utility vehicles have higher ground clearance and a
narrower track to make them capable of performing in a
wide variety of off-road applications. Specific design
characteristics give them a higher center of gravity than
ordinary cars.
An advantage of the higher ground clearance is a better
view of the road, allowing you to anticipate problems.
They are not designed for cornering at the same speeds as
conventional two-wheel drive vehicles any more than
low-slung sports cars are designed to perform satisfacto-
rily in off-road conditions. If at all possible, avoid sharp
turns or abrupt maneuvers. As with other vehicles of this
type, failure to operate this vehicle correctly may result in
loss of control or vehicle rollover.
