2013 JEEP GRAND CHEROKEE Owner handbook (in English)

•If the vehicle has not been driven for
several days, the first few seconds of
operation after shifting the transmission
into gear may seem sluggish. This is due
to the fluid partially draining from the
torque converter into the transmission.
This condition is normal and will not
cause damage to the transmission. The
torque converter will refill within five sec-
onds after starting the engine.
FOUR-WHEEL DRIVE
OPERATION
Quadra-Trac II® Operating
Instructions/Precautions
The Quadra-Trac II® transfer case is fully auto-
matic in the normal driving 4WD AUTO mode.
The Quadra-Trac II® transfer case provides
three mode positions:
•4WD HI
• NEUTRAL
• 4WD LOW This 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, slip-
pery road surfaces only. Driving in the 4WD
LOW position on dry, hard-surfaced roads may
cause increased tire wear and damage to drive-
line 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 cir-
cumference on each wheel. Any difference will
adversely affect shifting and cause damage to
the transfer case.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe
turning and stopping speeds. Do not go faster
than road conditions permit.
WARNING!
You or others could be injured if you leave
the vehicle unattended with the transfer case
in the NEUTRAL (N) position without first
fully engaging the parking brake. The trans-
fer case NEUTRAL (N) position disengages
both the front and rear driveshafts from the
powertrain and will allow the vehicle to move
regardless of the transmission position. The
parking brake should always be applied
when the driver is not in the vehicle.

Shift PositionsFor additional information on the appropriate
use of each transfer case mode position, see
the information below:
4WD AUTO
This range is used on surfaces such as ice,
snow, gravel, sand, and dry hard pavement.
NOTE:
Refer to “Selec-Terrain® – If Equipped” in
“Starting and Operating” for further infor-
mation on the various positions and their
intended usages.
NEUTRAL
This range disengages both the front and rear
driveshafts from the powertrain. It is to be used
for flat towing behind another vehicle. Refer to
“Recreational Towing” in “Starting and Operat-
ing” for further information.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
further information on the various positions
and their intended usages.
Shifting Procedures
4WD HI To 4WD LOW
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.
NOTE:
If shift conditions/interlocks are not met, or
a transfer case motor temperature protec-
tion 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 Elec-
tronic Vehicle Information Center (EVIC). Re-
fer to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument
Panel” for further information.

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 pro-
tection 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 Electronic Vehicle Information Center
(EVIC). Refer to “Electronic Vehicle Infor-
mation Center (EVIC)” in “Understanding
Your Instrument Panel” for further infor-
mation. •Shifting into or out of 4WD LOW is possible
with the vehicle completely stopped; how-
ever, difficulty 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.
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 NEU-
TRAL.
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 Informa-
tion Center (EVIC). Refer to “Electronic Ve-
hicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further
information.Neutral Switch

Quadra-Drive® II System – If
Equipped
The optional Quadra-Drive® 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 optional ELSD axle is fully
automatic and requires no driver input to oper-
ate. 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 differ-
ence. 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 sec-
tion, for shifting this system.
SELEC-TERRAIN™ — IF
EQUIPPED
DescriptionSelec-Terrain™ combines the capabilities of the
vehicle control systems, along with driver input,
to provide the best performance for all terrains.Selec-Terrain™ consists of the following posi-
tions:
•
Sport – Dry weather, on-road calibration.
Only available in 4WD High range. Perfor-
mance based tuning that provides a rear
wheel drive feel but with improved handling
and acceleration over a two-wheel drive ve-
hicle. The Electronic Stability Control will set
to allow more driver control of vehicle while
maintaining safe handling controls. The ve-
hicle will lower (if equipped with Air Suspen-
sion) to Aero Mode in High Range. 4WD Low
is not available in SPORT mode, if 4WD Low
is selected the Selec-Terrain™ will automati-
cally switch back to AUTO.
• Snow – Tuning set for additional stability in
inclement weather. Use on and off road on
loose traction surfaces such as snow. When
in Snow mode (depending on certain operat-
ing conditions), the transmission may use
second gear (rather than first gear) during
launches, to minimize wheel slippage. If
equipped with air suspension, the level will
change to Normal Ride Height (NRH) if the
transfer case is in high range. The level will
change to Off-Road 1 if the transfer case is in
Low range.
Selec-Terrain™ Switch
240

•Auto – Fully automatic full time four-wheel
drive operation can be used on and off road.
Balances traction with seamless steering feel
to provide improved handling and accelera-
tion over two-wheel drive vehicles. If
equipped with air suspension, the level will
change to NRH.
•
Sand/Mud–Off road calibration for use on low
traction surfaces such as mud, sand, or wet
grass. Driveline is maximized for traction.
Some binding may be felt on less forgiving
surfaces. The electronic brake controls are set
to limit traction control management of throttle
and wheel spin. If equipped with air suspen-
sion, the level will change to Off-Road 1.
• Rock – Off-road calibration only available in
4WD Low range. The vehicle is raised (if
equipped with Air Suspension) for improved
ground clearance. Traction based tuning with
improved steer-ability for use on high traction
off-road surfaces. Activate the Hill Descent
Control for steep downhill control. Use for low
speed obstacles such as large rocks, deep ruts, etc. If equipped with air suspension, the
vehicle level will change to Off-Road 2. If the
Selec-Terrain™ switch is in ROCK mode,
and the transfer case is switched from 4WD
Low to 4WD High, the Selec-Terrain™ sys-
tem will return to AUTO.

•Off-Road 1 (OR1) (Raises the vehicle ap-
proximately 1.3 in (33 mm) – This is the
primary position for all off-road driving until
OR2 is needed. A smoother and more com-
fortable ride will result. Press the “Up” button
once from the NRH position while the vehicle
speed is below 38 mph (61 km/h). When in
the OR1 position, if the vehicle speed re-
mains between 40 mph (64 km/h) and
50 mph (80 km/h) for greater than 20 sec-
onds or if the vehicle speed exceeds 50 mph
(80 km/h), the vehicle will be automatically
lowered to NRH. Refer to “Off-Road Driving
Tips” in “Starting and Operating” for further
information.
• Off-Road 2 (OR2) (Raises the vehicle ap-
proximately 2.6 in (65 mm) – This position
is intended for off-roading use only where
maximum ground clearance is required. To
enter OR2, press the “Up” button twice from
the NRH position or once from the OR1
position while vehicle speed is below 20 mph
(32 km/h). While in OR2, if the vehicle speed exceeds 25 mph (40 km/h) the vehicle height
will be automatically lowered to OR1. Refer
to “Off-Road Driving Tips” in “Starting and
Operating” for further information.
• Aero Mode (Lowers the vehicle approxi-
mately 0.5 in (13 mm) – This position pro-
vides improved aerodynamics by lowering
the vehicle. The vehicle will automatically
enter Aero Mode when the vehicle speed
remains between 62 mph (99 km/h) and
66 mph (106 km/h) for greater than 20 sec-
onds or if the vehicle speed exceeds 66 mph
(106 km/h). The vehicle will return to NRH
from Aero Mode if the vehicle speed remains
between 30 mph (48 km/h) and 35 mph
(56 km/h) for greater than 20 seconds or if
the vehicle speed falls below 30 mph
(48 km/h). The vehicle will enter Aero Mode,
regardless of vehicle speed if the Selec-
Terrain™ knob is turned to the “SPORT”
position. Turning the Selec-Terrain™ knob to
the “AUTO” position will return the system to
normal operation. •
Park Mode (Lowers the vehicle approxi-
mately 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 sec-
onds, 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 suspen-
sion buttons. Refer to “Selec-Terrain™” in “Start-
ing 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 oncom-
ing 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.
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 ap-
pearance.
To assist with changing a spare tire, the
Quadra-Lift™ air suspension system has a fea-
ture which allows the automatic 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 immediatelyafter 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 suspension 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 pres-
sure volume of air to operate the system. To
avoid personal injury or damage to the sys-
tem, see your authorized dealer for service.

in “Understanding Your Instrument Panel” for
further information.
An audible chime will be heard whenever a
system error has been detected.
OperationThe indicator lamps 3 through 6 will illuminate to
show the current position of the vehicle. Flash-
ing 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 indicator lamp
is the position the system is working to achieve.
When lowering, if multiple indicators are flash-
ing on the
"Up"button the lowest solid indicator
lamp is the position 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 con-
ditions (i.e. vehicle speed, etc).
243

Pressing the “DOWN” button once will move the
suspension one position lower from the current
level, assuming all conditions are met (i.e. en-
gine 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. ve-
hicle 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.
• Normal Ride Height (NRH) – Indicator lamp 4
will be illuminated when the vehicle is in this
position. •
Park Mode – Indicator lamp 3 will be illumi-
nated 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 indica-
tor 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 applica-
tions. 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 sat-
isfactorily in off-road conditions. If at all pos-
sible, 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.
