2. Firmly apply the parking brake.
3. Start the engine.
4. Press and hold the brake pedal.
5. Shift the transmission into NEUTRAL. 6. Using a ballpoint pen or similar object,
push and hold the recessed transfer case
NEUTRAL (N) button (located by the se-
lector switch) for one second.

Quadra-Drive II System — If Equipped
The optional Quadra-Drive II System features
two torque transfer couplings. The couplings
include an Electronic Limited-Slip Differen-
tial (ELSD) rear axle and the Quadra-Trac II
transfer case. The optional ELSD axle is fully
automatic and requires no driver input to
operate. Under normal driving conditions,
the unit functions as a standard axle, balanc-
ing 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 auto-
matically 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 shift-
ing information, preceding this section, for
shifting this system.

• The ACC system applies the brake down toa full stop when following a target vehicle.
If an ACC host vehicle follows a target
vehicle to a standstill, the host vehicle will
release the vehicle brakes two seconds
after coming to a full stop.
• The ACC system maintains set speed when driving up hill and down hill. However, a
slight speed change on moderate hills is
normal. In addition, downshifting may oc-
cur while climbing uphill or descending
downhill. This is normal operation and
necessary to maintain set speed. When
driving up hill and down hill, the ACC
system will cancel if the braking tempera-
ture exceeds normal range (overheated).
To Increase Speed
While ACC is set, you can increase the set
speed by pushing the SET +button.
The drivers preferred units can be selected
through the instrument panel settings if
equipped. Refer to “Getting To Know Your
Instrument Panel” in the Owner’s Manual at www.jeep.com/en/owners/manuals/ for more
information. The speed increment shown is
dependant on the speed of U.S. (mph) or
Metric (km/h) units:
U.S. Speed (mph)
• Pushing the SET
+button once will result
in a 1 mph increase in set speed. Each
subsequent tap of the button results in an
increase of 1 mph.
• If the button is continually pushed, the set speed will continue to increase in 5 mph
increments until the button is released.
The increase in set speed is reflected in
the instrument cluster display.
Metric Speed (km/h)
• Pushing the SET +button once will result
in a 1 km/h increase in set speed. Each
subsequent tap of the button results in an
increase of 1 km/h.
• If the button is continually pushed, the set speed will continue to increase in 10 km/h
increments until the button is released.
The increase in set speed is reflected in
the instrument cluster display.
To Decrease Speed
While ACC is set, the set speed can be de-
creased by pushing the SET -button.
The drivers preferred units can be selected
through the instrument panel settings if
equipped. Refer to “Getting To Know Your

WARNING!
Adaptive Cruise Control (ACC) is a conve-
nience system. It is not a substitute for
active driving involvement. It is always the
driver’s responsibility to be attentive of
road, traffic, and weather conditions, ve-
hicle speed, distance to the vehicle ahead;
and, most importantly, brake operation to
ensure safe operation of the vehicle under
all road conditions. Your complete atten-
tion is always required while driving to
maintain safe control of your vehicle. Fail-
ure to follow these warnings can result in a
collision and death or serious personal
injury.
The ACC system:
• Does not react to pedestrians, oncoming vehicles, and stationary objects (e.g., a
WARNING!
stopped vehicle in a traffic jam or a
disabled vehicle).
• Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance con-
ditions.
• Does not always fully recognize complex
driving conditions, which can result in
wrong or missing distance warnings.
• Will bring the vehicle to a complete stop
while following a target vehicle and hold
the vehicle for 2 seconds in the stop
position. If the target vehicle does not
start moving within two seconds the ACC
system will display a message that the
system will release the brakes and that
the brakes must be applied manually. An
audible chime will sound when the
brakes are released.
You should switch off the ACC system:
• When driving in fog, heavy rain, heavy
snow, sleet, heavy traffic, and complex
driving situations (i.e., in highway con-
struction zones).
WARNING!
• When entering a turn lane or highway offramp; when driving on roads that are
winding, icy, snow-covered, slippery, or
have steep uphill or downhill slopes.
• When towing a trailer up or down steep
slopes.
• When circumstances do not allow safe
driving at a constant speed.
The Cruise Control system has two control
modes:
• Adaptive Cruise Control mode for main-
taining an appropriate distance between
vehicles.
• Normal (fixed speed) electronic speed
control mode for cruising at a constant
preset speed. For additional informa-
tion, refer to “Normal (Fixed Speed)
Cruise Control Mode” in your Owner’s
Manual at
www.jeep.com/en/owners/manuals/
Normal (fixed speed) electronic speed con-
trol will not react to preceding vehicles. Al-
ways be aware of the mode selected.
You can change the mode by using the
Cruise Control buttons. The two control

• Clean the ParkSense sensors regularly,taking care not to scratch or damage them.
The sensors must not be covered with ice,
snow, slush, mud, dirt or debris. Failure to
do so can result in the system not working
properly. The ParkSense system might not
detect an obstacle behind the fascia/
bumper, or it could provide a false indica-
tion that an obstacle is behind the fascia/
bumper.
• Use the ParkSense switch to turn the ParkSense system OFF if objects such as
bicycle carriers, trailer hitches, etc. are
placed within 12 in (30 cm) from the rear
fascia/bumper. Failure to do so can result
in the system misinterpreting a close ob-
ject as a sensor problem, causing the
“PARKSENSE UNAVAILABLE SERVICE
REQUIRED” message to appear in the
instrument cluster display.
• ParkSense should be disabled when the liftgate is in the open position and the
vehicle is in REVERSE. An open liftgate
could provide a false indication that an
obstacle is behind the vehicle.WARNING!
• Drivers must be careful when backing upeven when using ParkSense. Always
check carefully behind your vehicle,
look behind you, and be sure to check
for pedestrians, animals, other vehicles,
obstructions, and blind spots before
backing up. You are responsible for
safety and must continue to pay atten-
tion to your surroundings. Failure to do
so can result in serious injury or death.
• Before using ParkSense, it is strongly
recommended that the ball mount and
hitch ball assembly is disconnected
from the vehicle when the vehicle is not
used for towing. Failure to do so can
result in injury or damage to vehicles or
obstacles because the hitch ball will be
much closer to the obstacle than the
rear fascia when the loudspeaker sounds
the continuous tone. Also, the sensors
could detect the ball mount and hitch
ball assembly, depending on its size and
shape, giving a false indication that an
obstacle is behind the vehicle.
CAUTION!
• ParkSense is only a parking aid and it isunable to recognize every obstacle, in-
cluding small obstacles. Parking curbs
might be temporarily detected or not
detected at all. Obstacles located above
or below the sensors will not be detected
when they are in close proximity.
• The vehicle must be driven slowly when
using ParkSense in order to be able to
stop in time when an obstacle is de-
tected. It is recommended that the
driver looks over his/her shoulder when
using ParkSense.
PARKSENSE FRONT AND
REAR PARK ASSIST
Sensors
The four ParkSense sensors, located in the
rear fascia/bumper, monitor the area behind
the vehicle that is within the sensors field of
view. The sensors can detect obstacles from

CAUTION!
age. 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
recreational towing.
• Before recreational towing, perform the
procedure outlined under “Shifting into
NEUTRAL (N)” to be certain that the
transfer case is fully in NEUTRAL (N).
Otherwise, internal damage will result.
• Towing this vehicle in violation of the
above requirements can cause severe
transmission and/or transfer case dam-
age. Damage from improper towing is
not covered under the New Vehicle Lim-
ited Warranty.
• Do not use a bumper-mounted clamp-on
tow bar on your vehicle. The bumper
face bar will be damaged.
Shifting Into NEUTRAL (N)
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
transfer case in the NEUTRAL (N) position
without first fully engaging the parking
brake. The transfer case NEUTRAL (N)
position disengages both the front and rear
driveshafts from the powertrain and will
allow the vehicle to roll, even if the trans-
mission is in PARK. The parking brake
should always be applied when the driver
is not in the vehicle.
Use the following procedure to prepare your
vehicle for recreational towing.
CAUTION!
It is necessary to follow these steps to be
certain that the transfer case is fully in
NEUTRAL (N) before recreational towing
to prevent damage to internal parts. 1. Bring the vehicle to a complete stop, 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.
5. Using a ballpoint pen or similar object, push and hold the recessed transfer case
NEUTRAL (N) button (located by the se-
lector switch) for four seconds. The light
behind the N symbol will blink, indicating
shift in progress. The light will stop blink-
ing (stay on solid) when the shift to NEU-
TRAL (N) is complete. A “FOUR WHEEL
DRIVE SYSTEM IN NEUTRAL” message
will appear in the instrument cluster.

6. After the shift is completed and the NEU-TRAL (N) light stays on, release the NEU-
TRAL (N) button.
7. Shift the transmission into REVERSE.
8. Release the brake pedal for five seconds and ensure that there is no vehicle
movement.
9. Press and hold the brake pedal. Shift the transmission back into NEUTRAL.
10. Firmly apply the parking brake. 11. With the transmission and transfer case
in NEUTRAL, push and hold the EN-
GINE START/STOP button until the en-
gine turns off.
12. Place the transmission gear selector in PARK. Release the brake pedal.
13. Push the ENGINE STOP/START button twice (without pressing the brake pedal),
to turn the ignition to the OFF mode.
14. Attach the vehicle to the tow vehicle using a suitable tow bar.
15. Release the parking brake.
NOTE:
• Steps 1 through 4 are requirements that must be met before pushing the NEUTRAL
(N) button, and must continue to be met
until the shift has been completed. If any
of these requirements are not met before
pushing the NEUTRAL (N) button or are
no longer met during the shift, then the
NEUTRAL (N) indicator light will flash
continuously until all requirements are
met or until the NEUTRAL (N) button is
released. • The ignition must be in the ON/RUN mode
for a shift to take place and for the position
indicator lights to be operable. If the igni-
tion is not in the ON/RUN mode, the shift
will not take place and no position indica-
tor lights will be on or flashing.
• A flashing NEUTRAL (N) position indica- tor light indicates that shift requirements
have not been met.
• 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.
Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your
vehicle for normal usage.
1. Bring the vehicle to a complete stop, leav-
ing it connected to the tow vehicle.
2. Firmly apply the parking brake.
3. Start the engine.
4. Press and hold the brake pedal.

WARNING!
A loose tire or jack thrown forward in a
collision or hard stop could endanger the
occupants of the vehicle. Always stow the
jack parts and the spare tire in the places
provided. Have the deflated (flat) tire re-
paired or replaced immediately.
Changing Procedure
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with thecone shaped end of the nut toward the
wheel. Lightly tighten the lug nuts.
WARNING!
To avoid the risk of forcing the vehicle off
the jack, do not tighten the lug nuts fully
until the vehicle has been lowered. Failure
to follow this warning may result in per-
sonal injury.
3. Lower the vehicle to the ground by turning the jack handle counterclockwise.
4. Finish tightening the lug nuts. Push down on the wrench while at the end of the handle for increased leverage. Tighten the
lug nuts in a star pattern until each nut
has been tightened twice. The correct
tightness of each lug nut is 130 ft-lbs
(176 N·m). If in doubt about the correct
tightness, have them checked with a
torque wrench by your authorized dealer
or service station.
NOTE:
For the SRT model the correct wheel nut
tightness is 110 ft lbs (149 N·m).
5. After 25 miles (40 km) check the lug nut torque with a torque wrench to ensure that
all lug nuts are properly seated against the
wheel.JUMP-STARTING
If your vehicle has a discharged battery it can
be jump-started using a set of jumper cables
and a battery in another vehicle or by using a
portable battery booster pack. Jump-starting
can be dangerous if done improperly so
please follow the procedures in this section
carefully.
WARNING!
Do not attempt jump-starting if the battery
is frozen. It could rupture or explode and
cause personal injury.
CAUTION!
Do not use a portable battery booster pack
or any other booster source with a system
voltage greater than 12 Volts or damage to
the battery, starter motor, alternator or
electrical system may occur.
NOTE:
When using a portable battery booster pack
follow the manufacturer's operating instruc-
tions and precautions.
Preparations For Jump-Starting
The battery in your vehicle is located under
the passenger's front seat. There are remote
locations located under the hood to assist in
jump-starting.

REFUELING IN EMERGENCY
The funnel for the Cap-Less Fuel System is
located in the spare tire storage area. If your
vehicle is out of fuel and an auxiliary fuel can
is needed, insert the funnel into the filler
neck and proceed to fill the vehicle.
For more information on the Cap-Less Fuel
System refer to “Refueling The Vehicle” in
“Starting And Operating ” in this manual.
IF YOUR ENGINE
OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place thetransmission in NEUTRAL, but do not in-
crease the engine idle speed while prevent-
ing vehicle motion with the brakes. NOTE:
There are steps that you can take to slow
down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it
off. The A/C system adds heat to the en-
gine cooling system and turning the A/C
off can help remove this heat.
• You can also turn the temperature control to maximum heat, the mode control to
floor and the blower control to high. This
allows the heater core to act as a supple-
ment to the radiator and aids in removing
heat from the engine cooling system.WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator or coolant
bottle is hot.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop
the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer
drops back into the normal range. If the
pointer remains on HOT (H), and you hear
continuous chimes, turn the engine off
immediately and call for service.
MANUAL PARK RELEASE
WARNING!
Always secure your vehicle by fully apply-
ing the parking brake, before activating
the Manual Park Release. Activating the
Manual Park Release will allow your ve-
hicle to roll away if it is not secured by the
parking brake or by proper connection to a
tow vehicle. Activating the Manual Park
Release on an unsecured vehicle could
lead to serious injury or death for those in
or around the vehicle.
