vehicle for normal usage.
1. Bring the vehicle to a complete stop.
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.
7. When the NEUTRAL (N) indicator light turns off, release the NEUTRAL (N)
button.
8. After the NEUTRAL (N) button has been released, the transfer case will shift to the
position indicated by the selector 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 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
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 decrease in set speed. Each
subsequent tap of the button results in a
decrease of 1 mph.
• If the button is continually pushed, the set speed will continue to decrease in 5 mph
decrements until the button is released.
The decrease in set speed is reflected in
the instrument cluster display.
STARTING AND OPERATING

79 inches (200 cm) from the rear fascia/
bumper in the horizontal direction, depend-
ing on the location, type and orientation of
the obstacle.
The six ParkSense sensors, located in the
front fascia/bumper, monitor the area in front
of the vehicle that is within the sensors’ field
of view. The sensors can detect obstacles
from approximately 12 inches (30 cm) up to
47 inches (120 cm) from the front fascia/
bumper in the horizontal direction, depend-
ing on the location, type and orientation of
the obstacle.
When an object is detected within 79 inches
(200 cm) behind the rear bumper while the
vehicle is in REVERSE, a warning will appear
in the instrument cluster display. In addition
a chime will sound (when Sound and Display
is selected from the Customer Programmable
Features section of the Uconnect System
screen). As the vehicle moves closer to the
object, the chime rate will change from single
1/2 second tone (for rear only), to slow (for
rear only), to fast, to continuous.Activation/Deactivation
The ParkSense Park Assist system provides
visual and audible indications of the distance
between the rear and/or front fascia and a
detected obstacle when backing up or moving
forward, e.g. during a parking maneuver. If
your vehicle is equipped with an Automatic
Transmission, the vehicle brakes may be au-
tomatically applied and released when per-
forming a reverse parking maneuver if the
system detects a possible collision with an
obstacle.
ParkSense can be active only when the gear
selector is in REVERSE or DRIVE. If
ParkSense is enabled at one of these gear
selector positions, the system will remain
active until the vehicle speed is increased to
approximately 7 mph (11 km/h) or above. A
display warning will appear in the instrument
cluster display indicating the vehicle is above
ParkSense operating speed. The system will
become active again if the vehicle speed is
decreased to speeds less than approximately
6 mph (9 km/h).
Engagement/Disengagement
To disengage the system, push the ParkSense
switch, located on the switch panel below the
Uconnect display.
When the system passes from engaged to
disengaged and vice versa, it is always ac-
companied by a dedicated message in the
instrument cluster display.
System engaged:ParkSense switch LED off.
System disengaged: ParkSense switch LED on
constantly.
The ParkSense switch LED lights up also in
the case of a ParkSense system failure. If the
button is pushed with a system failure, the
ParkSense switch LED flashes for about
5 seconds, then it stays on constantly.
After the ParkSense has been disengaged, it
will stay in this condition until the following
engagement, even if the ignition device
passes from ON/RUN to OFF and then again
to ON/RUN.

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

SCHEDULED SERVICING
NON-SRT
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is
time to take your vehicle in for scheduled
maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate.
This means that service is required for your
vehicle. Operating conditions such as fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel
usage will influence when the “Oil Change
Required” message is displayed. Severe op-erating conditions can cause the change oil
message to illuminate as early as
3,500 miles (5,600 km) since last reset.
Have your vehicle serviced as soon as pos-
sible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
twelve months or 350 hours of engine run
time, whichever comes first. The 350 hours
of engine run or idle time is generally only a
concern for fleet customers. Once A Month Or Before A Long Trip:
• Check engine oil level.
• Check windshield washer fluid level.
• Check the tire inflation pressures and look
for unusual wear or damage.
• Check the fluid levels of the coolant reser- voir, brake master cylinder and fill as
needed.
• Check function of all interior and exterior lights
Required Maintenance
Refer to the Maintenance Schedules on the
following pages for required maintenance.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
• Change oil and filter.
• Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
• Inspect battery and clean and tighten terminals as required.
• Inspect brake pads, shoes, rotors, drums, hoses and park brake.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or off-road conditions.SERVICING AND MAINTENANCE
