Five-Position Transfer Case
The transfer case provides five mode posi-
tions:
• 2H (Two-Wheel Drive High Range)
•
4H Auto (Four-Wheel Drive Auto High Range)
• 4H PT (Four-Wheel Drive Part Time High
Range)
• N (Neutral)
• 4L (Four-Wheel Drive Low Range)For additional information on the appropriate
use of each transfer case mode position, see
the information below:
2H
Rear Wheel Drive High Range — This range is
for normal street and highway driving on dry,
hard surfaced roads.
4H AUTO
Four-Wheel Drive Auto High Range — This
range sends power to the front wheels. The
four-wheel drive system will be automatically
engaged when the vehicle senses a loss of
traction. Additional traction for varying road
conditions.
4H P-T
Four-Wheel Drive Part Time High Range —
This range maximizes torque to the front
driveshaft, forcing the front and rear wheels
to rotate at the same speed. This range pro-
vides additional traction for loose, slippery
road surfaces only.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 auto-
matic transmission is in PARK. The park-
ing brake should always be applied when
the driver is not in the vehicle.
Neutral — This range disengages both the
front and rear driveshafts from the pow-
ertrain. To be used for flat towing behind
another vehicle.
Refer to “Recreational Towing” in “Starting
And Operating” for further information.
4L
Four-Wheel Drive Low Range — This range
provides low speed four-wheel drive. It maxi-
mizes torque to the front driveshaft, forcing
the front and rear wheels to rotate at the same

• When you turn ParkSense OFF, the instru-
ment cluster display will read
“PARKSENSE OFF.” Furthermore, once
you turn ParkSense OFF, it remains off until
you turn it on again, even if you cycle the
ignition.
• ParkSense, when on, will reduce the vol-
ume of the radio when it is sounding a tone.
• Clean the ParkSense sensors regularly, tak-
ing 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 inches (30 cm) from the
rear fascia/bumper. Failure to do so can
result in the system misinterpreting a close
object as a sensor problem, causing the“PARKSENSE UNAVAILABLE SERVICE
REQUIRED” message to be displayed in
the instrument cluster display.
• The operation of the rear sensors is auto-
matically deactivated when the trailer's
electric plug is inserted in the vehicle's tow
hook socket. The rear sensors are automati-
cally reactivated when the trailer's cable
plug is removed.
WARNING!
• Drivers must be careful when backing up
even 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
WARNING!
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 is
unable 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.STARTING AND OPERATING

TOWING A DISABLED
VEHICLE
This section describes procedures for towing
a disabled vehicle using a commercial towing
service. If the transmission and drivetrain are
operable, disabled vehicles may also be
towed as described under “Recreational Tow-
ing” in the “Starting And Operating” section.

FlatbedALL BEST METHOD
Proper towing or lifting equipment is required
to prevent damage to your vehicle. Use only
tow bars and other equipment designed for
this purpose, following equipment manufac-
turer’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towingdevice to main structural members of the
vehicle, not to bumpers or associated brack-
ets. State and local laws regarding vehicles
under tow must be observed.If you must use the accessories (wipers, de-
frosters, etc.) while being towed, the ignition
must be in the ON/RUN position, not the ACC
position.
IN CASE OF EMERGENCY
202

If the vehicle's battery is discharged, refer to
"Manual Park Release" in this section for
instructions on shifting the automatic trans-
mission out of PARK in order to move the
vehicle.
CAUTION!
• Do not use sling type equipment when
towing. Vehicle damage may occur.
• When securing the vehicle to a flatbed
truck, do not attach to front or rear
suspension components. Damage to
your vehicle may result from improper
towing.
• If the vehicle being towed requires steer-
ing, the ignition switch must be in the
ACC or ON/RUN mode, not in the OFF
mode.
Without The Key Fob
Special care must be taken when the vehicle
is towed with the ignition in the OFF mode.
The only approved method of towing without
the key fob is with a flatbed truck. Proper
towing equipment is necessary to prevent
damage to the vehicle.
Four–Wheel Drive Models
The manufacturer recommends towing with
all wheelsOFFthe ground. Acceptable meth-
ods are to tow the vehicle on a flatbed or with
one end of the vehicle raised and the opposite
end on a towing dolly.
If flatbed equipment is not available and the
transfer case is operable, the vehicle may be
towed (in the forward direction, withALL
wheels on the ground),IFthe transfer case is
inNEUTRAL(N) and the transmission is in
PARK. Refer to “Recreational Towing” in
“Starting And Operating” for detailed
instructions.
CAUTION!
• Front or rear wheel lifts must not be used
(if the remaining wheels are on the
ground). Internal damage to the trans-
mission or transfer case will occur if a
front or rear wheel lift is used when
towing.

age. Damage from improper towing is
not covered under the New Vehicle Lim-
ited Warranty.
Tow Eye Usage
Your vehicle is equipped with a tow eye that
can be used to move a disabled vehicle.
When using a tow eye be sure to follow the
“Tow Eye Usage Precautions” and the “Tow-
ing A Disabled Vehicle” instructions in this
section.
The tow eyes are mounted below the front and
rear bumpers.
Tow Eye Usage Precautions
WARNING!
Stand clear of vehicles when pulling with
tow eyes.
• Do not use a chain with a tow eye.
Chains may break, causing serious injury
or death.
203

WARNING!
• Do not use a tow strap with a tow eye.
Tow straps may break or become disen-
gaged, causing serious injury or death.
• Failure to follow proper tow eye usage
may cause components to break result-
ing in serious injury or death.
• The brake and steering power assist sys-
tems will not function while the vehicle
is being towed. You will, therefore, need
to apply more force on the brake pedal
and steering wheel. Do not use flexible
ropes when towing, and avoid jerky
movements. Do not start the engine
while towing the car. Before tightening
the ring, clean the threaded housing
thoroughly. Make sure that the ring is
fully screwed into the housing before
towing the car.
CAUTION!
• The tow eye must only be used for road-
side emergencies. Use with an appropri-
ate device in accordance with highway
code (a rigid bar) to maneuver the ve-
hicle in preparation for transport via a
tow truck.
• The tow eye must not be used to move
the vehicle off the road or where there
are obstacles.
• Do not use the tow eyes for tow truck
hookup or highway towing.
• Do not use the tow eye to free a stuck
vehicle. Refer to the “Freeing A Stuck
Vehicle” section for further information.
• Please refer to the “Towing A Disabled
Vehicle” section for detailed instruc-
tions. Damage to your vehicle may occur
if these guidelines are not followed.NOTE:
• Ensure that the tow eye is properly
mounted.
• Do not use the tow eye to pull the vehicle
onto a flatbed truck.

SCHEDULED SERVICING
Correct servicing is crucial for guaranteeing a
long life for the car under the best conditions.
For this reason, Jeep has planned a series of
checks and services at fixed distance inter-
vals and, where provided, at fixed time inter-
vals, as described in the Scheduled Servicing
plan. To keep the car’s efficiency in tip-top
condition, in the following Scheduled Service
plan pages a few additional checks are listed
that should be carried out more frequently
with respect to the normal coupon redemp-
tion schedule. Scheduled Servicing is offered
by all authorized dealerships according to
fixed time or mileage intervals. If, during
each operation, in addition to the ones
scheduled, the need arises for further re-
placements or repairs, these may be carried
out with the owner's explicit agreement only.
The technicians at your dealership know your
vehicle best, and have access to factory
trained information, genuine Mopar parts,
and specially designed electronic and me-
chanical tools that can help prevent future
costly repairs. If your car is used frequently
for towing, the interval between one sched-uled servicing operation and the next should
be reduced. More frequent maintenance may
be needed for vehicles in severe operating
conditions, such as dusty areas and very
short trip driving.
NOTE:
Scheduled Servicing interventions are set out
by the Manufacturer. Failure to have them
carried out may invalidate the warranty. It is
advised to inform an authorized dealership of
any small operating irregularities without
waiting for the next service.
Scheduled Servicing — Gasoline Engine
The oil change indicator system will remind
you that it is time to take your vehicle in for
engine oil replacement.
On vehicles equipped with instrument cluster
display, “Oil Change Required” will be dis-
played and a single chime will sound, indi-
cating that an oil change is necessary.
On non-instrument cluster display equipped
vehicles, “Change Oil” will flash in the in-
strument cluster odometer and a single
chime will sound, indicating that an oil
change is necessary.The oil change indicator message will illumi-
nate approximately 7,000 miles
(11,200 km) after the most recent oil change
was performed. Have your vehicle serviced as
soon as possible, within 500 miles (800 km)
(except for 2.0L gasoline engine with GPF -
Gasoline Particulate Filter). However, an ear-
lier oil change at 4,500 miles (7,500 km)
may be required if the vehicle is operated
under “Severe Duty Conditions” later in this
section.
NOTE:
• The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicle's oil if it has been
12 months since your last oil change even
if the oil change indicator message is NOT
illuminated.
• Change your engine oil more often if you
drive your vehicle off-road for an extended
period of time.
• Under no circumstances should oil change
intervals exceed 7,500 miles (12,000 km)
or 12 months, whichever comes first (ex-
cept for 2.0L gasoline engine with GPF -
Gasoline Particulate Filter).
