Recreational Towing-Two Wheel Drive
Models
DO NOT flat tow this vehicle. Damage to the
drivetrain will result.
Recreational towing (for two-wheel drive
models) is allowed ONLY if the rear wheels
are OFF the ground. This may be accom-
plished using a tow dolly or vehicle trailer. If
using a tow dolly, follow this procedure:
1. Properly secure the dolly to the tow ve-hicle, following the dolly manufacturer's
instructions.
NOTE:
If vehicle is equipped with Quadra-Lift air
suspension, ensure the vehicle is set to
Normal Ride Height.
2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Shift the transmission into PARK.
4. Turn the ignition OFF.
5. Properly secure the rear wheels to the dolly, following the dolly manufacturer’s
instructions. 6. Install a suitable clamping device, de-
signed for towing, to secure the front
wheels in the straight position.
CAUTION!
Towing with the rear wheels on the ground
will cause severe transmission damage.
Damage from improper towing is not cov-
ered under the New Vehicle Limited War-
ranty.
Recreational Towing — Quadra-Trac I
(Single-Speed Transfer Case) Four-Wheel
Drive Models
Recreational towing is not allowed. These
models do not have a NEUTRAL (N) position
in the transfer case.
NOTE:
This vehicle may be towed on a flatbed or
vehicle trailer provided all four wheels are OFF
the ground.
CAUTION!
Towing this vehicle in violation of the
above requirements can cause severe
transmission and/or transfer case damage.
Damage from improper towing is not cov-
ered under the New Vehicle Limited War-
ranty.
Recreational Towing — Quadra–Trac

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.

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.

ings to help prevent personal injury or
damage to your vehicle:
• Always park on a firm, level surface asfar from the edge of the roadway as
possible before raising the vehicle.
• Turn on the Hazard Warning flasher.
• Chock the wheel diagonally opposite the
wheel to be raised.
• Set the parking brake firmly and set an
automatic transmission in PARK.
• Never start or run the engine with the
vehicle on a jack.
• Do not let anyone sit in the vehicle when
it is on a jack.
• Do not get under the vehicle when it is
on a jack. If you need to get under a
raised vehicle, take it to a service center
where it can be raised on a lift.
• Only use the jack in the positions indi-
cated and for lifting this vehicle during a
tire change.
WARNING!
• If working on or near a roadway, beextremely careful of motor traffic.
• To assure that spare tires, flat or in-
flated, are securely stowed, spares must
be stowed with the valve stem facing the
ground.
CAUTION!
Do not attempt to raise the vehicle by
jacking on locations other than those indi-
cated in the Jacking Instructions for this

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).
11. Lower the jack to the fully closed posi- tion and return it and the tools to the
proper positions in the foam tray.
12. Remove the small center cap and se- curely store the road wheel in the cargo
area. 13. Have the aluminum road wheel and tire
repaired as soon as possible, properly
secure the spare tire with the special
wing nut torqued to 3.7 ft-lbs (5 N·m),
reinstall the jack and tool kit foam tray,
and latch the rear load floor cover.
NOTE:
Do not drive with the spare tire installed for
more than 50 miles (80 km) at a max speed
of 50 mph (80 km/h).

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.
221

FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand
or snow, it can often be moved using a rock-
ing motion. Turn the steering wheel right and
left to clear the area around the front wheels.
Push and hold the lock button on the gear
selector. Then shift back and forth between
DRIVE and REVERSE while gently pressing
the accelerator.
NOTE:
Shifts between DRIVE and REVERSE can
only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission
remains in NEUTRAL for more than two sec-
onds, you must press the brake pedal to
engage DRIVE or REVERSE.
Use the least amount of accelerator pedal
pressure that will maintain the rocking mo-
tion without spinning the wheels or racing the
engine.NOTE:
Push the "ESC Off" switch (if necessary), to
place the Electronic Stability Control (ESC)
system in "Partial Off" mode, before rocking
the vehicle. Refer to “Electronic Brake Con-
trol” in “Safety” in the Owners Manual at
www.jeep.com/en/owners/manuals/ for fur-
ther information. Once the vehicle has been
freed, push the "ESC Off" switch again to
restore "ESC On" mode.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause damage, or even failure,
of the axle and tires. A tire could explode
and injure someone. Do not spin your
vehicle's wheels faster than 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping when you
are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
CAUTION!
• Racing the engine or spinning the
wheels may lead to transmission over-
heating and failure. Allow the engine to
idle with the transmission in NEUTRAL
for at least one minute after every five
rocking-motion cycles. This will mini-
mize overheating and reduce the risk of
transmission failure during prolonged
efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shift-
ing between DRIVE and REVERSE, do
not spin the wheels faster than 15 mph
(24 km/h), or drivetrain damage may
result.
• Revving the engine or spinning the
wheels too fast may lead to transmission
overheating and failure. It can also dam-
age the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).
