FOUR-WHEEL DRIVE OPERATION — IF EQUIPPED
This feature provides full time, on-demand, four–wheel
drive (4WD).
Where one or more wheels have wheel spin or if addi-
tional traction is needed in sand, deep snow, or loosetraction surfaces, activate the “4WD LOCK” switch by
pulling up once and releasing. This locks the center
coupling allowing more torque to be sent to the rear
wheels. The “4WD Indicator Light” will come on in the
cluster. This can be done on the fly, at any vehicle speed.
To deactivate, simply pull on the switch one more time.
The “4WD Indicator Light” will then go out.
NOTE:
Refer to “Electronic Brake Control System/
Electronic Stability Control (ESC)” in “Starting and Op-
erating” for further information.
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 applications. Specific design
characteristics give them a higher center of gravity than
ordinary cars.

CAUTION!
Muddy waters can reduce the cooling system effec-
tiveness by depositing debris onto the radiator.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you
can get any problems taken care of right away and have
your vehicle ready when you need it.
•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required. •
Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
• After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.
354 STARTING AND OPERATING

Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system functions similar to
a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESC are in
either the “Partial Off” or “Full Off” modes. Refer to
“Electronic Stability Control (ESC)” in this section of this
manual.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must applycontinuousbrak-
ing pressure during the stopping sequence (do not
“pump” the brakes). Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.

WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.
Torque Specifications
Lug Nut/Bolt Torque **Lug Nut/Bolt SizeLug Nut/
Bolt
Socket Size
100 Ft-Lbs (135 N·m) M12 x 1.25 19 mm
**Use only Chrysler recommended lug nuts/bolts and
clean or remove any dirt or oil before tightening. Inspect the wheel mounting surface prior to mounting
the tire and remove any corrosion or loose particles.

WHAT TO DO IN EMERGENCIES 437

Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice.
After 25 miles (40 km) check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated
against the wheel.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 personal injury.
JACKING AND TIRE CHANGING
WARNING!
•Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.

438 WHAT TO DO IN EMERGENCIES

CAUTION!
Be sure to mount the spare tire with the valve stem
facing outward. The vehicle could be damaged if the
spare tire is mounted incorrectly.
WARNING!
To avoid possible personal injury, handle the wheel
covers with care to avoid contact with any sharp
edges.
NOTE: The wheel cover is held on the wheel by the
wheel nuts. When reinstalling the original wheel, prop-
erly align the wheel cover to the valve stem, place the
wheel cover onto the wheel, then install the wheel nuts.
6. Lower the vehicle by turning the jack screw to the left.
7. 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. Refer to “Torque
Specifications” in this section for the correct lug nut
torque. If you doubt that you have tightened the nuts
correctly, have them checked with a torque wrench by
your authorized dealer or service station.
8. Remove the wheel blocks and lower the jack until it is free. Release the parking brake. Reassemble the lug
wrench to the jack assembly and stow it in the spare
tire area. Secure the assembly using the means pro-
vided.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
446 WHAT TO DO IN EMERGENCIES

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 personal injury.
4. Lower the vehicle to the ground by turning the jack handle counterclockwise.
5. Finish tightening the lug nuts. Push down on the wrench while at the end of the handle for increased
leverage. Refer to “Torque Specifications” in this sec-
tion for correct lug nut torque.
6. 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.
Vehicles Without Wheel Covers
1. Mount the road tire on the axle.
2.
Install the remaining lug nuts with the cone 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 fully tighten the lug nuts until the vehicle has
been lowered. Failure to follow this warning may
result in personal 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. Refer to “Torque Specifications” in this sec-
tion for correct lug nut torque.

5. After 25 miles (40 km) check the lug nut torque with atorque wrench to ensure that all lug nuts are properly
seated against the wheel.
TIREFIT KIT — IF EQUIPPED
Small punctures up to ¼” (6 mm) in the tire tread can be
sealed with TIREFIT. Foreign objects (e.g., screws or
nails) should not be removed from the tire. TIREFIT can
be used in outside temperatures down to approximately
-4°F (-20°C).
This kit will provide a temporary tire seal, allowing you
to drive your vehicle up to 100 miles (160 km) with a
maximum speed of 55 mph (90 km/h).
TIREFIT Storage
The TIREFIT kit is located under the load floor in the
cargo area.
