Operating this vehicle at excessive speeds or while
intoxicated may result in loss of control, collision with
other vehicles or objects, going off the road, or overturn-
ing, any of which may lead to serious injury or death.
Also,failure to use standard seat beltssubjects the
driver and passengers to a greater risk of being thrown
out of an open-body vehicle than out of a closed vehicle
in an accident which can result in injury or death.
This manual has been prepared with the assistance of
service and engineering specialists to acquaint you with
the operation and maintenance of your new vehicle. It is
supplemented by a Warranty Information Booklet and
various customer oriented documents. You are urged to
read these publications carefully. Following the instruc-
tions and recommendations in this manual will help
assure safe and enjoyable operation of your vehicle.NOTE: After you read the manual, it should be stored
in the vehicle for convenient reference and remain with
the vehicle when sold so that the new owner will be
aware of all safety warnings.
When it comes to service, remember that your authorized
dealer knows your vehicle best, has the factory-trained
technicians and genuine Moparparts, and is interested
in your satisfaction.

Maintaining Your Airbag System
WARNING!
•Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured because the airbags are not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or
the upper right side of the instrument panel. Do
not modify the front bumper, vehicle body struc-
ture, or frame.
•You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolster.
•It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has airbags.
Airbag Warning Light
You will want to have the airbags ready to inflate for your
protection in an collision. While the airbag system is
designed to be maintenance free, if any of the following
occurs, have an authorized dealer service the system
immediately.
•The “Airbag Warning Light” does not come on or
flickers during the 6 to 8 seconds when the ignition
switch is first turned on.
•The “Airbag Warning Light” remains on or flickers
after the 6 to 8 second interval.
•The “Airbag Warning Light” flickers or comes on and
remains on while driving.

Satellite Antenna
To ensure optimum reception, do not place items on the
roof around the rooftop antenna location. Metal objects
placed within the line of sight of the antenna will cause
decreased performance. Larger luggage items should be
placed as far forward as possible. Do not place items
directly on or above the antenna.
Reception Quality
Satellite reception may be interrupted due to one of the
following reasons.
•The vehicle is parked in an underground parking
structure or under a physical obstacle.
•Dense tree coverage may interrupt reception in the
form of short audio mutes.
•Driving under wide bridges or along tall buildings can
cause intermittent reception.
•Placing objects over or too close to the antenna can
cause signal blockage.
CASSETTE TAPE AND PLAYER MAINTENANCE
To keep the cassette tapes and player in good condition,
take the following precautions:
1. Do not use cassette tapes longer than C-90; otherwise,
sound quality and tape durability will be greatly dimin-
ished.
2. Keep the cassette tape in its case to protect from
slackness and dust when it is not in use.
3. Keep the cassette tape away from direct sunlight, heat
and magnetic fields such as the radio speakers.
4. Before inserting a tape, make sure that the label is
adhering flat to the cassette.

5. A loose tape should be corrected before use. To rewind
a loose tape, insert the eraser end of a pencil into the tape
drive gear and twist the pencil in the required directions.
Maintain your cassette tape player. The head and capstan
shaft in the cassette player can pick up dirt or tape
deposits each time a cassette is played. The result of
deposits on the capstan shaft may cause the tape to wrap
around and become lodged in the tape transport. The
other adverse condition is low or “muddy” sound from
one or both channels, as if the treble tone control were
turned all the way down. To prevent this, you should
periodically clean the head with a commercially available
WET cleaning cassette.
As preventive maintenance, clean the head about every
30 hours of use. If you wait until the head becomes very
dirty (noticeably poor sound), it may not be possible to
remove all deposits with a simple WET cleaning cassette.CD/DVD DISC MAINTENANCE
To keep the CD/DVD discs in good condition, take the
following precautions:
1. Handle the disc by its edge; avoid touching the
surface.
2. If the disc is stained, clean the surface with a soft cloth,
wiping from center to edge.
3. Do not apply paper, paper CD labels, or tape to the
disc; avoid scratching the disc.
4. Do not use solvents such as benzine, thinner, cleaners,
or antistatic sprays.
5. Store the disc in its case after playing.
6. Do not expose the disc to direct sunlight.
7. Do not store the disc where temperatures may become
too high.

NOTE:Your vehicle has automatically adjusting rear
brakes and we do not recommend any adjustment other
than the maintenance performed by your authorized
dealer.
Before leaving the vehicle parked on a hill, you must
make sure the parking brake is fully applied and place
the gear selector in the P (Park) position (automatic
transmission) or first gear (manual transmission). Make
certain the transfer case is in gear. Failure to do so may
cause the vehicle to roll and cause damage or injury.WARNING!
•Always fully apply the parking brake when leav-
ing your vehicle, or vehicle may roll and cause
damage or injury. Also be certain to leave a
automatic transmission in P (Park), or a manual
transmission in 1st gear. Make certain the transfer
case is in gear. Failure to do so may cause the
vehicle to roll and cause damage or injury.
•If the parking brake is released, and the BRAKE
warning light glows while the ignition switch is
ON or the engine is running, there may be a brake
system problem. Brake pedal travel, effort and
stopping distances may increase, and you should
obtain corrective service immediately.
When parking on a hill, it is important to set the parking
brake before placing the gear selector in P (Park), other-
wise the load on the transmission locking mechanism
may make it difficult to move the selector out of P (Park).

Standing Water
Avoid driving in standing water deeper than 20 inches,
and reduce speed appropriately to minimize wave ef-
fects. Maximum speed in 20 inches of water is less than 5
mph (8 km/h).
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine oil, transmission oil, axle,
transfer case) to assure the fluids have not been contami-
nated. Contaminated fluid (milky, foamy in appearance)
should be flushed/changed as soon as possible to pre-
vent component damage.
Driving In Snow, Mud and Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4L (Low) if necessary.
Refer to “Four-Wheel Drive Operation” in this section.Do not shift to a lower gear than necessary to maintain
headway. Over-revving the engine can spin the wheels
and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads, be-
cause engine braking may cause skidding and loss of
control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill,shift the transmission to a
lower gear and shift the transfer case to 4L (Low). Use
first gear and 4L (Low) for very steep hills.
If you stall or begin to lose headwaywhile climbing a
steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine and
shift to R (Reverse). Back slowly down the hill allowing
the compression braking of the engine to help regulate
