INTRODUCTION
This Owner’s Manual has been prepared with the assis-
tance of service and engineering specialists to acquaint
you with the operation and maintenance of your vehicle.
It is supplemented by a Warranty Information Booklet
and various customer-oriented documents. You are
urged to read these publications carefully. Following the
instructions 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 referencing 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.
ROLLOVER WARNING
Utility vehicles have a significantly higher rollover rate
than other types of vehicles. This vehicle has a higher
ground clearance and a higher center of gravity than
many passenger cars. It is capable of performing better in
a wide variety of off-road applications. Driven in an
unsafe manner, all vehicles can go out of control. Because
of the higher center of gravity, if this vehicle is out of
control it may roll over when some other vehicles may
not.
Do not attempt sharp turns, abrupt maneuvers, or other
unsafe driving actions that can cause loss of vehicle
control. Failure to operate this vehicle safely may result
in an accident, rollover of the vehicle, and severe or fatal
injury. Drive carefully.

NOTE:A key that has not been programmed is also
considered an invalid key, even if it is cut to fit the
ignition switch lock cylinder for that vehicle.
During normal operation, after turning on the ignition
switch, the Vehicle Security Light will turn on for three
seconds for a bulb check. If the light remains on after the
bulb check, it indicates that there is a problem with the
electronics. In addition, if the Vehicle Security Light
begins to flash after the bulb check, it indicates that
someone used an invalid key to try to start the engine.
Either of these conditions will result in the engine being
shut off after two seconds.
If the Vehicle Security Light turns on during normal
vehicle operation (vehicle running for longer than 10 sec-
onds), it indicates that there is a fault in the electronics.
Should this occur, have the vehicle serviced as soon as
possible by an authorized dealer. NOTE:
•The Sentry Key
Immobilizer System is not compat-
ible with some aftermarket remote starting systems.
Use of these systems may result in vehicle starting
problems and loss of security protection.
•Exxon/Mobil Speedpass™, additional Sentry Keys ,
or any other transponder-equipped components on
the same key chain will notcause a key-related
(transponder) fault unless the additional part is physi-
cally held against the ignition key being used when
starting the vehicle. Cell phones, pagers, or other
Radio Frequency (RF) electronics will not cause inter-
ference with this system.
All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.

Replacement Keys
NOTE:Only keys that are programmed to the vehicle
electronics can be used to start and operate the vehicle.
Once a Sentry Key is programmed to a vehicle, it cannot
be programmed to any other vehicle.
CAUTION!
Always remove the Sentry Keys from the vehicle
and lock all doors when leaving the vehicle unat-
tended.
At the time of purchase, the original owner is provided
with a four-digit Personal Identification Number (PIN).
Keep the PIN in a secure location. This number is
required for authorized dealer replacement of keys. Du-
plication of keys may be performed at an authorized
dealer or by following the customer key programming procedure. This procedure consists of programming a
blank key to the vehicle electronics. A blank key is one
that has never been programmed.
NOTE:
When having the Sentry Key Immobilizer
System serviced, bring all vehicle keys with you to an
authorized dealer.
Customer Key Programming
If you have two valid Sentry Keys , you can program
new Sentry Keys to the system by performing the
following procedure:
1. Cut the additional Sentry Key Transponder blank(s)
to match the ignition switch lock cylinder key code.
2. Insert the first valid key into the ignition switch. Turn
the ignition switch to the ON position for at least three
seconds, but no longer than 15 seconds. Then, turn the
ignition switch to the LOCK position and remove the first
key.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

3. Insert the second valid key into the ignition switch.
Turn the ignition switch to the ON position within
15 seconds. After 10 seconds, a chime will sound. In
addition, the Vehicle Security Light will begin to flash.
Turn the ignition switch to the LOCK position and
remove the second key.
4. Insert a blank Sentry Keyinto the ignition switch.
Turn the ignition switch to the ON position within
60 seconds. After 10 seconds, a single chime will sound.
In addition, the Vehicle Security Light will stop flashing.
To indicate that programming is complete, the Vehicle
Security Light will turn on again for three seconds and
then turn off.
The new Sentry Key is programmed.The Remote
Keyless Entry (RKE) transmitter will also be pro-
grammed during this procedure.
Repeat this procedure to program up to eight keys. If you
do not have a programmed Sentry Key, contact your
authorized dealer for details. NOTE:
If a programmed key is lost, see your authorized
dealer to have all remaining keys erased from the sys-
tem’s memory. This will prevent the lost key from
starting your vehicle. The remaining keys must then be
reprogrammed. All vehicle keys must be taken to an
authorized dealer at the time of service to be
reprogrammed.
General Information

WARNING!
•The belt and retractor assembly must be replaced
if the seat belt assembly “automatic locking retrac-
tor” feature or any other seat belt function is not
working properly when checked according to the
procedures in the Service Manual.
•Failure to replace the belt and retractor assembly
could increase the risk of injury in collisions.
Seat Belts and Pregnant Women
We recommend that pregnant women use the seat belts
throughout their pregnancy. Keeping the mother safe is
the best way to keep the baby safe.
Pregnant women should wear the lap part of the belt
across the thighs and as snug across the hips as possible.
Keep the belt low so that it does not come across the
abdomen. That way the strong bones of the hips will take
the force if there is a collision.
Seat Belt Extender
If a seat belt is too short, even when fully extended, and
when the adjustable upper shoulder belt anchorage (if so
equipped) is in its lowest position, your authorized
dealer can provide you with a seat belt extender. This
extender should be used only if the existing belt is not
long enough. When it is not required, remove the ex-
tender, and store it.
WARNING!
Using a seat belt extender when not needed can
increase the risk of injury in a collision. Only use
when the lap belt is not long enough when it is worn
low and snug, and in the recommended seating
positions. Remove and store the extender when not
needed.

will cause the system to turn the airbag on. In this case,
the OCS has classified the occupant of the seat as an
adult. An adult occupant needs to sit in a normal position
(with their feet on or near the floor) in order to be
properly classified. Reclining the seat back too far may
change how an occupant is classified by the OCS.
Drivers and adult passengers should verify that the
“PAD Indicator Light” is not illuminated when an adult
is riding in the front passenger seat. If an adult occu-
pant’s weight is transferred to another part of the vehicle
(like the door or instrument panel), the weight sensors in
the seat may not properly classify the occupant. Objects
lodged under the seat or between the seat and the center
console can prevent the occupant’s weight from being
measured properly and may result in the occupant being
improperly classified. Ensure that the front passenger
seatback does not touch anything placed on the back seatbecause this can also affect occupant classification. Also,
if you fold down the rear seat check to be sure it doesn’t
touch the front passenger seat.
If the front passenger seat is damaged in any way, it
should only be serviced by an authorized dealer. If the
seat is removed (or even if the seat attachment bolts are
loosened or tightened in any way), take the vehicle to an
authorized dealer.
If there is a fault present in the OCS, the “Airbag Warning
Light” (a red light located in the center of the instrument
cluster directly in front of the driver) will be turned on.
This indicates that you should take the vehicle to an
authorized dealer. The “Airbag Warning Light” is turned
on whenever there is a fault that can affect the operation
of the airbag system. If there is a fault present in the OCS,
both the “PAD Indicator Light” and the “Airbag Warning
Light” are illuminated to show that the passenger airbag
is turned off until the fault is cleared. If an object is

WARNING!
Unapproved modifications or service procedures to
the front passenger seat assembly or its related com-
ponents may inadvertently change the airbag deploy-
ment in case of a frontal crash. This could result in
death or serious injury to the front seat passenger if
the vehicle is involved in an accident. A modified
vehicle may not comply with required Federal Motor
Vehicle Safety Standards (FMVSS).
If a Deployment Occurs
The airbag system is designed to deploy when the
Occupant Restraint Controller (ORC) detects a moderate-
to-severe collision, to help restrain the driver and front
passenger, and then to immediately deflate.
NOTE:A collision that is not severe enough to need
airbag protection will not activate the system. This does
not mean something is wrong with the airbag system. If you do have a collision which deploys the airbags, any
or all of the following may occur:
•The nylon airbag material may sometimes cause abra-
sions and/or skin reddening to the driver and front
passenger as the airbags deploy and unfold. The
abrasions are similar to friction rope burns or those
you might get sliding along a carpet or gymnasium
floor. They are not caused by contact with chemicals.
They are not permanent and normally heal quickly.
However, if you haven’t healed significantly within a
few days, or if you have any blistering, see your doctor
immediately.
•As the airbags deflate, you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the non-toxic gas used for
airbag inflation. These airborne particles may irritate
the skin, eyes, nose, or throat. If you have skin or eye
irritation, rinse the area with cool water. For nose or
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 65

throat irritation, move to fresh air. If the irritation
continues, see your doctor. If these particles settle on
your clothing, follow the garment manufacturer’s in-
structions for cleaning.
•It is not advisable to drive your vehicle after the
airbags have deployed. If you are involved in another
collision, the airbags will not be in place to protect you.
WARNING!
Deployed airbags and seat belt pretensioners cannot
protect you in another collision. Have the airbags,
seat belt pretensioner, and seat belt retractor assem-
bly replaced by an authorized dealer as soon as
possible. Also, have the Occupant Classification Sys-
tem serviced as well.
Enhanced Accident Response System
In the event of an impact that causes airbag deployment,
with the vehicle stopped, the vehicle communication
network intact, and the power intact, the Enhanced
Accident Response System performs the following func-
tions:
•Cuts off fuel to the engine.
•Flashes hazard lights.
•Turns on the interior lights, which remain on as long as
the battery has power or until the ignition key is
removed.
•Unlocks the doors automatically.
NOTE: The interior lights can only be deactivated if the
key is removed from the ignition switch or the vehicle is
driven.
