INTRODUCTION
Congratulations on selecting your new Chrysler Group
LLC vehicle. Be assured that it represents precision
workmanship, distinctive styling, and high quality - all
essentials that are traditional to our vehicles.
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 Warranty Information, and various
customer-oriented documents. Please take the time 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 reviewing the owner information, it
should be stored in the vehicle for convenient referenc-
ing and remain with the vehicle when sold.When it comes to service, remember that your authorized
dealer knows your vehicle best, has factory-trained tech-
nicians and genuine MOPAR
parts, and cares about
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 a collision, rollover of the vehicle, and severe or fatal
injury. Drive carefully.

is automatic, regardless of whether the vehicle is locked
or unlocked.
The system uses ignition keys that have an embedded
electronic chip (transponder) to prevent unauthorized
vehicle operation. Therefore, only keys that are pro-
grammed to the vehicle can be used to start and operate
the vehicle. The system will shut the engine off in two
seconds if someone uses an invalid key to try to start the
engine.
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.
CAUTION!
The Sentry Key
Immobilizer system is not compat-
ible with some after-market remote starting systems.
Use of these systems may result in vehicle starting
problems and loss of security protection.
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/RUN 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.

3. Insert the second valid key into the ignition switch.
Turn the ignition switch to the ON/RUN 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/RUN 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 repro-
grammed. All vehicle keys must be taken to an authorized
dealer at the time of service to be reprogrammed.

anytime a child safety seat is installed in a seating
position that has a belt with this feature. Children
12 years old and under should always be properly
restrained in the rear seat.
How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulder belt.
2. Grasp the shoulder portion and pull downward until
the entire belt is extracted.
3. Allow the belt to retract. As the belt retracts, you will
hear a clicking sound. This indicates the safety belt is
now in the Automatic Locking Mode.
How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt and allow it
to retract completely to disengage the Automatic Locking
Mode and activate the vehicle sensitive (emergency)
locking mode.
WARNING!
•The belt and retractor assembly must be replaced
if the seat belt assembly Automatic Locking Re-
tractor (ALR) feature or any other seat belt func-
tion is not working properly when checked ac-
cording to the procedures in the Service Manual.
•Failure to replace the belt and retractor assembly
could increase the risk of injury in collisions.
Energy Management Feature
This vehicle has a safety belt system with an energy
management feature in the front seating positions to help
further reduce the risk of injury in the event of a head-on
collision.
This safety belt system has a retractor assembly that is
designed to release webbing in a controlled manner. This
feature is designed to help reduce the belt force acting on
the occupant’s chest.

WARNING!
•The belt and retractor assembly must be replaced
if the seat belt assembly “Automatic Locking Re-
tractor (ALR)” feature or any other seat belt func-
tion is not working properly when checked ac-
cording to the procedures in the Service Manual.
•Failure to replace the belt and retractor assembly
could increase the risk of injury in accidents.
Seat Belt Pretensioner
The belt for driver seating position is equipped with a
retractor pretensioning device, the belt for passenger
seating position is equipped with both retractor and
buckle pretensioning devices. These devices are designed
to remove any slack from the seat belt systems in the
event of a collision. These devices may improve the
performance of the seat belt by assuring that the belt istight around the occupant early in a collision. Pretension-
ers work for all size occupants, including those in child
restraints.
NOTE:
These devices are not a substitute for proper seat
belt placement by the occupant. The seat belt must still be
worn snugly and positioned properly.
The pretensioners are triggered by the Occupant Re-
straint Controller (ORC). Like the air bags, the preten-
sioners are single use items. A deployed pretensioner or
a deployed air bag must be replaced immediately.Supplemental Active Head Restraints (AHR)
These head restraints are passive, deployable compo-
nents, and vehicles with this equipment cannot be readily
identified by any markings, only through visual inspec-
tion of the head restraint. The head restraint will be split
in two halves, with the front half being soft foam and
trim, the back half being decorative plastic.

WARNING!
Ignoring the Air Bag Warning Light in your instru-
ment panel could mean you won’t have the air bags
to protect you in a collision. If the light does not come
on as a bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if it comes
on as you drive, have an authorized dealer service the
air bag system immediately.
Occupant Classification System (OCS)
The OCS is part of a Federally regulated safety system
required for this vehicle. It is designed to turn off the
passenger Advanced Front Air Bag for an empty seat and
for occupants classified in a category other than an adult.
This could be a child, teenager, or even an adult.
NOTE:Children 12 years or younger should always
ride buckled up in a rear seat in an appropriate child
restraint.
•Occupant Classification Module (OCM)
The OCM is located beneath the front passenger seat. The
OCM classifies the occupant into categories based on the
measurements made by the seat weight sensors. The
OCM communicates with the ORC. The ORC uses the
occupant category to determine whether the passenger
Advanced Front Air Bag should be turned off. It also
determines the rate of air bag inflation during a collision.
•Weight Sensors
Your vehicle has four Weight Sensors located between the
seat and the floor pan. The weight sensors measure
applied weight and transfers that information to the
OCM.
•Passenger Air Bag Disable (PAD) Indicator Light
The PAD Indicator Light (an amber light located in the
center of the instrument panel) tells the driver and front
passenger when the passenger Advanced Front Air Bag is
turned off. The PAD Indicator light illuminates the words
