alcohol levels far below the legal minimum. If you are drink-
ing, don’t drive. Ride with a designated non-drinking driver,
call a cab, a friend, or use public transportation.
WARNING!
Driving after drinking can lead to an accident. Your
perceptions are less sharp, your reflexes are slower,
and your judgment is impaired when you have been
drinking. Never drink and then drive.
This manual illustrates and describes the operation of fea-
tures and equipment that are either standard or optional on

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 is a specialized utility vehicle. It can go places and
perform tasks that conventional passenger cars are not
intended. It handles and maneuvers differently from
many passenger cars both on-road and off-road, so take
time to become familiar with your vehicle.
The two-wheel drive version of this vehicle was designed
for on-road use only. It is not intended for off-road
driving or use in other severe conditions suited for a
four-wheel drive vehicle.
Before you start to drive this vehicle, read the Owner’s
Manual. Be sure you are familiar with all vehicle controls,
particularly those used for braking, steering, transmis-
sion, and transfer case shifting. Learn how your vehicle
handles on different road surfaces. Your driving skills
will improve with experience. When driving off-road or
working the vehicle, don’t overload the vehicle or expect
the vehicle to overcome the natural laws of physics.
Always observe federal, state, provincial and local laws
wherever you drive.
As with other vehicles of this type, failure to operate this
vehicle correctly may result in loss of control or a
collision. Refer to “On-Road/Off-Road Driving Tips” in
“Starting And Operating” for further information.
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.
4 INTRODUCTION

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威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 and the narrower track, 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.
Rollover Warning Label
1
INTRODUCTION 5

Failure to use the driver and passenger seat belts pro-
vided is a major cause of severe or fatal injury. In a
rollover crash, an unbelted person is significantly more
likely to die than a person wearing a seat belt. Always
buckle up.
HOW TO USE THIS MANUAL

A WORD ABOUT YOUR KEYS
The keys for your new vehicle are enclosed in a plastic
bag with the key code number on it. If you received your
keys without the bag, ask your authorized dealer to give
you the number. The key code can also be obtained by
your authorized dealer from your vehicle invoice.
Ignition Key Removal

automatic transmission).
2. Turn the ignition switch to the ACC (ACCESSORY)
position.
3. Push the ignition key inward.
4. Turn the ignition key to the LOCK position, and
remove the key.
Ignition Switch Positions

14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
• Before exiting a vehicle, always apply the parking
brake, shift the transmission into PARK, and re-
move the key fob from the ignition. When leaving
the vehicle, always lock your vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
• Allowing children to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured. Chil-
dren should be warned not to touch the parking
brake, brake pedal or the shift lever.
• Do not leave the key fob in or near the vehicle, and
do not leave the ignition in the ACC or ON/RUN
position. A child could operate power windows,
other controls, or move the vehicle.
(Continued)
WARNING! (Continued)
• Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
CAUTION!
An unlocked vehicle is an invitation to thieves.
Always remove the key from the ignition, and lock
all doors when leaving the vehicle unattended.
Key-In-Ignition Reminder
Opening the driver’s door when the key is in the ignition
sounds a signal to remind you to remove the key.
NOTE: The Key-In-Ignition reminder only sounds
when the ignition key is placed in the LOCK or ACC
position.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 15

SENTRY KEY姞
The Sentry Key威Immobilizer System prevents unauthor-
ized vehicle operation by disabling the engine. The
system does not need to be armed or activated. Operation
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威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.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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威is programmed to a vehicle, it cannot
be programmed to any other vehicle.
CAUTION!
Always remove the Sentry Keys威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威Immobilizer
System serviced, bring all vehicle keys with you to an
authorized dealer.
Customer Key Programming
If you have two valid Sentry Keys威, you can program
new Sentry Keys威to the system by performing the
following procedure:
1. Cut the additional Sentry Key威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.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 17

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 Key威into 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威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威, 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.
General Information
The Sentry Key威system complies with FCC rules Part 15
and with RSS-210 of Industry Canada. Operation is
subject to the following conditions:
• This device may not cause harmful interference.
• This device must accept any interference that may be
received, including interference that may cause unde-
sired operation.
