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 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.
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:If you try to remove the key before you place the
shift lever in PARK, the key may become trapped tem-
porarily in the ignition cylinder. If this occurs, rotate the
key to the right slightly, then remove the key as de-
scribed. If a malfunction occurs, the system will trap the
key in the ignition cylinder to warn you that this safety
feature is inoperable. The engine can be started and
stopped but the key cannot be removed until you obtain
service.
WARNING!
Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be seri-
ously or fatally injured. Don’t leave the keys in the
ignition. A child could operate power windows,
other controls, or move the vehicle.
CAUTION!
An unlocked car is an invitation to thieves. Always
remove the key from the ignition and lock all the
doors when leaving the vehicle unattended.
Locking Doors With The Key
You can insert the key with either side up. To lock the
door, turn the key rearward. To unlock the door, turn the
key forward. Refer to “Body Lubrication” under “Main-
tenance Procedures” in Section 7.
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:With the driver’s door open and the key in the
ignition, both the power door locks and Remote Keyless
Entry (RKE) will not function.
14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

SENTRY KEY
The Sentry KeyImmobilizer System prevents unautho-
rized 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 threeseconds 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 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
seconds), it indicates that there is a fault in the electron-
ics. Should this occur, have the vehicle serviced as soon
as possible.
NOTE:
•The Sentry KeyImmobilizer 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.

To Disarm The Security Alarm System
1. Press UNLOCK on the RKE transmitter.

Security Alarm System Manual Override
The Security Alarm System will not arm if you lock the
doors using the manual door lock plunger.
REMOTE KEYLESS ENTRY (RKE)— IF EQUIPPED
This system allows you to lock or unlock the doors and
liftgate or activate the panic alarm from distances up to
66 ft (20 m) using a hand-held Remote Keyless Entry
(RKE) transmitter. The RKE transmitter does not need to
be pointed at the vehicle to activate the system.NOTE:The line of transmission must not be blocked
with metal objects.

be programmed must be done so within 60 seconds of
when the chime is heard.

and release both the LOCK and UNLOCK buttons simul-
taneously.
