INTRODUCTION
Congratulations on selecting your new Chrysler Group

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

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 MOPARparts, 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

at the top of the Key Fob sideways with your thumb and
then pull the key out with your other hand.
NOTE:You can insert the double-sided emergency key
into the lock cylinders with either side up.Removing Key Fob From Ignition
Place the shift lever in PARK. Turn the Key Fob to the
OFF position and then remove the Key Fob.
With the Keyless Enter-N-Go feature, the EVIC will
display the ignition switch position “OFF/ACC/RUN”.
Refer to “Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for further
information.
NOTE:
•If you try to remove the Key Fob before you place the
shift lever in PARK, it may become trapped temporar-
ily in the ignition switch. If this occurs, rotate the key
to the right slightly, then remove the Key Fob as
described. If a malfunction occurs, the system will trap
the key in the ignition switch to warn you that this
safety feature is inoperable. The engine can be started
and stopped, but the Key Fob cannot be removed until
you obtain service.
Emergency Key Removal
14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING! (Continued)
•Do not leave the key fob in or near the vehicle, and
do not leave Keyless Enter-N-Go in the ACC or
ON/RUN mode. A child could operate power win-
dows, other controls, or move the vehicle.
•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 car is an invitation to thieves. Always
remove Key Fob from the ignition and lock all doors
when leaving the vehicle unattended.
Key-In-Ignition Reminder
Opening the driver’s door when the Key Fob is in the
ignition and the ignition switch position is OFF or ACC,
sounds a signal to remind you to remove the Key Fob.NOTE:The Key-In-Ignition reminder only sounds
when the Key Fob is placed in the OFF or ACC ignition
position.
With the Keyless Enter-N-Go feature, opening the driv-
er’s door when the vehicle’s ignition switch is placed in
ACC or ON/RUN (engine stopped) will cause the re-
minder chime to sound. Refer to “Starting Procedures” in
“Starting And Operating” for further information.
SENTRY KEY
The Sentry KeyImmobilizer 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 the factory-mated Key Fob with Remote
Keyless Entry (RKE) transmitter and Wireless Ignition
Node (WIN) to prevent unauthorized vehicle operation.
Therefore, only Key Fobs that are programmed to the
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

vehicle can be used to start and operate the vehicle. The
system will shut the engine off in two seconds if an
invalid Key Fob is used to start the engine.
After turning the ignition switch to the ON/RUN posi-
tion, 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 light begins to flash after
the bulb check, it indicates that someone used an invalid
Key Fob 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 KeyImmobilizer 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 Key Fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE:Only Key Fobs that are programmed to the
vehicle electronics can be used to start and operate the
vehicle. Once a Key Fob is programmed to a vehicle, it
cannot be programmed to any other vehicle.

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 received,
including interference that may cause undesired
operation.
NOTE:Changes or modifications not expressly ap-
proved by the party responsible for compliance could

REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the Remote Keyless Entry
(RKE) transmitter to start the engine conve-
niently from outside the vehicle while still
maintaining security. The system has a range of
approximately 300 ft (91 m).
NOTE:
•The vehicle must be equipped with an automatic
