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 a Warranty Information Booklet,
located on the DVD, and various customer-oriented
documents. Please take the time to read these publica-
tions carefully. Following the instructions and recom-
mendations 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 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

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 11

NOTE:
•If you try to remove the Key Fob before you place the
shift lever in PARK, it may become trapped tempo-
rarily 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.
•For vehicles equipped with the Electronic Vehicle
Information Center (EVIC), the power window
switches, radio, power sunroof (if equipped), and
power outlets will remain active for up to 10 minutes
after the ignition switch is turned to the LOCK posi-
tion. Opening either front door will cancel this feature.
The time for this feature is programmable. Refer to
“Electronic Vehicle Information Center (EVIC) — IfEquipped/Personal Settings (Customer-
Programmable Features)” in “Understanding Your In-
strument Panel” for further information.
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. Do not leave the Key Fob 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 Key Fob from the ignition and lock all doors
when leaving the vehicle unattended.
14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.
SENTRY KEY
The Sentry Key Immobilizer 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 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
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 position, 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.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 15

1. A weak battery in the RKE transmitter. The expected
life of the battery is a minimum of three years.
2. Closeness to a radio transmitter such as a radio station
tower, airport transmitter, and some mobile or CB radios.
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 328 ft (100 m).
NOTE: The vehicle must be equipped with an auto-
matic transmission to be equipped with Remote Start.
How to Use Remote Start
All of the following conditions must be met before the
engine will remote start:
•Shift lever in PARK
•Doors closed
•Hood closed
•Liftgate closed
•Hazard switch off
•Brake switch inactive (brake pedal not pressed)
•Ignition key removed from ignition switch
•Battery at an acceptable charge level
•RKE PANIC button not pressed
24 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Mon-
oxide (CO) which is odorless and colorless. Car-
bon Monoxide is poisonous and can cause serious
injury or death when inhaled.
•Keep Remote Keyless Entry (RKE) transmitters
away from children. Operation of the Remote Start
System, windows, door locks or other controls
could cause serious injury or death.
To Enter Remote Start Mode
Press and release the REMOTE START button
on the RKE transmitter twice, within five sec-
onds. The parking lights will flash and the horn
will chirp twice (if programmed). Then, the
engine will start and the vehicle will remain in the
Remote Start mode for a 15 minute cycle. NOTE:
•If an engine fault is present the vehicle will start and
then shut down 10 seconds later.
•The park lamps will turn on and remain on during
Remote Start mode.
•For security, power window and power sunroof op-
eration (if equipped) are disabled when the vehicle is
in the Remote Start mode.
•The engine can be started two consecutive times (two
15 minute cycles) with the RKE transmitter. However,
the ignition switch must be cycled to the ON position
before you can repeat the start sequence for a third
cycle.
To Exit Remote Start Mode Without Driving the
Vehicle
Press and release the REMOTE START button one time or
allow the engine to run for the entire 15 minute cycle.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 25

1. Turn the ignition switch to the OFF position, and
buckle the driver’s seat belt.
2. Turn the ignition key to the ACC/ON position (do not
start the engine), and wait for the Seat Belt Reminder
Light to turn off.
3. Within 60 seconds of starting the vehicle, unbuckle
and then re-buckle the driver’s seat belt at least three
times within 10 seconds, ending with the seat belt
buckled.
4. Turn the ignition key to the OFF position. A single
chime will sound to signify that you have successfully
completed the programming.
BeltAlertcan be reactivated by repeating this procedure.
NOTE: Although BeltAlert has been deactivated, the
Seat Belt Reminder Light will continue to illuminate
while the driver’s seat belt remains unfastened.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
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.
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Front and Side Impact Sensors
In front and side impacts, impact sensors aid the ORC in
determining appropriate response to impact events. Ad-
ditional sensors in the ORC determine the level of airbag
deployment and provide verification.
Enhanced Accident Response System
In the event of an impact causing airbag deployment, if
the communication network remains intact, and the
power remains intact, depending on the nature of the
event the ORC will determine whether to have the
Enhanced Accident Response System perform the follow-
ing functions:
•Cut off fuel to the engine.
•Flash hazard lights as long as the battery has power or
until the ignition key is turned off.
•Turn on the interior lights, which remain on as long as the
battery has power or until the ignition key is removed.
•Unlock the doors automatically.
If a Deployment Occurs
The front airbags are designed to deflate immediately
after deployment.
NOTE:Front and/or side airbags will not deploy in all
collisions. 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.
