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 vehiclehandles 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.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 13

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 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.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

1. With the RKE transmitter buttons facing down, use a
flat blade screwdriver to pry the two halves of the RKE
transmitter apart. Useextreme carenot to damage the
seal or internal components. 2. Remove and replace the battery. Avoid touching the
new battery with your fingers. Skin oils may cause
battery deterioration. If you touch a battery, clean it with
rubbing alcohol.
3. To reassemble the RKE transmitter case, snap the two
halves together.
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
transmission to be equipped with Remote Start.
•Obstructions between the vehicle and RKE transmitter
may reduce this range.

26 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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
•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
•System not disabled from previous remote start event
•Vehicle theft alarm not active
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.
Remote Start Abort Message On Electronic Vehicle
Information Center (EVIC) — If Equipped
The following messages will display in the EVIC if the

The EVIC message stays active until the ignition is turned
to the ON/RUN position.
To Enter Remote Start
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:
•The park lamps will turn on and remain on during
Remote Start mode.
•For security, power window operation is 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/RUN
position before you can repeat the start sequence for a
third cycle.
Remote start will also cancel if any of the following occur:
•The engine stalls or RPM exceeds 2500
•Any engine warning lamps come on
•The hood is opened
•The hazard switch is pressed
•The transmission is moved out of PARK
•The brake pedal is pressed

will disable the one time press of the REMOTE START
button for two seconds after receiving a valid Remote
Start request.
To Exit Remote Start Mode And Drive The Vehicle
Before the end of the 15-minute cycle, press and release
the UNLOCK button on the RKE transmitter to unlock
the doors and disarm the Vehicle Security Alarm (if equipped). Then, insert the key into the ignition switch
and turn the switch to the ON/RUN position.
NOTE:
The ignition switch must be in the ON/RUN
position in order to drive the vehicle.
DOORS
CAUTION!
Careless handling and storage of the removable door
panels may damage the seals, causing water to leak
into the vehicle’s interior.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 29

The ORC determines if a side collision requires the side
air bags to inflate, based on several factors, including the
severity and type of collision.
Based on several factors, including the severity and type
of collision, the side air bag inflator on the crash side of
the vehicle is triggered, releasing a quantity of non-toxic
gas. The inflating SAB exits through the seat seam into
the space between the occupant and the door. The SAB
fully inflate in about 10 milliseconds. The side air bag
moves at a very high speed and with such a high force
that it could injure you if you are not seated properly, or
if items are positioned in the area where the side air bag
inflates. This especially applies to children.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and the front passenger, and position front occu-
pants for the best interaction with the Advanced Front
Air Bag.
Front And Side Impact Sensors
In front and side impacts, front and side impact sensors
can aid the ORC in determining the appropriate response
to certain impact events.
Enhanced Accident Response System
In the event of an impact causing air bag 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.
66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. The air bags may
not be ready to inflate for your protection. Promptly
check the fuse block for blown fuses. Refer to the label
located on the inside of the fuse block cover for the
proper air bag fuses. See your authorized dealer if the
fuse is good.
Event Data Recorder (EDR)
This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record, in
certain crash or near crash-like situations, such as an air
bag deployment or hitting a road obstacle, data that will
assist in understanding how a vehicle’s systems per-
formed. The EDR is designed to record data related to
vehicle dynamics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this vehicle
is designed to record such data as:
•How various systems in your vehicle were operating;
•Whether or not the driver and passenger safety belts
were buckled/fastened;
•How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
•How fast the vehicle was traveling.
These data can help provide a better understanding of
the circumstances in which crashes and injuries occur.
NOTE: EDR data are recorded by your vehicle only if a
non-trivial crash situation occurs; no data are recorded by
the EDR under normal driving conditions and no per-
sonal data (e.g., name, gender, age, and crash location)
are recorded. However, other parties, such as law en-
forcement, could combine the EDR data with the type of
personally identifying data routinely acquired during a
crash investigation.
70 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•If the belt still can’t be tightened, or if pulling and
pushing on the restraint loosens the belt, disconnect
the latch plate from the buckle, turn the buckle
around, and insert the latch plate into the buckle
again. If you still can’t make the child restraint secure,
try a different seating position.
Transporting Pets
Air Bags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision.
Pets should be restrained in the rear seat in pet harnesses
or pet carriers that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.Drive moderately during the first 500 miles (800 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided. Trailer tow is not recom-
mended during break in period.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur. For
the recommended viscosity and quality grades, refer to
“Maintenance Procedures” in “Maintaining Your Ve-
hicle”. NON-DETERGENT OR STRAIGHT MINERAL
OILS MUST NEVER BE USED.
