INTRODUCTION
Dear Customer,
Congratulations on the purchase of your Jeep® vehicle. Be assured that it represents precision workmanship, distinctive styling, and high quality.
This is a specialized utility vehicle. It can go places and perform tasks that are not intended for conventional passenger vehicles. It handles and maneuvers
differently from many passenger vehicles, both on-road and off-road, so take time to become familiar with your vehicle. If equipped, the two-wheel drive version
of this vehicle is 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 operate this vehicle, read the Owner’s Manual. Be sure you are familiar with all vehicle controls, particularly those used for braking, steering,
transmission, and transfer case operation. Learn how your vehicle handles on different road surfaces. Your driving skills will improve with experience. When
driving off-road, or operating 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.
See Úpage 207 for further information.
This Owner’s Manual has been prepared with the assistance of service and engineering specialists to acquaint you with the operation and maintenance of your
vehicle. It is supplemented by customer-oriented documents. Within this information, you will find a description of the services that FCA US LLC offers to its
customers as well as the details of the terms and conditions for maintaining its validity. Please take the time to read all of these publications carefully before
driving your vehicle for the first time. Following the instructions, recommendations, tips, and important warnings in this manual will help ensure safe and
enjoyable operation of your vehicle.
This Owner’s Manual describes all versions of this vehicle. Options and equipment dedicated to specific markets or versions are not expressly indicated in the
text. Therefore, you should only consider the information that is related to the trim level, engine, and version that you have purchased. Any content introduced
throughout the Owner’s Information that may or may not be applicable to your vehicle will be identified with the wording “If Equipped”. All information contained
in this publication is intended to help you use your vehicle in the best possible way. FCA US LLC aims towards a constant improvement of the vehicles produced.
For this reason, it reserves the right to make changes to the model described for technical and/or commercial reasons. For further information, contact an
authorized dealer.
When it comes to service, remember that authorized dealers know your Jeep® best, have factory-trained technicians, genuine Mopar® parts, and care about
your satisfaction.1

20GETTING TO KNOW YOUR VEHICLE
NOTE:When opening the driver's door with the ignition in
the ON/RUN (engine not running) position, a chime
will sound to remind you to place the ignition in the
OFF position. In addition to the chime, the
message will display “Ignition Or Accessory On” in
the cluster.
REMOTE START — IF EQUIPPED
(GASOLINE)

This system uses the key fob to start the
engine conveniently from outside the
vehicle while still maintaining security.
The system has a range of 328 ft (100 m).

Remote Start is used to defrost windows in cold
weather, and to reach a comfortable climate in all
ambient conditions before the driver enters the
vehicle.
NOTE:
The vehicle must be equipped with an auto -
matic transmission to be equipped with Remote
Start.
Obstructions between the vehicle and key fob
may reduce this range Ú page 432.
HOW TO USE REMOTE START
Push and release the Remote Start button on the
key fob twice within five seconds. The vehicle
doors and tailgate will lock, the turn signals will
flash twice, and the horn will chirp twice (if
equipped). Pushing the Remote Start button again
will shut the engine off.
NOTE:
With Remote Start, the engine will only run for
15 minutes.
Remote Start can only be used twice.
If an engine fault is present or fuel level is low,
the vehicle will start and then shut down in
10 seconds.
The parking lights 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 ignition must be placed in the ON/RUN posi -
tion before the Remote Start sequence can be
repeated for a third cycle.
All of the following conditions must be met before
the engine will remote start:
Gear selector in PARK
Doors closed
Hood closed
Hazard switch off
Brake switch inactive (brake pedal not pressed)
Battery at an acceptable charge level
Panic button not pushed
System not disabled from previous Remote
Start event
CAUTION!
An unlocked vehicle is an invitation for thieves.
Always remove key fob from the vehicle and lock
all doors when leaving the vehicle unattended.
WARNING!
Do not start or run an engine in a closed
garage or confined area. Exhaust gas contains
carbon monoxide (CO) which is odorless and
colorless. Carbon monoxide is poisonous and
can cause serious injury or death when
inhaled.
Keep key fobs away from children. Operation
of the Remote Start system, windows, door
locks or other controls could cause serious
injury or death.

GETTING TO KNOW YOUR VEHICLE53
To operate HomeLink®, push and release any
of the programmed HomeLink® buttons. These
buttons will activate the devices they are
programmed to with each press of the corre -
sponding HomeLink® button.
The HomeLink® indicator light is located above
the center button.
NOTE:HomeLink® is disabled when the Vehicle Security
system is active Ú page 432.
BEFORE YOU BEGIN PROGRAMMING
H
OMELINK®
For efficient programming and accurate
transmission of the radio-frequency signal, it is
recommended that a new battery be placed in the
hand-held transmitter of the device that is being
programmed to the HomeLink® system. Make
sure your hand-held transmitter is programmed to
activate the device you are trying to program your
HomeLink® button to.
Ensure that your vehicle is parked outside of the
garage before you begin programming.
It is recommended that you erase all the channels
of your HomeLink® before you use it for the first
time.
ERASING ALL THE HOMELINK®
C
HANNELS
To erase the channels, follow this procedure:

1. Place the ignition switch into the ON/RUN
position.

2. Push and hold the two outside HomeLink® buttons (I and III) for up to 20 seconds, or until
the HomeLink® indicator light flashes.
NOTE:Erasing all channels should only be performed
when programming HomeLink® for the first time.
Do not erase channels when programming addi -
tional buttons.
IDENTIFYING WHETHER YOU HAVE A
R
OLLING CODE OR NON-ROLLING CODE
D
EVICE
Before programming a device to one of your
HomeLink® buttons, you must determine whether
the device has a rolling code or non-rolling code.
Rolling Code Devices
To determine if your device has a rolling code, a
good indicator is its manufacturing date. Typically,
devices manufactured after 1995 have rolling
codes. A device with a rolling code will also have a
“LEARN” or “TRAIN” button located where the antenna is attached to the device. The button may
not be immediately visible when looking at the
device. The name and color of the button may vary
slightly by manufacturer.
NOTE:The “LEARN” or “TRAIN” button is not the button
you normally use to operate the device.
Non-rolling Code Devices
Most devices manufactured before 1995 will not
have a rolling code. These devices will also not
have a “LEARN” or “TRAIN” button.
PROGRAMMING HOMELINK® TO A
G
ARAGE DOOR OPENER
To program any of the HomeLink® buttons to
activate your garage door opener motor, proceed
as follows:
NOTE:All HomeLink® buttons are programmed using this
procedure. You do not need to erase all channels
when programming additional buttons.

1. Place the ignition switch into the ON/RUN
position.

2. Place the garage door opener transmitter 1 to 3 inches (3 to 8 cm) away from the
HomeLink® button you wish to program, while
keeping the HomeLink® indicator light in view.
