INSTALLATION OF RADIO TRANSMITTING
EQUIPMENT
Special design considerations are incorporated into this
vehicle’s electronic system to provide immunity to radio
frequency signals. Mobile two-way radios and telephone
equipment must be installed properly by trained person-
nel. The following must be observed during installation.
The positive power connection should be made directly
to the battery and fused as close to the battery as possible.
The negative power connection should be made to body
sheet metal adjacent to the negative battery connection.
This connection should not be fused.
Antennas for two-way radios should be mounted on the
roof or the rear area of the vehicle. Care should be used
in mounting antennas with magnet bases. Magnets may
affect the accuracy or operation of the compass on
vehicles so equipped.
The antenna cable should be as short as practical and
routed away from the vehicle wiring when possible. Use
only fully shielded coaxial cable.
Carefully match the antenna and cable to the radio to
ensure a low Standing Wave Ratio (SWR). Mobile radio equipment with output power greater than
normal may require special precautions.
All installations should be checked for possible interfer-
ence between the communications equipment and the
vehicle’s electronic systems.
WARNING:
Operating, servicing and maintaining a
passenger vehicle or off-road highway
motor vehicle can expose you to chemicals
including engine exhaust, carbon monoxide,
phthalates, and lead, which are known to
the State of California to cause cancer and
birth defects or other reproductive harm.
To minimize exposure, avoid breathing
exhaust, do not idle the engine except as
necessary, service your vehicle in a
well-ventilated area and wear gloves or
wash your hands frequently when servicing
your vehicle. For more information go to

DRIVING AND ALCOHOL
Drunken driving is one of the most frequent causes of
accidents.
Your driving ability can be seriously impaired with blood
alcohol levels far below the legal minimum. If you are
drinking, don’t drive. Ride with a designated non-
drinking driver, call a cab, a friend, or use public trans-
portation.
WARNING!
Driving after drinking can lead to an accident.
Your perceptions are less sharp, your reflexes are
slower, and your judgment is impaired when you
have been drinking. Never drink and then drive. This manual illustrates and describes the operation of
features and equipment that are either standard or op-
tional on this vehicle. This manual may also include a
description of features and equipment that are no longer
available or were not ordered on this vehicle. Please
disregard any features and equipment described in this
manual that are not on this vehicle.
FCA US LLC reserves the right to make changes in design
and specifications, and/or make additions to or improve-
ments to its products without imposing any obligation
upon itself to install them on products previously manu-
factured.

INTRODUCTIONINTRODUCTION
Dear Customer, congratulations on selecting your new
vehicle. Be assured that it represents precision workman -
ship, 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 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, trans -
mission, and transfer case shifting. Learn how your vehicle
handles 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 the “Driving Tips” in “Starting and Oper -
ating” 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 supple -
mented by Warranty Information, and customer oriented
documents. In the attached Warranty Booklet you will find a
description of the services that FCA offers to its customers,
the Warranty Certificate and 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, recom -
mendations, tips, and important warnings in this manual
will help assure 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 which is related to
the trim level, engine, and version that you have purchased.
Any content introduced throughout the Owner’s Informa -
tion, that may or may not be applicable to your vehicle, will

INTRODUCTION 13
be identified with the wording “If Equipped”. All data
contained in this publication are intended to help you use
your vehicle in the best possible way. FCA aims at 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 informa -
tion, contact an authorized dealer.
If applicable, refer to the Owner’s Manual Supplement for
related information.
NOTE:
After reviewing the Owner’s Information, it should be stored
in the vehicle for convenient referencing, and remain with
the vehicle when sold.
When it comes to service, remember that your authorized
dealer knows your vehicle best, has factory-trained techni -
cians and genuine MOPAR® parts, and cares about your
satisfaction. HOW TO USE THIS MANUAL

This Owner’s Manual contains WARNINGS against oper -
ating procedures that could result in a collision, bodily injury
and/or death. It also contains CAUTIONS against proce -
dures that could result in damage to your vehicle. If you do

important information. Observe all Warnings and Cautions.
VAN CONVERSIONS/CAMPERS
The New Vehicle Limited Warranty does not apply to body
modifications or special equipment installed by van conver -
sion/camper manufacturers/body builders. U.S. residents

VEHICLE MODIFICATIONS/ALTERATIONS
WARNING!
Any modifications or alterations to this vehicle could
seriously affect its roadworthiness and safety and may
lead to a collision resulting in serious injury or death.

GETTING TO KNOW YOUR VEHICLE 29
If the vehicle security light turns on during normal vehicle
operation (vehicle running for longer than ten seconds), 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.
All of the key fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Key Programming
Programming key fobs may be performed at an authorized
dealer. 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.
NOTE:
Duplication of key fobs may be performed at an authorized
dealer. This procedure consists of programming a blank key
fob to the vehicle electronics. A blank key fob is one that has
never been programmed.
When having the Sentry Key Immobilizer System serviced,
bring all vehicle keys with you to an authorized dealer.CAUTION!
The Sentry Key Immobilizer system is not compatible
with some aftermarket remote starting systems. Use of
these systems may result in vehicle starting problems
and loss of security protection. CAUTION!
• Always remove the key fobs from the vehicle and lock
all doors when leaving the vehicle unattended.
• For vehicles equipped with Keyless Enter-N-Go —
Ignition, always remember to place the ignition in the
OFF position. 2
