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

SYMBOLS KEY
If you do not read the entire Owner’s Manual, you may miss important
information. Observe all Cautions and Warnings.
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 vehicles. 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 while some other vehicles may not.
Do not attempt sharp turns, abrupt maneuvers, or other unsafe driving actions
that can cause loss of vehicle control. Failure to operate this vehicle safely may
result in a collision, rollover of the vehicle, and severe or fatal injury. Drive
carefully.
Rollover Warning Label

Failure to use the driver and passenger seat belts provided is a major cause of
severe or fatal injury. In fact, the US government notes that the universal use
of existing seat belts could cut the highway death toll by 10,000 or more each
year and could reduce disabling injuries by two million annually. In a rollover
crash, an unbelted person is significantly more likely to die than a person
wearing a seat belt. Always buckle up.
WARNING!
These statements apply to operating procedures
that could result in a collision, bodily injury and/or
death.
CAUTION! These statements apply to procedures that could
result in damage to your vehicle.
NOTE: A suggestion which will improve installation,
operation, and reliability. If not followed, may
result in damage.
TIP: General ideas/solutions/suggestions on easier
use of the product or functionality.
