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

AdBlue® (UREA) Injection System Failure
Warning Light — If Equipped
This warning light will illuminate along
with a dedicated message on the display
(if equipped) if an unknown fluid not
conforming with acceptable
characteristics is inserted, or if an average
consumption of AdBlue® (UREA) over 50% is
detected. Contact an authorized dealer as soon as
possible. If the problem is not solved, a specific message will
appear on the Instrument Cluster Display
whenever a certain threshold is reached until it will
no longer be possible to start the engine.

continuous dedicated message will appear on the
instrument panel, accompanied by a buzzer sound
(if equipped).
YELLOW INDICATOR LIGHTS
4WD Indicator Light — If Equipped
This light alerts the driver that the vehicle
is in the four-wheel drive mode, and the
front and rear driveshafts are
mechanically locked together forcing the
front and rear wheels to rotate at the same speed.
4WD Low Indicator Light — If Equipped
This light alerts the driver that the vehicle
is in the 4WD Low mode. The front and
rear driveshafts are mechanically locked
together forcing the front and rear
wheels to rotate at the same speed. Low range
provides a greater gear reduction ratio to provide
increased torque at the wheels.
4WD Part Time Indicator Light —
If Equipped
This light alerts the driver that the vehicle
is in the four-wheel drive part time mode,
and the front and rear driveshafts are
mechanically locked together forcing the
front and rear wheels to rotate at the same speed.
Axle Locker Fault Indicator Light —
If Equipped
This light indicates when front and/or
rear axle locker fault has been detected.
Rear Axle Lock Indicator Light —
If Equipped
This light indicates when the rear axle
lock has been activated Ú page 161.
Front And Rear Axle Lock Indicator Light —
If Equipped
This light indicates when the front, rear,
or both axles have been locked. The
telltale will display the lock icon on the
front and rear axles to indicate the
current lock status.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may result
when using replacement equipment that is not
of the same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket
tire sealant it is recommended that you take
your vehicle to an authorized dealer to have your
sensor function checked.

damage, and please see an authorized dealer.
GREEN INDICATOR LIGHTS
4WD Auto Indicator Light — If Equipped
This light alerts the driver that the
vehicle is in the four-wheel drive auto
mode. The system will provide power to
all four wheels and shift the power
between the front and rear axles as needed. This
will provide maximum traction in dry and slippery
conditions.
Cruise Control SET Indicator Light —
If Equipped With A Premium Instrument
Cluster
This indicator light will illuminate when
the cruise control is set to the desired
speed Ú page 173.
CAUTION!
The presence of water in the fuel system circuit
may cause severe damage to the injection
system and irregular engine operation. If the
indicator light is illuminated, contact an
authorized dealer as soon as possible to bleed
