INTRODUCTION
Dear Customer, congratulations on selecting your new 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 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, transmission, 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 Operating” 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 Warranty Information, and customer-oriented documents. Within this information, you will find a description of
the services that FCA US LLC offers to its customers, the vehicle's warranty coverage, 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,
recommendations, 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 Information, that may or may not be applicable to your vehicle, will 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 US LLC 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 information, contact an authorized dealer.
When it comes to service, remember that an authorized dealer knows your vehicle best, has factory-trained technicians and genuine MOPAR® parts,
and cares about your satisfaction.1

TECHNICAL SPECIFICATIONS
IDENTIFICATION DATA
VEHICLE IDENTIFICATION NUMBER
The Vehicle Identification Number (VIN) is found
on the left front corner of the instrument panel,
visible through the windshield.
Vehicle Identification Number

NOTE:
It is illegal to remove or alter the VIN.
BRAKE SYSTEM
If power assist is lost for any reason (for
example, repeated brake applications with the
engine off), the brakes will still function. However, you will experience a substantial
increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses
normal braking capability, the remaining
system will still function with some loss of
overall braking effectiveness. This will be
evident by increased pedal travel during
application, greater pedal force required to slow
or stop, and activation of the “Brake Warning
Light” and/or the “ABS Warning Light” during
brake use.
HYDRAULIC BRAKE ASSIST — IF
E
QUIPPED
The brake system power assist is provided by a
hydro-boost unit which shares fluid with the
power steering system. You may experience
some clicking or hissing noises from the
hydro-boost system during hard braking
conditions.
NOTE:
Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid
reaches operating temperature.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to
the vehicle. Any time a wheel has been removed
and reinstalled on the vehicle, the lug nuts/
bolts should be torqued using a properly
calibrated torque wrench using a high quality six
sided (hex) deep wall socket.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended
lug nuts/bolts and clean or remove any dirt or
oil before tightening.
