INTRODUCTION
INTRODUCTION
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 “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 located online. Within this information, you will
find a description of the services that FCA US LLC 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 instruc -
tions, 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.

SENTRY KEY
The Sentry Key Immobilizer system prevents unauthorized
vehicle operation by disabling the engine. The system does
not need to be armed or activated. Operation is automatic,
regardless of whether the vehicle is locked or unlocked.
The system uses a key fob, keyless push button ignition and
a Radio Frequency (RF) receiver to prevent unauthorized
vehicle operation. Therefore, only key fobs that are
programmed to the vehicle can be used to start and operate
the vehicle. The system cannot reprogram a key fob obtained
from another vehicle.
After placing the ignition switch in the ON/RUN position,
the vehicle security light will turn on for three seconds for a
bulb check. If the light remains on after the bulb check, it
indicates that there is a problem with the electronics. In addi-
tion, if the light begins to flash after the bulb check, it indi -
cates that someone attempted to start the engine with an
invalid key fob. In the event that a valid key fob is used to
start the engine but there is an issue with the vehicle elec -
tronics, the engine will start and shut off after two seconds. 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.
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.

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.
