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.

could be seriously or fatally injured. Children should
be warned not to touch the parking brake, brake pedal
or the gear selector.

The engine only runs in the ON/RUN ignition position or
from a remote start request.
In case the ignition switch does not change with the push of
a button, the key fob may have a low or dead battery. In this
situation, a back up method can be used to operate the igni-
tion switch. Put the nose side (side opposite of the emer -
gency key) of the key fob against the START/STOP ignition
button and push to operate the ignition switch. Back Up Starting Method
NOTE:
The key fob may not be able to be detected by the vehicle
keyless-go system if it is located next to a mobile phone,
laptop or other electronic device; these devices may block the
key fob’s wireless signal and prevent the Keyless
Enter-N-Go system from starting the vehicle.
NOTE:
Refer to "Starting The Engine" in "Starting And Operating"
for further information.
• Do not leave the key fob in or near the vehicle, or in a
location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless
Enter-N-Go in the ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle.
• Do not leave children or animals inside parked vehicles in hot weather. Interior heat build-up may cause
serious injury or death.
CAUTION!
An unlocked vehicle is an invitation for thieves. Always
remove key fob from the vehicle and lock all doors when
leaving the vehicle unattended.

will remote start:
• Gear selector in PARK
• Doors closed
• Hood closed
• HAZARD switch off
• BRAKE switch inactive (brake pedal not pushed)
• Battery at an acceptable charge level
• PANIC button not pushed
• Fuel meets minimum requirement
• System not disabled from previous remote start event

(CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious injury or
death when inhaled.
• Keep key fobs away from children. Operation of the
Remote Start System, windows, door locks or other
controls could cause serious injury or death.

To Enter Remote Start Mode
Push and release the Remote Start button on the key fob
twice within five seconds. The parking lights will flash,
vehicle doors will lock, and the horn will chirp twice (if
programmed). Once the vehicle has started, the engine will
run for 15 minutes.
NOTE:
• If your power door locks were unlocked, Remote Start willautomatically lock the doors.
• If an engine fault is present or fuel level is low, the vehicle will start and then shut down in 10 seconds.
• The park lamps will turn on and remain on during Remote Start mode.
• For security, power window and power sunroof operation (if equipped) are disabled when the vehicle is in the
Remote Start mode.
• The engine can be started two consecutive times (two 15 minute cycles) with the key fob. However, the ignition
must be placed in the ON/RUN position before you can
repeat the start sequence for a third cycle.
To Exit Remote Start Mode Without Driving The
Vehicle
Push and release the remote start button one time or allow
the engine to run for the entire 15 minute cycle.
NOTE:
To avoid unintentional shutdowns, the system will disable
with a one time push of the remote start button for two
seconds after receiving a valid remote start request.
To Exit Remote Start Mode And Drive The Vehicle
Before the end of the 15 minute cycle, push and release the
unlock button on the key fob to unlock the doors and disarm
the vehicle security alarm system (if equipped). Then, prior
to the end of the 15 minute cycle, place the ignition in the
ON/RUN position.

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.
