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

before the engine will remote start:
Transmission 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
Water In Fuel Indicator Light is not illumi -
nated
Wait To Start Light Indicator Light is not illu -
minated
Malfunction Indicator Light is not illuminated
REMOTE START ABORT MESSAGE
The following messages will display in the
instrument cluster display if the vehicle fails to
remote start or exits remote start prematurely:
Remote Start Aborted — Door Open
Remote Start Aborted — Hood Open
Remote Start Aborted — Fuel Low
Remote Start Aborted — System Fault
The instrument cluster display message is
stored until the ignition is placed in the ON/RUN
position.
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 and the horn will chirp
twice (if programmed). In cold ambient
temperature conditions, the diesel vehicle may
delay crank up to 30 seconds for the Intake Air
Heater. Once the vehicle has started, the
engine will run for 15 minutes.
NOTE:
Crank may be delayed up to 75 seconds for
intake air heater operation at high altitudes,
and/or extreme cold.
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.

Additional features, such as windshield
wipers, will also not be available while 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 switch must be placed in
the ON/RUN position before you can repeat
the start sequence for a third cycle.

WARNING!
Do not start or run an engine in a closed
garage or confined area. Exhaust gas
contains Carbon Monoxide (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. Opera -
tion of the Remote Start System, windows,
door locks or other controls could cause
serious injury or death.

(Continued)
The vehicle security alarm is designed to protect
your vehicle. However, you can create
conditions where the system will give you a false
alarm. If one of the previously described arming
sequences has occurred, the vehicle security
alarm will arm regardless of whether you are in
the vehicle or not. If you remain in the vehicle
and open a door, the alarm will sound. If this
occurs, disarm the vehicle security alarm.
If the vehicle security alarm is armed and the
battery becomes disconnected, the vehicle
security alarm will remain armed when the
battery is reconnected; the exterior lights will
flash, and the horn will sound. If this occurs,
disarm the vehicle security alarm.
REARMING OF THE SYSTEM
If something triggers the alarm, and no action is
taken to disarm it, the vehicle security alarm will
turn the horn off after 29 seconds, 5 seconds
between cycles, up to 8 cycles if the trigger
remains active and then the vehicle security
alarm will rearm itself.

GETTING TO KNOW YOUR VEHICLE49

Rotate the headlight switch clockwise to the first
detent for parking light and instrument panel
light operation. Rotate the headlight switch to the
second detent for headlight, parking light, and
instrument panel light operation.

DAYTIME RUNNING LIGHTS (DRLS) — IF
E
QUIPPED
The headlights on your vehicle will illuminate
when the engine is started and the
transmission is in any gear except PARK. This
provides a constant "lights on" condition until
the ignition is placed in the OFF position. The
lights illuminate at less than half of normal
intensity. If the parking brake is applied, the
Daytime Running Lights (DRLs) will turn off.
Also, if a turn signal is activated, the DRL lamp
on the same side of the vehicle may turn off for
the duration of the turn signal activation. Once
the turn signal is no longer active, the DRL lamp
will illuminate.
NOTE:
If allowed by law in the country in which the
vehicle was purchased, the Daytime Running
Lights can be turned on and off using the Ucon -
nect system, refer to “Uconnect Settings” in
“Multimedia” for further information.
HIGH/LOW BEAM SWITCH
Push the multifunction lever toward the
instrument panel to switch the headlights to
high beam. Pulling the multifunction lever back
toward the steering wheel will turn the low
beams back on, or shut the high beams off.
AUTOMATIC HIGH BEAM HEADLAMP
C
ONTROL — IF EQUIPPED

The Automatic High Beam Headlamp Control
system provides increased forward lighting at
night by automating high beam control through
the use of a digital camera mounted on the inside
rearview mirror or forward facing camera. This
camera detects vehicle specific light and
automatically switches from high beams to low
beams until the approaching vehicle is out of view.

NOTE:
The Automatic High Beam Headlamp Control
can be turned on or off by selecting “ON”
under “Auto Dim High Beams” within your
Uconnect settings, as well as turning the
headlight switch to the AUTO position. Refer
to “Uconnect Settings” in “Multimedia” for
further information.

Broken, muddy, or obstructed headlights
and taillights of vehicles in the field of view
will cause headlights to remain on longer
(closer to the vehicle). Also, dirt, film, and
other obstructions on the windshield or
camera lens will cause the system to func -
tion improperly.

To opt out of the Advanced Auto High Beam
Sensitivity Control (default) and enter
Reduced High Beam Sensitivity Control (not
recommended), on vehicles equipped with
mirror controlled automatic high beams and
without the forward facing camera, toggle the
high beam lever six full on/off cycles within
10 seconds of placing the ignition in the ON
position. The system will return to the default
setting when the ignition is OFF.
If the windshield or Automatic High Beam
Headlamp Control mirror is replaced, the mirror
must be re-aimed to ensure proper
performance. See a local authorized dealer.
