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

22GETTING TO KNOW YOUR VEHICLE
For more information on ATC, MTC, and climate
control settings, see Ú page 61.
NOTE:These features will stay on through the duration of
Remote Start, or until the ignition is placed in the
ON/RUN position. The climate control settings will
change if manually adjusted by the driver while the
vehicle is in remote start mode. This includes
turning the climate controls off using the OFF
button.
REMOTE START WINDSHIELD WIPER
D
E-ICER ACTIVATION — IF EQUIPPED
When Remote Start is active and the outside
ambient temperature is less than 33°F (0.6°C),
the Windshield Wiper De-Icer will activate. Exiting
Remote Start will resume previous operation. If the
Windshield Wiper De-Icer was active, the
Windshield Wiper De-Icer timer and operation will
continue.
REMOTE START CANCEL MESSAGE
The following messages will display in the
instrument cluster if the vehicle fails to remote
start or exits Remote Start prematurely:
Remote Start Canceled — Door Open
Remote Start Canceled — Hood Open
Remote Start Canceled — Fuel Low
Remote Start Canceled — Tailgate Open
Remote Start Canceled — Time Expired
Remote Start Disabled — Start Vehicle To Reset
The message will stay active until the ignition is
placed in the ON/RUN position.
REMOTE START — IF EQUIPPED (DIESEL)
This system uses the key fob to start the
engine conveniently from outside the
vehicle while still maintaining security.
The system has a range of approximately
328 ft (100 m).
Remote Start is used to defrost windows in cold
weather, and to reach a comfortable climate in all
ambient conditions before the driver enters the
vehicle.
NOTE:
The vehicle must be equipped with an auto -
matic transmission to be equipped with Remote
Start.
Obstructions between the vehicle and the key
fob may reduce this range.
The Remote Start system will wait for the Wait
To Start yellow telltale to extinguish before
cranking the engine Ú page 132. This allows
time for the engine preheat cycle to heat the
cylinder air, and is normal in cold weather.
HOW TO USE REMOTE START
Push and release the Remote Start button on the
key fob twice within five seconds. The vehicle
doors and tailgate will lock, the turn signals will
flash twice, and the horn will chirp twice. Pushing
the Remote Start button again will shut the engine
off.
NOTE:
With Remote Start, the engine will only run for
15 minutes.
Remote Start can only be used twice.
If an engine fault is present or fuel level is low,
the vehicle will start and then shut down in 10
seconds.
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. Operation
of the Remote Start system, windows, door
locks or other controls could cause serious
injury or death.

Headlight Switch (Vehicles Sold In Canada)

NOTE:Vehicles sold in Canada are equipped with a head -
light switch with an AUTO and ON detent but
without an OFF detent. Headlights will be deacti -
vated when the headlight switch is placed in the
parking lights position. However, the Daytime
Running Lights (DRLs) will be activated along with
the front and rear marker lights. The DRLs may be
deactivated when the parking brake is engaged.
Rotate the headlight switch clockwise to the first
detent for parking lights and instrument panel light
operation. Rotate the headlight switch to the second detent for headlights, parking lights, and
instrument panel light operation.
NOTE:For vehicles sold in Canada, rotate the headlight
switch clockwise from the parking lights and
instrument panel light position to the first detent to
turn on headlights, parking lights, and instrument
panel light. Rotate the headlight switch to the
second detent for the AUTO position.
DAYTIME RUNNING LIGHTS (DRLS) —
I
F EQUIPPED
The Daytime Running Lights (DRLs) are in a
dedicated position below the headlight assembly.
DRLs are active when the low beams are not on
while the vehicle’s transmission is in any position
(automatic transmission), or when the vehicle
begins to move (manual transmission).
NOTE:
For vehicles sold in Canada, the DRLs will auto -
matically deactivate when the front fog lights
are turned on.
On some vehicles, the Daytime Running Lights
may deactivate, or reduce intensity, on one side
of the vehicle (when a turn signal is activated on
that side), or on both sides of the vehicle (when
the hazard warning lights are activated).
HIGH/LOW BEAM SWITCH
The High/Low Beam switch is located within the
multifunction lever on the left side of the steering
wheel. High beam headlights can be used for
improved visibility in low lit areas when there is no
oncoming traffic. Otherwise, it is recommended to
use the low beam headlights to reduce glare to
other vehicles.
With the headlight switch activated, push the
multifunction lever toward the instrument panel to
switch the headlights to high beams. The lever will
return to the centered position. To return the
headlights to low beam, pull the lever toward the
steering wheel, or push the lever toward the
instrument panel.

Oil Pressure Warning Light
This warning light will illuminate, and a
chime will sound, to indicate low engine
oil pressure. If the light and chime turn on
while driving, safely stop the vehicle and
turn off the engine as soon as possible. After the
vehicle is safely stopped, restart the engine and
monitor the Oil Pressure Warning Light. If the Oil
Pressure Warning Light is still illuminated, turn the
engine OFF and contact an authorized dealer for
further assistance. Do not operate the vehicle until
the cause is corrected. If the light is no longer
illuminated, the engine can be operated but it is
recommended to take the vehicle to an authorized
dealer as soon as possible.
Do not operate the vehicle until the cause is
corrected. This light does not indicate how much oil
is in the engine. The engine oil level must be
checked under the hood.
Oil Temperature Warning Light
This warning light will illuminate to
indicate the engine oil temperature is
high. If the light turns on while driving,
stop the vehicle and shut off the engine
as soon as possible. Wait for oil temperature to
return to normal levels.
Seat Belt Reminder Warning Light
This warning light indicates when the
driver or passenger seat belt is
unbuckled. When the ignition is first
placed in the ON/RUN or ACC/ON/RUN
position and if the driver’s seat belt is unbuckled,
a chime will sound and the light will turn on. When
driving, if the driver or front passenger seat belt
remains unbuckled, the Seat Belt Reminder Light
will flash or remain on continuously and a chime
will sound Ú page 299.
Rear Seat Belt Reminder Indicator Light —
If Equipped With A Base Instrument
Cluster
This light indicates when a rear seat belt
is unbuckled in the second row. When
the ignition is first placed in the ON/RUN
or ACC/ON/RUN position, and if a seat
belt in the second row is unbuckled, a light
corresponding to the specific seat will turn on in
the upper right portion of the instrument cluster
display, momentarily replacing the configurable
corner information. If a second row seat belt that
was buckled at the start of the trip is unbuckled,
the Rear Seat Belt Reminder Light will change from
the buckled to the unbuckled symbol, and a chime
will sound Ú page 299.
Transmission Temperature Warning
Light — If Equipped

This warning light will illuminate to warn of
a high transmission fluid temperature.
This may occur with strenuous usage such
as trailer towing. If this light turns on, stop
the vehicle and run the engine at idle or slightly
faster, with the transmission in PARK (P) or NEUTRAL
(N), until the light turns off. Once the light turns off,
you may continue to drive normally. If Manual
transmission equipped, this warning will illuminate
to warn of high clutch temperature. This may occur
with driver misuse of clutch pedal or resting foot on
the clutch pedal or partially engaging the clutch for
longer duration. If the light turns on, it will be with an
additional CLUTCH HOT message. Stop the vehicle
safely and run the engine at idle with transmission
gear in NEUTRAL (N) until the light turns off. Once the
light turns off, follow the message displayed in the
instrument cluster.
