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

SYMBOLS KEY
If you do not read the entire Owner’s Manual, you may miss important 
information. Observe all Cautions and Warnings.
ROLLOVER WARNING 
Utility vehicles have a significantly higher rollover rate than other types of 
vehicles. This vehicle has a higher ground clearance and a higher center of 
gravity than many passenger vehicles. It is capable of performing better in a 
wide variety of off-road applications. Driven in an unsafe manner, all vehicles 
can go out of control. Because of the higher center of gravity, if this vehicle is 
out of control it may roll over while some other vehicles may not.
Do not attempt sharp turns, abrupt maneuvers, or other unsafe driving actions 
that can cause loss of vehicle control. Failure to operate this vehicle safely may 
result in a collision, rollover of the vehicle, and severe or fatal injury. Drive 
carefully.
Rollover Warning Label
Failure to use the driver and passenger seat belts provided is a major cause of 
severe or fatal injury. In fact, the US government notes that the universal use 
of existing seat belts could cut the highway death toll by 10,000 or more each 
year and could reduce disabling injuries by two million annually. In a rollover 
crash, an unbelted person is significantly more likely to die than a person 
wearing a seat belt. Always buckle up.
WARNING!
These statements apply to operating procedures 
that could result in a collision, bodily injury and/or 
death.
CAUTION! These statements apply to procedures that could 
result in damage to your vehicle. 
NOTE: A suggestion which will improve installation, 
operation, and reliability. If not followed, may 
result in damage.
TIP: General ideas/solutions/suggestions on easier 
use of the product or functionality.

GETTING TO KNOW YOUR VEHICLE
KEYS 
KEY FOB
Your vehicle is equipped with a key fob which 
supports Passive Entry, Remote Keyless Entry 
(RKE), Keyless Enter ‘n Go™ (if equipped), and 
Remote Start (if equipped). The key fob allows you to 
lock or unlock the doors and tailgate from distances 
up to approximately 66 ft (20 m). The key fob does 
not need to be pointed at the vehicle to activate the 
system. The key fob also contains a mechanical key.
NOTE:
The key fob’s wireless signal may be blocked if 
the key fob is located next to a mobile phone, 
laptop, or other electronic device. This may 
result in poor performance.
With the ignition in the ON/RUN position, and 
the vehicle moving at 2 mph (4 km/h), all RKE commands are disabled.
Key Fob
NOTE:
In case the ignition switch does not change with 
the push of a button, the key fob may have a low 
or fully depleted battery. A low key fob battery 
condition may be indicated by a message in the 
instrument cluster display, or by the LED light on 
the key fob. If the LED key fob light no longer illu-
minates from key fob button pushes, then the 
key fob battery requires replacement.
Improper disposal of key fob batteries may be 
harmful to the environment. Please see an 
authorized dealer for proper battery disposal  
Ú page 432.
WARNING!
Push the Mechanical Key Release Button only 
with the key fob facing away from your body, 
especially your eyes and objects that may be 
damaged, such as clothing.
CAUTION!
The electrical components inside of the key fob 
may be damaged if the key fob is subjected to 
strong electrical shocks. In order to ensure 
complete effectiveness of the electronic devices 
inside of the key fob, avoid exposing the key fob 
to direct sunlight.

To Lock/Unlock The Doors And Tailgate
Push and release the unlock button on the key fob 
once to unlock the driver’s door, or twice to unlock 
all the doors. To lock all the doors, push the lock 
button once.
When the doors are unlocked, the turn signals will 
flash and the illuminated entry system will be 
activated. When the doors are locked, the turn 
signals will flash and the horn will chirp.
NOTE:
All doors can be programmed to unlock on the 
first push of the unlock button through 
Uconnect Settings  Úpage 215.
The mechanical flip key can be used to lock or 
unlock the doors, tailgate, glove compartment, 
storage compartments (if equipped), and rear 
seatbacks.
Key Left Vehicle Feature
If a valid key fob is no longer detected inside the 
vehicle while the vehicle’s ignition system is in the 
ON/RUN or START position, the message “Key Fob 
Has Left The Vehicle” will be shown in the 
instrument cluster display along with an interior 
chime. An exterior audible and visual alert will also 
be activated to warn the driver. The vehicle’s horn will rapidly chirp three times 
along with a single flash of the vehicle’s exterior 
lights.
NOTE:
The doors have to be open and then closed in 
order for the vehicle to check for the presence of 
a key fob; the Key Left Vehicle feature will not 
activate until all of the doors are closed.
These alerts will not be activated in situations 
where the vehicle’s engine is left running with 
the key fob inside.
Replacing The Battery In The Key Fob
The recommended replacement battery is 
CR2450.
NOTE:
Customers are recommended to use a battery 
obtained from Mopar®. Aftermarket coin 
battery dimensions may not meet the original 
OEM coin battery dimensions.
Perchlorate material — special handling may 
apply. See www.dtsc.ca.gov/hazardouswaste/
perchlorate for further information.
Do not touch the battery terminals that are on 
the back housing or the printed circuit board.
When a key fob battery is low, a warning will be 
indicated on the vehicle’s instrument cluster, 
and the fob LED will no longer illuminate with a 
button push.
1. Remove the back cover of the key fob by  inserting a flat-blade screwdriver into the slot 
on the bottom of the fob. Apply light pressure 
until the cover unsnaps being careful not to 
damage the seal. Proceed counterclockwise 
(in the order shown in the following image) to 
loosen the remaining snaps until the battery 
cover can be removed.

2. Remove the depleted battery by inserting a  small flat-blade screwdriver into the battery 
removal slot and sliding the battery forward 
and upward being careful not to damage the 
electronic board underneath.
Battery Replacement
3. Install the new battery into the key fob, making  sure the positive (+) side is facing up. Slide the 
battery until it is seated securely below the 
tabs.
4. Reassemble the back cover making sure it is  properly aligned before snapping it back in 
place.
Programming And Requesting Additional 
Key Fobs   
Programming the key fob may be performed by an 
authorized dealer.
NOTE:
Once a key fob is programmed to a vehicle, it 
cannot be repurposed and reprogrammed to 
another vehicle.
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. 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.
NOTE:
When having the Sentry Key Immobilizer system 
serviced, bring all vehicle keys with you to an 
authorized dealer.
Keys must be ordered to the correct key cut to 
match the vehicle locks.
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.
WARNING!
The integrated key fob contains a coin cell 
battery. Do not ingest the battery; there is a 
chemical burn hazard. If the coin cell battery is 
swallowed, it can cause severe internal burns 
in just two hours and can lead to death.
If you think a battery may have been swal-
lowed or placed inside any part of the body, 
seek immediate medical attention.
Keep new and used batteries away from chil
-
dren. If the battery compartment does not 
close securely, stop using the product and 
keep it away from children.
WARNING!
Always remove the key fobs from the vehicle 
and lock all doors when leaving the vehicle 
unattended.
Always remember to place the Keyless 
Enter ‘n Go™ Ignition in the OFF position when 
exiting the vehicle.2
23_JT_OM_EN_USC_t.book  Page 17   
Page 20 of 448
18GETTING TO KNOW YOUR VEHICLE  
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 addition, if the light 
begins to flash after the bulb check, it indicates 
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 electronics, 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  
Ú
page 432.
NOTE:A key fob that has not been programmed is also 
considered an invalid key.
IGNITION SWITCH  
KEYLESS ENTER ‘N GO™ IGNITION
This feature allows the driver to operate the 
ignition switch with the push of a START/STOP 
ignition button as long as the key fob is in the 
passenger compartment.
The START/STOP ignition button has several 
operating modes that are labeled and will 
illuminate when in position. These modes are OFF, 
ACC, RUN, and START.
