The driver’s primary responsibility is the safe operation of the vehicle. Driving while distracted can result in loss of vehicle control,

resulting in an accident and personal injury. FCA US LLC strongly recommends that the driver use extreme caution when using any

device or feature that may take their attention o the road. Use of any electrical devices, such as cellular telephones, computers, portable

radios, vehicle navigation or other devices, by the driver while the vehicle is moving is dangerous and could lead to a serious accident.

Texting while driving is also dangerous and should never be done while the vehicle is moving. If you ﬁnd yourself unable to devote your

full attention to vehicle operation, pull o the road to a safe location and stop your vehicle. Some states or provinces prohibit the use of

cellular telephones or texting while driving. It is always the driver’s responsibility to comply with all local laws.

This Owner’s Manual has been prepared to help you get acquainted with your new Jeep

®

brand vehicle and to provide a convenient

reference source for common questions.

Not all features shown in this manual may apply to your vehicle. For additional information, visit mopar.com/om (U.S.), owners.mopar.ca

(Canada) or your local Jeep

®

brand dealer.

Drunk driving is one of the most frequent causes of accidents. Your driving ability can be seriously

impaired with blood alcohol levels far below the legal minimum. If you are drinking, don’t drive.

Ride with a designated non-drinking driver, call a cab, a friend or use public transportation.

DRIVING AND ALCOHOL

Driving after drinking can lead to an accident. Your perceptions are less sharp, your reﬂexes are

slower and your judgment is impaired when you have been drinking. Never drink and then drive.

WARNING!

WARNING: Operating, servicing and maintaining a passenger vehicle or o-highway

motor vehicle can expose you to chemicals including engine exhaust, carbon monoxide,

phthalates, and lead, which are known to the State of California to cause cancer and birth

defects or other reproductive harm. To minimize exposure, avoid breathing exhaust,

do not idle the engine except as necessary, service your vehicle in a well-ventilated area

and wear gloves or wash your hands frequently when servicing your vehicle. For more

information go to www.P65Warnings.ca.gov/passenger-vehicle.

INTRODUCTION

Dear Customer,

Congratulations on the purchase of your new 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 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 this 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 Ú page 211.

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, which may or may not be applicable to your vehicle, will be identified with the wording "If Equipped" or, if applicable, refer

to the “Hybrid Supplement” for additional information. 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 authorized dealers know your Jeep® best, have factory-trained technicians, genuine Mopar® parts, and care about

your satisfaction.

If you do not read this 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 are against operating

procedures that could result in a collision, bodily

injury and/or death.

CAUTION!

These statements are against 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:

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 swing gate 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 on and the vehicle moving at

2 mph (4 km/h), all RKE commands are

disabled.

Key Fob

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 efficiency of the electronic devices

inside of the key fob, avoid exposing the key fob

to direct sunlight.

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 460.

To Lock/Unlock The Doors And Swing Gate

Push and release the unlock button on the key fob

once to unlock the driver’s door, or twice to unlock

all the doors and swing gate. 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 the Uconnect

Settings Ú page 220.

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/hazard-

ouswaste/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 press.

1. Remove the back cover of the fob by inserting

a flat-blade screwdriver into the slot on the

bottom of the fob. Pry until the cover unsnaps

being careful not to damage the seal. Proceed

counter-clockwise to pry 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 up being careful not to damage the

electronic board underneath.

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.

Duplication of key fobs may be performed at an

authorized dealer. This procedure consists of

programming a blank key fob to the vehicle

electronics.

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.

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 will shut the engine off in two seconds if an

invalid key fob is used to start the engine.

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 used an invalid key fob to start the

engine. Either of these conditions will result in the

engine being 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.

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 ignition in the

OFF position.
