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.

This Owner’s Manual illustrates and describes the operation of features and equipment that are either standard or optional on this

vehicle. This manual may also include a description of features and equipment that are no longer available or were not ordered on

right to make changes in design and speciﬁcations, and⁄or make additions to or improvements to its products without imposing any

obligation upon itself to install them on products previously manufactured.

With respect to any vehicles sold in Canada, the name FCA US LLC shall be deemed to be deleted and the name FCA Canada Inc.

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.

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 Ú page 225 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.

SYMBOLS KEY

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.

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.

CAMPERS

This vehicle is NOT recommended for slide-in camper applications.

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 on and the vehicle moving at

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

disabled.

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.

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 informa-

tion.

 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 illumi-

nate with a button push.

1. Remove the back cover of the key fob by

inserting a flat-blade screw driver into the

slot on the bottom of the fob. Apply light

pressure until the cover unsnaps being

careful not to damage the seal. Proceed

counter-clockwise (in the order shown

below) to loosen the remaining snaps until

the battery cover can be removed.

1-3 – Back Cover Pry Points

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.

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.
