2023 JEEP GLADIATOR engine

WARNING: Operating, servicing and maintaining a passenger vehicle or off-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.
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
off 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 off 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 (USA), owners.mopar.ca (Canada) or your

DRIVING AND ALCOHOL
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 rideshare, a friend or use public transportation.
WARNING
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.
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 this vehicle. Please disregard any features and
equipment described in this manual that are not on this vehicle.

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
