INTRODUCTION
Dear Customer,
Congratulations on the purchase of your new Ram. 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 the 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 Úpage 188.
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”. 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 Ram best, have factory-trained technicians, genuine Mopar® parts, and care about your
satisfaction.1
