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 Ram brand vehicle and to provide a convenient reference for common questions.
Not all features shown in this manual may apply to your vehicle. For additional information on accessories to help personalize your vehicle, visit
www.mopar.com/en-us/care/owners-manual.html (U.S.), www.owners.mopar.ca (Canada) or your local Ram brand dealer.
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 friend or use public transportation.
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 that are no longer available or were not ordered on this vehicle. FCA US LLC reserves the 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 vehicles sold in Canada, the name FCA US LLC shall be deemed to be deleted and the name FCA Canada Inc. used in substitution therefore.
If you are the first registered retail owner of your vehicle, you may obtain a complimentary printed copy of the Warranty Booklet by calling
1-866-726-4636 (U.S.) or 1-800-387-1143 (Canada), or by contacting your dealer.
This Owner’s Manual is intended to familiarize you with the important features of your vehicle. Your most up-to-date Owner’s Manual, Navigation/Uconnect manuals and Warranty Booklet can be found by visiting the website on the back cover. U.S. residents can purchase replacement kits by visiting
www.techauthority.com and Canadian residents can purchase replacement kits by calling 1-800-387-1143.
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.
