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.
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. 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 any 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.

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 Chrysler 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 Chrysler
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!
