LEATHER SURFACES
Mopar Total Clean is specifically recommended
for leather upholstery.

Your leather upholstery can be best preserved by
regular cleaning with a damp soft cloth. Small
particles of dirt can act as an abrasive and
damage the leather upholstery and should be
removed promptly with a damp cloth. Stubborn
soils can be removed easily with a soft cloth and
Mopar Total Clean. Care should be taken to avoid
soaking your leather upholstery with any liquid.
Please do not use polishes, oils, cleaning fluids,
solvents, detergents, or ammonia-based
cleaners to clean your leather upholstery.
NOTE:
If equipped with light colored leather, it tends to
show any foreign material, dirt, and fabric dye
transfer more so than darker colors. The leather
is designed for easy cleaning, and FCA recom
-
mends Mopar total care leather cleaner applied
on a cloth to clean the leather seats as needed.
GLASS SURFACES
All glass surfaces should be cleaned on a
regular basis with Mopar Glass Cleaner, or any
commercial household-type glass cleaner.
Never use an abrasive type cleaner. Use caution
when cleaning the inside rear window equipped
with electric defrosters or windows equipped
with radio antennas. Do not use scrapers or
other sharp instruments that may scratch the
elements.
When cleaning the rear view mirror, spray
cleaner on the towel or cloth that you are using.
Do not spray cleaner directly on the mirror.
CAUTION!
Do not use Alcohol and Alcohol-based and/or
Ketone based cleaning products to clean
leather upholstery, as damage to the
upholstery may result.

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 mopar.com/om
(U.S.), owners.mopar.ca (Canada) or your local Ram brand dealer.
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.

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.
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.
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.
