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.
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: If you are the first registered retail owner of your vehicle, you may obtain a complimentary printed copy of the Warranty Booklet by calling 1-800-247-9753 or by

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.

3. Remove the back cover to access and replace
the battery. When replacing the battery, match
the (+) sign on the battery to the (+) sign on the
inside of the battery clip, located on the back
cover. Avoid touching the new battery with your
fingers. Skin oils may cause battery deterio -
ration. If you touch a battery, clean it with
r u

bbing alcohol.
4. To assemble the key fob case, snap the two h
alves together.
Programming And Requesting Additional
Key Fobs
Programming the key fob may be performed by an
authorized dealer.
NOTE:
Once a key fob is programmed to a vehicle, it
cannot be repurposed and reprogrammed to
another vehicle.
Only key fobs that are programmed to the
vehicle electronics can be used to start and
operate the vehicle. Once a key fob is
programmed to a vehicle, it cannot be
programmed to any other vehicle.
Duplication of key fobs may be performed at an
a u

thorized dealer. This procedure consists of
programming a blank key fob to the vehicle
electronics. A blank key fob is one that has never
been programmed.
NOTE:
When having the Sentry Key Immobilizer system
s e
rviced, bring all vehicle keys with you to an
authorized dealer.
SENTRY KEY
The Sentry Key Immobilizer system prevents
unauthorized vehicle operation by disabling the
engine. The system does not need to be armed or
activated. Operation is automatic, regardless of
whether the vehicle is locked or unlocked.
The system uses a key fob, keyless push button
i g

nition and a Radio Frequency (RF) receiver to
prevent unauthorized vehicle operation. Therefore,
only key fobs that are programmed to the vehicle
can be used to start and operate the vehicle. The
system cannot reprogram a key fob obtained from
another vehicle.
After placing the ignition switch in the ON/RUN
p os

ition, the Vehicle Security Light will turn on for
three seconds for a bulb check. If the light remains
on after the bulb check, it indicates that there is a
problem with the electronics. In addition, if the light
begins to flash after the bulb check, it indicates
that someone attempted to start the engine with
an invalid key fob. In the event that a valid key fob
is used to start the engine but there is an issue
with the vehicle electronics, the engine will start
and shut off after two seconds.
WARNING!
The integrated key fob contains a coin cell
battery. Do not ingest the battery; there is a
chemical burn hazard. If the coin cell battery is
swallowed, it can cause severe internal burns
in just two hours and can lead to death.
If you think a battery may have been swal-
lowed or placed inside any part of the body,
s e
ek immediate medical attention.
Keep new and used batteries away from chil -
dren. If the battery compartment does not
c l
ose securely, stop using the product and
keep it away from children.
WARNING!
Always remove the key fobs from the vehicle
and lock all doors when leaving the vehicle
unattended.
Always remember to place the Keyless Enter
‘n Go™ — Ignition in the OFF position.
