Dear Customer,
Congratulations on the purchase of your new vehicle. Be assured that it represents precision workmanship, distinctive styling, and high quality. 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

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 which is related to the trim level, engine, and version that you have purchased. Any
content introduced throughout the Owner’s Information, that may or may not be applicable to your vehicle, will be identified with the wording “If

Key Fob Battery Replacement

3. Remove the battery by turning the back cover over (battery facing downward) and
tapping it lightly on a solid surface such as
a table or similar surface, and then 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 because skin oils
may cause battery deterioration. If you
touch a battery, clean it with rubbing
alcohol.
4. To assemble the key fob case, snap the two halves together.
Programming 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.
Request For Additional Remote Controls
NOTE:
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
authorized 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
serviced, bring all vehicle keys with you to an
authorized dealer.General Information
