CYBERSECURITY
Your vehicle may be a connected vehicle and may be
equipped with both wired and wireless networks. These
networks allow your vehicle to send and receive informa-
tion. This information allows systems and features in your
vehicle to function properly.
Your vehicle may be equipped with certain security fea-
tures to reduce the risk of unauthorized and unlawful
access to vehicle systems and wireless communications.
Vehicle software technology continues to evolve over time
and FCA US LLC, working with its suppliers, evaluates
and takes appropriate steps as needed. Similar to a com-
puter or other devices, your vehicle may require software
updates to improve the usability and performance of your
systems or to reduce the potential risk of unauthorized and
unlawful access to your vehicle systems.
The risk of unauthorized and unlawful access to your
vehicle systems may still exist, even if the most recent
version of vehicle software (such as Uconnect software) is
installed.
WARNING!
•It is not possible to know or to predict all of the
possible outcomes if your vehicle’s systems are
breached. It may be possible that vehicle systems,
including safety related systems, could be impaired
or a loss of vehicle control could occur that may
result in an accident involving serious injury or
death.
• ONLY insert media (e.g., USB, SD card, or CD) into
your vehicle if it came from a trusted source. Media
of unknown origin could possibly contain malicious
software, and if installed in your vehicle, it may
increase the possibility for vehicle systems to be
breached.
• As always, if you experience unusual vehicle behav-
ior, take your vehicle to your nearest authorized
dealer immediately.

NOTE:
•FCA US LLC or your dealer may contact you directly
regarding software updates.
• To help further improve vehicle security and minimize
the potential risk of a security breach, vehicle owners
should:
• Routinely check www.driveuconnect.com/software-
update to learn about available Uconnect software
updates.
• Only connect and use trusted media devices (e.g.
personal mobile phones, USBs, CDs).
Privacy of any wireless and wired communications cannot
be assured. Third parties may unlawfully intercept infor-
mation and private communications without your consent.
For further information, refer to “Data Collection & Pri-
vacy” in “Uconnect + SiriusXM Guardian” in your
Uconnect Owner’s Manual Supplement and “Onboard
Diagnostic System (OBD II) Cybersecurity” in “Getting To
Know Your Instrument Panel”.UCONNECT SETTINGS
The Uconnect system uses a combination of buttons on the
touchscreen and buttons on the faceplate located on the
center of the instrument panel that allows you to access
