CYBERSECURITY
Your vehicle may be a connected vehicle and
may be equipped with both wired and wire-
less networks. These networks allow your ve-
hicle to send and receive information. This
information allows systems and features in
your vehicle to function properly.
Your vehicle may be equipped with certain
security features to reduce the risk of unau-
thorized and unlawful access to vehicle sys-
tems and wireless communications. Vehicle
software technology continues to evolve over
time and FCA US LLC, working with its sup-
pliers, evaluates and takes appropriate steps
as needed. Similar to a computer or other
devices, your vehicle may require software
updates to improve the usability and perfor-
mance of your systems or to reduce the po-
tential risk of unauthorized and unlawful ac-
cess 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 allof the possible outcomes if your vehi-
cle’s systems are breached. It may be
possible that vehicle systems, including
safety related systems, could be im-
paired 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 soft-
ware, and if installed in your vehicle, it
may increase the possibility for vehicle
systems to be breached.
• As always, if you experience unusual
vehicle behavior, take your vehicle to
your nearest authorized dealer immedi-
ately. 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/
support/software-update.html to learn
about available Uconnect software up-
dates.
– Only connect and use trusted media
devices (e.g. personal mobile phones,
USBs, CDs).
Privacy of any wireless and wired communi-
cations cannot be assured. Third parties may
unlawfully intercept information and private
communications without your consent. For
further information, refer to “ “Onboard Di-
agnostic System (OBD II) Cybersecurity” in
“Getting To Know Your Instrument Panel” in
your Owner’s Manual.
