UCONNECT SYSTEMS
For detailed information about your Ucon-
nect system, refer to your Uconnect Owner’s
Manual Supplement.
NOTE:
Uconnect screen images are for illustration
purposes only and may not reflect exact soft -
ware for your vehicle.
CYBERSECURITY
Your vehicle may be a connected vehicle and
may be equipped with both wired and wire -
less networks. These networks allow your
vehicle 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
systems and wireless communications.
Vehicle software technology continues to
evolve over time and FCA, working with its
suppliers, evaluates and takes appropriate
steps as needed. Similar to a computer or
other devices, your vehicle may require soft -
ware 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.
NOTE:
FCA or your dealer may contact you
directly regarding software updates.
To help further improve vehicle security
and minimize the potential risk of a secu
-
rity breach, vehicle owners should:
Only connect and use trusted media devices (e.g. personal mobile phones,
USBs, CDs). 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 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 immediately.
