UCONNECT SYSTEMS 
For detailed information about your Uconnect 
4/4C/4C NAV with 8.4-inch or 12-inch display, 
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 wireless 
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 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  computer 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.
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 
(US Residents) or www.driveuconnect.ca 
(Canadian Residents) to learn about 
available Uconnect software updates.
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 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 behavior, take your vehicle to your 
nearest authorized dealer immediately.
WARNING!
