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 infor-
mation. 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 perfor-
mance of your systems or to reduce the potential risk of
unauthorized and unlawful access to your vehicle sys-
tems.
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!(Continued)
•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 mali-
cious 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 be-
havior, take your vehicle to your nearest authorized
dealer immediately. 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 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 can-
not 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 “Maintaining
Your Vehicle”.

WARNING!(Continued)
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and your foot is
firmly pressing the brake pedal.
• Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle always apply the
parking brake, shift the transmission into PARK,
turn the engine OFF, and remove the ignition key.
Once the key is removed, the transmission is
locked in PARK, securing the vehicle against un-
wanted movement.
• When leaving the vehicle, always remove the igni-
tion key from the vehicle and lock the vehicle.

WARNING!(Continued)
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have a collision.
• When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or dam-
age to the brakes, axle, engine, transmission, steer-
ing, suspension, chassis structure or tires.
• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to
the frame or hook retainers of the vehicle hitch.
Cross the chains under the trailer tongue and allow
enough slack for turning corners.
• Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on

WARNING!
•ONLY an authorized service technician should con-
nect equipment to the OBD II connection port in
order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the
OBD II connection port, such as a driver-behavior
tracking device, 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.
• Access, or allow others to access, information
stored in your vehicle systems, including per-
sonal information.
For further information, refer to “Cybersecurity” in the
“Understanding Your Instrument Panel” section.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is possibly loose, improp-
erly installed, or damaged. A “gASCAP” message will be
displayed in the odometer. Tighten the gas cap until a
clicking sound is heard. This is an indication that the
gas cap is properly tightened. Push the odometer reset
button to turn the message off. If the problem persists,
the message will appear the next time the vehicle is
started. This might indicate a damaged cap. If the prob-
lem is detected twice in a row, the system will turn on the
MIL. Resolving the problem will turn the MIL off.
