2018 CHRYSLER 300 ECU

Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equipment
manufacturer ’s instructions. Use of safety chains is man-
datory. Attach a tow bar or other towing device to main
structural members of the vehicle, not to bumpers or
associated brackets. State and local laws regarding vehicles
under tow must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode, not the ACC mode.
If the key fob is unavailable, or the vehicle’s battery is
discharged, refer toManual Park Release in this section
for instructions on shifting the transmission out of PARK
for towing.
CAUTION!
• Do not use sling type equipment when towing.
Vehicle damage may occur.
• When securing the vehicle to a flat bed truck, do not
attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.
(Continued)
CAUTION! (Continued)
•The manufacturer does not recommend towing this
vehicle using a tow dolly. Vehicle damage may occur.
All Wheel Drive (AWD) Models
The manufacturer recommends towing your vehicle with
all four wheels OFF the ground using a flatbed.
If the transmission and driveline are operable, AWD mod-
els can also be towed with the ignition in the ON/RUN
mode, the transmission in NEUTRAL (not in PARK!), and
the rear wheels OFF the ground with no limitation on
speed or distance. Since the ignition MUST be in the
ON/RUN mode to tow in this manner, AWD vehicles must
be towed with ALL FOUR wheels OFF the ground (e.g. on
a flatbed truck) if the key fob is unavailable.
CAUTION!
• Towing this vehicle using any other method can
cause severe transmission and/or transfer case dam-
age.
• Damage from improper towing is not covered under
the New Vehicle Limited Warranty.

IN CASE OF EMERGENCY 337

Add enough fluid to bring the level up to the requirements
described on the brake fluid reservoir. With disc brakes,
fluid level can be expected to fall as the brake pads wear.
However, low fluid level may be caused by a leak and a
checkup may be needed.
Use only brake fluid that has been recommended by the
manufacturer, and has been kept in a tightly closed con-
tainer to avoid contamination from foreign matter or
moisture.
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.
WARNING!
•Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information. Using the
wrong type of brake fluid can severely damage your
brake system and/or impair its performance. The
proper type of brake fluid for your vehicle is also
identified on the original factory installed hydraulic
master cylinder reservoir.
(Continued)
WARNING! (Continued)
•To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.

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/support/
software-update.html (U.S. Residents) or www.driveu-
connect.ca (Canadian Residents) to learn about avail-
able 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 your Uconnect Owner ’s Manual Supplement or
“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
and change the customer programmable features.
