IN CASE OF EMERGENCY 493
4. Using the screwdriver or similar tool, push the ManualPark Release lever locking tab (just below the middle of
the lever) to the right.
5. While holding the locking tab in the disengaged position, pull the tether strap to rotate the lever rearward, until it
locks in place pointing towards the driver's seat. Release
the locking tab and verify that the Manual Park Release
lever is locked in the released position.
6. The vehicle is now out of PARK and can be towed. Release the parking brake only when the vehicle is
securely connected to a tow vehicle.
To Reset The Manual Park Release:
1. Push the locking tab to the right, to unlock the lever.
2. Rotate the Manual Park Release lever forward to its orig -
inal position, until the locking tab snaps into place to
secure the lever.
3. Pull gently on the tether strap to confirm that the lever is locked in its stowed position.
4. Re-install the access cover.IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the poten -
tial for overheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in NEUTRAL, but do not increase the engine idle speed while
preventing vehicle motion with the brakes.
NOTE:
There are steps that you can take to slow down an impending
overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning
the A/C off can help remove this heat.
• You can also turn the temperature control to maximum heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement to
the radiator and aids in removing heat from the engine
cooling system.

496 IN CASE OF EMERGENCY
Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other equip-
ment designed for this purpose, following equipment manu-
facturer’s instructions. Use of safety chains is mandatory.
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 to ”Manual Park Release” in this section for
instructions on shifting the transmission out of PARK for
towing.

SERVICING AND MAINTENANCE 527
(Continued)
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be checked
when performing under the hood service or immediately if
the brake system warning lamp indicates system failure.
If necessary, add fluid to bring level within the designated
marks on the side of the reservoir of the brake master
cylinder. Be sure to clean the top of the master cylinder area
before removing cap.With disc brakes the fluid level can be expected to fall as the
brake linings wear. However, an unexpected drop in fluid
level may be caused by a leak and a system check should be
conducted.
Refer to “Fluids And Lubricants” in “Technical Specifica
-
tions” for further information.
WARNING!
Riding the brakes can lead to brake failure and possibly
a collision. Driving with your foot resting or riding on
the brake pedal can result in abnormally high brake
temperatures, excessive lining wear, and possible brake
damage. You would not have your full braking capacity
in an emergency.
WARNING!
• Use only manufacturer's recommended brake fluid. Refer to “Fluids And Lubricants” in “Technical Speci -
fications” 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.
• 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 cylinder
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 unexpect -
edly during hard or prolonged braking, resulting in
sudden 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 features
to reduce the risk of unauthorized and unlawful access to
vehicle systems and wireless communications. Vehicle soft -
ware technology continues to evolve over time and FCA US
LLC, working with its suppliers, evaluates and takes appro -
priate 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.

MULTIMEDIA 577
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 (U.S. Resi-
dents) 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).
Privacy of any wireless and wired communications cannot
be assured. Third parties may unlawfully intercept informa -
tion and private communications without your consent. For
further information, refer to “Data Collection & Privacy” in
your Uconnect Owner’s Manual Supplement or “Onboard
Diagnostic System (OBD II) Cybersecurity” in “Getting To
Know Your Instrument Panel”.
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.
