Adaptive Cruise Control (ACCyfLVDFRQYe-
nience system. It is not a substitute for
active driver involvement. It is always the
driver’s responsibility to be attentive of
road, traffic, and weather conditions,
vehicle speed, distance to the vehicle
ahead; and, most importantly, brake opera -
tion to ensure safe operation of the vehicle
under all road conditions. Your complete
attention is always required while driving to
maintain safe control of your vehicle.
Failure to follow these warnings can result
in a collision and death or serious personal
injury.
The ACC system:
Does not react to pedestrians,
oncoming vehicles, and stationary
objects (e.g., a stationary vehicle in a
traffic jam or a disabled vehicleyf.
Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance
conditions.

WARNING!
To prevent serious injury or death:
Always remain alert and be ready to take
control of the vehicle in the event that the
Active Driving Assist system disables.
Always keep your hands on the steering
wheel when the Active Driving Assist
system is activated.
Maintain a safe distance from other vehi-
cles and pay attention to traffic conditions.

Drivers must be careful when backing up
even when using ParkSense. Always check
carefully behind your vehicle, look behind
you, and be sure to check for pedestrians,
animals, other vehicles, obstructions, and
blind spots before backing up. You are
responsible for safety and must continue to
pay attention to your surroundings. Failure
to do so can result in serious injury or
death.
Before using ParkSense, it is strongly
recommended that the ball mount and
hitch ball assembly be disconnected from
the vehicle when the vehicle is not used for
towing. Failure to do so can result in injury
or damage to vehicles or obstacles
because the hitch ball will be much closer
to the obstacle than the rear fascia when
the vehicle sounds the continuous tone.
Also, the sensors could detect the ball
mount and hitch ball assembly, depending
on its size and shape, giving a false indica-
tion that an obstacle is behind the vehicle.
CAUTION!
ParkSense is only a parking aid and it is
unable to recognize every obstacle,
including small obstacles. Parking curbs
might be temporarily detected or not
detected at all. Obstacles located above or
below the sensors will not be detected
when they are in close proximity.
The vehicle must be driven slowly when
using ParkSense in order to be able to stop
in time when an obstacle is detected. It is
recommended that the driver looks over
his/her shoulder when using ParkSense.

Drivers must be careful when performing
parallel or perpendicular parking maneu-
vers even when using the ParkSense Active
Park Assist system. Always check carefully
behind and in front of your vehicle, look
behind and in front of you, and be sure to
check for pedestrians, animals, other vehi -
cles, obstructions, and blind spots before
backing up and moving forward. You are
responsible for safety and must continue to
pay attention to your surroundings. Failure
to do so can result in serious injury or
death.

Do not jerk the steering wheel in response
to a warning.
Never attempt to swerve around animals if
doing so would endanger you or other
drivers on the road.
Do not stare at the image while driving. You
could crash and you or others could be
injured.
The Night Vision system only provides alerts
to objects of interest and cannot serve as a
substitute for the driver’s personal judg-
ment. The warnings are meant to direct
your attention to the detected objects, but
the Night Vision system does not automati -
cally brake the vehicle and may not provide
a warning with enough time to help avoid a
crash.
Warnings are only provided if a pedestrian
or large animal is detected by the system.

Night Vision can only detect pedestrians
and animals located within the range of the
infrared camera.
Night Vision may not detect pedestrians or
animals and highlight them if:
They are not in an upright position, for
example if they are sitting or lying down,
or if the pedestrian is riding a bicycle
The figure in the display appears incom-
plete, for example because the pedes -
trian or animal is partially behind a
vehicle
The pedestrian/animal is not directly
ahead in the coverage area

Do not tow a trailer at all during the first
500 miles (805 kmyfWKHQHZYHKLFOHLV driven. The engine, axle or other parts could
be damaged.
Then, during the first 500 miles (805 kmyf that a trailer is towed, do not drive over
50 mph (80 km/hyfDQGGRQRWPDNHVWDUWV
at full throttle. This helps the engine and
other parts of the vehicle wear in at the
heavier loads.
WARNING!
Make certain that the load is secured in the
trailer and will not shift during travel. When
trailering 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 colli -
sion.
When hauling cargo or towing a trailer, do
not overload your vehicle or trailer. Over -
loading can cause a loss of control, poor
performance or damage to brakes, axle,
engine, transmission, steering, suspension,
chassis structure or tires.
Safety chains must always be used
between your vehicle and trailer. Always
connect the chains to the hook retainers of
the vehicle hitch. Cross the chains under
the trailer tongue and allow enough slack
for turning corners.

UCONNECT SYSTEMS
For detailed information about your Uconnect
5/5 NAV With 8.4-inch Display or Uconnect

your Uconnect Owner’s Manual Supplement.
NOTE:

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 softwareyfLVLQVWDOOHG.
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 or CDyfLQWR
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 the
nearest authorized dealer immediately.

The ABS contains sophisticated electronic
equipment that may be susceptible to inter-
ference caused by improperly installed or
high output radio transmitting equipment.
This interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment should be performed by
qualified professionals.

Electronic Stability Control (ESCyfFDQQRW
prevent the natural laws of physics from
acting on the vehicle, nor can it increase
the traction afforded by prevailing road
conditions. ESC cannot prevent accidents,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent accidents resulting from loss of
vehicle control due to inappropriate driver
input for the conditions. Only a safe, atten-
tive, and skillful driver can prevent acci -
dents. The capabilities of an ESC equipped
vehicle must never be exploited in a reck -
less or dangerous manner which could
jeopardize the user’s safety or the safety of
others.
