When the condition that deactivated the system is no
longer present, the system will return to the “Adaptive
Cruise Control Off” state and will resume function by
simply reactivating it.
NOTE:Installing a vehicle front-end protector or an
aftermarket grille or modifying the grille is not recom-
mended. Doing so may block the sensor and inhibit ACC
operation.
ACC Unavailable Warning
If the system turns off, and the EVIC displays “Adaptive
Cruise Control (ACC) Unavailable”, there may be a
temporary malfunction that limits ACC functionality.
Although the vehicle is still drivable under normal
conditions, ACC will be temporarily unavailable. If this
occurs, try activating ACC again later, following a key
cycle. If the problem persists, see your authorized dealer.
Service ACC Warning
If the system turns off, and the EVIC displays “ACC/
FCW Unavailable Service Radar Sensor”, it indicates
there is an internal system fault. Although the vehicle is
still drivable under normal conditions, have the system
checked by an authorized dealer.

Forward Collision Warning — If Equipped
Forward Collision Warning (FCW) warns the driver of a
potential collision with the vehicle in front of you and
prompts the driver to take action in order to avoid the
collision.
FCW monitors the information from the forward looking
sensor as well as the Electronic Brake Controller (EBC),
wheel speed sensors, i.e., to calculate a probable rear-end
collision. When the system determines that a rear-end
collision is probable a warning message (both audible
and visual) will be displayed on the EVIC. When the
system determines a collision with the vehicle in front of
you is no longer probable, the warning message will be
deactivated.
NOTE:The minimum speed for FCW activation is
10 mph (16 km/h).WARNING!
Forward Collision Warning (FCW) is not intended to
avoid a collision on its own. The driver has the
responsibility to avoid a collision by controlling the
vehicle via braking and steering. Failure to follow
this warning could lead to serious injury or death.
Changing FCW Status
The FCW feature can be set to far, set to near or turned off
using the Uconnect Touch™ System, refer to “Uconnect
Touch™ Settings” in “Understanding Your Instrument
Panel” for further information. The FCW Status Off, Near
or Far will be displayed in the Uconnect Touch™ display.

PARKSENSEPARK ASSIST — IF EQUIPPED
The ParkSensePark Assist system provides visual and
audible indications of the distance between the rear
and/or front fascia and a detected obstacle when backing
up or moving forward, e.g. during a parking maneuver.
Refer to ParkSenseSystem Usage Precautions for limi-
tations of this system and recommendations.
ParkSensewill retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSensecan be active only when the shift lever is in
REVERSE or DRIVE. If ParkSenseis enabled at one of
these shift lever positions, the system will remain active
until the vehicle speed is increased to approximately
7 mph (11 km/h) or above. The system will become
active again if the vehicle speed is decreased to speeds
less than approximately 6 mph (9 km/h).
ParkSenseSensors
The four ParkSensesensors, located in the rear fascia/
bumper, monitor the area behind the vehicle that is
within the sensors’ field of view. The sensors can detect
obstacles from approximately 12 in (30 cm) up to 79 in
(200 cm) from the rear fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.
The six ParkSensesensors, located in the front fascia/
bumper, monitor the area in front of the vehicle that is
within the sensors’ field of view. The sensors can detect
obstacles from approximately 12 in (30 cm) up to 47 in
(120 cm) from the front fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.

Front Park Assist Audible Alerts
ParkSensewill turn off the Front Park Assist audible
alert (chime) after approximately 3 seconds when an
obstacle has been detected, the vehicle is stationary, and
brake pedal is applied.
Enabling And Disabling ParkSense
ParkSensecan be enabled and disabled using the
Uconnect Touch™ System. The available choices are: Off,
Sound Only, or Sound and Display. Refer to “Uconnect
Touch™ Settings” in “Understanding Your Instrument
Panel” for further information.
When the ParkSensesoft-key is pressed to disable the
system, the EVIC will display the “PARK ASSIST SYS-
TEM OFF” message for approximately five seconds.
Refer to “Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for further
information. When the shift lever is moved to REVERSE
or to DRIVE (at or below 7 mph [11 km/h]) and thesystem is disabled, the EVIC will display the “PARK
ASSIST SYSTEM OFF” message for approximately five
seconds in REVERSE or for 5 seconds when the vehicle is
in DRIVE.
Service The ParkSensePark Assist System
When the ParkSensePark Assist System is malfunction-
ing, the instrument cluster will actuate a single chime,
once per ignition cycle. The instrument cluster will
display the “CLEAN PARK ASSIST” message when any
of the rear or front sensor(s) are blocked by snow, mud, or
ice and the vehicle is shifted into REVERSE or DRIVE.
The instrument cluster will display the “SERVICE PARK
ASSIST” message when any of the rear or front sensors
are damaged and require service. When the shift lever is
moved to REVERSE or DRIVE and the system has
detected a faulted condition, the EVIC will display the
“CLEAN PARK ASSIST”, “SERVICE PARK ASSIST” or
the “SERVICE PARK ASSIST SYSTEM” message for as
long as the vehicle is in REVERSE or DRIVE (at speeds3

less than 7 mph [11 km/h]). Under this condition
ParkSensewill not operate. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
If “CLEAN PARK ASSIST” appears in the Electronic
Vehicle Information Center (EVIC) make sure the outer
surface and the underside of the rear fascia/bumper
and/or front fascia/bumper is clean and clear of snow,
ice, mud, dirt or other obstruction and then cycle the
ignition. If the message continues to appear see an
authorized dealer.
If “SERVICE PARK ASSISTor “SERVICE PARK ASSIST
SYSTEM” appears in the EVIC, see an authorized dealer.
Cleaning The ParkSenseSystem
Clean the ParkSensesensors with water, car wash soap
and a soft cloth. Do not use rough or hard cloths. Do not
scratch or poke the sensors. Otherwise, you could dam-
age the sensors.
ParkSenseSystem Usage Precautions
NOTE:
•Ensure that the front and rear bumper are free of snow,
ice, mud, dirt and debris to keep the ParkSense
system operating properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.
•When you turn ParkSenseoff, the EVIC will display
“PARK ASSIST SYSTEM OFF.” Furthermore, once you
turn ParkSenseoff, it remains off until you turn it on
again, even if you cycle the ignition key.
•When you move the shift lever to the REVERSE or
DRIVE position and ParkSenseis turned off, the
EVIC will display “PARK ASSIST SYSTEM OFF”
message for approximately five seconds in REVERSE
or for 5 seconds when the vehicle is in DRIVE.
232 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•Clean the ParkSensesensors regularly, taking care
not to scratch or damage them. The sensors must not
be covered with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system not working
properly. The ParkSensesystem might not detect an
obstacle behind or in front of the fascia/bumper, or it
could provide a false indication that an obstacle is
behind or in front of the fascia/bumper.
•Objects such as bicycle carriers, trailer hitches, etc.,
must not be placed within 12 in (30 cm) from the rear
fascia/bumper while driving the vehicle. Failure to do
so can result in the system misinterpreting a close
object as a sensor problem, causing the “SERVICE
PARK ASSIST” message to be displayed in the EVIC.
CAUTION!
•ParkSenseis only a parking aid and it is unable
to recognize every obstacle, including small ob-
stacles. Parking curbs might be temporarily de-
tected 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
ParkSensein order to be able to stop in time
when an obstacle is detected. When backing up, it
is recommended that the driver looks over his/her
shoulder when using ParkSense.

WARNING!
•Drivers must be careful when backing up even
when using the ParkSensePark Assist System.
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.
(Continued)
WARNING! (Continued)
•Before using the ParkSensePark Assist System, it
is strongly recommended that the ball mount and
hitch ball assembly is disconnected from the ve-
hicle 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 warning display turns on the single
flashing arc and 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 indication that an obstacle is behind
the vehicle.
