FORWARD COLLISION WARNING (FCW) WITH
MITIGATION — IF EQUIPPED
Forward Collision Warning (FCW) With Mitigation
Operation
The Forward Collision Warning (FCW) system with
mitigation provides the driver with audible warnings,
visual warnings (within the EVIC/DID), and may apply
a brake jerk to warn the driver when it detects a potential
frontal collision. The warnings and limited braking are
intended to provide the driver with enough time to react,
avoid or mitigate the potential collision.
NOTE:FCW monitors the information from the forward
looking sensors as well as the Electronic Brake Controller
(EBC), to calculate the probability of a forward collision.
When the system determines that a forward collision is
probable, the driver will be provided with audible and
visual warnings and may provide a brake jerk warning.
If the driver does not take action based upon these
progressive warnings, then the system will provide a
limited level of active braking to help slow the vehicle
and mitigate the potential forward collision. If the driver
reacts to the warnings by braking and the system deter-
mines that the driver intends to avoid the collision by

(EVIC) or Driver Information Display (DID) indicating
the vehicle speed is too fast. The system will become
active again if the vehicle speed is decreased to speeds
less than approximately 6 mph (9 km/h).
ParkSense® Sensors
The four ParkSense® sensors, 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.
ParkSense® Warning Display
The ParkSense® Warning screen will only be displayed if
Sound and Display is selected from the Customer -
Programmable Features section of the Uconnect® Sys-
tem. Refer to#Uconnect® Settings” in “Understanding
Your Instrument Panel” for further information.
The ParkSense® Warning screen is located within the
EVIC/DID. It provides visual warnings to indicate the
distance between the rear fascia/bumper and the de-
tected obstacle. Refer to “Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID)” for
further information.
ParkSense® Display
When the vehicle is in REVERSE, the EVIC/DID will
display the park assist ready system status.
The system will indicate a detected obstacle by showing
a single arc in one or more regions based on the obstacle’s
distance and location relative to the vehicle.
If an obstacle is detected in the center rear region, the
display will show a single solid arc in the center rear
region and will produce a one-half second tone. As the
vehicle moves closer to the obstacle, the display will
show the single arc moving closer to the vehicle and the
sound tone will change from slow, to fast, to continuous.

Service The ParkSense® Rear Park Assist
System
During vehicle start up, when the ParkSense® Rear Park
Assist System has detected a faulted condition, the
instrument cluster will actuate a single chime, once per
ignition cycle, and it will display the “PARKSENSE
UNAVAILABLE WIPE REAR SENSORS” or the
“PARKSENSE UNAVAILABLE SERVICE REQUIRED”
message. Refer to “Electronic Vehicle Information Center
(EVIC) or Driver Information Display (DID)” for further
information. When the shift lever/gear selector is moved
to REVERSE and the system has detected a faulted
condition, the EVIC/DID will display the#PARKSENSE
UNAVAILABLE WIPE REAR SENSORS#or
#PARKSENSE UNAVAILABLE SERVICE REQUIRED#
message for as long as the vehicle is in REVERSE. Under
this condition, ParkSense® will not operate.
If “PARKSENSE UNAVAILABLE WIPE REAR SEN-
SORS” appears in the Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID) make
sure the outer surface and the underside of the rear
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 “PARKSENSE UNAVAILABLE SERVICE REQUIRED”
appears in the EVIC/DID, see an authorized dealer.
Cleaning The ParkSense® System
Clean the ParkSense® sensors 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.
ParkSense® System Usage Precautions
NOTE:
•Ensure that the rear bumper is free of snow, ice, mud,
dirt and debris to keep the ParkSense® system oper-
ating properly.

•Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense®.
•When you turn ParkSense® OFF, the instrument clus-
ter will display “PARKSENSE OFF” Furthermore, once
you turn ParkSense® off, 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
position and ParkSense® is turned OFF, the EVIC/
DID will display “PARKSENSE OFF” message for as
long as the vehicle is in REVERSE.
•ParkSense®, when on, will reduce the volume of the
radio when it is sounding a tone.
•Clean the ParkSense® sensors 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 ParkSense® system might not detect an
obstacle behind the fascia/bumper, or it could provide
a false indication that an obstacle is behind the fascia/
bumper.
•Use the ParkSense® switch to turn the ParkSense®
system OFF if objects such as bicycle carriers, trailer
hitches, etc. are placed within 12 in (30 cm) from the
rear fascia/bumper. Failure to do so can result in the
system misinterpreting a close object as a sensor
problem, causing the “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message to be displayed in the
EVIC/DID.
•ParkSense® should be disabled when the liftgate is in
the open position and the vehicle is in REVERSE. An
open liftgate could provide a false indication that an
obstacle is behind the vehicle.
242 UNDERSTANDING THE FEATURES OF YOUR 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®.
WARNING!
•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.

WARNING!(Continued)
•Before using ParkSense®, it is strongly recom-
mended that the ball mount and hitch ball assem-
bly is 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 loudspeaker
sounds the continuous tone. Also, the sensors
could detect the ball mount and hitch ball assem-
bly, depending on its size and shape, giving a false
indication that an obstacle is behind the vehicle.
PARKSENSE® FRONT AND REAR PARK ASSIST
— IF EQUIPPED
The ParkSense® Park 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.
If your vehicle is equipped with an Automatic Transmis-
sion, the vehicle brakes may be automatically applied
and released when performing a reverse parking maneu-
ver if the system detects a possible collision with an
obstacle.
NOTE:
•The driver can override the automatic braking func-
tion by pressing the gas pedal, turning ParkSense® off
via ParkSense® switch, or changing the gear while the
automatic brakes are being applied.
•Automatic brakes will not be available if ESC is not
available.
•Automatic brakes will not be available if there is a
faulted condition detected with the ParkSense® Park
Assist system or the Braking System Module.
