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.
Precautions While Driving With ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpect-
edly. The driver needs to stay alert and may need to
intervene.
Adding A Trailer Hitch
The weight of a trailer/hitch may affect the performance
of ACC. If there is a noticeable change in performance
following the installation of a trailer/hitch, or if the ACC
performance does not return to normal after removing
the trailer/hitch see your authorized dealer.
Offset Driving
ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel. There will not be
sufficient distance to the vehicle ahead. The offset vehicle
may move in and out of the line of travel, which can
cause your vehicle to brake or accelerate unexpectedly.

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.

Service FCW 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.
PARKSENSEPARK 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.
Refer to ParkSense System Usage Precautions for limi-
tations of this system and recommendations. ParkSense
will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSense can be active only when the shift lever is in
REVERSE or DRIVE. If ParkSense is 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 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.
The six ParkSense sensors, 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.

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 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 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 ParkSense off, the EVIC will display
“PARK ASSIST SYSTEM 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 or
DRIVE position and ParkSense is 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.
238 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 ParkSense system 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!
•ParkSense is 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
ParkSense in 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.
