The “Clean Radar Sensor In Front Of Vehicle” message
can sometimes be displayed while driving in highly
reflective areas (i.e. tunnels with reflective tiles, or ice and
snow). The ACC system will recover after the vehicle has
left these areas. Under rare conditions, when the radar is
not tracking any vehicles or objects in its path this
warning may temporarily occur.
NOTE:If the ACC “Clean Radar Sensor In Front Of
Vehicle” warning is active Normal (Fixed Speed) Cruise
Control is still available. For additional information refer
to “Normal (Fixed Speed) Cruise Control Mode” in this
section.
If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located in the center of the
vehicle behind the lower grille.To keep the ACC System operating properly, it is impor-
tant to note the following maintenance items:
•Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to
damage the sensor lens.
•Do not remove any screws from the sensor. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
•If the sensor is damaged due to a collision, see your
authorized dealer for service.
•Do not attach or install any accessories near the sensor,
including transparent material or aftermarket grilles.
Doing so could cause an ACC system failure or
malfunction.

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.
Adaptive Cruise Control (ACC) Unavailable Warning

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 215

ACC may occasionally provide braking and/or a driver
alert that you consider unnecessary. This may be the
system’s response to signs, guardrails, and other station-
ary objects in a curve. This may also occur at the base of
steep hills. This is normal operation and your vehicle
does not require service.
Using ACC On Hills
When driving on hills, ACC may not detect a vehicle in
your lane. Depending on the speed, vehicle load, traffic
conditions, and the steepness of the hills, ACC perfor-
mance may be limited.

FCW Unavailable Warning
If the system turns off, and the EVIC displays “ACC/
FCW Unavailable, Vehicle System Error”, there may be a
temporary malfunction that limits FCW functionality.
Although the vehicle is still drivable under normal
conditions, FCW will be temporarily unavailable. If this
occurs, try activating FCW again later, following a key
cycle. If the problem persists, see your authorized dealer.
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.

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.
