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/FCW Unavailable Wipe Front Radar
Sensor” 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 or front end of the vehicle 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.
206 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

When the condition that created limited functionality is no
longer present, the system will return to full functionality.
NOTE:If the “ACC/FCW Limited Functionality Clean
Front Windshield” message occurs frequently (e.g. more
than once on every trip) without any snow, rain, mud, or
other obstruction, have the windshield and forward
facing camera inspected at your authorized dealer.
Service ACC/FCW Warning
If the system turns off, and the EVIC displays “ACC/
FCW Unavailable Service Required”or “Cruise/FCW
Unavailable Service Required”, there may be an internal
system fault or 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.
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.
Towing A Trailer
NOTE: Towing a trailer is not advised when using ACC.
Offset Driving
ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel, or a vehicle merging
in from a side lane. There may 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.
208 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Although the vehicle is still drivable under normal
conditions, the active braking may not be fully available.
Once the condition that limited the system performance
is no longer present, the system will return to its full
performance state. If the problem persists, see your
authorized dealer.
Service FCW Warning
If the system turns off, and the EVIC displays:
•ACC/FCW Unavailable Service Required
• Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault. Although
the vehicle is still drivable under normal conditions, have
the system checked by an authorized dealer.
LANESENSE — IF EQUIPPED
LaneSense Operation
The LaneSense system is operational at speeds above
37 mph (60 km/h) and below 112 mph (180 km/h). The
LaneSense system uses a forward looking camera to
detect lane markings and measure vehicle position
within the lane boundaries.
When both lane markings are detected and the driver
unintentionally drifts out of the lane (no turn signal
applied), the LaneSense system provides a haptic warn-
ing in the form of torque applied to the steering wheel to
prompt the driver to remain within the lane boundaries.
If the driver continues to unintentionally drift out of the
lane, the LaneSense system provides a visual warning
through the instrument cluster to prompt the driver to
remain within the lane boundaries.

Enabling And Disabling ParkSense®
ParkSense® can be enabled and disabled with the
ParkSense® switch, located on the switch panel below
the Uconnect® display.When the ParkSense® switch is pressed to disable the
system, the instrument cluster will display the
“PARKSENSE OFF” message for approximately five sec-
onds. Refer to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument Panel” for
further information. When the shift lever is moved to
REVERSE and the system is disabled, the EVIC will
display the “PARKSENSE OFF” message for as long as
the vehicle is in REVERSE.
The ParkSense® switch LED will be ON when
ParkSense® is disabled or requires service. The

Service The ParkSense® Rear Park Assist
System
During vehicle start up, when the ParkSense® Rear Park
Assist System has detected a faulted condition, the instru-
ment cluster will actuate a single chime, once per ignition
cycle, and it will display the “PARKSENSE UNAVAIL-
ABLE WIPE REAR SENSORS” or the “PARKSENSE UN-
AVAILABLE SERVICE REQUIRED” message. Refer to
“Electronic Vehicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further information.
When the shift lever/gear selector is moved to REVERSE
and the system has detected a faulted condition, the EVIC
will display thePARKSENSE UNAVAILABLE WIPE
REAR SENSORS orPARKSENSE 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) 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, 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/gear selector to the
REVERSE position and ParkSense® is turned OFF, the
EVIC 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.
