138 STARTING AND OPERATING
If the sensor or front end of the vehicle is
damaged due to a collision, see your autho-
rized 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:
If the “ACC/FCW Unavailable Wipe Front
Radar Sensor” message occurs frequently
(e.g. more than once on every trip) without
any snow, rain, mud, or other obstruction,
have the radar sensor realigned at an autho-
rized dealer.
Installing a snow plow, front-end protector,
an aftermarket grille or modifying the grille is
not recommended. Doing so may block the
sensor and inhibit ACC/FCW operation.
“Clean Front Windshield” Warning
The “ACC/FCW Limited Functionality Clean Front
Windshield” warning will display, and also a
chime will indicate when conditions temporarily
limit system performance. This most often occurs
at times of poor visibility, such as in snow or
heavy rain and fog. The ACC system may also
become temporarily blinded due to obstructions,
such as mud, dirt, or ice on windshield and fog on
the inside of glass. In these cases, the instrument
cluster display will read “ACC/FCW Limited
Functionality Clean Front Windshield” and the
system will have degraded performance.
This message can sometimes be displayed
while driving in adverse weather conditions.
The ACC/FCW system will recover after the
vehicle has left these areas. Under rare
conditions, when the camera is not tracking any
vehicles or objects in its path this warning may
temporarily occur.
If weather conditions are not a factor, the driver
should examine the windshield and the camera
located on the back side of the inside rearview
mirror. They may require cleaning or removal of
an obstruction.
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 an authorized dealer.
Service ACC/FCW Warning
If the system turns off, and the instrument
cluster display reads “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 an ignition
cycle. If the problem persists, see an authorized
dealer.
