“Clean Front Windshield” Warning
The “ACC/FCW Limited Functionality Clean Front Wind-
shield” warning will display and also a chime will indicate
when con
ditions 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 display “ACC/
FCW Limited Functionality Clean Front Windshield” and
the system will have degraded performance.
The “ACC/FCW Limited Functionality Clean Front Wind-
shield” message can sometimes be displayed while driving
in adve
rse 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 rear view mirror. They may require
cleaning or removal of an obstruction.
When the condition that created limited functionality is no
longer p
resent, the system will return to full functionality.
NOTE:
If the “ACC/FCW Limited Functionality Clean Front Wind-
shield” message occurs frequently (e.g. more than once on
e
very tr
ip) without any snow, rain, mud, or other obstruc-
tion, have the windshield and forward facing camera
i
nspect
ed at your authorized dealer.
Service ACC/FCW Warning
If the system turns off, and the instrument cluster 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 unavail
-
able. If this occurs, try activating ACC again later, following
a
n ignit
ion cycle. If the problem persists, see your authorized
dealer.
