334 STARTING AND OPERATING
NOTE:
• If the “ACC/FCW Unavailable Wipe Front Radar Sensor”
mes
sage occurs frequently (e.g. more than once on every
trip) without any snow, rain, mud, or other obstruction,
have the radar sensor realigned at your authorized dealer.
• Installing a snow plow, front-end protector, an after-
mar
ket grille or modifying the grille is not recommended.
Doin
g so may block the sensor and inhibit ACC/FCW
operation.
“Clean Front Windshield” Warning
The “ACC/FCW Limited Functionality Clean Front Wind-
shield” 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 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 a
dverse 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
exam
ine 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
longe
r present, 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
ever
y trip) without any snow, rain, mud, or other obstruc-
tion, have the windshield and forward facing camera
insp
ected 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 unavailable. If this occurs, try acti
-
vating ACC again later, following an ignition cycle. If the
prob
lem persists, see your authorized dealer.
