STARTING AND OPERATING 153
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 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 authorized
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 operation.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC Limited Functionality Clean Front
Windshield” warning will display, and a chime
will sound 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 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 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 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 wind-
shield and forward facing camera inspected at
an authorized dealer.
SERVICE ACC WARNING
If the system turns off, and the instrument
cluster display reads “ACC Unavailable Service
Required” or “Cruise 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.
