WARNING!
When the ACC system is resumed, the driver
must ensure that there are no pedestrians,
vehicles or objects in the path of the vehicle.
Failure to follow these warnings can result in
a collision and death or serious personal
injury.
Display Warnings And Maintenance
"Wipe Front Radar Sensor In Front Of Vehicle"
Warning
The "ACC/FCW Unavailable Wipe Front Radar
Sensor" 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. The ACC system
may also become temporarily blinded due to
obstructions, such as mud, dirt or ice. In these
cases, the instrument cluster display will display
the above message and the system will
deactivate.
This message can sometimes be displayed
while driving in highly reflective areas (i.e. ice
and snow, or tunnels with reflective tiles). The
ACC system will recover after the 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, Fixed Speed Cruise
Control is still available.
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
important 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.
STARTING AND OPERATING
If the sensor or front end of the vehicle is

damaged due to a collision, see an 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.
