STARTING AND OPERATING
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 condi-
tions 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 clus-
ter display will display "ACC/FCW Unavailable Wipe
Front Radar Sensor" and the system will deactivate.
The "ACC/FCW Unavailable Wipe Front Radar Sensor"
message can sometimes be displayed while driving in
highly reflective areas (i.e. tunnels with reflective tiles,
or ice and snow). 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 impor-
tant 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.
•
If the sensor or front end of the vehicle is damaged
due to a collision, see an authorized dealer for
service.
•
Do not attach or install any accessories near the
sensor, including transparent material or aftermar-
ket grilles. Doing so could cause an ACC system fail-
ure 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
authorized dealer.
"CLEAN FRONT WINDSHIELD" WARNING
The "ACC/FCW Limited Functionality Clean Front Wind-
shield" 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 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 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 rear view 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 Wind-
shield" 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.
