STARTING AND OPERATING
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 “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. 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 camera in the
center of the windshield, on the forward side of the
rearview mirror.
To keep the ACC system operating properly, it is important
to note the following maintenance items:
Always keep the sensor clean. Carefully clear the wind
-
shield.
Do not remove any screws from the sensor. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
Do not attach or install any accessories near the
sensor, including transparent material. 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
authorized dealer.
Installing a snowplow, front-end protector, an after
-
market grille or modifying the grille is not recom
-
mended. Doing so may block the sensor and inhibit
ACC/FCW operation.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/FCW 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,
driving directly into the sun and fog on the inside of glass.
In these cases, the instrument cluster display will show
“ACC/FCW 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/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 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/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.
