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 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. 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. 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 Normal (Fixed Speed) Cruise Control is
still available. For additional information refer to “Normal
(Fixed Speed) Cruise Control Mode” in this section.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 or aftermarket grilles.
Doing so could cause an ACC system failure or malfunc -
tion.
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 reac -
tivating it.
