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 EVIC 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
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 205
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 informa-
tion 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 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.
