Display Warnings And Maintenance

"Front Radar Sensor Temporarily Blocked" Warning
The "ACC Front Radar Sensor Temporarily Blocked" warn-
ing 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
read "ACC/FCW Unavailable Wipe Front Radar Sensor"
and the system will deactivate.
The "ACC Front Radar Sensor Temporarily Blocked" mes-
sage 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 Front Radar Sensor Temporarily
Blocked" 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 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. Do not use solvents or abrasive
substances.
