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.
