Display Warnings And Maintenance

"Clean Radar Sensor In Front Of Vehicle"
Warning
The ACC "Clean Radar Sensor In Front Of
Vehicle" warning will display 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 "Clean Radar Sen-
sor In Front Of Vehicle" and the system will
deactivate.
The "Clean Radar Sensor In Front Of Vehicle"
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.
Clean Radar Sensor Warning
NOTE:
If the ACC "Clean Radar Sensor In Front Of
Vehicle" 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. Be
cautious not to damage the sensor lens.
• Do not remove any screws from the sensor.
Doing so could cause an ACC system mal-
function or failure and require a sensor re-
alignment.
• If the sensor is damaged due to a collision,
see your authorized dealer for service.
• 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 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.
