“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 Sensor 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.

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 malfunction or failure and require a sensor realignment.

• 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.

• If the “Clean Radar Sensor In Front Of Vehicle” message occurs frequently (e.g. more than once on every trip) without any snow, rain, mud, or other obstruction, have the radar sensor realigned at your authorized dealer.

• Installing a snow plow, front-end protector, an aftermarket grille or modifying the grille is not recommended.

Doing so may block the sensor and inhibit ACC operation.
