Radar sensor limitations
The radar sensor used by several of the driver
support systems has certain limitations, which
also affect the systems using it.
Obstructions
The marked area must not be obstructed in any way.
This area of the windshield should always be kept clean
The radar sensor is located at the upper, center
section of the windshield along with the camera.
WARNING
Never place any objects, decals, etc., on the
windshield in front of the camera/radar unit.
This could reduce or block these components'
functions, and could cause one or more of the
systems that utilize the them to stop function-
ing.
If this symbol and the message
Windscreen Sensors blocked
appear in the instrument panel, this
indicates that the camera and/or radar
sensor cannot detect other vehicles ahead.
The following table shows some of the situations
that can cause the message to be displayed and
suggested actions.
Cause Action
The area of the windshield in front of the camera/radar sensor is dirty or covered by ice or
snow. Clean the windshield or remove the ice/ snow.
Thick fog or heavy rain/snow blocks reduces the camera/radar sensor's range of visibility. No action. The driver should be extra alert in conditions of this
type.
Water or snow on the surface of the road swirl up and block radar signals or the camera's
view. No action. The driver should be extra alert in conditions of this
type.
There is dirt between the inside of the windshield and the camera/radar sensor. Have the area of the windshield cleaned by a trained and quali-
fied Volvo service technician.
