CauseAction
Water or snow is spraying/swirling up and blocking the radar signals orthe camera's range of visibility.No action. Very wet or snow-covered roads may sometimes prevent the cam-era/radar sensor from functioning.
There is dirt between the inside of the windshield and the camera/radarsensor.Consult a workshop to have the area of the windshield on the inside of the cam-era's casing cleaned. An authorized Volvo workshop is recommended.

NOTE
Keep the windshield in front of the cameraand radar unit clean.

Vehicle speed
The radar sensor's ability to detect a vehicleahead is significantly reduced if:
the speed of the vehicle ahead differs greatlyfrom your vehicle's speed

Limited field of vision
The radar sensor has a limited field of vision. Insome situations, it may detect a vehicle later thanexpected or not at all.
The radar sensor's field of vision.
The radar sensor's detection of vehicles veryclose to your vehicle may be delayed in cer-tain situations, e.g. if a vehicle pulls in
between your vehicle and the vehicle directlyahead.
Small vehicles, such as motorcycles, or vehi-cles that are not driving in the center of thelane may remain undetected.
In curves, the radar may detect the wrongvehicle or lose sight of a target vehicle.
Low trailers
Low trailer in the radar shadow.
Low trailers may also be difficult or even impossi-ble for the radar to detect. The driver should beextra alert when driving behind vehicles towinglow trailers when Adaptive Cruise Control or PilotAssist is activated.
