Cause Action
Water or snow from the road surface swirls up and blocks the radar signals
or camera view.
No action. Sometimes the unit does not work on a very wet or snow-covered
road surface.
Dirt has appeared between the inside of the windscreen and the camera
and radar unit.
Visit a workshop to have the windscreen inside the unit's cover cleaned - an
authorised Volvo workshop is recommended.
NOTE
Keep the windscreen clean in front of the
camera and radar unit.
Vehicle speed
The capacity of the radar unit to detect vehicles
ahead is reduced significantly if:
•
the speed of the vehicle ahead is signifi-
cantly different from that of your own car
Limited field of vision
The radar unit has a limited field of vision. In
some situations another vehicle is not detected,
or the detection is made later than expected.
The radar unit's field of vision.
Sometimes the radar unit is late at detecting
vehicles at close distances - e.g. a vehicle
that drives in between your car and the vehi-
cle ahead.
Small vehicles, such as motorcycles, or vehi-
cles not driving in the centre of the lane can
remain undetected.
In bends, the radar unit may detect the
wrong vehicle or lose a detected vehicle from
view.
Low trailers
Low trailer in radar shadow.
Low trailers can also be difficult for the radar unit
to detect, or are not detected at all - the driver
should therefore be particularly careful when driv-
ing behind low trailers when the adaptive cruise
control or Pilot Assist is activated.
