Cause Action
Water or snow is spraying/swirling up and blocking the radar signals or
the 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/radar
sensor.
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 camera
and radar unit clean.
Vehicle speed
The radar sensor's ability to detect a vehicle
ahead is significantly reduced if:
•
the speed of the vehicle ahead differs greatly
from your vehicle's speed
Limited field of vision
The radar sensor has a limited field of vision. In
some situations, it may detect a vehicle later than
expected or not at all.
The radar sensor's field of vision.
The radar sensor's detection of vehicles very
close to your vehicle may be delayed in cer-
tain situations, e.g. if a vehicle pulls in
between your vehicle and the vehicle directly
ahead.
Small vehicles, such as motorcycles, or vehi-
cles that are not driving in the center of the
lane may remain undetected.
In curves, the radar may detect the wrong
vehicle 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 be
extra alert when driving behind vehicles towing
low trailers when Adaptive Cruise Control or Pilot
Assist is activated.
