Radar Sensor Limitations - Volvo V90 Owner's Manual

Radar sensor limitations

The radar sensor used by several of the driver
support functions has certain limitations, which
also affect the functions using the radar sensor.
Obstructed camera
The area marked in the illustration must be kept free of
69
decals, objects, solar film, etc.
The following table shows some of the situations that can cause the message to be displayed, and suggested actions:
Cause
The area of the windshield in front of the camera/radar sensor is dirty or
covered by ice or snow.
Thick fog, heavy rain or snow is blocking the radar signals or the camera's
range of visibility.
69 Note: This illustration is general and details may vary depending on model.
The radar sensor is located on the upper interior
section of the windshield along with the camera.
CAUTION
Do not place, affix or mount anything on the
inside or outside of the windshield, or in front
of or around the camera and radar unit – this
could disrupt camera and radar-based func-
tions.
It could cause functions to be reduced, deac-
tivated completely or produce an incorrect
function response.
Action
Clean the windshield in front of the camera/radar sensor and remove dirt, ice
and snow.
No action. Heavy precipitation may sometimes prevent the camera/radar sensor
from functioning.
DRIVER SUPPORT
If this symbol and the message
" Windscreen sensor Sensor
blocked, see Owner's manual
displayed in the instrument panel, it
means that the camera and radar sensor are
unable to detect other vehicles, cyclists, pedes-
trians and large animals in front of the vehicle
and that the vehicle's camera and radar-based
functions may be obstructed, reduced, completely
disabled or providing inaccurate responses.
