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.
Water or snow is spraying/swirling up and blocking the radar signals
or the camera's range of visibility.
There is dirt between the inside of the windshield and the camera/
radar sensor.
Bright sunlight
NOTE
Keep the windshield in front of the camera
and radar unit clean.
High temperatures
If the temperature in the passenger compartment
is very high, the camera/radar sensor will switch
off temporarily for approx. 15 minutes after the
engine is started to protect its electronic compo-
nents. When the temperature has cooled suffi-
ciently, the camera/radar sensor will automati-
cally restart.
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.
No action. Very wet or snow-covered roads may sometimes prevent the camera/
radar sensor from functioning.
Consult a workshop to have the area of the windshield on the inside of the camera's
casing cleaned. An authorized Volvo workshop is recommended.
No action. The camera/radar sensor will reset automatically when lighting conditions
improve.
Damaged windshield
CAUTION
If there are cracks, scratches or stone chips
on the windshield in front of any of the cam-
era and radar unit "windows" and this covers
an area of about 0.5 × 3.0 mm
(0.02 × 0.12 in.) or more, contact a workshop
to have the windshield replaced – an author-
ized Volvo workshop is recommended.
Failure to take action could result in reduced
performance for the driver support systems
that use the camera and radar unit.
DRIVER SUPPORT
It could cause functions to be reduced, deac-
tivated completely or produce an incorrect
function response.
To avoid the risk of loss of function, malfunc-
tion or reduced function of the driver support
systems that use the radar unit, the following
also apply:
•
Volvo advises against repairing cracks,
scratches or stone chips in the area in
front of the camera and radar unit – the
entire windshield should instead be
replaced.
•
Before replacing the windshield, contact
an authorized Volvo workshop to verify
