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 cam-
era/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.
Bright sunlight.
No action. The camera/radar sensor will reset automatically when lighting con-
ditions improve.
To avoid the risk of malfunction of the driver
support systems that use the radar sensor, the
following also apply:
The same type of windshield wipers or
wipers approved by Volvo should be used
for replacement.
High temperatures
•
•
If the temperature in the passenger compart-
ment is very high, the camera/radar sensor
will switch off temporarily for
approx. 15 minutes after the engine is started
to protect its electronic components. When
the temperature has cooled sufficiently, the
camera/radar sensor will automatically restart.
If the windshield is replaced, the camera
and radar sensor must be recalibrated by a
workshop53 to help ensure proper func-
tioning of all of the vehicle's camera and
radar-based systems.
If there are cracks, scratches or stone
chips on the windshield in front of any of
the camera and radar sensor "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

.
Vehicle speed
NOTE
Volvo advises against repairing cracks,
scratches or stone chips in the area in
front of the camera and radar sensor – the
entire windshield should instead be
replaced.
•
•
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.
Failure to take action could result in
reduced performance for the driver support
systems that use the camera and radar
unit. It could cause functions to be
reduced, deactivated completely or to pro-
duce an incorrect function response.
Before replacing the windshield, contact a
workshop53 to verify that the right wind-
shield has been ordered and installed.
