Cause Action
The windscreen surface in front of the camera and radar unit is dirty or
covered with ice or snow.
Clean dirt, ice and snow from the windscreen surface in front of the camera and
radar unit.
Thick fog and heavy rain or snow block the radar signals or the camera
view.
No action. Sometimes the unit does not work during heavy rain or snowfall.
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 cam-
era and radar unit.
Visit a workshop to have the windscreen inside the unit's cover cleaned - an
authorised Volvo workshop is recommended.
Strong oncoming light No action. The camera unit is reset automatically in more favourable light condi-
tions.
NOTE
Keep the windscreen clean in front of the
camera and radar unit.
High temperature
At very high temperatures the camera and radar
unit can temporarily be switched off for
about 15 minutes after the engine is started so
as to protect the unit's electronics. The camera
and radar unit restarts automatically when the
temperature has fallen sufficiently.
Damaged windscreen
IMPORTANT
If a crack, scratch or stone chip in the wind-
screen in front of one of the camera and
radar unit “windows” covers an area of
approx. 0.5 × 3.0 mm (0.02 × 0.12 in.) or
larger, a workshop must be contacted to have
the windscreen replaced – an authorised
Volvo workshop is recommended.
If not rectified it can lead to reduced perform-
ance for the driver support systems that use
the camera and radar unit.
This may mean that functions are reduced,
deactivated completely or give incorrect func-
tion response.
To avoid the risk of failed, deficient or
reduced operation of driver support systems
that use the radar unit, the following also
applies:
•
Volvo recommends against repairing
cracks, scratches or stone chips in the
area in front of the camera and radar unit.
Instead, the whole windscreen should be
replaced.
•
Before replacing a windscreen, contact
an authorised Volvo workshop to verify
