Limitations of the camera unit

The camera unit has certain limitations - which in
turn also limits those functions that use the unit.
Impaired vision
The camera has limitations similar to the human
eye, i.e. it can "see" worse in for example intense
snowfall or rain, dense fog, heavy dust storms
and snow flurries. Under such conditions, the
functions of camera-dependent systems could be
significantly reduced or temporarily disengaged.
Strong oncoming light, reflections in the carriage-
way, snow or ice on the road surface, dirty road
surfaces or unclear lane markings can also sig-
nificantly reduce camera function when it is used
to scan the carriageway to detect pedestrians,
cyclists and other vehicles.
Cause
The windscreen surface in front of the camera and radar unit is dirty or cov-
ered with ice or snow.
Thick fog and heavy rain or snow block the radar signals or the camera
view.
Water or snow from the road surface swirls up and blocks the radar signals
or camera view.
Dirt has appeared between the inside of the windscreen and the camera
and radar unit.
294
Blocked unit
The marked area must be kept free from stickers,
objects etc.
The camera unit is placed inside the upper sec-
tion of the windscreen together with the car's
radar unit.
Action
Clean dirt, ice and snow from the windscreen surface in front of the camera
and radar unit.
No action. Sometimes the unit does not work during heavy rain or snowfall.
No action. Sometimes the unit does not work on a very wet or snow-covered
road surface.
Visit a workshop to have the windscreen inside the unit's cover cleaned - an
authorised Volvo workshop is recommended.
IMPORTANT
Do not place, stick or mount anything on the
outside or inside of the windscreen in front of
or around the camera and radar unit — this
can interfere with camera and radar-depend-
ent functions.
If the driver display shows this symbol
with the message Windscreen
sensor Sensor blocked, see
Owner's manual
, it means that the
camera and radar unit cannot detect other vehi-
cles in front of the car.
The following table presents examples of possi-
ble causes for a message being shown, along
