.
The radar unit is placed inside the upper section
of the windscreen together with the car's camera
unit.
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.
This may mean that functions are reduced,
deactivated completely or give incorrect func-
tion response.
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 possible causes for a message being shown, along with the appropriate action:
Cause Action

ered with ice or snow.
Clean dirt, ice and snow from the windscreen surface in front of the camera
and radar unit.
