Limitations for camera and radar
unit
The camera and radar unit has certain limitations
– which in turn also limit those functions that use
the unit. A driver should be aware about the fol-
lowing examples of limitations.
Camera and radar
Blocked unit
The marked area must be cleaned regularly and kept
free from stickers, objects, shade film, etc.
Cause
The windscreen surface in front of the camera and radar unit is dirty or
covered with ice or snow.
Thick fog and heavy rain or snow block the radar signals or the camera
view.
The camera unit is placed inside the upper sec-
tion of the windscreen together with the car's
radar unit.
Do not place, stick or mount anything on the
inside or outside of the windscreen, in front of or
around the camera and radar unit – this may
interfere with camera and radar-based functions.
This may result functions being reduced, being
switched off completely or giving incorrect func-
tion responses.
If the driver display shows this symbol
and the message " Windscreen
sensor Sensor blocked, see
Owner's manual
", this means that the
camera and radar unit cannot detect other vehi-
cles, cyclists, pedestrians and large animals in
front of the car, and that the car's camera-based
and radar-based functions may be disrupted,
reduced, completely deactivated or give an incor-
rect function response.
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.
