DRIVER SUPPORT
Camera/radar sensor limitations
The camera and radar sensor used by several of
the driver support functions has certain limita-
tions, which also affect the functions using the
camera and radar sensor. The driver should be
aware of the following limitations:
Camera and radar
Obstructed camera
The area marked in the illustration must be cleaned reg-
ularly and kept free of decals, objects, solar film, etc.
Cause
The area of the windshield in front of the camera/radar sensor is
dirty or covered by ice or snow.
Thick fog, heavy rain or snow is blocking the radar signals or the
camera's range of visibility.
316
The camera is located on the upper interior sec-
tion of the windshield along with the radar sen-
sor.
Do not place, affix or mount anything on the
inside or outside of the windshield, or in front of
or around the camera and radar sensor – this
could disrupt camera and radar-based functions.
It could cause functions to be reduced, deacti-
vated completely or to produce an incorrect func-
tion response.
If this symbol and the message
Windscreen sensor Sensor
"
blocked, see Owner's manual
displayed in the instrument panel, it
means that the camera and radar sensor are
unable to detect other vehicles, cyclists, pedes-
trians and large animals in front of the vehicle
and that the vehicle's camera and radar-based
functions may be obstructed, reduced, completely
disabled or providing inaccurate responses.
Action
Clean the windshield in front of the camera/radar sensor and remove dirt, ice and
snow.
No action. Heavy precipitation may sometimes prevent the camera/radar sensor from
functioning.
The following table shows some of the situations
that can cause the message to be displayed, and
suggested actions:
