page 351, Cleaning the exte-
rior. When the radar sensor starts correctly
detecting again, the message disappears
from the screen and the functions become
available again.
CAUTION
●
If the radar sensor is dirty or poorly adjus-
ted, the Front Assist system may give un-
necessary warnings and apply the brakes
inappropriately.
●
The operation of the radar can be affec-
ted by strong reflections of the emitted sig-
nal. This may occur, for example, in an en-
closed car park or due to the presence of
metallic objects (e.g. guard rails or sheets
used in road works).
●
The sensor may not be adjusted correctly
if it receives an impact. This may compro-
mise the system's efficacy or disconnect it.
If you have the feeling that the radar sensor
is damaged or adjusted incorrectly, switch
off the Front Assist and ACC functions to
avoid any damage. If this occurs have it ad-
justed.
