indicated in page 354, Cleaning the ex-
terior. When the radar sensor starts cor-
rectly detecting again, the message disap-
pears from the screen and the functions
become available again.
CAUTION
If the radar sensor is dirty or poorly ad-
●
justed, 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 correct-
●
ly if it receives an impact. This may com-
promise the system's efficacy or discon-
nect it. If you have the feeling that the ra-
dar sensor is damaged or adjusted incor-
rectly, switch off the Front Assist and ACC
functions to avoid any damage. If this oc-
curs have it adjusted.
