System Limitations - Mercedes-Benz E-Class Operator's Manual

On very rare occasions, Adaptive Highbeam
Assist may fail to recognize other road users
with their own lighting, or may recognize
them too late.
In these or similar situations, the automatic
high beam is not deactivated or is activated
despite the presence of other road users.
Always observe the traffic carefully and
#
switch off the high beam in good time.
Adaptive Highbeam Assist switches automati‐
cally between:
Low beam
