WARNING Risk of accident despite
Ad aptive Highbeam Assist
Ad aptive Highbeam Assist does not recog‐
nize thefo llowing road users:
RRo ad users without lights, e.g. pedes‐
trians
RRo ad users with poor lighting, e.g.
cyclists
RRo ad users whose lighting is obstructed,
e.g. bya bar rier
On very rare occasions, Adaptive Highbeam
Assist may failto recognize other road users
with their own lighting, or may recognize
th em too late.
In these or similar situations, the automatic
high beam is not deactivated or is activated
despite the presence of other road users.
00BBAlw ays obser vethe tra ffic carefully and
switch off the high beam in good time.

Ad aptive Highbeam Assist cannot take into
account road, weather or traf fic conditions.
De tection may be restricted if:
RVi sibility is impaired, forex ample in fog,
heavy rain or sno w.
RThere is dirt on the sensors or the sensors
are obscured.

Fu nctions of ABS (Anti-lock Brake Sy stem)
ABS regulates the brake pressure in critical driv‐
ing situations:
RDuring braking, e.g. at maximum full-s top
braking or insuf ficient traction of the tires,
th e wheels are pr evented from blocking.
RVehicle steerability while braking is ensured.
If ABS inter venes when braking, you will feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road
conditions and can ser veas a reminder totake
ex tra care while driving. Sy
