WARNING
ARNING Risk of accident despite Adap-
tive Highbeam Assist Plus
Ad aptive Highbeam Assist Plus does not react
to:
R road users without lights, e.g. pedestrians
R road users with poor lighting, e.g. cyclists
R road users whose lighting is obstructed,
e.g. bya bar rier
On very rare occasions, Adaptive Highbeam
Assist Plus may failto recognise other road
users with their own lighting, or may recognise
th em too late.
In these, or in similar situations, the automatic
high beam will not be deactivated or will be
activated despite the presence of other road
users. #
Always obser vethero ad and tra1c con-
ditions carefully and switch o. the high
beam in good time. Ad
aptive Highbeam Assist Plus cann ottake into
account road, weather or tra1c conditions.
De tection may be restric ted in thefo llowing
cases:
R in poor visibility, e.g. fog, heavy rain or snow
R ifth ere is dirt on the sensors or the sensors
are obscured
Ad aptive Highbeam Assist Plus is only an aid. Yo u
are responsible for adjusting theve hicle's lighting

When Active Distance Assist DISTRONIC is activa-
te d, theve hicle speed will be adap ted accordingly
to thero ute events ahead. Depending on the drive
prog ram selected, theve hicle neg otiates a route
ev ent ahead in a fuel-saving, comfor table or
dynamic manner. When thero ute event has been
passed, theve hicle accelerates again tothe
stored speed. The set distance totheve hicle in
front, vehicles de tected ahead and speed restric-
tions ahead are take n into account.
Ro ute-based speed adap tation can be activa ted in

The following route events are take n into account:
R Bends
R Roundabouts
R T-junctions
R Turns and exits R
