110 Light and visibility
Cornering light
Cornering light function
The cornering light improves the illumination of
the road over a wide angle in the turning direc‐
tion, enabling better visibility on tight bends, for
example. It can be activated only when the low
beam is switched on.
The function is active:
At speeds below 25 mph (40 km/h) when
R
the turn signal light is switched on or the
steering wheel is turned.
At speeds between 25 mph (40 km/h) and
R
45 mph (70 km/h) when the steering wheel
is turned.
Traffic circle and intersection function: the
cornering light is activated on both sides through
an evaluation of the current GPS position of the
vehicle. It remains active until after the vehicle
has left the traffic circle or intersection.
Adaptive Highbeam Assist
Function of Adaptive Highbeam Assist
& WARNING Risk of accident despite
Adaptive Highbeam Assist
Adaptive Highbeam Assist does not recog‐
nize the following road users:
Road users without lights, e.g. pedes‐
R
trians
Road users with poor lighting, e.g.
R
cyclists
Road users whose lighting is obstructed,
R
e.g. by a barrier
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.
System limitations
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Detection may be restricted if:
Visibility is impaired, for example in fog,
R
heavy rain or snow.
There is dirt on the sensors or the sensors
R
are obscured.
Adaptive Highbeam Assist is only an aid. You are
responsible for adjusting the vehicle's lighting to
the prevailing light, visibility and traffic condi‐
tions.
