not switched on by the system in the low speed
range.
The system responds to the lights from oncom‐
ing traffic and traffic driving ahead of you, and to
ambient lighting, for example in built-up areas.
The high-beam headlights can be switched on
and off manually at any time.
If the vehicle is equipped with dazzle-free high-
beam assistance, the high-beam headlights are
not switched off for oncoming vehicles or vehi‐
cles driving ahead of you; instead, the areas of
the beam that would otherwise dazzle the on‐
coming traffic or traffic driving ahead are masked
off. In this case, the blue indicator lamp contin‐
ues to illuminate.
If the headlights are converted, see page 162,
high-beam assistance may only function to a
limited extent.

System limits
High-beam assistance cannot replace the driv‐
er's own judgement as to when to use the high-
beam headlights. Therefore activate the dipped
headlights manually if the situation requires it.
In the following situations, the system will not op‐
erate or its operation will be impaired and your
intervention may be required:
▷ In extremely unfavourable weather conditions
such as fog or heavy precipitation.
▷ When detecting poorly lit road users such as
pedestrians, cyclists or horse riders or car‐
riages and when trains or ships are close to
the road, or when animals are crossing the
road.
▷ On narrow bends, on steep hilltops or in de‐
pressions, when there is crossing traffic or if
the view of oncoming vehicles on a motorway
is obstructed.
▷ In poorly lit towns or where there are highly
reflective signs.
