System limits
The high-beam Assistant cannot serve as a sub‐
stitute for the driver's personal judgment of when
to use the high beams. In situation that require
this, therefore switch off manually.
The system is not fully functional in the following
situations, and driver intervention may be neces‐
sary:
▷ In very unfavorable weather conditions, such
as fog or heavy precipitation.
▷ When detecting poorly-lit road users such as
pedestrians, cyclists, horseback riders and
wagons; when driving close to train or ship
traffic; and at animal crossings.
▷ In tight curves, on hilltops or in depressions,
in crossing traffic or half-obscured oncoming
traffic on highways.
▷ In poorly-lit towns and cities and in the pres‐
ence of highly reflective signs.
▷ When the windshield in front of the interior
mirror is fogged over, dirty or covered with
stickers, etc.
