trians, cyclists and animals.
Active: when the lights are switched on.
Cornering light function The cornering light function improves the illu-
mination of the road over a wide angle in the
direction you are turning, enabling better vis-
ibility in tigh
tbends, for example. The corner-
ing light function can only be activated when
the dipped-beam headlamps are switched on.

40 km/h or switch off the turn signal or turn
the steering wheel to the straight-ahead posi-
tion.

R
if you are driving at speeds above
110 km/ha nd do not make any large steer-
ing movements for 1000 m
