ed . The adaptive light is contro lled automati­
cally, depending on vehicle speed and steering
wheel angle.
When driving a round bends, the head lights
are contro lled according to steering wheel an­
g le . So that there is no black area ahead of the
ve hic le, the two main beams pivot at different
angles. The system works above a speed of
about 6 mph (10 km/h).

- Automatic headlights a re only intended
to assist the dr iver. They do not re lieve
t he driver of his responsibi lity to check
t he headlights and to turn them on man­
ually according to the current light and
visibility conditions. For example, fog
and rain cannot be detected by the light
sensors. So a lways switch on the head­
lights under these weather cond itions
