abroad The asymmetrical headlight beam
extends visibility at the edge of the
road at the passenger side.
However, when driving in countries
where traffic drives on the opposite
side of the road, adjust the headlights
to prevent dazzling of oncoming
traffic.
Vehicles with halogen headlight system Have the headlights adjusted by aworkshop.

For deactivation, operate the same
procedure as described above.
Control indicator B will illuminate for
approx. 4 seconds when the function is deactivated.
Adaptive forward lighting
Adaptive forward lighting ensures
better illumination of bends, crossings
and narrow bends.
Dynamic curve lighting
The light beam pivots based on
steering wheel angle and speed,
improving lighting in curves.
Corner lighting
On tight bends or when turning off,
depending on the steering angle or
the indicator light signal, an additional left or right reflector is switched on
which illuminates the road in the
direction of travel. It is activated up to
a speed of 25 mph.
