Important safety notes
For reasons of safety, Mercedes-Benz
recommends that you drive with the lights
switched
on even during the daytime. In some
countries, operation of the headlamps varies
due to legal requirements and self-imposed
obligations.
If you wish to drive during the daytime without
lights, switch off the daytime running lamps
function in the on-board computer
(Y page 224). Driving abroad
Symmetrical low-beam headlamps Switch the headlamps to symmetrical low
beam in countries in which traffic drives on
the
opposite side of the road from the country
where the vehicle is registered. This prevents
glare to oncoming traffic. When using
symmetrical lights, the edge of the road is not
lit as widely and as far ahead as normal.
Have the headlamps converted at a qualified
specialist workshop as close to the border as
possible before driving in these countries. Asymmetrical low-beam headlamps Have the headlamps converted back to
asymmetrical low-beam headlamps at a
qualified specialist workshop as soon as
possible after crossing the border again.

You can use this function to set the
headlamps
to change between low beam and
high beam automatically. The system
recognizes vehicles with their lights on, either
approaching from the opposite direction or
traveling in front of your vehicle, and
consequently switches the headlamps from
high beam to low beam.
The system automatically adapts the low-
beam headlamp range depending on the
distance to the other vehicle. Once the
system no longer detects any other vehicles,
it reactivates the high-beam headlamps.

the windshield near the overhead control
panel. Switching Adaptive Highbeam Assist
