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.
Information about driving abroad
Converting to symmetrical low beam
when driving abroad: switch the headlamps
to symmetrical low beam in countries in
which traffic drives on the opposite side of the
road to the country where the vehicle is
registered. This prevents glare to oncoming
traffic. Symmetrical lights do not illuminate
as large an area of the edge of the road.
Have the headlamps converted at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center, as close to the border
as possible before driving in these countries.
Converting to asymmetrical low beam
after returning: have the headlamps
converted back to asymmetrical low beam at
a qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center, as soon as
possible after crossing the border again.
