Exterior lighting
General notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switched
on even during the daytime. Therefore, your
vehicle is equipped with special daytime driv-
ing lamps. In some countries, operation of the
headlamps varies due to legal requirements
and self-imposed obligations.
Driving abroad
Symmetrical dipped-beam headlamps
If your journey takes you to countries where
vehicles are driven on the opposite side of the
road to the country in which the vehicle is
registered, your headlamps must be switched
to symmetrical dipped beam. This prevents
oncoming traffic from being dazzled. Sym-
metrical lights do not illuminate as large an
area of the edge of the carriageway.
Convert the headlamps as close to the border
as possible before driving in these countries
(
Y page 256).
Asymmetrical dipped-beam headlamps
Convert the headlamps back to asymmetrical
dipped beam as soon as possible after cross-
ing the border (
Y page 256).
If the headlamps are converted to symmetri-
cal dipped beam, the "motorway mode" and
"extended range foglamps" functions (Intelli-
gent Light System) are not available.
