on the driver's side automatically go into anti-
dazzle mode if the following conditions are
met simultaneously:

ynotes
For reason sofsafety, Mercedes-Benz recom-
mends that you drive with the lights switched
on even during the daytime. In some coun-
tries ,operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations. 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.
Conver tthe headlamps as close to the border
as possible before driving in these countries
(Y page 223).
Asymmetrical dipped beam Convert the headlamps back to asymmetrical
dipped beam as soon as possible after cross-
ing the border (Y page 223).
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. Setting the exterior lighting
