General notes
For reasons of safety, Mercedes-Benz recom-
mends 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. Driving abroad
General notes 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 reg-
istered, your headlamps must be switched to
symmetrical dipped beam as soon as possible
after crossing the border. This prevents oncom-
ing traffic from being dazzled. Symmetrical
lights do not illuminate as large an area of the
edge of the carriageway.
Vehicles with halogen headlamps X
Turn cap :anti-clockwise and remove it.
X Push switchover lever ;down.
X Replace cap :and turn it clockwise.
Convert the headlamps back to asymmetrical
dipped beam as soon as possible after returning across the border.

Before crossing the border, set the head-
lamps to symmetrical dipped beam and after
returning back to asymmetrical dipped beam via the "Dipped-beam headlamps for driving
on the right/left" function in the on-board
computer (Y page 252). If the headlamps are converted to symmetrical
dipped beam, the "motorway mode" and "exten-
ded range foglamps" functions are not available. Setting the exterior lighting
