lyte out of eyes using clean water.
R if electrolyte is swallowed, immediately
rinse out your mouth thoroughly. Do not
induce vomiting.

General notes
For reasons of safety, 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.
Convert the headlamps as close to the border as possible before driving in these countries
(Y page 263).
Asymmetrical dipped-beam headlamps Convert the headlamps back to asymmetrical
dipped beam as soon as possible after cross-
ing the border (Y page 263).
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
Setting options Exterior lighting can be set by:
R using the light switch
R using the combination switch
