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 running lamps.
In some countries, operation of the headlamps
varies due to legal requirements and self-
imposed obligations.
If you wish to drive during the daytime without
lights, switch off the daytime running lamps
function in the on-board computer
( page 206).
