Light switch

For reasons of safety, Mercedes-Benz recommends that you drive with the lights switched on even during the daytime. In some countries, daytime operation of headlamps varies due to legal requirements and self-imposed obligations. In these countries the dipped-beam headlamps are switched on automatically after the engine is started.

If you drive in countries in which traffic drives on the opposite side of the road to the country where the vehicle is registered, oncoming traffic may be dazzled by the asymmetrical dipped-beam headlamps. Have the headlamps changed to symmetrical dipped beam when driving in these countries. You can obtain information about this from any Mercedes-Benz Service Centre.
