Lights

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 use of headlamps varies due to legal requirements and self-imposed obligations. In these countries, dipped-beam headlamps are switched on when the ignition is switched on. In countries in which constant headlamp mode is not a legal requirement, you can perform this setting using the on-board computer.

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.
