It's in the menus, but it is hidden. You need to scroll down to find the right bit. First time I went abroad I didn't look closely enough, and didn't use my close up glasses to see the menus in proper detail, and ended up driving around with the beams pointing the wrong way. Silly old me!
This from the Interactive Owners Manual -
Setting the dipped-beam headlamps for driving on the left/right
Press the
or
button on the steering wheel to select the Settings menu.
Press the
or
button to select the Light submenu.
Press
to confirm.
Press
or
to select the Dipped beams Setting for: function.
You will see the selected setting: Right-side traffic or Left-side traffic .
Press the
button to save the setting.
If you change the setting, conversion does not take place until the next time the vehicle is stationary.
This function is only available on vehicles with the Intelligent Light System.
You can use this function to switch between symmetrical and asymmetrical dipped beam
more .
If you set the dipped-beam headlamps for driving on the left/right, then motorway mode and the extended range foglamps are unavailable.
You can also have the dipped-beam headlamps set for driving on the right/left at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre.
There is not a lever in the headlamp, that was the previous model.
You can carry all the minor bulbs, in a pack, fancy MB or cheapy Lidl. The main beam bulbs though will need to be changed by a MB dealer anyway. I carry a message from MB which states that I asked about it and received that reply. Dunno what hapens if you get a tug (unlikely), I would expect to argue my way out (and procede immediately to a MB dealer)
They are not noted for failing, especially with a nearly new car.
