Hello I have a Mercedes E320 cdi 2004 with xenon headlights, these can be adjusted for continental driving, inside each headlight is a small lever on the side of the head light bulb houlder, it has two positions up or down. I have had a look at mine and both levers are in the UP position, i read somwhere that this is the position for continental drive, but how can i be sure? does anyone know the correct position for the lever setting. I did ask the local Merc dealership but they were less than helpful, saying bring the car in and we will do it for you, i then tried another merc dealer and they said they did't know. Can anyone help here. regards Gary.
