Not having the luxury of an owner's manual written in English, I must appeal to the experts here from time to time in order to find out what some of the various switches and knobs are on my 84 300D Euro. On the center console, just below the climate adjusting wheel and to the left, is a 4 or 5 position knurled switch. The nomenclature depicts what looks like the side view of a headlight, and there are lines that indicate this light can be pivoted up or down. Changing the positions on the switch seems to have no effect on my headlights, parking lights, or for that matter, ANYTHING on/in my car. Any clues?
