yea the climate controls im slowly working out but its still somewhat mystifies me. there were some buttons like the rear interior light switch that i didnt understand at first(wouldve known sooner if there was a bulb in the light) except for the climate control and the dail by the lights that goes from 0 to 3 i seem to have got things figured out.
Not sure as I am new to the w116, I was a former owner of a Euro W126 and it had a dial that went from 0 to 3 next to the head light switch, it was for adjusting the headlights so that you did not blind the oncoming traffic. (higher nubmers due to number of people on board. Do you have the smooth one peice headlights? If so you may have a grey market Euro. I miss my W126 so I bought a 350se euro this week. Not sure if it has the adjustable headlights, as it is sitting in my X-wifes garage until I get the paperwork.
