I have no experience working on Mercedes autos, so when I bought a
used 1982 300sd which had no owners manual with it, I was stumbling
upon the correct actions needed to move the power mirrors, ac unit,
windows, sunroof, etc. I still haven't found the buttons or levers to
move the front seats back to allow more room for my size 13 feet to
fit under the dash. How does one accomplish this task?
