I just recently got a 99 e320 (unfortunately no manual) but i cant seem to figure out how to reset the 3 seat memory options. i cant seem to get the seat to move back by the controls, but as soon as i press one of the setting keys, it moves into that position. its really annoying because right now i am forced to sit in somewhat of a position that i can tolerate. can anyone help? also did the 99's not come with seat warmer options?
