Hello motor-talker, when setting the electr. adjustable driver seat of my new SD4 Dynamic I noticed that the horizontal button for this purpose can be moved to the left/right (for seat adjustment to the front/back) and to the right/down (for height adjustment of the entire seat), but has no function on the left-hand side of the button. Here it should be possible to move according to operating instructions up/down to the angle of the seat cushion. The function didn’t work here either (and the friend didn’t have his best man in use, who knows the car inside and out), so it seems to be a flawed description in the manual?!? Or how did you have this function set up with you? Thanks for a feedback. Greetings El Miguel
