Can anyone tell me what the button does in the lower set of buttons at the right far end in the picture.


The button is on the lower row, under the man's finger and at the end of the buttons with the DSC button it. I know there is one on either side of the row. I know is not heating or active ventilation, maybe its the rolling massager I dont know?

Also what about the blank switch next to it (on the left) what is this for?

Would appreciate anyone out there with the new X letting me know?
