What does this button do??
 

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?

I would think specific seat controls would be on the side of the seat.

Since that location was seat heaters in the E53, and since front seat heaters are now two rows up with the HVAC system, I am guessing rear seat heat controls, left and right.

i think it's the active seats which slightly raise/lower the left/right side of the seat to keep you moving around a bit for long drives. there is no actual 'massage' feature.

I agree.

I thought that was only for the driver's seat...:confused:

Whatever you do don't push that button. It's the seat eject button! ;)

According to the UK brochure the Active seats button is below the front heated seats button on the AC unit. If you have the Active seat ventilation this feature is shared on the Front heated seat button on the AC unit.

The rear heated seat button is at the rear, as I understand from the brochure.

I wondered if it was anything to do with the four zone climate control option?

Thanks for the replies.
