Passenger seat- theres a button on the side of the seat,a wheel,i've played about with it but nothing happens,just curious about its function,does the passenger side have active bolsters?i read somewhere it did but obviously i could have misunderstood.. I have tried searching passenger side buttons but no luck,sorry if this has been previously discussed. Thank you all

 

That is the power lumbar support button. It should be working and emits a quiet motor noise. No active bolsters on passenger seats anymore. The driver's seat has all the goodies with the bladders and that's it.

 

Yea I believe active lumbar nad possibly lateral bolsters. Should be able to hear the air pump operating when manipulating it.

 

Lumbar support...
