Both AC controls and volume are on touch-sensitive buttons on the new VW entertainment systems. The volume bar/AC temperature buttons don't even light up at night, making it completely invisible under the bright touch screen. Once in a while, the system locks up, and you can't change AC anymore (can't turn it on/off, can't change the intensity). You have to shut down the engine, walk away from the car (with the key) for more then 20-30 meters and then wait 10 minutes. I love my Seat Leon for many reasons, but the lack of buttons is not one of them.
