How do I turn off the AC in 2007 Audi A6 Quattro? I cannot seem to figure out how to turn it off completely, only turning it down to fan speed 1. There are times I'm interested in driving with the windows open and not using the AC at all, yet I keep having the air blow.

Seems silly and am hoping someone can shed some light.

Thanks in advance.

 

Press and hold "Econ on/off" button a few seconds.

 

Thanks.
