I haven't been able to change the Air intake from Fresh Air to Recirculate. From what I read in the manual I think it should change easily but I can't. I do keep the Air on Automatic if this is a control parameter.

Can anyone help me out? There are times when I do not want to smell the blue smoke special ahead of me in traffic. Then the air is decidedly not fresh.

 

you push the center button and nothing happens? It will only stay that way til you turn the car off, btw.
