When I use the auto climate control, the screen always shows that it is set to recirculate. I'm wondering how accurate that is. On my Malibu there were lights for inside/outside air, and when I had it on auto, neither light was ever one. The mechanic told me that auto simply uses whichever is best for the given conditions, but I could never understand why the Malibu didn't show me which one it was using. Is the same true for the Nox?
