As long as we're talking about buttons, when I push the button (I think it's below the AC button) that (I assume) recirculates the air (the red light goes on) instead of allowing it to come from outside, it automatically shuts off in a very short period of time...maybe 10 minutes? Which, in traffic, is not enough to get me through some of the cow towns (literally) around here...stinky!

Is that the way it's supposed to work?
