What is the "A" in the vent icon?

[MikeC]

On the center display, it shows a closed arrow circle icon when it is set to "recycle" and an open arrow circle when it is set to "fresh" air. Sometimes I see the open arrow circle (i.e. "fresh air") with an A inside it. I feel like I should know this, but I don't. What does that signify?

I'd guess "Auto" when the option is set to automatic selection.

Automatic.

The car will select automatically whether to recirculate or introduce fresh air to achieve desired temperature.

Thanks. Just went and tested it out, very obvious - I probably should have figured that out a while ago!

I've noticed the car is not very good at figuring out recirculate or fresh air. Driving on city roads we have to manually select recirculate to prevent the exhaust from ICE from coming in the car. For some reason it seems to work worse in the S than other cars.

True.

I don't think it has the capability of making environmental air quality decisions like my BMW can.

I believe it only does it for temperature control.

My wife has complained about the same issue.

Yip. I asked in the test drive - the Model S doesn't have an air quality detector. Not that the feature really works that great on a BMW either (at least not on my dad's 535).
