Flap above aircon filter - position?

[kevinj93]

Generally, recirculating the air will provide better cooling rather than drawing in hot, outside air. Of course, if the Yaris has heat soaked, sitting in the sun, the outside air will initially be cooler. My normal procedure if the car has been parked in the sun is outside air until the cabin starts to cool, then switch to recirculate.

My understanding (and I may be wrong) is that the recirculated air will be cooler than the hot fresh air, and the air condityioner does not have to work as hard to keep it cool.
