Why does the “Auto” mode in car climate control change the zone to “feet only” and then slowly change to “feet + torso”.
Normally, hot air comes out of the footwells, and cold air comes out of the face vents. That's because hot air rises, so by pumping it out of the footwells it will rise into the rest of the car. If it came out higher up, it would be difficult for it to heat the lower parts of the cabin.
The Short Answer
Normally, hot air comes out of the footwells, and cold air comes out of the face vents. That's because hot air rises, so by pumping it out of the footwells it will rise into the rest of the car. If it came out higher up, it would be difficult for it to heat the lower parts of the cabin. And vice versa for cold air. > Why does the "Auto" mode in car climate control change the zone to "feet only" and then slowly change to "feet + torso". I would expect this to be true if the car is cold to start with, because it's pumping out hot air at first. As the car warms up, the air it pumps out is no longer hotter than the air already in the car, so there's no need to pump it all out near your feet any more. But if you get in a hot car then the air conditioned air should come out the face vents right from the start.
