Automatic Climate Control air distribution

I checked the owner's manual but could not find any reference:

When I run the climate control on auto setting, I notice the air is distributed only to the upper vents (no air to the lower section to your feet). If I manually override the automatic function, I can direct the air to any area. At least this is how it seems to be operating when blowing cold AC. I did not have the car yet during Winter (yet) to be able to check it. Anyone else notice this?

Try raising the temperature. The air will come out from the lower outlets.

So are you saying that it only comes out the lower vents (in auto mode) when the heat is on?

yeah, they taught the computer physics :P

cold air falls so it gets shot out the top vents

hot air rises so they put it through the bottom ones
