The Air Quality button engages the two sensors which are mounted under/behind the front bumper and monitor hyrdocarbons and fine particulates, and when engaged, AQ will automatically switch the damper which controls the introduction of outside air OR (if outside air is too polluted) recirculation. The Recirc. button (Air Intake Control) itself overrides the AQ and lets you decide.
And if AQ or you decide to run the cabin on recirculate most of the time, it would tend to extend the life of the filter as less outside air (bugs, dust, whatever) would be passed through the filter. All air which enters the cabin passes through the filter, but if you don't smoke in the car and keep the theoretically dirtier air outside by using Recirc., there would be less crud to be filtered (but the cabin might get a bit stuffy).
The bi-level vents (warmer low, cooler upper) are likely processor controlled according to the requested temp. setting you choose and according to the humidity inside the car, where, in Winter, you might want warmer feet, but the cabin humidity might occasionally call for some air conditioned air to take the fog off the windows. Don't know of any operator controls that would let you vary the top/bottom temps, in a like manner to the driver/passenger temp. controls...

Thanks for the prompt and thorough response. Makes more sense now.
