What are these buttons for?

[Vinchenzo51]

now i KNOW i'm going to get made fun of for this, but I don't have an owners manual and just bought the car last monday.

what is the difference between the circular arrow button, econ button, and circular arrow button with the "a" in the circle?

as long as i figure out what these button do i'll be OK with the ridicule


p.s., i did search for this before posting, so i made the conscious effort

circular arrow = recycle air... to keep the stink outside... or inside ;-P ...also the same as a "MAX A/C" function found on other makes.
econ. button = a/c compressor off.
mine does not have the "a" w/circular arrow, but i assume that one would be "recycle air/auto climate control".

a with the circular automatically recircullates (sorry for spelling) the air when it detects pollutants and stuff like that. says my owners manual.

It is like BMW, there is some kind of sensor sitting near air filter that detects pollutants and therefore the AC system can, if you allow it, switch into recirculate mode until the air clears.
