A/C on with defroster???

[Heavy Metal Doctor]

I just got a Cube 1.8. and I have realized in the few days I've been driving it that sometimes the A/C switch is lit up "on" - it's cool enough I haven't needed it, so I kept turning it off and trying to figure out the exact circumstances that turn it on before I either take to the dealer to have something fixxed, or I look like an idiot complaining to the dealer about something that's not "wrong". I figured out that the vent setting is effecting this: either turning the a/c on at start up if the vent setting is already at defroster, or whenever you rotate the switch to defroster while driving.So, is this some new engineering thing to prolong the life of the compressor? Or is it actually wrong?.....oh, yeah, I did also RTFB (check the owners manual) and it didn't say anything more than to push the button to turn a/c on and the switch will light up.

EDIT:So it appears this is just the way they do it these days from some searching around the net (since noone posted a quick simple answer I spent my lunch time on the web) it's suposed to help clear the windsheild faster....whatever......shame on me for my next newset vehicle being a 97 (before this became a common feature) and thinking this is screwy way to do things!!! ....So I guess I'll figure out a bypass for this feature after the warranty runs out since I prefer air from the defroster vents most of the time.

Most cars turn on the a/c compressor to remove fog from the inside of the windshield. It works faster using the compressor.
