Is it normal to have the Auto climate control feature always turn on the AC? It's been extremely cold (and accompanying low humidity of course) and sometimes I'll drive for awhile not remembering to turn the A/C off. Also would be nice if the A/C 'on' light was a bit bigger, or the A/C button also lit up etc., so I (or my wife) don't miss it. Most cars I've had/driven do usually turn the A/C on for most conditions, but not for all conditions.
