I read the manual and info. online and still can't figure out whether the Compass is always in Auto. 4WD or is it in Two Wheel drive until you flip the "lock" switch. Our old KIA sportage was always in auto 4WD but when you pushed the lock button , it would lock it in. I read (online) that it was always in auto 4WD , then I'd read another article that said it was in 2WD until you hit the switch. I'm confused.
