I do find it annoying thought that, for example when I put it in Snow mode, that when I shut off the vehicle and start driving again, it goes automatically goes back to normal but leaves the vehicle in 4A. Seems dumb, if you're going to default back to Normal each time, then go back to 2W as well. Otherwise, stay in the mode I put you in to begin with.
I prefer it this way, but not for my wife. After she fishtailed over 90 degrees turning onto an expressway on a rainy day, I prefer that she won't be in 2WD mode unless I'm driving it on occassion.
