Ok this is my first sxs and all of this is new to me. I have a 2015 900xp with only 7 miles on it and I notice that when I put it in turf mode (the switch all the way down) the icon for the locked rear diff comes on in the display. If I put in the rear locked position (switch in the middle) the diff locked icon goes off. In my mind this is backwards. Is this normal or is something wrong with my machine?
