I had some cargo in the back with the seats folded down recently. I got tired of the seatbelt warning for the back middle seat so I tapped the "child seat" icon so that it would stop warning me about the child seat (as we all do). The problem is that now that the seats are back up, I have no idea how that turn the child seat off. This setting used to appear where the trip and psi cards lived... I can't seem to find it in V11 at all.
