They are the air vents for the back. The connect to the box in the center of the dash. When you use the "floor" setting, it sends air to the back through the vents. If you pull up the rug, you'll see where they go, but you can actually see where the vent goes from the front to those if you look at the rear corner of the front mats....its kinda raised. In the pic, its #10
