My 2010 Impreza behaves in much the same way. Light comes on at a quarter tank, and when fuel gauge needle bottoms out you are out of fuel. It's not exactly where the needle points to empty though, the empty line is pretty wide. It's empty at the point where the indicator needle reaches the bottom of that line. There isn't any sort of peg, so you can't really be sure of how much fuel you have left, but at the same time the light motivates me to fill my car way before that point so I don't have to worry.
