i dont think any of them have an actual reserve tank, in the wagons and in sedans there is a vacuum reserve tank which is black plastic. and in the wagons there is a windshield washer tank which is white plastic. i have never seen a reference to a reserve fuel tank or an overflow tank.

brian is correct in saying it is only in the main tank. the warning light is to tell you you are near the end.
