You dont have a heated front screen. That button is for rear window and auxiliary elements. You only have heated wing mirrors and heated washer jets. If you have rear windows with elements, the button will also operate those too.
Another way to prove this, is to look closely at your windscreen and see if you can see loads of thin black wiggly lines going vertically down. These are the heating elements. My LX has two buttons, one for the front screen, and the other - which is the same as yours, for the mirrors and water jets. I do not have heated rear windows.
Hope this clears things up a bit.
