I'm not positive on the 2003, but I do think that means you don't have traction control.

There is a switch by the drivers left leg that raises and lowers the spoiler on the Boxster.

I believe that center plastic piece is also shared with the 996 Carrera (1999-2004). For that car, that might be were the default location of the spoiler control is. It's also were the rear wiper button goes now that I think about it.

And the big circle on the bottom is where the lighter goes for right hand drive cars, in case you are wondering.
