Where is the fuel door release for Mercedes Benz 2003 clk 320 convertible?

It should be the same as my 2001 CLK. Just make sure the car is not locked as the doors and fuel door all lock together when you send the lock signal. Lightly press the forward quarter of the fuel door and it will swing open. The door is not hinged at one end like a gate. It is hinged off-set from the edge about two to three inches. Cool huh?
