Don't worry I did this the first time I went to the gas station but my fuel release button was kind of far away for some reason. Just pull the seat up and take off the panel behind the seat and then the side panel. The gas release button should then be easily accessible.

 

When I was picking up my new '05 from the dealer, it wouldn't start when I turned the key. I started getting out of the car to tell the dealer my battery was dead and I wanted it tested for a short when I remembered the little red button...

You're only a newb for a little bit...
