i can't find it some body please help me

Hit the unlock button on the key fob twice and simply press on tha tank and it should open.

Lol, yeah I was confused the first time I pulled into a gas station either. I only accessed the gas tank from the outside. Just push on the tank, and it'll just flip open...very confusing I know....only car I've ever owned that did this.

look on the left side of the steering column, the center console, or the drivers door....those are the most common places they put the release switch

unlock all your doors and push the fuel door in and it should open ...
