In the car where is the button so you can get gas?
I believe you are asking????? where is the gasoline(fuel) cap release door lever....on most vehicles it is a handle displaying the picture of a fuel pump on the left side of the drivers seat floor area between the front side of the drivers seat and the drivers door, lift it gently up and the door will open to the fuel cap compartment. Be certain to screw the fuel cap on tightly after getting gas or else your check engine light will come on after a short while driving and can cost upwards of $100.00 to have it reset by the dealer.
