The Toyota Yaris is a great car. They seem to be much less tinny than a lot of the other little cars I’ve had over the years. They are also a bit different in other ways too. When you first buy a Toyota Yaris you might be thinking to yourself, where the hell is the petrol cap release button..I was when I first bought mine. I was also close to running out of petrol at the time.
Well, there is a little lever button that you pull up with your finger to release the fuel cap lock. It’s located on the right side (UK) (Left side US) of the drivers seat, right at the bottom.
Just look down the side of the seat to the floor and you will see it. Here’s a picture in case you are still baffled and having trouble finding it. Click the picture to enlarge. Not sure if this is the same location used on newer models of Toyota Yaris.
