Looking for the Mazda gas tank button and finding no answers? That’s because most of the Mazda lineup allows you to simply press on the edge of the gas lid to pop it open and access the cap, which is a simple screw-off. As soon as you unlock the doors of your Mazda car or SUV, you have access to most models’ gas tanks. However, select models (such as the Mazda CX-5) do have a lever on the bottom left of their dashboard.
