Don’t feel dumb! Most cars have a release lever or button that gets you into the gas tank. The 2021 Acura TLX, however, has no button in the cabin. To open the gas tank on an Acura TLX from 2021, you just need to push on the right-hand side of the gas filler door.
The door has a spring-loaded mechanism that opens with a firm push. When you want to close the gas tank, push in the same area and it will lock into place. That’s all there is to it!
