How to Open the Fuel Tank of an Automatic Transmission Car?

[Grant]

This type of fuel tank cap is opened using a dedicated fuel tank cap key. First, you need to lift the fuel tank cover, then insert the key, and finally turn it counterclockwise to open the fuel tank cap. The switch for the built-in locking fuel filler cover is usually located under the driver's seat, and the switch is marked with a fuel pump icon.

I remember driving automatic transmission cars for over ten years, and opening the fuel tank is a routine step every time I refuel. In my car, there’s usually a small lever or button under the driver’s side door, easily reachable by hand. A gentle press or pull will trigger an unlocking sound, indicating the fuel cap is released. Then, I step out of the car, walk to the rear, and press or twist the round cap to open it. In winter, if it’s frozen and stuck, I gently pry the edge with a key or use de-icing spray to avoid forceful damage. At the gas station, always ensure the engine is off and the car is parked away from any ignition sources to prevent accidents. Regularly keeping the mechanism clean prevents dust buildup and ensures smooth, safe operation.
