Let's see how to open the fuel flap of a Citroen C4 Cactus. Press firmly on the point where the locking mechanism is located - usually on the edge - which works like a push button: by pressing, the flap unlocks and opens slightly.

To remove the actual cap, you will need the car key (the one used to start the engine). Insert the key into the cap lock and turn to unlock and remove it. After refuelling and screwing the cap back on, locking it with the key, press again until you hear the click of the mechanism engaging.
