How to Open the Fuel Tank Cap of a Mercedes-Benz?
3 Answers
After unlocking the vehicle, press the fuel tank cap to open it. Here is some information about the Mercedes-Benz fuel tank cap: 1. The fuel tank cap refers to the square-shaped box on the car made of stainless steel for storing gasoline. It has excellent sealing with only one circular inlet, which is about the size of a bottle cap for easy storage. It is usually located at the rear of the vehicle. 2. Mercedes-Benz uses an integrated central locking system. When the car door is unlocked, pressing the fuel tank cap will open it. When the vehicle speed exceeds 8 kilometers per hour, the fuel tank cap will automatically lock, just like the doors.
Yesterday at the gas station, I saw a guy driving a Mercedes circling his car looking for the button. Actually, it's quite simple. For Mercedes with a mechanical fuel cap, just press the right edge of the fuel cap directly with your hand, and you'll hear a click as it pops open. Newer Mercedes models mostly have electronic controls, which is even more convenient—just walk to the fuel tank with the car unlocked and press the cover directly, similar to pressing to unlock a smartphone. Remember, you don’t need to remove the entire cap when refueling; the flip-top design allows you to push it all the way down to refuel. If it doesn’t pop open, first check the door locks, as some cars require the entire vehicle to be unlocked for it to work.
Three years of driving the E-Class: The fuel filler flap switch is linked to the door locks. There's no dedicated button near the start/stop switch—simply turn off the engine, unbuckle your seatbelt, and lightly press the top-right corner of the fuel flap to open it. Two key points to remember: 1) The doors must be unlocked (you'll hear the unlocking sound); 2) Don't attempt this with the engine running—the electronic lock won't release. Last time at the gas station, I saw a flustered woman forcefully inserting her fuel card the wrong way into the flap, which actually doesn't require card insertion at all.
