How to open the fuel tank cap of Mercedes-Benz V-Class V260?

[StJoanna]

The fuel tank cap switch of Mercedes-Benz is linked with the car door. When the door is opened, the fuel tank cap is automatically unlocked, and it can pop out with a light press. First, remove the lining board covering the fuel tank in the trunk, take off the inner lining board, and pull the cable to open the fuel tank cap.

Last time I drove my friend's V260 to refuel, I encountered the same issue and it took me a while to figure it out. The fuel tank cap design on Mercedes-Benz commercial vehicles like this is particularly user-friendly—no need to search for any buttons. First, turn off the engine and use the key or press the door unlock button to release the central locking. Then, walk to the right rear side of the vehicle where the fuel tank cap is located. Simply press firmly with your finger on the textured area above the cap, and you'll hear a click as it pops open. If it's too cold and frozen to press, don't force it—pour some warm water to thaw the ice and try again. When closing the cap, make sure it aligns with the slot and wait for the audible click to confirm it's securely locked. Once, I didn't close it properly, and the warning light scared me—the spring on this fuel tank cap is much stronger than those on regular sedans.
