When I first bought my Mercedes-Benz C200L, I had a little funny moment: how do you open the fuel tank cap? After fumbling around for a while, I realized it wasn’t like the older cars I’d driven—there was no external lever. You have to sit in the driver’s seat, find the small button with the fuel pump icon on the door panel, press it for a few seconds, and wait for the ‘click’ sound before the fuel cap pops open automatically. Mercedes designed it this way for anti-theft and anti-misoperation purposes, making refueling safer. If the button doesn’t respond, it might be because the car isn’t unlocked or the battery is dead—don’t force it; just check if the key is within the sensing range. I remember the first time I randomly pressed buttons near the rearview mirror and ended up activating the windshield wipers—hilarious! Now that I’m used to it, I find this electronic control super convenient, especially on rainy days when I don’t have to fumble with the cap in the rain.
