Where is the fuel tank cap switch on a Mercedes-Benz?
2 Answers
Mercedes-Benz fuel tank cap switch is located at the lower left side of the driver's seat. You can reach it by extending your left hand down. It features a two-button design - one for opening the trunk and another for opening the fuel tank cap. Simply press to open. Fuel tanks can be divided into two types: open tanks and closed tanks. The tank must have sufficient capacity. To maintain oil cleanliness, the tank should have a sealed cover plate equipped with an air filter. Mercedes-Benz is a German automotive brand renowned for luxury and high performance, headquartered in Stuttgart, Germany. It is a member of Daimler AG, producing various passenger vehicles and medium-to-large commercial vehicles.
I usually drive a Mercedes, and my experience with finding the fuel filler cap release is that it's typically located on the interior trim panel of the driver's side door. You can spot a small button as soon as you open the door—just press it, and the fuel cap pops open. However, there are differences between older and newer models. For E or S series, the release might be more discreetly placed, like a small lever on the control panel below the steering wheel, easily reachable while seated. Why is it designed there? I think it's for safety and convenience, avoiding the need to bend over. If you can't find it, don’t worry—first, make sure the doors are unlocked, as the fuel cap lock only opens when the car is unlocked. Always remember to turn off the engine before operating to prevent accidents. Some friends complain about the button not responding, which could be due to a blown fuse or poor electrical contact—best to have it checked at a repair shop. My advice is to quickly scan the relevant areas (door panel and around the steering wheel) before driving. If all else fails, check the owner’s manual or search online for model-specific details. It’s a common mix-up but not hard to resolve.
