If you're wondering how to open the fuel tank of your brand-new Benz, you're not alone. Many new owners struggle with this, especially given the absence of a lever to open the gas tank cover. The first thing to remember is not to panic and avoid using your keys or any other objects to force the cover open. Instead, look at your car's dashboard display and focus on the fuel gauge. The arrow next to the petrol machine sign will indicate which side the gas tank opening is located on. Once you've located the outside cover, simply push on the little door, and it should pop open. After that, just unscrew the gas cap by rotating it anti-clockwise and pulling it out when you hear a clicking sound.

What You'll Learn
Locating the fuel tank: Most cars have the gas tank opening on the driver's side
If you're driving a Benz, you don't need to worry about finding a lever to open the gas tank cover. Instead, simply locate the fuel tank by looking at your car's dashboard display. The fuel gauge will have a petrol machine or gas pump icon with an arrow pointing in one direction—the side the arrow points to is the side the gas tank opening is located on.
In most cars, the gas tank opening is on the driver's side of the vehicle. However, this is not always the case, as the placement of the fuel tank is influenced by the region or country of the manufacturer. For example, in America, where drivers sit on the left side of the car, the fuel tank door is usually on the left as well. In contrast, European manufacturers tend to place the fuel tank on the left side of the car since drivers sit on the right. Ultimately, the decision to put the fuel tank on the left or right depends on the positioning of the components beneath the vehicle.
If you're still unsure about which side your fuel tank is on, there are a few tricks you can use. One method is to look at the diamond-arrow on your fuel gauge, which indicates the side of the tank. If your car doesn't have this arrow, the hose on the icon should give you a clue. Additionally, some cars have a manual release for the filler door in the trunk, so you can check there if you're struggling to locate the tank.
Once you've located the fuel tank and opened the outside cover, you can unscrew the gas cap by rotating it anti-clockwise. You'll hear a clicking sound when it's ready to be pulled out. After refuelling, remember to put the gas cap back on and screw it in a clockwise direction until you hear the clicking sound again, indicating that it's locked in place.

Opening the tank: Push the little door to pop it open
If you're driving a Mercedes-Benz and are unsure about how to open the fuel tank, don't worry—it's a simple process.
First, you need to locate the fuel tank opening. This is usually on the driver's side of the vehicle, but not always. To confirm, look at your car's dashboard display and focus on the fuel gauge. The petrol machine sign will have an arrow pointing in the direction of the fuel tank opening.
Now that you've located the fuel tank opening, it's time to open the tank. This is the easy part. Simply push on the little door, and it will pop open.
Once the outside cover is open, you can unscrew the gas cap by rotating it anti-clockwise and pulling it out when you hear a clicking sound. After you've finished refuelling, remember to put the gas cap back on and screw it in a clockwise direction until you hear the clicking sound again, indicating that it's locked in place.
If you're having trouble opening the fuel tank and think it might be locked, there is usually an emergency release. In newer models, this is located behind the side panel of the interior. In older models, you could open the tank from the trunk side, but this may not be possible in newer models with electronic locks.

Opening without a key fob: Manually unlock the fuel door
If you're unable to open your Benz's fuel tank with your key fob, you can try manually unlocking the fuel door. This can be done by unlocking the driver-side door. In some models, the fuel tank cover will only open when the car is unlocked from the car's key remote or manually from the driver-side door. Manually unlocking other doors will not work.
If this does not work, you can try to locate the manual release by looking in the trunk. In some models, the cover on the right side of the trunk must be removed and the fuel door line requires vacuum pressure to unlock. You can use a vacuum to suck enough pressure through the lines to get it open without damaging the actuator.
If you are unable to locate the manual release, refer to your car's manual for specific instructions. It is important to note that you should not try to open the tank cover with your keys or any other thin solid object as this may scratch your car's paint.
Once you have successfully opened the fuel tank cover, remember to pay close attention to the gas cap's clicking sound. If you don't hear a click, your gas cap may need repair or maintenance. After refuelling, put the gas cap back on and screw it in a clockwise direction until you hear a clicking sound that indicates it is locked in place. Then, push the outside cover until you hear a sound that indicates it is locked.

Opening an older model: Open from the trunk side
If you have an older model of a Benz and are unable to open the fuel tank cover, there is a way to do so from the trunk side.
Firstly, remember that the gas tank cover will only open when you unlock the car from the car's key remote or manually from the driver-side door. Manually unlocking other doors will not work.
Now, to open the tank from the trunk side, you must remove the cover from the right side of the trunk and pull on the grasp. You can also try to feel the rubber part of the housing under which the button is located with your finger and press it.
If you are unable to open the tank using the above method, you can try using vacuum suction. Slowly increase the suction by closing your hand over the hose and the vacuum line (one that says "TD") while someone else pushes the fuel door.

Closing the tank: Screw the gas cap in a clockwise direction
Closing the tank after refuelling is a simple process. It is important to ensure that the gas cap is properly secured to avoid any potential fuel evaporation or spillage. To close the tank, simply screw the gas cap in a clockwise direction. You will hear a clicking sound that indicates the cap is locked in place. This is an important step to ensure that your vehicle is safe to drive.
The gas cap should be screwed tightly to create an airtight seal. This seal prevents fuel vapours from escaping and causing pollution. It also prevents any outside elements, such as dust or debris, from entering the fuel tank and potentially contaminating the fuel. A properly sealed gas cap helps maintain the optimal performance of your vehicle and ensures the engine receives the correct fuel mixture.
Additionally, a securely closed gas cap contributes to fuel efficiency. A loose or improperly sealed cap can lead to fuel evaporation, resulting in wasted fuel and increased fuel consumption. By ensuring the gas cap is tightly screwed on, you can maintain the optimal fuel economy of your vehicle.
In the event that you do not hear the clicking sound when closing the gas cap, it may be an indication that the cap requires repair or maintenance. It is important to address any issues with the gas cap promptly to avoid potential problems and ensure the overall maintenance of your vehicle.
Closing the tank by screwing the gas cap in a clockwise direction is a straightforward task that plays a vital role in the overall functionality and safety of your vehicle. It ensures the fuel system is secure and helps maintain the performance, efficiency, and environmental impact of your car.
