Mercedes-Benz trunk has two control buttons, one on the driver's side door (behind the window button), and one on the trunk lid (right above the license plate position). Methods to open or close the trunk lid: The Mercedes-Benz trunk lid features an automatic opening/closing function, which is driven by a hydraulic electric system to activate the automatic lifting of the trunk lid. The trunk can be opened or closed either electrically or via remote control. To open the trunk, simply press the button inside the car or on the remote key, and the trunk will open automatically. To close the trunk, press the close button inside the trunk, the close button inside the car, or the remote key, and the trunk will close automatically. Functions of the trunk: Generally, the trunk contains items such as the car's spare tire, first aid kit, onboard tool kit, triangle warning sign, fire extinguisher, emergency fuel tank cap release cable, etc., for emergency use.

After driving a Mercedes for so many years, I can find these two buttons with my eyes closed. The exterior button is located above the license plate frame—just crouch down slightly to see it. It's a square rubber button; a gentle press opens the trunk. The interior button is usually in the driver's cockpit, among the row of buttons to the left of the steering wheel—look for the one with the trunk icon. Some models might place it near the storage slot below the center console. Honestly, Mercedes designs are quite user-friendly: the interior button lets you open the trunk at traffic lights, while the exterior one is handy when your hands are full. Don’t forget the emergency release handle inside the trunk, tucked in the inner groove—it could save your life if you ever get locked inside.

When I first got my new car, I also spent quite some time figuring it out. Now let me tell you the exact locations. The rear control button is right along the upper edge of the license plate frame, made of waterproof material so it works fine even in rain. The button inside the cabin is usually on the left side of the instrument panel, sometimes near the door pocket storage compartment. These two buttons have distinct functions: the exterior one requires a 1-second long press to deactivate the anti-theft system, while the interior one can be used anytime. I recommend turning on the engine and looking carefully when searching for them the first time—Mercedes interiors have dim lighting, and the buttons are designed to be very subtle. By the way, there's also a white pull ring inside the trunk; pulling it from inside unlocks the trunk in emergencies—this design is especially reassuring.

I also encountered this issue when buying a car, and it's actually quite simple. The exterior button is located in the middle of the license plate light—just look down to see a small silver square. The interior one is hidden behind the left side of the steering wheel; you'll need to turn your head and look down to the left. Both buttons function identically, as they're electronically controlled. The exact position may vary slightly between different models, with SUVs possibly having larger buttons. If you can't find it, turn on the reading light to illuminate the area and look for a circular indicator near the metal trim. Additionally, don't forget to use the trunk button on your car key—holding it down will automatically pop open the trunk, which is even more convenient than using the buttons.

As a frequent delivery driver and Mercedes owner, I use these two buttons every day. The most frequently used one is the exterior button, located right above the license plate on the rear bumper at waist height for easy access. The driver's side button is next to the light control area, usually placed together with the fuel filler flap button. I've developed a habit of pressing the interior button to unlock when parking, and using the exterior one when loading goods. I also discovered a handy trick: with mid-to-high trim Mercedes models, simply waving your foot under the rear bumper while carrying the key will open the trunk, which is even more convenient than using the buttons. The waterproofing of these buttons is crucial, so remember to check for moisture ingress after car washes.
