Will the Mercedes-Benz C-Class automatically open the sunroof when submerged in water?

[DeTanner]

The Mercedes-Benz C-Class will not automatically open the sunroof when submerged in water; it needs to be opened manually. Escaping by opening the car door after the vehicle is submerged: After the vehicle falls into water, the body will not sink immediately, and the vehicle will not lose power right away. At this point, you should quickly unlock the electronic central locking system, unfasten the seatbelt, and open the door to escape swiftly. If the seatbelt cannot be unfastened, use a sharp object to cut it quickly. Escaping by breaking the window: If the vehicle has already lost power and you cannot open the doors or windows, choose to break the window to escape. When breaking the window, use sharp objects such as a safety hammer, detachable seat headrest, car fire extinguisher, or high heels, and start from the corners of the window. Note that the side windows and sunroof are the thinnest and relatively easier to break. Once the glass is shattered, the broken pieces will rush into the car with the water flow, so be careful to avoid being cut by the glass. After escaping the vehicle, keep your face upwards, hold your breath, swim to the surface, and seek rescue immediately.
