Roewe 550's fuel filler switch is connected to the central door locking system. When the door lock is open, press the right side of the cover to open it, then slowly rotate the fuel filler cap counterclockwise to open it. After refueling, reinstall the fuel filler cap and tighten it until you hear three "clicks". Generally, there are three ways to open the fuel filler cap of a family car: using a key, an interior switch, or direct pressing. The mechanical key method is more complicated, so few family cars use it nowadays. Roewe 550 adopts the direct pressing method. For cars with this type of fuel filler cap, the owner must ensure the car is locked when parked; otherwise, the fuel filler cap can be opened if the central locking is not engaged, which poses certain risks. Ways to open the fuel tank: If the automatic unlocking function of the fuel filler flap fails mechanically, the flap can be manually opened using the emergency switch inside the trunk. Remove the right interior panel in the trunk to access the fuel filler flap release cable. The mechanical key method is more complicated, so it is rarely used in family cars today, but it is more common in rugged SUVs like the Wrangler and Haval H5. The interior switch method is now more common, featuring a button inside the car, which is more convenient than the mechanical key method. However, this can lead to refueling without turning off the engine, so owners need to be extra careful. The direct pressing method is the most convenient of the three fuel filler cap opening methods, requiring no action from the owner, allowing the fuel attendant to refuel directly. For cars with this method, the owner must ensure the car is locked when parked; otherwise, the fuel filler cap can be opened if the central locking is not engaged, posing certain risks.
