How to Open the Fuel Tank Cap?
2 Answers
Methods to open the fuel tank cap: 1. Mechanical key opening. The mechanical key method is relatively complex, so it is rarely used in household cars nowadays. This method is usually found in more rugged SUVs, such as the JEEP Wrangler and Haval H5. 2. In-car switch button. The more common method now is the in-car switch button, which is more convenient compared to the mechanical key method. It has been widely used in fuel vehicles for a long time. However, it can easily lead to refueling without turning off the engine, so car owners need to be extra careful. 3. Direct press-to-open. This method is the most convenient among the three fuel tank cap opening methods, requiring no operation from the car owner. The fuel attendant can directly refuel. For cars using this method, the owner must ensure the car is locked when parked; otherwise, the fuel tank cap can be opened if the central control is not locked (similar to the trunk), posing certain risks.
I've been driving for almost twenty years and frequently encounter this situation. The general procedure is to park the car and turn off the engine, then locate a small button near the driver's seat by the door with a fuel pump symbol. Press it gently, and upon hearing a click, the fuel tank cap will open. Some older cars don't have a button; instead, there's a keyhole on the cap—just twist it with the car key. Be careful not to press or twist too hard to avoid damaging the parts. The fuel tank cap can be on either side, so make sure you park correctly to avoid confusion. After refueling, press the cap firmly until you feel it click into place; otherwise, fuel odors may seep into the car, which is unpleasant. Regularly check the button's flexibility and the seal around the cap to prevent rust or jamming issues. A pro tip: always glance around for potential fire hazards before operating—safety should never be overlooked.
