It indicates that the fuel tank cap of the vehicle is not properly closed, and it is recommended to check the fuel tank cap. The information and functions of the fuel tank cap are introduced as follows: 1. Drainage hole: The inclined design of the fuel tank opening is not for aesthetics but for environmental considerations to prevent rainwater accumulation. 2. Tire pressure value: Tires are the part of the car that directly contacts the ground, and their condition determines the driving safety. Generally, the safety of a tire can be judged by its air pressure and wear level. Many cars now have a label on the fuel tank cap that specifies the recommended tire pressure values under different loads. 3. Fuel grade: Since it is the fuel tank cap of the car, it naturally includes information about the fuel. If you want to know what grade of gasoline your car should use, you can find this information on the fuel cap. There are regulations on what grade of gasoline a car should use. Using a higher grade than necessary is not only unnecessary but also a waste of money, while using a lower grade can damage the engine's performance.
