There is no separate switch on the fuel tank cover of Cruze car, which is adjusted by the central locking of the vehicle. The fuel tank cover of Cruze can only be opened after the vehicle is unlocked. The fuel tank cover is located on the right rear side of the vehicle. When it needs to be opened, just push the fuel tank cover of the car to open it. After opening the fuel tank cover, slowly turn the inner fuel filler cap counterclockwise to open it. When refueling, the fuel filler cap can be stuck in the bracket on the fuel filler to prevent the paint surface from being damaged. After refueling, turn the filler cap clockwise until it clicks. Close the fuel tank cover of the car and finish refueling. Matters needing attention in the use of automobile fuel tank are as follows: 1. Don't turn on the yellow light to refuel Before driving, the car mainly looks at the fuel gauge and calculates whether to refuel on the way according to the distance and the scale of the fuel gauge. Car owners can refuel in advance, and don't wait for the oil lamp to light up before refueling. The oil pump is located in the fuel tank of the car. When the oil pump works continuously, the temperature is high, and it can be effectively cooled when immersed in fuel. When the oil lamp is on, it means that the oil level is lower than the oil pump. If you basically wait for the light to come on every time you refuel, the service life of the oil pump will be reduced, and if the oil storage capacity of the automobile fuel tank is too small, it may burn out the oil pump. 2. Choose whether to refuel in the morning or at night. Refueling time is tricky. In general, the temperature is relatively low in the morning and evening, and the gasification point of gasoline is relatively low. Naturally, you have to refuel sooner or later. Gasoline expands with heat and contracts with cold, and is charged by volume. At low temperature, the density of gasoline is relatively large, the mass per unit volume is also large, and there is more fuel; 3. When driving in urban areas, it is not recommended to fill up the car fuel tank. Usually, when driving in the city, it is not necessary to fill up the car tank. Because driving in the city always stops, if the car tank is full, it will increase the engine load and fuel consumption. It's convenient to refuel in the city, and it's easy to find a gas station. Of course, you don't have to fill it out.
