The Cruze model does not have a separate fuel tank cap switch. The fuel tank cap is controlled through the vehicle's central locking. The fuel tank cap can only be opened when the vehicle is unlocked. The Cruze's fuel cap is located on the rear right side of the vehicle. When you need to open it, you can open it by pushing the fuel tank cap. After opening the fuel tank cap, slowly turn the inner fuel filler cap counterclockwise to open it. The fuel filler cap can be clamped in the bracket on the fuel filler door when refueling to avoid damaging the car paint. After adding oil, turn the oil filler cap clockwise until you hear a "click" sound. Refueling is completed by closing the fuel tank cap.

Precautions for the use of the fuel tank are as follows:

1. Do not turn on the yellow light before refueling. Car owners should check the fuel gauge before driving and calculate based on the distance traveled and the scale of the fuel gauge. If you need to refuel on the way, car owners can refuel in advance instead of waiting for the oil light to come on. The oil pump is located in the fuel tank. The temperature of the oil pump is relatively high when it is continuously working. Being immersed in fuel can effectively reduce the temperature. When the oil light is on, it means that the oil level is lower than the oil pump. If you wait for the light to come on every time before refueling, the service life of the oil pump will be shortened. If there is too little oil in the oil tank, the oil pump may be burned;

2. Choose Refuel in the morning or evening, the timing of refueling is tricky. Under normal circumstances, the temperature in the morning and evening is relatively low, and the vaporization point of gasoline is relatively low, so refueling should be done in the morning or evening. Gasoline expands with heat and contracts with cold, and gasoline is charged by volume. When the temperature is low, the density of gasoline is relatively high, the mass per unit volume is also relatively large, and more fuel is needed;

3. It is not advisable to fill up the fuel tank when driving in urban areas. When driving in urban areas, there is no need to fill up the tank. You must fill up the fuel tank when necessary, because driving in urban areas is always stop-and-go. If you fill up the fuel tank, it will increase the load on the engine and increase fuel consumption. It is very convenient to refuel in urban areas, and you can easily find gas stations. So there is no need to top up.
