This vehicle does not have an interior fuel tank switch. The entire series of this car features an induction lock for the fuel tank cap, requiring manual opening after exiting the vehicle. The fuel tank cap is located on the right side, which corresponds to the passenger side. To refuel, align the right side with the fuel dispenser. The induction lock requires the key to be within proximity of the car, with the engine turned off and the vehicle unlocked, in order to open the fuel tank cap.

Fuel tanks can be categorized into open-type and closed-type. The tank must have sufficient capacity. The suction pipe and return pipe should extend below the minimum liquid level to prevent air suction and splashing that can cause bubbles; the distance between the suction and return pipes should be as far apart as possible, with a partition installed between them; to maintain oil cleanliness, the tank should have a sealed cover with an air filter; the bottom of the tank should be at least 150mm above the ground; special attention should be paid to the anti-corrosion treatment of the tank's inner surface. In hydraulic systems, the fuel tank not only stores oil but also serves to dissipate heat, separate bubbles from the oil, and settle impurities. The tank is equipped with various accessories such as coolers, heaters, air filters, and liquid level gauges.
