What are the precautions for refueling a sedan?

[LaneMarie]

Precautions for refueling a sedan include: 1. Refuel in the morning or evening to avoid direct sunlight at noon; 2. Add more fresh fuel before long-distance trips; 3. Do not exceed the fuel tank's upper limit; 4. Park, turn off the engine, and cut off the power; 5. No smoking. The correct steps for refueling a sedan are: 1. Slow down and drive into the gas station gently; 2. Turn off the engine before refueling; 3. After filling up, close the fuel nozzle before starting the car; 4. Drive out of the gas station at low speed. The consequences of overfilling the fuel tank are: 1. Excess fuel may overflow and could instantly ignite if exposed to an open flame; 2. Blocking the vent hole can create negative pressure in the fuel tank, leading to poor fuel supply; 3. Gasoline may enter the pipeline, causing the spark plug to malfunction and preventing the vehicle from starting.
