What does the car display when it runs out of fuel?

When the car runs out of fuel, the fuel indicator light will illuminate to alert the driver. The amount of remaining fuel is monitored by a float sensor in the fuel tank. Once the sensor detects the fuel level, it sends this signal to the ECU, which then comprehensively analyzes and relays the information to the dashboard. If the fuel level is too low, the fuel indicator light will illuminate. Fuel indicators come in two types: needle-style and electronic-style, with the letters F and E marked at each end. Pointing to F indicates the tank is full, pointing to E means the tank is empty, and pointing to the middle indicates the tank is half full. Generally, after the indicator light warns, the vehicle can still travel 50 to 90 kilometers under normal road conditions. However, continuing to drive beyond this point is not recommended as it may affect the fuel pump's cooling, so it is advisable to avoid such driving unless under special circumstances.
