The fuel gauge showing 100km can actually allow you to drive 150-180 kilometers. When the fuel gauge indicates empty, the remaining fuel in the tank is sufficient for at least 50 kilometers, and for larger fuel tanks, it can cover at least 80 kilometers. This is an emergency mode set by manufacturers to ensure drivers can reach a gas station even when the fuel gauge shows empty. During the design phase of vehicles, automakers considered that some drivers might occasionally forget to refuel. Therefore, a fuel warning light is installed on the dashboard, which illuminates when the fuel level drops below a certain threshold, reminding the driver to refuel as soon as possible. Even when the dashboard shows a range of 0 kilometers, the remaining fuel can last longer than expected. Currently, the "reserve range" for various brand vehicles in the market is generally around 50,000 to 60,000 kilometers. Since fuel tank capacities vary among vehicles and fuel consumption differs under various road conditions, the actual remaining range after the fuel warning light comes on will naturally vary. This indicates that when the fuel warning light is on, there are typically 5-10 liters of fuel left in the tank. The residual fuel amount is proportional to the vehicle's engine displacement, primarily to ensure a certain driving distance to reach a gas station. Solutions when the warning light comes on: Control your speed reasonably; reduce vehicle load; avoid using high-power electrical devices; close all windows; choose better road conditions; and try to exit the highway as early as possible.
