How many kilometers can a sedan run when the fuel light is on?

When the fuel light comes on in a sedan, the remaining fuel is approximately 7 liters in front-wheel-drive models and about 8.5 liters in four-wheel-drive models. Generally, it can run for about 40 kilometers, but this situation should be avoided as prolonged operation in this state can harm the vehicle. Unless absolutely necessary, it's best not to take the risk. Below is some relevant information about the fuel indicator light: 1. After the fuel indicator light comes on, whether it's the remaining mileage displayed on the dashboard or the mileage calculated based on experience, it can only serve as a reference. 2. The fuel indicator light warning may be inaccurate due to fuel sloshing in the tank on bumpy roads. Additionally, vehicle fuel consumption is not a fixed parameter and is influenced by various factors. At this point, finding the nearest gas station is the most important thing.
When the fuel light comes on, I've seen too many similar situations over years of driving. Typically, you can still drive about 50 to 80 kilometers, but this is highly unreliable. Factors affecting the distance include your driving style—for example, maintaining a steady speed on the highway might allow you to go farther, but frequent braking or accelerating in city traffic will reduce it significantly. Another key point is the safety risk: low fuel levels can damage the fuel pump since the fuel acts as a coolant. If you break down in a remote area, the towing fees can be high and cause delays. My advice is to refuel at the next opportunity as soon as the light comes on, preferably within 30 kilometers. Make it a habit to refuel before the light turns on and keep the tank at least half full. The manual provides specific estimates for remaining fuel—check your car’s details, as this varies greatly by brand. German cars might be more conservative, while Japanese cars may perform slightly better. In short, don’t test the limits—safe driving comes first.
From a technical perspective, when the fuel warning light illuminates, the remaining fuel is approximately 10-15%, typically supporting a driving range between 50 to 80 kilometers. This depends on multiple variables: the vehicle's engine efficiency, current fuel consumption (factors like air conditioning usage or increased load can raise consumption), and road conditions such as hilly or winding routes. The sensor triggers the light based on a preset threshold, but the system has inherent inaccuracies—older vehicles may show less precision. Some models display estimated remaining kilometers on the dashboard (e.g., Volkswagen's 90km warning), though this shouldn't be fully relied upon as aggressive driving will reduce the actual range. Note: Fuel levels are already low before the light activates, so refueling early is advisable to avoid fuel pump damage. Maintaining an economical driving mode—such as smooth acceleration and using cruise control—can slightly extend the range. Understanding these factors helps better plan refueling timing.
