What does the yellow light below the fuel gauge mean?

[DiRobert]

The illumination of the yellow light below the fuel gauge indicates that the remaining fuel level is low. At this point, it is advisable to refuel promptly. However, it is best to refuel before the yellow light comes on to protect the fuel pump. Prolonged low fuel levels can cause the fuel pump to overheat, and the pump is also prone to sucking up debris from the bottom of the fuel tank, leading to clogging. The distance a car can travel after the fuel gauge light comes on varies depending on the fuel tank capacity of different vehicle models and driving conditions. Typically, when the yellow light on the fuel gauge illuminates, there is still more than 12.5% of fuel remaining in the tank, approximately 8 liters. For an average family car, this usually allows for a range of about 80-100 kilometers. When the yellow light comes on, drivers should control their speed appropriately on the way to the next gas station. They should turn off unnecessary electrical devices in the car, such as the air conditioning and music, and slightly close the windows to reduce wind resistance. It is also recommended to drive on smooth road sections and plan the route carefully to avoid taking wrong turns and consuming extra fuel.
