What does it indicate when the gas symbol light is lit on a dashboard?

When the gas symbol light is illuminated on a dashboard, it indicates that the vehicle's gas tank is empty or nearing empty. This light serves as a warning to the driver that the fuel level has fallen below a certain threshold, prompting the need to refuel soon to avoid running out of gas. Understanding this warning is crucial, as failing to address it can lead to the vehicle stalling or being unable to start again until fuel is added. Driving with low fuel can also cause potential damage to the fuel system, as the pump may overheat without sufficient fuel to keep it cool. Being attentive to dashboard warnings, especially regarding fuel levels, is an essential part of vehicle maintenance and operation.
