What to Do When the Yellow Fuel Light Comes On

Driving tips after the fuel gauge yellow light comes on: Turn off electrical devices in the car. Although it's a gasoline-powered vehicle, when high-power electrical devices are used, the car's alternator also increases its power output. In a low-fuel state, turning off high-power electrical devices can help conserve fuel. Close the car windows and turn off the air conditioning. The air conditioning is a major fuel consumer, and driving with windows or sunroof open increases aerodynamic drag, leading to higher fuel consumption. Keeping windows closed reduces drag and lowers fuel consumption. Maintain a steady speed within the economical speed range. The economical speed varies depending on the engine displacement. Generally, for 1.2L-1.6L engines, it's around 70km/h; for 1.6L-2.0L, about 100km/h; and for displacements ≥2.0L, approximately 120km/h. Driving within this range ensures the engine operates at its most efficient level, minimizing fuel consumption and allowing you to travel farther even with low fuel. Reduce vehicle weight. Heavier loads lead to higher fuel consumption. In a low-fuel situation, lighten the load by removing cargo or reducing passengers to make it easier to reach the gas station. Daily precautions: When you notice the fuel level is low during daily driving, head to a gas station as soon as possible to avoid prolonged low-fuel driving. The fuel pump in the tank relies on gasoline for cooling. If the fuel level remains too low for an extended period, the pump may overheat and malfunction.
I just encountered this situation a couple of days ago when the fuel gauge light suddenly turned yellow on the highway. The key is not to panic—first, turn on the hazard lights and slow down to move to the far-right lane. If you see a gas station sign nearby, don’t hesitate and head straight there. If the navigation shows the nearest one is still 5 kilometers away, don’t push your luck. If you completely break down and have to stop by the roadside, set up the warning triangle and move behind the guardrail, then contact your insurance company—they usually offer free fuel delivery services, or you can ask a friend to bring some spare gasoline for emergencies. When this light comes on, you generally have about 50 kilometers left, but it’s best to refuel before the tank drops to one-tenth. Make it a habit not to wait until it’s almost empty to refuel, as it can damage the fuel pump.
