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.

The yellow fuel gauge light means it's almost empty! When I encountered this, I immediately turned off the AC to reduce fuel consumption and used my phone to navigate to the nearest gas station, only to find the closest one was near the next exit. If you really can't make it, don't push it—running completely out of fuel is especially bad for the engine and can even damage the fuel pump. When parking on the roadside, remember to face the front of the car toward the guardrail to avoid the risk of being rear-ended. Calling your insurance company for fuel delivery is the fastest solution; if you don't have that service, Didi chauffeur can also deliver bottled gasoline. Make it a habit to glance at the fuel gauge when you get in the car—I always plan my next refueling spot when the tank is half full.

With ten years of driving experience, I know that when the fuel light flashes yellow, it's time to act. Immediately turn off power-consuming devices like the AC and audio system, then gradually slow down and pull over to check for nearby gas stations. It's best to find one within three kilometers according to the navigation; don't risk it if it's over five kilometers. After a complete stop, set up a warning sign, move to a safe area, and contact roadside assistance. Actually, when the fuel light comes on, you can still drive at least 50 kilometers. Once, I pushed it to get home, but the next day the fuel pump made strange noises, costing over 800 in repairs. It's wise to set a refueling reminder, like topping up when the tank reaches a quarter full.
