When the fuel gauge shows 0 km and the warning light comes on, it is just a reminder to refuel, as there is still some fuel left in the tank. Generally, most household cars can still run for at least 20-30 kilometers without any issues. However, the exact distance depends on the specific model, as each car has a different fuel tank size, fuel consumption, and settings. Below are some relevant details: Warning Light: When the fuel gauge warning light comes on, a typical household car usually has about 5 liters of fuel remaining. The exact remaining fuel quantity can be found in the vehicle's user manual. For example, a Passat will have about 9 liters of fuel left when the light comes on, as it is a mid-size car with a larger fuel tank. Service Areas: The driver's skills, road conditions, and weather all affect fuel consumption. If the fuel warning light comes on while driving on a highway, try to maintain a steady speed and drive on the right side. It is also recommended to turn off the air conditioning to maximize fuel efficiency. According to national highway regulations, there is a service area approximately every 57 kilometers. Driving on highways can significantly save fuel, and most vehicles can make it to the next gas station.

Last time I drove my Volkswagen Passat, I panicked when the fuel gauge showed 0 km. I gritted my teeth and drove off the highway to find a gas station, and ended up driving 28 km before refueling. Later, I checked the manual and learned that when Volkswagen designs this 0 km display, there are actually 5-8 liters of fuel left in the tank. Based on a fuel consumption of 8 liters per 100 km, it can last for 30-50 km. But don't follow my example! Since that incident, I refuel when the gauge shows 1/4 left. After all, breaking down on the road and calling a tow truck is more troublesome, and it might even damage the fuel pump.

After driving Volkswagen for so many years, I've found that how far you can go after the fuel gauge hits 0 km depends on the situation. My Tiguan only lasted 25 km in stop-and-go city traffic, but managed over 40 km at a steady 90 km/h on the highway. Engineers actually reserve enough backup fuel for 30-50 km, but this distance includes time to find a gas station. I recommend checking nearby gas stations on your phone in advance, avoiding uphill routes, and turning off the AC to save fuel. However, the safest approach is to refuel when the yellow warning light comes on—don't push your luck.

Don't panic when the fuel gauge hits 0 km, your Volkswagen can still go a bit further. First, turn off the AC and audio to reduce load, maintaining a steady speed of 60-80 km/h is most fuel-efficient. Use your phone's navigation to find the nearest gas station – within 30 km is generally safe. If the car stalls midway, be sure to turn on hazard lights and pull over, never stop on a curve. However, remember that frequently running on empty will shorten the fuel pump's lifespan – you should refuel when the warning light comes on.
