How to Read the Fuel Gauge on a Jetta?
2 Answers
On the fuel gauge, 'F' stands for full, using the first letter of 'full', and 'E' means enough. Even when the fuel gauge points to 'E', there is still a small amount of fuel left in the tank to support the driver in reaching a gas station. The fuel gauge displays the fuel level through a float in the fuel tank connected to a metal rod, a principle similar to the water tank in a bathroom toilet. Here are some related introductions about the car fuel gauge: 1. Introduction one: The position of the float on the surface of the fuel in the tank changes, which is transmitted via the metal rod to alter its position on a variable resistor. This variable resistor is then connected to the car's fuel gauge, and the movement of the fuel gauge pointer is controlled by the amount of current passing through the variable resistor. 2. Introduction two: The car fuel gauge is highly functional and advanced. It can display the real-time fuel level in the car's tank, accurately informing the owner about the fuel consumption and the remaining fuel storage. The owner can also make judgments based on the fuel gauge display, such as whether to refuel or how many more miles can be driven. 3. Introduction three: The fuel gauge acts like a warning light for the car's life. It is an indicator on the engine that displays the fuel level, either with a pointer or digitally. Therefore, current car fuel gauges are mainly divided into two types: digital display fuel gauges and pointer fuel display gauges.
Having driven for many years, I'm quite familiar with reading the Jetta's fuel gauge. After starting the engine, there's a small fuel tank icon on the left side of the dashboard, and the needle gradually moves to indicate the fuel level: E means it's almost empty and you must refuel immediately, while F represents a full tank. In practice, I make it a habit to refuel when the needle drops below the quarter mark to avoid damaging the fuel pump or risking a breakdown due to low fuel. Combined with the remaining mileage display on the Jetta's dashboard, I can estimate how far I can still drive, which is useful for both city commutes and long trips. For example, when the needle is in the middle and the fuel consumption is around 7L/100km, I can roughly drive another 200 kilometers. It's important to develop the habit of checking before departure; when the low fuel warning light comes on, don't delay refueling, as it could affect safety. Regular maintenance can prevent inaccurate fuel gauge readings, saving a lot of trouble.
