What is the fuel warning light on a Subaru?
The fuel warning light on a Subaru is an important indicator that alerts the driver when the vehicle's fuel level is running low. This light serves as a crucial reminder to refuel the car before it runs out of gas, preventing potential breakdowns or inconveniences.
What is the Fuel Warning Light?
The fuel warning light, also known as the low fuel light, is a dashboard indicator that illuminates when the fuel tank level drops below a certain threshold, typically around 1 to 2 gallons of fuel remaining. This light is designed to provide a clear visual cue to the driver, prompting them to refuel the vehicle as soon as possible.
How Does the Fuel Warning Light Work?
The fuel warning light is connected to a fuel level sensor located in the fuel tank. This sensor continuously monitors the amount of fuel in the tank and sends this information to the vehicle's computer. When the fuel level drops below the predetermined threshold, the computer triggers the fuel warning light to illuminate on the dashboard, alerting the driver to the low fuel condition.
Reasons for the Fuel Warning Light
The fuel warning light can illuminate for a few different reasons:
- Low Fuel Level: The most common reason for the fuel warning light to turn on is when the fuel tank level drops below the predetermined threshold, typically around 1 to 2 gallons of fuel remaining.
- Fuel Sensor Malfunction: If the fuel level sensor in the tank is malfunctioning, it may send inaccurate information to the vehicle's computer, causing the fuel warning light to illuminate even when the tank is not low.
- Wiring Issues: Problems with the wiring or electrical connections between the fuel level sensor and the vehicle's computer can also trigger the fuel warning light.
If the fuel warning light illuminates and the driver is unsure of the reason, it's best to have the vehicle inspected by a qualified mechanic to diagnose and address the underlying issue.
Responding to the Fuel Warning Light
When the fuel warning light illuminates, the driver should take the following steps:
- Refuel the Vehicle: The primary action is to refuel the vehicle as soon as possible, ideally before the tank runs completely dry. Continuing to drive with the fuel warning light on can lead to the engine stalling and the vehicle becoming stranded.
- Check for Fuel Sensor Issues: If the fuel warning light remains on after refueling, it may indicate a problem with the fuel level sensor or the vehicle's electrical system. In this case, the driver should have the vehicle inspected by a mechanic.
- Avoid Running Out of Fuel: Running out of fuel can cause damage to the fuel pump and other components, leading to costly repairs. It's important to refuel the vehicle before the tank is completely empty.
By understanding the purpose and function of the fuel warning light, Subaru owners can proactively manage their vehicle's fuel levels and avoid the inconvenience and potential consequences of running out of gas.

What causes fuel light to come on?
On the other hand, the fuel gauge itself could be malfunctioning. A blocked fuel-tank vent could also cause the gas light to come on, as a warning that fuel vapors are not properly venting, which doesn't necessarily have anything to do with fuel level, and can still cause a light to come on.
How long do I have after my fuel light comes on?

What does the fuel light look like?
In most new and used models, the “Low Fuel” light signal is either designated by flashing text or a symbol of a gas pump.
