Why is the fuel warning light yellow?

[OJeffrey]

When the fuel warning light turns yellow, it indicates that the vehicle needs to be refueled. Below is an introduction to the related content: 1. Remaining fuel: When the low fuel warning is triggered, the remaining fuel in the tank is approximately 5 liters. However, this value may vary depending on the vehicle model and manufacturer. For example, in general mid-sized cars, the remaining fuel is typically around 9 liters to ensure driving capability, while larger vehicles may have even more remaining fuel. 2. Function: During the design phase of vehicles, some manufacturers take full consideration of the fuel tank. To prevent the car from suddenly stalling due to running out of fuel while driving, they implement a pre-warning function that alerts the driver when fuel levels are insufficient.
