What does the car's A symbol mean?

[BrantleyLee]

The car's A symbol represents the auto start-stop function. There is an auto start-stop indicator light on the instrument panel inside the car, as well as an auto start-stop switch. Both the indicator light and the switch feature the letter A. Vehicles equipped with auto start-stop have an indicator light on the instrument panel. If the auto start-stop system is functioning properly, the indicator light is green. If the system is not working correctly, the light turns yellow or red. When the battery charge is too low, the auto start-stop system cannot operate normally, but after driving for a while, the system will resume normal operation. The start-stop system pauses the engine when the vehicle comes to a stop (not in park mode), instead of maintaining traditional idle speed. During this pause, the engine's lubricating oil continues to circulate, ensuring the engine remains lubricated.
