What does the 'a' symbol in the car mean?

[DelRosalie]

a symbol is the automatic start-stop indicator. There is an automatic start-stop indicator light on the car's dashboard, as well as an automatic start-stop switch. Both the indicator light and the switch have the letter 'a'. Below is relevant information: 1. Meaning of the automatic start-stop indicator light: Many cars today are equipped with an automatic start-stop function, which can reduce exhaust emissions and save fuel. Cars with this feature have an indicator light on the dashboard. If the automatic start-stop system is functioning properly, the indicator light is usually green. If the system is not working correctly, the indicator light is typically yellow or red. 2. Automatic start-stop does not harm the car: Many car owners worry that the automatic start-stop function may damage the car, but there is no need for concern. The automatic start-stop function only activates when the engine coolant reaches normal operating temperature and the battery has sufficient charge. The primary purpose of the automatic start-stop system is not just to save fuel but to reduce exhaust emissions. With environmental concerns becoming increasingly prominent, major automakers are adopting various measures to lower vehicle emissions.
