What does the auto switch in a car indicate?

[OAngela]

The auto switch in a car indicates: 1. AUTO on the window: After activation, pressing the window switch once will automatically open or close the window without the need to hold the button; 2. AUTO on the air conditioning: Automatic mode, this button is typically used in car air conditioning systems, referring to the automatic air conditioning mode, as opposed to the manual mode; 3. Engine start-stop system, which is an energy-saving mode equipped in some vehicles. When the car encounters a red light or needs to stop during driving, the engine will pause operation after the driver brakes to a complete stop, putting the engine in a resting state. This feature helps save fuel consumption during temporary stops or while waiting at traffic lights.
