What does A mean?

Auto start-stop (symbol: A) is a feature found in many modern vehicles that automatically shuts off the engine when the car is stopped and restarts it when the driver takes their foot off the brake or engages the accelerator. This helps to save fuel and emissions, especially in stop-and-go traffic.
The auto start-stop symbol in vehicles is a circle with an A inside and a clockwise arrow. The A stands for Auto and the arrow signifies the stopping and restarting of the engine. This symbol is typically located on the control panel or dashboard of a vehicle, near the button or switch that activates or deactivates the auto start-stop function.
