What does the display of 'A' on the Haval H6 dashboard mean?

[MacJudah]

The display of 'A' on the Haval H6 dashboard indicates that the auto start-stop system is not functioning. Auto Start-Stop: The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (such as at a red light) and restarts it when it's time to move forward again. Auto Start-Stop Principle: The working principle of the start-stop system is that when the vehicle stops moving due to traffic congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. The Start/Stop system automatically checks if the engine is idling and not in gear, the wheel speed sensors of the anti-lock system show zero, and the electronic battery sensor indicates there is enough energy for the next start. When these three conditions are met, the engine automatically stops running.
