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

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.
My Haval H6 also had the issue of the dashboard displaying an 'A' before, and I talked about it at my friend's auto repair shop. This icon represents the status of the auto start-stop function, which simply means the car automatically shuts off to save fuel when waiting at a red light. When the 'A' light is green, it indicates the system is operating normally. If it flashes yellow, you need to pay attention—it could mean the battery voltage is insufficient or the hill descent control mode is activated. Once, my car started at minus ten degrees Celsius, and the 'A' light stayed yellow. After checking, I found the battery was aging and couldn’t hold enough charge. It only returned to normal after driving for half an hour on the highway to recharge. Now, I always have the battery health checked during every maintenance service. This light actually reminds us to pay attention to the vehicle's condition.
