What does the yellow light for start-stop mean?

[DiGriffin]

If the auto start-stop light is continuously yellow, it indicates that the auto start-stop function cannot operate normally. This may be due to low battery power affecting the system's ability to function properly. Definition of auto start-stop: Engine auto start-stop automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) during driving. When it's time to move forward again, the system automatically restarts the engine. Its English name is STOP-START, abbreviated as STT. The STT intelligent fuel-saving system is a set of controls for engine start and stop. How the start-stop system works: When the vehicle stops moving due to congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. The Start-Stop system automatically detects that the engine is idling, no gear is engaged, and the wheel speed sensors of the anti-lock system show zero.
