What does the flashing green AUTO light on the dashboard mean?

The flashing green AUTO light on the dashboard is the cruise control indicator. Additional information about cruise control is as follows: 1. Introduction: The cruise control system, also known as speed control system, automatic driving system, etc., automatically maintains the vehicle speed as set by the driver without the need to press the accelerator pedal, allowing the vehicle to travel at a constant speed. 2. Principle: Simply put, the cruise control system works by comparing the pulse signal from the speed sensor with the set speed and then issuing commands to the servo mechanism to adjust the throttle opening, either increasing or decreasing it, to ensure the vehicle maintains the preset speed.
I remember encountering a situation where the AUTO indicator on the dashboard was flashing green while driving. This is generally an indication signal when the air conditioning automatic mode is operating. As someone who frequently deals with cars, I've found this usually means the system is automatically adjusting the airflow or cooling effect based on the cabin temperature, especially when the AC is first activated or when there's a significant temperature difference outside. The flashing indicates normal operational status rather than a fault warning. However, if the flashing persists for a long time or is accompanied by the AC not cooling properly, it might indicate minor issues such as unstable temperature sensor signals or the control module initializing. In such cases, I would first pull over to check the AC performance, then refer to the owner's manual for specific causes. Most vehicles are designed this way, so there's no need for excessive concern, but regular maintenance of the AC system can help minimize such disturbances.
