What does the yellow OFF light on the dashboard mean?

[OHarrison]

The yellow OFF light on the dashboard indicates that the auto start-stop function is turned off. The engine auto start-stop function is enabled by default. To disable the engine auto start-stop function, you need to press the auto start-stop button again. When the engine auto start-stop function is turned off, a small yellow light will illuminate on the button. If the engine auto start-stop function is activated, the yellow light on the button will turn off. Engine auto start-stop automatically shuts off the engine when the vehicle comes to a temporary stop (such as at a red light). 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 systems that control engine start and stop. It works by equipping a traditional engine with an enhanced motor that has an idle start-stop function, allowing the engine to completely shut off when the vehicle meets the conditions for idling. When the vehicle needs to start moving again, the idle start-stop motor system quickly responds to the driver's start command, rapidly restarting the engine for seamless operation, thereby significantly reducing fuel consumption and exhaust emissions. How the start-stop system works: When the vehicle stops moving due to traffic congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this point, the system automatically detects that 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. Once these three conditions are met, the engine automatically stops. When the traffic light turns green, the driver presses the clutch, and the "start-stop device" can be activated immediately, quickly restarting the engine.
