What does the cruise control system indicator light mean?

The cruise control system indicator light being on indicates a fault in the cruise control or improper control of the clutch and throttle. Pressing the cruise control switch button again will turn it off. The cruise control system, also known as the speed control system or autonomous driving system, functions to maintain the vehicle's speed as set by the driver without the need to press the accelerator pedal, allowing the vehicle to travel at a constant speed. The working principle of the cruise control system is as follows: the cruise control component reads the pulse signal from the vehicle speed sensor and compares it with the set speed, then issues commands to the servo mechanism to adjust the throttle opening, either increasing or decreasing it, to ensure the vehicle maintains the preset speed.
The other day while driving on the highway, I suddenly noticed a light come on – it was the speed cruise control system indicator. Normally, this means you've activated cruise control. For example, when I set it to 110 km/h, the light stays steadily green. But if the light remains on without a set speed or turns yellow, it might indicate a system malfunction, like sensors covered by dust or an issue with the brake switch. I'd suggest first checking if you accidentally pressed the set button, then safely pull over, turn off the system, and restart the car. Sometimes on rainy days with lots of dust, sensors are prone to problems, so it's good to clean the sensors near the windshield before driving. This light being on doesn't affect normal driving, but you should investigate promptly to avoid potential cruise control malfunctions causing hazards.
