What does it mean when the AFS warning light is on?

AFS warning light being on indicates that the adaptive cruise headlights are turned off. If it's not manually turned off by the driver, then it means there's a malfunction in the adaptive cruise headlights, and the specific cause should be checked promptly. The adaptive cruise system is an intelligent automatic control system primarily used to maintain distance from the vehicle ahead and adjust the car's speed during long-distance driving, thereby reducing driver fatigue. Precautions when using the adaptive cruise system include: 1. Avoid using it in rain, snow, fog, or poor road conditions to prevent safety hazards; 2. Regularly inspect the vehicle's sensing radar and cameras to prevent malfunctions that could render the adaptive cruise system ineffective.
I've seen the AFS warning light come on several times, which usually indicates an issue with the adaptive headlight system's sensor. The sensor is located near the headlights and is responsible for detecting your steering angle and vehicle speed to adjust the light direction accordingly. If it gets dirty or damaged, the light will illuminate to signal a fault. Sometimes it's caused by short circuits due to aging wiring or loose connections, or there might be an issue with the headlight module itself. I recommend first checking if the sensor is covered by mud or snow—give it a simple clean to see if the light turns off. If the light remains on, don't take it lightly; this system improves visibility during nighttime turns, and if it fails, you might struggle to see clearly around curves, increasing the risk of an accident. Head to a 4S shop immediately to have the fault codes read with a diagnostic tool—they have professional equipment to pinpoint the issue. Avoid DIY repairs, as you might damage other components. When washing your car, pay attention to protecting the sensor area to minimize such problems.
