What does the AFS warning light indicate?

AFS stands for the Adaptive Front-lighting System warning light. Here are the specific details about the adaptive front-lighting system: 1. Function: The Adaptive Front-lighting System (AFS) adjusts the direction of the headlight beams according to current driving conditions. The system moves the headlight beams left or right based on vehicle speed and steering wheel angle, working in conjunction with the automatic headlight beam adjustment system to improve visibility at intersections and during turns. 2. Turning off the AFS system: The system activates when the vehicle speed exceeds 10 km/h. It operates within the maximum range of the steering wheel angle. If you do not wish to activate the system, press the "AFS OFF" button to turn it off. To turn it back on, press the button again. When the system is off, the "AFS OFF" indicator on the instrument cluster will illuminate. If there is a malfunction in the system, the "AFS OFF" indicator on the instrument cluster will flash.
The other day when I was repairing a car, I encountered a vehicle with the AFS light on, which indicates a fault in the Adaptive Front-lighting System. This system is quite advanced—it automatically adjusts the headlight angle during turns to improve nighttime visibility. Common issues include interrupted signals from the steering sensor, incorrect data from the speed sensor, or simply a stuck headlight leveling motor. Once, while working on a car, I found that oxidized wiring connectors after rain caused poor contact. If the motor is broken, it's a real hassle—you'd have to replace the entire adjustment mechanism. Don't ignore this light, especially when driving at night—it's particularly dangerous. If the headlights don't turn with the steering wheel, blind spots can increase. I recommend going to a 4S shop first to connect to the computer and read the fault codes to pinpoint the issue before making repairs.
