What is the AFS OFF switch?

AFS OFF refers to the flashing indicator light that appears when there is a malfunction in the automatic adjustment system of the headlight beam direction. Below is relevant information about AFS OFF: Definition of AFS OFF: The Adaptive Front-lighting System (AFS) adjusts the direction of the headlight beam according to current driving conditions. This system moves the headlight beam left or right based on vehicle speed and steering wheel angle, working in conjunction with the automatic headlight beam direction adjustment system to enhance visibility during intersections and turns. Components: Sensors, ECU, headlight control system, and headlights. The vehicle speed sensor and steering wheel angle sensor continuously transmit detected signals to the ECU. The ECU processes these signals, makes judgments based on the processed data, and outputs headlight angle commands to rotate the headlights by the corresponding angle.
The AFSOFF switch is a button used to control the AFS (Adaptive Front-lighting System) function. Simply put, it's the switch for the cornering light assist feature. When you turn on AFS, the headlights will automatically adjust their direction based on the steering wheel angle and vehicle speed. For example, when turning, the lights will illuminate the inner side of the curve in advance. However, on bumpy roads or during rainy or foggy conditions, the system might misjudge and cause the lights to flicker. In such cases, pressing AFSOFF can temporarily disable the automatic steering function, keeping the headlights fixed forward. I often turn it off when driving on mountain roads, as the narrow paths require stable lighting instead.
