How to resolve the AFS OFF light being on?
3 Answers
AFS stands for Adaptive Front-lighting System. When the AFS OFF light is on, it indicates that the system is turned off. It is recommended to visit a 4S shop to diagnose the cause and perform repairs. Below is relevant information about AFS: 1. Function of AFS: AFS is an Adaptive Front-lighting System that dynamically adjusts the headlights based on the car's steering wheel angle, vehicle yaw rate, and driving speed to adapt to the current steering angle, ensuring the light direction aligns with the vehicle's current driving direction. This provides optimal illumination of the road ahead and maximum visibility for the driver. The system automatically adjusts the headlight deflection according to driving speed and steering angle to illuminate "unreached" areas in advance, offering comprehensive safety lighting, thereby significantly enhancing driving safety in the dark. On roads with no (or weak) lighting or multiple curves, it expands the driver's field of vision and can alert oncoming vehicles in advance. 2. Types of AFS: The Adaptive Front-lighting System is mainly divided into static systems and dynamic systems.
I've been driving this car with AFS for a while now. The most common situation when the light comes on is that the system automatically turns off, such as when the weather is bad or during fog when the sensors can't see the road clearly and deactivate. That time I was driving in heavy fog, the lights automatically went off, but luckily I was alert. First, check if there's an AFS button inside the car that might have been accidentally pressed; or go into the vehicle settings menu to reset it. Restarting the car sometimes works too. If the sensors are dusty, clean the camera area thoroughly—I usually use a soft cloth. If the light stays on constantly, don't ignore it—this system helps with cornering illumination, and turning it off can be dangerous when making turns at night. Get it checked at a professional shop as soon as possible to avoid deeper issues with the bulb or module. Safety always comes first—don't skimp on small fixes that could lead to bigger problems.
As a car owner, I'm quite concerned about this issue. When the AFS Off light is on, it means the system is deactivated, possibly due to accidental button pressing or sensor malfunction. Last time I encountered this, I found dirt on the windshield affecting the camera detection. Check if the interior switch is in the ON position and try restarting the engine. Also, pay attention to environmental factors - heavy rain or dust can easily trigger system shutdown. Don't worry too much about complexity; cleaning the sensors yourself often solves most cases. This system assists with visibility safety, especially by illuminating wider areas during turns. Long-term neglect may lead to bulb aging or other chain failures. I'll address it promptly to ensure safer night driving.
