Hyundai vehicles are equipped with advanced safety and convenience features, including the Adaptive Front Lighting System (AFLS). The AFLS optimizes headlight beam patterns based on steering angle and vehicle speed, enhancing visibility during nighttime driving. However, like any other system, the AFLS can malfunction, triggering a warning light on your dashboard. This article explains the AFLS warning light on Hyundai vehicles, its possible causes, and troubleshooting steps.

Understanding the Hyundai AFLS Warning Light
The AFLS warning light typically illuminates as a yellow or amber symbol on the dashboard. It may resemble a headlight with curved lines indicating the swiveling motion of the beams. When this light comes on, it indicates a potential issue with the AFLS. While the vehicle remains drivable, the adaptive headlight functionality is likely disabled, reducing visibility in corners and curves.
Common Causes of AFLS Light on Hyundai
Several factors can trigger the AFLS warning light on a Hyundai:
- Malfunctioning AFLS Sensor: The system relies on sensors to detect steering angle and vehicle speed. A faulty sensor can provide inaccurate data, causing the system to malfunction and activate the warning light.
- Wiring Issues: Damaged or corroded wiring connecting the AFLS components can disrupt communication and trigger the warning light.
- Bulb Failure: Although less common, a burned-out headlight bulb can sometimes cause the AFLS light to illuminate. The system may detect an imbalance in light output and trigger the warning.
- Low System Voltage: Insufficient voltage from the battery can affect the operation of the AFLS and activate the warning light.
- Software Glitch: In rare cases, a software problem within the vehicle’s computer system can lead to the AFLS warning light appearing.
Troubleshooting the AFLS Warning Light
If the AFLS warning light comes on in your Hyundai, consider these troubleshooting steps:
- Check Headlight Bulbs: Inspect both headlights for any burned-out bulbs. Replace any faulty bulbs and see if the warning light resets.
- Inspect Wiring: Visually examine the wiring connections to the AFLS components for any signs of damage or corrosion. If any issues are found, repair or replace the wiring.
- Check Battery Voltage: Ensure the battery is properly charged and providing sufficient voltage. A low battery can cause various electrical issues, including problems with the AFLS.
- Consult a Professional: If the basic troubleshooting steps don’t resolve the issue, it’s recommended to consult a qualified Hyundai mechanic or dealership. They have the diagnostic tools and expertise to pinpoint the exact cause of the problem and perform necessary repairs. A professional mechanic can access the vehicle’s computer system to read error codes related to the AFLS, providing valuable insights into the issue.
Conclusion
The AFLS warning light on a Hyundai indicates a potential issue with the Adaptive Front Lighting System. While not an immediate safety concern, addressing the underlying cause is crucial to restore the system’s functionality and enhance nighttime visibility. By understanding the potential causes and troubleshooting steps, you can effectively address the AFLS warning light and maintain optimal driving safety. If the problem persists, seeking professional assistance is recommended to ensure a proper diagnosis and repair.
