| 2 | When driving at high speed (over 100 km/h) during IFS operation, the IFS at the driver's side turns off entirely. | When detecting a vehicle in IFS high-speed mode, the entire light-off logic is being applied to the high beam at the driver's side. (The LED part without vehicle also turns off) → This function is for anti-glare of opposing vehicles by the high beam off responsiveness while driving at high speed and does not mean the headlamp problem. |
| 3 | Problems of parts such as lamp modification/overseas purchase, etc. |
|
| 4 | When pop-up message 'IFS is canceled as the visibility of the camera is limited due to the external environment' is displayed on the instrument cluster. | Securing front visibility of the camera is required: Remove foreign materials on the camera lens or windshield glass |
