Windshield Glass
WARNING: This page is about a different car, the 2022 Subaru WRX. However, it is still accessible from the selected car via links, so may be relevant.
Check the windshield glass. In the angle of view area of the high beam assist camera, there must be no oil film, dirt, fogging or scratch that obstructs the forward visibility of the high beam assist camera. Clean the windshield glass if oil film, dirt or fogging is found on the glass. When the glass of the high beam assist camera is not normal due to scratches in the angle of view area, the high beam assist performance may be affected and the function may not operate properly.
