Modern vehicles rely heavily on cameras and sensors to support driver assistance features like lane keeping, collision alerts, and adaptive cruise control. When a windshield is replaced or sensors shift even slightly, these systems may lose accuracy. That is why calibration is a critical step after glass repair or replacement. Professional technicians use specialized tools and software to realign the cameras and verify sensor positioning. In many repair shops, Windshield ADAS calibration is performed to ensure the cameras correctly read road markings, vehicles, and obstacles. Proper calibration improves safety, restores system reliability, and helps advanced driver assistance technologies perform as designed.
