ADAS Recalibration: Why a New Windshield Needs It
Lane keeping, automatic braking and adaptive cruise rely on a camera mounted to the glass. Replacing the glass means the camera has to be re-aimed.
What recalibration actually does
The forward-facing camera behind your mirror is aimed to within a fraction of a degree. A new windshield shifts that aim slightly, so the camera must be retaught where the road is.
Static calibration uses printed targets in a controlled bay; dynamic calibration requires a road drive at a steady speed. Many vehicles need both.
Signs it was skipped
Lane-keeping warnings that fire early or late, adaptive cruise that brakes for nothing, or a persistent dashboard warning after a glass job all point to a missed calibration.
