Safety Warning
Skipping ADAS calibration after windshield replacement is dangerous. Automatic emergency braking and lane-keep assist can malfunction without it.
What Is ADAS?
ADAS stands for Advanced Driver Assistance Systems — the safety technologies in modern vehicles including Automatic Emergency Braking, Lane Departure Warning, Adaptive Cruise Control, Forward Collision Warning, and Pedestrian Detection. Most rely on a forward-facing camera mounted to the windshield.
What Is ADAS Calibration?
ADAS calibration re-aligns the forward-facing camera to factory specifications after windshield replacement. Even a shift of a fraction of a millimeter causes the system to misjudge lane positions by several feet or fail to detect hazards at the correct distance.
