What Is ADAS Calibration?

ADAS stands for Advanced Driver-Assistance Systems — the collection of technologies that includes lane-keeping assist, automatic emergency braking, adaptive cruise control, and forward-collision warnings. Many of these systems rely on a small camera mounted near the top of the windshield, right around the rearview mirror.

That camera is aimed with extremely fine tolerances — fractions of a degree matter. When a windshield is removed and a new one installed, even a careful installation can shift the camera's precise alignment slightly. Calibration realigns the camera so it continues to read lane markings, vehicles, and obstacles accurately.

Static calibration is performed in a shop using specially positioned printed targets and measured distances. Dynamic calibration involves driving the vehicle under specific conditions — often a certain speed range on a road with clear lane markings — so the system calibrates itself. Some vehicles require both.

If your vehicle has a small camera housing near the rearview mirror, it likely has ADAS features that require calibration after windshield replacement. If you're not sure, tell us your year, make, and model and we'll help confirm it.
