ADAS Calibration, Explained Plainly

Why a new windshield means a calibration check

The camera was aimed through your old windshield, in its exact position. A replacement windshield — even a perfect one — sits a fraction differently, and the camera comes off and goes back on during the job. A fraction is enough: a camera aimed slightly wrong reads lane lines slightly wrong, at exactly the moments the system exists for. Vehicle makers therefore require calibration after windshield replacement on equipped vehicles.

Static and dynamic calibration

Dynamic calibration is done on the road: the vehicle is driven at set speeds on well-marked roads while the system relearns. Static calibration is done in a shop with targets placed at measured distances on a level floor. Some vehicles need one, some the other, some both — the maker's procedure for your exact model decides, and a proper shop follows it rather than choosing the convenient one.

Questions to ask any glass shop

Does my vehicle require calibration after this replacement? Who performs it, and with what procedure? Will I get confirmation it passed? If a shop replacing a camera-equipped windshield has never heard of calibration, that is your answer about the shop. Start with the Windshield Replacement hub for the full job, start to finish.
