ADAS calibration after a windshield replacement
Updated July 21, 2026
Short answer
If your car has a camera mounted behind the windshield, the vehicle procedure may require initialization or recalibration after the glass is replaced. We check the procedure for your exact vehicle. When recalibration is required, we handle it in-house with our equipment and controlled bay.
What ADAS is, in plain terms
ADAS stands for Advanced Driver Assistance Systems. On many cars from roughly 2018 on, a small camera behind the windshield watches the road for lane-keeping, forward-collision and automatic braking, and adaptive cruise. It is aimed through the glass, so when the glass comes out and a new one goes in, the camera's aim shifts slightly.
Why it has to be recalibrated
A camera that is off by a fraction of a degree can read a lane or a car ahead incorrectly. There is usually no dashboard warning that it is miscalibrated, which is what makes skipping it dangerous. Vehicle makers and the Auto Glass Safety Council treat recalibration after a windshield replacement as required, not optional, whenever the procedure calls for it. It is a safety step, not an upsell.
Which vehicles need a calibration check?
Model year alone is not enough. The installed camera and safety package matter. Our vehicle and feature guide explains the clues, then we confirm the exact requirement from the vehicle procedure.
Static vs dynamic calibration
Static calibration uses measured targets while the vehicle stays in place. Dynamic calibration uses a prescribed road drive. Some vehicles need one method and some need both. The manufacturer procedure for the exact vehicle decides.
How we handle it
We do it in-house. We check whether your vehicle has a windshield camera before the job, find the manufacturer procedure, and handle required calibration with our equipment and a level, controlled bay when static calibration calls for it. Ask your insurer or TPA whether the policy covers that work as part of the glass claim.
Questions about this guide
- How do I know if my car needs calibration?
- If it has lane-keep, automatic braking, or a camera visible behind the top of the windshield, it likely does. Tell us your year, make, and model and we will confirm.
- Is calibration legally required?
- There is no specific law, but the vehicle maker's repair procedure requires it, and reputable shops treat it as mandatory for safety.
- Do you calibrate in-house or send it out?
- In-house. We have our own recalibration equipment and a controlled bay for static calibration. We check and follow the procedure for the exact vehicle.
