ADAS Calibration in Ann Arbor, MI

What is ADAS calibration and when do I need it?


ADAS calibration is the process of realigning the cameras and sensors that power your vehicle's safety features, like lane departure warning, adaptive cruise control, and automatic braking, so they see the road accurately again. You need it after a windshield replacement, a wheel alignment, or any accident that could have shifted a camera or sensor, even slightly. A2 Auto Glass performs this calibration in house in Ann Arbor and can typically complete it the same day

as your other service.

What ADAS Calibration Actually Does

Modern vehicles rely on cameras and sensors, often mounted behind the windshield, in the bumper, or near the side mirrors, to run Advanced Driver Assistance Systems (ADAS) like:

• Lane departure warning and lane keeping assist

• Adaptive cruise control

• Automatic emergency braking • Blind spot detection

• Forward collision warning These systems only work correctly if the camera or sensor is aimed with precision.


Even a fraction of a degree off can mean the system misreads distance, lane position, or an obstacle in the road.

When You'll Need Recalibration

 • After a windshield replacement. Removing and reinstalling the windshield shifts the camera mounted to it, even with careful work.

• After a wheel alignment. Changing your vehicle's suspension angles changes how the vehicle drives in relation to what the cameras and sensors expect, which can throw them out of calibration.

• After an accident. Any impact, even a minor one, can shift a camera or sensor's position or damage it outright. If any of these apply to your vehicle, driving without recalibration means your safety systems may not respond the way they're supposed to, or may not activate at all.

adas calibration FAQs in ann arbor, MI

  • Do I need calibration after every windshield replacement?

    Only if your vehicle has a camera or sensor mounted on or near the windshield for ADAS features. Most

    vehicles from the last several years do. We can confirm whether yours needs it.

  • Does insurance cover ADAS calibration?

    When calibration is needed because of a windshield replacement, A2 Auto Glass can bill both the glass and the calibration to your insurance under comprehensive coverage. We handle that paperwork directly.

  • How long does ADAS calibration take?

    Calibration is typically completed the same day, often in the same visit as the windshield replacement, wheel alignment, or accident repair that made it necessary.

  • Can you calibrate any make or model?

    We work with nearly any foreign or domestic vehicle. Call to confirm calibration availability for your specific make and model.

  • What happens if I skip calibration after an accident or windshield replacement?

    Your ADAS features may not work correctly, may give false readings, or may not activate at all. Since these systems are designed to help prevent accidents, driving without proper calibration means losing that layer of protection.

  • Can I choose my own shop for calibration even if my insurance suggests another?

    Yes. Michigan law gives you the right to choose the shop that performs your glass and calibration work, regardless of which shop your insurance company recommends.
