Short answer: ADAS calibration realigns the forward-facing cameras and sensors mounted to your windshield so driver-assist safety features work correctly. It's required after most windshield replacements on vehicles built in the last several years, because removing the old glass moves the camera's reference point even by a fraction of a degree.
ADAS stands for Advanced Driver Assistance Systems — things like lane departure warning, lane keeping assistance, adaptive cruise control, and forward collision warning. Many of these systems rely on a camera mounted directly behind the windshield, near the rearview mirror, to "see" the road.
When your windshield is replaced, the camera is removed and reinstalled on the new glass. During calibration, the ADAS camera is re-aimed and its software is retrained to account for the exact thickness, curvature, and optical properties of the new windshield. This process re-establishes the camera's spatial relationship with the road so it can accurately calculate distance, speed, and lane position.
There are two methods, and many vehicles require both:
An uncalibrated system can misjudge distance, fail to detect lane markings correctly, or delay a response from automatic emergency braking. These systems are designed to assist with real safety events, so this isn't a cosmetic issue — it's why calibration is treated as a required step of a proper windshield replacement, not an optional add-on.
ADAS stands for Advanced Driver Assistance Systems. Calibration is the process of realigning the cameras and sensors mounted to or near your windshield so features like lane keep assist, adaptive cruise control, and automatic emergency braking read the road accurately.
If your vehicle has a forward-facing camera mounted to the windshield, which most vehicles built in the last several years do, then yes, calibration is required after replacement. Vehicles without camera-based driver assist systems don't need it.
Static calibration is performed in the shop using printed targets placed at precise distances from the vehicle. Dynamic calibration is performed by driving the vehicle at a specific speed on the road while the system recalibrates itself. Many vehicles require both.
Your driver assist systems may not read lane markings, other vehicles, or pedestrians accurately, which can cause false warnings, no warnings at all, or a delayed response from features like automatic emergency braking. This is a safety issue, not just a convenience one.
We handle static and dynamic ADAS calibration in-house as part of every qualifying replacement — no separate trip needed.
