Understanding ADAS Calibration: Why It Matters After Windshield Replacement

If your vehicle was manufactured after 2016, chances are it has Advanced Driver Assistance Systems (ADAS) that require careful calibration after windshield replacement.

What is ADAS? ADAS includes features like lane departure warning, automatic emergency braking, adaptive cruise control, and collision avoidance—all of which rely on cameras and sensors mounted to or near your windshield.

Why Calibration Matters When your windshield is replaced, even a millimeter of misalignment in the camera can cause these safety systems to malfunction. Imagine your lane departure system giving false warnings or your emergency braking activating at the wrong time.

Types of Calibration - Static Calibration: Performed in a controlled environment using specific targets positioned at precise distances from the vehicle. - Dynamic Calibration: Requires driving the vehicle at specific speeds while the system recalibrates itself using road markings.

Ask About the Required Procedure Calibration requirements vary by vehicle and windshield configuration. Before authorizing work, ask whether your vehicle requires static calibration, dynamic calibration, or both; who will perform it; and what documentation you will receive. Follow the vehicle manufacturer's current service information rather than assuming every replacement uses the same process.
