Many modern vehicles are equipped with Advanced Driver Assistance Systems (ADAS), which include features like lane departure warning, adaptive cruise control, automatic emergency braking, and forward collision alerts. These systems rely on sensors and cameras that are often mounted on or near the windshield.
If a windshield is replaced, the ADAS cameras may become misaligned, which can cause these safety features to malfunction. This is why ADAS calibration is essential after a windshield replacement to ensure that all systems work correctly and provide accurate readings.
What Is ADAS Calibration?
ADAS calibration is the process of reconfiguring and aligning the sensors and cameras that control a vehicle’s driver assistance features. This ensures that they accurately detect objects, lane markings, and surrounding vehicles.
There are two main types of ADAS calibration:
Static Calibration – Performed in a controlled environment using specialized targets and tools to recalibrate the sensors.
Dynamic Calibration – Requires driving the vehicle under specific conditions while the system makes real-time adjustments.
Some vehicles require one type of calibration, while others need both. A professional technician will determine the correct method based on the manufacturer’s specifications.
Why Is ADAS Calibration Necessary After Windshield Replacement?
If the windshield is replaced without recalibrating the ADAS system, the cameras may no longer be positioned correctly, leading to inaccurate readings and reduced effectiveness of safety features.
Dangers of Skipping ADAS Calibration:
Lane departure warning may not activate correctly, increasing the risk of drifting into another lane.
Automatic emergency braking may not detect obstacles properly, delaying braking response.
Adaptive cruise control may not maintain the correct distance from other vehicles, leading to unsafe driving conditions.
Forward collision warning may fail to detect vehicles or pedestrians, reducing reaction time in an emergency.
Even a minor misalignment of a few millimeters can significantly impact how the system functions. ADAS calibration ensures that all safety features work as intended, protecting both the driver and other road users.
How Do You Know If Your Vehicle Needs ADAS Calibration?
If your vehicle has any of the following features, it requires ADAS calibration after a windshield replacement:
Lane departure warning
Adaptive cruise control
Forward collision warning
Automatic emergency braking
Blind-spot monitoring
Traffic sign recognition
Driver attention monitoring
Most newer vehicles have at least one ADAS feature that relies on windshield-mounted cameras. Always check your owner’s manual or consult with a professional auto glass technician to confirm if calibration is needed.
What Happens During ADAS Calibration?
After replacing the windshield, a trained technician will use specialized equipment to align the cameras and sensors. The process typically includes:
System Scan – The technician connects a diagnostic tool to check for any ADAS error codes.
Alignment Adjustment – Using manufacturer-approved targets and tools, the technician recalibrates the cameras to ensure proper positioning.
Test Drive (If Required) – For dynamic calibration, the vehicle must be driven at specific speeds under controlled conditions to allow the system to adjust.
Final System Check – A post-calibration scan ensures that all ADAS features are functioning correctly.
Calibration times vary depending on the vehicle make and model but typically take between 30 minutes to 2 hours.
ADAS Calibration Is Always Covered by Insurance
If you have comprehensive auto insurance, ADAS calibration is always covered as part of a windshield replacement. This means you do not have to pay extra for calibration services.
Key Insurance Coverage Details:
ADAS calibration is automatically included in insurance-covered windshield replacements.
There are no additional out-of-pocket costs for calibration if you have full auto glass coverage.
Skipping calibration can void insurance claims and vehicle warranties, making proper alignment essential.
Because ADAS systems are a critical part of vehicle safety, insurance providers ensure that calibration is done correctly when a windshield is replaced.
What Happens If ADAS Calibration Is Done Incorrectly?
If ADAS calibration is not performed correctly, safety systems may not work as expected. This can lead to:
False alarms or warnings that trigger unexpectedly.
Delayed braking or incorrect distance measurement for adaptive cruise control.
Failure to detect lane markings, pedestrians, or other vehicles properly.
Always choose an experienced auto glass service that has the tools and training to perform proper ADAS calibration.
Final Thoughts: Why ADAS Calibration Matters After Windshield Replacement
ADAS technology plays a critical role in vehicle safety, and failing to calibrate these systems after a windshield replacement can lead to serious risks. Proper calibration ensures that lane departure warnings, automatic braking, and other safety features function accurately.
