ADAS stands for Advanced Driver Assistance Systems
These auto safety features make up of a series of systems and sensors that help enhance driver safety. ADAS calibration (and recalibration) is the precise physical alignment, testing, and electronic aiming needed to ensure factory specifications are met.
Advanced Driver Assistance Systems (ADAS) recalibration is crutial during a windshield replacement because the forward-facing cameras and sensors that power your vehicle's safety features are mounted directly onto or right behind the glass. Replacing the windshield inherently disturbs these components. If they are not precisely recalibrated afterward, your vehicle’s automated safety features will fail, malfunction, or shut down completely. Certain comforts such as cruise control may not work either if the ADAS recalibration is not performed after a windshield is replaced.
We can let you know if your vehicle requires this type of recalibration and what type of recalibration is right for your vehicle. Most comprehensive auto insurance policies cover the cost of calibration as part of a glass replacement claim
Why Windshield Replacement Disrupts ADAS systems
- Physical Displacement: Techs must physically detach the camera from its bracket on the old windshield and mount it onto the new glass.
- Microscopic Misalignment: Shifts as tiny as a single millimeter or a fraction of a degree throw off the camera's viewing angle.
- Glass Variance: Minor differences in glass thickness, curvature, or optical clarity between the old and new windshield alter how light hits the lens.
High-Stakes Risks of Skipping Calibration
Driving without post-replacement calibration is dangerous because the vehicle's "eyes" can no longer accurately judge distances or road markings.
- Failed Emergency Braking: A misaligned sensor may fail to detect a stopped vehicle ahead, delaying or completely missing automatic emergency braking.
- Erratic Lane Interventions: Your car may misread lane lines, causing the lane-keep assist to pull the steering wheel unexpectedly or fail to warn you when drifting.
- Adaptive Cruise Mishaps: The radar and camera system may misjudge following distances, creating hazards at highway speeds.
- System Shutdown: Many modern vehicles instantly detect the sensor displacement, trigger error codes, and disable automated features until calibration occurs.
Benefits of the Required Calibration
- Safety First: Accurate calibration ensures all safety systems work as they should, protecting you and your passengers.
- Optimal Performance: Maintain the performance of ADAS features to reduce the risk of accidents.
- Compliance: Calibration meets manufacturer specifications, ensuring your vehicle remains in line with safety standards.
Do not skip this vital step! Always ensure calibration is part of your windshield replacement process. Your safety depends on it!
How the Calibration Process Works
We utilize specialized equipment to restore your vehicle to strict factory specifications. Depending on your vehicle make and model, technicians use one or both of these standard methods.
Static Calibration: Done inside a controlled environment using physical target boards and laser leveling. Level floor, precise lighting, and zero background clutter.
Dynamic Calibration: Done on the road by driving the vehicle at a specified speed for a set distance. Clear road markings, optimal weather, and a diagnostic scan tool connected to work through the vehicles calibration requirements.
