Most newer vehicles have a camera mounted behind the windshield that powers features like lane departure warning, lane-keep assist, automatic emergency braking and adaptive cruise control. These systems are called ADAS, or Advanced Driver Assistance Systems.
When the windshield is replaced, that camera is removed and remounted. Even a tiny change in its angle can mean it's looking at the road slightly wrong. At highway speed, that can put your lane assist or emergency braking off by feet. Recalibration re-aims the camera to the manufacturer's specifications.
Static and Dynamic Recalibration
Static recalibration
Done with the vehicle parked, using precisely placed targets and a scan tool.
Dynamic recalibration
Done by driving the vehicle under set conditions while the system relearns the road.
Some vehicles need one, some need both. We follow the manufacturer's procedure for your specific vehicle.
Recalibration by Brand
Every manufacturer has its own system and its own rules:
Manufacturer Position Statements
Every automaker publishes its own rules for glass replacement and recalibration. Here are the ones for the brands we see most:
- Ford and Lincoln ADAS Job Aid (Ford Motor Company, PDF)
- Aiming Driving Support Systems, Job Aid (August 2025) (American Honda, PDF)
- Use of Aftermarket Windshield Glass for Subaru Vehicles Equipped with EyeSight (Subaru of America position statement, PDF)
- Toyota/Lexus/Scion Glass Replacement Requirements (I-CAR summary of Toyota's repair requirements)
- AGRSS Standard: ADAS language (Auto Glass Safety Council)
Why Have Us Do It
Because we do recalibrations ourselves, on-site, you don't have to take your car to the dealer after we replace the glass. One company, one appointment, and it's done right.
