Why Do Some Vehicles Need Camera Calibration After a New Windshield?

Summary:

Mike explains that some vehicles require camera calibration after a windshield replacement because they are equipped with specific safety features. The main one is the lane departure warning system, which also interacts with multiple other safety features on the vehicle. The camera for these systems is mounted on the windshield, so anytime the windshield is removed and the camera is unplugged, the camera has to be recalibrated afterward. He stresses that recalibration is required per the service instructions from the manufacturer. It is not an optional extra; it is what the manufacturer says you are supposed to do, and it is what NW Autoglass Solutions does on those vehicles.

Answer:

Some vehicles need camera calibration after a replacement because they are equipped with specific safety features. The big one is the lane departure warning system, which also interacts with multiple other safety features of the vehicle. Those systems rely on a camera that sits on the windshield, so the position of that camera matters. Anytime you remove that windshield and unplug that camera, it has to be recalibrated afterward per the service instructions. That is per the service instructions from any manufacturer. That is what you are supposed to do, so that is what we do. It is not a step you can skip just because the glass is in and the car drives fine. The camera has to be told exactly where it is sitting again so the lane departure system and the other safety features that tie into it work the way the manufacturer designed them to. So if your vehicle has those features, calibration is part of the job.
