Modern windshields are more than just a barrier against the elements—they’re integral to the functionality of many ADAS features. Most notably, they house the forward-facing cameras that are essential for systems like Lane Departure Warning (LDW), Lane Keeping Assist (LKA), and Forward Collision Warning (FCW). When you get a new windshield, even if it’s installed perfectly, there’s a chance that the camera’s calibration could be off.

​

Consider this: you’re driving down a winding road at night, and your Lane Departure Warning system doesn’t alert you when you start to drift toward the center line. This could happen because the camera isn’t correctly calibrated to recognize the road’s markings after the windshield replacement. The consequences can be severe, especially in low-visibility conditions where you rely more heavily on these systems. Similarly, if the Forward Collision Warning system doesn’t correctly judge distances, it might not alert you in time to avoid a collision.

Calibration ensures that after a new windshield is installed, the cameras are perfectly aligned to view the road exactly as the manufacturer intended. This step is crucial to maintaining the reliability of your ADAS features.
