There are 2 types of calibrations an auto glass company will perform after installing your windshield, each vehicle is different. These methods are called Static and Dynamic. A Static calibration uses specialized tools and targets (designed to OEM specifications) to ensure the cameras and sensors are properly aligned. Whereas a Dynamic calibration consists of the technician getting behind the wheel and driving in traffic, allowing the camera and sensors to read the road markers and street signs to determine proper placement. For some vehicles, such as Hondas and Subarus, both a Static and Dynamic calibration must be performed before the systems will work properly.
