Chevrolet Windshield Replacement in Charleston — Silverado & Safety Assist Calibration

Chevy Safety Assist Calibration Requirements

Key Points in GM's Windshield Replacement Position Statement

• Aftermarket glass: GM writes that it "does not approve and strictly prohibits the use of aftermarket or non-GM Original Equipment (OE) glass for windshield replacement," because aftermarket glass may differ in material, dimensional and optical clarity specifications from what GM validated for the vehicle and its ADAS.
• What triggers calibration: GM states it is critical that a service point calibration or learn procedure is performed whenever a front view windshield camera or sensor is removed, reinstalled, or replaced — or when the windshield itself is removed and replaced. Reusing the original camera on a new windshield does not exempt the vehicle.
• Systems that depend on it: GM names Super Cruise, Adaptive Cruise Control, Automatic Emergency Braking and Lane Keep Assist among the features that rely on precise calibration and integration with sensors and cameras embedded in or mounted near the windshield.
• Acoustic and solar layers: GM says many of its windshields include acoustic dampening to cut wind, road and engine noise, and are engineered to filter UV and infrared rays. Glass without those layers can raise both cabin noise and cabin temperature.
• Optical quality: GM says the optical quality of its windshields is tested to internal standards that go beyond Federal Motor Vehicle Safety Standard (FMVSS) 205, and that inferior glass may increase distortion in the driver's view.
