If your Pontiac Grand Am uses a forward-facing camera behind the windshield, replacement may include ADAS calibration—not just glass installation. Systems like lane keep assist, lane departure warning, automatic emergency braking, adaptive cruise control, and traffic sign recognition rely on a camera that “sees” through the windshield. A new windshield, a bracket transfer, or slight positioning differences can require recalibration so the camera’s aim and interpretation match factory specifications. The extra time usually follows a clear workflow: a pre-scan, calibration, and post-scan verification. The pre-scan checks for diagnostic trouble codes (DTCs) and documents system status before work begins. Calibration can be static, dynamic, or both depending on Pontiac Grand Am requirements. Static calibration is performed in a controlled setup using targets, specified distances, and measured alignment. Dynamic calibration is a guided drive where the vehicle uses roadway cues—like lane markings—to relearn reference points. A post-scan confirms results and verifies the system is within tolerance. Not every Pontiac Grand Am requires calibration, and timing can range from a brief add-on to a longer window that depends on equipment, space, and driving conditions.
