What is the purpose of recalibration after windshield replacement?

• A. To adjust the engine timing
• B. To ensure the camera and sensors function correctly
• C. To recalibrate the air conditioning system
• D. To recalibrate the tires

Answer: (B)

Recalibration after windshield replacement is needed so the vehicle’s forward-looking camera and sensors are precisely aligned with the car’s geometry. Modern cars use ADAS features like lane-keeping, automatic braking, and adaptive cruise control, which rely on accurate readings from those cameras and sensors. If the windshield is replaced, the reference position can shift, and without recalibration the system may misinterpret what it sees, leading to false warnings, unnecessary alerts, or features not functioning as intended. This process ensures the safety features respond correctly to real road conditions. It isn’t related to engine timing, the air conditioning system, or tires, which is why those areas aren’t addressed during windshield recalibration.
