Why is it essential to ensure proper calibration of advanced driver assistance systems (ADAS) after windshield replacement?

Ensuring proper calibration of advanced driver assistance systems (ADAS) after a windshield replacement is crucial because these systems depend on sensors that are often integrated into or around the windshield. These sensors, including cameras and radar, need to be accurately aligned to function correctly and ensure the safety and reliability of the vehicle’s driving assistance features. When the windshield is replaced, the physical and optical properties of the new glass can differ, which can affect the way these systems perceive their environment.

Additionally, proper calibration allows the vehicle's systems to interpret data correctly, maintaining the effectiveness of features such as lane departure warning, adaptive cruise control, and automatic emergency braking. Misaligned sensors could lead to inaccurate readings, putting the driver, passengers, and others on the road at risk. Therefore, calibrating these systems after replacing the windshield is fundamental to uphold vehicle safety and operational integrity. The other options do not adequately address the role of calibration in maintaining the functionality of ADAS, focusing instead on misconceptions about its necessity or scope.
