As ADAS becomes more common place in modern vehicles and drivers are relying on such advanced systems, the functionality of an ADAS feature could be the difference between avoiding an accident or not.

If your car has Advanced Driver Assistance Systems including: adaptive high beams, rear view cameras to aid parking, a collision detection system, lane departure warnings, autonomous emergency braking, active / adaptive cruise control, pedestrian and traffic sign recognition, vehicle surrounding detection or autonomous night vision etc., etc., these ADAS require routine calibration to ensure they are working as intended. 

So when do you need to get the ADAS system checked or calibrated?
