Also Known As:

• Millimetre Wave Radar
• Pre-Crash System
• Long Range Radar

How it Works: The radar emits radio waves, which bounce off objects and return to the sensor. The time and strength of the return signal determines distance and speed.

Location:

• Behind the front bumper or front grille emblem

Calibration Required When:

• Radar is removed, disturbed, or replaced
• Vehicle has had front-end impact repairs
• Front bumper, grille, or badge is replaced
• Wheel alignment is performed (in some OEMs)

Common Failures:

• Installed backwards or upside down
• The mounting bracket is bent after an accident
• Incorrect vertical / horizontal angles
• Hidden damage from drops or impacts

Common Applications:

• Volkswagen Passat, Golf (2015+)
• Ford Ranger, Everest (2019+)
• Toyota Hilux, Prado (2017+)
• Mercedes-Benz C, E, and GLC classes (2016+)
