Millimeter Wave Radar

The millimeter wave radar measures the distance between your vehicle and the vehicle directly ahead to calculate the difference in speed between the vehicles.

The millimeter wave radar has a self-diagnostic function. If the system detects a problem, it disables the CMBS, and turns on the CMBS indicator.
