Millimeter Wave Radar

WARNING: This page is about a different variant/trim than selected.

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 LKAS, and turns on the LKAS indicator.
