This driver assistance system uses forward-facing radar, lidar, or stereoscopic cameras to detect traffic speed and distance. It automatically applies the throttle or brakes to keep the vehicle at a safe, pre-selected following distance. Technicians must precisely recalibrate the sensors after windshield replacements or front-end collision repairs.
Heard on the job
The automatic distance control threw a fault code because the front radar bracket got bent in a fender bender.
Insider tip
A dirty front bumper emblem or a heavy snowstorm will often disable this system temporarily by blocking the radar emitter.
