Circuit/System Description

WARNING: This page is about a different car, the 2016 GMC Acadia, 2016 Chevrolet Traverse, and 2016 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.

The forward collision alert system is controlled by the front view camera module mounted on the windshield. The forward collision alert system is always active and operates at speeds above 40 km/h (25 mph). When the system detects a vehicle in the path ahead, the green vehicle ahead alert indicator in the vehicle direction display is illuminated. When approaching another vehicle too rapidly, the collision alert symbol will flash in the display located in the center of the instrument panel and the radio will simultaneously give an audible alert sound. The red collision alert display will stay continuously illuminated if the vehicle ahead remains much too close. These actions are requested by the front view camera module via serial data to the instrument cluster. The instrument cluster provides the ground path to turn on the appropriate LEDs. The forward collision alert switch is used to adjust the timing sensitivity of the front collision alert system.
