Circuit/System Description

WARNING: This page is about a different car, the 2012 GMC Terrain and 2012 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.

The lane departure warning system is controlled by the front view camera module mounted on the windshield. The lane departure warning is enabled and disabled through a switch located in the steering wheel. When enabled, the front view camera module will illuminate the amber indicator located in the switch.

When the system is operating and can detect the lane markings, the front view camera module will request via serial data communications that the instrument cluster illuminates the green lane departure ready-to-assist indicator. If the front view camera module detects that the vehicle unintentionally crosses a lane marking without the turn signal being used, the module will request the vehicle direction display to flash the amber lane departure warning indicator. An audible warning will also sound three times when the amber lane departure warning indicator in the vehicle direction display is flashing.
