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 lane departure warning is controlled by the frontview camera module mounted on the windshield. The lane departure warning is enabled and disabled through a switch located at the instrument panel. When enabled, the vehicle direction camera control module will illuminate the indicator located in the switch.

When the system is operating and can detect the lane markings, the vehicle direction camera control module will request via serial data communications that the instrument cluster illuminate the green lane departure ready-to-assist indicator. If the frontview camera module detects that the vehicle has crossed a lane marking without the turn signal being used, the module will request that the instrument cluster flash the yellow lane departure warning indicator. An audible warning will also sound three times when the yellow instrument cluster indicator is flashing.
