Instrument Panel Cluster
WARNING: This page is about a different car, the 2010 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
The instrument panel cluster (IPC) contains the green and amber land departure warning indicators. These indicate to the driver the current status of the lane departure warning system and are controlled via serial data by the VDAAW. When the system has detected the required lane markings and is ready to assist, the green indicator will be illuminated on the IPC. If the vehicle has unintentionally left the lane, the amber indicator will flash.
