WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.
The instrument panel cluster (IPC) activates the lights on audible warning. The lights on warning sounds when the following occurs:
- The key is not in the ignition.
- The body control module (BCM) determines that the drivers door is open (signal is low).
- The BCM determines that the headlamp switch is in the park or head position.
