Headlamps Suggested Warning
WARNING: This page is about a different car, the 2002 Oldsmobile Aurora and 2001 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
The radio activates the headlamps suggested warning as requested by the IPC. The IPC sends a class 2 message to the radio indicating the chime frequency and the duration. The headlamps suggested warning sounds, and the HEADLAMPS SUGGESTED message displays in the DIC when the IPM detects a low ambient light condition, and the vehicle is not in park or neutral.
