Additional Warnings

The following warnings have an associated instrument panel cluster (IPC) indicator:

• Hot coolant temperature-The audio amplifier activates the audible warning as requested by the body control module (BCM) or the ECM/PCM. The BCM sends a GMLAN message to the audio amplifier indicating the chime frequency of a medium rate and at a continuous duration.
• Low fuel-The audio amplifier activates the audible warning as requested by the BCM. The BCM sends a GMLAN message to the audio amplifier indicating the chime frequency of a medium rate and at a continuous duration.
• Low engine oil pressure-The audio amplifier activates the audible warning as requested by the IPC. The BCM sends a GMLAN message to the audio amplifier indicating the chime frequency of a medium rate and at a continuous duration. The low engine oil pressure indicator will be ON in the IPC.
