Audible Warnings Description and Operation: Notes

The audible warnings alert the driver of a system concern or a critical vehicle condition. The radio generates the audible warnings through the left front speaker. The radio receives audible warning requests via the class 2 serial data line. If the radio receives multiple audible warning requests, the warning with the highest priority sounds first. On vehicles without a radio, the instrument panel cluster (IPC) will produce the chime. Either the radio or the IPC is the chime producer. The following lists the audible warning priority and the pulse rate:

1. Fast rate chime (200 pulses per minute)
2. Medium rate chime (150 pulses per minute)
3. Slow rate chime (50 pulses per minute)
4. Single chime
