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 GMLAN serial data line. If the radio receives multiple audible warning requests, the warning with the highest priority sounds first. The following lists the audible warning priority and the pulse rate:

• Fast rate chime (200 pulses per minute)

• Slow rate chime (50 pulses per minute)
