The audible warnings alert the driver of a system concern or a critical vehicle condition. The radio generates the audible warning through the left front speaker. The radio receives audible warning requests via the serial data circuit. If the radio receives multiple audible warning requests, the warning with the highest priority sounds first. On vehicles without a radio, a chime module generates the audible warnings and receives audible warning requests via the serial data circuit. Either the radio or the chime module is the chime procedure. The following lists the audible warning priority and the pulse rate:
- Fast rate chime - 200 pulses per minute
- Medium rate chime - 150 pulses per minute
- Slow rate chime - 50 pulses per minute
- Single chime
