The multifunction alarm module produces an audible warning to alert the driver of a system concern or a critical vehicle condition. If multiple audible warnings requests are received at the same time, the warning with the highest priority will sound first. The following lists the audible warning priority and pulse rate:

1. Fast rate chime (150 pulses per min)
2. Medium rate chime (100 pulses per min)
3. Slow rate chime (50 pulses per min)

The multifunction alarm module senses that the driver's seat belt is not buckled (signal is low). The multifunction alarm module sends a message to the IPC requesting illumination of the seat belt indicator. The seat belt chime sounds at the rate of 50 pulses per minute (slow rate chime) for a duration of approximately 6 seconds. The fasten safety belt warning sounds and the seat belt indicator illuminates when the following occurs:

If the seat belt is buckled when the ignition is turned on, the chime will not sound. If the seat belt is buckled while the chime is sounding, the chime stops.

When the multifunction alarm module detects the key is in the ignition (signal is low) and the driver's door is open, it activates an audible warning. The key-in-ignition chime sounds at the rate of 100 pulses per minute (medium rate chime) until the driver door is closed or the key removed from the ignition switch. The multifunction alarm module activates the key-in-ignition warning when all of the following occurs:

The multifunction alarm module will activate an audible warning as a reminder that the headlamps are left on when exiting the vehicle with the ignition switch in the off position. The lights on warning sounds at the rate of 150 pulses per minute (fast rate chime) until the headlamp switch in turned off. The multifunction alarm module receives a signal from the headlamp and panel dimmer switch via the TAIL relay. The multifunction alarm module activates the lights on warning chime when the following occurs:
