Warning Chime Characteristics
Each warning chime has unique characteristics that help to identify and differentiate each warning chime. The warning chimes use volume, chime frequency, length of time the chime sounds and the number of chime tones to identify which chime is sounding. The IC prioritizes the chimes according to a preset hierarchy programmed into the IC software. Generally, when more than one chime request is received by the IC, the most important chime sounds. If a lower priority chime is currently sounding, the higher priority request takes over and replaces the lower priority chime.
There are 3 different chimes as listed below:
- Repetitive
- Single tone
- Tick-tock
The following table provides a summary of the chime characteristics including the chime priority.

| Door/trunk ajar | Single tone | A single one-second tone chime that sounds whenever the IC receives a door ajar message. |

| Key-in-ignition | Repetitive | Continuous 0.5 second chimes or 120 chimes per minute. On for as long as the key is in the ignition with the door ajar and the IC receives the chime on command. |
| Message center | Single tone | This is a single one-second tone chime that sounds once per ignition cycle whenever the IC receives a new message commanding on one of the message center warnings. |
| Parking brake on | Repetitive | On for as long as the parking brake is applied and the IC receives the chime on command. |
