Warning Chimes - Overview. Description and Operation

Overview

Warning chimes provide the driver with audible alerts that act as reminders and supplement the visual indications from the IPC, such as gauges, indicators and Message Center warnings. The IPC controls all warning chimes based on messages received from external modules. The IPC prioritizes chimes according to a preset hierarchy programmed into the IPC software. When the IPC receives more than one chime request, the most important chime sounds first. If a lower priority chime is currently sounding, a higher priority chime request takes over and replaces or interrupts the lower priority chime.

Warning chimes sound through the audio system speakers and the IPC. The turn signal/hazard flasher (ticking) is the only chime that sounds through the IPC and not the audio system. The Parking Aid and Blind Spot Information System (BLIS®)/Cross Traffic Alert (CTA) chimes sound through the rear speakers. All other warning chimes sound through the front audio system speakers.

The IPC also serves as a backup. If the audio system's audible warning chime fails, the IPC generates all required audible chimes.
