Message Center Warning Chime
WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The message center warning chime feature is used to draw the driver's attention to the message center display to view a new warning message or message center warning indicator displayed. The IPC provides a single one-second tone whenever a new warning message is displayed in the message center. If multiple warning messages are present, the IPC sounds a chime for each of the warning messages that are present.
