Warning Chime Characteristics

The warning chimes use volume, chime frequency, length of time the chime sounds, decay of the chime tone and the number of chime tones to identify which chime is sounding. Most warning chimes have unique characteristics, however, there are chimes that do sound the same. The chime characteristics are defined by the different chime types:

• Information
• Soft-warning
• Hard-warning
• Tick-tock (on-off)

Active Park Assist Chime

The active park assist system uses informational and instructional messages displayed in the FDIM to direct the driver's interaction with the system. The active park assist system chimes alert or to draw the driver's attention to the requested actions. The active park assist chime sounds through the front speakers.

The IPC receives the active park assist chime request from the GWM over the HS-CAN3 .

The GWM receives the active park assist chime request from the PAM over the HS-CAN1 .

The IPC then sends the IPC chime request message to the ACM or the DSP (with Revel audio system) to sound the chime.

Adaptive Cruise Control Warning Chime

The adaptive cruise control warning chime supplements the message center displays to draw the driver's attention to the need to intervene and take control of the vehicle. There are 2 levels of chime output (high priority and low priority) based upon the nature and urgency of the warning. The adaptive cruise control warning chime sounds through the front speakers. The audio system sounds the appropriate warning chime when it receives the adaptive cruise control warning request (high priority chime) or cruise control status (low priority chime) message from the IPMA .

The low priority adaptive cruise control warning chime is a single-tone, 1-second chime alerts the driver that the adaptive cruise control system has shut itself off due to low vehicle speed (approximately 32 km/h [20 mph]) and the driver needs to intervene if further braking is required or to resume the adaptive cruise control operation.

The high priority adaptive cruise control warning chime is a 0.25-second chime that sounds 12 times. The chime alerts the driver the vehicle is approaching the vehicle ahead at a faster rate than the adaptive cruise control system can brake the vehicle and the driver needs to apply the brakes to slow the vehicle down.

The IPC receives the cruise control status and the adaptive cruise control warning request messages from the GWM over the HS-CAN3 .

The GWM receives the cruise control status message from the PCM over the HS-CAN1 .

The GWM receives the adaptive cruise control warning request message from the IPMA over the HS-CAN2 .

When a chime request is received, the IPC sends the IPC chime request message to the ACM or the audio DSP (with Revel audio system) to sound the chime.

Backup Warning Chime (China Only)

The backup warning chime warns the driver the vehicle is in reverse. When the selector lever is in reverse, the PCM sends the gear lever position message to the GWM over the HS-CAN1 . The GWM sends the gear position status message to the IPC over the HS-CAN3 to sound a 1-second chime tone continuously through the front speakers.

Belt-Minder® Feature

NOTE: Whenever the vehicle is operated using MyKey®, the IPC enables the Belt-Minder®.

The Belt-Minder® is configurable on or off.
Refer to: Seatbelt Minder Deactivating/Activating (413-01 Instrumentation, Message Center and Warning Chimes, General Procedures).

The Belt-Minder® feature supplements the current seatbelt warning function and is enabled after the current seatbelt warning is complete. The Belt-Minder® reminds the driver the driver or front passenger seatbelt is unbuckled by intermittently sounding a chime and simultaneously illuminating the seatbelt warning indicator through the front speakers. The Belt-Minder® begins once the current seatbelt warning has ended and the vehicle speed has exceeded 10 km/h (6 mph) with the driver or front passenger seatbelt unbuckled. While activated, the Belt-Minder® chime provides a series of chimes/seatbelt warning indicator flash sequences.

If the vehicle speed drops below 5 km/h (3 mph) once the Belt-Minder® chime has activated, the chime turns off and the seatbelt warning indicator remains on. When the vehicle speed exceeds 10 km/h (6 mph) again, the Belt-Minder® chime resumes.

When MyKey® is in use, the driver cannot configure the Belt-Minder® off. Once the Belt-Minder® is activated, the Belt-Minder® continues to chime periodically (does not time out after 5 minutes) and the audio system is muted until the driver and passenger seatbelts are fastened.

To control the Belt-Minder®, the IPC receives the vehicle speed, gear lever position, driver and passenger seatbelt buckle status and front passenger detect status messages from the GWM over the HS-CAN3

The GWM receives the vehicle speed and gear lever position messages from the PCM over the HS-CAN1
