Adaptive Cruise Control Warning Chime

The adaptive cruise control warning chime supplements the message center displays to draw the drivers 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 of the warning.

The low priority adaptive cruise control warning chime is a single-tone chime that sounds to alert the driver that the adaptive cruise control system has shut itself off due to low vehicle speed (approximately 30 km/h [18.6 mph]) and that 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 also a single-tone that is longer than the low priority chime to increase intensity and alert the driver that the vehicle is approaching the vehicle ahead at a faster rate than the adaptive cruise control system can brake the vehicle and that the driver needs to intervene and apply the brakes to slow the vehicle down.

Both the low and high priority adaptive cruise control warning chimes are accompanied by the DRIVER INTERVENE warning message.

The adaptive cruise control warning chime inputs are:

• Ignition state.
• Adaptive cruise control warning chime request communicated by the Cruise-Control Module (C-CM) to the IPC over the HS-CAN.
