Warning Chimes

NOTE: There are instances where some chimes may sound through the IPC and should not be interpreted as a fault in the audio system. An example might be when the ignition is off, with the key in the ignition and the driver door ajar. In this instance, the audio system is offline and the key-in-ignition chime defaults to the IPC.

The IPC uses multiple network messages to control the overall warning chime arbitrator. The IPC arbitrates and controls all chimes regardless if they are sounded through the audio system or the IPC. The warning chimes all sound through the audio system except for the turn signal tick-tock chime which is sounded through the IPC. In the event of an audio system fault, the IPC sounds all chimes. The audio system has the ability to sound up to 2 chimes at a time while the IPC can only sound a single chime at a time.

The warning chimes use volume, chime frequency, length of time the chime sounds, length of off time between chime tones, 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)

ACC Warning Chime

The ACC 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 ACC warning chime sounds through the front speakers. The audio system sounds the appropriate warning chime when it receives the ACC warning request message from the IPMA.

The low priority ACC warning chime is a single-tone, 1-second chime that sounds to alert the driver the ACC 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 ACC operation.

The high priority ACC 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 ACC system can brake the vehicle and the driver needs to apply the brakes to slow the vehicle down.

Airbag Secondary Warning Chime

The airbag secondary warning chime warns the airbag warning indicator LED is inoperative. The airbag secondary warning chime sounds through the front speakers. If the IPC detects a fault with the airbag warning indicator LED during the bulb prove out, the airbag secondary warning chime sounds. If the IPC detects a fault in the airbag warning indicator when a SRS fault condition exists and the RCM has sent the IPC the airbag indicator request, the airbag secondary warning chime sounds. The airbag chime is a 0.5-second chime that sounds 5 times.

BeltMinder® Feature

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

The BeltMinder® is configurable on or off. Refer to Seatbelt Minder Deactivating/Activating .

The BeltMinder® feature supplements the current seatbelt warning function and is enabled after the current seatbelt warning is complete. The BeltMinder® 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 BeltMinder® 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 BeltMinder® chime provides a series of chimes/seatbelt warning indicator flash sequences.

If the vehicle speed drops below 5 km/h (3 mph) once the BeltMinder® 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 BeltMinder® 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.

BLIS®)/ CTA Warning Chime

The BLIS®)/ CTA warning chime alerts the driver that a vehicle has been detected or there is a system fault. The BLIS®)/ CTA warning chime sounds a 0.25-second chime continuously until the request is ended. The chime sounds through the rear speakers.

Door Ajar Warning Chime

The door ajar warning chime warns that a door is ajar and sounds the chime through the front speakers. When a door becomes ajar while the ignition is in RUN with vehicle speed greater than 5 km/h (3 mph), the IPC displays the appropriate door ajar warning message and sounds a single chime tone for each door opened. The door ajar chime only sounds once for each time the door is opened, and only repeats the chime if the door is closed then reopened.

Forward Collision Warning Chime

The forward collision warning chime warns that a forward collision potential has been detected or the CCM detects a forward collision warning system concern. Once the forward collision system detects a possible forward collision, the CCM sends a message to the IPMA over a private CAN. The IPMA sends a message to the IPC through the GWM to flash the forward collision warning in the message center. The IPMA sends a forward collision warning chime request to the IPC through the GWM to sound a 0.25-second chime tone 12 times.

The forward collision warning system and chime can be disabled or turned off using the centerstack display. When MyKey® is in use, the driver cannot configure the forward collision warning system or chime off. When the driver disables the forward collision warning chime, the IPMA sends the IPC the forward collision chime request through the GWM to sound a 0.25-second chime tone 12 times at 50% volume. The forward collision warning chime and confirmation chime are both sounded through the front speakers.

Headlamps On Warning Chime

The headlamps on warning chime warns the headlamps are on when exiting the vehicle. When the driver exits the vehicle with the driver door ajar, the headlamp switch is in the PARK or HEADLAMP position and the ignition is OFF, the IPC sounds the headlamps on chime. The headlamps on chime sounds a 1-second chime tone continuously.

Ignition-Engine On Warning Chime

The ignition-engine on chime informs the driver they are exiting the vehicle when the ignition has been left on (engine off) or the engine is running. When the driver exits the vehicle with the ignition on or with the engine running, the ignition-engine on warning chime sounds five 1-second chime tones. The ignition-engine on warning chime sounds through the front speakers.

Key-In-Ignition Warning Chime

The key-in-ignition warning chime warns the key is still in the ignition lock cylinder or the ignition is in ACC when the driver door is ajar. The key-in-ignition warning chime sounds repetitive 0.5-second chime tones from the front speakers until either the key is removed from the lock cylinder, the ignition is in RUN or the driver door is closed.

Lane Keeping Alert Warning System Chime

The lane keeping alert warning chime alerts the driver they have removed their hands from the steering wheel. The lane keeping alert warning chime sounds three 0.25-second chime tones through the front speakers.

Low Fuel Warning Chime

The low fuel warning chime alerts the driver the fuel level is low. The IPC sounds the low fuel warning chime along with illuminating the low fuel warning indicator or RTT indicator.

Message Center Warning Chime

The message center warning chime feature draws the driver's attention to the message center display to view new warning messages. There are 3 different message center warning chime types that are defined by the length of the chime tone, which are designed to create a greater sense of urgency based on the nature of the condition and message displayed in the message center.

Informational (1-second chime)
Soft warning (0.5-second chime)
Hard warning (0.25-second chime)

Parking Aid Chime

The parking aid system uses a visual display in the centerstack infotainment display and a chime to alert the driver objects are close to the vehicle. The parking aid chime sounds a repetitive chime tone that decreases the time off between chime tones as objects get closer to the sensor until a continuous tone is heard. The parking aid chime sounds through the front speakers for front parking aid, and through the rear speakers for rear parking aid.

Parking Brake Chime

The parking brake warning chime warns the parking brake is engaged when the vehicle is in motion. The parking brake warning chime sounds if the ignition is in RUN, the parking brake is engaged, and the vehicle speed is greater than 5 km/h (3 mph). The parking brake warning chime stops sounding and resets if the parking brake is released, the ignition is not in RUN, the vehicle speed is less than 5 km/h (3 mph), or after 90 seconds from the time the chime is activated. The parking brake warning chime sounds a repetitive 0.5 second chime tone through the front speakers.

Perimeter Alarm Warning Chime

The perimeter alarm warning chime alerts the driver the perimeter alarm is armed when the driver door is unlocked before disarming the alarm. The IPC displays a perimeter alarm message in the message center and the perimeter alarm warning chime sounds for 12 1-second chime tones when the driver door is opened. The perimeter alarm warning chime turns off when the perimeter alarm is disarmed (either by using the key fob or placing the ignition in the ON position). After the twelve second warning chime duration, the warning chime stops sounding and the perimeter alarm activates, sounding the horn and flashing the turn signal lamps.

Seatbelt Warning Chime

The seatbelt warning chime warns the seatbelt is not fastened. The seatbelt warning chime sounds a repetitive 1-second chime tone for 6 seconds through the front speakers when the driver or passenger seatbelt is not fastened and the ignition is transitioned from OFF or ACC to ON or START. The seatbelt warning chime stops sounding when the seatbelt is fastened, when the ignition is transitioned from ON or START to OFF or ACC, or when the chime has sounded for 6 seconds.

Service AdvanceTrac Warning Chime

The service AdvanceTrac warning chime warns the ABS module has detected a fault condition in the stability-traction control system. If a fault condition exists in the stability-traction control system, the ABS module sends the IPC the brake chime request to sound the warning chime. The service AdvanceTrac warning chime sounds 3 0.5-second chime tones through the front speakers.

Transmission Not In Park Warning Chime

The IPC provides a transmission not in park warning chime that sounds along with the transmission not in park message center warning message to inform the driver the vehicle is not in PARK (P). The IPC displays the shift to park message and the transmission not in park warning chime sounds three 0.5-second chime tones if the selector lever is not in PARK (P), the ignition is OFF and the driver door is open or ajar.

Turn Signal On Chime Tone

The IPC provides a repetitive 1-second on/off tick-tock chime tone along with visual RH or LH turn indicators to inform the driver the turn signal or hazard lamp function is on.

Turn Signal Left On Chime

The turn signal left on or turn signal minder chime uses both odometer and turn signal status messages. The turn signal left on chime sounds a repetitive 1-second chime through the front speakers when the vehicle is driven with the turn signal on for more than 3.2 km (2.0 miles).
