OPERATION
CHIME PRIORITY
The following list indicates the priority of the chime when more than one chime is active at the same time:
- Seat Belt Warning
- Door Ajar
- Turn Signal On
- Chime Request
- Power Liftgate
The cluster is responsible to set priority on all warning lamp announcement chimes.
CHIME ON CONDITIONS
SEAT BELT UNBUCKLED "BELTMINDER"
There are two different Fasten Seat Belt Reminder announcements incorporated into the cluster's logic, a Non-enhanced announcement and an Enhanced announcement.
When the Enhanced announcement is DISABLED:
- The cluster will chime five times (not greater than six seconds) and illuminate the Seat Belt Lamp after turning the ignition to the run/start position if the driver seat belt is unbuckled.
When the Enhanced announcement is ENABLED;
- The cluster will chime continuously at a slow rate for a period of six seconds and illuminate the Seat Belt Lamp after turning the ignition to the RUN/START position if the driver seat belt is unbuckled. After six seconds the chime will stop, but the Seat Belt Lamp will stay illuminated. If the ignition is in the RUN position for a period greater than 60 seconds, and the driver seat belt is unbuckled, and the vehicle's speed is greater than 8 km/h (5 mph) in a forward gear, the Enhanced Fasten Seat Belt Reminder will activate. This will cause the Seat Belt Lamp to blink and a slow continuous chime to sound for five seconds. After five seconds, the chime will stop, but the lamp will remain illuminated for an additional three seconds. The Enhanced Seat Belt Reminder cycles for a total of 12 times (96 seconds). After the 12th time, the Seat Belt Lamp will remain on without any chime. Buckling the driver seat belt at anytime will cancel the Fasten Seat Belt Reminder announcement.
The seat belt indicator includes a programmable enhanced seat belt reminder or "beltminder" feature that is enabled when the vehicle is shipped from the factory. This beltminder feature can be disabled and enabled by the customer using a specific programming event sequence, or by the dealer using a diagnostic scan tool.
EXTERIOR LIGHTS ON
Chime sounds if the ignition is in the lock position, the driver's door is ajar, and the headlight switch is in any position other than auto or off. The chime will continue to sound until anyone of the above conditions change or the battery protection time of 3 minutes expires.
KEY-IN IGNITION
Chime sounds if the key is in the ignition, the ignition is in the lock position, and the driver's door is ajar. The chime will continue to sound until anyone of the above conditions change.
TURN SIGNAL ON
If the BCM detects a turn signal input continuously for 1.6 km (1.0 mile) and the vehicle speed is greater than 24 km/h (15 mph), the cluster will chime continuously and display an EVIC warning message, until the turn signal is cancelled.
LOW OIL PRESSURE
Chime sounds when the engine is operating and the oil pressure drops below 4 psi/27.5 kPa.
ENGINE TEMPERATURE CRITICAL
Chime sounds when the engine is operating and the coolant temperature exceeds 122° C (252° F). The chime is continuous at 125° C (257° F) and will chime for 4 minutes and stop if the temperature drops below 117° C (243° F).
LOW WASHER FLUID
Chime sounds when the washer fluid drops below a specific level.
WARNING LAMP ANNOUNCEMENT
Chime sounds to alert the driver to scan the EVIC (in the cluster) to see which EVIC warning message displayed. The door/liftgate ajar warning message will display (without a chime) if the vehicle is running and a door or the liftgate is open. A chime will sound if the door or liftgate is still open when vehicle speed is greater than 1.6 km/h (1 mph).
WARNING LAMP ANNOUNCEMENT
LOW FUEL LAMP
The cluster will sound a single chime, illuminate an amber lamp, and display an EVIC warning message after illuminating the indicator.
VOLT LAMP
The cluster will sound a single chime after illuminating the indicator.
OIL PRESSURE LAMP
The cluster will sound a single chime after illuminating the indicator above 450 rpm vehicle operation.
FASTEN SEAT BELT LAMP
There are two different Fasten Seat Belt Reminder announcements incorporated into the cluster's logic, a Non-enhanced announcement and an Enhanced announcement.
When the Enhanced announcement is DISABLED:
- The cluster will chime five times (not greater than six seconds) and illuminate the Seat Belt Lamp after turning the ignition to the RUN/START position if the driver seat belt is unbuckled.
When the Enhanced announcement is ENABLED;
- The cluster will chime continuously at a slow rate for a period of 6 seconds and illuminate the Seat Belt Lamp after turning the ignition to the run/start position if the driver/passenger seat belt is unbuckled. After six seconds the chime will stop, but the Seat Belt Lamp will stay illuminated. If the ignition is in the RUN position for a period greater than 60 seconds, and the driver seat belt is unbuckled, and the vehicle's speed is greater than 8 km/h (5 mph) in a forward gear, the Enhanced Fasten Seat Belt Reminder will activate. This will cause the Seat Belt Lamp to blink and a slow continuous chime to sound for five seconds. After five seconds, the chime will stop, but the lamp will remain illuminated for an additional three seconds. The Enhanced Seat Belt Reminder cycles for a total of 12 times (96 seconds). After the 12th time, the Seat Belt Lamp will remain on without any chime. Buckling the driver seat belt at anytime will cancel the Fasten Seat Belt Reminder announcement.
The seat belt indicator includes a programmable enhanced seat belt reminder or "beltminder" feature that is enabled when the vehicle is shipped from the factory. This beltminder feature can be disabled and enabled by the customer using a specific programming event sequence, or by the dealer using a diagnostic scan tool.
The instrument cluster will turn on the seat belt indicator for the following reasons:
- Seat Belt Reminder Function - Each time the cluster receives a battery current input on the fused ignition switch output (run-start) circuit, the indicator will be illuminated as a seat belt reminder for about six seconds, or until the ignition switch is turned to the Off position, whichever occurs first. This reminder function will occur regardless of the status of the seat belt switch inputs to the cluster.
- Front Seat Belt Not Buckled - Beltminder Active - Following the seat belt reminder function, each time the cluster detects an open circuit on either of the front seat belt switch sense circuits (seat belt switch open = seat belt unbuckled) with the ignition switch in the Start or On positions, the indicator will be illuminated. In addition, if the front seat belt remains unbuckled about sixty seconds after the conclusion of the seat belt reminder function with the vehicle speed greater than about 8 km/h (5 mph), the seat belt indicator will begin to cycle between flashing on and off for three seconds, then lighting solid for two seconds. The seat belt indicator will continue to cycle between flashing and solid illumination for thirteen complete cycles, until the seat belt switch sense inputs to the cluster are closed circuits to ground (seat belt switch closed = seat belt buckled), or until the ignition switch is turned to the Off position, whichever occurs first.
- Front Seat Belt Not Buckled - Beltminder Inactive - Following the seat belt reminder function, each time the cluster detects an open circuit on either of the seat belt switch sense circuits (seat belt switch open = seat belt unbuckled) with the ignition switch in the Start or On positions, the indicator will be illuminated. The seat belt indicator remains illuminated until the seat belt indicator driver inputs to the cluster are closed circuits to ground (seat belt switch closed = seat belt buckled), or until the ignition switch is turned to the Off position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the seat belt indicator will be turned on, then off again during the bulb check portion of the test to confirm the functionality of the LED and the cluster control circuitry.
CHECK ENGINE LAMP
The cluster will sound a single chime after illuminating the indicator.
ENGINE TEMPERATURE LAMP
The cluster will sound a single chime when the indicator first illuminates at 122° C (252° F).
TRACTION CONTROL LAMP
The cluster will sound a chime, illuminate an indicator lamp, and display an EVIC warning message after illuminating the indicator if the traction control system:
- is active.
- is suspended.
- needs service.
- is disabled by the driver.
TURN SIGNAL ON
If the BCM detects a turn signal input continuously for 1.6 km (1.0 mile) and the vehicle speed is greater than 24 km/h (15 mph), the cluster will chime continuously, illuminate an amber message indicator lamp, and display an EVIC warning message, until the turn signal is cancelled.
OTHER CHIME ON CONDITIONS

- The key fob with a low battery.
- An invalid key fob and key.
SERVICE IMMOBILIZER
The cluster will sound a chime and display an EVIC message when there is a problem with the SKREEM Module.
POWER LIFTGATE
The cluster will sound a chime and display an EVIC message when there is a power liftgate actuation with the:
- Overhead console or RKE and the doors are locked.
- Overhead console and the vehicle is not in park.
- Overhead console or RKE and the temperature is too cold for actuation.
- Overhead console or RKE and the temperature is too hot for actuation.
TIRE PRESSURE MONITOR SYSTEM
The tire pressure monitoring system will request:
- A chime, illuminate an amber TPM lamp, and display an EVIC message when the system senses that there is a low tire pressure problem.
- To illuminate an amber TPM lamp, and display an EVIC message when the system senses that one of the four original tires on the vehicle has been changed.
- A chime, illuminate an amber TPM lamp, and display an EVIC message if the system does not sense any tire pressure.
- A chime, illuminate an amber TPM lamp, and display an EVIC message when the tire system needs service.
- The LED will flash for 60 seconds and turn off for 9 minutes. It repeats this 10 minutes sequence until corrected.
PARK ASSIST SYSTEM
The Park Assist System display activates an audible tone that changes from intermittent to continuous as the final two Light Emitting Diodes (LED's) are illuminated on one side or both sides of the display.
The system detection length from the rear of the vehicle is about 0.3 - 1.5 meters (1 - 5 ft.). This area extends around the rear side of the vehicle. The system detection height from the ground is about 0.2 - 1.5 meters (1 - 5 ft.). The radio mutes when the system activates its audible tone.
When the driver selects Reverse, the system scans for objects behind the vehicle using four sensors located in the rear bumper. A warning display above the rear window provides both visible and audible warnings indicating the range of the object.
The system is active only when the transmission gear selector is in reverse for vehicle speeds less than 16 km/h (10 mph). If the vehicle's Parking/Emergency Brake is applied, the system is deactivated.
The display contains two sets of yellow and red Light Emitting Diodes (LED's) that the driver can see as they look over their shoulder while backing up. Each side of the vehicle has its own warning LED's. The system provides a visual warning by illuminating one or more yellow LED's as the vehicle gets closer to the object. As the vehicle continues to approach the object, one red LED is illuminated and the system emits a series of short beeps. The tone will remain constant and both red LED's are illuminated once the vehicle is within 30.5 cm (12 inches) of the object.
The system can be turned ON or OFF through the Electronic Vehicle Information Center (EVIC) when the vehicle is in PARK. If the park assist system is turned OFF, a single chime will sound and the EVIC will display the following message "REAR PARK ASSIST DISABLED", when the vehicle is in reverse.
- Ensure that the rear bumper is free of dirt and debris to keep the system operating properly.
- Jackhammers, large trucks, and other vibrations could affect the performance of the system.
- Ensure that the parking brake is not applied.
If "Service Park Assist System" appears in the EVIC after making sure the rear bumper is clean, proceed to diagnose the system using a scan tool and the appropriate diagnostic information.
