Chime Warning System
The chime warning system operates on battery voltage received on a non-switched fused B(+) circuit so that the system may operate regardless of the status of the ignition switch. The chime warning system also monitors the ignition switch status so that some chime features are functional only when the status of the ignition switch is On, while others are functional regardless of the ignition switch status.
The chime warning system provides an audible indication to the vehicle operator or occupants under the following conditions:
- Door Ajar Chime
- The Instrument Cluster (IC) (also known as the Common Instrument Cluster/CIC) will sound an audible chime when the key is in the ignition and the driver side front door is open. This provides an alert that a door is open or only partially closed.
The audible chime will sound when the vehicle begins to move and a visual alert appears within the transmission range indicator of the IC indicating DOOR .
- Enhanced Seat Belt Reminder
- If all the following conditions are met after sixty seconds with the engine On, then the enhanced seat belt reminder feature will be activated.
- Driver seat belt is unbuckled for ten seconds or more.
- Vehicle speed is greater than five mph (8 km/h).
- The transmission gear selector position is not Reverse (R ) (except in manual transmission vehicles where the reverse position cannot be detected).
The seat belt indicator will periodically blink, accompanied by a continuous chime for approximately ninety-six seconds or until the driver seat belt is buckled. When the enhanced seat belt feature is not initiated or if the feature is disabled, the seat belt indicator will be turned On continuously until the driver seat belt is buckled.
In the same ignition cycle, if the seat belt is again unbuckled for more than ten seconds with the vehicle speed greater than five mph (8 km/h), the enhanced seat belt reminder feature will again be initiated.
The enhanced seat belt reminder feature is customer programmable and can be enabled or disabled using a diagnostic scan tool, or by the customer completing a specific sequence of steps as follows:
- With the ignition status not Run or Start, buckle the driver seat belt.
- Transition the ignition status to the Run or Start and wait for the seat belt reminder check to be completed.
- Unbuckle and then re-buckle the driver seat belt causing the indicator to go On and Off three or more times ending with the seat belt buckled.
- Return the ignition to any non-Run or non-Start status. The feature will toggle from the current status and a confirmation chime will sound indicating to the customer that the proper sequence to enable or disable the feature has been successfully completed.
- Exterior Lamps Left On - An audible chime tone that indicates the exterior lamps were left On.
- Fasten Seat Belts - At power up, the IC will conduct a seat belt lamp bulb check. If the driver side seat belt buckle is unbuckled during the bulb check, an accompanying chime will sound within the duration of the bulb check.
- Key Left In Ignition - An audible chime tone that indicates the key was left in ignition.
- Single Warning Chime - After a bulb check at power-up, if any of the following indicators are still activated, the IC will sound a single chime tone. ABS, Air Bag, Check Engine, Charging System, Engine Temperature, Low Fuel (after 10 seconds for accurate fuel information), and Brake (if speed is greater than 2 mph).
