The DIC uses the following switches in order to navigate through the information displays:

ENG/MET

The ENG/MET button is used in order to change the IPC, the DIC, and the HUD displays between English and metric units. The km/h indicator or the MPH indicator illuminate in the IPC and the HUD accordingly.

FUEL INFO

The FUEL INFO button is used in order to navigate through the fuel related displays. The FUEL INFO parameters are displayed in the following order:

Average Fuel Economy

The average fuel economy is a function of the distance travelled divided by the fuel used since the average fuel economy parameter was last reset. The IPC receives a class 2 message from the PCM indicating the fuel used, and the IPC uses the distance information calculated for the odometer display for the values in the equation. The average fuel economy parameter is displayed on the DIC in one of the following formats:

The ##.# represent the calculated average fuel economy value. The units of the display correspond to the current IPC setting (English/metric). The average fuel economy is reset by pressing the RESET button for greater than 5 seconds while the average fuel economy message is displayed. The DIC displays 0.0 MPG for the English mode and 99.9 L/100km for the metric mode when the parameter is reset.

Instantaneous Fuel Economy

The instantaneous fuel economy is a function of distance divided by fuel used over a short period of time. The IPC receives a class 2 message from the PCM indicating the fuel used, and the IPC uses the distance information calculated for the odometer display for the values in the equation. The instantaneous fuel economy parameter is displayed on the DIC in one of the following formats:

The ## represent the calculated instantaneous fuel economy value. The units of the display correspond to the current IPC setting (English/metric). The instantaneous fuel economy cannot be reset by the driver.

Fuel Range

The fuel range is the estimated distance that the vehicle can travel without refueling. This calculation is based on the current fuel economy and fuel level conditions from the previous 40 km (25 miles) of driving. The IPC receives class 2 messages from the PCM indicating the fuel level percent and the fuel capacity, and the IPC uses the distance information calculated for the odometer display for the values in the equation. The fuel range parameter is displayed on the DIC in one of the following formats:

The ### represent the calculated fuel range value. The units of the display correspond to the current IPC setting (English/metric). The fuel range cannot be reset by the driver. When the fuel range is less than 64 km (40 miles) the DIC displays LOW RANGE.

GAGE INFO

The GAGE INFO button is used in order to navigate through the gauge related displays. The GAGE INFO parameters are displayed in the following order:

1. Oil pressure
2. Coolant temperature
3. Battery voltage
4. GM oil life index
5. Tire pressure status

Oil Pressure

The PCM monitors the oil pressure sensor and sends class 2 messages to the IPC indicating the oil pressure. The oil pressure parameter is displayed on the DIC in one of the following formats:

The ### represent the oil pressure value as determined by the PCM. The units of the display correspond to the current IPC setting (English/metric). The DIC displays LOW instead of NORMAL when the PCM sends a class 2 message to the IPC requesting illumination of the engine oil pressure indicator in the cluster. The IPC displays -- -- -- instead of an oil pressure value when an engine oil pressure sensor circuit malfunction has been detected by the PCM. The oil pressure cannot be reset by the driver.

Coolant Temperature

The PCM monitors the coolant temperature sensor and sends class 2 messages to the IPC indicating the coolant temperature. The coolant temperature parameter is displayed on the DIC in one of the following formats:

The ### represent the coolant temperature value as determined by the PCM. The units of the display correspond to the current IPC setting (English/metric). The IPC displays HOT instead of NORMAL when the IPC determines that a hot coolant temperature condition exists. The coolant temperature cannot be reset by the driver.

Battery Voltage

The DIM monitors the battery voltage and sends class 2 messages to the IPC indicating the battery voltage. The battery voltage parameter is displayed on the DIC in the following format:

BATTERY STATE

NORMAL ##.# V

The ##.# represent the battery voltage as determined by the DIM. The DIC displays LOW or HIGH instead of NORMAL when the IPC determines that a high or low battery voltage condition exists. The battery voltage cannot be reset by the driver.

GM Oil Life Index

The oil life parameter is calculated by the powertrain control module (PCM), and the information is provide to the IPC via class 2 serial data messages. The engine oil life parameter is displayed on the DIC in one of the following formats:

The ### represents the calculated engine oil life value. The value ranges between 100 and 0 percent. The oil life is reset to 100 percent by pressing the RESET button for greater than 5 seconds while the oil life index message is displayed.

Tire Pressure Status

The tire pressure parameter is displayed on the DIC as determined by the electronic brake control module (EBCM). The tire pressure is displayed on the DIC in one of the following formats:

The IPC displays LOW: CHECK TIRES when the IPC receives a class 2 message from the EBCM indicating a low tire pressure condition. The tire pressure monitoring system is reset by pressing the RESET button for greater than 5 seconds while the tire pressure status message is displayed.

ODO/TRIP

The ODO/TRIP button is used in order to display the season odometer and either of the two trip odometers. The odometer messages display in one of the following formats:

The ### represents the odometer value. The units of the display correspond to the current IPC setting (English/metric). The IPC uses the odometer display as the default. Each of the trip odometers is reset by pressing the RESET button while that trip odometer message is displayed.

RESET

The RESET button is used in conjunction with other buttons in order to reset system functions.

TRIP RESET

The TRIP RESET button is used in order to reset the trip odometer to zero on a base cluster.

Personalization features may be set for the vehicle or the driver. Vehicle features do not change with each driver. Specific drivers are recognized by the vehicle through the keyless entry transmitters, the memory buttons, or the driver information center (DIC).
