MODE

The MODE button is used in order to toggle through the following DIC modes:

RESET

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

SELECT

The SELECT button is used in order to select a DIC mode.

TRIP RESET

The TRIP RESET button is used in order to reset the trip odometer to zero.

The vehicle data parameters are available to the driver when the ignition is ON. The driver navigates through the various parameters displayed on the driver information center (DIC) using the MODE button. Some parameters can be reset using the RESET button.

Some parameters require information from other modules via class 2 serial data messages. If the instrument cluster (IPC) has not received data for a parameter when the time has come to display the parameter, the IPC will blank the data on the DIC. If the IPC has determined that a class 2 communication failure with one of the modules exists when the time has come to display the parameter, the IPC will display dashes on the DIC.

The vehicle data parameters are displayed in the following order:

1. Average fuel economy
2. Instantaneous fuel economy
3. Fuel range
4. Fuel used
5. GM oil life system
6. Battery voltage (with Boost Gauge)
7. Tire pressure monitor

Average Fuel Economy

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

The XX.X represents the calculated average fuel economy value. The units of the display correspond to the current IPC setting. The average fuel economy is reset by pressing the RESET button for greater than 5 seconds while the AVG FUEL ECONOMY 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. The IPC uses the distance information calculated for the odometer display. The instantaneous fuel economy parameter is displayed on the DIC in one of the following formats:

The XX represents the calculated instantaneous fuel economy value. The units of the display correspond to the current IPC setting. 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, fuel used, and fuel capacity. The IPC uses the distance information calculated for the odometer display. The fuel range parameter is displayed on the DIC in one of the following formats:

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

Fuel Used

The fuel used parameter is the amount of fuel that has been used since the last parameter reset. The IPC receives a class 2 message from the PCM indicating the fuel used. The fuel used parameter is displayed on the DIC in one of the following formats:

The XXX.X represents the calculated fuel used value. The units of the display correspond to the current IPC setting. The fuel used is reset by pressing the RESET button for greater than 5 seconds while the FUEL USED is displayed. The DIC displays a range from 0.0 to 99.9 GAL in the English mode and from 0.0 to 999.9 L for the metric mode.

Engine Oil Life

The engine 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 XXX represents the calculated engine oil life value. The value ranges between 100% and 0%. The oil life is reset to 100% by pressing the RESET button for greater than 5 seconds while the OIL LIFE is displayed.

Battery Voltage (with Boost Gauge)

The battery voltage is displayed on the DIC as determined by the dash integration module (DIM). The IPC receives a class 2 message from the DIM indicating the system voltage. If the IPC detects a loss of class 2 communications with the DIM, the IPC uses the ignition 3 voltage circuit in order to display the voltage. The voltage is displayed on the DIC in one of the following formats:

The XX.X represents the battery voltage value. The battery voltage parameter cannot be reset by the driver. The battery voltage value ranges between 9.0 and 18.0 volts. If the voltage is less than 10.5 volts, the DIC displays LOW. If the voltage is greater than 16.2 volts, the DIC displays HIGH.

Tire Pressure Monitor

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:

If the IPC receives a class 2 message from the EBCM indicating a low tire pressure condition, the DIC displays LOW. The tire pressure monitoring system is reset by pressing the RESET button for greater than 5 seconds while the TIRE PRESSURE is displayed.

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).
