The driver information center (DIC) displays the driver identifier greeting for 5 seconds when it first powers up. If enabled through Options, the DIC then returns to the last display status before no power condition.
There are 4 buttons on the DIC.
Fuel
Press the Fuel button to display fuel information such as:
| • | Instantaneous Fuel Economy |
Fuel Range
This message indicates the estimated distance that the vehicle can travel under the current fuel economy and fuel level conditions since the last battery connection to the IPC. Fuel Range is calculated using the equation: Fuel Range = Distance Sum/Fuel
Sum.
| • | Distance Sum = The accumulated distance travelled since the last reset of this value. |
| • | Fuel Sum = The accumulated fuel delivered since the last reset of this value |
The ECM sends the fuel range value to the BCM. The instrument panel cluster (IPC) receives a serial data message from the BCM with the fuel information. The fuel range value is retained during ignition OFF and can be changed between English and Metric
units by pressing the English/Metric button on the driver information center (DIC) switch. The Fuel Range display cannot be reset. Whenever the calculated fuel range is less than 64 Km/h (39.8 miles) RANGE-LOW is displayed.
Average Fuel Economy
Average fuel economy is calculated using the equation: AFE = Distance/Fuel
| • | Distance = The accumulated distance travelled since the last reset of this value |
| • | Fuel = The accumulated fuel consumption since the last reset of this value |
The ECM sends the average fuel economy serial data message to the BCM. The instrument panel cluster (IPC) receives a serial data message from the BCM regarding fuel usage information. The value of this mode is retained during ignition OFF and can be changed
between English units and metric units by pressing the English/Metric button on the DIC switch. Press and hold the reset button on the driver information center (DIC) switch for 1 second in order to reset the AFE display.
Instantaneous Fuel Economy (IFE)
Instantaneous fuel economy (IFE) is calculated using the equation: IFE = Distance/Fuel.
| • | Distance = The accumulated distance travelled for the last 2 seconds |
| • | Fuel = The accumulated fuel delivered for the last 2 seconds |
The instrument panel cluster (IPC) receives a serial message from the BCM with fuel level information. The distance information is calculated by the IPC using the vehicle speed information from the ECM. These values are retained during ignition OFF and
can be changed between English and Metric units by pressing the English/Metric button on the driver information center (DIC) switch. The IFE display cannot be reset.
Gages
The gages button is used in order to scroll the following DIC menus:
| • | Transmission Fluid Temperature (Automatic Trans. Only) |
This display shows the oil pressure.
Press the gages button to display the oil pressure, such as:
Oil Temperature: This display shows the oil temperature.
Press the gages button again to display the oil temperature, such as:
| • | OIL TEMPERATURE 234°F or |
If the oil temperature is low, the display will show OIL TEMPERATURE LOW. If the oil temperature is high, the display will show OIL TEMPERATURE HIGH.
Coolant Temperature: This display shows the engine coolant temperature.
Press the gages button again to display the coolant temperature, such as:
| • | COOLANT TEMPERATURE 123°F or |
| • | COOLANT TEMPERATURE 51°C |
If the coolant temperature is low, the display will show COOLANT TEMPERATURE LOW. If the coolant temperature is high, the display will show COOLANT TEMPERATURE HIGH.
Transmission Fluid Temperature: If you have an automatic transmission vehicle, this display shows the automatic transmission fluid temperature.
Press the gages button again to display the automatic transmission fluid temperature, such as:
| • | TRANS FLUID TEMP 123°F or |
If the transmission fluid temperature is low, the display will show TRANS FLUID TEMP LOW. If the transmission fluid temperature is high, the display will show TRANS FLUID TEMP HIGH.
Battery Voltage: This display shows the current battery voltage.
Press the gages button again to display the battery voltage, such as:
BATTERY VOLTAGE 13.5 VOLTS
Tire Pressure: This display shows the tire pressure for each tire.
Press the gages button again to display the tire pressure for the front tires, such as:
| • | FRONT TIRE PRESSURES L 34 PSI R 33 PSI or |
| • | FRONT TIRE PRESSURES L 234 kPa R 228 kPa |
Press the gages button again to display the tire pressure for the rear tires, such as:
| • | REAR TIRE PRESSURES L 34 PSI R 33 PSI or |
| • | REAR TIRE PRESSURES L 234 kPa R 228 kPa |
TRIP
The TRIP button is used in order to scroll the following DIC menus
Odometer: The odometer shows how far your vehicle has been driven in either miles or kilometers. Press the TRIP button to display odometer readings, such as:
The odometer can be displayed by turning on the parking lamps.
Trip Odometers: There are two trip odometers. Press the TRIP button to display TRIP ODOMETER A readings and press the button again to display TRIP ODOMETER B readings, such as:
| • | TRIP ODOMETER A 130.5 MI or |
| • | TRIP ODOMETER A 209.9 km |
| • | TRIP ODOMETER B 300.5 MI or |
| • | TRIP ODOMETER B 483.5 km |
Both of the trip odometers can be used simultaneously. TRIP A could be used to track the distance to a destination. TRIP B could be used to track maintenance periods. The trip odometers can be reset by pressing the RESET button on the DIC.
There is also a miles since last ignition feature that displays the number of miles (kilometers) driven since you last started the vehicle. Press and hold the RESET button for three seconds, then release it. The miles (kilometers) since the last ignition
cycle will be set into the trip odometer.
Elapsed Timer: Press the TRIP button until ELAPSED TIMER is displayed, such as ELAPSED TIMER .00.
When the ignition is in on, the DIC can be used as a stopwatch. The display can show hours, minutes and seconds. The elapsed time indicator will record up to 23 hours, 59 minutes and 59 seconds, then it will reset to zero and continue
counting. The display appears as ELAPSED TIMER .00 in the elapsed time function.
You can start or stop the elapsed time by pressing the RESET button. To reset the elapsed time to zero, press the RESET button for three seconds while the timer is displayed.
Pressing and holding the RESET button for at least 10 seconds will reset the timer display to the time since last ignition cycle.
Average Speed: Press the TRIP button until the average speed is displayed, such as:
| • | AVERAGE SPEED 62 MPH or |
Press and hold the RESET button to reset to 0.0 mph (km/h).
Engine Oil Life: Press the TRIP button until the engine oil life is displayed, such as OIL LIFE REMAINING 89%.
This is an estimate of the engine oil's remaining useful life. It will show 100% when the system is reset after an oil change. It will alert you to change your oil on a schedule consistent with your driving conditions. When the remaining oil life
is low, the system will alert you with the message CHANGE ENGINE OIL.
Reset the engine oil life system yourself after each oil change. Refer to
GM Oil Life System Resetting.
OPTION
The OPTION button allows you to access the PERSONAL OPTIONS menu and customize the personalization settings on your vehicle. Refer to the owners manual for the vehicle personalization settings.
RESET
The RESET button, used along with other buttons resets system functions and turn off or acknowledge messages on the DIC.
Press the Reset button on the driver information center (DIC) switch for 1 second in order to acknowledge and/or reset the current DIC display. For engine oil life reset, it takes at least 3 seconds.
