Driver Information Center (DIC)

Driver Information Center (DIC) Description and Operation

The driver information center (DIC) displays the DIC WOW for 5 seconds when it first powers up. If enabled through Customization menu, the DIC then returns to the last display status before no power condition.

There are 4 switch functions for the DIC.

* Trip/Fuel Info Switch
* Vehicle Information Switch
* Customization Switch.
* Set/Reset Switch

Trip/Fuel Info Switch

The Trip/Fuel switch is used to navigate between vehicle fuel information parameters. Cycle through the following vehicle parameters by successive pressing of the Trip/Fuel Info switch.

* Blank Display
* Average Fuel Economy (AFE)
* Average Vehicle Speed (AVE)
* Displacement on Demand (DOD)
* Fuel Range
* Instantaneous Fuel Economy (IFE)/ Displacement on Demand (DOD)
* Instantaneous Fuel Economy (IFE)
* Odometer
* Trip A
* Trip B

Vehicle Information Switch

Set/Reset Switch

Press the Set/Reset button in order to set or acknowledge any of the switch menu options.

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 IPC. The value of this mode is retained during ignition OFF and can be changed between English units and metric units by selecting from the English/Metric menu.

Average Speed

Average speed is calculated using the equation: Average Speed = AVS Distance/AVS Time

* Distance = The accumulated distance travelled since the last reset of this value
* Ignition On = The accumulated ignition on time since the last reset of this value

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 = Range Distance/Range Fuel Used.

* Range Distance = The accumulated distance travelled since the last reset of this value.
* Fuel Used = The accumulated fuel delivered since the last reset of this value

The ECM sends the fuel range value to the instrument panel cluster (IPC). The fuel range value is retained during ignition OFF and can be changed between English and Metric units by accessing the English/Metric menu. The Fuel Range display cannot be reset. LOW is displayed when fuel range is below a predetermined value.

Engine Oil Life Remaining

The engine control module (ECM) sends the engine oil life remaining percentage to the instrument panel cluster (IPC) via the serial data circuit. The instrument panel cluster receives a serial data message indicating the engine oil life remaining. The driver information center (DIC) displays the current percentage of the GM Oil Life System as determined by the ECM. When the oil life remaining percentage drops below 5 percent, the DIC displays CHANGE ENGINE OIL SOON. When the engine oil is changed, reset the GM Oil Life System. Refer to GM Oil Life System Resetting (Service and Repair).

Tire Pressure Monitor

The instrument panel cluster (IPC) receives a serial data message from the tire pressure monitoring (TPM) system for front and rear tire pressure data. The driver information center (DIC) will display the pressure for each of the front and rear tires. When a tire with low air pressure is present, the DIC displays XX TIRE PRESSURE LOW.

English/Metric Button

The English/Metric button is used to toggle between English and Metric unit systems and can be accessed through the Vehicle Info switch function.

Trip A/B

The trip odometer A or B can be accessed through the Trip/Fuel switch function.

Language

The DIC is capable of displaying in three languages:

* English
* French
* Spanish

A simultaneous press of the vehicle Information and customization switches for about 1 second provides a shortcut to change the language without understanding the currently displayed language. The Language settings may also be assessed through the customization switch.

Compass

The DIC displays the compass information on the right most 2 characters of the first DIC line when the compass is an option on the vehicle. When corresponding to the true north radial degrees, the compass displays the following directions
