For 1990-2009 cars

The driver information center (DIC) displays important vehicle information. The DIC also displays time, outside air temperature, date, audio system information, warning messages and trip computer (if equipped). The DIC serves as a gateway between the medium speed bus and the low speed bus. If the DIC is disconnected, communication with any other control module on the medium speed bus is not possible. The DIC is responsible for processing the information displayed through the serial data circuit. The DIC is also responsible for calculating and displaying the outside air temperature. The outside air temperature is transmitted to the DIC over the serial data circuit by the steering column control module (SCCM). The outside air temperature information is transmitted in degrees Celsius and the DIC is responsible for converting the outside air temperature to Fahrenheit. There are two DIC options available which are the base level DIC and the uplevel DIC. The type of data eg. trip computer and audio system information and how it is displayed depends on the level of the DIC and other available vehicle options.

### DIC Switch(es)

The functions, settings and the various system displays of the DIC can be accessed using the left thumbwheel switch located on the steering wheel or buttons on the audio system. Menu options can be selected using the left thumbwheel switch. Turn the thumbwheel switch DOWN to advance to the next menu, UP to return to the previous menu and PRESS to select the desired menu.

On some vehicles, the DIC display menus can be accessed from the multifunction switch located on the audio system. TURN the knob until the desired menu is displayed and highlighted. PRESS the knob to select the menu items available.

### System Settings

Pressing the SETTINGS button on the audio system is used to navigate through the system settings. Use the left arrow button on the audio system or the left thumbwheel switch on the steering wheel to navigate to different menu items and make the desired selection. The following system settings are available:

• | Date

• | Time

• | Language

• | Units

• | Ignition Logic

• | Contrast (Uplevel DIC only - adjusts the display contrast)

• | Day/Night (Up level DIC only - adjusts the display to match the lighting conditions)

### Trip Computer

The vehicle may be equipped with a trip computer displayed in the DIC. The trip computer provides vehicle information and driving data. To access the trip computer press the BC button on the audio system or press the left thumbwheel switch on the steering wheel. The following trip computer information can be displayed in the DIC:

• | Instantaneous Consumption

• | Average Consumption

• | Trip Consumption

• | Average Speed

• | Distance Travelled

• | Range

• | Stop Watch (Timer)

#### AVERAGE SPEED

This is the average vehicle speed recorded since the current ignition cycle or since the last reset of the value. Ignition time is measured from the time that the ignition is turned ON to the time when the ignition is turned OFF. The value of this mode is retained when the ignition is OFF. The average speed value can be reset to zero at any time and restarted. Average speed is displayed in miles per hour (mph) or kilometers per hour (km/h).

#### RANGE (FUEL)

This display indicates the estimated distance that the vehicle can travel under the current fuel economy and fuel level conditions since the last reset of the value. The DIC displays the approximate number of remaining miles or kilometers the vehicle can be driven without refueling.

#### AVERAGE CONSUMPTION

This is the vehicle average fuel economy calculated using the travel distance and fuel used information. It is the approximate average miles per gallon (mpg) or liters per 100kilometers (1/100km). The average consumption value can be reset to zero at any time and restarted.

#### INSTANTANEOUS CONSUMPTION

This display shows the current fuel economy at a particular moment and changes often as the driving conditions change. The display shows the instantaneous fuel economy in miles per gallon (mpg) or liters per 100kilometers (1/100km)

#### TRIP CONSUMPTION

This display shows the number of gallons or liters of fuel used since the last reset. This value can be reset to zero at any time and restarted.

#### DISTANCE TRAVELLED

This display shows the current distance travelled in miles or kilometers since the last reset. This value can be reset to zero at any time and restarted.

#### STOP WATCH (TIMER)

This display is used as a timer. Use the left thumbwheel switch or the audio system control to start, stop or reset the timer.

### DIC Warnings and Messages

Vehicle warnings and messages are displayed on the DIC to notify the driver of an important vehicle information. Multiple messages may appear one after another. The DIC displays information on some vehicle fluid levels, remote keyless entry (RKE) transmitter battery, theft-deterrent system (if equipped), the brake light switch, and important exterior lights, including wiring and fuses. Some messages may not require immediate action, but you can acknowledge that you received the message and clear them from the display by doing one of the following:

• | Press the OK button on the base level audio system.

• | Press the multifunction knob, if your vehicle has this feature, on the uplevel audio system.

• | Press the left thumbwheel, if your vehicle has this feature, on the steering wheel.

The following warnings and messages can be displayed:

• | BRAKE LIGHT CHECK

• | BRAKELIGHT SWITCH CHECK

• | COOLANT LEVEL CHECK

• | REMOTE CONTROL BATTERY CHECK

• | SAFEGUARD CHECK

• | WASHER FLUID LEVEL (BASE)

• | WASHING WATER LEVEL (UPLEVEL)

### Outside Air Temperature

The outside air temperature is read by the underhood electrical center (UEC) for the left outside air temperature. The outside air temperature is transmitted over serial data to the DIC for display via the steering column control module (SCCM). The DIC calculates and displays the outside temperature values.
