The DIC comes on when the ignition is on. If your vehicle has the uplevel audio system, the time and outside temperature is shown on the first line of the display and the DIC information is shown on the second line of the display.

The DIC has different modes which can be accessed by pressing the DIC buttons. The button functions are detailed in the following section.

Information Modes

INFO (Information): Press this button to scroll through the vehicle information mode displays in the following order:

    • TRIP A
    • TRIP B
    • FUEL RANGE (Fuel Range Until Empty)
    • MPG (L/100 KM) AVG (Average Fuel Economy)
    • MPG (L/100 KM) INST (Instantaneous Fuel Economy)
    • AV SPEED (Average Vehicle Speed)
    • OIL LIFE (Engine Oil Life System)
    • Tire Pressure
TRIP A or TRIP B: Press the information button until TRIP A or TRIP B display. These modes show the current distance traveled since the last reset for each trip odometer in either miles (mi) or kilometers (km). Both odometers can be used at the same time. To reset the trip odometer to zero, press and hold the enter button for a few seconds while the desired trip odometer is displayed.

FUEL RANGE: Press the information button until FUEL RANGE displays. This mode shows the remaining distance you can drive without refueling in either miles (mi) or kilometers (km). It is based on fuel economy and the fuel remaining in the tank. When the fuel level is low, FUEL RANGE LOW displays. The fuel economy data used to determine fuel range is an average of recent driving conditions. As your driving conditions change, this data is gradually updated. The FUEL RANGE mode cannot be reset.

MPG (L/100 KM) AVG (Average): Press the information button until MPG (L/100 KM) AVG displays. This mode shows how many miles per gallon (mpg) or liters per 100 kilometers (L/100 km) your vehicle is getting based on current and past driving conditions. To reset the average fuel economy, press and hold the enter button while MPG (L/100 KM) AVG is displayed. Average fuel economy is then be calculated starting from that point. If the average fuel economy is not reset, it is continually updated each time you drive.

MPG (L/100 KM) INST (Instantaneous): Press the information button until MPG (L/100 KM) INST displays. This mode shows the current fuel economy at a particular moment and changes frequently as driving conditions change. This mode shows the instantaneous fuel economy in miles per gallon (mpg) or liters per 100 kilometers (L/100 km). Unlike average fuel economy, this screen cannot be reset.

AV (Average) SPEED: Press the information button until AV SPEED displays. This mode shows the vehicle's average speed in miles per hour (mph) or kilometers per hour (km/h). To reset the average vehicle speed, press and hold the enter button while AV SPEED is displayed.

OIL LIFE: Press the information button until OIL LIFE displays. The engine oil life system shows an estimate of the oil's remaining useful life. It shows 100% when the system is reset after an oil change. It alerts you to change the oil on a schedule consistent with your driving conditions. In addition to the engine oil life system monitoring the oil life, additional maintenance is recommended in the Maintenance Schedule in this manual. See Scheduled Maintenance and Engine Oil . Always reset the engine oil life system after an oil change. See "How to Reset the Engine Oil Life System" under Engine Oil Life System .

Tire Pressure: The pressure for each tire can be viewed in the DIC. The tire pressure is shown in either pounds per square inch (psi) or kilopascals (kPa). Press the information button until LF ## PSI (kPa) ## RF displays for the front tires. Press the information button again until LR ## PSI (kPa) ## RR displays for the rear tires. If a low tire pressure condition is detected by the system while driving, a message advising you to check the tire pressure appears in the display. See Inflation - Tire Pressure and DIC Warnings and Messages for more information.
