The DIC comes on when the ignition is on. The DIC has different modes which can be accessed by pressing the DIC buttons. The button functions are detailed in the following.

Information Modes

(Information): Press this button to scroll through the following vehicle information modes:

Outside Air Temperature and Odometer

Press the information button until the outside air temperature and the odometer are displayed. This mode shows the temperature outside of the vehicle in either degrees Fahrenheit (°F) or degrees Celsius (°C) and the total distance the vehicle has been driven in either miles (mi) or kilometers (km). The outside air temperature will appear on the left side of the DIC display and the odometer will appear on the right side of the display.

To change the DIC display to English or metric units, see "UNITS" under DIC Vehicle Personalization .

TRIP A or TRIP B

Press the information button until TRIP A or TRIP B is displayed. 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.

Each trip odometer can be reset to zero separately by pressing and holding the reset button for a few seconds while the desired trip odometer is displayed.

FUEL RANGE

Press the information button until FUEL RANGE is displayed. 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 will display.

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.

ECON (Economy)

Press the information button until ECON is displayed. 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.

Press and hold the reset button while ECON is displayed to reset the average fuel economy. Average fuel economy will then be calculated starting from that point. If the average fuel economy is not reset, it will be continually updated each time you drive.

AV (Average) SPEED

Press the information button until AV SPEED is displayed. This mode shows the vehicle's average speed in miles per hour (mph) or kilometers per hour (km/h).

Press and hold the reset button while AV SPEED is displayed to reset the average vehicle speed.

OIL LIFE

Press the information button until OIL LIFE is displayed. The engine oil life system shows an estimate of the 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.

In addition to the engine oil life system monitoring the oil life, additional maintenance is recommended in the Maintenance Schedule in this manual. See Engine Oil and Scheduled Maintenance .

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 .

COOLANT

Press the information button until COOLANT is displayed. This mode shows the temperature of the engine coolant in either degrees Fahrenheit (°F) or degrees Celsius (°C).

BOOST (Turbo Only)

If your vehicle has this feature, press the information button until BOOST is displayed. This mode shows a graphic that indicates the amount of boost the engine is receiving in either pounds per square inch (psi) or kilopascals (kPa).
