The driver information center (DIC) consists of a multi-function electronic display placed in the overhead console. The DIC displays the following information:

    • The vehicle fuel information
    • The outside temperature
    • The direction the vehicle is facing

The display parameters are cycled, changed, and acknowledged using the following 2 DIC buttons mounted at the side of the driver information center:

US/MET: Allows the display to switch between English and Metric units.

MODE: Used to toggle between OFF, COMP/TEMP and TRIP.

COMP/TEMP

COMP: In the Compass Mode, one of eight compass readings (N, NE, E, SE, S, SW, W, and NW) will be displayed to indicate the direction the vehicle is facing.

TEMP: In the Temperature Mode, the outside air temperature is displayed in either °C or °F. If the outside air temperature is below 3°C (37°F), the display will toggle between ICE and the current outside air temperature in 8 second increments.

AVG ECON: The DIC displays the average fuel economy since the last reset.

AVG SPEED: The DIC displays the average speed since the last reset.

FUEL USED: The DIC displays the amount of fuel used since the last reset.

INST ECON: The DIC displays the instantaneous fuel economy since the last second of driving.
