Driver Information Center (DIC) MODE: Press this button to cycle through three modes of operation - off, compass/temperature and trip computer mode. Off: No driver information is displayed in this mode of operation. Compass/Temperature Mode: One of eight compass readings and the outside temperature are displayed. If the temperature is below 38°F (3°C), the temperature reading will toggle between displaying the outside temperature and the word ICE for two minutes. Trip Computer Mode: In the trip computer mode, pressing the MODE button cycles through the five displays. Press the MODE button after the last trip computer display to return the DIC to the OFF mode. See "Trip Computer" later in this section for more information. Your vehicle may have a DIC. If it does, the DIC will show information about the vehicle and the surroundings. E/M (English/Metric Button): You can change the display to a metric or English reading at any time by pressing E/M. Compass Variance Compass variance is the difference between magnetic north and geographic north. In some areas of the country, the difference is great enough to cause the compass to give false readings. If this occurs, the compass variance must be set. 3-52
