DIC Operation and Displays The DIC comes on when the ignition is on. After a short delay the DIC will display the information that was last displayed before the engine was turned off. If a problem is detected, a warning message will appear on the display. Pressing the trip stem will acknowledge any warning or service messages. Pressing any of the DIC steering wheel buttons - trip information, fuel information, customization, or select button - will also acknowledge any warnings or service messages. Press this button to display the odometer, trip odometers, tire pressure, and timer. 3 (Trip Information): t (Fuel Information): Press this button to display the current range, fuel used, average fuel economy, and engine oil life. 4 (Customization): r (Select): Press this button to access the vehicle settings menu and customize the personal settings on your vehicle. You should take any message that appears on the display seriously and remember that clearing the message will only make the message disappear, not correct the problem. The DIC has different modes which can be accessed by pressing the four DIC buttons located on the steering wheel. These buttons are trip information, fuel information, customization, and select. The button functions are detailed in the following pages. Press this button to reset certain DIC functions and set your customization settings.
