The Audi Driver Information System (or DIS) is a system that displays information in the center of the instrument cluster where it can be checked quickly and easily. Using buttons mounted on the windshield wiper lever the driver can select a wide variety of information. The system can display information about an open door or trunk, radio station, outside temperature (and ice warning indicator when the temperature drops below 41 degrees Fahrenheit), speed warning, gear selector position (on vehicles with automatic transmissions), names and telephone numbers from your phone book, and navigation directions. The system can also show info from the on-board computer including instant and average fuel economy, range, travel time, and average speed. The Auto Check Control notifies you if there is a problem with the brake or light systems, coolant level or engine temperature, oil pressure, fuel level, windshield washer fluid, battery voltage, or tire pressure.
