CD DOOR OPEN: The CD changer door is open. Completely close the door to restore normal operation. If the CD is not playing correctly, for any other reason, try a known good CD. If any error occurs repeatedly or if an error cannot be corrected, contact your dealer. If the radio displays an error message, write it down and provide it to your dealer when reporting the problem. Audio Steering Wheel Controls Theft-Deterrent Feature THEFTLOCK® is designed to discourage theft of your vehicle's radio. The feature works automatically by learning a portion of the Vehicle Identification Number (VIN). If the radio is moved to a different vehicle, it will not operate and LOCKED will appear on the display. With THEFTLOCK® activated, the radio will not operate if stolen. If your vehicle has this feature, some audio controls can be adjusted at the steering wheel. They include the following: PRESET: Press this button to scan the stations that are programmed on the radio preset pushbuttons. The radio will go to a preset station, play for a few seconds, then go to the next station. Press this button again to stop scanning. The radio will only scan preset stations with a strong signal that are in the selected band. When a cassette tape is playing, press this button to play the other side of the tape. 3-99
