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 your radio displays an
error message, write it down and provide it to your
dealer when reporting the problem.
Theft-Deterrent Feature
THEFTLOCK ® is designed to discourage theft of your
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, your radio will not operate
if stolen.
