CD Player Messages
CHECK DISC: If this message displays and/or the CD ejects, it could be for one of the following reasons:
• It is very hot. When the temperature returns to normal, the CD should play.
• The road is very rough. When the road becomes smoother, the CD should play.
• The CD is dirty, scratched, wet, or upside down.
• The air is very humid. If so, wait about an hour and try again.
• There was a problem while burning the CD.
• The label is caught in the CD player.
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.
