CD Messages
CHECK CD: If this message appears on the radio
display, it could be for one of the following reasons:
• It is very hot. When the temperature returns to
normal, the CD should play.
• You are driving on a very rough road. When the
road becomes smooth, 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 may have been a problem while burning
the CD.
• The label may be 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 your radio displays an
error message, write it down and provide it to your
dealer when reporting the problem.
