CD Messages
If the CD comes out, 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 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 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 GM dealer. If the
radio displays an error message, write it down and
provide it to your GM dealer when reporting the
problem.
