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 could have been a
problem while burning the CD.
The label could 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 the radio
displays an error message, write it
down and provide it to your dealer
when reporting the problem.
Do not add any label to a disc.
It could get caught in the CD or
DVD player. If a disc is recorded on
a personal computer and a
description label is needed, try
labeling the top of the recorded disc
with a marking pen.
The use of CD/DVD lens cleaners is
not advised, due to the risk of
contaminating the lens of the optics
with lubricants internal to the CD
and DVD player mechanism.
If an error displays, see CD

carefully. Store CD-Rs or CD-RWs
