Playing an MP3 CD-R Disc
Your vehicle's radio system may have the MP3
feature. If it has this feature, it is capable of playing
an MP3 CD-R disc. For more information on
how to play an MP3 CD-R disc, see Using an MP3
on page 271 later in this section.
CD Messages
CHECK CD: If this message appears on the
display 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.
•
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.
•
The format of the CD is not compatible. See
Using an MP3 on page 271 later in this
section.
•
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.
