Playing an MP3/WMA CD-R or CD-RW Disc If you have a radio with a six-disc CD player, it has the capability of playing an MP3/WMA CD-R or CD-RW disc. For more information on how to play an MP3/WMA CD-R or CD-RW disc, see "Using an MP3" in the index. 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/retailer. If the radio displays an error message, write it down and provide it to your dealer/retailer when reporting the problem. CD Messages CHECK DISC: If this message displays and/or 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 could have been a problem while burning the CD. • The label could be caught in the CD player. Using the Auxiliary Input Jack Your radio system has an auxiliary input jack located on the lower right side of the faceplate. This is not an audio output; do not plug the headphone set into the front auxiliary input jack. You can however, connect an external audio device such as an iPod, laptop computer, MP3 player, CD changer, or cassette tape player, etc. to the auxiliary input jack for use as another source for audio listening. Drivers are encouraged to set up any auxiliary device while the vehicle is in PARK (P). See Defensive Driving on page 330 for more information on driver distraction. 277
