Playing a Compact Disc

Insert a disc partway into the slot, label side up. The player will pull it in. The compact disc symbol will appear on the display. If the ignition and the radio are on, the disc will begin playing.

The integral CD player can play the smaller 8 cm single discs with an adapter ring. Full-size compact discs and the smaller discs are loaded in the same manner.

If playing a CD-R the sound quality may be reduced due to CD-R quality, the method of recording, the quality of the music that has been recorded and the way the CD-R has been handled. You may experience an increase in skipping, difficulty in finding tracks and/or difficulty in loading and ejecting. If these problems occur try a known good CD.
