Radio Message THEFTLOCK: This message is displayed when the THEFTLOCK® system has been activated. Take the vehicle to the dealer for service. The CD player can play the smaller 3 inch (8 cm) single CDs with an adapter ring. Full-size CDs and the smaller CDs 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. There may be an increase in skipping, difficulty in finding tracks, and/or difficulty in loading and ejecting. If these problems occur, check the bottom surface of the CD. If the surface of the CD is damaged, such as cracked, broken, or scratched, the CD will not play properly. If the surface of the CD is soiled, see Care of Your CDs on page 285 for more information. If there is no apparent damage, try a known good CD. Do not add any label to a CD, it could get caught in the CD player. If a CD is recorded on a personal computer and a description label is needed, try labeling the top of the recorded CD with a marking pen instead. Radio Messages for XM™ Only See XM Radio Messages on page 279 later in this section for further detail. Using the Single CD Player Insert a CD partway into the slot, label side up. The player will pull it in. If the ignition and the radio are on the CD will begin playing. A CD may be loaded with the radio off but it will not start playing until the radio is on. If the ignition or radio is turned off with a CD in the player, it will stay in the player. When the ignition or radio is turned on, the CD will start to play where it stopped, if it was the last selected audio source. When the CD is inserted, CD will appear on the display. As each new track starts to play, the track number will appear on the display. 272
