7-18 . Infotainment System Care of CDs and DVDs If playing a CD-R, the sound quality can be reduced due to CD-R or CD-RW quality, the method of recording, the quality of the music that has been recorded, and the way the CD-R or CD-RW has been handled. Handle them carefully. Store CD-R(s) or CD-RW(s) in their original cases or other protective cases and away from direct sunlight and dust. The CD or DVD player scans the bottom surface of the disc. If the surface of a CD is damaged, such as cracked, broken, or scratched, the CD does not play properly or not at all. Do not touch the bottom side of a CD while handling it; this could damage the surface. Pick up CDs by grasping the outer edges or the edge of the hole and the outer edge. If the surface of a CD is soiled, take a soft, lint‐free cloth or dampen a clean, soft cloth in a mild, neutral detergent solution mixed with water, and clean it. Make sure the wiping process starts from the center to the edge. Care of the CD and DVD Player Do not add any label to a CD; it could get caught in the CD or DVD 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. If an auxiliary input device is not connected, and a disc is in both the DVD slot and the CD slot, the DVD/CD/AUX button only cycles between the two sources and does not indicate "No Aux Input Device." If a front auxiliary input device is connected, the DVD/CD/AUX button cycles through all available options. . If a disc is inserted into the top DVD slot, the rear seat operator can turn on the video screen and use the remote control to only navigate the CD tracks through the remote control. See Auxiliary Devices on page 7‑38 or "Audio/Video (A/V) Jacks" under, Rear Seat Entertainment (RSE) System on page 7‑40 for more information.
