The use of CD/DVD lens cleaners
is not advised, due to the risk of
contaminating the lens of the optics
with lubricants internal to the CD
and DVD player mechanism.
Notice:If a label is added to a
CD, more than one CD is inserted
into the slot at a time, or an
attempt is made to play scratched
or damaged CDs, the CD player
could be damaged. While using
the CD player, use only CDs in
good condition without any label,
load one CD at a time, and keep
the CD player and the loading slot
free of foreign materials, liquids,
and debris.
If an error displays, see “CD
Messages” later in this section.
Care of CDs and DVDs
If playing a CD-R or CD-RW, 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-Rs or CD-RWs 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 disc is
damaged, such as cracked, broken,
or scratched, the disc does not play
properly or not at all. Do not touch
the bottom side of a disc while
handling it; this could damage the
surface. Pick up discs by grasping
the outer edges or the edge of the
hole and the outer edge.
If the surface of a disc is soiled,
clean it with a soft, lint‐free cloth or
dampen a clean, soft cloth in a mild,
neutral detergent solution mixed
with water. Make sure the wiping
process starts from the center to
the edge.Audio Output
Only one audio source can be heard
through the speakers at one time.
An audio source is defined as DVD
slot, CD slot, XM, FM‐AM, front
auxiliary jack, USB port, or rear

jack, USB port, or the rear auxiliary
jack, the front seat passengers are
able to listen to playback from
this source through the vehicle
speakers. See “Using the Auxiliary
Input Jack” inAuxiliary Devices on
page 7‑32, or “Audio/Video (A/V)
