CD Player Messages
CHECK DISC: If this message
displays and/or the CD ejects, it
could be for one of the following
reasons:
It is very hot. When the
temperature returns to normal,
the CD should play.
The road is very rough. 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 was a problem while
burning the CD.
The label is caught in the
CD player.
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. If the radio
displays an error message, write it
down and provide it to your dealer
when reporting the problem.

CD/DVD Player

Care of the CD and DVD Player
Do not add any label to a disc.
It could get caught in the CD or
DVD player. If a disc is recorded
on a personal computer and a
description label is needed, try
labeling the top of the recorded disc
with a marking pen.
Infotainment System
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.
If a label is added to a
CD, or 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.
