The single CD player and the CD changer*
are Class 1 laser products. There is a danger
of invisible laser radiation if the housing is
opened or damaged.
Do not open the housing. The single CD
player and the CD changer* do not contain
any parts that can be serviced by the user.
For safety reasons, have any service work
which may be necessary performed only by
qualified personnel.
Warning!

In order to avoid distraction which could
lead to an accident, the driver should insert
CDs with the vehicle at a standstill and oper-
ate the audio system only if permitted by

not even with a CD adapter. Attempting to
play CDs with an eight cm diameter or
playing such CDs with an adapter may
cause damage to the CD drive. Such dam-
age is not covered by the Mercedes-Benz
Limited Warranty.
Should excessively high or low tempera-
tures occur while in CD changer mode*, CD TEMP
will appear in the display, and the
CD will be muted until the temperature has
reached an acceptable level for the system
to continue operation.
The single CD player and the CD changer*
play audio CDs. Tips on handling CDs


Handle CDs carefully to prevent inter-
ference during playback.


Avoid scratches, fingerprints and dust
on the CDs.


Do not write on CDs or apply any labels
or other material to them.


Clean CDs from time to time with a
commercially available cleaning cloth.
Never wipe the CD in a circular motion;
instead, wipe it in a straight line start-
ing in the center and moving outward.
Do not use solvents, anti-static sprays,
etc. for cleaning.


Replace the CD in its case after use.


Protect CDs from heat and direct sun-
light.
!If you affix stickers to the CDs, they can
become warped due to the heat that
develops in the CD drive or CD chang-
er.
In certain situations, the CDs can then
no longer be ejected and cause dam-
age to the drive. Such damage is not
covered by the Mercedes-Benz Limited
Warranty.!Your CD drive or CD changer has been
designed to play CDs which corre-
spond to the EN 60908 standard. You
can therefore only use CDs with a max-
imum thickness of 1.3 mm.
If you insert thicker data carriers, e.g.
ones that have data on both sides (one
side with DVD data, the other side with
audio data), they cannot be ejected and
will damage the drive.
