The components and operating principles
of the audio system can be found on
(Y page 112) and ( Y page 116).
The audio system is fitted with a CD changer.
The CD changer can play audio CDs as well
as CDs with MP3 or WMA files.
The available menu options will vary
depending on the equipment and the type of
CD.
Safety precautions G
Warning!
The CD changer is classified as a Class 1 laser
product.
You must not open the casing. There
is a risk of exposure to invisible laser radiation if you open the casing, or if the casing is faulty
or damaged.
The CD changer does not contain any parts
that you are able to maintain yourself. For
safety

reasons, all maintenance work must be
carried out by qualified technicians. G
Warning!
In order to avoid distraction which could lead
to an accident, the driver should insert or
eject CDs with the vehicle at a standstill and
operate

the audio system only if permitted by
road, weather and traffic conditions.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
General notes i
Audio CDs with copy protection are not
compatible

with the CD audio standard and
therefore may not be able to be played by
the CD changer. There may be playback
problems when playing copied discs.
There is a large variety of discs, disc-writing
software and writers available. This variety
means that there is no guarantee that the
system will be able to play discs that you
have written/copied yourself.
There may be playback problems if you use
CD-R or CD-RW type discs you have
compiled yourself with a storage capacity
of more than 700 MB. These CDs are not
compatible with currently applicable
standards.
! Do not affix stickers or labels to the CDs,
they can become warped due to the heat
that develops in the CD changer.
In certain situations, the CDs can then no
longer be ejected and cause damage to the
CD changer. Such damage is not covered
by the Mercedes-Benz Limited Warranty. Audio system

!
Your CD changer has been designed to
play CDs which correspond to the
IEC 60908 standard. You can therefore
only
use CDs with a maximum thickness of
1.3 mm.
If you insert thicker discs, 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 CD
changer.
Do not use CDs with a diameter of 8 cm.
Attempting to play CDs with a diameter of
8 cm or playing such CDs with an adapter may
cause damage to the CD changer. Such
damage is not covered by the Mercedes-Benz
Limited Warranty.
Only use round discs with a diameter of
12 cm.
Should excessively high or low temperatures
occur while in CD changer mode, a message
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.
Tips on handling CDs
R Only touch the CDs at the edges.
R Handle CDs carefully to prevent
interference during playback.
R Avoid scratches, fingerprints and dust on
the CDs.
R The CDs must only be labeled using pens
specially designed for this purpose.
R 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 starting in
the center and moving outward. Do not use
solvents, anti-static sprays, etc. for
cleaning.
R Replace the CD in its case after use.
R Protect CDs from heat and direct sunlight. Notes about MP3 mode The CD changer can play audio CDs as well
as CDs with MP3/WMA files.
i
Due to the branched data structure,
playback of the first track may be delayed
slightly.
Permissible media for MP3/WMA files
R CD-R
R CD-RW
Permissible file systems
R ISO9660/Joliet for CDs
Multisession CDs
For multisession CDs, the first session type
of the CD determines how the audio system
will process the CD.
For example, if the first session type is
according to the audio CD standard and the
second session type is according to the data
CD standard containing MP3/WMA tracks,
the audio system will treat the CD as a
conventional audio CD. This means that it is
only possible to access the audio CD tracks.
Access to the MP3/WMA tracks is not
possible.
Similarly,

if the first session type is according
to the data CD standard containing MP3/
WMA tracks and the second session type is
according to the audio CD standard, the audio
system will treat the CD as a data CD. This
means that it is only possible to access the
MP3/WMA tracks. Access to the audio CD
tracks is not possible.
File structure on a disc
When you create an MP3/WMA disc, the
MP3/WMA tracks can be organized in
folders.
A folder can also contain other folders.
A disc can contain a maximum of 255 folders.
A folder can contain a maximum of 255 tracks
and 255 subfolders. 132
