In order to avoid distraction which could
lead to an accident, the driver should enter
system settings with the vehicle at a
standstill and operate the system only when
road and traffic conditions permit. Always
pay full attention to traffic conditions first
before operating system controls while
driving.

properly, the function of other components
may be impaired.
This condition might seriously impair the
operating safety of your vehicle.

Safety precautions
General notes
The system may not be able to play audio
CDs with copy protection.
Playing copied CDs may cause
malfunctions during playback.Warning!
G
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!
G
In order to avoid distraction which could
lead to an accident, the driver should insert
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 car covers a
distance of 44 feet (approximately 14 m)
every second.iThe audio system plays both CD-Rs and
CD-RWs with audio data.
!If you affix stickers to the CDs, they can
become warped due to the heat that
develops in the CD drive or
CD changer.
In certain situations, the CDs can then
no longer be ejected and cause
damage 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
correspond to the EN 60908 standard.
You can therefore only use CDs with a
maximum 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.

220 Controls in detailAudio systemDo not use CDs with an 8 cm diameter, not
even with a CD adapter. Attempting to play
CDs with an 8 cm diameter or playing such
CDs with an adapter may cause damage to
the CD drive. Such damage 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
interference 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
sunlight.MP3
The CD changer* can play audio CDs as
well as CDs with MP3 files.
Information on MP3 data carriers
iCD media, CD burning software and
CD writers are available in great vari-
ety. Due to this variety, it cannot be
guaranteed that the CD changer will be
able to play every user-written CD.
The burning process can lead to data
errors and aging of the medium may re-
sult in data loss. Therefore, the
CD changer may be restricted in its
a bi li ty to p la y MP3 da ta c a rri ers ; it m a y
play them with reduced sound quality,
or it ma y not b e a bl e t o pla y them a t a ll .
Problems may be encountered during
playback of user-written CDs with a
storage capacity of more than 700 MB.
These CDs do not meet valid standards
as of this printing.
