Warning!G
Only operate an external audio source (AUX)
when the vehicle is stationary. There is a risk
of accident by being distracted from road
and traffic conditions if you operate an ex-
ternal audio source (AUX) while the vehicle
is in motion.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your car is
covering a distance of 44 feet
(approximately 14 m) every second.
Warning!G
Due to the different volumes of the external
audio sources, system messages (e.g. traffic
and navigation announcements) may be
much louder. You may need to disable these
system messages or adjust the volume of
these messages manually.
iPlease refer to the relevant manufacturers
operating instruction for the external audio
source device.
iThe volume of external audio sources is ex-
tremely variable. It is possible that a device con-
nected as an external audio source will sound
quieter or louder in the vehicle or that the usual
maximum volume cannot be achieved. On cer-
tain devices the volume can be set separately. In
this case, start at a moderate volume and in-
crease it slowly. In this way, you can determine
whether the system is capable of playback with-
out distortion, even at high volume.

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.Do not use CDs with an eight cm diameter,
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 ERROR 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 play audio CDs, the
CD changer* can play audio CDs as well as
CDs with MP3 files.
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 necessary ser-
vice work 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 oper-
ate 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.
!If you affix stickers to the CDs, they can be-
come 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 de-
signed 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.
