General information about Bluetooth®
Bluetooth® technology is the standard for
short-range wireless technologies, suitable
for transmitting voice and data. It is possible
to connect Bluetooth® devices wirelessly.
Bluetooth® can be used to exchange vCards
or to make calls using a hands-free device.
Bluetooth® technology uses the freely
available ISM (Industrial Scientific Medical)
wave band that works at 2.45 GHz.
Bluetooth® works within a range of up to 33 ft
(10 m).
Activate or deactivate Bluetooth®
Xi Q System Q Activate
Bluetooth.
You have activated or deactivated
Bluetooth®. A checkmark O appears when
Bluetooth® is activated.

iYou can reset the audio system back to
its factory settings. In this case, all personal
data (e.g. address book entries, call lists,
paired mobile phones, and presets) are
deleted. We recommend that you reset the
values before selling your vehicle.

i The components and operating principles
of the audio system can be found on
( Y page 137) and ( Y page 143).
The audio system is fitted with either a single
CD drive or a CD changer.
The single CD player and 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 precautionsGWarning!
The single CD player and the CD changer are
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 single CD player and the CD changer do
not contain any parts that you are able to
maintain yourself. For safety reasons, all
maintenance work must be carried out by
qualified technicians.
GWarning!
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 single CD player and/or 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 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 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
drive.
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 drive. 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 single CD player and 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.
