General notes
The system may not be able to play audio
CDs with copy protection.
Playing copied CDs may cause
malfunctions during playback.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.
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
vehicle is covering 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 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
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.
!Do 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.
