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 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 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.

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.
!
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.
