Operating safety
Warning! G
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.
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
Any alterations made to electronic
components can cause malfunctions.
The radio, amplifier, CD changer*, satellite
radio*, telephone* and voice control
system* are interconnected. When one of
the components is not operational or has
not been removed/replaced properly, the
function of other components may be
impaired.
This condition might seriously impair the
operating safety of your vehicle.
We recommend that you have any service
work on electronic components carried out
by an authorized Mercedes-Benz Center.

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.

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
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

Tips on handling CDs
앫 Handle CDs carefully to prevent
interference during playback.
앫 Avoid scratches, fingerprints and dust
on the CDs.
앫 Do not write on CDs or apply any labels
or other material to them.
앫 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.
앫 Replace the CD in its case after use.
앫 Protect CDs from heat and direct
sunlight.
!
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.
