(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
iAudio CDs with copy protection are not

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 soft-
ware 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 copied yourself
with a storage capacity of more than 700 MB.
These CDs are not compatible with currently ap-
plicable standards.
!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 no longer be
ejected and can cause damage to the drive. Such
damage is not covered by the Mercedes-Benz
Limited Warranty.

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 operating guide
for operation of the external audio source.
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.
