Safety precautions General notes
Warning!G
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.
Warning!G
Only carry out the following when the vehi-
cle is stationary:

Inserting a disc

Ejecting a disc
There is a risk of accident by being distract-
ed from road and traffic conditions if you
load a CD while the vehicle is in motion.
Bear in mind that at a speed of just 30 mph
(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
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 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.

pose.
