Safety notes
GWarning!
COMAND and the CD/DVD drive in the rear
are classified as Class 1 laser products. 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.
COMAND and the CD/DVD drive in the rear
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.
GWarning!
Only carry out the following when the vehicle
is stationary:
R Inserting a disc/device
R Ejecting a disc/device
There is a risk of accident by being distracted
from road and traffic conditions if you load a
disc/device 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 (approximately
14 m) every second.

Multisession CDs
For multisession CDs, the first session type
of the CD determines how COMAND will
process the CD.
For example, if the first session type is
according to the audio CD standard and the
second session type is according to the data
CD standard containing MP3/WMA tracks,
COMAND will treat the CD as a conventional
audio CD. This means that it is only possible
to access the audio CD tracks. Access to the
MP3/WMA tracks is not possible.
Similarly, if the first session type is according
to the data CD standard containing MP3/
WMA tracks and the second session type is
according to the audio CD standard,
COMAND will treat the CD as a data CD. This
means that it is only possible to access the
MP3/WMA tracks. Access to the audio CD
tracks is not possible.

R on the head restraints
i For operation of the external audio and
video sources, refer to the operating
instructions of the respective device. You
may have to adjust the proper video
standard on the external audio and video
source to ensure proper replay.
Do not leave external devices in the vehicle.
Proper function of the device could be
impaired due to excessive temperatures,
for example when exposing to direct
sunlight or when the outside temperature
is extremely low. Mercedes-Benz does not
assume liability for damage to external
devices.GWarning!
Operating an external audio source while the
vehicle is in motion will distract you. You may
not notice changing road and/or traffic
conditions which may cause an accident.
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.
For your safety and the safety of others, pull
over to a safe location and stop before
operating an external audio source.
GWarning!
Due to the different volumes of the external
audio sources, system messages of the
vehicle may be much louder. You may need to
disable these system messages or adjust the
volume of these messages manually.
i The volume of external audio sources is
extremely variable. It is possible that a
device connected as an external audio
source will sound quieter or louder in the
