Gracenote® media database
iThis function is only available in audio CD
mode and when operated from the built-in
hard disk.
The COMAND hard disk contains a version of
the Gracenote® Media Database, Emeryville,
California, USA. Some audio displays show
the company logo in the lower right to
indicate availability.
A large number of audio discs contain text
information. COMAND uses this information
to display the artist, the album name and the
track name.
When the audio disc does not contain text
information, COMAND can recognize
unknown audio tracks using the Gracenote®
Media Database. The respective information
must be stored in the Gracenote® Media
Database and the function Gracenote
Media Database in the CD submenu must be
activated.
COMAND will then display the accompanying
data such as artist, album name and track
name.
When COMAND accesses the Gracenote®
Media Database while reading an audio disc,
the following message appears:

Audio AUX and video AUX
You can play back external audio or video
sources via the systems installed in your
vehicle.
The sockets for external audio and video
sources (AUX) are located
R in the glove box (COMAND)
R on the CD/DVD drive in the rear passenger
compartment
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

Rear Seat Entertainment SystemGObserve Safety notes, see page 76.GWarning!
The driver should not wear a Rear Seat
Entertainment headphone while operating the
vehicle under any circumstances. The use of
a headphone while driving the vehicle could
drastically impair the ability to react to audible
traffic conditions (e.g. emergency sirens from
police/fire/ambulance, another car’s horn,
etc.).
GWarning!
When not in use, headphones or external
video sources should be stored in a safe
location (e.g. one of the vehicle’s storage
compartments) so that they are not loose
within the passenger compartment during
braking, vehicle maneuvers or a traffic
accident. Objects moving within the
passenger compartment could cause serious
personal injury to vehicle occupants.
GWarning!
Due to a potential choking hazard, wired
headphone usage by children should only
occur with adult supervision.
You can operate the Rear Seat Entertainment
System via the remote controls ( Y page 81)
that come with the vehicle.
The playback of audio and video sources with
the Rear Seat Entertainment System is
identical to playback with the COMAND to a
large extent.
The COMAND and the Rear Seat
Entertainment System can be operated
simultaneously almost independent of each
other. However, some menus may cause
conflicts when the systems are used by
multiple users. Conflicts can occur between
the rear screens as well as COMAND and the
Rear Seat Entertainment System.
Remote controls for Rear Seat
Entertainment System
The Rear Seat Entertainment System
contains two remote controls for the rear
passenger compartment.
For information on using the remote controls,
see ( Y page 81).
Headphones for Rear Seat
Entertainment System
The Rear Seat Entertainment System
contains two headphones for the rear
passenger compartment.
For information on using the headphones, see
( Y page 82).
