make sure that there is no danger of anyone
being harmed by the opening/closing
procedure.
The sliding sunroof is equipped with
automatic operation and the anti-entrapment
feature. If the movement of the sliding sunroof
is blocked during the closing procedure, the
sliding sunroof will stop and open slightly.

event of an accident, the glass may shatter.
This may result in an opening in the roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury for
occupants wearing their seat belts properly,
as entire body parts or portions of them may
protrude from the passenger compartment.

of snow and ice. Otherwise, malfunctions
may occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could

sliding sunroof is closed when you leave the
vehicle. The vehicle electronics can be
damaged if water enters the vehicle
interior.
i Resonance noises can occur in addition

Surround sound
General information
If your vehicle is equipped with the harman/
kardon ®
Logic 7 ®
surround sound system,
you can provide the optimum sound
experience for every passenger.
The harman/kardon ®
Logic7 ®
surround
sound system is available for the following
operating modes:
R radio (FM only)
R satellite radio
R audio CD
R audio DVD (MLP™, dts™, PCM and
Dolby ®
Digital audio formats)
R MP3
R Media Interface
R video DVD (PCM, dts™ and Dolby ®
Digital
audio formats)
R AUX
Because some DVDs contain both stereo and
multichannel audio formats, it may be
necessary to set the audio format
( Y page 232).
i The Logic7 ®
ON function enables
playback of stereo recordings, for instance,
with a surround sound experience for every
passenger. It enables optimum playback of
music and films on CDs, audio DVDs or
video DVDs with multichannel audio
formats, such as MLP™, dts™ or Dolby ®
Digital. This results in sound
characteristics like those intended by the
sound engineer when the original was
recorded.
i If you select Logic7®
OFF , the sound
system plays all playable formats as stored
on the medium. Due to the design of the
passenger compartment, an optimum
audio experience cannot be guaranteed for
all passengers.

Information about new versions of map
software can be obtained from an authorized
Mercedes-Benz Center.
You can have your map software updated
there with a DVD, or you can update it
yourself.
Updating processGWARNING
Never leave the engine running in enclosed
spaces. The exhaust gases contain toxic
carbon monoxide. Breathing in exhaust fumes
is a health hazard and can lead to
unconsciousness or death.
The update process can take a long time (over
an hour), depending on the size of the digital
map. During this time, you will only be able to
switch on radio mode and to accept incoming
calls. The update will be completed more
quickly if the vehicle is stationary.
If the starter battery is not sufficiently
charged, COMAND may end the process
automatically. This protects the battery. If
this occurs, restart the update with the
engine running.

center outwards rather than in a circular
motion.
R Place DVDs back in their cases after use.
R Protect DVDs from heat and direct sunlight.
Map software copy protection
Map software for COMAND is subject to a
charge. The map software has just one
activation code which is usable in one vehicle
only, and is not transferable. You can obtain
the six-digit activation code from an
authorized Mercedes-Benz Center. If you
have lost the activation code, contact an
authorized Mercedes-Benz Center. If
COMAND does not accept the activation
code that you have received, also contact an
authorized Mercedes-Benz Center.
Your vehicle is supplied with map software at
the factory. Depending on the country, map
software for your region is either pre-installed
or the map software is supplied as a DVD. You
do not require an activation code for the map
software that is provided with your vehicle.
If the map software on your vehicle has been
installed at the factory and you wish to
reinstall it, this also does not necessitate
entry of the activation code.
Installation processXLoad the map software DVD in the DVD
drive ( Y page 225).
COMAND checks the DVD and shows a
corresponding message in the display.
Map software is not compatible with the
navigation system
You will see a message that the map software

interior temperature for the vehicle. Cooling
also dehumidifies the air inside the vehicle
and, thereby, prevents the windows from
fogging up.

dehumidification, the vehicle will not be
cooled and the air not dehumidified in warm
weather conditions. The windows can mist up
faster. This could result in your no longer
