GWarning
When opening or closing the sliding sunroof,
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.
The sliding sunroof operates differently when
the sliding sunroof switch is pressed and held.
See the "Problems with the sliding sunroof"
section for more details.
The opening/closing procedure of the sliding
sunroof can be immediately halted by
releasing the sliding sunroof switch or, if the
sliding sunroof switch was moved past the
resistance point and released, by moving the
sliding sunroof switch in any direction.
GWarning
The sliding sunroof is made out of glass. In the
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.
! Only open the sliding sunroof if it is free
of snow and ice. Otherwise, malfunctions
may occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could
be damaged.
! If the sliding sunroof cannot be opened or
closed due to a malfunction, contact a
qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center.
! Do not forget that the weather can
change abruptly. Make certain that the
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
to the usual airflow noises when the sliding
sunroof is open. They are caused by minor
pressure fluctuations in the vehicle interior.
Change the position of the sliding sunroof
or open a side window slightly to reduce or
eliminate these noises.
Operating the sliding sunroof
Opening and closing
i You can continue to operate the sliding
sunroof after switching off the engine or

Surround sound
General notes
If your vehicle is equipped with the harman/
kardon® Logic 7® surround sound system,
you can set the optimum surround sound for
every passenger.
The harman/kardon® Logic 7® surround
sound system is available for the following
operating modes:
Rradio (FM only)
Rsatellite radio
Raudio CD
Raudio DVD (MLP, dts, PCM and Dolby
Digital audio formats)
RMP3 (including SD memory card)
RBluetooth® audio mode
RMedia Interface
Rvideo DVD (PCM, dts and Dolby Digital
audio formats)
RAUX
Because many DVDs contain both stereo and
multi-channel audio formats, it may be
necessary to set the audio format
(Y page 210).
iThe Logic7® On function enables
playback of, e.g. stereo recordings with a
surround sound experience for every
passenger. It enables optimum playback of
music and films on CD, audio DVD or video
DVD with multichannel audio formats, such
as MLP, dts or Dolby Digital. The resulting
audio experience reflects that intended by
the sound engineer during the original
recording.
iIf you select LOGIC7® Off, the sound
system plays the tracks as stored on the
medium. Due to the design of the
passenger compartment, an optimum
audio experience cannot be guaranteed for
all passengers.
iDiscs which support the audio formats
mentioned have the following logos:
Dolby Digital
dts
MLP

GWarning
Navigation announcements are intended to
direct you while driving without diverting your
attention from the road and driving.
Please always use this feature instead of

Installing new map software
The digital data generated by the map
software becomes outdated in the same way
as conventional road maps. Optimal route
guidance can only be provided by the
navigation system in conjunction with the
most up-to-date map software. Information
about new map software versions can be
obtained from an authorized Mercedes-Benz
Center.
You can install new map software yourself
using one or more DVDs, depending on the
size.
The installation process can take between 10
and 120 minutes depending on the size of the
map software. If radio mode is selected
before you start the installation process, you
can still adjust the volume. It is also still
possible to operate the automatic climate
control and cancel the process on COMAND.
Other functions are not operational. If
possible, carry out the installation process
when the vehicle is stationary. This takes less
time, since the DVD read speed is higher
when the vehicle is stationary than when it is
in motion. If the starter battery is not
sufficiently charged, COMAND may end the
process automatically in order to preserve
the battery. Therefore, keep the engine
running during the installation process.
GWarning
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.

Notes on handling DVDs
R Only touch the edges of DVDs.
R Handle DVDs carefully to avoid read errors.
R Avoid scratching DVDs or getting
fingerprints or dust on them.
R Use a conventional cleaning cloth to clean
DVDs. Never wipe in a circle, but instead in
straight lines from the inside to the outside.
R Place DVDs back in their cases after use.
R Do not expose DVDs to heat or direct
sunlight.
Map software copy protection
Map software for COMAND is subject to a fee.
Map software can only be used on one vehicle
with an activation code and is not
transferable. The six-digit activation code is
available at your authorized Mercedes-Benz
Center. Contact your authorized Mercedes-
Benz Center if you lose the activation code or
if COMAND does not accept the code that you
received.
Your vehicle is delivered from the factory with
map software. Depending on the country,
map software for your region is either pre-
installed (Europe/USA) or the map software

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
being able to observe the traffic conditions
properly and you may cause an accident.

Changing bulbs
Important safety notes
Xenon bulbs
If your vehicle is equipped with Xenon bulbs,
you can recognize this by the following: the
cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before starting the engine.
GWarning
Xenon bulbs carry a high voltage. You could
get an electric shock and be seriously or even
fatally injured if you touch the electric
contacts on Xenon bulbs. Therefore, never
remove the cover from Xenon bulbs.
Do not change Xenon bulbs yourself, but have
them replaced at a qualified specialist
workshop which has the necessary specialist
knowledge and tools to carry out the work
required.
Mercedes-Benz recommends that you use an
authorized Mercedes-Benz Center for this
purpose. In particular, work relevant to safety
or on safety-related systems must be carried
out at a qualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.
Other bulbsGWarning!
Bulbs and lamps can be very hot. You should
therefore allow them to cool down before you
change them. Otherwise, you could be burned
if you touch them.
Keep bulbs out of the reach of children.
Otherwise, they could damage the bulbs, for
example, and injure themselves.
Never use a bulb which has been dropped.
Such a bulb may break or even explode and
injure you.
Halogen bulbs are pressurized and can
explode when you change them, particularly
if they are very hot. You should therefore wear
eye protection and gloves when you are
changing them.
There are bulbs other than the Xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y page 251). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
Mercedes-Benz recommends that you use an
authorized Mercedes-Benz Center for this
purpose. In particular, work relevant to safety
or on safety-related systems must be carried
out at a qualified specialist workshop.
If you require assistance changing bulbs,
consult a qualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the service life of the bulbs. Always use a lint-
free cloth or only touch the base of the bulb
when installing.
Only use bulbs of the correct type.
