i If Audio Aux mode was active last, you only
need to select “
Audio”.
Within the audio function
Select “Audio” K “Aux”.
The Audio Aux menu appears.
The medium in the external audio
source is heard, provided it is connect-
ed and switched to playback.

Balance and fader (
page 36)
Treble and bass (
page 36)
Surround sound (
page 38)
i The volume of external audio sources is ex-
tremely variable. It is possible that a device con-
nected as an external audio source will sound
quieter or louder in the vehicle or that the usual
maximum volume cannot be achieved. On cer-
tain devices the volume can be set separately. In
this case, start at a moderate volume and in-
crease it slowly. In this way, you can determine
whether the system is capable of playback with-
out distortion, even at high volume.

GWarning
Due to the different volumes of the external
audio sources, system messages (e.g. navi-
gation announcements) may be much loud-
er. You may need to disable these system
messages or adjust the volume of these
messages manually (

page 35).

74 Video
DVD video
If the vehicle is travelling faster than ap-
proximately 3 MPH, the picture will switch
off automatically in DVD video mode.
The following message will then appear in
the display: “In order not to distract you
from the traffic situation, the picture is fad-
ed out while the vehicle is in motion.”.
As soon as the speed falls below approxi-
mately 3 MPH, the picture switches back
on again.
i When playing copied discs, problems may
occur with the playback.
A wide variety of disc-writing software and writ-
ers are available. Due to this variety we cannot
guarantee that the system will be able to play
discs that you have written/copied yourself
! Do not attach stickers or labels of any kind
to discs. They may come loose and damage
COMAND. Labels may also cause the disc to
bend, which may result in reading errors and
problems with disc recognition.
! COMAND has been designed for discs meet-
ing the requirements of standard EN 60908.
Therefore, only discs with a maximum thickness
of 1.3 mm can be used.
If a thicker disc is inserted, e. g. one which stores
data on both sides, (DVD on one side, audio data
on the other side), this cannot be ejected and
COMAND will be damaged.
Do not use 8 cm diameter discs, not even with an
adapter.
Only use round, 12 cm diameter discs.

Only touch the discs at the edges.

Handle discs with care in order to pre-
vent malfunctions during playback.

Avoid scratching, leaving fingerprints
and dust on the discs.

Clean the discs occasionally with a
commercially available cleaning cloth.
Always wipe in a straight line from the
inside outwards, never in a circular mo-
tion.

The discs must only be labelled using
pens specially designed for this pur-
pose.

Safety Precautions
Safety Precautions
G Warning
Some jurisdictions prohibit the driver from
using a cellular telephone while driving.
Whether or not prohibited by law, for safety
reasons, the driver should not use the cellu-
lar telephone while the vehicle is in motion.
Stop the vehicle in a safe location before
placing or answering a call.
If you nonetheless choose to use the mobile
phone while driving, please use the hands-
free feature and be sure to pay attention to
the traffic situation at all times. Use the mo-
bile phone only when road, weather and traf-
fic conditions permit. Otherwise, you may
not be able to observe traffic conditions and
could endanger yourself and others.
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.
G Warning
You and others may damag e y o u r h e a l t h d u e
to excessive electromagnetic radiation. By

health risks of electromagnetic fields, which
are under discussion among the scientific
community, should be largely prevented.
G Warning
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or
personal injury.

112 Navigation
Introduction
The digital data for the map software will
become obsolete, just like conventional
road maps. Optimum route guidance by
the navigation system is only achieved
with up-to-date map software. Information
on new map software versions is available
from an authorized Mercedes-Benz Center.
You can have the map software updated
there by means of a DVD or perform the
update process yourself.
Notes on DVD discs

Only touch the discs at the edges.

Handle the discs with care in order to
prevent reading errors.

Avoid scratching, leaving fingerprints
and dust on the discs.

Use a commercially available cleaning
cloth to clean discs. Always wipe in a
straight line from the inside outwards,
never in a circular motion.

After use, put the discs back into the
box.

Protect the discs from heat and direct
sunlight.
Introduction
Safety instructions
G Warning
For safety reasons, only enter a destination
when the vehicle is stationary. When the ve-
hicle is in motion, a passenger should enter
the destination. Study manual and select
route before driving.
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.
COMAND calculates the route to the desti-
nation without taking account of the follow-
ing:

Traffic lights

Stop and right-of-way signs

Lane merging

Parking or stopping prohibited areas

Other road and traffic rules and regula-
tions

Narrow bridges
G Warning
COMAND may give incorrect navigation
commands if the data in the digital map
does not correspond with the actual road/
traffic situation. Digital maps do not cover
all areas nor all routes within an area. For ex-
ample, if the traffic routing has been
changed or the direction of a one-way road
has been reversed.
For this reason, you must always observe
applicable road and traffic rules and regula-
tions during your journey. Road and traffic
rules and regulations always have priority
over the navigation commands generated by
the system.
G Warning
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
consulting the map display for directions.
Consulting the symbols or map display for
directions may cause you to divert your at-
tention from driving and increase your risk
of an accident.
Updating the map software

113 Navigation
Introduction
Update sequence
The sequence includes the following stag-
es:

Loading DVD into the DVD changer

Update process
i The update process may take between 60
and 150 minutes, depending on the size of the
map software.
If possible, perform the update when the vehicle
is stationary. The DVD read speed is faster when
the vehicle is stationary than when the vehicle is
moving and the update therefore takes less time.
If you perform the update with the engine off and
the vehicle battery is no longer powerful enough,
COMAND may shut off automatically during the
process to protect the battery. In this case, re-
start the update with the engine running.
You can interrupt the update process and contin-
ue it at a later time. If you cancel the update pro-
cess, the navigation system is not ready for
operation.
Loading DVD into DVD changer
The DVD changer is a magazine with six
built-in compartments.
1Disc slot
2Load button
Press the Load button2.
A menu indicates which magazine com-
partments are currently loaded.
To select an empty magazine com-
partment: Rotate ymz or slide omp.
To start loading: Press n.
The message “Please Insert Disc ”
will then be displayed.
Insert the DVD into the slot1 with the
printed side upwards.
The DVD changer pulls in the DVD. The
message “Loading Disc ...” will be
displayed.
i If the magazine is full, you will first need to
eject a disc (
page 57).
G Warning
Never leave the engine running in an en-
closed space. The exhaust gases contain
carbon monoxide. Inhaling exhaust gases
constitutes a health hazard and could lead
to loss of consciousness or even death.

Route guidance
COMAND guides you to the destination by
means of driving recommendations in the
form of navigation announcements or
route guidance displays.
i The route guidance displays only appear if
the display has been switched to navigation
mode.
If for some reason you do not follow the
driving recommendations or leave the cal-
culated route, COMAND automatically cal-
culates a new route to the destination.
If the map data contains corresponding in-
formation during route guidance
COMAND tries to avoid roads with limited
passability, e. g. roads that are blocked for
through-traffic and are for residents only.
Time restrictions of roads (e.g. blocked on
Sundays and public holidays) are only tak-
en into account for route guidance if the
digital map contains corresponding infor-
mation during the blocked time periods.Driving maneuvers are given in three phas-
es:

Once you have reached your destination, a
checkered flag is displayed and route guid-
ance is ended automatically.Route guidance to an off-road destina-
tion
COMAND can also guide you to destina-
tions that are within the area covered by
the digital map, but are not themselves in-
cluded on the map.
Such destinations are off-road destina-
tions, which you can enter, for example, by
entering the destination via the map.
In this case, COMAND guides you on roads
known to the system for as long as possi-
ble using navigation announcements and
route guidance displays.1Off-road destination

Just before reaching the last known point
on the map, the message “You will enter an
area with unreliable map data in xx miles” is
announced.
When the vehicle is entering the area that
is not covered by the digital map, the
screen is split. On the right half of the
screen an arrow appears that points to the
off-road destination

G Warning
The COMAND navigation system may direct
you to off-road routes that your vehicle may
not be capable of traversing through without
damaging your tires, wheels or vehicle. It is
the driver’s sole responsibility to determine
the suitability of the route. Off-road routes
may be of varying conditions and their ap-
propriateness for use may be affected by
various factors such as time of day, time of
year and immediate weather conditions that
cannot be judged or taken into consider-
ation by the COMAND system.
