Safety precautions
Warning!G
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, for example:

Traffic lights

Stop and right-of-way signs

Parking or stopping prohibited areas

Lane merging

Other road and traffic rules and regula-
tions

Narrow bridges
COMAND may give incorrect navigation
commands if the data in the digital map
does not correspond with the actual
road/traffic situation. DVD maps do not
cover all areas nor all routes within an area.
For example, 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.Warning!G
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.

Map software
The digital maps generated by the map
software become outdated in the same
way as conventional road maps. Optimum
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 ver-
sions can be obtained from an authorized
Mercedes-Benz Center.Updating the map software
You can update the map software yourself
using a DVD.
Notes about handling DVDs

Only hold discs by the edge.

Handle discs carefully to prevent read
problems.

Avoid getting scratches, fingerprints
and dust on discs.

Use a commercially-available cleaning
cloth to clean discs. Do not wipe them
with a circular motion, but only in
straight lines from the center out-
wards.

Place discs back in their boxes after
use.

Protect discs from heat and direct sun-
light.
Updating process
The updating process has the following
phases:

Loading a DVD into the DVD changer
(
page 150)

Updating process (page 151)
iThe updating process can take between 10
and 60 minutes, depending on the size of the
map software. If the radio was switched on be-
fore you started the updating process, you can
still adjust the volume. You can also use
COMAND to operate the automatic air condition-
ing and to cancel the process. Other functions
are not operational.
If possible, carry out the update when the vehicle
is stationary.

Slide DVD into slot 1 with printed side
facing upwards.
COMAND loads the DVD.
iIf you carry out the update with the engine
switched off and the vehicle battery has insuffi-
cient power, COMAND may automatically switch
off during the process in order to protect the bat-
tery. If this occurs, restart the update with the
engine running period. Similarly, if the SmartKey
position is unintentionally switched to 0, restart
the update.
Warning!G
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.
iEach magazine tray button 2 indicates the
status of the corresponding magazine tray by
means of an LED.

LED off = magazine tray is empty

LED constantly lit = magazine tray is loaded

LED flashes = CD/DVD changer requesting

General notes
Operational readiness of the navigation
system following a system software
update by an authorized
Mercedes-Benz Center
After a system software update by an au-
thorized Mercedes-Benz Center, the in-
stalled map software may no longer be
compatible. If this is the case, the naviga-
tion system will not be operational.
You will know if this is the case, when the
following message will appear when you
switch to navigation mode: “The system
software has been updated. The map soft-
ware must be updated now. Please insert
the DVD with the map software.”
Updating map software: Proceed as
described in the “Updating the map
software” section (
page 149). Use
map software which is compatible with
the system software.Initial use or use following a system
software update
In both these cases, the navigation system
must determine the position of the vehicle.
You may have to drive for a while before
precise route guidance is possible.
GPS reception
Correct functioning of the navigation sys-
tem depends on GPS reception, among
other things. In certain situations, GPS re-
ception may be impaired, there may be in-
terference or no reception at all, e.g. in
tunnels, in multistory parking garages or
there is snow covering the trunk lid where
the GPS antenna is located. If there is
snow on the trunk lid it should be removed.Route guidance after vehicle transpor-
tation
COMAND has to redetermine the position
of the vehicle if the vehicle has been trans-
ported (e.g. by ferry, by train or after tow-
ing).
Positioning takes place automatically even
when COMAND is switched off. The dura-
tion varies from one case to another.
Route guidance may be restricted as fol-
lows during vehicle positioning:

Navigation announcements, route
guidance displays and displayed street
names are not consistent with the ac-
tual location of the vehicle.

COMAND does not generate navigation
announcements.

Instead of the route guidance displays,
you see the “Off Road” display and a di-
rection arrow. The direction arrow
shows the compass heading to the des-
tination.
iPlease note that the update must be allowed
to run to the end in this case. If you interrupt it,
the navigation system will continue to be non-op-
erational.

COMAND navigation (introduction)
When positioning is complete, route guid-
ance is once again possible using naviga-
tion announcements and route guidance
displays.
Interrupting the journey during route
guidance
The following applies if you interrupt the
journey during route guidance and contin-
ue the journey later:

COMAND resumes route guidance au-
tomatically if you continue the journey
within 2 hours.

Route guidance is canceled if you con-
tinue the journey after more than
2 hours. It will be necessary to resume
the canceled route guidance manually
(
page 203).Hard disk errors
COMAND has an integrated hard disk on
which the map software is saved.
If an area of the hard disk has an error,
COMAND can no longer access the map
data in this area, for example, when calcu-
lating a route.
The message “Navigation Unavailable.
Please refer to the operating instructions.”
appears.
Deleting message: Switch COMAND
off and back on.
Units of measurement
The units of measurement in navigation
mode are identical to those set in the in-
strument cluster.
Input restrictions
The input restrictions are imposed starting
at a particular vehicle speed. The restric-
tions are canceled as soon as the speed
drops below a certain value.
When the restriction is active, certain oper-
ations or entries are not possible.
You will notice this by the fact that some
menu items cannot be selected or certain
operations will not be possible.
iThe journey is interrupted if you park the ve-
hicle and switch off COMAND.
The journey is continued when you switch
COMAND back on and start driving on.
iIf you switch the navigation system off/on,
it will be operational again until it has to access
the faulty area of the hard disk again. The mes-
sage will then appear again. Consult an autho-
rized Mercedes-Benz Center.
