WarningG
For safety reasons, you should only enter a
destination when the vehicle is stationary.
When the vehicle is in motion, a passenger
should enter the destination. Study manual
and select route before driving.
Do not watch display screen or operate but-
tons while the vehicle is in motion - let voice
instructions guide you. Stop at a safe loca-
tion before using buttons or making correc-
tions.
Traffic regulations always have priority over
any route recommendations given.
Bear in mind that at a speed of just
30 m.p.h. (approximately 50 km/h), your
car is covering a distance of 44 feet (approx-
imately 14 m) every second.
The route calculated by COMAND is a rec-
ommendation on how to best reach your se-
lected destination.
During route guidance, you will not receive
any information on
Traffic lights
Stop and yield signs
Parking or stopping zones
One-way streets
Narrow bridges
Similar traffic regulation data
You should therefore always strictly observe
traffic regulations while driving. Drive care-
fully and always obey traffic laws and road
signs even if they contradict COMAND in-
structions.
WarningG
The Navigation DVD module contains a
Class 1 laser product. There is a danger of
invisible laser radiation if the cover is
opened or damaged.
Do not remove the cover. The Navigation
DVD module does not contain any parts ser-
viceable by the user. For safety reasons,
have any necessary service work performed
by qualified personnel.
The display unit can cause injury if contac-
ted when open. Return the display unit after
inserting a Navigation DVD to its closed po-
sition (
page 204).

Important notes
COMAND calculates the route with the
help of data that is stored on the naviga-
tion DVD.
Only use Mercedes-Benz navigation DVDs.
Using other navigation DVDs or CDs will
cause malfunctions and/or damage.
Because of changes in local traffic patterns
(e.g. road works) and/or incomplete data,
errors in calculation may occur.
As a result, the recommended route may
deviate from the ideal route. The data
stored on the DVD only reflects local con-
ditions at the time of DVD production. DVD
maps do not cover all areas nor all routes
within an area. Loading/ejecting a DVD
DVDs are loaded and ejected at the DVD
Navigation slot. The DVD Navigation slot is
located behind the display unit.
Open the display unit to get access to
the DVD Navigation slot as described in
“Starting an update” (
page 205).
Navigation DVD!
GPS (Global Positioning System) sig-
nals received make it possible to deter-
mine the current vehicle position.
Deviations from the actual position
may occur
if the reception of GPS signals is
disturbed e.g. in parking garages
and tunnels
if road conditions are bad
depending on the vehicle’s condi-
tion
i
There are two l buttons. One is on
the display unit. The other is located
left of the DVD NAVIGATION slot
behind the display (

Important notes
If your vehicle has been transported (e.g.
by a car, train or ferry) the system may
make navigation announcements which do
not correspond to the vehicle’s position.
The system needs to redetermine its
position.
Determining the location after the
vehicle has been transported
The system will need some time to
determine its location after the car has
been transported. The time required for
the system to do so varies from case to
case.
Switch the COMAND on.
Activate the Navigation main menu
(
page 146).
The navigation DVD needs to be in the
DVD NAVIGATION slot (
page 204).
Drive and press c.
Drive until the position or the road
indicated correspond to the real
circumstances. The system is now
correctly adjusted.
