Safety instructions
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 navi-
gation announcements guide you. Stop at a
safe location before using buttons or mak-
ing corrections.
Traffic regulations always have priority over
any route recommendations given.
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.
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
which can be serviced by the user. For safe-
ty reasons, have any service work which
may be necessary performed only by quali-
fied personnel.

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
designed for the SLK-Class (R171)
COMAND system. No other CDs or DVDs
will work. Using other navigation CDs or
DVDs might lead to malfunctions.
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.
The DVD is loaded into (and ejected from)
the navigation computer.
The navigation computer is mounted in the
center of the trunk.1Ejecting DVDs
2DVD slot
Loading
Insert the DVD into the DVD slot 2
face up.
The navigation computer pulls the DVD
in.
Tips on the navigation DVD
Loading/ejecting the DVD
i
Your Navigation DVD drive has been
designed to play DVDs which corre-
spond to the IEC 60908 standard.
If you insert thicker data carriers, e.g.
ones that have data on both sides (one
side with DVD data, the other side with
audio data), they cannot be ejected
and will damage the drive.
