WARNING
Making alterations to electronic components
can cause malfunctions.
Radio, satellite radio, amplifier, DVD changer,
navigation module, phone and voice control
are networked. If one component is not
functional or if it has been incorrectly
removed/replaced, this could impair the
operatio nofothercomponents.
This could seriously jeopardize the
operational safety of your vehicle.
We recommend that you always have
maintenance work on electronic components
carried out at an authorized Mercedes-Benz
Center. G
WARNING
In order to avoid distraction which could lead
to an accident, the driver should only enter
system settings with the vehicle at a standstill
and operate the system only when road,
weather and traffic conditions permit.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 feet (approximately 14 m) per
second. COMAND delivers information to simplify
your choice of route and guide you
comfortably and safely to your destination.
For safety reasons, we recommend that you
bring your vehicle to a standstill, paying
attention to road and traffic conditions,
before making or acceptin
gatelephone call
or viewing navigation maps ,instructions or
downloaded informatio nonthe COMAND
screen. G
WARNING
While the navigation system provides
directional assistance, the driver must remain
focused on safe driving behavior, especially
attention to traffic and street signs, and
should utilize the system's audio cues while
driving.
The navigation system does not supply any
information on stop signs, yield signs, traffic
regulations or traffic safety rules. Their
observance always remains in the driver's
personal responsibility. DVD maps do not
cover all areas nor all routes within an area. G
WARNING
This equipment complies with FCC radiation
exposure limits set forth for uncontrolled
equipment and meets the FCC radio
frequency (RF) Exposure Guidelines in
Supplement C to OET65.
This equipment has very low levels of RF
energy that is deemed to comply without
maximum permissive exposure evaluation
(MPE). But it is desirable that it should be
installed and operated with at least 8inches
(20 cm) and more between the radiator and a
person's body (excluding extremities: hands,
wrists, fee tand legs.) 282

i Work improperly carried out on electronic
components or systems (e.g. radio, DVD
changer) and associated software could
cause them to cease functioning. Even
systems that have not been modified could
be affected because the electronic
systems are connected. Electronic malfunctions can seriously jeopardize the
operational safety of your vehicle.
i Roof antenna functionality (telephone,
satellite radio, GPS) can be affected by the
use of roof carrier systems.
Attaching metallized retrofit film to the
windshield may affect radio reception and
have a negative impact on all other
antennas (e.g. emergency antenna) in the
vehicle interior.
i Therefore, have all work on or
modifications to electronic components
carried out at a qualified specialist
workshop. This workshop should have the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use an
authorized Mercedes-Ben zCenter for this
purpose. In particular, work relevant to
safety or on safety-related systems must
be carried out at a qualified specialist
workshop.
i Protection against theft: this device is
equipped with technical provisions to
protect it against theft. Further information
on protection against thef tcan be obtained
