Useful information
i These operating instructions describe all
the standard and optional equipment of
your COMAND system, as available at the
time of going to print. Country-specific
differences are possible. Please note that
your COMAND system may not be
equipped with all the features described.
This also applies to safety-related systems
and functions.

Operating safety
Important safety notes
G
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
operation of other components.
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 accepting a telephone call
or viewing navigation maps, instructions or
downloaded information on the 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 8
inches
(20 cm)

and more between the radiator and a
person's body (excluding extremities: hands,
wrists, feet and legs.) 268

Declarations of conformity
Vehicle components which receive
and/or transmit radio waves i
USA only: The wireless devices of this
vehicle comply with Part 15 of the FCC
Rules.
Operation is subject to the following
two conditions:
1. These devices may not cause harmful
interference, and
2. These devices must accept any
interference received, including
interference that may cause undesired
operation.
Changes or modifications not expressly
approved by the party responsible for
compliance could void the user’s authority
to operate the equipment.
i Canada only: The wireless devices of this
vehicle comply with RSS-210 of Industry
Canada. Operation is subject to the
following two conditions:
1. These devices may not cause harmful
interference, and
2. These devices must accept any
interference received, including
interference that may cause undesired
operation. Correct use
Observe the

following information when using
COMAND:
R the safety notes in this manual
R traffic rules and regulations
R laws and safety standards pertaining to
motor vehicles
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 metalized 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-Benz Center 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 theft can be obtained
from an authorized Mercedes-Benz Center. Information on copyright
