Rwhen the seat heating is in operation, do
not cover the seats with insulating
materials, e.g. blankets, coats, bags,
seat covers, child seats or booster seats.

Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
which was available at the time of
purchase. Country-specific differences are
possible. Bear in mind that your vehicle
may not feature all functions described
here. This also refers to safety-related
systems and functions.
Introduction
Operating safety
General notes
GRisk of accident and injury
Vehicles with HYBRID: ensure that you read
the "HYBRID" supplement. You may otherwise
fail to recognize dangers.
GWarning
Any alterations of electronic components or
software can cause malfunctions.
Radio, satellite radio, amplifier, DVD changer,
navigation module, telephone and Voice
Control systems are interconnected.
Therefore, if one of the components is not
operational, or has not been removed/
replaced properly, the function of other
components could be impaired.
Such conditions might seriously impair the
operating safety of your vehicle.
We recommend to have any service work on
electronic components carried out by an
authorized Mercedes-Benz Center.
GWarning
In order to avoid distraction which could lead
to an accident, the driver should enter system
settings while the vehicle is at a standstill, and
operate the system only when permitted by
road, weather and traffic conditions.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your car covers a
distance of 44 feet (approximately 14 m) every
second.
COMAND supplies you with information to
help you select your route more easily and
guide you conveniently and safely to your
destination. For safety reasons, we
encourage the driver to stop the vehicle in a
safe place before answering or placing a call,
or consulting the COMAND screen to read
navigational maps, instructions, or
downloaded information.GWarning
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.
This device complies with Part 15 of the FCC
Rules. Both of the following conditions must
be fulfilled to be approved for use:
(1) This device may not cause harmful
interference, and(2) This device must accept all external
interference, including interference that may
cause undesired operating problems.GWarning
Change or modification not expressly
approved by the party responsible for
compliance could void the user's authority to
operate this equipment.
! Note: This equipment has been tested
and found to comply with the limits for a
Class A digital device, pursuant to Part 15
of the FCC Rules. These limits are designed
to provide reasonable protection against
harmful interference when the equipment
114IntroductionCOMAND

is operated in a commercial environment.
This equipment generates, uses and can
radiate radio frequency energy and, if not
installed and used in accordance with the
instruction manual, may cause harmful
interference to radio communications.GWarning
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.)
Correct use
Observe the following information when using
COMAND:
R the safety notes in this manual
R all road traffic regulations
i Improper work on electronic components
or other systems (such as radio, DVD
changer) and their software may result in
malfunction or failure. 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 Only have work or changes to electronic
components carried out at a qualified
specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required. Daimler
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

therefore differ from some of the descriptions
or illustrations. The original purchase
agreement lists all systems installed in your
vehicle. Contact an authorized Mercedes-
Benz Center if you have any questions about
equipment or operation.
Function restrictions
