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
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 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. 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

Introduction
Safety notes G
WARNING
For safety reasons, onl yenter a destination
when the vehicle is stationary .When the
vehicle is in motion, apassenger should enter
the destination .Study manual and select
route before driving.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 fee t(approximately
14 m) every second.
COMAND calculates the rout eto the
destination without taking account of the
following:
R Traffic lights
R Stop and right-of-way-signs
R Lane merging
R Parking or stopping prohibited areas
R Other road and traffic rules and regulations
R Narrow bridges G
WARNING
COMAND may give incorrect navigation
commands if the data in the digital map does
not correspond with the actual road/traffic
situation. Digital maps do not cover all areas
nor all routes within an area. For example, if
the traffic routing has been changed or the
direction of a one-way road has been
reversed.
For this reason, you must always observe
applicable road and traffic rules and
regulations during your journey. Road and
traffic rules and regulations always have
priority over the navigation commands
generated by the system. G
WARNING
Navigation announcements are intended to
direct you while driving without diverting your
attention from the road and driving. Please always use this feature instead of
consulting the map display for directions.
Looking at the icons or map display can
distract you from traffic conditions and
driving, and increase the risk of an accident.
General information Operational readiness of the navigation
system
The navigation system must determine the
position of the vehicle before first use or
whenever operational status is restored.
Therefore, you may have to drive for a while
before precise route guidance is possible.
GPS reception
Correct functioning of the navigation system
depends, amongst other things, on GPS
reception
.Incertain situations, GPS
reception may be impaired, there may be
interference or there may be no reception at
all, e.g. in tunnels or parking garages.
Entry restriction
On vehicles for certain countries, there is a
restriction on entering data.
The restriction is active from a vehicle speed
of over approximately 3 mph (5 km/h). As
soon as speed falls below approximately
2 mph (3 km/h), the restriction becomes
inactive.
When the restriction is active, certain entries
cannot be made. This will be indicated by the
fact that certain menu items are grayed out
and cannot be selected.
The following functions, for example, may
therefore not be available while the vehicle is
in motion:
R entering the destination city and street
R entering a destination via the map
R entering points of interest in the vicinity of
a city or via a name search
R editing entries
R using the number keypad for direct entry 138
