Operating safety
This device complies with Part 15 of the

(2) This device must accept any interfer-
ence received, including interference
that may cause undesired operation.
Operating safety
G Warning
Any alterations of electronic components or
software can cause malfunctions.
Radio, satellite radio, amplifier, DVD chang-
er, navigation module, telephone and Voice
Control systems are interconnected. There-
fore, if one of the components is not opera-
tional, 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 au-
thorized 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 mp/h (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 encour-
age the driver to stop the vehicle in a safe
place before answering or placing a call, or
consulting the COMAND screen to read nav-
igational maps, instructions, or downloaded
information.
G Warning
While the navigation system provides direc-
tional assistance, the driver must remain fo-
cused 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 ob-
servance always remains in the driver’s per-
sonal responsibility. DVD maps do not cover
all areas nor all routes within an area.

10 Introduction
Operating safety
! NOTE: This equipment has been tested and
found to comply with the limits for a Class A dig-
ital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable
protection against harmful interference when
the equipment is operated in a commercial envi-
ronment. This equipment generates, uses and
can radiate radio frequency energy and, if not in-
stalled and used in accordance with the instruc-
tion manual, may cause harmful interference to
radio communications.G Warning
Change or modification not expressly ap-
proved by the party responsible for compli-
ance could void the user's authority to
operate this equipment.
G Warning
This transmitter must not be co-located or
operated in conjunction with any other an-
tenna or tranmitter.
G Warning
This equipment complies with FCC radiation
exposure limits set forth for uncontrolled
equipment and meets the FCC radio fre-
quency (RF) Exposure Guidelines in Supple-
ment C to OET65.
This equipment has very low levels of RF en-
ergy that is deemed to comply without max-
imum permissive exposure evaluation
(MPE). But it is desirable that it should be in-
stalled and operated with at least 8 inches
(20 cm) and more between the radiator and
person's body (excluding extremities:
hands, wrists feet and legs.)

11 Introduction
Operating safety
DaimlerChrysler declares herewith that
this device conforms to the basic
requirements and the other relevant
regulations of Directive 1999/5/EC (RTTE
Directive).
Please bear the following information in
mind when using the COMAND:

The safety instructions in this guide

Road Traffic Regulations
i Tampering with electronic components or
systems (e.g. radio, DVD changer) and their soft-
ware may result in malfunctioning. Systems
which have not been changed may be affected
due to the connectivity of the electronics.
Malfunctions of the electronics can seriously en-
danger the operational safety of your vehicle.
i Always have all work or modifications to
electronic components carried out by a qualified
specialist workshop with the necessary exper-
tise and tools for any work required.
DaimlerChrysler recommends a Mercedes-Benz
Service centre for this purpose.
Especially for safety-related operations and op-
erations on safety-related systems, servicing by
a qualified specialist workshop is essential.
For safety reasons, some COMAND func-
tions are restricted or not available when
the vehicle is moving. This can be recog-
nized, for example, from the fact that cer-
tain menu items cannot be selected or the
COMAND displays a corresponding mes-
sage.

G Warning
Some jurisdictions prohibit the driver from
using a cellular telephone while driving.
Whether or not prohibited by law, for safety
reasons, the driver should not use the cellu-
lar telephone while the vehicle is in motion.
Stop the vehicle in a safe location before
placing or answering a call.
If you nonetheless choose to use the mobile
phone while driving, please use the hands-
free feature and be sure to pay attention to
the traffic situation at all times. Use the mo-
bile phone only when road, weather and traf-
fic conditions permit. Otherwise, you may
not be able to observe traffic conditions and
could endanger yourself and others.
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.
G Warning
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or
personal injury.
