the operation of any equipment, your au-
thorized Mercedes-Benz Center will be

res.
We continuously strive to improve our pro-
duct and ask for your understanding that
we reserve the right to make changes in design and equipment. Therefore, informa-
tion, illustrations and descriptions in this
manual might differ from the equipment in-
stalled in your vehicle. As such, the infor-
mation, illustrations and descriptions
contained in this manual may not be reaso-
nably relied upon in making any claims
with respect to the actual performance of
the product.
These operating instructions form an inte-
gral part of the vehicle and should there-
fore always be kept inside the vehicle and
passed on to the new owner if the vehicle
is sold.
We extend our best wishes for many miles
of safe, pleasurable driving.

Operating safety
Operating safety
Warning
G
Any alterations made to electronic compon-
ents and the software can cause malfunc-
tions.
The radio, amplifier, CD changer and tele-
phone* are interconnected. When one of the
components is not operational or has not
been removed/replaced properly, the func-
tion of other components may be impaired.
This condition might seriously impair the
operating safety of your vehicle.
We recommend that you have any service
work on electronic components carried out
by an authorized Mercedes-Benz Center.
Warning
G
In order to avoid distraction, which could
lead to an accident, system settings should
be entered with the vehicle at a standstill.
The driver should only operate the system
when traffic conditions permit.
Bear in mind that at a speed of just
30 mp/h (approximately 50 km/h), your car
is covering a distance of 50 feet (approxima-
tely 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 encoura-
ge the driver to stop the vehicle in a safe
place before answering or placing a call, or
consulting the COMAND screen to read na-
vigational maps, instructions, or downloa-
ded information.
While the navigation system provides direc-
tional assistance, the driver must remain fo-
cused on safe driving behavior, including
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. This al-
ways remains your personal responsibility
when you drive. CD maps do not cover all
areas nor all routes within an area.
