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
