3 Introduction
Operating safety

Operating safety
Warning
G
Any alterations made to electronic compo-
nents and the software can cause malfunc-
tions.
The radio, amplifier, CD changer*, navigati-
on module, satellite radio*, telephone* and
voice control system* are interconnected.
Therefore, when one of the components is
not operational or has not been removed/
replaced properly, the function 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
only by qualified personnel.
Warning
G
In order to avoid distraction which could
lead to an accident, the driver should enter
system settings with the vehicle at a stand-
still and operate the system only when road
and traffic conditions permit.
Bear in mind that at a speed of just
30 mph (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.
