 Operating safety
WarningG
Any alterations made to electronic compo-
nents and the software can cause malfunc-
tions.
The radio, amplifier, CD changer*, satellite 
radio*, telephone* and navigation module 
are interconnected. When one of the com-
ponents 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.
WarningG
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, 
weather and 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 44 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. DVD maps do not cover all 
areas nor all routes within an area.
