G
Any alteration of electronic components or
software can cause malfunctions.
Radio, satellite radio, amplifier, CD/DVD
changer, navigation module, telephone and
Voice Control systems* are interconnected.
Therefore, if one of the components is not
operational, or has not been removed/ re-
placed properly, the function of other com-
ponents 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.
Warning!
G
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 mph
(approximately 50 km/ h), your car covers a
distance of 44 feet (approximately 14 m) ev-
ery 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.
Warning!
G
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.
