Warning
G
Any alterations made to electronic compo-
nents and the software can cause malfunc-
tions.
The radio, amplifier, CD changer, navigation
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.

Important notesIn chapter “Telephone”, you will find de-
tailed information regarding the telepho-
ne*, including emergency call, SMS
function and service numbers.
1 Observe all legal requirements
Please read the chapter “Telephone”
first before attempting to operate your
telephone.
Always drive with extreme caution
when you operate the telephone
hands-free.
For safety reasons, you should not use
the mobile telephone handset to make
a call while driving the vehicle.
If the signal strength is very weak (dis-
play in the symbol field of all menus):
Wait until reception improves before
making a call.
Warning
G
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle. Whether or not prohibited by law, for
safety reasons, the driver should not use the
cellular telephone while the vehicle is in mo-
tion. Stop the vehicle in a safe location be-
fore answering or placing a call.
If you nonetheless choose to use the cellular
phone while driving, please use the hands-
free device and be sure to pay attention to
the traffic situation at all times. Use the cel-
lular phone
1 only when road, weather and
traffic conditions permit.
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e.
without being connected to an external an-
tenna) from inside the vehicle while the en-
gine is running. Doing so could lead to
malfunction of the vehicle’s electronic sys-
tems, possibly resulting in an accident and
personal injury.
!Radio transmitters, such as a portable
telephone or a citizens band unit
should only be used inside the vehicle
if they are connected to a separate ex-
terior antenna that has been approved
by Mercedes-Benz.
