Important safety notes G
WARNING
Operating mobile communications equip-
ment while driving distracts you from paying
attention
to traffic conditions. This could also
cause you to lose control of the vehicle. There
is a risk of an accident.
Use this device only when the vehicle is sta-
tionary.
i You must observe the legal requirements
for the country in which you are currently
driving when operating mobile communi-
cations equipment in the vehicle.
If it is permitted by law to operate commu-
nications equipment while the vehicle is in
motion, you may only do so if the traffic sit-
uation permits. You may otherwise be dis-
tracted from the traffic conditions, cause
an accident and injure yourself and others.
Excessive levels of electromagnetic radiation
may cause damage to your health and to the
health of others. The use of an exterior aerial
takes into consideration the scientific discus- Features

sion surrounding the possible health risk
posed by electromagnetic fields.
Mercedes-Benz recommends the use of an
approved exterior aerial. This ensures:
R
optimal mobile phone reception quality in
the vehicle
R mutual influences between the vehicle
electronics and mobile phones are mini-
mised
An exterior aerial has the following advan-
tages:
R it
conducts the electromagnetic fields gen-
erated by a wireless device to the exterior.
R the field strength in the vehicle interior is
lower than in a vehicle that does not have
an exterior aerial.
