motion, you must only do so if the traffic sit-
uation permits. Otherwise, you could be dis-
tracted from the traffic conditions, cause an
accident and injure yourself and others.
Two-way radios and fax equipment used with-
out low-reflection exterior aerials can inter-
fere with the vehicle's electronics and thereby
jeopardise the operating safety of the vehicle
and yours afety. Therefore, you must only use
this equipment if it is correctly connected to
a separate reflection-free exterio raerial. G
WARNING
Excessive levels of electromagnetic radiation
may cause damage to your health and the
health of others. Using an exterior aerial takes
into account current scientific discussions
relating to 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.
