fere with the vehicle's electronics and thereby
jeopardise the operating safety of the vehicle
and your safety. Therefore, you must only use
this equipment if it is correctly connected to
a separate reflection-free exterior aerial. 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.
i There are various mobile phone brackets
that may be fitted in your vehicle; in some
cases, these are country-specific.
i You can connect a Bluetooth ®
-capable
mobile phone with Audio 20 or COMAND
Online via the Bluetooth ®
interface. This
also applies if your vehicle is equipped with
convenience telephony.
More information on suitable mobile phones,
mobile phone brackets and on connecting
Bluetooth ®
-capable mobile phones with
Audio 20 or COMAND Online can be obtained:
R at your Mercedes-Benz Service Centre
R on the Internet at http://www.mercedes-
benz.com/connect i
The functions and services available when
you use the phone depend on your mobile
phone model and service provider.
Using a mobile phone If the mobile phone is inserted in the mobile
phone bracket, you can speak to the person
you are calling using the hands-free system.
X
Open the telephone compartment
(Y page 297).
X Place the mobile phone bracket into the
pre-installed fitting (see the separate
installation instructions for the mobile
phone fitting).
X Insert the mobile phone into the mobile
phone bracket (see the separate installa-
tion instructions for the mobile phone fit-
ting).
i On some mobile phone brackets, you first
have to connect the mobile phone via Blue-
tooth ®
to the mobile phone bracket (see
the separate operating instructions for the
mobile phone bracket).
If this is the case, the mobile phone does
not have to be inserted into the bracket for
you to be able to use the telephone func-
tions. However, the charging function and
aerial function are not available.
Operating the mobile phone You can operate the telephone using the
6
and~ buttons on the luxury multi-
function steering wheel. You can operate
other mobile phone functions via the on-
board computer (Y page 234).
When you remove the key from the ignition
lock, the mobile phone stays switched on.
However, you can no longer use the hands-
free system.
If you have an active call and would like to
take the key out of the ignition lock, first
remove the mobile phone from the bracket. Features
