Ris
kofa ccident
Observe the lega lrequirements of the country
in which you are currently driv ingr egarding
operating mobile communications equipment
in av ehicle.
If it is permitted by law to operate communi-
cations equipment while the vehic leis in
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 injur eyourself and others.
Two-way rad iosa nd fax equipment use dwith-
out low-reflection exter iora erials can inter-
fere with the vehicle's electronics and thereby
jeopardis ethe operating safety of the vehicle
and your safety. Therefore, you must only use
this equipment if it is correctly connected to
as eparate reflection-free exterior aerial. G
Risk of injury
Excessive levels of electromagnetic radiation
may cause damage to your health and the
health of others. Usin ganexterior aerial takes
into account current scientific discussions
relating to the possible health risk posed by
electromagnetic fields.
To ensure optimum reception quality for
mobil ephones in the vehicle and to minimise
mutua linfluences between the vehicl eelec-
tronics and mobile phones, Mercedes-Benz
recommends the use of an approved exterior
aerial. An exterior aerial conduct sthe elec-
tromagnetic fields generated by awireless
device to the exterior of the vehicle; the field
strength within the vehicle interior is lower
than in avehicle that does not have an exte-
rior aerial.
i There are various mobile phone brackets
that may be fit tedtoy our vehicle; in some
cases, these ar ecountry-specific. You can
obtain these mobile phone bracke ts from a
qualified specialist workshop, e.g. a
Mercedes-Benz Servic eCentre. The functions and services available when
you use the phone depend on your mobile
phone model and service provider.
Inserting the mobile phone
X Open the telephone compart ment
(Y page 245).
X Place the mobil ephone bracket int othe
pre-installed bracket ;see the separate
mobile phone bracket installation instruc-
tions.
X Insert the mobile phone into the mobile
phone bracket ;see the separate mobile
phone bracket installation instructions.
If the mobile phone is inser tedint he mobile
phone bracket ,you can speak to the person
you ar ecalling using the hands-free system.
You can operate the telephone using the
6 and~ button sonthe multifunc tion
steerin gwheel. You can operate other mobile
phone func tions via the on-boar dcomputer
(Y page 200).
When you tak ethe key out of the ignition lock,
the mobile phone stay sonb ut you can no
longer use the hands-free system.
If you are making acall and you would like to
take the key out of the ignition lock, first
remove the mobile phone from the bracket.
Otherwise, the call will be ended. Floormat on the driver'
sside G
Risk of accident
Make sure that there is sufficien tclearance
around the pedals when floormats are used,
and that the floormats are properly secured.
The floormats must be correctly secured at all
times using retainer sand press-s tuds.
Befor eyou driv eoff, check the floormat sand
secure if necessary. Afloormat which is not
properly secured can slip and, thereby, inter-
fere with the movemen tofthe pedals.
Do not plac efloormats on top of one another. 254
