Important safety notes G
DANGER
When a suitable device is connected, the
230 V power socket will be carrying a high
voltage. You could receive an electric shock if the connector cable or the 230 V power
socket is pulled out of the trim or is damaged
or wet. There is a risk of fatal injury. R
Use only connector cables that are dry and
free of damage.
R When the ignition is off, make sure that the
230 V power socket is dry.
R Immediately have the 230 V power socket
checked or replaced at a qualified special-
ised workshop if it is damaged or has been
pulled out of the trim.
R Never plug the connector cable into a 230 V
power socket that is damaged or has been
pulled out of the trim. G
DANGER
If you reach into the power socket or plug
inappropriate devices into the power socket,
you could receive an electric shock. There is a risk of fatal injury.
Only attach appropriate objects to the powersocket.
! Note that work and repairs on the 230 V
power socket should only be carried out by qualified specialist personnel.
General notes The 230 V power socket provides an alter-
nating voltage of 230 V so that small elec-
tronic devices can be connected. These devi-
ces, such as games consoles, chargers and
laptops, must not consume more than a max- imum of 150 watts altogether.
Do not connect any multiple socket outlets to the 230 V power socket.
Requirements for operating these devices:
R the electronic device that you connect has
a suitable connector and conforms to
standards specific to the country you are in.
R the electronic device connector is plugged
into the 230 V power socket.
R the maximum wattage of the device to be
connected must not exceed 150 watts.
R the on-board voltage is within a permissible
voltage range.

Mobile phone
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.
You must observe the legal requirements for
the country in which you are currently driving when operating mobile communications
equipment in the vehicle.
If it is permitted by law to operate communi-
cations 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- 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 that mutual interference between the vehi-
cle electronics and mobile phones is 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
Information on retrofitting two-way radios
and mobile phones (RF transmitters)
(Y page 466). General notes Depending on the vehicle equipment, there
are various mobile phone brackets that may
be fitted in your vehicle; in some cases, these
are country-specific.
More information on suitable mobile phones,
mobile phone brackets and on connecting
Bluetooth ®
-capable mobile phones to
COMAND Online/Audio 20 can be obtained:
R at your Mercedes-Benz Service Centre
R on the Internet at http://www.mercedes-
benz.com/connect
The functions and services available when
you use the phone depend on your mobile
phone model and service provider.
Using a mobile phone To connect a mobile phone to the exterior
aerial and charge it, insert it into the mobile
phone bracket.
X Open the telephone compartment
(Y page 370).
X Place the mobile phone bracket into the
pre-installed fitting; see the separate instal- lation instructions for the mobile phone fit-
ting.
X Insert the mobile phone into the mobile
phone bracket; see the separate installa-
tion instructions for the mobile phone fit-
ting.
i The mobile phone can also be operated
without being in the bracket. However, the charging function and aerial function are
not available.
In order to use Bluetooth ®
(SAP profile) on
your telephone module, you must first insert
the telephone module into the pre-installed
fitting. This connects it to the exterior aerial.
If you wish to charge the mobile phone, then
you must connect it to a USB port.
Further information on the telephone module
with Bluetooth ®
(SAP profile) can be found in
the Digital Owner's Manual. 386
FeaturesStowing and features

Operating the mobile phone
You can operate the telephone using the
6
and~ buttons on the multifunction
steering wheel. You can operate other mobile
phone functions via the on-board computer
(Y page 304).
When you remove the key from the ignition
lock, the mobile phone is disconnected from
the vehicle. You can then no longer make calls using the hands-free system.
If a call is active and you remove the key from
the ignition lock, the conversation is trans-
ferred over to the mobile telephone. It is then possible to continue the conversation on the
mobile phone. Floormats
G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor- mats on top of one another. X
Slide the relevant seat back.
X To fit: lay the floormat in the footwell. X
Press studs :onto retainers ;.
X To remove: pull the floormat away from
retainers ;.
X Remove the floormats. Retrofitted anti-glare film
Retrofitted anti-glare film on the inside of the
windows can interfere with radio/mobile
telephone reception. This is particularly the
case for conductive or metallic-coated films.
You can obtain information about anti-glare
film from a qualified specialist workshop. Features
