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

Cleaning the exhaust tail pipes G
WARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
! Do not clean the exhaust pipe with acid-
based cleaning agents such as sanitary
cleansers or wheel cleaners.
Impurities combined with the effects of road
grit and corrosive environmental factors may cause flash rust to form on the surface. You
can restore the original shine of the exhaust
pipe by cleaning it regularly, especially in win- ter and after washing. X
Clean the exhaust pipe with a care product
tested and approved by Mercedes-Benz.

instructions.
The ball coupling must be cleaned if it
becomes dirty or corroded. X Remove rust on the ball, e.g. with a wire
brush.
X Remove dirt with a clean, lint-free cloth or a
brush.
