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 whenoperating mobile communications equipment in
the vehicle.
If it is permitted by law to operate communica-
tions equipment while the vehicle is in motion,
you may do so only if the traffic situation per-
mits. You may otherwise be distracted 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 vehicle
electronics and mobile phones is minimised
An exterior aerial has the following advantages:
R it conducts the electromagnetic fields gener-
ated 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 358).
General notes Depending on the vehicle equipment, there are
various mobile phone brackets that may be fit-
ted in your vehicle; in some cases, these are
country-specific.
More information on suitable mobile phones,
mobile phone brackets and on connecting Blue-
tooth ®
-capable mobile phones with the multi-
media system can be obtained:
R at a qualified specialist workshop
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 298).
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 installation instruc-
tions for the mobile phone fitting.
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 tele-
phone module into the pre-installed fitting. This connects it to the exterior aerial. If you wish to
charge the mobile phone, 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.
Operating the mobile phone You can operate the phone using the
6and
~ buttons on the multifunction steering
wheel. You can operate other mobile phone
functions via the on-board computer
(Y page 230).
When you remove the key from the ignition lock, the mobile phone is disconnected from the vehi-cle. 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 transferred
over to the mobile phone. It is then possible to
continue the conversation on the mobile phone. 306

313Maintenance and care Z

Special service requirements
The prescribed service interval is based on nor-
mal operation of the vehicle. Service work will
need to be performed more often if the vehicle is
operated under arduous conditions or increased loads, for example:
R Regular city driving with frequent intermedi-
ate stops
R If the vehicle is primarily used to travel short
distances
R For frequent use in mountainous terrain or on
poor road surfaces
R If the engine is often left idling for long periods
In these or similar operating conditions, have
the air filter, engine oil and oil filter, for example, changed more frequently. The tyres must be
checked more frequently if the vehicle is oper-
ated under increased loads. Further informationcan be obtained at a qualified specialist work-
shop, e.g. a Mercedes-Benz Service Centre.
Driving abroad An extensive Mercedes-Benz Service network is
also available in other countries. You can obtain further information from any Mercedes-Benz
Service Centre. Care
General notes
! For cleaning your vehicle, do not use any of
the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective films
with hard objects, e.g. a ring or ice scraper.
You could otherwise scratch or damage the
surfaces and protective film.
! Do not park up your vehicle for a long period
of time immediately after cleaning, particu-
larly after cleaning the wheel rim with wheel
cleaner. Wheel cleaner may lead to increased corrosion of the brake discs and pads. You
should therefore drive for a few minutes after
cleaning. By heating up the brakes, the brake discs and pads dry. The vehicle can then be
parked up for a long period of time. H
Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man-
ner.
Regular care of your vehicle is a condition for
retaining quality in the long term.
Use care products and cleaning agents recom-
mended and approved by Mercedes-Benz. Washing the vehicle and cleaning the

Automatic car wash G
WARNING
Braking efficiency is reduced after the vehicle has been washed. There is a risk of an acci-
dent.
After washing the vehicle, brake carefully
while paying attention to the traffic conditions in order to restore full braking efficiency.
! When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicle brakes automat- ically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations:
R when towing away
R in a car wash
! Preferably use car washes with adjustable
high-pressure jets for pre-washing. This cor-
responds with the specifications for cabriolet programmes. In car washes that use high
water pressures, there is a risk that a small
amount of water may leak into the vehicle.
! Make sure that the vehicle is not subse-
quently treated with hot wax.
! Always remove the key before washing the
vehicle in a car wash. Doing so ensures that
the wind deflector on the windscreen
retracts. The wind deflector may otherwise be damaged.
! Make sure: 314
