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 478). 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 392).
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. 410

Important safety notes G
WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refuelling. G
WARNING
Fuels are poisonous and hazardous to health. There is a danger of injury.
Do not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel
vapours. Keep fuels out of the reach of chil-
dren.
If you or others come into contact with fuel,
observe the following:
R Wash the fuel off any affected areas of skin
with water and soap immediately.
R If you get fuel in your eyes, rinse them thor-
oughly with clean water immediately. Seek immediate medical attention.
R If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contact with fuel immediately. Service products and capacities

Fuel consumption information H
Environmental note
CO 2(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO 2emissions are directly related to
fuel consumption and therefore depend on:
R efficient use of the fuel by the engine
R driving style
R other non-technical factors, such as envi-
ronmental influences, road conditions or
traffic flow
You can minimise your vehicle's CO 2emis-
sions by driving carefully and having it serv-
iced regularly.
The vehicle will use more fuel than usual in the following situations:
R at very low outside temperatures
R in urban traffic
R on short journeys
R in mountainous terrain
R when towing a trailer
i Only for certain countries: you can find
the current consumption and emission val-
ues of your vehicle in the COC documents
(EU CERTIFICATE OF CONFORMITY). These documents are delivered with your vehicle.
The consumption figures were, in each
case, based on the currently applicable ver- sion:
R for vehicles that comply with standards
up to and including the EURO 4 standard,
in accordance with EU Directive
80/1268/EEC
R for vehicles that comply with or exceed
the EURO 5 standard, in accordance with Regulation (EC) No. 715/2007 Deviations from these values may occur
under normal operating conditions. AdBlue
®
Important safety notes AdBlue
®
is a water-soluble fluid for the
exhaust gas aftertreatment of diesel engines. It is:
R non-toxic
R colourless and odourless
R non-flammable
If you open the AdBlue ®
tank, small amounts
of ammonia vapour may be released.
Ammonia vapours have a pungent odour and
are particularly irritating to the skin, to
mucous membranes and to the eyes. You may experience a burning sensation in your eyes,
nose and throat. You may also experience
coughing and watery eyes.
Do not inhale any ammonia vapours that may
be released. Only fill the AdBlue ®
tank in well-
ventilated areas.
Low outside temperatures AdBlue
®
freezes at a temperature of approx-
imately -11 †. The vehicle is delivered from
the factory equipped with an AdBlue ®
pre-
heating system. Winter operation can thus be
guaranteed even at temperatures below
-11 †.
Additives !
Only use AdBlue ®
in accordance with ISO
22241. Do not use additives with AdBlue ®
and do not dilute AdBlue ®
with water. This
may destroy the BlueTEC exhaust gas after-
treatment system. 484
Service products and capacitiesTechnical data

Purity
!
Impurities in AdBlue ®
(e.g. due to other
service products, cleaning agents or dust)
lead to:
R increased emission values
R damage to the catalytic converter
R engine damage
R malfunctions in the BlueTEC ®
exhaust
gas aftertreatment system
Assuring the purity of AdBlue ®
is particularly
important with respect to avoiding malfunc-
tions in the BlueTEC exhaust gas aftertreat-
ment system.
If AdBlue ®
is pumped out of the AdBlue ®
tank,
e.g. during repair work, do not use this fluid to refill the tank. The purity of the fluid can no
longer be guaranteed.

Engine oil
General notes When handling engine oil, observe the impor-
tant safety notes on service products
(Y page 480).
The quality of the engine oil is decisive for the function and service life of an engine. After
extensive tests, Mercedes-Benz approves engine oils that correspond to the current
technical standard.
Therefore, only Mercedes-Benz approved
engine oils may be used in Mercedes-Benz
engines.
Further information on tested and approved
engine oils can be obtained from any
Mercedes-Benz Service Centre. Mercedes-
Benz recommends that you have the oil
change carried out at a qualified specialist
workshop. Mercedes-Benz approval is indica-
ted on the oil container by the inscription
"MB-Freigabe" or "MB-Approval" and the cor- responding designation, e.g. MB-Freigabe or
MB-Approval 229.51.
You can call up an overview of approved
engine oils on the Internet at
http://bevo.mercedes-benz.com by enter-
ing the designation, e.g. 229.5.
The table shows which engine oils have been
approved for your vehicle.
Petrol engines: in certain countries, differ-
ent engine oils can be used, provided that the
maintenance intervals are reduced. For more
information, please contact a qualified spe-
cialist workshop. Petrol engines MB-Freigabe
