Engine compartmentMaintenance and care

!
Do not park up the vehicle for an extended
period straight after cleaning it, particularly after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for afew minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked up.
Regular care of your vehicle is acondition for
retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz. Washing the vehiclea
nd cleaning the
paintwork

lock. Do not open the driver's door or
front-passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park position P
automaticallya nd locks the wheels. You
can prevent this by shifting the auto-
matic transmission to Nbeforehand.
R Vehicles with DIRECT SELECT lever and
KEYLESS-GO:
do not open the driver's door or front-
passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park position P
automaticallya nd locks the wheels.
! If the key is within the rear detection
range of KEYLESS-GO, situations such as
the following could lead to the uninten-
tional opening of the boot lid/tailgate:
R using acar wash
R using ahigh-pressure cleaner
Make sure that the key is at least 3maway
fro mt hevehicle.
Observe th efollowing to mak esure that the
automatic transmission on vehicles with
DIRECT SELECT stays in position N:
X Make sure th evehicle is stationar yand the
ignitio nisswitche doff.
X Turn th ekey to position 2(Y page 179) in
th ei gnitio nlock.

Mercedes-Ben
zrecommends that you use
fuel brands that have additives.
The quality of the fuel available in some coun- tries may not be sufficient. Residuec ould
build up in the injection system as aresult. In
this case, in consultation with aMercedes-
Benz Service Centre, the petrol may be mixed with the cleaning additive recommended by
Mercedes-Benz. Always observe the notes
and mixing ratios specified on the container.
Diesel Fuel grade
G
WARNING
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is arisk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.
! When refuelling, only use diesel fuel that
conforms to the European standard EN 590
or is of equivalent quality. Fuel that does
not conformtoEN5 90 can lead to
increased wear as well as damage to the
engine and exhaust system.
! Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not mix such fuels with diesel fuel and
do not use any special additives. Other-
wise, engine damage may occur.
! Vehicles with diesel particle filters:
in
countries outside the EU, only use low sul-
phur Euro diesel with asulphurc ontent of under 50 ppm
.Otherwise, the emission
control system could be damaged.
! Vehicles without
adiesel particle fil-
ter: in countries where only diesel fuel with
ah igh sulphurc ontent is available, you will
need to carry out your vehicle's oil change
at shorter intervals. More information
about the interval for oil change can be
obtained from any qualified specialist
workshop.
Usuallyy ou will find information about the
fuel grade on the pump. If you cannot find the
label on the petrol pump, ask the filling sta-
tion staff.
Information on refuelling (Y page 201).
Low outside temperatures
In winter months, diesel fuel with an improved
cold flow quality is available. In Europe, the
EN 590 standard defines various climate-
dependent temperature categories. Malfunc- tions can be avoided by refuelling with diesel
fuel that corresponds to the climatic specifi-
cations outlined in EN 590. At unusually low
outside temperatures, it is possible that the
flow characteristics of the diesel fuel could be insufficient .Accordingly, diesel fuel from
warmer areas may not be suitable for opera-
tion in colder climatic conditions.
i Further information on country-specific
fuel properties and fuel types with low-tem-
perature resistance can be obtained from
oil companies, e.g. at filling stations.
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: 476
Service products and capacitiesTechnical data

R
efficien tuse 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 atrailer
i Only for certain countries: you can find
the curren tconsumption 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 4standard,
in accordance with EU Directive
80/1268/EEC
R for vehicles that comply with or exceed
the EURO 5standard, in accordance with
Regulation (EC) No. 715/2007
Deviations from these values may occur
under normal operatin gconditions. AdBlue

eproduct swhen handling AdBlue ®
(Y page 473). AdBlue
®
is aw ater-soluble fluid for the
exhaust gas aftertreatmen tofdiesel 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 apungent odour and
are particularly irritating to the skin ,to
mucous membranes and to the eyes. You may experience aburning 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 outsid etemperatures AdBlue

freezes at atemperature 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 destro ythe BlueTEC exhaust gas after-
treatment system.
