that the wheel/tyre dimensions and tyre
type are correct.
When using an emergency spare wheel or
spare wheel of a different size, you must not
exceed the maximum speed of 80 km/h.
Snow chains must not be fitted to emergency
spare wheels. Points to remember
You should regularly check the pressure of
the emergency spare wheel, particularly prior
to long trips, and correc tthe pressure as nec-
essary (Y page 295). The value on the wheel
or as given in the "Technical data" section
(Y page 302) is valid.
i When you are driving with the emergency
spare wheel fitted, the tyre pressure loss
warning system cannot function reliably.
Only restart the tyre pressure loss warning
system when the defective wheel has been
replaced with a new wheel.
An emergency spare wheel may also be fitted
against the direction of rotation. Observe the
time restriction on use as well as the speed
limitation specified on the emergency spare

WARNING
Driving safety may be impaired if non-
approved parts, tyres and wheels or safety-
relevant accessories are used.
This could lead to malfunctions in safety-rel-
evant systems, e.g. the brake system. This
could cause you to lose control of your vehicle
and cause an accident.
Fo rthis reason, Mercedes-Ben zrecommends
that you use genuine Mercedes-Benz parts or
parts of equal quality. Only use tyres, wheels
and accessories that have been specifically
approved for your vehicle. H
Environmental note
Daimler AG also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. For these, the same war-
ranty applies as for new parts.

as control units and sensors for these
restraint systems, may be installed in the
following areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R dashboard
R instrument cluster
R centre console
Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint sys-
tems.
Have accessories retrofitted at a qualified
specialist workshop. Mercedes-Benz rec-
ommends that you use a Mercedes-Benz
Service Centre for this purpose.
Mercedes-Benz tests genuine parts and con-
version parts and accessories that have been
specifically approved for your vehicle for their
reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to evaluate other parts. Mercedes-
Benz accepts no responsibility for the use of
parts that have been independently or offi-
cially approved.
In Germany, certain parts are only officially
approved for installation or modification if
they comply with legal requirements. This
also applies to some other countries. All gen-
uine Mercedes-Benz parts meet the approval
requirements. The use of non-approved parts
may invalidate the vehicle's general operating
permit. 308

Fuel
Important safety notes G
WARNING
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine before refuelling. G
WARNING
Avoid contact with fuels.
It is hazardous to your health if your skin
comes into direct contact with fuels or you
breathe in fuel vapours.

Fuel grade
!
Do no tuse diesel to refuel vehicles with a
petrol engine. Even asmall quantity of die-
sel will damage the fuel injection system.
! Only refuel using unleaded, premium-
grade petrol with at least 95 RON/
85 MON that conforms to European stand-
ard EN 228 or E DIN 51626-1 or an equiv-
alent specification.
! Do not use the following:
R E85 (petrol with 85% ethanol)
R E100 (100% ethanol)
R M15 (petrol with 15% methanol)
R M85 (petrol with 85% methanol)
R M100 (100% methanol)
R Petrol with metallic additives
R Diesel
Do not mix fuels such as this with petrol
and do not use any additives. Doing so may
cause engine damage. This does not include additives for the removal and pre-
vention of residue build-up. Petrol must
only be mixed with additives recommended
by Mercedes-Benz. More informatio nabout
recommended additives can be obtained
from any Mercedes-Benz Service Centre.
Usually you 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.
i E10 fuel contains up to 10% bioethanol.
Your vehicle is suitable for use with E10
fuel. You can refuel your vehicle using E10
fuel.
i If the recommended fuel is not available,
but only as a temporary measure, you may
also use unleaded petrol with an octane
rating of 91 RON/82.5 MON. This may
reduce engine performance and increase
fuel consumption .Avoid driving at full
throttle.
The quality of the fuel available in some
countries may not be sufficient. Residue
could build up as a result. In such cases,
and in consultation with aMercedes-Benz
Service Centre, the petrol may be mixed
with the additive recommended by
Mercedes-Benz( part no.
A000989254510). You must observe the
notes and mixing ratios specified on the
container.
Information on refuelling (Y page 141).
Additives
! Do not refuel with low grade fuel and do
not use fuel additives that have not been
tested and approved for Mercedes-Benz
vehicles. Otherwise the fuel system could
malfunction or be damaged.
One of the major problems with low-grade
fuel is the creation of carbon deposits during
the process of burning fuel. Mercedes-Benz
recommends that you use fuel brands that
have additives. 312
Service products and capacitiesTechnical data

If you use fuels withou
tthese additives for a
longer period of time, there may be a build-up
of carbon deposits. These will form especially
on the inlet valves and in the combustion
chamber.
This could lead to engine running problems,
e.g.:
R longer engine warm-up phase
R uneven idle
R engine noise
R misfiring
R loss of power
In areas where petrol with the required addi-
tives is not available, carbon deposits can
build up. In this case, Mercedes-Ben zrecom-
mends the use of additives that have been
approved for Mercedes-Benzv ehicles; see
http://bevo.mercedes-benz.com.
Consult a Mercedes-Benz Service Centre to
view a list of approved products. Observe the
instructions for use in the product descrip-
tion.
Do no tmix other fuel additives with fuel. This
causes unnecessary costs and could damage
the engine.
Diesel (EN 590) Fuel grade
G
WARNING
Do not use petrol to refuel vehicles with a die-
sel engine. Do not mix diesel with petrol. This
would result in damage to the fuel system and
engine, which could lead to a vehicle fire.
! When refuelling, only use diesel fuel that
conforms to the European standard EN 590
or is of equivalen tquality. Fuel that does
not conform to EN 590 can lead to
increased wear as well as damage to the
engine and exhaust system.
! Do no tuse the following:
R marine diesel
R heating oil R
bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not mix these fuels with diesel fuels and
do not use any special additives. Other-
wise, this can lead to damage to the engine.
This excludes flow improver; see "Low out-
side temperatures".
! Vehicles with adiesel particle filter: in
countries outside the EU, only refuel with
low-sulphur Euro diesel with a sulphur con-
ten tunde r50p pm; otherwise the emission
control system could be damaged.
! Vehicles without adiesel particle fil-
ter: in countries where only diesel fuel with
a high sulphur conten tis available, you will
need to carry out your vehicle's oil change
at shorter intervals. More information
aboutt he interval for oil change can be
obtained from any qualified specialist
workshop.
Usually you 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.
i For more information, contact a qualified
specialist workshop.
Information on refuelling (Y page 141).
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 climati cconditions. Service products and capacities
313Technical data Z

i
Further information on country-specific
fuel properties can be obtained from oil
companies, e.g. at filling stations.
Flow improver
To improve the low-temperature resistance of
diesel fuel, a flow improve rcan be attached.
The effectiveness of a flow improve ris not
guaranteed for every fuel.
Only use flow improvers tested and approved
by Mercedes-Benz.D uringuse, please
observe the information on operation.
Correct dosage and sufficient mixing are deci-
sive in improving low-temperature resistance
with the flow improver. Overdosage can
potentially even decrease low-temperature
resistance and must therefore be avoided.
Follow the manufacturer's guidelines on dos-
age.
Mix the additive into the diesel in good time,
before the flow characteristics of the diesel
become insufficient. Otherwise, malfunctions
can arise through heating the fuel system,
e.g. through parking in a heated garage.
More information aboutr ecommended flow
improvers can be obtained from any qualified
specialist workshop.
Notes on fuel consumption 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 efficien tuse of the fuel by the engine
R driving style
R other non-technical factors, such as envi-
ronmental influences or road conditions
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 version:
R for vehicles up to and including the EURO
4s tandard, in accordance with EU Direc-
tive 80/1268/EEC
R for vehicles above the EURO 5standard,
in accordance with Regulatio n(EC) No.
715/2007
Deviations fro mthese values may occur
under normal operating conditions. Engine oil
Points to remember The quality of the engine oil is decisive for the
function and service life of an engine. After
extensive tests, Mercedes-Ben
zapproves
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-
Ben zrecommends that you have the oil
change carried out at a qualified specialist
workshop. Mercedes-Benza pproval is indica-
ted on the oil container by the inscription "MB
Approval" and the corresponding designa-
tion, e.g. MB Approval 229.51. 314

Additives
!
Do not use additives in engine oil. This
could damage the engine. Engine oil viscosity
Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity
rating, it flows slowly; the lower the viscosity,
the faster it flows.
Engine oil selection is based on the respective
outside temperatures and in accordance with
the SAEc
lassification (viscosity). The table
shows you which SA Eclassifications are to be
used. The low-temperature properties of
engine oils can be significantly impaired dur-
ing operation due to, for example, ageing or
soot and fuel accretion. It is therefore
strongly recommended to observe regular oil
changes using an approved engine oil with the
appropriate SA Eclassification. Brake fluid
G
WARNING
Over a period of time, the brake fluid absorbs
moisture fro mthe air; This lowers its boiling
point.
If the boiling point of the brake fluid is too low,
vapour pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This impairs braking effi-
ciency.
You should have the brake fluid renewed at
regular intervals. The brake fluid change inter-
vals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz.I nformation abou tapproved brake fluid
