Additives
! Operatin gthe engin ewith fuel additives
can cause wear in the fuel high-pressure
pump and contaminate the entire fuel sys-
tem. The repair costs are high. This does
not include additives for the removal and
prevention of residue build-up. Petrol must
only be mixed with additives recommended
by Mercedes-Benz .More information about
recommended additives can be obtained
from any Mercedes-Benz Servic eCentre. One of the major problem
swith low-grade
fuel is the creation of carbon deposits during
the process of burnin gfuel. Mercedes-Benz
recommends that you use fuel brands that
have additives.
If you use fuels without these additives for a
longer period of time, there may be abuild-up
of carbon deposits. Thes ewill form especially
on the inlet valves and in the combustion
chamber.
This could lead to engine runnin gproblems,
e.g.:
R longe rengine warm-up phase
R uneven idle
R engine noise
R misfiring
R los so fpower
In areas where petrol with the required addi-
tives is not available, carbon deposits can
build up. In this case, Mercedes-Benz recom-
mends the use of additives that have been
approved for Mercedes-Benz vehicles; see
http:/ /bevo.mer cedes-benz.com.
The quality of the fuel available in some coun-
tries may not be sufficien t.Residue could
build up as aresult. In such cases, and in
consultation with aMercedes-Ben zService
Cent re,the petrol ma ybemixed with the
additive recommended by Mercedes-Benz
(part no. A000989254510). You must
observe the notes and mixin gratios specified
on the container.
Consult aMercedes-Ben zService Cent reto
view alist of approved products. Observe the
instruc tions for use in the product descrip-
tion.
Do not mix other fuel additives with fuel. This
causes unnecessary cost sand could damage

WARNING
If you mix diesel fue lwithp etrol, th eflash

pur ediesel 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 equivalen tquality .Fuel that does
not con form to EN 59 0can lead to
increased wear as well as damag etothe
engin eand exhaust sys tem.
! 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. This can
otherwis elead to engine damage .This
does not include flo wimprover additives.
For further information, se e"Flow improv-
ers".
! Vehicles with adiesel particle filter: in
countries outside the EU, only refuel with
low-sulphur Eur odiesel with asulphur con-
ten tunde r50p pm; otherwise the emission
contro lsystem could be damaged.
! Vehicles without adiesel particle fil-
ter: in countries where only diesel fuel with
ah igh sulphur conten tisavailable ,you will
need to carry out your vehicle' soil change
at shorter intervals. More information
abou tthe interval for oil change can be obtained from any qualified specialist
workshop.
Usually you will fin dinformation about the
fuel grade on the pump. If you cannot find the
labe lont he petrol pump, ask the filling sta-
tion staff.
Infor mation on refuelling (Y page 175).
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 avoide dbyrefuelling 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, dies elfue lfrom
warmer areas may not be suitabl efor opera-
tion in colder climat icconditions.
i Further informatio noncountry-specific
fuel properties can be obtained from oil
companies, e.g. at filling stations.
Flow imp rovers
To improve the low-temperatur eresistanc eof
diesel fuel, aflow improver can be attached.
The effec tiveness of aflow improver is not
guaranteed for every fuel.
Only use flow improvers tested and approved
by Mercedes-Benz. Durin guse, please
observe the information on operation.
Correc tdosage and sufficien tmixing are deci-
sive in improving low-temperature resistance
with the flow improver. Overdosage can
potentially even decrease low-temperature
resistanc eand must therefor ebeavoided.
Follo wthe manufacturer's guidelines on dos-
age.
Mix the additive int othe diesel in good time,
before the flo wcharacteristic softhe diesel
becom einsufficie nt.O therwise, malfunctions
can only be rectified by heating the entire fuel
system, e.g. by parking in aheated garage. 426

Engine oil viscosity Viscosit
ydescribes the flow characteristics
of afluid. If an engine oil has ahigh viscosity
rating, it flows slowly ;the lower the viscosity,
the faster it flows.
Engin eoil selection is based on the respective
outside temperatures and in accordance with
the SAE classification (viscosity). The table
shows you which SAE classifications 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 .Itistherefore
strongly recommended to observe regular oil
changes usin ganapproved engine oil with the
appropriate SAE classification. Brake fluid
G
WARNING
Over aperiod of time, the brak efluid absorbs
moisture from the air; This lowers its boiling
point.
If the boiling point of the brake fluid is too low,
vapour pocket smay form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This impairs braking effi-
ciency.
You shoul dhave 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 according to MB Approval 331.0.
Information about approved brake fluid can
be obtained at any qualified specialist work-
sho poront he Internet at

WARNING
Antifreeze is highly flammable. Fire, naked

yourself. Do not spill any antifreeze on hot
engine parts.
! Only add coolant that has been premixed

Otherwise, the engin ecooling system is not
sufficiently protected from corrosion and

! The engin ecooling system is filled with
coolant, which must be renewed after
15 years or after 250,000 kilometres at the
latest.
The coolant is amixtur eofw ater and anti-

following tasks:
R anti-corrosio nprotection
R antifreeze protection
R raising th eboiling point
If antifreeze/ corrosion inhibitor is presen tin

The antifreeze/ corrosion inhibitor concentra-
tion in the engin ecooling system should:
R be at least 50%. This will protect the engine
