relevant gear.
i If the engine exceeds the maximum
engine speed when shifting down, the auto-
matic transmission protects against engine
damage by not shifting down.
i If the maximum engine speed for the shift
range is reached and you continue to accel-
erate, the automatic transmission shifts up
in order to prevent the engine from over-
revving, even if the shift range is restricted.

Important safety notes
G
Risk of explosion
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine and the auxiliary heating
before refuelling. G
Risk of injury
Do not come into contact with fuels.
It is hazardous to your health if your skin
comes into direct contact with fuels or you
breathe in fuel vapours. G
Risk of fire
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.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel vehicles with a petrol engine. Even a small
quantity of the wrong fuel will damage the
fuel system and engine.
! Do not switch on the ignition if you acci-
dentally refuel with the wrong fuel. Other-
wise, the fuel will enter the fuel lines. Notify
a qualified specialist workshop and have
the fuel tank and fuel lines drained com-
pletely. Petrol (EN 228)
Fuel grade !
Only refuel using unleaded premium-
grade petrol with at least
95 RON/85 MON, which conforms to Euro-
pean standard EN 228 or an equivalent
specification.
! Do not use the following:
R E85 (petrol with 85 % ethanol)
R E100 (100 % ethanol)
R M15 (petrol with 15 % methanol) 142
RefuellingDriving and parking

R
M85 (petrol with 85 % methanol)
R M100 (100 % methanol)
R diesel
Do not mix these fuels with petrol and do
not use any special additives. Otherwise,
this can lead to damage to the engine. This
does not include additives for the removal
and prevention of residue build-up on the
inlet valves.
! Use a filter when adding fuel from a fuel
can. The fuel lines and/or the diesel injec-
tion system could otherwise be blocked by
particles from the fuel can.
i If the recommended fuel is not available,
but only as a temporary measure, you may
also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.
In some countries, the fuel grade available
may not be adequate and could cause res-
idue to build up around the inlet valves. In
such cases, and in consultation with a
Mercedes-Benz Service Centre, the petrol
may be mixed with the additive recommen-
ded by Mercedes-Ben z(part no.
A000989254510). You must observe the
notes and mixing ratios specified on the
container.
For further information on "Fuel", see
(Y page 319).
AMG vehicles !
Only refuel using super-grade unleaded
petrol with at least 98 RON/88 MON,
which conforms to European standard EN
228 or equivalent.
You can otherwise impair engine output or
damage the engine.
i If the recommended fuel is not available
and only as a temporary measure, you may
also use premium-grade unleaded petrol,
95 RON/85 MON. This may reduce engine performance and increase fuel consump-
tion. Avoid driving at full throttle.
! In emergencies, and only when the rec-
ommended fuel is not available, you may
also use standard unleaded petrol,
91 RON/82.5 MON.
However, using this fuel results in consid-
erably higher petrol consumption and sig-
nificantly reduced engine performance.
Avoid driving at full throttle.
If no fuel other than regular petrol with
91 RON/82.5 MON or a lower grade is per-
manently available, you should have the
vehicle adapted to run on this fuel by the
local after-sales service centre.
CLS 350 BlueEFFICIENCY !
Only refuel using unleaded, sulphur-free
premium-grade petrol with at least
95 RON/85 MON, which conform stoEuro-
pean standard EN 228 or an equivalent
specification.
You can otherwise impai rengine outpu tor
damage the engine.
i In some countries, the available petrol
may not be sufficiently low in sulphur. This
fuel can temporarily produce unpleasant
odours, especially on short journeys. As
soon as sulphur-free fuel (sulphur content
<10p pm) is used for refuelling, the odours
are reduced. Diesel (EN 590, DIN 51628)
Fuel grade !
Only refuel with diesel that conforms to
European standard EN 590 or German
standard DIN 51628 or equivalent. You can
otherwise impair engine output or damage
the engine.
! Vehicles with diesel particle filters: in
countries outside the EU, only use low sul-
phur Euro diesel with a sulphur conten tof Refuelling
143Driving and parking Z

under 50 ppm
.Otherwise, the emission
control syste mcould be damaged.
! Vehicles without adiesel particle fil-
ter: the engine oil should be changed more
frequently in countries in which diesel with
a higher sulphur conten tis available. More
information about intervals for changing
the engine oil can be obtained from any
Mercedes-Benz Service Centre.
! Using fuel that does not conform to Euro-
pean standard EN 590 or German standard
DIN 51628 can lead to increased wear,
engine damage and damage to the 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 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".
! Use a filter when adding fuel from a fuel
can. Otherwise, the fuel lines and/or the
diesel injection system could be blocked by
particles from the fuel can.
For further information on "Fuel", see
(Y page 319).
Low outside temperatures Diesel fuel with improved cold flow qualities
is available during the winter months. In
Europe, various climate-dependent low-tem-
perature classes are defined in EN 590. Refu-
elling with diesel fuel which complies with the
climatic specifications of standard EN 590
can help to prevent operating problems. At
exceptionally low temperatures, it is possible that the flow properties of the fuel may be
inadequate. This also applies to fuel that has
not been adapted to suit the climatic condi-
tions, e.g. diesel fuel from warmer regions.
i
Further information about country-spe-
cific fuel properties can be obtained from
oil companies, e.g. at filling stations.
Flow improver Flow improvers can be added to improve the
cold resistance of diesel fuel. The effective-
ness of a flow improver is not guaranteed with
every fuel.
Correct dosage and thorough mixing are deci-
sive factors in ensuring improvement in low-
temperature resistance. Under certain cir-
cumstances, an excessive dosage may
actually decrease low-temperature resist-
ance and should therefore be avoided.F ollow
the manufacturer's dosing instructions.
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become inadequate. Malfunctions can other-
wise only be rectified by heating the entire
fuel system, e.g. by parking the vehicle in a
heated garage.
Observe the information provided by the man-
ufacturer when using a flow improver. Only
use flow improvers that have been tested and
approved by Mercedes-Benz. You can obtain
further information from any Mercedes-Benz
Service Centre. Refuelling
