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

Petrol
Fuel grade
! Do not use diesel to refuel vehicles with a
petrol engine. Do not switch on the ignition if you accidentally refuel with the wrong
fuel. Otherwise, the fuel will enter the fuel
system. Even small amounts of the wrong
fuel can result in damage to the fuel system
and the engine. Notify a qualified specialist
workshop and have the fuel tank and fuel
lines drained completely.
! Only refuel using unleaded petrol with at
least 95 RON that conforms to the Euro-
pean standard EN 228 or E DIN 51626-1 or
an equivalent specification.
Fuel of this specification may contain up to 10% ethanol. Your vehicle is suitable for use
with E10 fuel. You may refuel your vehicle
using E10 fuel.
Fuel that does not conform to EN 228 or
E DIN 51626–1 can lead to increased wear
as well as damage to the engine and
exhaust system. i
E10 fuel contains up to 10% bioethanol.
Your vehicle is suitable for use with E10
fuel. You may refuel your vehicle using E10 fuel.
! Only use the fuel recommended. Operat-
ing the vehicle with other fuels can lead to
engine failure.
! Do not use the following:
R E85 (petrol with 85% ethanol)
R E100 (100% ethanol)
R M15 (petrol with 15% methanol)
R M30 (petrol with 30% methanol)
R M85 (petrol with 85% methanol)
R M100 (100% methanol)
R Petrol with additives containing metal
R Diesel
Do not mix such fuels with the fuel recom-
mended for your vehicle.
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.
As a temporary measure, if the recommended
fuel is not available, you may also use regular unleaded petrol with an octane rating of
91 RON. This may reduce engine perform-
ance and increase fuel consumption. Avoid
driving at full throttle and sudden accelera-
tion. Never refuel using fuel with a lower RON.
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
<1 0 ppm) is used for refuelling, the odours
are reduced.
Information on refuelling (Y page 204).
GLC 300 4MATIC ! Only refuel using super unleaded petrol
with at least 98 ROZ, if you want maximum
performance from the engine. Alterna-
tively, you can also use unleaded petrol of
at least 95 ROZ. 482
Service products and capacitiesTechnical data

As a temporary measure, if the recommen-
ded fuel is not available, you may also use
regular unleaded petrol with an octane rat-
ing of 91 ROZ. Doing so results in higher
fuel consumption and significantly reduced performance. Never refuel using fuel with a lower RON.
Fuel of this specification may contain up to
10% ethanol.
Fuel that does not conform to EN 228 or
E DIN 51626–1 can lead to increased wear
as well as damage to the engine and
exhaust system.
Additives ! Operating the engine with fuel additives
added later can lead to engine failure. Do
not mix fuel additives with fuel. 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. Observe the instruc-
tions for use in the product description.
More information about recommended
additives can be obtained from any
Mercedes-Benz Service Centre.
Mercedes-Benz recommends that you use
fuel brands that have additives.
The quality of the fuel available in some coun- tries may not be sufficient. Residue could
build up in the injection system as a result. In
this case, in consultation with a Mercedes-
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 a risk 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 conform to EN 590 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.
! In countries outside the EU, only use low-
sulphur Euro diesel with a sulphur content
of under 50 ppm. Otherwise, the emission
control system could be damaged.
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.
Information on refuelling (Y page 204).
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. Service products and capacities

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:
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
