ENVIRONMENTAL NOTE
P ollution of the
environment due to irresponsible disposal
of operating Ouids Incorrect disposal of operating
Ouids can
cause consider
able damage to the environ-
ment. 
Dispose of operating Ouids in an en
viron-
mentally responsible manner. Operating Ouids
include t
he following:
= fuels
= DeNOx agent AdBlue n
for exhaust gas aser-
treatment
= lubricants
= coolant
= Brake Ouid
= windscreen washer Ouid
= climate control system refrigerant
Only use products approved by Mercedes-Benz.
Damage caused by the use of products that have
not been approved is not covered by the
Mercedes-Benz warranty or goodwill gestures. The operating Ouids
appr
oved by Mercedes-Benz
can be identiNed by the following inscriptions on
the container:
= MB-Freigabe (e.g. MB-Freigabe 229.51)
= MB-Approval (e.g. MB-Approval 229.51)

WARNING Risk of Nr
e or explosion from
fuel
Fuels are highly Oammable. 
Fire, naked Oames, smoking and cr
eating
sparks must be avoided. 
Before and during refuelling, switch oM
t

he vehicle and, if Ntted, the stationary
heater. &
WARNING Risk of injur
y from fuels
Fuels are poisonous and hazardous to your
healt
h. 
Do not swallow fuel or let it come into
cont

act with skin, eyes or clothing. 
Do not inhale fuel vapour. 
Keep children away from fuel. 
Keep doors and windows closed during
t

he refuelling process.
If you or other people come into contact with
fuel, obser
ve the following: 
Immediately rinse fuel oM y
our skin with
soap and water. 
If fuel comes into contact with your eyes,
immediat
ely rinse them thoroughly with
clean water. Seek medical attention
immediately. 
If you swallow fuel, seek medical atten-
tion immediat

ely. Do not induce vomit-
ing. Technical data
391


Change immediately out of clothing that
has come int o contact with fuel. Flexible-fuel vehicles can be refuelled with the fol-
lo

wing fuel types:
= unleaded petrol
= E85 fuel
= a mixture of E85 fuel and unleaded petrol
Flexible-fuel vehicles can be identiNed by the
Ethanol up to E85 sticker on the inside of the fuel
Nller Oap.
Depending on the country, the fuels you can use
in your vehicle may diMer from the information in
the Owner's Manual. The fuels that have been
approved for your vehicle can be found on the
instruction label on the inside of the fuel Nller Oap. Fuel

NOTE Damag
e caused by the wrong fuel Even small amounts of the wrong fuel could
r

esult in damage to the fuel system, the
engine and the emission control system. 
Only refuel using unleaded, sulphur-free
spar
k-ignition engine fuel that conforms
to European EN 228, or an equivalent
speciNcation.
Fuel of this speciNcation ma
y contain up to
10% ethanol by volume. Your vehicle is suita-
ble for use with E10 fuel. 
See the information label in fuel Nller Oap
f
or other compatible fuels .
Never refuel with one of the following fuels: = Diesel
= R

egular petrol with an octane number
lower than 91 RON
= Petrol with more than 3% methanol by vol-
ume, e.g. M15, M30
= Petrol with additives containing metal If you have accidentally refuelled with the
wr

ong fuel: 
Do not switch on the vehicle. 
Consult a q
ualiNed specialist workshop. The following compatibility indications for fuel
appl

y to your vehicle: 1
For petrol with a maximum of 5% ethanol by
v
olume
2 For petrol with a maximum of 10% ethanol by
v
olume
The compatibility indications for fuel on the vehi-
cle accor
ding to European standard EN 16942 392
Technical data

can be found on the information label on the fuel
Nller Oap or on t
he fuel dispenser or pump nozzle
suitable for your vehicle throughout Europe.
If the available fuel is not suPciently low in sul-
phur, it may produce unpleasant odours.
The recommended octane number for your vehi-
cle can be found on the information label on the
fuel Nller Oap.
If the recommended fuel is not available, you may
also temporarily use regular unleaded petrol with
an octane number of at least 91 RON. This may
reduce engine output and increase fuel consump-
tion.
Never refuel using petrol with an even lower RON.
Further information on fuel can be obtained at a
Nlling station or a qualiNed specialist workshop.
Information on additives in petrol (vehicles with
petrol engine)
Observe the notes on operating Ouids
( page 390). *
NOTE Damag e from use of unsuitable
additives Even small amounts of the wrong additive may
lead t
o malfunctions occurring. 
Only add cleaning additives recommen-
ded b

y Mercedes-Benz to the fuel. Mercedes-Benz recommends that you use brand-
name fuels wit

h additives.
In some countries, the fuel available may not have
suPcient additives. Deposits could build up in the
fuel injection system as a result. In this case, in
consultation with a Mercedes-Benz service
centre, mix the fuel with the cleaning additive rec-
ommended by Mercedes-Benz. Observe the notes
and mixing ratios indicated on the tank.
Information on fuel quality for vehicles with a die-
sel engine
General notes
Observe the notes on operating Ouids
(  page 390). &
WARNING Risk of Nr
e from fuel mixture
If you mix diesel fuel with petrol, the Oash
point of t
he fuel mixture is lower than that of
pure diesel fuel. 
Never refuel using petrol in diesel
engines. 
Never mix petrol with diesel fuel. *
NOTE Damag
e caused by the wrong fuel Even small amounts of the wrong fuel could
r

esult in damage to the fuel system, the
engine and the emission control system.
Vehicles with a diesel particulate Nlter: 
Only refuel using sulphur-free diesel fuel
t

hat conforms to European standard
EN 590, or an equivalent speciNcation.
In countries without sulphur-free diesel
fuel, refuel using only low-sulphur diesel
fuel with a sulphur content less than
50 ppm.
Vehicle without diesel particulate Nlt
er: Technical data
393


Only refuel using diesel fuel with a sul-
phur cont
ent less than 500 ppm.
Never refuel with one of the following fuels: = P

etrol
= Marine diesel
= Heating oil
= Pure fatty acid methyl ester or vegetable
oil
= ParaPn or kerosene
If you have accidentally refuelled with the
wrong fuel: 
Do not switch on the vehicle. 
Consult a q
ualiNed specialist workshop.The following compatibility indications for fuel
appl

y to your vehicle: 1
For diesel fuel with a maximum of 7% fatty
acid me
thyl ester by volume (bio-diesel)
2 For diesel fuel with a maximum of 10% fatty
acid me
thyl ester by volume (bio-diesel)
According to European standard EN 16942 you
can Nnd t

he compatibility indications at the fol-
lowing locations:
= On the vehicle on the information label on the
fuel Nller Oap ( page 183)
= On the fuel dispenser or pump nozzle suitable
for your vehicle throughout Europe Information on low outside temperatures
R

efuel your vehicle with as much winter diesel fuel
as possible at the beginning of winter.
Before changing over to winter diesel fuel, the fuel
tank should be empty, if possible. When Nrst refu-
elling with winter diesel fuel, keep the fuel level
low, e.g. to reserve level. The fuel tank can be Nl-
led as usual when next refuelling.
Further information on fuel can be obtained at a
Nlling station or a qualiNed specialist workshop.

AdBlue n
is a water-soluble Ouid for the NOx
exhaust gas asertreatment of diesel engines.
It may be improper or punishable in some coun-
tries to operate a vehicle that uses no AdBlue n
or
one that does not comply with the speciNcations
of this Owner's Manual.
* NOTE Malfunctions due t
o the dilution of
AdBlue n
or the use of additive-enhanced
AdBlue n The function of the NOx exhaust gas
aser

treatment can be impaired by the use of
unsuitable denoxiNcation agents. 
Only use AdBlue n
in accor
dance with
ISO 22241. 
Do not dilute AdBlue n
wit

consum

The average AdBlue n
consumption is between 1%
and 5% of fuel consumption. Like fuel consump-
tion, AdBlue n
consumption is highly dependent
upon driving style and operating conditions. For
this reason, your vehicle's actual consumption Ng-
ures in day-to-day operating conditions may diMer
from the consumption Ngures calculated. The fre-
quency at which you will have to top up AdBlue n
will also vary. Have the AdBlue n
supply checked
at a qualiNed specialist workshop before making
journeys outside Europe. Before a longer stay out-
side Europe, consult a qualiNed specialist work-
shop. AdBlue

ange and Nll level
The AdBlue n
Nll level and range can be displayed
via the on-board computer. The AdBlue n
range
shown depends strongly on the driving style and
operating conditions. The actual range may there-
fore deviate from the range currently displayed on
the on-board computer. The information supplied
in the Owner's Manual regarding the reserve
quantity at the Nrst display warning and the mini-
mum top-up quantity when the fuel tank is empty
is also to be understood as guide values. Engine oil
