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. 
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
fuel t
hat 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.
Never refuel with one of the following fuels:
= diesel
= regular petrol with an octane number
lower than 91 RON
= petrol with more than 10% ethanol by vol-
ume, e.g. E15, E20, E85, E100
= petrol with more than 3% methanol by vol-
ume, e.g. M15, M30
= petrol with additives containing metal 428
Technical data

If you have accidentally refuelled with the
wr ong fuel: 
do not switch on the ignition. 
consult a q
ualiNed specialist workshop. The following compatibility indications for fuel
appl

y to your vehicle: 1
For petrol with maximum 5% ethanol by vol-
ume
2 For petrol with maximum 10% ethanol by vol-
ume According to European standard EN 16942 you
can Nnd
t

he compatibility indications at the fol-
lowing locations:
= on the instruction label on the fuel Nller Oap
= on the fuel pump or pump nozzle suitable for
your vehicle throughout Europe
If the available fuel is not suPciently low in sul-
phur, this can produce unpleasant odours.
The recommended octane number for your vehi-
cle can also be found on the instruction label in
the fuel Nller Oap ( page 217).
As a temporary measure, if the recommended fuel
is not available, you may also use regular unlea-
ded petrol with at least 91 RON. This may reduce
engine output and increase fuel consumption.
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 427). *
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.

sel engine

&
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: 
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 217)
= On the fuel dispenser or pump nozzle suitable
for your vehicle throughout Europe 430
Technical data

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

-
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
h water. 
Do not use additive-enhanced AdBlue n

AdBlue
n
residues crystallise aser a period of
time, and contaminate the surfaces with which
they come into contact. Clean the dirty surfaces
with water as soon as possible.
When you open the AdBlue n
tank, small amounts
of ammonia vapour may escape. Do not inhale
any ammonia vapours that may be released. Only
Nll the AdBlue n
tank in well-ventilated areas.

consum
ption
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 nwill also vary. Have the AdBlue
n
suppl
y 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 n
range and Nll level
You can have the AdBlue n
range and level dis-
played on the driver's display.
% The AdBlue n
r
ange shown depends strongly
on the driving style and operating conditions.
The actual range therefore may deviate from
the range currently displayed on the driver's
display.
The information supplied in the Owner's Manual
r
egarding the reserve quantity at the Nrst warning
on the driver's display and the minimum top-up
quantity when the AdBlue n
tank is empty is also
to be understood as guide values. Engine oil

WARNING Risk of an accident due t
o
vapour pockets forming in the brake sys-
tem
The brake Ouid cons
tantly absorbs moisture
from the air. This lowers the boiling point of
the brake Ouid. If the boiling point is too low,
vapour pockets may form in the brake system
when the brakes are applied hard.
This impairs the braking eMect. 
Have the brake Ouid r
enewed at the
speciNed intervals. Have the brake
Ouid r
egularly replaced at a quali-
Ned specialist workshop.
Only use a brake Ouid appr
oved by Mercedes-
Benz according to MB-Freigabe or MB-Approval
