Important safety notes on the refilling
procedure DEF is a water-soluble fluid for the exhaust
gas aftertreatment of diesel engines. It is:
R not poisonous
R colorless and odorless
R not flammable
When you open the DEF container, small
amounts of ammonia vapor may be released. Ammonia vapors have a pungent odor and are
particularly irritating to the skin, to mucous
membranes and to the eyes. You may expe-
rience a burning sensation in your eyes, nose and throat. Coughing and watering of the
eyes are possible.
Do not inhale ammonia vapors. Fill the DEF
tank only in well-ventilated areas.
DEF must not come into contact with your
skin, eyes or clothing and must not be swal-
lowed. Keep DEF away from children.
If you or other persons come into contact with
DEF, observe the following:
R Rinse DEF from your skin immediately with
soap and water.
R If DEF comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
R If DEF has been swallowed, rinse your
mouth out immediately. Drink plenty of
water. Seek medical assistance without
delay.
R Change out of clothing contaminated with
DEF immediately.
! Only use DEF in accordance with
ISO 22241. Do not mix any additives with
DEF, and do not dilute DEF with water. This
may destroy the BlueTEC exhaust gas after- treatment system.
! The vehicle must be parked on level
ground to fill the DEF tank. The DEF tank
can only be filled as intended with the vehi-
cle parked on a level surface. This avoids
false level readings. Filling the tank is not permitted if the vehicle is not parked on a
level surface. There is a danger of overfill-
ing, which could result in damage to com-
ponents of the BlueTEC exhaust gas after-
treatment.
! Rinse surfaces that have come into con-
tact with DEF immediately with water or
remove DEF using a damp cloth and cold
water. If the DEF has already crystallized,
use a sponge and cold water to clean it. DEF
residues crystallize after time and contam- inate the affected surfaces.
! DEF is not a fuel additive and must not be
added to the fuel tank. If DEF is added to
the fuel tank, this can lead to engine dam-
age.
For further information on DEF, see
(Y page 450).
You will find further information on DEF in the printed Operator's Manual under "Technical
data".

R
Gasoline with metalliferous additives
R Diesel
Do not mix such fuels with the fuel recom-
mended for your vehicle. Do not use addi-
tives. This can otherwise lead to engine
damage. This does not include cleaning
additives for the removal and prevention of residue build-up. gasoline may only be
mixed with cleaning additives recommen-
ded by Mercedes-Benz; see "Additives".
You can obtain further information from
any authorized Mercedes-Benz Center.
! To ensure the longevity and full perform-
ance of the engine, only premium-grade
unleaded gasoline must be used.
If standard unleaded gasoline is unavaila-
ble and you have to refuel with unleaded
gasoline of a lower grade, observe the fol-
lowing precautions:
R Only fill the fuel tank to half full with reg-
ular unleaded gasoline and fill the rest
with premium-grade unleaded gasoline
as soon as possible.
R Do not drive at the maximum speed.
R Avoid sudden acceleration and engine
speeds over 3,000 rpm.
Using mixtures of methanol and ethanol is not permitted. E10 fuel or E15 fuel (unleaded gas-
oline with 10% or 15% ethanol) can be used.
You will usually find information about the fuel
grade on the pump. If you cannot find the
label on the pump, ask the staff for assis-
tance.
i For further information, consult a quali-
fied specialist workshop or visit
http://www.mbusa.com (USA only).
All other models: as a temporary measure, if
the recommended fuel is not available, you
may also use regular unleaded gasoline with
an octane rating of 87 RON/91 MON. This
may reduce engine performance and increase fuel consumption. Avoid driving at full throttle
and sudden acceleration. Never refuel using
fuel with a lower AKI. Information on refueling (Y
page 186).
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 buildup. gasoline
must only be mixed with additives recom-
mended by Mercedes-Benz. Comply with
the instructions for use on the product
label. More information about recommen-
ded additives can be obtained from any
authorized Mercedes-Benz Center.
Mercedes-Benz recommends that you use
branded fuels 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
such cases, and in consultation with an
authorized Mercedes-Benz Center, the gaso-
line may be mixed with the cleaning additive
recommended by Mercedes-Benz. You must
observe the notes and mixing ratios specified
on the container.
Diesel Fuel grade
G
WARNING
If you mix diesel fuel with gasoline, the flash
point is lower than that of pure diesel fuel.
When the engine is running, exhaust system
components could overheat without being
noticed. There is a risk of fire.
Never refuel with gasoline. Never mix gasoline with diesel fuel.
! Refuel only using diesel fuel that con-
forms to European standard EN 590 or an
equivalent specification. Fuel that does not conform to EN 590 can lead to increased
wear and damage the engine and exhaust
system. Service products and filling capacities

!
Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R gasoline
R paraffin
R kerosene
Do not mix such fuels with diesel fuel and
do not use any special additives. This can
otherwise lead to engine damage.
! Vehicles with diesel particle filters:
in
countries outside the EU, only use low sul- fur Euro diesel with a sulfur content of
under 50 ppm. Otherwise, the emission
control system could be damaged.
! Vehicles without a diesel particle fil-
ter: in countries where only diesel fuel with
a high sulfur content is available, you will
need to carry out your vehicle's oil change
at shorter intervals. Further information on
oil change intervals can be obtained at a
qualified specialist workshop.
You will usually find information about the fuel
grade on the pump. If you cannot find the
label on the pump, ask the staff for assis-
tance.
Information on refueling (Y page 186).
Bio-diesel – FAME (fatty acid methyl ester) Mercedes-Benz USA approves the use of bio-diesel B5 for all BlueTEC diesel engines. The
concentration of bio-diesel in the ULSD may
not exceed 5% by volume.
Pure bio-diesel and diesel fuel with a higher
percentage of bio-diesel, such as B20, can
damage the engine and the fuel system. For
this reason, they are not approved.
For more information, consult the gas station
staff. The bio-diesel B5 label on the gasoline
pump must clearly state that the standard for ULSD has been fulfilled. If the label is not
clear, do not refuel the vehicle. Do not refuel your vehicle with fuels unless
they have been approved by Mercedes-Benz.
Information on refueling (Y page 186).
Low outside temperatures
i Diesel fuel with improved cold flow prop-
erties is available during the winter months.
Further information about fuel properties
can be obtained from oil companies, e.g. at gas stations. DEF
Important safety notes Comply with the important safety notes for
service products when handling DEF
(Y
page 447).
DEF is a water-soluble fluid for the exhaust
gas aftertreatment of diesel engines. It is:
R not poisonous
R colorless and odorless
R not flammable
When you open the DEF container, small
amounts of ammonia vapor may be released. Ammonia vapors have a pungent odor and are
particularly irritating to the skin, to mucous
membranes and to the eyes. You may expe-
rience a burning sensation in your eyes, nose and throat. Coughing and watering of the
eyes are possible.
Do not inhale ammonia vapors. Fill the DEF
tank only in well-ventilated areas.
Low outside temperatures DEF freezes at a temperature of approx-
imately 12 ‡(-11 †). The vehicle is delivered
from the factory equipped with a DEF pre-
heating system. Winter operation can thus be
guaranteed even at temperatures below 12 ‡
(-11 †). 450

Do not use any additives in the engine oil.
This could damage the engine.
Engine oil viscosity Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity, this means that it is thick; a low viscosity
means that it is thin.
Select an engine oil with an SAE classification (viscosity) suitable for the prevailing outside
temperatures. The table shows you which
SAE classifications are to be used. The low-
temperature characteristics of engine oils
can deteriorate significantly, e.g. as a result
of aging, soot and fuel deposits. It is therefore
strongly recommended that you carry out reg- ular oil changes using an approved engine oil
with the appropriate SAE classification. Brake fluid
G
WARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake fluid is too low, vapor pockets may form in the brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
Comply with the important safety notes for
service products when handling brake fluid
(Y page 447).
The brake fluid change intervals can be found
in the Maintenance 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-
shop or on the Internet at
http://bevo.mercedes-benz.com.
i Have the brake fluid regularly replaced at
a qualified specialist workshop and the
replacement confirmed in the Maintenance Booklet. Coolant
Important safety notes G
WARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine. 452
