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.
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).
i E10 fuel contains up to 10% bioethanol.
Your vehicle is E10-compatible. You can
refuel your vehicle using E10 fuel.
As a temporary measure, if the recommended
fuel is not available, you may also use regular
unleaded gasoline with an octane rating of
87 AKI/91 RON. This may reduce engine per-
formance and increase fuel consumption.
Avoid driving at full throttle and sudden accel-
eration. Never refuel using fuel with a lower
AKI.
Information on refueling ( Y
page 183).
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 suff icient. 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.
! Only use Ultra Low Sulfur Diesel (ULSD),
otherwise it may lead to increased wear
and damage to the fuel system, engine and
exhaust system.
! Do not use the following: R
gasoline R
diesel with a bio-diesel content greater
than 5% (e.g. B20) R
bio-diesel R
vegetable oil R
paraffin R
kerosene R
marine diesel R
heating oil
Do not mix such fuels with diesel fuel and
do not use any special additives. Other-
wise, engine damage may occur.
! In countries outside USA and Canada,
only use sulfur-free diesel with a sulfur con-
tent under 50 ppm. Otherwise, the emis-
sion control system could be damaged.
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.

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 †).
Additives
! Only use DEF in accordance with ISO
22241. Do not use additives with DEF and
do not dilute DEF with water. This may
destroy the BlueTEC exhaust gas after-
treatment system. Purity
! Impurities in DEF (e.g. due to other ser-
vice products, cleaning agents or dust) lead
to: R
increased emission values R
damage to the catalytic converter R
engine damage R
malfunctions in the BlueTEC exhaust gas
aftertreatment system
Assuring the purity of DEF is particularly
important with respect to avoiding malfunc-
tions in the BlueTEC exhaust gas aftertreat-
ment system.
If DEF is pumped out of the DEF tank, e.g.
during repair work, it must not be returned to
the tank. The purity of the fluid can no longer
be guaranteed.

Engine oil
General notes
! Never use engine oil or an oil filter of a
specification other than is necessary to ful-
fill the prescribed service intervals. Do not
change the engine oil or oil filter in order to
achieve longer replacement intervals than
those prescribed. You could otherwise
cause engine damage or damage to the
exhaust gas aftertreatment.
Follow the instructions in the service inter-
val display regarding the oil change. Other-
wise, you may damage the engine and the
exhaust gas aftertreatment.
When handling engine oil, observe the impor-
tant safety notes on service products
( Y
page 447).450

Technical data

The engine oils are matched to the perform-
ance of Mercedes-Benz engines and service
intervals. You should therefore only use
engine oils and oil filters that are approved for
vehicles with maintenance systems.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz Cen-
ter. Or visit the website
http://bevo.mercedes-benz.com.
The table shows which engine oils have been
approved for your vehicle.

! 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.Service products and filling capacities 451

On ly use brake fluid appr oved by Mercedes-
Benz according to MB Approval 331.0.
In formation about approved brake fluid can
be obtained at any qualif ied specialist work-
shop or on the In ternet at
http:/ /be vo.mercedes-benz.co m.
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.
Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB BeVo 310.1, e.g.
on the Internet at
http://bevo.mercedes-benz.com. Or con-
tact a qualified specialist workshop.
! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating. i Have the coolant regularly replaced at a
qualified specialist workshop and the
replacement confirmed in the Maintenance
Booklet.
Comply with the important safety precautions
for service products when handling coolant
( Y
page 447).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks: R
corrosion protection R
antifreeze protection R
raising the boiling point
If the coolant has antifreeze protection down
to -35 ‡( -37 †), the boiling point of the cool-
ant during operation is approximately 266 ‡
(130 †).
The antifreeze/corrosion inhibitor concentra
-
tio n in the engine cooling system should: R
be at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 ‡ (-37 †). R
not exceed 55% (antifreeze protection
down to -49 ‡ [-45 †]). Other wise, heat
will not be dissipated as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor concentrate in accord-
ance with MB Specifications for Service Prod-
ucts 310.1.
i When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
i The coolant is checked with every main-
tenance interval at a qualified specialist
workshop.452

Important safety notes
G WARNING
Windshield washer concentrate could ignite if
it comes into contact with hot engine compo-
nents or the exhaust system. There is a risk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
! Do not add distilled or de-ionized water to
the washer fluid container. Otherwise, the
level sensor may be damaged.
! Only MB SummerFit and MB WinterFit

of water and windshield washer fluid, e.g.
MB SummerFit.
Add 1 part MB SummerFit to 100 parts water. At temperatures below freezing: X
Fill the washer fluid reservoir with a mixture
of water and washer fluid, e.g. MB Winter-
Fit.
For the correct mixing ratio refer to the
information on the antifreeze reservoir.
i Add windshield washer fluid, e.g. MB
SummerFit or MB WinterFit, to the washer
fluid all year round.

Important safety notes The climate control system of your vehicle is
filled with refrigerant R ‑ 134a.
The instruction label regarding the refrigerant
type used can be found on the radiator cross
member.
! Only the refrigerant R ‑ 134a and the PAG
oil approved by Mercedes-Benz may be
used. The approved PAG oil may not be
mixed with any other PAG oil that is not
approved for R-134a refrigerant. Other-
wise, the climate control system may be
damaged.
Service work, such as topping up refrigerant
or replacing components, may only be carried
out by a qualified specialist workshop. All
applicable regulations must be adhered to,

Maximum gradient-climbing capabil-
ity
Note that the vehicle's gradient-climbing
capability depends on the off-road conditions
and the road surface conditions.456
Vehicle data for off-road driving
Technical data

Vehicles with the ON&OFFROAD package:
the maximum gradient climbing ability is
100% when the LOW RANGE off-road gear is
selected.
Vehicles without the ON&OFFROAD pack-
age: the maximum gradient climbing ability is
80%.
Accelerate carefully and make sure that the
wheels do not spin when driving on steep ter-
rain.
i If the load on the front axle is reduced
when pulling away on a steep uphill slope,
the front wheels have a tendency to spin.
4ETS recognizes this and brakes the
wheels accordingly. The rear wheel torque
is increased, making it easier to drive off.
For further information about the maximum
gradient climbing ability, see ( Y
page 202).
