Gasoline
Fuel grade
! Do not use diesel to refuel vehicles with a
gasoline 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 could
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 premium grade
gasoline with at least 91 AKI/95 RON.
i E10 fuel contains up to 10% bioethanol.
Your vehicle is E10-compatible. You can
refuel your vehicle using E10 fuel.
! Only use the fuel recommended. Operating
the vehicle with other fuels can lead to engine
failure.
! Do not use the following: R
E15 (gasoline with 15% ethanol) R
E85 (gasoline with 85% ethanol) R
E100 (1 00% ethanol) R

Technical data

R
Gasoline with metalliferous additives R
Diesel
Do not mix such fuels with the fuel recom-
mended for your vehicle.
! To ensure the longevity and full perform-
ance of the engine, only premium-grade
unleaded gasoline must be used.
If standard unleaded gasoline is unavailable
and you have to refuel with unleaded gasoline
of a lower grade, observe the following pre-
cautions: R
Only fill the fuel tank to half full with regular
unleaded gasoline and fill the rest with pre-
mium-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 assistance.
i For further information, consult a qualified
specialist workshop or visit
http://www.mbusa.com (USA only).
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 acceleration.
Never refuel using fuel with a lower AKI.
Information on refueling ( Y
page 144).
Additives
i In some countries, the available gasoline
may not be sufficiently low in sulfur. This fuel
can temporarily produce unpleasant odors,
especially on short journeys. As soon as sul-
f ur -free fuel (sulfur content <1 0 ppm) is used
for refueling, the odors are reduced. Engine oil
General notes
! Never use engine oil or an oil filter of a spec-
ification other than is necessary to fulfill the
prescribed service intervals. Do not change
the engine oil or oil filter in order to achieve
longer replacement intervals than those pre-
scribed. You could otherwise cause engine
damage or damage to the exhaust gas after-
treatment.
Follow the instructions in the service interval
display regarding the oil change. Otherwise,
you may damage the engine and the exhaust
gas aftertreatment.
When handling engine oil, observe the important
safety notes on service products ( Y
page 331).
The engine oils are matched to the performance
of Mercedes-Benz engines and service intervals.
You should therefore only use engine oils and oil
filters that are approved for vehicles with main-
tenance systems.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz Center.
Or visit the website
http://bevo.mercedes-benz.com.
The table shows which engine oils have been
approved for your vehicle.

Ad ditives
! Do not use any additives in the engine oil.
This could damage the engine.
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 ser-
vice products when handling brake fluid
( Y
page 331).
The brake fluid change intervals can be found in
the Maintenance Booklet.
Only use brake fluid approved by Mercedes-
Benz in accordance with MB-Freigabe or MB-
Approval 331.0.
Information about approved brake fluid can be
obtained at any qualified specialist workshop or
on the Internet at
http://bevo.mercedes-benz.co m.
i Have the brake fluid regularly replaced at a
qualified specialist workshop and the replace-
ment 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 Ser-
vice Products, MB BeVo 310.1, e.g. on the
Internet at http://bevo.mercedes-benz.com.
Or contact 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 replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety precautions
for service products when handling coolant
( Y
page 331).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the fol-
lowing 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 coolant
during operation is approximately 266 ‡
(130 †).334
Service products and filling capacities
Technical data

The antifreeze concentrate/corrosion inhibitor
concentration 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 †]). Otherwise, heat will not be
dissipated as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor concentrate in accordance
with MB Specifications for Service Products
310.1.
i When the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze and corrosion protection.
i The coolant is checked with every mainte-
nance interval at a qualified specialist work-
shop.
