Index

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 fuel pump. If you cannot find the
label on the fuel pump, ask the gas station staff.
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 reduc e engin e per -
formance an d increas e fuel consump tion. Avoid
driving at full throttle and sudden acc ele ration.
Ne ver refuel using gasoline with a lower AKI.
Information on refueling ( Y
page 139).
CLS 400, CLS 400 4MATIC
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-
fur-free fuel (sulfur content <1 0 ppm) is used
for refueling, the odors are reduced.
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 preven-
tion of residue buildup. gasoline must only be
mixed with additives recommended by
Mercedes-Benz. Comply with the instructions
for use on the product label. More information
about recommended additives can be
obtained from any authorized Mercedes-Benz
Center. Mercedes-Benz recommends that you use bran-
ded fuels that have additives.
The fuel quality available in some countries may
not be sufficient. Residue could build up in the
fuel injection system as a result. In such cases,
and in consultation with an authorized
Mercedes-Benz Center, the fuel may be mixed
with the cleaning additive recommended by
Mercedes-Benz. You must observe the notes
and mixing ratios specified on the container.
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 323).
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.

approved for your vehicle.Service products and filling capacities 325

Use only SAE 0W-40 or SAE 5W-40 engine oils
for Mercedes ‑ AMG vehicles.
i MB approval is indicated on the oil contain-
ers.
Filling capacities The following values refer to an oil change
including the oil filter.

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 323).
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 notes for ser-
vice products when handling coolant
