Mercedes-Ben
zrecommends that you use
fuel brands that have the additives.
The quality of the fuel available in some
countries may not be sufficient. Residue
could build up as a result. In such cases, and
in consultation with an authorized Mercedes-
BenzC enter, the gasoline may be mixed with
the cleaning additive recommended by
Mercedes-Benz (part no. A000989254512).
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
specification other than is necessary to
fulfill the prescribed servic eintervals. Do
not change the engine oil or oil filter in
order to achieve longe rreplacement
intervals than those prescribed. You could
otherwise cause engine damage or damage
to the exhaust gas aftertreatment.
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 333).
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 maintenance
systems.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz
Center .Orvisit the website
http://bevo.mercedes-benz.com.
The table shows which engine oils have been
approved for your vehicle. Model Engine

Use only SAE 0W-40 or SAE 5W-40 engine oils
for AMG vehicles.

Do not use any additives in the engine oil.
This could damage the engine.
Engine oil viscosity 336
Service products and filling capacitiesTechnical data

Viscosity describes the flow characteristics
of a fluid.Ifane
ngine oil has a high viscosity,
this means tha titis 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
regularo il changes using an approved engine
oil with the appropriate SA Eclassification. Brake fluid
G
WARNING
The brake fluid constantly absorbs moisture
fro mt he 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.
When handling brake fluid, observe the
important safety notes on service products
(Y page 333).
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
workshop 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
components in the engine compartment, it
may ignite. There is a risk of fire and injury.
Let the engine cool down before you add
antifreeze. Make sure that antifreeze is not
spilled next to the filler neck.T horoughly
clean the antifreeze from components before
starting the engine.
! Only add coolant that has been premixed
with the desired antifreezep rotection. You
could otherwise damage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB Specifications for
Service Products 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
replacement confirmed in the Maintenance
Booklet.
Comply with the important safety precautions
for service products when handling coolant
(Y page 333).
The coolant is a mixture of water and
antifreeze/corrosion inhibitor. It performs
the following tasks:
R corrosio nprotection
R antifreeze protection
R raising the boiling point
If the coolant has antifreeze protection down
