The table shows which engine oils have been
approved for your vehicle.
Petrol engines: in certain countries, differ-
ent engine oils can be used, provided that the
maintenance intervals are reduced. For more
information, please contact a qualified spe-
cialist workshop.

Additives
!
Do not use any additives with 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 viscos-
ity rating, it flows slowly; the lower the vis-
cosity, the faster it flows.
Engine oil selection is based on the respec-
tive outside temperatures and in accordance
with the SAE classification (viscosity). The
table shows you which SAE classifications are
to be used. The low-temperature properties
of engine oils can be significantly impaired
during operation due to, for example, ageing
or soot and fuel accretion. It is therefore
strongly recommended to observe regular oil
changes using an approved engine oil with
the appropriate SAE classification.
Brake fluid
When handling brake fluid, observe the
important safety notes on service products
(
Y page 217).
The brake fluid change intervals can be found
in the Service 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 Service
Booklet.
Coolant
General notes
!
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 Specifications
for Service Products 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.
