If the engine oils listed in the table are not
available, you may add a maximum of 1.0 l
of the following engine oils, once only, until
the next oil change:

Additives
! Do not use additives in 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.
Engine oil selection is based on the respective
outside temperatures and in accordance with
the SAE classification (viscosity). The table
below shows you which SAE classifications
are to be used. The low-temperature proper-
ties of engine oils can be significantly
impaired during operation due to, for exam-
ple, 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.
21 Restriction: only use SAE 0W-40/SAE 5W-40 engine oils.

Brake fluid
G
WARNING
The brake fluid constantly absorbs moisture
from the air; this lowers its boiling point.
If the boiling point of the brake fluid is too low,
vapour pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This would impair braking
efficiency.
You should have the brake fluid renewed at
regular intervals. The brake fluid change inter-
vals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz. Information about approved brake flu-
ids can be obtained from any Mercedes-Benz
Service Centre.
i
There is usually a notice in the engine
compartment to remind you when the next
brake fluid change is due.
Coolant
Important safety notes
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
anti-corrosion protection
R
antifreeze protection
R
raising the boiling point
R
i
When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants and on fill-
ing can be found in the Mercedes-Benz
