The specified temperatures of the SAE clas-
sification always refers to that of fresh oil. The
temperature characteristics of the engine oil
may deteriorate significantly as a result of
ageing during vehicle operation, especially at
low outside temperatures.
If the SAE classification of the engine oil is not
suitable for the outside temperature, change
the engine oil, in particular before the cold
season commences. Use only an approved
engine oil of the specified SAE classification.
Notes on brake fluid
Observe the notes on service products
(

WARNING
The brake fluid continuously absorbs mois-
ture from the air. This results in the boiling
point of the brake fluid lowering. If the boiling
point of the brake fluid is too low, vapour
pockets may form when the brakes are sub-
jected to a heavy load. This would impair brak-
ing efficiency. There is a risk of an accident.
Have the brake fluid renewed at the prescri-
bed intervals.
!
Brake fluid corrodes paint, plastic and rub-
ber. If brake fluid comes into contact with
paint, plastic or rubber, rinse with water
immediately.
Have the brake fluid regularly replaced at a
qualified specialist workshop.

Notes on coolant
Observe the notes on service products
(

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.
Service products
Let the engine cool down before you top up
the antifreeze. 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. Other-
wise you could damage the engine.
!
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.
!
Take care not to spill any coolant on painted
surfaces. You could otherwise damage the
paintwork.
Have the coolant regularly replaced at a quali-
fied specialist workshop.

The percentage of corrosion inhibitor/anti-
freeze additive in the engine cooling system:
at least 50 % (antifreeze protection down to
R
approximately -37 °C)
maximum 55 % (antifreeze protection down to
R
-45 °C)
Notes on washer fluid

WARNING
If windscreen washer concentrate comes into
contact with hot components of the engine or
the exhaust system, it can ignite. There is a
risk of fire and injury.
Make sure the windscreen washer concen-
trate does not come into contact with the filler
neck.
!
Use only washer fluids that are suitable for
lamp lenses, e.g. MB SummerFit or MB Win-
