If the engine oil cannot be topped up under
the given conditions,
do not drive on! Stop
the engine and seek the professional assis-
tance of an Official Service, as this could
cause serious damage to the engine.

Wash your skin thoroughly if it comes into
contact with engine oil.
Coolant
General notes
The cooling system is factory-filled with an
anti-freeze product.
Coolant consists of a mixture of water and
40% anti-freeze additive. This mixture gives
the required anti-freeze protection at temper-
atures down to -25 °C (-13 °F) and protects
the cooling and heating system against cor-
rosion. It also prevents scaling and raises the
boiling point of the coolant considerably.
The coolant concentration must not be re-
duced by adding water, even in warmer sea-
sons or in warm countries. The concentration
of the anti-freeze additive in the coolant
must be at least 40 %.
If greater anti-freeze protection is required in
very cold climates, the proportion of the anti-
freeze additive can be increased, but only up
to 60% (anti-freeze protection down to ap-
proximately -40 °C (-40 °F)). Exceeding this
proportion reduces anti-freeze protection and
the cooling effect.
Coolant fluid with protection down to -35 °C
(-31 °F) is added at the factory in vehicles
destined for countries with a cold climate. In
these countries, the concentration of coolant
should always be kept above 50%.
The type of anti-freeze to be used for topping
up is indicated on the coolant tank cover

Fig.
112.
CAUTION
Anti-freeze that does not correspond to the
●
correct specification may particularly affect
corrosion protection considerably.
Faults caused by corrosion may lead to
●
coolant leaks. Risk of serious engine faults!
