The cooling system is filled at the factory with the correct amount of anti-
freeze for the country concerned.
In most cases, the mixture consists of 60% water and 40% antifreeze. This
mixture gives the required antifreeze protection at temperatures down to
-25 °C and particularly protects the metal parts of the cooling system
against corrosion. It also prevents scaling and significantly raises the boil-
ing point of the coolant fluid.
Countries with warm climate
The coolant fluid concentration must not be reduced by adding plain water,
even in the summer or in warm climates. The concentration of the antifreeze
must always be at least 40%.
Countries with cold climate
If greater freeze protection is required in very cold climates, the proportion
of antifreeze G12++ can be increased. A concentration of 60% offers anti-
freeze protection of temperatures down to approx. - 40 °C. However, the
concentration of antifreeze must not exceed 60%, as the antifreeze protec-
tion would then drop and the performance of the coolant system would suf-
fer.
Vehicles for countries with cold climates (e.g. Sweden, Norway and Finland)
have factory-filled antifreeze protection for temperatures down to -35 °C. In
these countries, the concentration of antifreeze should always be at least
50%.
CAUTION
● It is advisable to have the cooling system checked before the winter sea-
son to make sure that the antifreeze concentration is adequate for the con-
ditions to be expected. This applies particularly if you intend to take the ve-
hicle into a colder climate zone. If necessary, have the antifreeze concentra-
tion increased to 50 - 60% as required.
● Use only G12++ antifreeze, an additive meeting the “TL-VW 774G” speci-
fication. Other antifreezes may give considerably inferior corrosion protec-
tion. The damage caused by the use of these antifreezes may lead to a loss
of coolant fluid, causing serious damage to the engine.
● G12++ antifreeze can only be mixed with antifreeze additives G11, G12
and G12+. 
Checking the coolant level
The coolant level can be checked visually.

Radiator fan
The radiator fan can start running spontaneously.
The auxiliary fan can continue to run for as long as 10 minutes after stop-
ping the engine, even after the ignition is switched off. It may also start run-
ning suddenly ⇒ 
after some while if
● Stored heat raises the coolant temperature, or
● The hot engine compartment is additionally heated up by the sun.
WARNING
When working in the engine compartment be aware that the radiator fan
may start running suddenly, leading to the risk of injury.
 Washer fluid and windscreen wiper blades
Windscreen washer system
Plain water is not sufficient for the windscreen washer sys-
tem.
Fig. 169 In the engine
compartment: Cap of
windscreen washer fluid
reservoir.
The container for the windscreen washer contains the cleaning fluid for the
windscreen and the headlight washer system*. The container is located in
the engine compartment (front left). The filler cap is marked with the symbol
 ⇒ fig. 169.
The capacity of the container is listed in ⇒ page 290.
Plain water on its own is not enough to clean the glass properly. It is there-
fore advisable to add a suitable washer fluid additive (with wax solvent) to
the water. A washer fluid with freeze-resistant additive should be used in
winter. 
