Coolant and coolant additives can pollute the environment. Collect leaking operating fluids and
dispose of them properly in accordance with applicable environmental laws and regulations.

The engine cooling system is filled at the factory with a mixture of specially conditioned water and at
least 40percent of Volkswagen engine coolant additive G13 (TL-VW774J).
To protect the engine, the mixture must always contain at least 40% coolant additive even in warm
weather or climates where antifreeze protection is not needed.
If more antifreeze protection is needed for climate conditions, the percentage of coolant additive can
be increased. However, the coolant additive percentage must never be more than 60%; otherwise,
antifreeze protection is reduced and the ability of the mixture to cool the engine is also reduced.
The engine coolant additive is pink. The mixture of engine coolant additive and water provides an‐
tifreeze protection down to -13°F (-25°C). It also helps to protect the light alloy parts in the engine
cooling system against corrosion. In addition, the mixture helps prevent calcium deposits and in‐
creases the boiling point of the engine coolant.
When adding engine coolant, use a mixture of distilled water and at least 40% coolant additive -
G13 - or - G12plus-plus - (TL-VW 774 G) for optimum corrosion protection ⇒ .
Do not mix - G13 - with - G12plus - or - G11 -. Mixing these coolant additives together significantly
reduces corrosion protection ⇒ and can lead to engine damage that is not covered by any
Volkswagen Limited Warranty.
