You should only carry out work on the cooling system if you know exactly how to perform the required tasks, are aware of the general
safety procedures and have access to the correct equipment, service fluids and suitable tools. Failing to carry out work correctly can
cause serious injuries → . Have all work carried out by a suitably qualified workshop if necessary. Volkswagen recommends using an
authorised Volkswagen repairer.
WARNING
Coolant is toxic. Contact with coolant, and especially ingestion of coolant, can cause serious or fatal injuries.
● Seek medical attention immediately after swallowing coolant.
● Seek medical attention if you have health problems after working with coolant.
● Always keep coolant out of the reach of children and only in the original sealed container.
● Never store coolant in empty food containers, bottles or any other non-original containers as people finding these containers may
then drink the coolant.
● Avoid regular contact with coolant to avoid damaging the skin.
● Protect skin, face and especially eyes while working with coolant.
● Do not eat, drink or smoke when working with coolant.
● Wash your skin with soap and water after working with coolant.
WARNING
Coolant can freeze at extremely cold outside temperatures, causing the vehicle to break down. This can lead to the heating no longer
working in the vehicle. Vehicle occupants with inadequate winter clothing could freeze to death.
● Make sure that the quantity of coolant additive is adjusted to the lowest expected ambient temperature at which the vehicle will
be operated.
● Use only coolant additives that have been approved by the manufacturer.
Coolant and coolant additives can pollute the environment.
● Collect any service fluids that escape or are spilled and dispose of them in a proper and environmentally responsible
manner.
The cooling system is filled at the factory with a mixture of specially prepared water and at least 40% coolant additive G12evo (TL 744-
L).
The proportion of coolant additive must always be at least 40% to protect the cooling system. If greater frost protection is required in
very cold climates, the proportion of anti-freeze additive can be increased. However, the percentage of coolant additive should not
exceed 55 %, as this would reduce the frost protection and the cooling effect.
The coolant additive is dyed a violet colour. The mixture of water and a coolant additive offers anti-freeze protection down to around
-25°C (around -13°F), protects the alloy parts in the cooling system against corrosion, prevents limescale deposits and significantly
increases the boiling point of the coolant.
When refilling the coolant, a mixture of distilled water and at least 40% of the coolant additive G12evo must be used in order to obtain
the optimum corrosion protection →
.
NOTICE
The colour of the coolant results from mixing the violet coolant additive with distilled water. If the liquid in the coolant expansion
tank is not violet but brown, for example, the suitable coolant has been mixed with another unsuitable coolant. This can result in
serious malfunctions or damage to the drive and cooling system.
● Use only coolant additives that have been approved by the manufacturer.
● Have the coolant replaced immediately by a suitably qualified workshop if it has a brown colour. Volkswagen recommends using an
authorised Volkswagen repairer.
● When adding coolant additives, never mix genuine coolant additives with other coolant additives that have not been approved by
Volkswagen.
