Checking the coolant level and refilling coolant
Do not work on the cooling system unless you are familiar with the task, aware of the general safety 
procedures and have the correct equipment, service fluids and suitable tools. Serious injuries can be 
caused by carrying out work incorrectly 
workshop if you are uncertain. Volkswagen recommends using a Volkswagen dealership for this 
purpose.

ct coolant additive used must be sufficient for the lowest 
ambient temperature that you expect the vehicle to be exposed to. 
Vehicle occupants with inadequate winter clothing could then freeze to death as the heating will 
also no longer function. 
 
Coolant and coolant additives can pollute the environment. Spilt service fluids must be collected

Coolant specification 
First read and observe the introductoryinformation and safety warnings
The cooling system is filled at the factory with a mixture of specially prepared water and at least 40% 
coolant additive G 13 (TL-VW 774 J). 
The proportion of engine 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 60%, as this would 
reduce the frost protection again and the cooling effect.
