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
then disposed of properly and in an environmentally responsible way.
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.

NOTICE

standard 501 14 is available from Volkswagen dealerships.
If this brake fluid is not available and it is necessary to use another high-quality brake fluid instead,
brake fluid that is compliant with DIN ISO 4925 CLASS 4 or US standard FMVSS 116 DOT 4 can be
used.
Not all brake fluids that are compliant with DIN ISO 4925 CLASS 4 or US standard FMVSS 116 DOT 4
have the same chemical composition. Some of these brake fluids may contain chemicals that can
damage or destroy brake system components over time.
Volkswagen therefore recommends the use of brake fluid that is compliant with VW standard 501 14
to ensure sustained proper operation of the brake system.
Brake fluid that is compliant with VW standard 501 14 fulfils the requirements of DIN ISO 4925
CLASS 4 or US standard FMVSS 116 DOT 4.
Brake fluid level
The brake fluid level must always be between the MIN and MAX marking on the brake fluid reservoir
or above the MIN marking
The brake fluid level cannot be checked accurately in all models as engine components may partially
conceal the fluid level in the brake fluid reservoir. If the brake fluid level cannot be read exactly,
please go to a qualified workshop.
The brake fluid level drops slightly during vehicle operation as the brake pads wear and the brakes
are automatically adjusted.
Brake fluid level
The indicator lamp lights up red.
Brake fluid level is too low.
Do not drive on! Check the brake fluid level.
If the brake fluid level is too low, inform a qualified workshop. Have the brake system checked.
Changing the brake fluid
The brake fluid should be changed by a qualified workshop. Volkswagen recommends using a
Volkswagen dealership for this purpose. Only brake fluid that conforms with the required
specification should be used.

WARNING
Brake failure or reduced braking efficiency can be caused by the brake fluid level being too low or by
brake fluid that is too old or unsuitable.

Location of the 12-volt vehicle battery
The 12-volt vehicle battery is located in the engine compartment.
Explanation of the warnings on the 12-volt vehicle battery
Always wear eye protection!Electrolyte is very corrosive and caustic. Always wear
protective gloves and eye protection!Fire, sparks, naked lights and smoking are prohibited!
A highly explosive mixture of gases is given off when the 12-volt vehicle battery is charging!
Always keep children away from electrolyte and the 12-volt vehicle battery!Always
observe the owner's manual!

WARNING
Any work on the 12-volt vehicle battery and the electrical system can cause serious chemical burns,
fire or electric shocks. Always read and observe the following warnings and safety information
before carrying out any kind of work:
