Check the engine coolant level after the

coolant if low
If the engine coolant level is correct or the
problem continues after adding coolant, do
not drive any farther. Contact an
authorized Volkswagen dealer or
authorized Volkswagen Service Facility.
These instructions apply only when the
coolant temperature stays in the normal

malfunction.
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.
When adding engine coolant, use a mixture of distilled water and at least 40% coolant additive G 13
or G 12 plus-plus (TL-VW G) for optimum corrosion protection ⇒ .
Do not mix G 13 with G 12 plus or G 11. Mixing these coolant additives together significantly reduces
corrosion protection ⇒ and can lead to engine damage that is not covered by any Volkswagen
Limited Warranty.
WARNING
Too little antifreeze protection in the engine cooling system can cause engine failure and
severe injuries.
x Always make sure there is enough of the correct coolant additive to provide proper
antifreeze protection at the coldest temperatures that can be expected where the vehicle will
be used.
x At extremely cold temperatures, the coolant could freeze, causing the vehicle to break
down. The heater would also not work, and vehicle occupants could be without protection at
subfreezing temperatures.
NOTICE
Never mix original Volkswagen engine coolant additives with other additives not approved by
Volkswagen. Mixing Volkswagen coolant additives with coolant additives made by other
manufacturers can seriously damage the engine and the engine cooling system.
x If the fluid in the engine coolant reservoir is any color but pink, then G 13 was mixed with a
different engine coolant. If this is the case, the engine coolant must be replaced immediately.
Otherwise serious malfunctions or engine damage can occur!
Engine coolant and engine coolant additives can pollute the environment. Collect leaking
operating fluids and dispose of them properly in accordance with applicable environmental laws and
regulations.
