Mixture Ratio
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2010 Volkswagen Jetta, 2009 Volkswagen Jetta, 2009 Volkswagen GLI, 2008 Volkswagen Jetta, and 2008 Volkswagen GLI. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Use tap water for mixing. Well water does not have the necessary quality to assure the functionality of the coolant.

NOTE:
Coolant additive G 12+ and G 12++ prevent freezing and corrosion damage, scaling and also raise the boiling point of the coolant. For these reasons, the cooling system must be filled with radiator freeze and corrosion protection fluid all year round.
Especially in countries with tropical climates or when vehicle is driven under heavy load, the coolant improves the engine reliability by its increased boiling point.
The coolant concentration must not be reduced by adding water, even during the warmer season. The coolant additive ratio must be at least 40%.
