WARNING: The coolant reservoir is under pressure. Open only when the engine is cold.

CAUTION: Use only distilled water (DI water) for mixing coolant additives. Optimum corrosion protection can be reached only by using distilled water.

NOTE:

The vehicle be must level.

The water used for mixing greatly influences the effectiveness of the coolant. To meet water quality requirements, only distilled water is recommended when mixing with coolant.

Small quantities of coolant can be added. Use coolant system filler unit VAS 6096 if larger quantities of coolant are needed when filling.

Consult the owner's manual for the coolant system filler unit VAS 6096.

G12++ and G13 may be mixed with the G11, G12 and G12+ coolant additives. However, this can worsen the corrosion protection.

Perform the following:

-- When the engine is cold, check the coolant level via the markings -illustration- on the container.

Delivery service: Coolant level is above the MIN mark.
Inspection: Coolant level is above the MIN mark.

-- If the coolant level is too low: Fill using the required mixture ratio.

Freeze protection to	Coolant additive	Water
-13°F (-25°C)	approximately 40%	approximately 60%
-33°F (36°C)	approximately 50%	approximately 50%

NOTE: If there is a loss of fluid and this is not usage-related: Determine the cause and inform the customer. Repair measures.
