The scale -2- is designed only for coolant additive -G 13-.

WARNING:

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

CAUTION:

Use only distilled water for mixing coolant additives. Optimum corrosion protection can be reached only by using distilled water.

NOTE:

The vehicle must level.

Refer to the Electronic Parts Information.(ETKA) for suitable freeze protections.

The water used for mixing greatly influences the effectiveness of the coolant. In order to have a coolant mixture for all countries, always use distilled water to mix the coolant in older models.

G12 ++ and G13 can also be mixed with coolant additives G11, G12 and G12+.

-- Check the coolant level in the reservoir when the engine is cold.

-- If the coolant level is too low: Add coolant according to the mixture ratio.

Delivery Inspection: Coolant level is above the MIN mark.

Inspection service: Coolant level is above the MIN mark.

NOTE:

Small quantities of coolant can be added. When larger quantities of coolant are needed when filling, the Cooling System Charge Unit:VAS 6096 should be used.

Consult the owner's manual for the Cooling System Charge Unit:VAS 6096 .

If there is a loss of fluid and this is not usage-related: Determine the cause and repair it (repair measure).
