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

WARNING:

The Coolant Reservoir Is Under Pressure. Open It 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.

Approved frost protection additives: refer to the appropriate service information.

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 coolant level is too low: fill with coolant mixture.

Delivery inspection: coolant level is above the MIN mark.

NOTE:

Small Quantities Of Coolant Can Be Refilled When Larger Quantities Of Coolant Are Needed When Filling, Cooling System Filling Equipment :VAS 6096 should be used.

Consult the Operating Instructions that come with the coolant system filler unit:VAS 6096 .

Determine cause of fluid loss which cannot be attributed to normal use and rectify (repair measure).
