TECHNICAL INFORMATION
Immobilization period-long fill of coolant!
Do not reuse used coolant.
The coolant must be replaced when replacing and removing components which depend on the anti-corrosion effect of the coolant. The cooling system must therefore be emptied and refilled.
In the case of other removal work involving the draining of part quantities of coolant, the coolant level must be topped up with new coolant.

TECHNICAL INFORMATION
Filling without the vacuum filling equipment (watering can filling) is not permitted .
Failure to observe these instructions may result in component or engine damage.
The filling specification must be observed.
It is essential to visually check the vacuum filling equipment before use to check that it is functioning correctly and clean.
It is not permissible to operate the vehicle if the filling procedure has not been fully completed. Otherwise there may be functional limitations (degradation) or overheating.
A bleeding procedure is required after a part has been exchanged in the cooling system and/or after refilling the cooling system.
