Draining the coolant for the high-temperature coolant circuit

WARNING: Hot fluids. 
Risk of scalding! 
  • Conduct all work in the vehicle wearing appropriate personal protective equipment only.
CAUTION: Materials harmful to health. 
Contact with fluids harmful to health! 
  • Note and follow safety instructions on containers.
  • Conduct all work in appropriate personal protective equipment only.
NOTE: TECHNICAL INFORMATION 
See NOTES FOR WORKING ON THE COOLING SYSTEM .
NOTE: 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.
NOTE: 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.
NOTE: TECHNICAL INFORMATION 
Collect and dispose of emerging fluids. Observe country-specific waste disposal regulations.
