Ignition is switched off.

WARNING: Hot surfaces .
Risk of burning!

Perform all work only on components that have cooled down.

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
Follow notes for repair work on the cooling system.
For additional information see:
17 00 NOTES FOR REPAIR WORK ON THE COOLING SYSTEM

NOTE: TECHNICAL INFORMATION
Immobilization period-long fill of coolant!
Do not reuse used coolant.
When replacing and removing components which rely on the corrosion protection effect of the coolant, it is essential to change 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
Filling without the vacuum filling equipment (watering can filling) is not permitted .
If this is not observed, there is a risk of component damage 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
Collect and dispose of emerging fluids. Observe country-specific waste disposal regulations.

NOTE: TECHNICAL INFORMATION
When the engine is stopped after the completion of trip, it may be necessary to run the electric fan. In rare cases, operation of the electric fan can last up to 11 min. This protects the components. In this case, replacing the electric fan will not remedy the problem!
