Venting the low-temperature cooling system
NOTE:
TECHNICAL INFORMATION
Following maintenance work, no coolant may be present in the injector shafts or spark plug shafts.
If necessary, blow out the injector shafts or spark plug shafts using compressed air.

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.

TECHNICAL INFORMATION
Before starting the automatic cooling system bleeding procedure, make sure that both coolant circuits are filled . The cooling system bleeding procedure is automatically started simultaneously for both coolant circuits. If the cooling system bleeding procedure is started while one of the coolant circuits is empty, there is a risk of damage to the electric coolant pump when running it dry.
Make sure that terminal 15 is not disconnected for the bleeding procedure. Switch on low-beam headlights and hazard warning lights. If the low-beam headlights and hazard warning lights are not switched on, the ignition (terminal 15) will switch off automatically after a certain period of time and interrupt the bleeding procedure.

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.

- Remove the vacuum filling equipment from the coolant expansion tank of the low-temperature coolant circuit.
- Adjust the coolant level in the coolant expansion tank of the low-temperature coolant circuit to the maximum mark.
- Close the sealing cap (1) on the coolant expansion tank of the low-temperature coolant circuit.
- Close the engine compartment lid.
- Activate testing-analysis-diagnosis (PAD) by quickly pressing the START-STOPPING button three times.
- Activate the low beams and the hazard-warning lights at the same time
.
If the low beams and the hazard-warning lights are not turned on, the ignition (terminal 15 ) turns off automatically after a while and interrupts the bleeding procedure.
- Set the heating to the maximum temperature and the blower to the lowest level.
- Depress the accelerator pedal and hold for 15 s.
The automatic cooling system bleeding procedure is initiated.
After about 11 min, the cooling system bleeding procedure is ended automatically.
- Start engine.
The idle speed is automatically increased to 1200 RPM .
- Allow the engine to cool down.
- Adjust the fill level in the coolant expansion tank of the low-temperature coolant circuit up to the maximum mark.
