Prepare the vacuum filling equipment according to the diagram.

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 danger 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.

Close the lid (1) of the coolant expansion tank (low temperature coolant circuit).

Start bleeding routine.

• Open the bleeder screw on the coolant expansion tank for the high-temperature coolant circuit and close it again after approx. 10 s.
• The bleeder screw may be closed before the 10 s have elapsed when coolant emerges.
• Adjust the fill level in the coolant expansion tank of the high-temperature coolant circuit to the maximum mark.
• Close the sealing cap (1) on the coolant expansion tank of the high-temperature coolant circuit.
• Connect the battery charger.
• Close driver's seat belt.
• Turn on ignition by quickly operating the START-STOP button three times.

• Hold idle speed for 30 s.
• Actuate the accelerator pedal to approximately 3500 rpm and hold the engine speed for 10 s. The cooling system bleeding procedure has finished approximately 11 min after the engine starts. The engine speed drops to the idle speed again.
• Let the engine warm up at idle until the coolant has reached a temperature of 100°C. The temperature display in the instrument cluster (KOMBI) is in the center position.
• Actuate the accelerator pedal to approximately 3500 rpm and hold the engine speed for 10 s.
• Hold idle speed for 30 s.
• Actuate the accelerator pedal to approximately 3500 rpm and hold the engine speed for 10 s.

• Actuate the accelerator pedal to approximately 3500 rpm and hold the engine speed for 10 s.
• Hold idle speed for 30 s.
• Actuate the accelerator pedal to approximately 3500 rpm and hold the engine speed for 10 s.
• Switch off engine.
• Allow the engine to cool down.
• Adjust the fill level in the coolant expansion tank of the high-temperature coolant circuit to 100 ml above the maximum mark.
