4. Go to the "Maintenance/Repair" menu and press [F12] again.
5. Select the Oil Fill function and press [F12].
6. Start the engine and run until the oil temperature reaches 90°C, accelerating if necessary.
7. The oil level measurement will start automatically as soon as temperature is reached.
8. Stop the engine.

10. Finally, remove the tester.
