   Information 

   • The filling capacities are guidelines that can deviate slightly. This depends, for example, on the oil temperature and the length of time since the vehicle was driven. 
8. Read off the actual value.

   The oil level must be > 50 millimeters in order to be able to start the engine without possible subsequent damage! 

   • "Min" oil level approx. 50 mm 
   • "Max" oil level approx. 80 mm 
   • Oil level approx. 110 mm = overfilled
