Checking the oil level

NOTICE
The gearbox oil volume changes depending on the temperature
If the temperature rises, the volume increases. Where temperature differences and filling
quantities are significant, the volume difference can amount to several liters.
The oil level must therefore be checked while still slightly warm, approximately 30 minutes
after switching off the drive unit.
