12.3.24.2 Checking the oil level
NOTICE
The gearbox oil volume changes depending on the temperature
If the temperature rises, the volume increases. Where temperature di󹪜erences and 󹪝lling
quantities are signi󹪝cant, the volume di󹪜erence can amount to several liters.
The oil level must therefore be checked while still slightly warm, approximately 30minutes
after switching o󹪜 the drive unit.
