Risk of damage to the transmission!
If the oil level is too low or too high, this can lead to malfunctions and
transmission damage.
Check the oil level at the correct intervals. Do not actuate the Intarder im-
mediately before you check the oil level. The oil level in the housing cannot
be correctly adjusted in this case.
