Checking transmission oil level with oil level sensor
CAUTION!
Transmission damage!
If the oil level is too high or too low, this can result in
damage to the transmission.
X Make sure that the oil level never exceeds the “HOT-
FULL” or drops below the “HOT-ADD” marking of the
oil dip stick when the oil is at operating temperature.
X Please make sure that the operating panel display
displays “oL ok” (oil level is okay) in the oil level
mode.
X Use only authorised types of transmission oil.
The transmission is equipped with an oil level sensor. You can
read out the oil level and the oil level sensor errors on the
display in the operating panel for the transmission.
In order to read out the oil level without error, the following
conditions must be met:
z The MT is parked on level ground.
z The transmission is shifted into neutral N.
z The engine is running at low idle speed.
z The transmission output shaft stands still, i.e. the MT does
not move.
z The operating temperature has been reached (see engine
coolant temperature display in combination display
instrument).
z The transmission oil needs to settle, which means that the
MT has not moved for at least two minutes.
