4.4 Motor oil and oil filter

Oil level check

- Useaclean,lint-freecloth

The oil level must be measured with oil warm from operation (approx. 80 °C [176 °F]) and with the motor at a standstill. Measurements with cold oil are not meaningful.Thedesiredmotortemperatureisachievedafteradrivingtimeofapprox.10minutesat4000-4500U/min[RPM].

Measurement with a motor warm from operation is necessary, becausethe oil volume changes depending on the temperature. To avoid mistakenmeasurements,thevehiclemustbelevel.
