Attention! Draining oil from transmission units must be carried out on a warm vehicle, immediately after it has stopped. Beware of burns on the exhaust system of the car. Fill and add only grades of oils approved by BMW-AG. The type of oil filled is indicated on a sticker attached to the filling hole.
Change the gear oil of the BMW X5 E53 every 80,000 km during maintenance. At intervals, systematically check the oil level, which should be at the level of the lower edge of the filler hole. Perform a visual check for signs of leakage in visible areas, if necessary, to do this, remove the protection panel for auxiliary units and the stiffening plate.
