Methods and systems for evacuating lubricant from an area of an axle are described. The lubricant may be evacuated away from one or more clutches during low temperatures so that a clutch may be engaged while having to displace less lubricant to engage the clutch. In one example, an electric machine may be rotated to evacuate lubricant away from the clutch.
