Differential Gear Oil: Inspection

WARNING: This page is about a different car, the 2013 Subaru Forester. However, it is still accessible from the selected car via links, so may be relevant.

Park the vehicle on a level surface.
Remove the differential oil level gauge and wipe it clean.
Reinsert the level gauge all the way. Make sure the level gauge is inserted correctly and in the proper orientation.
Remove the oil level gauge again, and check the level of differential gear oil. If the differential gear oil level is below "L" line, add oil to bring the level up to "F" line.

NOTE: To prevent overfilling the differential gear oil, do not fill oil above the "F" line.
