1) Filler hole
2) Drain hole
3) Oil level
Remove the plug from the filler hole and check the oil
level. The oil level should be kept even with the bottom
of the filler hole. If the oil level is below the bottom
edge of the hole, add oil through the filler hole to raise
the level.
If the vehicle requires frequent refilling, there
may be an oil leak. If you suspect a problem,
have the vehicle checked at your SUBARU deal-
er.
