Add differential oil so that the oil level is between 0 to 5 mm (0 to 0.197 in.) from the bottom lip of the differential filler plug hole.

NOTICE:

1. Too much or too little oil will lead to differential problems.
   
2. After changing the oil, drive the vehicle and then check the oil level again.
