How to Check Lubricant
To get an accurate reading, the vehicle should be
on a level surface.
If the level is below the bottom of the filler plug
hole, you may need to add some lubricant.
Add enough lubricant to raise the level to the
bottom of the filler plug hole.
What to Use
To determine what kind of lubricant to use see
