How to Check Lubricant
(A) Drain Plug (B) Filler Plug
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 will need to add some lubricant. Add enough
lubricant to raise the level to the bottom of the filler
plug hole. Use care not to overtighten the plug.
What to Use
Refer to the Maintenance Schedule to determine
what kind of lubricant to use. See Recommended
Fluids and Lubricants on page 511.
