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, located on the transfer case, you'll need to
add some lubricant. Add enough lubricant to
raise the level to the bottom of the filler plug hole.
A fluid loss could indicate a problem; check
and have it repaired, if needed.
What to Use
Refer to the Maintenance Schedule to determine
what kind of lubricant to use. See Recommended
Fluids and Lubricants on page 432.
