Chevrolet 2006 Equinox, Owner'S Manual, Page: 291 / 390

To get an accurate reading, the vehicle should be on a
level surface.
The proper level is from 0 to 3/8 inch (0 to 10 mm)
below the bottom of the filler plug hole.
If the level is below the bottom of the filler plug hole,
located on the rear axle, you’ll need to add some
lubricant. Add enough lubricant to raise the level to the
bottom of the filler plug hole.
What to Use
See Recommended Fluids and Lubricants on page 6-12
for the type of fluid to use.
