Cadillac 2006 Escalade EXT, Owner'S Manual, Page: 361 / 484

All-Wheel Drive
Transfer Case
Be sure to perform the lubricant checks described in
this section. There are two additional systems that
need lubrication.
When to Check Lubricant
Refer to the Maintenance Schedule to determine
how often to check the lubricant. See Scheduled
Maintenance on page 6-4.
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,
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. 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 6-12.
