Cadillac 2009 Escalade EXT - Manual (Page 429)

All-Wheel Drive
Transfer Case
If your vehicle is equipped with All-Wheel Drive, 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 7-4.
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.
