When to Check and Change Lubricant

Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change it. 
See “Scheduled Maintenance Services” in the Index.

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,
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” in the Index.
