When to Check Lubricant
Refer to the Maintenance Schedule
to determine how often to check the
lubricant. See Scheduled
Maintenance on page 11 3.
How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.
Vehicle Care
If the level is below the bottom of
the filler plug hole, some lubricant
will need to be added. 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 Recommended Fluids and
Lubricants on page 11 8 to
determine what kind of lubricant
to use.
