across the torso.
Safety belt maintenance
Inspect the safety belt systems periodically to make sure they work
properly and are not damaged. Inspect the safety belts to make sure
there are no nicks, tears or cuts. Replace if necessary. All safety belt
assemblies, including retractors, buckles, front safety belt buckle
assemblies, buckle support assemblies (slide bar-if equipped), shoulder
belt height adjusters (if equipped), shoulder belt guide on seatback (if
equipped), child safety seat LATCH and tether anchors, and attaching
hardware, should be inspected after a collision. Ford Motor Company
recommends that all safety belt assemblies in use in vehicles involved in
a collision be replaced. However, if the collision was minor and a
qualified technician finds that the belts do not show damage and
continue to operate properly, they do not need to be replaced. Safety
belt assemblies not in use during a collision should also be inspected and
replaced if either damage or improper operation is noted.
Failure to inspect and if necessary replace the safety belt
assembly under the above conditions could result in severe
personal injuries in the event of a collision.
For proper care of soiled safety belts, refer toInteriorin theCleaning
chapter.

Engine oil and filter recommendations
Look for this certification
trademark.
Use SAE 5W-20 engine oil.
Only use oils “Certified For Gasoline Engines” by the American
Petroleum Institute (API). An oil with this trademark symbol conforms
to the current engine and emission system protection standards and fuel
economy requirements of the International Lubricant Standardization and
Approval Committee (ISLAC), comprised of U.S. and Japanese
automobile manufacturers.
To protect your engine’s warranty use Motorcraft SAE 5W-20 or an
equivalent 5W-20 oil meeting Ford specification WSS-M2C930-A.SAE
5W-20 oil provides optimum fuel economy and durability
performance meeting all requirements for your vehicle’s engine.
Do not use supplemental engine oil additives, cleaners or other engine
treatments. They are unnecessary and could lead to engine damage that
is not covered by Ford warranty.
Change your engine oil and filter according to the appropriate schedule
listed inscheduled maintenance information.
Ford production and aftermarket (Motorcraft) oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, start-up
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.
