(96,000 kilometers). In addition, follow
this 60,000 mile (96,000 kilometer)
schedule when operating your vehicle

California Fuel Filter Replacement

If you register your vehicle in California, the
California Air Resources Board has
determined that the failure to perform this
maintenance item does not nullify the
emission warranty or limit recall liability
before the completion of your vehicle's
useful life. Ford Motor Company, however,
urges you to have all recommended
maintenance services performed at the
specified intervals and to record all vehicle
service.

Hot Climate Oil Change Intervals

Vehicles operating in the Middle East,
North Africa, Sub-Saharan Africa or
locations with similar climates using an
American Petroleum Institute (API)
Certified for Gasoline Engines (Certification
mark) oil of SM or SN quality, the normal
oil change interval is 3000 miles (5000
kilometers).

If the available API SM or SN oils are not
available, then the oil change interval is
1800 miles (3000 kilometers).

Engine Air Filter and Cabin Air Filter
Replacement

The life of the engine air filter and cabin air
filter is dependent on exposure to dusty
and dirty conditions. Vehicles operated in
these conditions require frequent
inspection and replacement of the engine
air filter and cabin air filter.

Diesel Particulate Filter

The filter may need to be removed for ash
cleaning at approximately 120000 miles
(192000 kilometers) or greater (actual
mileage can vary greatly depending upon
engine and vehicle operating conditions)
and replaced with a new or
remanufactured (ash cleaned) part. The
filter may need to be replaced at
approximately 250000 miles (400000
kilometers) depending upon engine and
vehicle operating conditions. In both cases,
the engine control system sets a service
light (wrench icon) to inform you to bring
your vehicle to the dealer for service. If
there are any issues with the oxidation
catalyst or particulate filter system, a
service light (wrench or engine icon) sets
by the engine control system to inform you
to bring your vehicle into a dealer for
service.
