Scheduled Maintenance
Axle and Transfer Case Maintenance
Axle(s) and transfer case, four-wheel drive
vehicles, fluid changes or level checks are
not required unless a leak is suspected or
the assembly has been submerged in
water. Contact an authorized dealer for
service.
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 oil
that meets our specification or has an
American Petroleum Institute (API)
Certified for Gasoline Engines (Certification
mark) oil, the normal oil change interval is
3,000 mi (4,800 km).
Engine Air Filter Replacement
The life of the engine 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.
