Exceptions
There are several exceptions to the Normal
Schedule:
Axle and PTU maintenance
: The Power
Transfer Unit (PTU) and rear axle (AWD
only) in your vehicle does not require any
normal scheduled maintenance. The PTU
lubricant will be more likely to require a
fluid change if the vehicle has extended
periods of extreme or severe duty cycle
driving. Changing or checking the PTU
lubricant is not necessary unless the unit
has been submerged in water or shows
signs of leakage. Contact your 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
American Petroleum Institute (API)
Certified for Gasoline Engines (Certification
mark) oil of SM or SN quality, the normal
oil change interval is 5,000 mi (8,000 km)
