Exceptions
There are several exceptions to the Normal
Schedule: 376
Flex (), enUSA, First Printing Scheduled Maintenance

Axle and PTU maintenance: The Power
Transfer Unit (PTU) and rear axle (AWD
only) in your vehicle does not require any
normal scheduled maintenance. Vehicles
are electronically monitored and notify the
driver required service by displaying a
message in the information display. The
PTU lubricant will be more likely to require
a change if the vehicle has experienced
extended periods of extreme/severe duty
cycle driving. Changing or checking the PTU
lubricant is not necessary unless the unit
has been submerged in water, shows signs
of leakage or a message indicating required
service is displayed. 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 5000 miles (8000
kilometers).
If the available API SM or SN oils are not
available, then the oil change interval is
3,000 mi (4,800 km)
.
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.
