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. Taurus
SHO vehicles are electronically monitored
and notify the driver required by service by
displaying a message in the information
display. 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,
shows sign of leakage or (Taurus SHO
only) 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.

filter and cabin air filter is dependent on
