Ford 1996 Windstar Manual page 361

Servicing Your Windstar
Ford strongly recommends the use of genuine Ford replacement
parts. If other than Ford or Motorcraft parts or Ford authorized
remanufactured parts are used for maintenance replacements or
for the service of components affecting emission control, such
non-Ford parts should be equivalent to genuine Ford Motor
Company parts in performance and durability. It is the owner's
responsibility to determine the equivalency of such parts. Please
consult your warranty booklet for complete warranty
information.
Never use a metal exhaust collector when you service your
vehicle. If the metal collector contacts any of your vehicle's
plastic trim or bumper parts they could melt or deform.
Do not drive your vehicle if it does not operate properly. See
your dealer if the engine runs on for more than five seconds
after you shut it off or if it misfires, surges, stalls, or backfires.
Information about your vehicle's emissions control system is on
the Vehicle Emission Control Information decal located on or
near the engine. This decal identifies engine displacement and
gives some tune-up specifications.
Readiness for Inspection/Maintenance Testing
In some localities it may become a legal requirement to pass an
Inspection/Maintenance (I/M) test of the On-Board Diagnostic
(OBD) II system. If the vehicle's powertrain system or its battery
has just been serviced, the OBD II system is reset to a not ready
for I/M testing condition. To prepare for I/M testing, the law
specifies a "need for additional mixed city and highway driving
to complete the check" of the OBD II system. As soon as all of
the OBD II system checks are successfully completed, the OBD
II system is set to the ready condition. The amount of driving
required to reach the ready condition varies with individual
driving patterns. To complete this requirement in the minimum
amount of time, refer to the OBD II Drive Cycle defined below.
If the vehicle owner cannot or does not want to do the
additional driving required by law, a service center can perform
this drive cycle as it would any other type of repair work.
