Your vehicle is equipped with various
emission control components and a catalytic
converter that will enable your vehicle to
comply with applicable exhaust emission
standards. To make sure that the catalytic
converter and other emission control
components continue to work properly:
Use only the specified fuel listed.
Avoid running out of fuel.
Do not turn off the ignition while your
vehicle is moving, especially at high
speeds.
Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
The scheduled maintenance items listed in
scheduled maintenance information are
essential to the life and performance of your
vehicle and to its emissions system.
If you use parts other than Ford, Motorcraft
or Ford-authorized parts for maintenance
replacements, or for service of components
affecting emission control, such non-Ford
parts should be the equivalent to genuine
Ford Motor Company parts in performance
and durability.
Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.
An improperly operating or damaged exhaust
system may allow exhaust to enter the
vehicle. Have a damaged or improperly
operating exhaust system inspected and
repaired immediately.
Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles are
not permitted to intentionally remove an
emission control device or prevent it from
working. Information about your vehicle’s
emission system is on the Vehicle Emission
Control Information Decal located on or near
the engine. This decal also lists engine
displacement
Please consult your warranty information for
complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as the
on-board diagnostics system (OBD-II) that
monitors the engine’s emission control
system. The system protects the environment
by making sure that your vehicle continues
to meet government emission standards. The
OBD-II system also assists a service
technician in properly servicing your vehicle.
When the service engine soon
indicator illuminates, the OBD-II
system has detected a malfunction.
Temporary malfunctions may cause the
service engine soon indicator to illuminate.
Examples of temporary malfunctions are:
the vehicle has run out of fuel—the
engine may misfire or run poorly
poor fuel quality or water in the fuel—the
engine may misfire or run poorly
the fuel fill inlet may not have closed
properly. See Refueling (page 169).
driving through deep water—the
electrical system may be wet.
