Service Engine Soon
Theservice engine soonindicator light illuminates when the
ignition is first turned to the on position to check the bulb and
to indicate whether the vehicle is ready for
Inspection/Maintenance (I/M) testing. Normally, the “service engine soon”
light will stay on until the engine is cranked, then turn itself off if no
malfunctions are present. However, if after 15 seconds the “service
engine soon” light blinks eight times, it means that the vehicle is not
ready for I/M testing. See theReadiness for inspection/maintenance
(I/M) testingin theFuel and Refuelingchapter.
Solid illumination after the engine is started indicates the on-board
diagnostics system (OBD-II) has detected a malfunction. Refer to
On-board diagnostics (OBD-II)in theFuel and Refuelingchapter. If
the light is blinking, engine misfire is occurring which could damage your
catalytic converter. Drive in a moderate fashion (avoid heavy acceleration
and deceleration) and have your vehicle serviced immediately by your
authorized dealer.
WARNING:Under engine misfire conditions, excessive exhaust
temperatures could damage the catalytic converter, the fuel
system, interior floor coverings or other vehicle components, possibly
causing a fire.

disabled by the driver.

EMISSION CONTROL SYSTEM
WARNING:Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.
WARNING:Exhaust leaks may result in entry of harmful and
potentially lethal fumes into the passenger compartment. If you
smell exhaust fumes inside your vehicle, have your dealer inspect your
vehicle immediately. Do not drive if you smell exhaust fumes.
Your vehicle is equipped with various emission control components and a
catalytic converter which 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 inScheduled Maintenance Information
performed according to the specified schedule.
The scheduled maintenance items listed inScheduled Maintenance
Informationare essential to the life and performance of your vehicle
and to its emissions system.
If other than Ford, Motorcraft® or Ford-authorized parts are used for
maintenance replacements or for service of components affecting
emission control, such non-Ford parts should be 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.
