What you should do if the check
engine light illuminates
Light turns on solid:
This means that the OBD II system
has detected a malfunction.
Temporary malfunctions may cause
your
check engine light to
illuminate. Examples are:
¥ The vehicle has run out of fuel
(The engine may misfire or run
poorly.)
¥ Poor fuel quality or water in the
fuel
¥ The fuel cap may not have been
securely tightened. The
checkengine indicator light
illuminates when the ignition is
first turned to the ON position to
check the bulb. If it comes on
after the engine is started, one of
the engineÕs emission control
systems may be malfunctioning.
The light may illuminate without a
driveability concern being noted.
The vehicle will usually be drivable
and will not require towing.

12These temporary malfunctions can
be corrected by filling the fuel tank
with good quality fuel and/or
properly tightening the fuel cap.
After three drive cycles without
these or any other temporary
malfunctions present, the
check
engine
light should turn off. (A
driving cycle consists of a cold
engine startup followed by mixed
city/highway driving.)
No additional vehicle service is
required.If the Ò
check engineÓ
light remains on, have your vehicle
serviced at the first available
opportunity.
Light is blinking:
Engine misfire is occuring which
could damage your catalytic
converter. You should drive in a
moderate fashion (avoid heavy
acceleration and deceleration) and
have your vehicle serviced at the
first available opportunity.
Under engine misfire
conditions, excessive
exhaust temperatures could
damage the catalytic converter,
the fuel system, interior floor
coverings or other vehicle com-
ponents, possibly causing a fire.

IMPORTANT FUEL
INFORMATON
Important safety precautions
Do not overfill the fuel tank.
The pressure in an overfilled
tank may cause leakage and lead
to fuel spray and fire.
If you do not use the proper
fuel cap, the pressure in the
fuel tank can damage the fuel
system or cause it to work
improperly in a collision.
The fuel system may be
under pressure. If the fuel
cap is venting vapor or if you hear
a hissing sound, wait until it stops
before completely removing the
cap.
Automotive fuels can cause
serious injury or death if
misused or mishandled.

Maintenance and care

Observe the following guidelines
when handling automotive fuel:
¥ Extinguish all smoking materials
and any open flames before fueling
your vehicle.
¥ Always turn off the vehicle
before fueling.
¥ Make sure the fuel cap is
correctly fitted after fueling.
Failure to do so may cause the on
board diagnostic system to
illuminate the CHECK ENGINE
light.
¥ Automotive fuels can be harmful
or fatal if swallowed. If fuel is
swallowed, call a physician
immediately, even if no symptoms
are immediately apparent. The
toxic effects of fuel may not be
visible for hours.
¥ Fuels can also be harmful if
absorbed through the skin. If fuel is
splashed on the skin, promptly
remove contaminated clothing and
wash skin thoroughly with soap
and water.
¥ If fuel is splashed in the eyes,
remove contact lenses (if worn),
flush with water for 15 minutes and
seek medical attention.
¥ Be particularly careful if you are
taking ÒAntabuseÓ or other forms of
disulfiram for the treatment of
alcoholism. Breathing gasoline
vapors or skin contact could cause
an adverse reaction. Consult a
physician immediately.

Fuel filler cap
If the Òcheck engineÓ indicator
comes on and stays on when you
start the engine, the fuel filler cap
may not be properly installed. Turn
off the engine, remove the fuel
filler cap and reinstall it being
careful to align the cap properly.
If you must replace the fuel
filler cap, replace it with an
authorized Motorcraft part.
The customer warranty may be
void for any damage to the fuel
tank or fuel system if an
authorized Motorcraft fuel
filler cap is not used.
The fuel system may be
under pressure. If the fuel
filler cap is venting vapor or if you
hear a hissing sound, wait until it
stops before completely removing
the fuel filler cap. Otherwise fuel
may spray out and injure you or
others.
Cleaner air
Ford approves the use of gasolines
to improve air quality, including
reformulated gasolines that contain
oxygenates such as a maximum of
10% ethanol or 15% MTBE. There
should be no more than 5%
methanol with cosolvents and
additives to protect the fuel
system.
