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.

Maintenance and care
197
Watch for fluid leaks, strange
odors, smoke, loss of oil pressure,
engine overheating, illumination of
the
charging systemwarning light
or the
check enginewarning light.
These events could indicate that
the emission control system is not
working properly.
Exhaust leaks may result in
entry of harmful and
potentially lethal fumes into the
passenger compartment.

Alternative design
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.

Maintenance and care
198
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 under
the hood. This decal identifies
engine displacement and gives
some tune up specifications.
Please consult your ÒWarranty
GuideÒ for complete emission
warranty information.
Readiness for
inspection/maintenance (I/M)
testing
In some localities, it may be a legal
requirement to pass an I/M test of
the on-board diagnostic (OBD-II)
system. If your
check enginelight
is on, refer to the description in the
Instrument Cluster Lights and
Chimes
section of the
Instrumentation chapter. Your
vehicle may not pass the I/M test
with the
check engine light on.

Clean the instrument panel with a
damp cloth, then dry with a dry
cloth.
Any cleaner or polish that
increases the gloss of the upper
portion of the instrument panel
should be avoided. The dull finish
in this area is to help protect the
driver from undesirable windshield
reflection.
