Roadside emergencies
177

²Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.
²Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
²Be particularly careful if you are taking ªAntabuseº or other forms of
disulfiram for the treatment of alcoholism. Breathing gasoline vapors,
or skin contact could cause an adverse reaction. In sensitive
individuals, serious personal injury or sickness may result. If fuel is
splashed on the skin, promptly wash skin thoroughly with soap and
water. Consult a physician immediately if you experience an adverse
reaction.
Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel is prohibited by law
and could damage your vehicle.
Do not use gasolines containing methanol. It can damage critical fuel
systems components.
Vehicles certified to meet California emission standards (indicated on the
underhood Vehicle Emissions Control Information label) are designed to
operate on California cleaner-burning, low-sulfur gasolines. If you have a
California-certified vehicle and California cleanerÐburning gasoline is not
available when you refuel, your engine should perform adequately.
However, the performance of the emission control devices and systems
may be adversely affected. In New York and Massachusetts, which have
adopted California's emission standards without requiring the sale of
California cleaner-burning gasoline, repairs to correct the effects of using
non-California fuel may not be covered by the emissions warranty.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based compounds containing (MMT).
Repairs to correct the effects of using a fuel for which your vehicle was
not designed may not be covered by your warranty.
Maintenance and care
214

Running out of fuel
Avoid running out fuel because this situation may have an adverse affect
on powertrain components.
If you have run out of fuel:
²You may need to crank the engine several times before the system
starts to pump fuel from the tank to the engine.
²Your ªCheck Engineº light may come on. For more information on the
ªCheck Engineº light, refer to theInstrumentationchapter.
Fuel Filler Cap
Your fuel tank filler cap has an indexed design with a one-eighth turn
on/off feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise 1/8 of a turn until it
stops.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the
filler pipe.
5. Turn the filler cap clockwise 1/8 of a turn until it stops.
If the ªService Engine Soon/Check Engine ª 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 a genuine
Ford or Motorcraft part. The customer warranty may be void for
any damage to the fuel tank or fuel system if a genuine Ford or
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.

3. Remove the bulb retaining ring by
rotating it counterclockwise (when
viewed from the rear) about 1/8
turn to free it from the bulb socket,
and slide the ring off the plastic
base. Keep the ring to retain the
new bulb.
4. Remove the old bulb from the lamp assembly by gently pulling it
straight back out of the lamp assembly.
To install the new bulb:
1. With the flat side of the new
bulb's plastic base facing upward,
insert the glass end of the bulb into
the lamp assembly. You may need to
turn the bulb left or right to align
the grooves in the plastic base with
the tabs in the lamp assembly. When
the grooves are aligned, push the bulb into the lamp assembly until the
plastic base contacts the rear of the lamp assembly.
2. Install the bulb retaining ring over the plastic base until it contacts the
rear of the socket by rotating clockwise until you feel a ªstop.º
3. Install the electrical connector into the rear of the plastic base until it
snaps, locking it into position.
4. Turn the headlamps on and make sure they work properly. If the
headlamp was correctly aligned before you changed the bulb, you should
not need to align it again.
Replacing front parking lamp/turn signal bulbs
1. Remove screw from the lamp
assembly.
2. Disengage lamp assembly.
