HAZARD FLASHER
Use only in an emergency to warn traffic of vehicle
breakdown, approaching danger, etc. The hazard
flashers can be operated when the ignition is off.
²The hazard lights
control is located on
top of the steering
column.
²Depress hazard
lights control to
activate all hazard
flashers
simultaneously.
²Depress control again to turn the flashers off.
RESETTING THE FUEL PUMP SHUT-OFF
SWITCH
After a collision, if the engine cranks but does not
start, the fuel pump shut-off switch may have been
activated. The shut-off switch is a device intended to
stop the electric fuel pump when your vehicle has
been involved in a substantial jolt.
The fuel pump shut-off
switch is located on
the left side of the
trunk behind the trunk
liner.
Roadside emergencies
112

Use the following procedure to reset the fuel pump
shut-off switch.
1. Turn the ignition to the OFF position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, reset the fuel pump
shut-off switch by pushing in on the reset button.
4. Turn the ignition to the ON position. Pause for a
few seconds and return the key to the OFF position.
5. Make a further check for leaks in the fuel system.
FUSES AND RELAYS
Fuses
If electrical
components in the
vehicle are not
working, a fuse may
have blown. Blown
fuses are identified by a broken wire within the fuse.
Check the appropriate fuses before replacing any
electrical components.
Always replace a fuse with one that has the
specified amperage rating. Using a fuse with
a higher amperage rating can cause severe wire
damage and could start a fire.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the
brake heavily. Instead, gradually decrease your
speed. Hold the steering wheel firmly and slowly
move to a safe place on the side of the road.
Roadside emergencies
119

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.
When refueling always shut the engine off
and never allow sparks or open flames near
the filler neck. Never smoke while refueling. Fuel
vapor is extremely hazardous under certain
conditions. Care should be taken to avoid inhaling
excess fumes.
The flow of fuel through a fuel pump nozzle
can produce static electricity, which can
cause a fire if fuel is pumped into an ungrounded
fuel container.
Use the following guidelines to avoid static build-up
when filling an ungrounded fuel container:
²Place approved fuel container on the ground.
²DO NOT fill a fuel container while it is in the
vehicle.
Maintenance and care
160

²Keep the fuel pump nozzle in contact with the
fuel container while filling.
²DO NOT use a device that would hold the fuel
pump handle in the fill position.
Fuel Filler Cap
Your fuel tank filler cap has an indexed design with
a 1/8 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 Engineº 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, align
the cap properly and reinstall it.
If you must replace the fuel filler cap, replace
it with a fuel filler cap that is designed for
your vehicle. The customer warranty may be
void for any damage to the fuel tank or fuel
system if the correct 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.
Maintenance and care
161

ªPremiumº unleaded gasoline is not recommended
(particularly in the United States) because it may
cause these problems to become more pronounced.
If the problems persist, see your dealer or a qualified
service technician.
It should not be necessary to add any aftermarket
products to your fuel tank if you continue to use a
high quality fuel.
Cleaner air
Ford approves the use of gasolines to improve air
quality, including reformulated gasolines that contain
oxygenates up to 10% ethanol or 15% MTBE.
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
after refueling before the system starts to pump
the fuel from the tank to the engine.
²Your ªService Engine Soonº indicator may come
on. For more information on the ªService Engine
Soonº indicator, refer to theInstrumentation
chapter.
Fuel Filter
For fuel filter replacement, see your dealer or a
qualified service technician. Refer to the Scheduled
Maintenance Guide for the appropriate intervals for
changing the fuel filter.
Replace the fuel filter with an authorized
Motorcraft part. The customer warranty may
be void for any damage to the fuel system if an
authorized Motorcraft fuel filter is not used.
Maintenance and care
163

²Use a known quality gasoline, preferably a
national brand.
²Use the same side of the same pump and have
the vehicle facing the same direction each time
you fill up.
²Have the vehicle loading and distribution the
same every time.
Your results will be most accurate if your filling
method is consistent.
Calculating fuel economy
1. Fill the fuel tank completely and record the initial
odometer reading (in kilometers or miles).
2. Each time you fill the tank, record the amount of
fuel added (in liters or gallons).
3. After at least three to five tank fill-ups, fill the
fuel tank and record the current odometer reading.
4. Subtract your initial odometer reading from the
current odometer reading.
5. Follow one of the simple calculations in order to
determine fuel economy:
Multiply liters used by 100, then divide by total
kilometers traveled.
Divide total miles traveled by total gallons
used.
Keep a record for at least one month and record the
type of driving (city or highway). This will provide
an accurate estimate of the vehicle's fuel economy
under current driving conditions. Additionally,
keeping records during summer and winter will show
how temperature impacts fuel economy. In general,
lower temperatures give lower fuel economy.
