Introduction

Remember to turn the ignition OFF when refueling your vehicle.
Otherwise, the display will not show the addition of fuel for a few miles.
At least four gallons of fuel must be added for the fuel gauge to
immediately show the new fuel level.
The DTE function will flash for 5 seconds and sound a tone for 1 second
when you have approximately:
²80 km (50 miles) left before you run out of fuel
²40 km (25 miles)
²16 km (10 miles)
The message center will remain in
the DTE function until the SELECT
control is pressed to change
functions.
Displayed DTE will not be equal to
AVG ECON multiplied by the FUEL
REMAIN value. DTE is calculated
using a method that considers the
fuel economy of the last 800 km
(500 miles) driven.
If ªCOº or ªCSº is displayed, there is a problem with the fuel indication
system and you should contact your dealer for service as soon as
possible.
AVG FUEL ECONOMY (average fuel economy)
Select this function to display your
average fuel economy in liters/100
km or miles/gallon.
If you calculate your average fuel
economy by dividing miles traveled by gallons used, your figure may be
different than displayed for the following reasons:
²your vehicle was not perfectly level during fill-up
²differences in the automatic shut-off points on the fuel pumps at
service stations
²variations in top-off procedure from one fill-up to another
²rounding of the displayed values to the nearest 0.1 liter (gallons)

Roadside coverage beyond basic warranty
In the United States, you may purchase additional roadside assistance
coverage beyond this period through the Ford Auto Club by contacting
your Ford or Lincoln Mercury dealer.
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
The fuel pump shut-off switch is a device intended to stop the electric
fuel pump when your vehicle has been involved in a substantial jolt.
After a collision, if the engine cranks but does not start, the fuel pump
shut-off switch may have been activated.
Roadside emergencies
134

The fuel pump shut-off switch is
located on the left side of the trunk
behind the trunk liner.
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.

Roadside emergencies

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.
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.
Maintenance and care
177

If you have run out of fuel:
²You may need to cycle the ignition from OFF to ON several times after
refueling, to allow the fuel system to pump the fuel from the tank to
the engine.
²Your ªCheck Engineº indicator may come on. For more information on
the ªCheck Engineº indicator, refer to theInstrumentationchapter.
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.
ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fillups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1 600 km (1 000
miles) of driving (engine break-in period). You will get a more accurate
measurement after 3 000 km±5 000 km (2 000 miles-3 000 miles).
Filling the tank
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in theRefill Capacities
section of theCapacities and specificationschapter.
The advertised capacity is the amount of the indicated capacity and the
empty reserve combined. Indicated capacity is the difference in the
amount of fuel in a full tank and a tank when the fuel gauge indicates
empty. Empty reserve is the small amount of usable fuel remaining in the
fuel tank after the fuel gauge indicates empty.
The amount of empty reserve varies and should not be relied
upon to increase driving range. When refueling your vehicle after
the fuel gauge indicates empty, you might not be able to refuel
the full amount of the advertised capacity of the fuel tank due to
the empty reserve still present in the tank.
Maintenance and care
180

For consistent results when filling the fuel tank:
²Use the same filling rate setting (low Ð medium Ð high) each time
the tank is filled.
²Allow three automatic click-offs when filling.
²Always use fuel with the recommended octane rating.
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.
Driving style Ð good driving and fuel economy habits
Give consideration to the lists that follow and you may be able to change
a number of variables and improve your fuel economy.
