2001 FORD MUSTANG Owners Manual

Many of the world's
automakers issued the
World-wide Fuel
Charter that
recommends gasoline
specifications to
provide improved
performance and
emission control
system protection for your vehicle. Gasolines that
meet the World-wide Fuel Charter should be used
when available. Ask your fuel supplier about
gasolines that meet the World-wide Fuel Charter. In
Canada, look for fuels that display theAuto
Makers' Choiceylogo.
Cleaner air
Ford endorses the use of reformulated
ªcleaner-burningº gasolines to improve air quality.
Running out of fuel
Avoid running out of fuel because this situation may
have an adverse affect on powertrain components.
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 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.
Maintenance and care
185

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 capacitiessection ofthe
Capacities 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 fuel remaining in the fuel tank after the fuel
gauge indicates empty.
The amount of usable fuel in the 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
186

For consistent results when filling the fuel tank:
²Turn the engine/ignition switch to the off position
prior to refueling, an error in the reading will
result if the engine is left running.
²Use the same filling rate setting (low Ð medium
Ð high) each time the tank is filled.
²Allow no more than 2 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.
Maintenance and care
187

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.
Habits
²Smooth, moderate operation can yield up to 10%
savings in fuel.
²Steady speeds without stopping will usually give
the best fuel economy.
²Idling for long periods of time (greater than one
minute) may waste fuel.
²Anticipate stopping; slowing down may eliminate
the need to stop.
²Sudden or hard accelerations may reduce fuel
economy.
²Slow down gradually.
²Driving at reasonable speeds (traveling at 88 km/h
[55 mph] uses 15% less fuel than traveling at 105
km/h [65 mph]).
²Revving the engine before turning it off may
reduce fuel economy.
²Using the air conditioner or defroster may reduce
fuel economy.
²You may want to turn off the speed control in
hilly terrain if unnecessary shifting between third
and fourth gear occurs. Unnecessary shifting of
this type could result in reduced fuel economy.
Maintenance and care
188

²Warming up a vehicle on cold mornings is not
required and may reduce fuel economy.
²Resting your foot on the brake pedal while driving
may reduce fuel economy.
²Combine errands and minimize stop-and-go
driving.
Maintenance
²Keep tires properly inflated and use only
recommended size.
²Operating a vehicle with the wheels out of
alignment will reduce fuel economy.
²Use recommended engine oil. Refer toLubricant
specifications.
²Perform all regularly scheduled maintenance
items. Follow the recommended maintenance
schedule and owner maintenance checks found in
your vehicle scheduled maintenance guide.
Conditions
²Heavily loading a vehicle or towing a trailer may
reduce fuel economy at any speed.
²Carrying unnecessary weight may reduce fuel
economy (approximately 0.4 km/L [1 mpg] is lost
for every 180 kg [400 lb] of weight carried).
²Adding certain accessories to your vehicle (for
example bug deflectors, rollbars/light bars,
running boards, ski/luggage racks) may reduce
fuel economy.
²Using fuel blended with alcohol may lower fuel
economy.
²Fuel economy may decrease with lower
temperatures during the first 12±16 km (8±10
miles) of driving.
²Driving on flat terrain offers improved fuel
economy as compared to driving on hilly terrain.
²Transmissions give their best fuel economy when
operated in the top cruise gear and with steady
pressure on the gas pedal.
²Close windows for high speed driving.
Maintenance and care
189

EPA window sticker
Every new vehicle should have the EPA window
sticker. Contact your dealer if the window sticker is
not supplied with your vehicle. The EPA window
sticker should be your guide for the fuel economy
comparisons with other vehicles.
It is important to note the box in the lower left
corner of the window sticker. These numbers
represent the Range of L/100 km (MPG) expected
on the vehicle under optimum conditions. Your fuel
economy may vary depending upon the method of
operation and conditions.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission
control components and a catalytic converter which
will enable your vehicle to comply with applicable
exhaust emission standards. To make sure that the
catalytic converter and other emission control
components continue to work properly:
²Use only the specified fuel listed.
²Avoid running out of fuel.
²Do not turn off the ignition while your vehicle is
moving, especially at high speeds.
²Have the items listed in your scheduled
maintenance guide performed according to the
specified schedule.
The scheduled maintenance items listed in the
scheduled maintenance guide are essential to the life
and performance of your vehicle and to its emissions
system.
If other than Ford, Motorcraft or Ford-authorized
parts are used for maintenance replacements or for
service of components affecting emission control,
such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and
durability.
Maintenance and care
190

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.
Illumination of the ªService Engine Soonº light,
charging system warning light or the temperature
warning light, fluid leaks, strange odors, smoke or
loss of engine power, 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.
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 on or near the engine. This decal identifies
engine displacement and gives some tune up
specifications.
Please consult yourWarranty Guidefor 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 diagnostics system.
If your ªCheck Engine/Service Engine Soonº light is
on, refer to the description in theWarning lights
and chimessection of theInstrumentation
chapter. Your vehicle may not pass the I/M test with
the ªCheck Engine/Service Engine Soonº light on.
Maintenance and care
191

If the vehicle's powertrain system or its battery has
just been serviced, the on-board diagnostics system
is reset to a ªnot ready for I/M testº condition. To
ready the on-board diagnostics system for I/M
testing, a minimum of 30 minutes of city and
highway driving is necessary as described below:
²First, at least 10 minutes of driving on an
expressway or highway.
²Next, at least 20 minutes driving in stop-and-go,
city-type traffic with at least four idle periods.
Allow the vehicle to sit for at least eight hours
without starting the engine. Then, start the engine
and complete the above driving cycle. The engine
must warm up to its normal operating temperature.
Once started, do not turn off the engine until the
above driving cycle is complete.
BULBS
Replacing exterior bulbs
Check the operation of the following lamps
frequently:
²Headlamps
²Tail lamps
²Brakelamps
²High-mount brakelamp
²Turn signals
²Backup lamps
²License plate lamp
Do not remove lamp bulbs unless they will be
replaced immediately. If a bulb is removed for an
extended period of time, contaminants may enter
the lamp housings and affect performance.
