1997 FORD TAURUS Owners Manual

Tires that are larger or smaller than your vehicle's
original tires may also affect the accuracy of your
speedometer.
SNOW TIRES AND CHAINS
The tires on your vehicle have all weather treads to
provide traction in rain and snow. However, in some
climates, you may need to use snow tires and
chains. Follow these guidelines when using snow
tires and chains:
²Use only SAE Class S chains.
²Install chains securely, verifying that the chains do
not touch any wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the chains rub or
bang against your vehicle, stop and re-tighten the
chains. If this does not work, remove the chains
to prevent damage to your vehicle.
²If possible, avoid fully loading your vehicle.
²Do not use tire chains on aluminum wheels.
²Do not use tire chains if your vehicle is equipped
with P225/55VR16 tires.
²Remove the tire chains when they are no longer
needed. Do not use tire chains on dry roads.
²The suspension insulation and bumpers will help
prevent vehicle damage. Do not remove these
components from your vehicle when using snow
tires and chains.
WHAT YOU SHOULD KNOW ABOUT
AUTOMOTIVE FUELS
Important safety precautions
Do not overfill the fuel tank. The pressure in
an overfilled tank may cause leakage and
lead to fuel spray and fire.
Maintenance and care

ProCarManuals.com

If you do not use the proper fuel cap, the
pressure in the fuel tank can damage the
fuel system or cause it to work improperly in a
collision.
The fuel system may be under pressure. If
the fuel cap is venting vapor or if you hear a
hissing sound, wait until it stops before completely
removing the cap.
Automotive fuels can cause serious injury or
death if misused or mishandled.
Observe the following guidelines when handling
automotive fuel:
²Extinguish all
smoking materials
and any open flames
before fueling your
vehicle.
²Always turn off the
vehicle before
fueling.
²Automotive fuels can be harmful or fatal if
swallowed. If fuel is swallowed, call a physician
immediately, even if no symptoms are immediately
apparent. The toxic affects of fuel may not be
visible for hours.
²Fuels can also be harmful if absorbed through the
skin. If fuel is splashed on the skin, promptly
remove contaminated clothing and wash skin
thoroughly with soap and water.
²If fuel is splashed in the eyes, remove contact
lenses, flush with water for 15 minutes and seek
medical attention.
Maintenance and care

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.
Consult a physician immediately.
Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel
is prohibited by law and could damage your vehicle.
The damage may not be covered by your warranty.
Your vehicle was not designed to use fuel containing
manganese-based additives such as MMT.
Additionally, vehicles certified to California emission
standards (indicated on the underhood Vehicle
Emissions Control Information label) are designed to
operate on California reformulated gasolines. If
California reformulated gasoline is not available
when you refuel, your vehicle can be operated on
non-California fuels. However, even though your
engine will perform adequately on other gasolines,
the performance of the emission control devices and
systems may be adversely affected. Repair of
damage caused by using a fuel that your vehicle was
not designed for may not be covered by your
warranty.
Octane recommendations
Your vehicle is
designed to use regular
gasoline with an
(R+M)/2 octane rating
of 87. We do not
recommend gasolines
labeled as ªregularº in
high altitude areas that
are sold with octane
ratings of 86 or even less.
Do not be concerned if your vehicle sometimes
knocks lightly. However, if it knocks heavily under
most driving conditions on the recommended octane
87
Maintenance and care

fuel, see your dealer or a qualified service technician
to prevent any engine damage.
SHO engines
Your vehicle is
designed to use
premium gasoline for
optimum performance
with an (R + M)/2 octane rating of 91 or higher.
Gasolines with lower octane ratings can be used but
performance may decrease. We do not recommend
gasolines labeled as ªpremiumº in high altitude areas
that are sold with octane ratings less than 91.
Fuel quality
If you are experiencing starting, rough idle or
hesitation problems try a different brand of fuel. If
the condition persists, see your dealer or a qualified
service technician.
The American Automobile Manufacturers Association
(AAMA) issued a gasoline specification to provide
information on high quality fuels that optimize the
performance of your vehicle. We recommend the use
of gasolines that meet the AAMA specification if
they are available.
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 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.
Calculating fuel economy
To accurately calculate your vehicle's fuel economy:
91
Maintenance and care
141

1. Fill the tank completely and record the initial
odometer reading.
2. Each time you fill the tank, record the amount of
fuel added (in liters or gallons).
3. After at least three to five fuel tank fill-ups, fill
the fuel tank and record the current mileage
reading.
4. Use one of the following equations to calculate
fuel economy.
Liters used x 1004Total kilometers traveled
Total miles traveled4Total gallons used
Keep a record for at least one month. This will
provide an accurate estimate of the vehicle's fuel
economy.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with catalytic converters
which enable your vehicle to comply with applicable
exhaust emission requirements.
Exhaust leaks may result in the entry of
harmful and potentially lethal fumes into the
passenger compartment. Under extreme conditions
excessive exhaust temperatures could damage the
fuel system, the interior floor covering, or other
vehicle components, possibly causing a fire.
To make sure that the catalytic converter and the
other emission control parts continue to work
properly:
²Use only unleaded fuel.
²Avoid running out of fuel.
²Do not turn off the ignition while your vehicle is
moving, especially at high speeds.
²Have the services listed in yourService Guide
performed according to the specified schedule.
Maintenance and care
142
ProCarManuals.com

The Scheduled Maintenance Services listed in the
Service Guideare required because they are
considered essential to the life and performance of
your vehicle and to its emissions system.
Ford strongly recommends the use of genuine Ford
replacement parts. If other than Ford or Motorcraft
parts or Ford authorized parts are used for
maintenance replacements or for the service of
components affecting emission control, such
non-Ford parts should be equivalent to genuine Ford
Motor Company parts in performance and durability.
It is the owner's responsibility to determine the
equivalency of such parts. Please consult your
Warranty Information Booklet for complete warranty
information.
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.
Watch for fluid leaks, strange odors, smoke, loss of
oil pressure, the charging system warning light, the
service engine soon light or the temperature warning
light. These sometimes indicate that the emissions
system is not working properly.
Do not make any unauthorized changes to your
vehicle or engine. Changes that cause more
unburned fuel to reach the exhaust system can
increase the temperature of the engine or exhaust
system.
By law, anyone who manufactures, repairs, services,
sells, leases, trades vehicles, or supervises a fleet of
vehicles is not permitted to intentionally remove an
emission control device or prevent it from working.
In some of the United States and Canada, vehicle
owners may be liable if their emission control device
is removed or prevented from working.
Maintenance and care
143
ProCarManuals.com

Never use a metal exhaust collector when you
service your vehicle. If the metal collector contacts
any of your vehicle's plastic trim or bumper parts
they could melt or deform.
Do not drive your vehicle if it does not operate
properly. See your dealer if the engine runs on for
more than five seconds after you shut it off or if it
misfires, surged, stalls or backfires.
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.
Readiness for inspection/maintenance testing
In some localities, it may become a legal
requirement to pass an Inspection/Maintenance (I/M)
test of the On-board Diagnostic (OBD) II system. If
the vehicle's powertrain system or its battery has
just been serviced, the OBD II system is reset to a
not ready for I/M testing condition. To prepare for
I/M testing, the law specifies that additional mixed
city and highway driving is required to complete the
check of the OBD II system.
The driving modes required to reach the ready
condition consist of a minimum of 30 minutes of city
and highway driving as described below:
²At least twenty minutes driving in stop and go,
city type traffic with at least four idle periods.
²At least ten minutes of driving on an expressway
or highway.
Before completing the above driving modes, the
engine must be warmed up and at operating
temperature. Once started, the vehicle must not be
turned off during these driving modes.
EXTERIOR LAMPS
It is a good idea to check the operation of the
following lights frequently:
