1997 Mercury Sable air condition

Driving while you tow
Do not drive faster than 72 km/h (45 mph) with any
weight on the trailer while towing on a hot day or in
hilly country.
Cruise control may shut off if you are towing on
long, steep grades.
When towing a trailer:
²Use 2 (Second) (if equipped) or 1 (First) when
towing up or down steep hills. This will eliminate
excessive downshifting and upshifting for
optimum fuel economy and transaxle cooling.
²Anticipate stops and brake gradually.
Servicing after towing
If you tow a trailer for long distances, your vehicle
will require more frequent service intervals. Refer to
theService Guidefor more information.
Trailer towing tips
²Practice turning, stopping and backing up in an
area before starting on a trip to get the feel of the
vehicle trailer combination. When turning, drive
slightly beyond the normal turning point so the
trailer wheels will clear curbs and other obstacles.
²Allow more room for stopping with a trailer
attached.
²The trailer tongue weight should be 10±15% of
the loaded trailer weight.
²After you have traveled 80 km (50 miles),
thoroughly check your hitch, electrical
connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in
hot weather, place the gearshift in P (Park) and
increase idle speed. This aids engine cooling and
air conditioner efficiency.
²Vehicles with trailers should not be parked on a
grade. If you must park on a grade, place wheel
chocks under the trailer's wheels.

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
fuel, see your dealer or a qualified service technician
to prevent any engine damage.
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:
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.

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.
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.

exterior accessories, such as antennas, before
entering a car wash.
²After washing, apply the brakes several times to
dry them.
Waxing your vehicle
The best way to determine when the paintwork
needs waxing is by noting when water stops beading
on the surface. This could be every three or four
months, depending on operating conditions.
Use only carnauba or synthetic-based waxes.
Remove any bugs and tar before waxing vehicle. Use
cleaning fluid or alcohol with a clean cloth to
remove. Use tar remover to remove any tar spots.
Repairing paint chips
Minor scratches or paint damage from road debris
may be repaired with touch-up paint, paint repair
foil or aerosol paint spray from the Ford accessory
line. Observe the application instructions on the
products.
Remove particles such as bird droppings, tree sap,
insect remains, tar spots, road salt and industrial
fallout immediately.
Cleaning the wheels
Wash the wheels with
the same detergent you
use to clean the body
of your vehicle. Do not
use acid-based wheel cleaners, steel wool, fuel or
strong detergents. Never use abrasives that will
damage the finish of special wheel surfaces. Use a
tar remover to remove grease and tar.
Cleaning the engine
Engines are more efficient when they are clean
because grease and dirt buildup act as insulators and
keep the engine warmer than normal. Follow these
guidelines to clean your engine:
