1998 Mercury Villager maintenance

WARNING
Failure to follow these precautions may adversely affect
the handling of the vehicle and make it easier to lose control
and roll over.
Tires that are larger or smaller than your vehicle's original tires
may affect the accuracy of your speedometer and odometer.
Wheel and Tire Matching
See an authorized tire dealer for proper servicing procedures.
Wheels and tires must be properly removed, matched and
remounted to maintain the best possible ride.
Information About Tire Quality Grades
New vehicles are fitted with tires that have their Tire Quality
Grade (described below) molded into the tire's sidewall. These Tire
Quality Grades are determined by standards that the United
States Department of Transportation has set.
Tire Quality Grades apply to new pneumatic tires for use on this
vehicle. They do not apply to deep tread, winter-type snow
tires, space-saver or temporary use spare tires, tires with nominal
rim diameters of 10 to 12 inches (254-305 mm) or limited
production tires as defined in Title 49 Code of Federal Regulations
Part 575.104(c)(2).
U.S. Department of Transportation Ð Tire quality grades:The
U.S. Department of Transportation requires Ford to give you the
following information about tire grades exactly as the
government has written it.
Treadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a
specified government test course. For example, a tire graded

WARNING
The temperature grade for this tire is established for a tire
that is properly inflated and not overloaded. Excessive
speed, underinflation, or excessive loading, either
separately or in combination, can cause heat buidlup and
possible tire failure.
The information on braking performance and tire quality grading
found in the ªFord Motor Company Passenger Car Consumer
Informationº pamphlet (FPS 12024-92) also applies to the Villager.
This publication is available from your dealer.
Snow Tires and Cables
The tires on your vehicle have all-weather treads that provide
traction in rain or snow. However, during the winter months in
some climates, you may need to use snow tires and
occasionally cables for your tires.
WARNING
When using snow tires, make sure they are the same size
and grade as the tires you normally use on your
vehicle.
Do not use cables when using a temporary spare. For full size
tires, use cables on the tires only in an emergency or if the law
requires them where you drive. When you use the tire cables:
mMake sure the cables are the right size for your tires. Use only
SAE Class ªSº cables. Other types may damage your vehicle.
mPut cables on tightly with the ends held down securely. Follow
the cable manufacturer's instructions.

If you lose the fuel filler cap, replace it with an authorized
Motorcraft or equivalent part.
WARNING
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.
WARNING
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.
NOTE: If you replace your fuel filler cap with an aftermarket
fuel filler cap, the customer warranty may be void for
any damage to the fuel tank and/or fuel system.
A venting fuel tank is not an abnormal condition. It may be
caused by:
mtoo volatile a fuel for the weather conditions. Service stations
sometimes sell winter grade fuel in the summer.
mpulling a heavy load on hot days, or at high altitudes.
mextended periods of idling with the engine RPM increased
above the normal idle range.
mparking the vehicle in full sunlight for extended periods on
extremely hot days.
WARNING
Do not overfill the fuel tank. The pressure in an
overfilled tank may cause leakage and lead to fuel spray
and fire.

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 recommendation
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.

with a gasoline-methanol blend may cause the same kind of
adverse reaction as drinking an alcoholic beverage. In sensitive
individuals, serious personal injury or sickness could result.
Consult a physician promptly if you experience an adverse
reaction.
Running Out of Fuel
NOTE: Avoid running out of fuel because this situation may
have an adverse effect on modern powertrain
components.
You may need to crank the engine several times before the fuel
system starts to pump fuel from the tank to the engine.
Fuel Economy
Fuel economy is an estimate of the efficiency of your vehicle, and
can be calculated as Miles Per Gallon (MPG) or Liters Per 100
Kilometers (L/100K).
Do not calculate fuel economy during your vehicle's break-in
period. This would not be an accurate estimate of how much fuel
your vehicle will normally use.
To calculate fuel economy:
1. Fill the fuel tank completely and record the initial odometer
reading.
2. Every time you buy fuel, record the amount (in gallons or
liters) purchased.
3. After at least 3-5 tankfulls, fill the fuel tank and record the
final odometer reading.
4. Use these equations to calculate your fuel economy:
mEnglish: MPG = (total miles driven)4(gallons used)
Maintenance and Care

mMetric: L/100k = Multiply the number of liters used by 100
and divide the answer by the number of kilometers
travelled.
Comparisons With Environmental Protection Agency
(EPA) Fuel Economy Estimates
EPA fuel economy figures are obtained from laboratory tests
under simulated road conditions and may not reflect the actual
conditions you experience or your style of driving. The EPA fuel
economy estimate is not a guarantee that you will achieve the
fuel economy shown.
The following decrease fuel economy:
mLack of regular, scheduled maintenance
mRapid acceleration and excessive speed
mDriving with your foot on the brake
mSudden stops
mExtended engine idling
mUsing speed control in hilly terrain
mExtended use of the A/C, defroster, rear window defroster
and other accessories
mUnderinflated tires
mHeavy loads
mAftermarket add-ons such as bike, ski or luggage racks, bug
deflectors, etc.

Emission Control System
Your vehicle is equipped with a catalytic converter which enables
your vehicle to comply with applicable exhaust emission
requirements.
WARNING
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.
Malfunctions in the engine or exhaust system can result in
excessive exhaust system temperatures. Under extreme conditions
(for example, towing a trailer up a steep hill on a very hot day
with a malfunctioning engine or exhaust system), high exhaust
system temperatures could be damaging.
To make sure that the catalytic converter and the other emission
control parts continue to work properly:
mUse only unleaded fuel.
mAvoid running out of fuel.
mNever turn off the ignition while your vehicle is moving,
especially at high speeds.
mHave the services listed in yourMaintenance Schedulebooklet
performed according to the specified schedule.
Maintenance and Care

WARNING
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.
WARNING
Do not remove the floor carpet in your vehicle. Emission
controls cause high exhaust temperatures under the
floor.
Watch for fluid leaks, strange odors, smoke and loss of oil
pressure. Also watch for the charge warning light, the check engine
light, or the temperature warning light. These sometimes
indicate that the emission 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.
In general, maintenance, replacement, or service of the emission
control devices or systems in your new Ford Motor
Company vehicle or engine may be performed at your expense
by any automotive repair establishment or individual using
automotive parts equivalent to those with which your vehicle or
engine was originally equipped.
By law, anyone who manufactures, repairs, services, sells, leases
vehicles, 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
in Canada, vehicle owners may be liable if their emission control
device is removed or is prevented from working.
