1999 Mercury Villager fuel cap

Turn signal
Illuminates when the left or right
turn signal or the hazard lights are
turned on. If one or both of the
indicators stay on continuously or
flash faster, check for a burned-out
turn signal bulb. Refer toExterior bulbsin theMaintenance and care
chapter.
Speed control
This light comes on when either the
COAST/SET or RES/ACCEL controls
are pressed. It turns off when the
cruise cancel control is pressed, the brake is applied or the ignition is
turned to the OFF position.
Low fuel
Illuminates as an early reminder of a
low fuel condition indicated on the
fuel gauge (refer toFuel Gaugein
this chapter for more information).
When refueling, after the light
comes on, the amount of fuel that is added will be less than the
advertised capacity since there is fuel still in the tank. The ignition must
be in the ON position for this lamp to illuminate. The lamp will also
illuminate for several seconds after the ignition is turned to the ON
position regardless of the fuel level to ensure your bulb is working.
Anti-lock brake system (ABS) (if equipped)
Momentarily illuminates when the
ignition is turned to the ON
position. If the light remains on,
continues to flash or fails to
illuminate, have the system serviced
immediately. With the ABS light on, the anti-lock brake system is
disabled and normal braking is still effective unless the brake warning
light also remains illuminated with parking brake released.

Service engine soon
Your vehicle is equipped with a
computer that monitors the engine's
emission control system. This
system is commonly known as the
On Board Diagnostics System (OBD
II). The OBD II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD II system also assists the
service technician in properly servicing your vehicle.
TheService Engine Soonindicator light illuminates when the ignition is
first turned to the ON position to check the bulb. If it comes on after the
engine is started, one of the engine's emission control systems may be
malfunctioning. The light may illuminate without a driveability concern
being noted. The vehicle will usually be drivable and will not require
towing.
What you should do if the Service Engine Soon light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction.
Temporary malfunctions may cause yourService Engine Soonlight to
illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may misfire or run
poorly.)
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed and securely
tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel and/or properly installing and securely tightening
the gas cap. After three driving cycles without these or any other
temporary malfunctions present, theService Engine Soonlight should
turn off. (A driving cycle consists of a cold engine startup followed by
mixed city/highway driving.) No additional vehicle service is required.
If theService Engine Soonlight remains on, have your vehicle serviced
at the first available opportunity.

Engine coolant temperature gauge
Indicates the temperature of the engine coolant. At normal operating
temperature, the needle remains within the normal area (the area
between the ªHº and ªCº). If it enters the red section, the engine is
overheating. Stop the vehicle as soon as safely possible, switch off the
ignition and let it cool. Refer toEngine coolantin theMaintenance
and carechapter.
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level or mixture, the
gauge indication will not be accurate.
Never remove the radiator cap while the engine is running or
hot.

Driving with an automatic overdrive transaxle
Your automatic transaxle electronically controls the shift feel by using an
adaptive learning strategy. This feature is designed to optimize shift
smoothness. It is normal for your transaxle to shift firmly during the first
few hundred kilometers (miles) of operation until the adaptive strategy
has been learned. The adaptive learning strategy is maintained by power
from the battery. When the battery is disconnected or a new battery is
installed, the transaxle must relearn its adaptive strategy. Optimal
shifting will resume within a few hundred kilometers (miles) of
operation.
Your automatic overdrive transaxle
provides fully automatic operation in
either D (Overdrive) or with the
O/D OFF switch depressed. Driving
with the gearshift lever in D
(Overdrive) gives the best fuel economy for normal driving conditions.
For manual control, start in 1 (First) and then shift manually.
To put your vehicle in gear, start the
engine, depress the brake pedal,
then move gearshift lever out of P
(Park).
DRIVING THROUGH WATER
Do not drive quickly through standing water, especially if the depth is
unknown. Traction or brake capability may be limited and if the ignition
system gets wet, your engine may stall. Water may also enter your
engine's air intake and severely damage your engine.
If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
hubs.
Once through the water, always try the brakes. Wet brakes do not stop
the vehicle as effectively as dry brakes. Drying can be improved by
moving your vehicle slowly while applying light pressure on the brake
pedal.
Driving through deep water where the transaxle is submerged
may allow water into the transaxle and cause internal
transmission damage.

The fuel system may be under pressure. If the fuel filler cap is
venting vapor or if you hear a hissing sound, wait until it stops
before completely removing the fuel filler cap. Otherwise, fuel may
spray out and injure you or others.
If you do not use the proper fuel filler cap, excessive pressure or
vacuum in the fuel tank may damage the fuel system or cause
the fuel system to work improperly in a collision, which may result in
possible personal injury.
Automotive fuels can cause serious injury or death if misused or
mishandled.
Gasoline may contain benzene, which is a cancer-causing agent.
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. Fuel such as
gasoline is highly toxic and if
swallowed can cause death or
permanent injury. If fuel is
swallowed, call a physician immediately, even if no symptoms are
immediately apparent. The toxic effects of fuel may not be visible for
hours.
²Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind
can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.
Maintenance and care
216

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 vehicle is equipped with a threaded design fuel tank filler cap.
When installing the fuel filler cap, a ratcheting mechanism allows the cap
to be seated without overtightening.
Maintenance and care
217

When the fuel filler door is open, the left hand sliding door will
not open.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the fuel filler cap counterclockwise, using caution to
minimize the possibility of fuel spraying.
3. Remove the cap from the fuel filler pipe.
4. To install the cap, turn it clockwise until you hear at least three clicks.
If the ªService Engine Soonº indicator comes on and stays on when you
start the engine, the fuel filler cap may not be properly installed. Turn
off the engine, remove the cap, align the cap properly and reinstall it.
If you must replace the fuel filler cap, replace it with a fuel filler
cap that is designed for your vehicle. The customer warranty may
be void for any damage to the fuel tank or fuel system if the
correct genuine Ford or Motorcraft fuel filler cap is not used.
The fuel system may be under pressure. If the fuel filler cap is
venting vapor or if you hear a hissing sound, wait until it stops
before completely removing the fuel filler cap. Otherwise, fuel may
spray out and injure you or others.
If you do not use the proper fuel filler cap, excessive pressure or
vacuum in the fuel tank may damage the fuel system or cause
the fuel system to work improperly in a collision, which may result in
possible personal injury.
Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel is prohibited by law
and could damage your vehicle.
Do not use fuel containing methanol. It can damage critical fuel system
components.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based compounds containing MMT.
Repairs to correct the effects of using a fuel for which your vehicle was
not designed may not be covered by your warranty.
Maintenance and care
218

If you have run out of fuel:
²You may need to crank the engine several times after refueling before
the system starts 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 the
Instrumentationchapter.
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
chart in this ªOwner Guide.º 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.
