1998 LINCOLN MARK VIII fuel cap

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 check engine light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction. Have
your vehicle serviced at your first opportunity.
Temporary malfunctions may also cause yourcheck enginelight to
illuminate. Examples follow:
²The vehicle has run out of fuel. (The engine may misfire or run
poorly.)
²Poor fuel quality or water in the fuel.
²The fuel cap may not have been securely tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel and/or properly tightening the gas cap. After three
drive cycles without these or any other temporary malfunctions present,
thecheck enginelight should turn off.Novehicle service is required.
Light is blinking:
Engine misfire is occurring which could damage your catalytic converter.
You should drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced at the first available
opportunity.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Air bag readiness
Briefly illuminates when the ignition
is turned on. If the light fails to
illuminate, continues to flash or
remains on, have the system
serviced immediately.
Instrumentation
10

Odometer
Indicates the total kilometers
(miles) of the vehicle.
Fuel gauge
Displays approximately how much
fuel is in the fuel tank (when the
key is in the ON position). The fuel
gauge may vary slightly when the
vehicle is in motion. The ignition
should be in the OFF position while
the vehicle is being refueled. When
the gauge first indicates empty,
there is a small amount of reserve
fuel in the tank. When refueling the
vehicle from empty indication, the
amount of fuel that can be added
will be less than the advertised
capacity due to the reserve fuel.
ELECTRONIC MESSAGE CENTER
The electronic message center only
works when the ignition is in the
ON position.
The message center tells you about
the condition of your vehicle by
three methods:
²operator selectable features
²vehicle system status displays
²continuous warning reporting of monitored systems

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.
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 effects 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.
