2001 FORD F150 Owners Manual

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 high quality fuel of the recommended octane 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.
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
Momentarily illuminates when the
ignition is turned ON. If the light
fails to illuminate, continues to flash
or remains on, have the system
serviced immediately.

Safety belt
Momentarily illuminates when the
ignition is turned to the ON position
to remind you to fasten your safety
belts. For more information, refer to
theSeating and safety restraints
chapter.
Brake system warning
Momentarily illuminates when the
ignition is turned to the ON
position. Also illuminates if the
parking brake is engaged. If the
brake warning lamp does not
illuminate at these times, seek service immediately. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately.
Anti-lock brake system (ABS)
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 the parking brake released.
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.

Charging system
Illuminates when the ignition is
turned to the ON position and the
engine is off. The light also
illuminates when the battery is not
charging properly, requiring
electrical system service.
Oil pressure/Engine coolant
This light will come on when the
key is in the ON position and the:
²engine coolant temperature is
very high
²engine oil pressure is low
The light serves as a notice that a system needs your attention and to
check the engine coolant temperature gauge and the engine oil pressure
gauge.
Refer toEngine coolant temperature gaugeandEngine oil pressure
gaugein this chapter for more information.
Transmission control indicator light (TCIL) (if equipped)

pushed turning the transmission overdrive function OFF. When the TCIL
(the word OFF on the gear shift) light is on, the transmission does not
operate in the overdrive mode, refer to theDrivingchapter for
transmission function and operation.
The light may also flash steadily if a transmission malfunction is
detected. If the light does not come on when the Transmission Control
Switch is depressed or if the light flashes steadily, have your vehicle
serviced as soon as possible, damage to the transmission could occur.

GAUGES
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.
A minimum of 22.2 L (six gallons) must be added or removed from the
fuel tank in order for the gauge to instantaneously update. If less than
six gallons is the change, the gauge will take between five to twenty
minutes to update.
Speedometer
Indicates the current vehicle speed.
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 engine immediately and let the
engine cool. Refer toEngine
coolantin theMaintenance and
carechapter.
Never remove the coolant reservoir cap while the engine is
running or hot.
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate. If the gauge enters the red section, the oil
pressure/engine coolant andCheck Engine/Service Engine Soon
indicators illuminate, refer toWhat you should know about fail-safe
coolingin theMaintenance and care chapter.

Engine oil pressure gauge
This shows the engine oil pressure
in the system. Sufficient pressure
exists as long as the needle remains
in the normal range (the area
between the ªLº and ªHº).
If the gauge indicates low pressure,
stop the vehicle as soon as safely
possible and switch off the engine
immediately. Check the oil level.
Add oil if needed (refer toEngine oilin theMaintenance and care
chapter). If the oil level is correct, have your vehicle checked at your
dealership or by a qualified technician.
