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 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.
Instrumentation

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.
Check fuel cap (if equipped)
Momentarily
illuminates when the
ignition is turned to
the ON position to
ensure your bulb is working. When this light turns
on, check the fuel filler cap. Continuing to operate
the vehicle with the check fuel cap light on, can
activate theService Engine Soon/Check Engine
warning light. When the fuel filler cap is properly
re-installed, the light(s) will turn off after a period of
normal driving. This period will vary depending on
driving conditions.
It may take a long period of time for the
system to detect an improperly installed fuel
filler cap.
For more information, refer toFuel filler capin the
Maintenance and carechapter.
Low fuel
Illuminates as an early
reminder of a low fuel
condition indicated on
the fuel gauge (refer to
Fuel 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.

O/D off (if equipped)
Illuminates when the
Transmission Control
Switch (TCS), refer to
Overdrive controlin
theControls and Featureschapter, has been
pushed turning the transmission overdrive function
OFF. When the light is on, the transmission does not
operate in the overdrive mode, refer to theDriving
chapter 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.
Traction ControlYactive
For more information,
refer to theDriver
controlschapter.
Momentarily illuminates when the ignition is turned
to ON. It also illuminates when the Traction
Controlysystem begins applying and releasing the
brakes and adjusting the engine characteristics to
limit a wheelspin condition. It will be lit for a
minimum of four seconds or for the duration of the
Traction Controlyevent.
For more information, refer to theDrivingchapter.
Anti-lock brake system (ABS)
Momentarily illuminates
when the ignition is
turned to the ON
position to indicate a
system check. 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.

GAUGES
Base instrument cluster gauges
Optional instrument cluster 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 or after refueling. 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 an empty
indication, the amount of fuel that can be added will
be less than the advertised capacity due to the
reserve fuel.

position. If the pointer
moves and stays outside the normal operating range
(as indicated by arrows), have the vehicle's electrical
system checked as soon as possible.
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.

touching thecoded keyignition key while starting
the engine. These objects and devices cannot damage
thecoded keyignition key, but can cause a
NOÐSTART condition if they are too close to the key
during engine start. If a problem occurs, turn ignition
OFF and restart the engine with all other objects on
the key ring held away from the ignition key. Check
to make sure thecoded keyignition key is an
approved Fordcoded keyignition key.
If your keys are lost or
stolen you will need to
do the following:
²
Use your spare key
to start the vehicle. or
²Have your vehicle towed to a dealership or
locksmith. The key codes will need to be erased
from your vehicle and new key codes will need to
be re-coded.
Replacing coded keys can be very costly and you
may want to store an extra programmed key away
from the vehicle in a safe place to prevent an
unforeseen inconvenience.
The correctcoded keykey must be used for your
vehicle. The use of the wrong type ofcoded key
key may lead to a ªNO-STARTº condition.
If an unprogrammed key is used in the ignition
it will cause a ªNO STARTº condition.
Programming spare keys
A maximum of eight keys can be coded to your
vehicle. Only SecuriLockykeys can be used. To
program acoded keyyourself, you will need two
previously programmedcoded keys(keys that
already operate your vehicle's engine) and the new
unprogrammed key(s) readily accessible for timely
implementation of each step in the procedure.
If two previously programmed coded keys are not
available, you must bring your vehicle to your
dealership to have the spare coded key(s)
programmed.

Important safety precautions
A computer system controls the engine's idle
revolutions per minute (RPM). When the engine
starts, the idle RPM runs faster to warm the engine.
If the engine idle speed does not slow down
automatically, have the vehicle checked. Do not
allow the vehicle to idle for more than 10 minutes at
high engine RPM.
Before starting the vehicle:
1. Make sure all vehicle occupants have buckled
their safety belts. For more information on safety
belts and their proper usage, refer to theSeating
and safety restraintschapter.
2. Make sure the headlamps and vehicle accessories
are off.
If starting a vehicle with an automatic transmission:
²Make sure the
parking brake is set.
²Make sure the gearshift is in P (Park).
If starting a vehicle with a manual transmission:
²Make sure the parking brake is set.
²Push the clutch
pedal to the floor.

until the key turns
freely. This condition may occur when:
²front wheels are turned
²front wheel is against the curb
²steering wheel is turned when getting in or out of
the vehicle
Make sure the corresponding lights illuminate or
illuminate briefly. If a light fails to illuminate, have
the vehicle serviced.
²If the driver's safety belt is fastened, the
light
may not illuminate.
