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

The SecuriLockypassive anti-theft system is not
compatible with aftermarket remote start systems.
Use of these systems may result in vehicle starting
problems and a loss of security protection. Large
metallic objects or devices such as the Mobil
Speedpassyon the same key ring as your
SecuriLockykey may cause vehicle starting
problems. These objects and devices cannot damage
the SecuriLockykey, but can cause a momentary
problem if they are too close to the key when
starting the engine. If a problem occurs, turn
ignition off and restart the engine with all other
objects on the key ring held away from the
SecuriLockyignition key.
Spare SecuriLockykeys can be purchased from
your dealership and programmed to your
SecuriLockypassive anti-theft system. Refer to
Programming spare SecuriLockykeysfor more
information.
If one or both of your SecuriLockykeys are lost or
stolen and you want to ensure the lost or stolen key
will not operate your vehicle, bring your vehicle and
all available SecuriLockykeys to your dealership for
reinitialization.
Theft indicator
The theft indicator on the instrument cluster will
operate as follows:
²When the ignition is OFF, the theft indicator will
flash briefly every 2 seconds to indicate the
SecuriLockysystem is protecting your vehicle.
²When the ignition is turned to RUN or START, the
theft indicator will light for 3 seconds and then go
out. If the theft indicator stays on for an extended
period of time or flashes rapidly, have the system
serviced by your dealership or a qualified
technician.
Controls and features
61

controlled by automatically applying and releasing
the rear brakes in conjunction with engine torque
reductions. Engine torque reduction is realized via
the fully electronic spark and fuel injection systems.
This process is very sensitive to driving conditions
and very fast acting. The rear wheels ªsearchº for
optimum traction several times a second and
adjustments are made accordingly.
The Traction Controlysystem will allow your
vehicle to make better use of available traction on
slippery surfaces. The system is a driver aid which
makes your vehicle easier to handle primarily on
snow, ice covered and gravel roads.
During Traction
Controlyoperation,
the traction control
active light will
illuminate, you may hear an electric motor type of
sound coming from the engine compartment and the
engine will not ªrev-upº when you push further on
the accelerator. This is normal system behavior.
The Traction Controlyon/off switch, located in front
of the gearshift, illuminates when the system is OFF.
The Traction Controlysystem will revert to the ON
position every time the ignition is turned OFF and
ON.
If you should become stuck in snow or ice or on a
very slippery road surface, try switching the Traction
Controlysystem off. This may allow excess wheel
spin to ªdigº the vehicle out and enable a successful
ªrockingº maneuver.
If a system fault is detected the warning indicator
lamp is and your vehicle should be serviced.
STEERING
Your vehicle is equipped with power steering. Power
steering uses energy from the engine to help steer
the vehicle.

²If the oil level is
below the MIN mark,
add enough oil to
raise the level within
the MINÐMAX
range.
²Oil levels above the MAX mark may cause engine
damage. Some oil must be removed from the
engine by a service technician.
7. Put the indicator back in and ensure it is fully
seated.
Adding engine oil
1. Check the engine oil. For instructions, refer to
Checking the engine oilin this chapter.
2. If the engine oil level is not within the normal
range, add only certified engine oil of the
recommended viscosity. Remove the engine oil filler
cap and use a funnel to pour the engine oil into the
opening.
3. Recheck the engine oil level. Make sure the oil
level is not above the MAX mark on the engine oil
level indicator (dipstick).
4. Install the indicator and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the
filler cap clockwise until three clicks can be heard.
To avoid possible oil loss, DO NOT operate the
vehicle with the engine oil level indicator
and/or the engine oil filler cap removed.
Maintenance and care

BATTERY
Your vehicle is
equipped with a
Motorcraft
maintenance-free
battery which normally
does not require
additional water during
its life of service.
However, for severe usage or in high temperature
climates, check the battery electrolyte level. Refer to
the Scheduled Maintenance Guide for the service
interval schedules.
Keep the electrolyte level in each cell up to the
ªlevel indicatorº. Do not overfill the battery
cells.
If the electrolyte level in the battery is low, you can
add plain tap water to the battery, as long as you do
not use hard water (water with a high mineral or
alkali content). If possible, however, try to only fill
the battery cells with distilled water. If the battery
needs water often, have the charging system
checked.
If your battery has a cover/shield, make sure it
is reinstalled after the battery has been
cleaned or replaced.
For longer, trouble-free operation, keep the top of
the battery clean and dry. Also, make certain the
battery cables are always tightly fastened to the
battery terminals.
If you see any corrosion on the battery or terminals,
remove the cables from the terminals and clean with
a wire brush. You can neutralize the acid with a
solution of baking soda and water.

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 fuel tank filler cap has an indexed design with
a 1/8 turn on/off feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise 1/8
of a turn until it stops.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with
the notches on the filler pipe.
5. Turn the filler cap clockwise 1/8 of a turn until it
stops.
If the ªService Engine Soon/Check Engineº 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 fuel filler 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.
Maintenance and care

ªPremiumº unleaded gasoline is not recommended
(particularly in the United States) because it may
cause these problems to become more pronounced.
If the problems persist, see your dealer or a qualified
service technician.
It should not be necessary to add any aftermarket
products to your fuel tank if you continue to use a
high quality fuel.
Cleaner air
Ford approves the use of gasolines to improve air
quality, including reformulated gasolines that contain
oxygenates up to 10% ethanol or 15% MTBE.
Running out of fuel
Avoid running out fuel because this situation may
have an adverse affect on powertrain components.
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 theInstrumentation
chapter.
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.
