WARNING LIGHTS AND CHIMES
Check engine
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). This 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.
TheCheck Engineindicator 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 check engine light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction.
Temporary malfunctions may cause yourCheck Enginelight 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, theCheck Enginelight 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 theCheck Enginelight 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.
Fuel reset
Illuminates when the ignition key is
turned to the ON position and the
fuel pump shut-off switch has been
triggered. For more information,

special SecuriLockyelectronically coded keys provided with your
vehicle. Each time you start your vehicle, the SecuriLockykey is read
by the SecuriLockyanti-theft system. If the SecuriLockykey
identification code matches the code stored in the SecuriLocky
anti-theft system, the vehicle's engine is allowed to start. If the
SecuriLockykey identification code does not match the code stored in
the system or if a SecuriLockykey is not detected (vehicle theft
situation), the vehicle's engine will not operate.
Spare SecuriLockykeys can be purchased from your dealership and
programmed to your SecuriLockyanti-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.
Programming spare SecuriLockYkeys
Spare SecuriLockykeys can be purchased from your dealership and
programmed to your SecuriLockyanti-theft system (up to a total of 8
keys). Your dealership can program your new SecuriLockykey(s) to
your vehicle or you can do it yourself using the following simple
procedure. To program a new SecuriLockykey yourself, you will need
two previously programmed SecuriLockykeys (keys that already
operate your vehicle's engine). If two previously programmed
SecuriLockykeys are not available (one or both of your original keys
were lost or stolen), you must bring your vehicle to your dealership to
have the spare SecuriLockykey(s) programmed.

All occupants of the vehicle including the driver should always
wear their safety belts even when air bag SRS is provided.
Do not place objects or mount equipment on or near the air bag
cover on the steering wheel or in front seat areas that may come
into contact with a deploying air bag. Failure to follow this instruction
may increase the risk of personal injury in the event of a collision.
Do not attempt to service, repair, or modify the Air Bag
Supplemental Restraint System or its fuses. See your Ford or
Lincoln-Mercury dealer.
Children and air bags
For additional important safety
information, read all information on
safety restraints in this guide.
Children should always wear their
safety belts. Failure to follow these
instructions may increase the risk of
injury in a collision.
Air bag can kill or injure a
child in a child seat. If you
must use a forward-facing child
seat in the front seat, move seat
all the way back.

If the air bag is inflated,the air bag will not function again
and must be replaced immediately. If the air bag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
The SRS consists of:
²driver and passenger air bag modules (which include the inflators and
air bags),
²one or more impact and safing sensors,
²a readiness light and tone
²and the electrical wiring which connects the components.
The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system warning (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power and the air bag ignitors.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to theAir bag readiness
section in theInstrumentationchapter. Routine maintenance of the air
bag is not required.
A difficulty with the system is indicated by one or more of the following:
²The readiness light will either flash or stay lit.
²The readiness light will not
illuminate immediately after
ignition is turned on.
²A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a
collision.
