2004 FORD THUNDERBIRD check engine light

WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works. If any light remains on after starting the vehicle, have the
respective system inspected immediately.
Emission system/Check engine:
The Check Engine indicator light
illuminates when the ignition is first
turned to the ON position to check
the bulb. Solid illumination after the engine is started indicates the On
Board Diagnostics System (OBD-II) has detected a malfunction. Refer to
On board diagnostics (OBD-II) in theMaintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could
damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and have your vehicle serviced
immediately.
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: Illuminates when
the fuel cap may not be properly
installed. Continued driving with
this light on may cause the Emission
system/Check engine warning light
to come on. Refer to Fuel Filler Capin theMaintenance and
Specifications chapter.

Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the ON position
when the engine is not running, or in a position between ON and START,
or by applying the parking brake when the ignition is turned to the ON
position. If the brake system warning light does not illuminate at this
time, seek service immediately from your dealership. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately by your servicing dealership.
Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your dealer immediately.
Anti-lock brake system: If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately. Normal
braking is still functional unless the brake warning light also is
illuminated.
Air bag readiness: If this light fails
to illuminate when ignition is turned
to ON, continues to flash or remains
on, have the system serviced
immediately. A chime will also
sound when a malfunction in the supplemental restraint system has been
detected.
Safety belt: Reminds you to fasten
your safety belt. A chime will also
sound to remind you to fasten your
safety belt.
Charging system: Illuminates when
the battery is not charging properly.

Door ajar: Illuminates when the
ignition is in the ON position and
any door or trunk is open.
Turn signal: Illuminates when the
left or right turn signal or the
hazard lights are turned on. If the
indicators flash faster, check for a burned out bulb.
High beams: Illuminates when the
high beam headlamps are turned on.
Electronic throttle control:
Illuminates when the engine has
defaulted to a ’limp-home ’operation.
Report the fault to a dealer at the
earliest opportunity.
Key-in-ignition warning chime: Sounds when the key is left in the
ignition in the OFF/LOCK or ACC position and the driver ’s door is
opened.
Headlamps on warning chime: Sounds when the headlamps or parking
lamps are on, the ignition is off (the key is not in the ignition) and the

2. The amber indicator light will begin to flash after 20 seconds. Without
releasing the HomeLinkbutton, follow step 2 in the “Programming ”
section.
For questions or comments, contact HomeLink at www.homelink.com
or 1–800 –355 –3515.
CONVERTIBLE
Articles stored in the convertible top stowage compartment may break
the rear glass window when the top is lowered.
Lowering the convertible top
The convertible top can be lowered with the side windows either up or
down.
Do not lower the top when the top material is wet.
If you raise and lower the convertible top several times in a row, the
motor will heat up, causing the thermal circuit breaker to open so that
the top will stop operating. The convertible top will operate again after
allowing the motor to cool several minutes.
To lower the convertible top:
1. Bring vehicle to a complete stop. Put the gearshift in the P (Park)
position.
The convertible top will operate with the key in the RUN position,
RUN/ACC position or in the accessory delay mode. It is recommended
that the vehicle ’s engine is running when lowering the top to prevent
draining the battery.
2. Check the convertible top stowage compartment behind the seat to be
sure it is empty and ready to receive the top.
3. Press the button on the
convertible top handle and pull the
handle down and forward to release
the clamps from the windshield
header.

Driver Controls

During Traction Control
operation, 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 “rev-up ”when you push
further on the accelerator. This is normal system behavior and should be
no reason for concern.
The Traction Control
switch,
located on the left-hand side of the
instrument panel, has an indicator
light that illuminates when the
system is off. The Traction Control

system will automatically turn on
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 Control
system off. This may allow
excess wheel spin to “dig ”the vehicle out and enable a successful
“ rocking ”maneuver.
If a system fault is detected, the traction control switch ’s OFF indicator
will illuminate and your vehicle should be serviced.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of a Traction Control

event is an indication that at least some of the tires have exceeded
their ability to grip the road; this may lead to an increased risk of loss
of vehicle control, vehicle rollover, personal injury and death. If you
experience a severe road event, SLOW DOWN.
STEERING
To prevent damage to the power steering system:
• Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running.
• Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
• an improperly inflated tire

To reduce the risk of personal injury, make sure the engine is
cool before unscrewing the coolant pressure relief cap. The
cooling system is under pressure; steam and hot liquid can come out
forcefully when the cap is loosened slightly.
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (a translucent plastic bottle).
Slowly turn cap counterclockwise (left) until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Fill the coolant reservoir slowly with the proper coolant mixture (see
above), to within the “cold fill range ”or the “cold full ”level on the
reservoir. If you removed the radiator cap in an overflow system, fill the
radiator until the coolant is visible and radiator is almost full.
6. Replace the cap. Turn until tightly installed. (Cap must be tightly
installed to prevent coolant loss.)
After any coolant has been added, check the coolant concentration, refer
to Checking Engine Coolant section. If the concentration is not 50/50
(protection to –34 °F/ –36 °C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 liter (1.0 quart) of engine coolant per
month, have your dealer check the engine cooling system. Your cooling
system may have a leak. Operating an engine with a low level of coolant
can result in engine overheating and possible engine damage.
Recycled engine coolant
Ford Motor Company does NOT recommend the use of recycled engine
coolant in vehicles originally equipped with Motorcraft Premium Gold
Engine Coolant since a Ford-approved recycling process is not yet
available.
Used engine coolant should be disposed of in an appropriate
manner. Follow your community ’s regulations and standards for recycling
and disposing of automotive fluids.
