2004 FORD FOCUS service indicator

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.
Check engine:TheCheck 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
OBD-IIin theMaintenance and Specificationschapter. 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 Check
engine warning light to come on,
refer toFuel filler capin theMaintenance and Specificationchapter.
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.

key chain may cause vehicle starting issues. You need to prevent these
objects from touching the coded key while starting the engine. These
objects will not cause damage to the coded key, but may cause a
momentary issue if they are too close to the key when starting the
engine. If a problem occurs, turn the ignition off, remove all objects on
the key chain away from the coded key and restart the engine.
Theft indicator
The theft indicator is located on the instrument panel, above the hazard
flashers control.
•When the ignition is in the OFF position, the indicator will flash once
every 2 seconds to indicate the SecuriLock
system is functioning as
a theft deterrent.
•When the ignition is in the ON position, the indicator will glow for 3
seconds, then turn off, to indicate normal system functionality.
If a problem occurs with the SecuriLock
system, the indicator will flash
rapidly or glow steadily when the ignition is in the ON position. If this
occurs, the vehicle should be taken to an authorized dealer for service.
Replacement keys
If your keys are lost or stolen and you don’t have an extra coded key,
you will need to have your vehicle towed to a dealership. The key codes
need to be erased from your vehicle and new coded keys will need to be
programmed.
Replacing coded keys can be very costly. Store an extra programmed key
away from the vehicle in a safe place to help prevent any
inconveniences. Please visit an authorized dealer to purchase additional
spare or replacement keys.
Programming spare keys
You can program your own coded keys to your vehicle. Please read and
understand the entire procedure before you begin.
Tips:
•A maximum of eight keys can be coded to your vehicle.
•Only use Securilock
keys.
•You must have two previously programmed coded keys (keys that
already operate your vehicle’s engine) and the new unprogrammed
key(s) readily accessible.
•If two previously programmed coded keys are not available, you must
take your vehicle to your dealer to have the spare key(s)
programmed.

•diagnostic module.
•and the electrical wiring which connects the components.
The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system wiring (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 supplemental restraint system uses a warning indicator in the
instrument cluster or a back-up tone to indicate the condition of the
system. Refer to theWarning lightsection in theInstrument cluster
chapter. Routine maintenance of the air bag is not required.
A difficulty with the system is indicated by one or more of the following:
•The readiness light (same light
for front and side air bag system)
will either flash or stay lit.
•The readiness light will not
illuminate immediately after ignition is turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the supplemental
restraint system serviced at your dealership or by a qualified technician
immediately. Unless serviced, the system may not function properly in
the event of a collision.
Side air bag system (if equipped)
Do not place objects or mount equipment on or near the air bag
cover on the side of the seatbacks of the front seats or in front
seat areas that may come into contact with a deploying air bag. Failure
to follow these instructions may increase the risk of personal injury in
the event of a collision.
Do not use accessory seat covers. The use of accessory seat
covers may prevent the deployment of the side air bags and
increase the risk of injury in an accident.

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“level indicator”.
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.
Batteries normally produce explosive gases which can cause
personal injury. Therefore, do not allow flames, sparks or lighted
substances to come near the battery. When working near the battery,
always shield your face and protect your eyes. Always provide proper
ventilation.

If the“Service Engine Soon/Check Engine”indicator comes on and stays
on after 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.
If you do not use the proper fuel filler cap, excessive pressure or
vacuum in the fuel tank may damage the fuel system or cause
the fuel cap to disengage in a collision, which may result in possible
personal injury.
Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel is prohibited by law
and could damage your vehicle.
Do not use fuel containing methanol. It can damage critical fuel system
components.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based additives.
Repairs to correct the effects of using a fuel for which your vehicle was
not designed may not be covered by your warranty.
Octane recommendations
Your vehicle is designed to use
“Regular”unleaded gasoline with
pump (R+M)/2 octane rating of 87.
We do not recommend the use of
gasolines labeled as“Regular”that
are sold with octane ratings of 86 or lower in high altitude areas.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your dealer or a qualified
service technician to prevent any engine damage.

Fuel quality
If you are experiencing starting, rough idle or hesitation driveability
problems during a cold start, try a different brand of unleaded gasoline.
“Premium”unleaded gasoline is not recommended for vehicles designed
to use“Regular”unleaded gasoline 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 high quality fuel of the recommended octane
rating. Aftermarket products could cause damage to the fuel system.
Repairs to correct the effects of using an aftermarket product in your
fuel may not be covered by your warranty.
Many of the world’s automakers approved the World-wide Fuel Charter
that recommends gasoline specifications to provide improved
performance and emission control system protection for your vehicle.
Gasolines that meet the World-wide Fuel Charter should be used when
available. Ask your fuel supplier about gasolines that meet the
World-wide Fuel Charter.
Cleaner air
Ford endorses the use of reformulated“cleaner-burning”gasolines to
improve air quality.
Running out of fuel
Avoid running out of fuel because this situation may have an adverse
affect on powertrain components.
If you have run out of fuel:
•You may need to cycle the ignition from OFF to ON several times after
refueling, to allow the fuel system to pump the fuel from the tank to
the engine.
•The
indicator may come on. For more information on the“Check
Engine”indicator, refer to theInstrument Clusterchapter.
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.
