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:
TheCheck Engineindicator 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 toFuel Filler Capin theMaintenance and
Specificationschapter.

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.

RADIO RECEPTION FACTORS
There are three factors that can effect radio reception:
•Distance/strength: The further you travel from an FM station, the
weaker the signal and the weaker the reception.
•Terrain: Hills, mountains, tall buildings, power lines, electric fences,
traffic lights and thunderstorms can interfere with your reception.
•Station overload: When you pass a broadcast tower, a stronger signal
may overtake a weaker one and play while the weak station frequency
is displayed.
CD/CD PLAYER CARE
Do:
•Handle discs by their edges only. Never touch the playing surface.
•Inspect discs before playing. Clean only with an approved CD cleaner
and wipe from the center out.
Don’t:
•Expose discs to direct sunlight or heat sources for extended periods
of time.
•Insert more than one disc into each slot of the CD changer magazine.
•Clean using a circular motion.
CD units are designed to play commercially pressed 12 cm (4.75
in) audio compact discs only. Due to technical incompatibility,
certain recordable and re-recordable compact discs may not
function correctly when used in Ford CD players. Irregular
shaped CDs, CDs with a scratch protection film attached, and CDs
with homemade paper (adhesive) labels should not be inserted
into the CD player. The label may peel and cause the CD to
become jammed. It is recommended that homemade CDs be
identified with permanent felt tip marker rather than adhesive
labels. Ball point pens may damage CDs. Please contact your
dealer for further information.
AUDIO SYSTEM WARRANTY AND SERVICE
Refer to theWarranty Guidefor audio system warranty information. If
service is necessary, see your dealer or qualified technician.

SECURILOCKPASSIVE ANTI-THEFT SYSTEM
SecuriLock
passive anti-theft system is an engine immobilization
system. This system is designed to prevent the engine from being started
unless acoded key programmed to your vehicleis used. The use of
the wrong type of coded key may lead to a“no-start”condition.
Your vehicle comes with two coded keys; additional coded keys may be
purchased from your dealer. The dealer can program your spare keys to
your vehicle or you can program the keys yourself. Refer to
Programming spare keysfor instructions on how to program the coded
key.
Note:The SecuriLock
passive anti-theft system is not compatible with
non-Ford aftermarket remote start systems. Use of these systems may
result in vehicle starting problems and a loss of security protection.
Note:Large metallic objects, electronic devices that are used to
purchase gasoline or similar items, or a second coded key on the same
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 top of the instrument panel.
•When the ignition is in the RUN position, the indicator will glow for 3
seconds 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 RUN position. If this
occurs, the vehicle should be taken to an authorized dealer for service.

Automatic arming
The vehicle is armed immediately
after switching the ignition to the 2
(OFF) position.
Automatic disarming
Switching the ignition to the 4 (RUN) position with acoded keydisarms
the vehicle.
•The
THEFTindicator will illuminate for three seconds and then go
out.
•If the
THEFTindicator stays on for an extended period of time or
flashes rapidly, have the system serviced by your dealer.
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.
