WARNING LIGHTS AND CHIMES
Engine coolant temperature
Illuminates when the engine coolant
temperature is high. Stop the
vehicle as soon as safely possible,
switch off the engine and let it cool.
Never remove the coolant
recovery cap while the
engine is running or hot.
Refer toEngine coolantin theMaintenance and carechapter. If light
stays on or continues to turn on after the vehicle warms up, have your
vehicle serviced.
This light also illuminates briefly when the ignition key is turned to RUN.
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. This system protects the environment by
ensuring that your vehicle continues to meet government emission
standards. The system also assists the service technician in properly
servicing your vehicle.
TheCheck Engineindicator light illuminates when the ignition is first
turned to the RUN 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 On Board Diagnostics System 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 high quality fuel of the recommended octane 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.

If there is any anti-theft problem with your vehicle, ensureALL coded
keysfor that vehicle are brought to the dealership, to aid in
troubleshooting.
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, electronic devices on the key chain that can be used to purchase
gasoline or similar items, or a second key on the same key ring as the
PATS ignition key may cause vehicle starting concern and record DTC's
under certain conditions. If present, you need to keep these objects from
touching the PATS ignition key while starting the engine. These objects
and devices cannot damage the PATS ignition key, but can cause a
momentary concern if they are too close to the key during engine start. If
a problem occurs, turn ignition OFF and restart the engine with all other
objects on the key ring held away from the ignition key. Check to make
sure the encoded ignition key is an approved Ford encoded ignition key.
Spare coded keys can be purchased from your dealership and
programmed to your anti-theft system. Refer toProgramming spare
SecuriLockykeysfor more information.
If one or both of your coded keys 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 coded keys to your dealership for reinitialization.
Theft indicator
When the ignition is turned to RUN or START, the theft indicator in the
instrument cluster will light for three seconds and then go out (indicates
proper anti-theft system operation). If the key is in the ignition and 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 coded keys can be purchased from your dealership and
programmed to your anti-theft system (up to a total of eight keys). Your
dealership can program your new coded key(s) to your vehicle or you
can do it yourself using the following simple procedure. To program a
new coded key yourself, you will need two previously programmed coded
keys (keys that already operate your vehicle's engine). If two previously
programmed coded keys 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 coded key(s) programmed.
Controls and features

BRAKES
Your service brakes are self-adjusting. Refer to the scheduled
maintenance guide for scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle's brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a ªmetal-to-metalº, ªcontinuous grindingº or
ªcontinuous squealº sound is present while braking, the brake linings
may be worn-out and should be inspected by a qualified service
technician.
Anti-lock brake system (ABS)
On vehicles equipped with an anti-lock braking system (ABS), a noise
from the hydraulic pump motor and pulsation in the pedal may be
observed during ABS braking events. Pedal pulsation coupled with noise
while braking under panic conditions or on loose gravel, bumps, wet or
snowy roads is normal and indicates proper functioning of the vehicle's
anti-lock brake system. The ABS performs a self-check after you start
the engine and begin to drive away. A brief mechanical noise may be
heard during this test. This is normal. If a malfunction is found, the ABS
warning light will come on. If the vehicle has continuous vibration or
shudder in the steering wheel while braking, the vehicle should be
inspected by a qualified service technician.
The ABS operates by detecting the
onset of wheel lockup during brake
applications and compensates for
this tendency. The wheels are
prevented from locking even when
the brakes are firmly applied. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during hard braking with loss of front braking
traction.

Driving conditions which may activate AdvanceTracyinclude:
²Taking a turn too fast
²Evasively maneuvering to avoid an accident, pedestrian or obstacle
²Hitting a patch of ice
²Changing lanes on a snow-rutted road
²Entering a snow-free road from a snow-covered side street
²Entering a paved road from a gravel road
²Hitting a curb while turning
²Driving on slick surfaces
The AdvanceTracysystem defaults to ON when the engine is started.
The system does not work when the vehicle is traveling backwards. In
reverse, ABS and Traction Controlywill continue to function. The
system uses ABS and Traction Controly(including control of the
engine) as well as its more advanced controls to enhance vehicle
stability.
The AdvanceTracyon/off control
button allows the driver to control
the availability of the Traction
Controlyand AdvanceTracy
system. This is independent of the
ABS function, which canNOTbe
switched off by the driver. The
AdvanceTracysystem status is
indicated by a warning indicator
light with a ªsliding carº icon in the
instrument cluster that will flash
when the system is active and an indicator light in the control button
that will illuminate when the system is turned OFF. In vehicles with a
message center (if equipped), the message ªADVANCETRAC OFFº is
displayed. If a failure is detected in the AdvanceTracysystem the
warning indicator light in the instrument cluster will stay ON. If the
warning indicator light in the instrument cluster remains ON while the
engine is running, have the system serviced immediately.
The AdvanceTracysystem continually monitors and checks all sensors
used in improving the stability of the vehicle. Some drivers may notice a
slight movement of the brake pedal when the system checks itself.
