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 Service Engine Soon
light illuminates
Light turns on solid:
This means that the OBD II system has detected a
malfunction.
Temporary malfunctions may cause yourService
Engine Soonlight 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, theService Engine Soonlight
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 theService Engine Soonlight 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.

Traction ControlYactive
Momentarily
illuminates when the
ignition is turned to
ON. It also illuminates
when the Traction Controlysystem begins applying
and releasing the brakes and adjusting the engine
characteristics to limit a wheelspin condition. It will
be lit for a minimum of four seconds or for the
duration of the Traction Controlyevent.
For more information, refer to theDrivingchapter.
Anti-lock brake system (ABS)
Momentarily illuminates
when the ignition is
turned to the ON
position. If the light
remains on, continues to flash or fails to illuminate,
have the system serviced immediately. With the ABS
light on, the anti-lock brake system is disabled and
normal braking is still effective unless the brake
warning light also remains illuminated with the
parking brake released.
Brake system warning
Momentarily illuminates
when the ignition is
turned to the ON
position. Also
illuminates if the parking brake is engaged. If brake
warning lamp does not illuminate at these times,
seek service immediately. Illumination after releasing
the parking brake indicates low brake fluid level and
the brake system should be inspected immediately.
Check coolant (if equipped)

Engine oil pressure gauge
This shows the engine
oil pressure in the
system. Sufficient
pressure exists as long
as the needle remains in the normal range (the area
between the ªLº and ªHº).
If the gauge indicates low pressure, stop the vehicle
as soon as safely possible and switch off the engine
immediately. Check the oil level. Add oil if needed
(refer toEngine oilin theMaintenance and care
chapter). If the oil level is correct, have your vehicle
checked at your dealership or by a qualified
technician.

used to purchase gasoline or similar items on the
same key ring as the PATS ignition key may cause
vehicle starting problems. If present, you need to
keep these objects from touching the PATS ignition
key while starting the engine. These objects cannot
damage the PATS ignition key, but can cause a
momentary problem if they are too close to the key
during engine start. If a problem occurs, turn the
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 SecuriLockykeys can be purchased from
your dealership and programmed to your
SecuriLockypassive anti-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 two seconds to indicate the
SecuriLockysystem is protecting your vehicle.
²When the ignition is turned to ON or START, the
theft indicator will light for three 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.

Important safety precautions
A computer system controls the engine's idle
revolutions per minute (RPM). When the engine
starts, the idle RPM runs faster to warm the engine.
If the engine idle speed does not slow down
automatically, have the vehicle checked. Do not
allow the vehicle to idle for more than 10 minutes at
high engine RPM.
Before starting the vehicle:
1. Make sure all vehicle occupants have buckled
their safety belts. For more information on safety
belts and their proper usage, refer to theSeating
and safety restraintschapter.
2. Make sure the headlamps and vehicle accessories
are off.
If starting a vehicle with an automatic transmission:
²Make sure the
parking brake is set.
²Make sure the gearshift is in P (Park).
If starting a vehicle with a manual transmission:
²Make sure the parking brake is set.
²Push the clutch
pedal to the floor.

If you ever smell exhaust fumes of any kind
inside your vehicle, have your dealer inspect
and fix your vehicle immediately. Do not drive if
you smell exhaust fumes. These fumes are harmful
and could kill you.
Have the exhaust and body ventilation systems
checked whenever:
²the vehicle is raised for service.
²the sound of the exhaust system changes.
²the vehicle has been damaged in a collision.
Engine exhaust, some of its constituents,
and certain vehicle components contain or
emit chemicals known to the State of California to
cause cancer, and birth defects or other
reproductive harm.
Important ventilating information
If the engine is idling while the vehicle is stopped in
an open area for long periods of time, open the
windows at least 2.5 cm (one inch).
Adjust the heating or air conditioning (if equipped)
to bring in fresh air.
Improve vehicle
ventilation by keeping
all air inlet vents clear
of snow, leaves and
other debris.

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-metal,º 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.
