WARNING LIGHTS AND CHIMES
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 (OBD
II). This OBD II system protects the environment by ensuring that your
vehicle continues to meet government emission standards. The OBD II
system also assists the service technician in properly servicing your
vehicle.
TheCheck Engineindicator light illuminates when the ignition is first
turned to the ON 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 OBD II 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.

Safety belt
Momentarily illuminates when the
ignition is turned to the ON position
to remind you to fasten your safety
belts. For more information, refer to
theSeating and safety restraints
chapter.
Brake system warning
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. If the brake
warning lamp does not illuminate at
this time, seek service immediately.
Also illuminates when the parking brake is engaged. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately.
Anti-lock brake system (ABS)
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. 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 parking brake released.
Turn signal
Illuminates when the left or right
turn signal or the hazard lights are
turned on. If one or both of the
indicators stay on continuously or
flash faster, check for a burned-out
turn signal bulb. Refer toExterior bulbsin theMaintenance and care
chapter.

Safety belt extension assembly
If the safety belt assembly is too short, even when fully extended, 20 cm
(8 inches) can be added to the safety belt assembly by adding a safety
belt extension assembly (part number 611C22). Safety belt extension
assemblies can be obtained from your dealer at no cost.
Use only extensions manufactured by the same supplier as the safety
belt. Manufacturer identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if the safety belt is too
short for you when fully extended. Do not use extensions to change the
fit of the shoulder belt across the torso.

²and the electrical wiring which connects the components.
The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system warning (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 SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to theAir bag readiness
section in theInstrumentationchapter. Routine maintenance of the air
bag is not required.
A difficulty with the system is indicated by one or more of the following:
²The readiness light will either
flash or stay lit.
²The readiness light will not
illuminate immediately after
ignition is turned on.
²A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and light are repaired.
If any of these things happen, even intermittently, have the SRS 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 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.
Do not lean your head on the door, the side air bag could injure
you as it deploys from the side of the seatback.
Do not attempt to service, repair, or modify the air bag
Supplemental Restraint System, its fuses or the seat cover on a
seat containing an air bag. See your Ford or Lincoln Mercury dealer.
Seating and safety restraints

All occupants of the vehicle including the driver should always
wear their safety belts even when an air bag SRS is provided.
How does the side air bag system work?
The side air bag system consists of
the following:
²An inflatable nylon bag (air bag)
with a gas generator concealed
behind the outboard bolster of
the driver and front passenger
seatbacks.
²A special seat cover designed to
allow airbag deployment.
²The same warning light,
electronic control and diagnostic
unit as used for the front air
bags.
²Two crash sensors located under
the outboard side of the front
seats, attached to the floor.
Side air bags, in combination with
seat belts, can help reduce the risk
of severe injuries in the event of a
significant side impact collision.
The side air bags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the air bag on the side affected
by the collision will be inflated, even if the respective seat is not
occupied. The air bag was designed to inflate between the door panel
and occupant to further enhance the protection provided occupants in
side impact collisions.
The air bag SRS is designed to activate when the vehicle sustains
sufficient lateral deceleration sufficient to cause the sensors to close an
electrical circuit that initiates air bag inflation.

BRAKES
Your service brakes are self-adjusting. Refer to the maintenance guide
and or service 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 at 17 km/h (10
mph) 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 compensating 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.

ABS warning lamp
The
ABSwarning lamp in the instrument cluster momentarily illuminates
when the ignition is turned on and the engine is off. If the light does not
illuminate momentarily at start up, remains on or continues to flash, the
ABS needs to be serviced.
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 parking brake
released. (If your brake warning lamp illuminates, have your vehicle
serviced immediately).
Using ABS
²In an emergency or when maximum efficiency from the ABS is
required, apply continuous full force on the brake. The ABS will be
activated immediately, thus allowing you to retain full steering control
of your vehicle and, providing there is sufficient space, will enable you
to avoid obstacles and bring the vehicle to a controlled stop.
²The Anti-Lock system does not decrease the time necessary to apply
the brakes or always reduce stopping distance. Always leave enough
room between your vehicle and the vehicle in front of you to stop.
²We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.
Parking brake
Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, press the parking
brake pedal down until the pedal
stops.

TRANSMISSION OPERATION
Automatic transmission operation
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift from being moved from P (Park) unless the brake pedal is
depressed.
If you cannot move the gearshift out of P (Park) with the brake pedal
depressed:
1. Apply the parking brake, turn ignition key to LOCK, then remove the
key.
2. Insert the key and turn it to OFF. Apply the brake pedal and shift to N
(Neutral).
3. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift, it is
possible that a fuse has blown or the vehicle's brakelamps are not
operating properly. Refer toFuses and relaysin theRoadside
emergencieschapter.
Do not drive your vehicle until you verify that the brakelamps
are working.
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting between forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle for more than a few minutes. The
transmission and tires may be damaged or the engine may
overheat.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn off the ignition whenever you leave
your vehicle.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your dealer or a qualified service technician.

²Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
²Have the items listed in your Scheduled Maintenance Guide performed
according to the specified schedule.
The scheduled maintenance items listed in the Scheduled Maintenance
Guide are essential to the life and performance of your vehicle and to its
emissions system.
If other than Ford, Motorcraft or Ford-authorized parts are used for
maintenance replacements or for service of components affecting
emission control, such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and durability.
Do not park, idle, or drive your vehicle in dry grass or other dry
ground cover. The emission system heats up the engine
compartment and exhaust system, which can start a fire.
Illumination of the charging system warning light,Check Engine
indicator light or the temperature warning light, fluid leaks, strange
odors, smoke or loss of oil pressure, could indicate that the emission
control system is not working properly.
Exhaust leaks may result in entry of harmful and potentially
lethal fumes into the passenger compartment.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, items, sells,
leases, trades vehicles, or supervises a fleet of vehicles are not permitted
to intentionally remove an emission control device or prevent it from
working. Information about your vehicle's emission system is on the
Vehicle Emission Control Information Decal located on or near the
engine. This decal identifies engine displacement and gives some tune up
specifications.
Please consult your ªWarranty Guideº for complete emission warranty
information.
