Safety belt maintenance
Check the safety belt systems periodically to make sure they work
properly and are not damaged. Check the safety belts to make sure there
are no nicks, wears or cuts. All safety belt assemblies, including
retractors, buckles, front seat belt buckle assemblies (slide bar)(if
equipped), shoulder belt height adjusters (if equipped), child safety seat
tether bracket assemblies (if equipped), and attaching hardware, should
be inspected after a collision. Ford recommends that all safety belt
assemblies used in vehicles involved in a collision be replaced. However,
if the collision was minor and a qualified technician finds that the belts
do not show damage and continue to operate properly, they do not need
to be replaced. Safety belt assemblies not in use during a collision should
also be inspected and replaced if either damage or improper operation is
noted.
Failure to replace the safety belt assembly under the above
conditions could result in severe personal injuries in the event of
a collision.
Refer toCleaning and maintaining the safety beltsin the
Maintenance and caresection.

If the air bag is inflated,the air bag will not function again
and must be replaced immediately. If the air bag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
The SRS consists of:
²driver and passenger air bag modules (which include the inflators and
air bags),
²one or more impact and safing sensors,
²a readiness light and tone
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.

Disposal of air bags and air bag equipped vehicles
For disposal of air bags or air bag equipped vehicles, see your local
dealership or qualified technician. Air bags MUST BE disposed of by
qualified personnel.
SAFETY RESTRAINTS FOR CHILDREN
Important child restraint precautions
You are required by law to use safety restraints for children in the U.S.
and Canada. If small children ride in your vehicle (generally children who
are four years old or younger and who weigh 18 kg [40 lbs] or less), you
must put them in safety seats made especially for children. Check your
local and state or provincial laws for specific requirements regarding the
safety of children in your vehicle.
Never let a passenger hold a child on his or her lap while the
vehicle is moving. The passenger cannot protect the child from
injury in a collision.
Always follow the instructions and warnings that come with any infant or
child restraint you might use.
When possible, place children in the rear seat of your vehicle. Accident
statistics suggest that children are safer when properly restrained in the
rear seating positions than in the front seating position.
Children and safety belts
Children who are too large for child safety seats (as specified by your
child safety seat manufacturer) should always wear safety belts.
Follow all the important safety restraint and air bag precautions that
apply to adult passengers in your vehicle.
If the shoulder belt portion of a combination lap and shoulder belt can
be positioned so it does not cross or rest in front of the child's face or
neck, the child should wear the lap and shoulder belt. Moving the child
closer to the center of the vehicle may help provide a good shoulder belt
fit.
If the shoulder belt cannot be properly positioned:
²move the child to one of the seats with a lap belt only (if equipped) or
²if the child is the proper size, restrain the child in a safety seat.

BRAKES
Your brakes are self-adjusting. Refer to the ``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 ``metal-to-metal'', ``continuous grinding'' or
``continuous squeal'' 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. If the vehicle has continuous vibration or shudder
while braking, felt mainly in the steering wheel, the vehicle most likely
needs service.
The ABS operates by detecting the
onset of wheel lock up during brake
applications and compensating for
this tendency. The front 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.
ABS warning lamp
The
ABSwarning lamp in the instrument cluster illuminates for about
five seconds when starting the vehicle. If an ABS fault is detected, the
Driving
104

light will remain on and your vehicle should be serviced as soon as
possible.
Normal braking is still effective
unless the BRAKE warning lamp is
also illuminated.
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.
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.
The BRAKE warning lamp in the
instrument cluster illuminates and
remains illuminated (when the
ignition is turned ON) until the
parking brake is released.

EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
²Use only unleaded fuel.
²Avoid running out of fuel.
²Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
²Have the services listed in your ``Service Guide'' performed according
to the specified schedule.
The Scheduled Maintenance Services listed in the ``Service Guide'' are
required because they are considered 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.
Watch for fluid leaks, strange odors, smoke, loss of oil pressure, the
charging system warning light, the ``Check Engine'' light or the
temperature warning light. These events could indicate that the emission
control system is not working properly.
If you smell exhaust fumes of any kind inside your vehicle, have
the dealer inspect and fix your vehicle immediately. Do not drive
if you smell exhaust fumes. These fumes are harmful and could kill
you.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
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
Maintenance and care
185

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 ``Warranty Guide'' for complete emission warranty
information.
Readiness for inspection/maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostic (OBD-II) system. If your ``check engine/service
engine soon'' light is on, reference the applicable light description in the
Warning Lights and Chimessection of your owners guide. Your vehicle
may not pass the I/M test with the ``check engine/service engine soon''
light on.
If the vehicle's powertrain system or its battery has just been serviced,
the OBD-II system is reset to a ``not ready for I/M test'' condition. To
ready the OBD-II system for I/M testing, a minimum of 30 minutes of city
and highway driving is necessary as described below:
²First, at least 10 minutes of driving on an expressway or highway.
²Next, at least 20 minutes driving in stop and go, city type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
