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.

Controls and features

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.
Safety belt warning light and
indicator chime
The seat belt warning light
illuminates in the instrument
cluster and a chime sounds to
remind the occupants to fasten
their safety belts.

Conditions of operation
If... Then...
The driver's safety belt is not
buckled before the ignition key
is turned to ON...The safety belt warning light
illuminates for one to two minutes and
the warning chime sounds for four to
eight seconds.
The driver's safety belt is
buckled while the indicator
light is illuminated and the
warning chime is sounding...The safety belt warning light turns off.
The driver's safety belt is
buckled before the ignition key
is turned to ON...The safety belt warning light remains
off.
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.

If the air bag is inflated,
the air bag will not
function again and must be
replaced immediately.Ifthe
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
readinesssection in the
Instrumentationchapter. Routine
maintenance of the air bag is not
required.

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 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
