2. To unfasten, push the release
button and remove the tongue from
the buckle.
The front and rear outboard safety restraints in the vehicle are
combination lap and shoulder belts. The front and rear seat passenger
outboard safety belts have two types of locking modes described below:
Vehicle sensitive mode
The vehicle sensitive mode is the normal retractor mode, allowing free
shoulder belt length adjustment to your movements and locking in
response to vehicle movement. For example, if the driver brakes
suddenly or turns a corner sharply, or the vehicle receives an impact of 8
km/h (5 mph) or more, the combination safety belts will lock to help
reduce forward movement of the driver and passengers.
Automatic locking mode
In this mode, the shoulder belt is automatically pre-locked. The belt will
still retract to remove any slack in the shoulder belt.
The automatic locking mode is not available on the driver safety belt.
When to use the automatic locking mode
²When a tight lap/shoulder fit is desired.
²Anytimea child safety seat is installed in a passenger front or
outboard rear seating position (if equipped). Refer toSafety
Restraints for ChildrenorSafety Seats for Childrenlater in this
chapter.

How to use the automatic locking mode
²Buckle the combination lap and
shoulder belt.
²Grasp the shoulder portion and
pull downward until the entire
belt is extracted.
²Allow the belt to retract. As the belt retracts, you will hear a clicking
sound. This indicates the safety belt is now in the automatic locking
mode.
How to disengage the automatic locking mode
Disconnect the combination lap/shoulder belt and allow it to retract
completely to disengage the automatic locking mode and activate the
vehicle sensitive (emergency) locking mode.
²This vehicle has a seat belt system with an energy management
feature at the front seating positions to help further reduce the risk of
injury in the event of a head-on collision.
Seating and safety restraints

²This seat belt system has a retractor assembly that is designed to pay
out webbing in a controlled manner. This feature is designed to help
reduce the belt force acting on the occupant's chest.
After any vehicle collision, the seat belt system at all outboard
seating positions (except driver, which has no ªautomatic locking
retractorº feature) must be checked by a qualified technician to verify
that the ªautomatic locking retractorº feature for child seats is still
functioning properly, in addition to other checks for proper seat belt
system function.
BELT AND RETRACTOR ASSEMBLY MUST BE REPLACED if
the seat belt assembly ªautomatic locking retractorº feature or
any other seat belt function is not operating properly when checked
according to the procedures in Workshop Manual.
Failure to replace the Belt and Retractor assembly could
increase the risk of injury in collisions.
Front safety belt height adjustment
Your vehicle has safety belt height
adjustments for the driver and front
passenger. Adjust the height of the
shoulder belt so the belt rests
across the middle of your shoulder.
To lower the shoulder belt height,
push the button and slide the height
control down. To raise the height of
the shoulder belt, slide the height
adjuster up. Pull down on the height
adjustment assembly to make sure it
is locked in place.
Position the shoulder belt height adjuster so that the belt rests
across the middle of your shoulder. Failure to adjust the safety
belt properly could reduce the effectiveness of the safety belt and
increase the risk of injury in a collision.

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

Safety belt maintenance
Inspect the safety belt systems periodically to make sure they work
properly and are not damaged. Inspect the safety belts to make sure
there are no nicks, wears or cuts, replacing if necessary. 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 inspect and if necessary 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.

Important supplemental restraint system (SRS) precautions
The supplemental restraint system
is designed to work with the safety
belt to help protect the driver and
right front passenger from certain
upper body injuries.
Air bags DO NOT inflate slowly or
gently and the risk of injury from a
deploying air bag is greatest close to
the trim covering the air bag
module.
All occupants of the vehicle including the driver should always
properly wear their safety belts even when air bag SRS is
provided.
Always transport children 12 years old and under in the back
seat and always use appropriate child restraints.
NHTSA recommends a minimum distance of at least 25 cm (ten
[10] inches) between an occupant's chest and the air bag
module.
Steps you can take to properly position yourself away from the airbag:
²Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
²Recline the seat slightly (one or two degrees) from the upright
position.
Do not put anything on or over the air bag module. Placing
objects on or over the air bag inflation area may cause those
objects to be propelled by the air bag into your face and torso causing
serious injury.

Do not attempt to service, repair, or modify the Air Bag
Supplemental Restraint System or its fuses. See your Ford or
Lincoln-Mercury dealer.
Children and air bags
For additional important safety
information, read all information on
safety restraints in this guide.
Children must always be properly
restrained. Accident statistics
suggest that children are safer when
properly restrained in the rear
seating positions than in the front
seating position. Failure to follow
these instructions may increase the
risk of injury in a collision.
Air bags can kill or injure a
child in a child seat.
NEVERplace a rear-facing child
seat in front of an active air bag. If
you must use a forward-facing
child seat in the front seat, move
the seat all the way back.
How does the air bag supplemental restraint system work?
The air bag SRS is designed to
activate when the vehicle sustains
sufficient longitudinal deceleration
sufficient to cause the sensors to
close an electrical circuit that
initiates air bag inflation.
The fact that the air bags did not
inflate in a collision does not mean
that something is wrong with the
system. Rather, it means the forces
were not of the type sufficient to
cause activation. Air bags are designed to inflate in frontal and
Seating and safety restraints
127

near-frontal collisions, not rollover, side-impact, or rear-impacts.
The air bags inflate and deflate
rapidly upon activation. After air bag
deployment, it is normal to notice a
smoke-like, powdery residue or
smell the burnt propellant. This may
consist of cornstarch, talcum
powder (to lubricate the bag) or
sodium compounds (e.g., baking
soda) that result from the
combustion process that inflates the
air bag. Small amounts of sodium
hydroxide may be present which
may irritate the skin and eyes, but
none of the residue is toxic.
While the system is designed to help
reduce serious injuries, it may also
cause minor burns, abrasions, swelling or temporary hearing loss.
Because air bags must inflate rapidly and with considerable force, there
is the risk of death or serious injuries such as fractures, facial and eye
injuries or internal injuries, particularly to occupants who are not
properly restrained or are otherwise out of position at the time of air bag
deployment. Thus, it is extremely important that occupants be properly
restrained as far away from the air bag module as possible while
maintaining vehicle control.
Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the air bag is deployed,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
