2000 FORD E-450 sensor

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.
Safety belt pretensioner
Your vehicle is equipped with safety belt pretensioners at the driver and
front passenger seating positions.
The safety belt pretensioner is a device which removes excess webbing
from the safety belt system. The safety belt pretensioner uses the same
crash sensor system as the front air bag supplemental restraint system
(SRS). When the safety belt pretensioner deploys, webbing from the lap
and shoulder belt is tightened. The driver and front passenger seat belt
system (including retractors, buckles and height adjusters) must be
replaced if the vehicle is involved in a collision that results in
deployment of front air bags and safety belt pretensioners.
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
adjuster down. To raise the height
of the shoulder belt, slide the height
adjuster up. Pull down on the height
adjuster to make sure it is locked in
place.
Position the shoulder belt height adjusters so that the belt rests
across the middle of your shoulder. Failure to adjust the safety
belt properly could reduce the effectiveness of the seat belt and
increase the risk of injury in a collision.

AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
Your vehicle is equipped with a crash sensing and diagnostic module
which records information about the air bag and sensor systems. In the
event of a collision this module may save information related to the
collision including information about the air bag system and impact
severity. This information will assist Ford in the servicing of your vehicle
and may help Ford better understand real world collisions and further
improve the safety of future vehicles.
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 an air bag SRS is
provided.

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
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
near-frontal collisions, not rollover, side-impact, or rear-impacts unless
the collision causes sufficient longitudinal deceleration.

Several air bag system components get hot after inflation. Do not
touch them after inflation.
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.

Power distribution box
The power distribution box is located in the engine compartment. The
power distribution box contains high-current fuses that protect your
vehicle's main electrical systems from overloads.
Always disconnect the battery before servicing high current
fuses.
Always replace the cover to the Power Distribution Box before
reconnecting the battery or refilling fluid reservoirs.
If the battery has been disconnected and reconnected, refer to the
Batterysection of theMaintenance and carechapter.
