sensor FORD EXCURSION 2000 1.G Owners Manual

The reverse sensing system detects
obstacles within approximately 1.8
meters (5.9 ft.) of the rear bumper
with a decreased coverage area at
the outer corners of the bumper,
(refer to the figures for approximate
zone coverage areas). As you move
closer to the obstacle, the rate of
the tone increases. When the
distance to the obstacle is less than
25.0 cm (10 in.), the tone will sound
continuously. If the system detects a
stationary or receding object further
than 25.0 cm (10 in.) from the side
of the vehicle, the tone will sound
for only three seconds. Once the
system detects an object
approaching, the tone will sound
again.
The reverse sensing system is
automatically enabled when the gear
selector is placed in R (Reverse)
and the ignition is ON. A reverse
sensing control allows the driver to
disable the reverse sensing system when the ignition is ON, and the gear
selector is in R (Reverse).
The OFF indicator remains illuminated when the system is disabled. The
system defaults to ON every time the reverse gear is selected. Press the
control to disable or enable the system.
The indicator will remain illuminated to indicate a failure of the reverse
sensing system.
Always keep the sensors (located on the rear bumper/fascia) free
from dirt, snow and ice (do not clean the sensors with sharp
objects). These elements may cause the system to operate
inaccurately.
If the vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles.

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.

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.
Seating and safety restraints
97

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, contact with
a deploying air bag may also cause 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
²diagnostic module
Seating and safety restraints
98

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 (including
pretensioners)
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.
