sensor HONDA S2000 2009 2.G Owners Manual

Your seat belt system includes lap/
shoulder belts in both seating
positions. The seat belts are also
equipped with automatic seat belt
tensioners.
This system uses the same sensors
as the front airbags to monitor
whether the seat belts are latched or
unlatched, and how much weight is
on the passenger’s seat (see page).
The seat belt system
includes an indicator on the
instrument panel and a beeper to
remind you and your passenger to
f asten your seat belts.
This system monitors the seat belts.
If you turn the ignition switch to the
ON (II) position bef ore your seat
belt is f astened, the beeper will
sound and the indicator will f lash. If
your seat belt is not f astened bef ore the beeper stops, the indicator will
stop f lashing but remain on.
If a passenger does not f asten their
seat belt, the indicator will come on
about 6 seconds af ter the ignition
switch is turned to the ON (II)
position.
If eitherthedriverorpassengerdoes
not f asten their seat belt, the beeper
will sound and the indicator will f lash
again at regular intervals.
When no one is sitting in the
passenger’s seat, or a child or small
adult is riding there, the indicator
should not come on and the beeper
should not sound.
If the indicator comes on or the
beeper sounds when the driver’s seat
belt is latched and there is no
passenger and no items on the
passenger’s seat, something may be
interf ering with the monitoring
system. Look f or and remove:
If no obstructions are found, have
your vehicle checked by a dealer.
Any object(s) touching the rear of
the seat-back.
Any objects hanging on the seat.
Any items under the passenger’s
seat.

Emergency backup power in case
your vehicle’s electrical system is
disconnected in a crash.
Your airbag system includes: An indicator on the dashboard that
alerts you that the passenger’s
airbag has been turned of f (see
page ).
A sophisticated electronic system
that continually monitors and
records inf ormation about the
sensors, the control unit, the
airbag activators, the seat belt
tensioners, and driver and
passenger seat belt use when the
ignition switch is in the ON (II)
position.
An indicator on the instrument
panel that alerts you to a possible
problem with your airbags,
sensors, or seat belt tensioners
(see page ). Weight sensors that monitor the
weight on the passenger’s seat. If
the weight is about 65 lbs (29 kg)
or less (the weight of an inf ant or
small child), the passenger’s
airbag will be turned off (see page ).
Two SRS (supplemental restraint
system) airbags. The driver’s
airbag is stored in the center of
the steering wheel; the passenger’s
airbag is stored in the dashboard.
Both are marked ‘‘SRS AIRBAG’’
(see page ).
A driver’s seat position sensor that
monitors the distance of the seat
f rom the airbag. If the seat is too
far forward, the airbag will inflate
with less f orce (see page ). Sensors that can detect whether
the driver’s seat belt and the
passenger’s seat belt are latched
or unlatched (see page ). Sensors that can detect a
moderate to severe front impact. Automatic seat belt tensioners
(see page ). 26

The total time for inflation and
def lation is one-tenth of a second, so
f ast that most occupants are not
aware that the airbags deployed until
they see them lying in their laps.
Although both airbags normally
inf late within a split second of each
other, it is possible f or only one
airbag to deploy.
This can happen if the severity of a
collision is at the margin, or
threshold, that determines whether
or not the airbags will deploy. In
such cases, the seat belt will provide
suf f icient protection, and the
supplemental protection of f ered by
the airbag would be minimal.
If you ever have a moderate to
severe f rontal collision, sensors will
detect the vehicle’s rapid
deceleration.
If the rate of deceleration is high
enough, the control unit will instantly
inflate the driver’s and passenger’s
airbags, at the time and with the
f orce needed. Only the driver’s airbag can deploy if
there is no passenger in the
passenger’s seat, or if the advanced
airbag system has turned the
passenger’s airbag of f (see page ).
During a f rontal crash, your seat belt
restrains your lower body and torso,
and the f ront airbag helps protect
your head and chest.
Af ter inf lating, the f ront airbags will
immediately def late, so they won’t
interf ere with the driver’s visibility,
or the ability to steer or operate
other controls.

In acrash, both stages
will ignite simultaneously to provide
the quickest and greatest protection.
In a crash, one stage will
ignite first, then the second stage
will ignite a split second later. This
provides longer airbag inf lation time
with a little less force.
After a crash, you may see what
looks like smoke. This is actually
powder f rom the airbag’s surf ace.
Although the powder is not harmf ul,
people with respiratory problems
mayexperiencesometemporary
discomf ort. If this occurs, get out of
the vehicle as soon as it is saf e to do
so.
Your f ront airbags are dual-stage
airbags. This means they have two
inf lation stages that can be ignited
sequentially or simultaneously,
depending on crash severity.
Your f ront airbags are also dual-
threshold airbags. Airbags with this
f eature have two deployment
thresholds that depend on whether
sensors detect the occupant is
wearing a seat belt or not.
If the occupant’s belt is
,
the airbag will deploy at a slightly
lower threshold, because the
occupant would need extra
protection.
If the occupant’s belt is , the
airbag will inf late at a slightly higher
threshold, when the airbag would be
needed to supplement the protection
provided by the seat belt.

If there is a problem with the sensor,
the SRS indicator will come on, and
the airbag will inf late in the normal
manner regardless of the driver’s
seating position.
Your airbags are also advanced
airbags. The main purpose of this
feature is to help prevent airbag-
caused injuries to short drivers and
children who ride in the passenger’s
seat.
For both advanced airbags to work
properly:
Occupants must sit upright and
wear their seat belts properly.
Failure to f ollow these instructions
could damage the sensors or prevent
them f rom working properly. Do not spill any liquids on or
under the seats, cover the sensors,
or put any objects or metal items
under the seats.
The driver’s advanced front airbag
system includes a seat position
sensor under the seat. If the seat is
too far forward, the airbag will
inf late with less f orce, regardless of
the severity of the impact.
Be aware that objects placed on the
passenger’s seat can also cause the
airbag to be turned off.
The passenger’s advanced airbag
system has weight sensors under the
seat. Although Honda does not
encourage carrying a child in the
passenger’s seat, if the sensors
detect the weight of an inf ant or
small child (up to about 65 lbs or 29
kg), the system will automatically
turn the passenger’s airbag of f .

If you see any of these indications,
the airbags and seat belt tensioners
may not work properly when you
need them.Be aware that objects placed on the
passenger’s seat can cause the
indicator to come on.
If no weight is detected in the
passenger’s seat, the airbag will be
automatically shut off. However, the
indicator will not come on.
This indicator alerts you that the
passenger’s airbag has been shut of f

65 lbs (29 kg) or less (the weight of

Take your vehicle to an
authorized dealer as soon as
possible. If you ignore this
indication, your airbags may not
operate properly. Together, airbags and
seat belts provide the best
protection.
Tampering could cause
the airbags to deploy, possibly
causing very serious injury. This could make the driver’s seat
position sensor or the passenger’s
weight sensors inef f ective. If it is
necessary to remove or modif y a
seat to accommodate a person
with disabilities, f irst contact
Honda Automobile Customer
Service at (800) 999-1009.
Even if your
airbags do not inflate, your dealer
should inspect the driver’s seat
position sensor, the passenger’s
weight sensors, the seat belt
tensioners, and all seat belts worn
during the crash to make sure
they are operating properly.
