2008 HONDA CIVIC sensor

During a frontal crash, your seat belt
restrains your lower body and torso,
and the f ront airbag helps protect
your head and chest.
Although both airbags normally
inf late within 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.
Only the driver’s airbag will deploy if
there is no passenger in the f ront
seat, or if the advanced airbag
system has turned the passenger’s
airbag off (see page ).
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
inf late the driver’s and f ront
passenger’s airbags, at the time and
with the f orce needed.
Emergency backup power in case
your vehicle’s electrical system is
disconnected in a crash.
An indicator on the dashboard that
alerts you that the passenger’s
f ront airbag has been turned of f
(see page ).
An indicator on the instrument
panel that alerts you that the
passenger’s side airbag has been
turned of f (see page ).

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.
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.
In a crash, both stages
will ignite simultaneously to provide
the quickest and greatest protection.
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.
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.
Af ter inf lating, the f ront airbags
immediately def late, so they won’t
interf ere with the driver’s visibility,
or the ability to steer or operate
other controls.
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.

The driver’s advanced front airbag
system includes a seat position
sensor under the seat. If the seat is
too f ar f orward, the airbag will
inf late with less f orce, regardless of
the severity of the impact.
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 f ront 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 f ront.
For both advanced airbags to work
properly:
Occupants must sit upright and
wear their seat belts properly.
Back-seat passengers should not
put their f eet under the f ront seats.
Failure to f ollow these instructions
could damage the sensors or prevent
them f rom working properly. The passenger’s advanced f ront
airbag system has weight sensors
under the seat. Although Honda
does not encourage carrying an
inf ant or small child in f ront, 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
front airbag off.
Do not spill any liquids on or
under the seats, cover the sensors,
or put any objects or metal items
under the f ront seats.

To ensure that the passenger’s
advanced front airbag system will

This includes:
If the weight sensors detect there is
no passenger in the f ront seat, the
airbag will be off. However, the
passenger airbag of f indicator will
not come on.
When the airbag is turned of f , a
‘‘passenger airbag of f ’’ indicator in
the center of the dashboard comes

Be aware that objects placed on
the passenger’s seat can also
cause the airbag to be turned of f .
Moving the front seat or seat-back
f orcibly back against the f olded
rear seat.
If you ever have a moderate to
severe side impact, sensors will
detect rapid acceleration and signal
the control unit to instantly inf late
either the driver’s or the passenger’s
side airbag and activate the seat belt
tensioner on the af f ected side.

This indicator has two f unctions:Itcomesonwhenyouturnthe
ignition switch to the ON (II)
position. It is a reminder to check
the parking brake. A beeper
sounds if you drive with the
parking brake not f ully released.
Driving with the parking brake not
fully released can damage the
brakes and tires.
If it stays on after you have fully
released the parking brake while
the engine is running, or if it
comes on while driving, there
could be a problem with the brake
system. For more inf ormation, see
page . This indicator comes on brief ly when
you turn the ignition switch to the
ON (II) position. If it comes on at
any other time, it indicates a
potential problem with your f ront
airbags. This indicator will also alert
you to a potential problem with your
side airbags, passenger’s side airbag
cutof f system, side curtain airbags,
automatic seat belt tensioners,
driver’s seat position sensor, or the
f ront passenger’s weight sensors.

Your seat belt system includes lap/
shoulder belts in all f ive seating
positions. The f ront seat belts are
also equipped with automatic seat
belt tensioners.If the indicator comes on or the
beeper sounds when the driver’s seat
belt is latched and there is no f ront
seat passenger and no items on the
front seat, something may be
interf ering with the monitoring
system. Look f or and remove:
Any items under the f ront
passenger’s seat.
Any object(s) hanging on the seat
or in the seat-back pocket.
Any object(s) touching the rear of
the seat-back.
This system monitors the f ront 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.
This system uses the same sensors
as the front airbags to monitor
whether the f ront seat belts are
latched or unlatched, and how much
weight is on the f ront passenger’s
seat (see pages and ). If either the driver or a f ront
passenger does not f asten their seat
belt while driving, the beeper will
sound and the indicator will f lash
again at regular intervals.
If a f ront 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.
The seat belt system
includes an indicator on the
instrument panel and a beeper to
remind you and your passengers to
f asten your seat belts. When no one is sitting in the f ront
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 no obstructions are f ound, have
your vehicle checked by a dealer.
