2007 HONDA CIVIC SEDAN sensor

Your seat belt system includes lap/
shoulder belts in all five seating
positions. The front 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 front
seat passenger and no items on the
front seat, something may be
interfering with the monito ring
system. Look for and remove:
Any items under the front
passenger’s seat.
Any objects hanging on the seat or
in the seat-back pocket.
Any objects, such as a folded-down
back seat, that are touching the
rear of the seat-back.
If no obstru ctions are found, have
your vehicle checked by a dealer.
This system monitors the front seat
belts. If you turn the ignition switch
to the ON (II) position before your
seat belt is fastened, the beeper will
sound and the indicator will flash. If
your seat belt is not fastened before the
beeper stops, the indicator will
stop flashing 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.

airbag is stored in the center of
the steering wheel; the front

Two side airbags, one for the
driver and one for a front
passenger. The airbags are stored
in the outer edges of the seat-

Two side curtain airbags, one for
each side of the vehicle. The
airbags are stor ed in the ceiling,

After inflating, the front airbags
immediately deflate, so they won’t
interfere with the driver’s visibility,
or the ability to steer or operate
other controls.
Although
both airbags normally
inflate within a split second of each
other, it is possible for only one
airbag to deploy.
If you ever have a moderate to
severe frontal 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 front
passenger’s airbags, at the time and
with the force needed. This
can happen if the severity of a
collision is at the margin, or
threshold, that determines whether
or not the airb ags will deploy. In
such cases, the seat belt will provide
sufficient protection, and the
supplemental protection offered by
the airbag would be minimal.
The total time for inflation and
defl ation is one-tenth of a second, so
fast that most occupants are not
aware that the airbags deployed until
they see them lying in their laps.
Du
ring a frontal crash, your seat belt
restrains your lower body and torso,
and the front airbag helps protect
your head and chest.
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 ). 26

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.
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.
In a crash, 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. If the occupant’s belt is ,
the airbag will deploy at a slightly
lower threshold, because the
occupant would need extra
protection.
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.
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.

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.
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. 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.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.
