sensor Acura TSX 2007 Owner's Manual

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
either the driver or a front
passenger does not fasten their seat
belt while driving, the beep er will
sound and the indicator will flash
again at regular intervals.
You will also see a ‘‘FAS TEN SEAT
BELT’’ or ‘‘FASTEN PASSENGER
SEAT BELT’’ message on the multi-
information display (see page ).
When no one is sitting in the front
passenger’s seat, or a child or small
adult is riding there, the indicator
should not come on and the beeper
should not sound.
The
seat belt system
includes an indicator on the
instrument panel and a beeper to
remind you and your passengers to
fasten your 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.
If a front passenger does not fasten
their seat belt, the indicator will
come on about 6 seconds after the
ignition switch is turned to the ON
(II) position.
This
system uses the same sensors
as the front airbags to monitor
whether the front seat belts are
latched or unlatched, and how much
weight is on the front passenger’s
seat (see pages and ). 78

Your airbag system includes:
Two side airbags, one for the
driver and one for a front
passenger. The airbags are stored
in the outer edges of the seat-
backs. Both are marked ‘‘SIDE
AIRBAG’’ (see page ).
Two
SRS (supplemental restraint
system) front airbags. The driver’s
airbag is stored in the center of
the steering wheel; the front
passenger’sairbagisstoredinthe
dashboard. Both are marked ‘‘SRS
AIRBAG’’ (see page ). Two
side curtain airbags, one for
each side of the vehicle. The
airb ags are stored in the ceiling,
above the side windows. The front
and rear pillars are marked ‘‘SIDE
CURTAIN AIRBAG’’ (see page
).
Sensors that can detect a
moderate to severe front impact or
side impact.
Automatic
front seat belt
tensioners (see page ). Sensors
that can detect whether
a child is in the passenger’s side
airbag path and signal the
control unit to turn the airbag
off (see page ).

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.
Al
though both airbags normally
inflate within a split second of each
other, it is possible for 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
sufficient protection, and the
supplemental protection offered by
the airbag would be minimal.
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
infl ate the driver’s and front
passenger’s airbags, at the time and
with the force needed. 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 ). 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.

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.
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.
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 deploy at a slightly
lower threshold, because the
occupant would need extra
protection.
If the occupant’s belt , 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.

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.
Do not spill any liquids on or
under the seats, cover the sensors,
or put any cargo or metal objects
under the f ront seats.
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 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.
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 Acura 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.

the front passenger’s seat is hooked
to the floor mat anchor (see page
). If it is not, the mat may
interfere with the proper operation
of the sensors and operation of the
seat.
To
ensure that the passenger’s
advanced front airbag system will
work properly,
This includes:
A rear passenger pushing or
pulling on the back of the front
passenger’s seat.
Moving the front seat forcibly
back against cargo on the seat or
floor behind it.
When
the airbag is turned off, a
‘‘passenger airbag off’’ indicator in
the center of the dashboard comes
on (see page ).
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. Be aware that objects placed on the
passenger’s seat can also cause the
airbag to be turned off.

Only one airbag will deploy during a
side impact. If the impact is on the
passenger’s side, the passenger’s
side airbag will deploy even if there
is no passenger.
To get the best protection f rom the
side airbags, front seat occupants
should wear their seat belts and sit
upright and well back in their seats.
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. Your vehicle has a side airbag cutoff
system designed primarily to protect
a child riding in the f ront passenger’s
seat.
Although Acura does not encourage
children to ride in f ront, if the
sensors in the seat detect a child has
leaned into the side airbag’s
deployment path, the airbag will shut
off.

short adult leans sideways, or a

If the impact is on the passenger’s
side, the passenger’s side curtain
airbag will inflate even if there are no
occupants on that side of the vehicle.
To get the best protection from the
side curtain airbags, occupants
should wear their seat belts and sit
upright and well back in their seats.
A front seat passenger should not
use a cushion or other object as a
backrest. It may prevent the cutoff
system from working properly.
There
will be some delay between
the moment the passenger moves
into or out of the airbag deployment
pathandwhentheindicatorcomes

on (see page ), have the
passenger sit upright. Once the
passenger is out of the airbag’s
deployment path, the system will
turn the airbag back on, and the
indicator will go out.
In a moderate to severe side impact,
sensors will detect rapid acceleration
and signal the control unit to
instantly inflate the side curtain
airbag and activate the seat belt
tensioner on the driver’s or the
passenger’s side of the vehicle.
