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 and, on models with
collision mitigation brake system
(CMBS), seat belt e-pretensioners. 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.
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.
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. If
either the driver or a front
passenger does not fasten their seat
belt, the beeper 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.
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 ). 31 32 79

The e-pretensioners do not activate
when the seat belts are not worn or
when the vehicle stability assist
(VSA) off indicator on the
instrument panel is on.
For added safety, the front seat belts
are equipped with e-pretensioners
that work in combination with the
collision mitigation brake system
(CMBS) (see page ) and the
brake pedal assist function (see page
). If
your vehicle gets too close to the
vehicle ahead of it in your lane, the
driver’s e-pretensioner slightly
retracts the seat belt to alert the
driver of the approaching vehicle. If
a collision with the vehicle in front of
you is likely, the e-pretensioners on
both front seats retract the seat belts
with enough force to properly
restrain you and your front
passenger. After they activate, the
e-pretensioners release the retracted
seat belts.
To get the full benefit of the
e-pretensioners, you and your front
passenger must sit normally in your
seats and wear your seat belts
properly (see page ). In
addition, the front passenger’s
e-pretensioner does not activate
when the passenger’s airbag is
automatically turned off because the
weight sensor detects a child in the
front passenger’s seat.
If
the automatic seat belt tensioners
are activated by a collision, both
front seat belts and all related
components must be
replaced (see page ). If only the
e-pretensioners were activated, no
components need to be replaced.

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 side curtain airbags, one for
each side of the vehicle. The
airbags are stored in the ceiling,
above the side windows. The front
and rear pillars are marked ‘‘SIDE
CURTAIN 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 ).

Sensors
that can detect whether
the driver’s seat belt and a front

After inflating, the front airbags will
immediately deflate, so they won’t
interfere with the driver’s visibility,
or the ability to steer or operate
other controls.
The total time for inflation and
deflation 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.
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 f orce 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 ).

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.
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.
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.

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 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.
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.
Be aware that objects placed on the
passenger’s seat can also cause the
airbag to be turned off.
