Your seat belt system includes lap/
shoulder belts in all seating positions.
The f ront seat belts are also
equipped with automatic seat belt
tensioners.
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 ).
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. 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.
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.
You will also see a ‘‘FASTEN SEAT
BELT’’ message on the multi-
inf ormation display. 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.
Models equipped with the
keyless access system have an
engine start/stop button instead
of an ignition switch. ON Mode
is the equivalent of ON (II). For
more inf ormation, see pagesand .
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. You will also see a ‘‘FASTEN SEAT
BELT’’ or ‘‘FASTEN PASSENGER
SEAT BELT’’ message on the multi-
inf ormation display.

Automatic front seat belt
tensioners (see page ).
Sensors that can detect a
moderate to severe front impact or
side impact.
Sensors that can detect whether a
child is in the passenger’s side
airbag path and signal the control
unit to turn the airbag of f (see
page ).
Your airbag system includes:
Two side airbags, one f or the
driver and one f or a f ront
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) f ront airbags. The driver’s
airbag is stored in the center of
the steering wheel; the f ront
passenger’sairbagisstoredinthe
dashboard. Both are marked ‘‘SRS
AIRBAG’’ (see page ).
Two side curtain airbags, one f or
each side of the vehicle. The
airbags are stored in the ceiling,
above the side windows. The f ront
and rear pillars are marked ‘‘SIDE
CURTAIN AIRBAG’’ (see page ). Sensors that can detect whether
the driver’s seat belt and the f ront
passenger’s seat belt are latched
or unlatched (see page ). A driver’s seat position sensor that
monitors the distance of the seat
from the front airbag. If the seat is
too f ar f orward, the airbag will
inf late with less f orce (see page
).
Weight sensors that monitor the
weight on the f ront 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 f ront airbag will be
turned of f (see page ).

ÎIf 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 inf late
the driver’s and f ront passenger’s
airbags, at the time and with the
f orce needed.
An indicator on the dashboard that
alerts you that the passenger’s

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 f ront

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 or small-statured adults who
ride in f ront.
For both advanced airbags to work
properly:
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.
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. 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. 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.

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.Be aware that objects placed on the
passenger’s seat can also cause the
airbag to be turned off.
When the passenger airbag gets
turned of f by the weight sensors, a
‘‘passenger airbag of f ’’ 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 is automatically turned off.
However, the passenger airbag of f
indicator in this situation will not
come on.
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. 34

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 f ront
passenger’s seat.
Moving the front seat or seat-back
forcibly back against cargo on the
seat or f loor behind it.
Hanging heavy items on the f ront
passenger seat, or placing heavy
items in the seat-back pocket. 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.
Also,makesurethefloormat
behind the f ront passenger’s seat
is hooked to the f loor mat anchor
(see page ). If it is not, the mat
may interfere with the proper
operation of the sensors and
operation of the seat. Back seat passengers should not
wedge objects or intentionally
f orce their f eet under the f ront
passenger seat.

There will be some delay between
the moment the passenger moves
into or out of the airbag deployment
pathandwhentheindicatorcomes
on or goes of f .
A f ront seat passenger should not
use a cushion or another object as a
backrest. It may prevent the cutof f
system f rom working properly.
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.
Thesideairbagmayalsoshutoff if a
short adult leans sideways, or a
larger adult slouches and leans
sideways into the airbag’s
deployment path.
Objects placed on the f ront
passenger seat can also cause the
side airbag to be shut of f . Your vehicle has a side airbag cutof f
system designed primarily to protect
a child riding in the f ront passenger’s
seat.If the side airbag of f indicator comes
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.
Although Acura does not encourage
children to ride in f ront, if the
position sensors detect a child has
leaned into the side airbag’s
deployment path, the airbag will shut
off. 33
