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 ).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.
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.
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.
In addition to the seat belt reminder
indicator in the instrument panel,
you will also see a ‘‘FASTEN SEAT
BELT’’ or ‘‘FASTEN PASSENGER
SEAT BELT’’ message. This remains
displayed if you ignore it and do not
f asten the seat belt while driving.
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.

The tensioners can also be activated
during a collision in which the f ront
airbags . In this case, the
airbags would not be needed, but the
additional restraint could be helpf ul.
When the tensioners are activated,
the seat belts will remain tight until
they are unbuckled.
The tensioners are designed to
activate in any collision severe
enough to cause the f ront airbags to
deploy, or if a sensor detects your
vehicle is about to roll over (see page).
For added protection, the f ront seat
belts are equipped with automatic
seat belt tensioners. When activated,
the tensioners immediately tighten
the belts to help hold the driver and
a f ront passenger in position.
If the shoulder part of the belt is
pulled all the way out, the lockable
retractor will activate. The belt will
retract, but it will not allow the
passenger to move f reely.
To deactivate the lockable retractor,
unlatch the buckle and let the seat
belt fully retract. To refasten the
seat belt, pull it out only as f ar as
needed.
If a side curtain airbag deploys
during a side impact, the tensioner
on that side of the vehicle will also
deploy.30

Your airbag system includes: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 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 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 ). Automatic front seat belt
tensioners (see page ).
Sensors that can detect a
moderate to severe front impact,
side impact, or rollover.
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 ).
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 ).
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
passenger seat belt use when the
ignition switch is in the ON (II)
position.
A rollover sensor that can detect if
your vehicle is about to roll over
and signal the control unit to
deploy both side curtain airbags
and f ront seat belt tensioners (see

(see page ).
An indicator on the instrument
panel that alerts you that the
passenger’s side airbag has been
turned of f (see page ).
An indicator on the dashboard that
alerts you that the passenger’s

Emergency backup power in case
your vehicle’s electrical system is
disconnected in a crash.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. During a frontal crash, your seat belt
restrains your lower body and torso,
and the f ront airbag helps protect
your head and chest.
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 ).
Although both airbags normally
inf late within a split second of each
other, it is possible f or only one
airbag to deploy.

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.
For both advanced airbags to work
properly:
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.
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.
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.

Be aware that objects placed on the
passenger’s seat can also cause the
airbag to be turned off.
When the airbag is turned of f , 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 will be off. However, the
passenger airbag of f indicator will
not come on.
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. 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 f ront seat f orcibly
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.
Moving the front seat or seat-back

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.Your vehicle has a side airbag cutof f

a child riding in the f ront passenger’s
seat.

short adult leans sideways, or a
larger adult slouches and leans
sideways into the airbag’s

Objects placed on the f ront
passenger seat can also cause the
side airbag to be shut off.
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
of f .
If you ever have a moderate to
severe side impact, sensors will
detect rapid acceleration and signal
the control unit to instantly inf late

To get the best protection f rom the
side curtain airbags, occupants
should wear their seat belts and sit
upright and well back in their seats.
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.
If the rollover sensor detects your
vehicle is about to roll over, it signals
the control unit, which immediately
deploys both side curtain airbags and
activates both f ront seat belt
tensioners.
The airbag on the passenger’s side
will deploy, and the seat belt
tensioner will activate, even if there
are no passengers on that side of the
vehicle.
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.
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.
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 other object as a
backrest. It may prevent the cutof f
