Seat Belt System Components
Your seat belt system includes lap/
shoulder belts in all seating
positions. The front seat belts are
also equipped with automatic seat
belt tensioners.
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 pages28and 29).
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 while driving, the beeper will
sound and the indicator will flash
again at regular intervals.
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
fasten the seat belt while driving.
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.

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 freely.
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 far as needed.Automatic Seat Belt Tensioners
For added protection, the front seat
belts are equipped with automatic
seat belt tensioners. When activated,
the tensioners immediately tighten
the belts to help hold the driver and a
front passenger in position.The tensioners are designed to
activate in any collision severe
enough to cause the front airbags to
deploy, or if a sensor detects your
vehicle is about to roll over (see page
31).
If a side curtain airbag deploys
during a side impact, the tensioner
on that side of the vehicle will also
deploy.
The tensioners can also be activated
during a collision in which the front
airbags
do not deploy.
In this case, the
airbags would not be needed, but the
extra tension in the seat belt could be
helpful.
When the tensioners are activated,
the seat belts will remain tight until
they are unbuckled.

Your airbag system includes:●Two SRS (supplemental restraint
system) front airbags. The driver's
airbag is stored in the center of the
steering wheel; the front
passenger's airbag is stored in the
dashboard. Both are marked‘‘SRS
AIRBAG ’’(see page 26).●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 30).●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 31).
●Automatic front seat belt
tensioners (see page 22).●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 off (see
page30).●Sensors that can detect whether
the driver's seat belt and the front
passenger's seat belt are latched or
unlatched (see page 20).●A driver's seat position sensor that
monitors the distance of the seat
from the front airbag. If the seat is
too far forward, the airbag will
inflate with less force (see page
28).
●Weight sensors that monitor the
weight on the front passenger's
seat. If the weight is about 65 lbs
(29 kg) or less (the weight of an
infant or small child), the
passenger's front airbag will be
turned off (see page28).●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 front seat belt tensioners (see
page31).●A sophisticated electronic system
that continually monitors and
records information about the
sensors, the control unit, the
airbag activators, the seat belt
tensioners, and driver and front
passenger seat belt use when the
ignition switch is in the ON (II)
position.

●An indicator on the instrument
panel that alerts you to a possible
problem with your airbags,
sensors, or seat belt tensioners
(see page32).●An indicator on the instrument
panel that alerts you that the
passenger's side airbag has been
turned off (see page 32).●An indicator on the dashboard that
alerts you that the passenger's
front airbag has been turned off
(see page33).●Emergency backup power in case
your vehicle's electrical system is
disconnected in a crash. How Your Front Airbags Work
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 inflate
the driver's and front passenger's
airbags, at the time and with the
force needed. During a frontal crash, your seat belt
restrains your lower body and torso,
and the front airbag helps protect
your head and chest.
Although 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.
Only the driver's airbag will deploy if
there is no passenger in the front
seat, or if the advanced airbag
system has turned the passenger's
airbag off (see page
33).

Dual-Threshold AirbagsYour front airbags are also dual-
threshold airbags. Airbags with this
feature 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
not latched,
the airbag will deploy at a slightly
lower threshold, because the
occupant would need extra
protection.
If the occupant's belt is
latched,
the
airbag will inflate at a slightly higher
threshold, when the airbag would be
needed to supplement the protection
provided by the seat belt.
Advanced AirbagsYour front airbags are also advanced
airbags. The main purpose of this
feature is to help prevent airbag-
caused injuries to children or small
statured adults who ride in front.
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 front seats.
Failure to follow these instructions
could damage the sensors or prevent
them from 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 inflate
with less force, 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 inflate in the normal
manner regardless of the driver's
seating position.

The passenger's advanced front
airbag system has weight sensors
under the seat. Although Acura does
not encourage carrying an infant or
small child in front, if the sensors
detect the weight of an infant 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 off by the weight sensors, a
‘‘
passenger airbag off ’’indicator in
the center of the dashboard comes
on (see page 33).
If the weight sensors detect there is
no passenger in the front seat, the
airbag is automatically turned off.
However, the passenger airbag off
indicator in this situation will not
come on.
To ensure that the passenger's
advanced front airbag system will
work properly,
do not do anything
that would increase or decrease the
weight on the front passenger's seat.
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.●Hanging heavy items on the front
passenger seat, or placing heavy
items in the seat-back pocket.●Moving the front seat or seat-back
forcibly back against the folded
rear seat.●Back seat passengers should not
wedge objects or intentionally
force their feet under the front
passenger seat.
Also, make sure the floor mat
behind the front passenger's seat
is properly positioned on the floor
(see page 438). If it is not, the mat
may interfere with the proper
operation of the front passenger's
seat and its sensors.

How Your Side Airbags WorkIf you ever have a moderate to severe
side impact, sensors will detect rapid
acceleration and signal the control
unit to instantly inflate either the
driver's or the passenger's side
airbag.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 from the
side airbags, front seat occupants
should wear their seat belts and sit
upright and well back in their seats.
Side Airbag Cutoff SystemYour vehicle has a side airbag cutoff
system designed primarily to protect
a child riding in the front passenger's
seat.
Although Acura does not encourage
children to ride in front, if the
position sensors detect a child has
leaned into the side airbag's
deployment path, the airbag will shut
off.
The side airbag may also shut off if a
short adult leans sideways, or a
larger adult slouches and leans
sideways into the airbag's
deployment path.
Objects placed on the front
passenger seat can also cause the
side airbag to be shut off.

If the side airbag off indicator comes
on (see page32), 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
path and when the indicator comes
on or goes off.
A front seat passenger should not
use a cushion or other object as a
backrest. It may prevent the cutoff
system from working properly. How Your Side Curtain Airbags
Work
In a Side ImpactIn 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 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.
In a RolloverIf 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 front 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.
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.

How the Passenger Airbag Off
Indicator WorksThis indicator alerts you that the
passenger's front airbag has been
shut off because weight sensors
detect about 65 lbs (29 kg) or less
(the weight of an infant or small
child) on the front passenger's seat.
It does
not mean
there is a problem
with the airbag. Be aware that objects placed on the
front seat can cause the indicator to
come on.
If no weight is detected on the front
seat, the airbag will be automatically
shut off. However, the indicator will
not come on.
The passenger airbag off indicator
may come on and off repeatedly if the
total weight on the seat is near the
airbag cutoff threshold.
If an adult or teenage passenger is
riding in front, move the seat as far to
the rear as possible, and have the
passenger sit upright and wear the
seat belt properly.
If the indicator comes on with no
front seat passenger and no objects
on the seat, or with an adult riding
there, something may be interfering
with the weight sensors. Look for
and remove:
●Any items under the front
passenger's seat.●Any object(s) hanging on the seat
or in the seat-back pocket.●Any object(s), such as a folded-
down back seat, that are touching
the rear of the seat-back.
If no obstructions are found, have
your vehicle checked by a dealer as
soon as possible.
