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 pages29and30).
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.
You will also see a
‘‘FASTEN SEAT
BELT ’’or ‘‘FASTEN PASSENGER
SEAT BELT ’’message on the multi-
information display (see page81).
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.

●Automatic front seat belt
tensioners (see page22).●Sensors that can detect a moderate
to severe front impact, side impact,
or if your vehicle is about to
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
page31).●Sensors that can detect whether
the driver's seat belt and the front
passenger's seat belt are latched or
unlatched (see page20).●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
29).
●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 page29).●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
page32).●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 page33).●An indicator on the instrument
panel that alerts you that the
passenger's side airbag has been
turned off (see page33).●An indicator on the dashboard that
alerts you that the passenger's
front airbag has been turned off
(see page34).●Emergency backup power in case
your vehicle's electrical system is
disconnected in a crash.

Advanced AirbagsYour front 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 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 objects or metal items
under the front seats.●Second-row passengers should not
put their feet 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 airbag is turned off, a
‘‘passenger airbag off ’’indicator in
the center of the dashboard comes
on (see page34).
If the weight sensors detect there is
no passenger in the front seat, the
airbag will be off. However, the
passenger airbag off indicator 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 second-row 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 passenger's seat
or seat-back forcibly back against
the folded right-side second-row
seat.
Also, make sure the floor mat behind
the front passenger's seat is hooked
to the floor mat anchor (see page
410).If it is not, the mat may
interfere with the proper operation of
the sensors and operation of the seat. How Your Side Airbags Work
If 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 and activate the seat belt
tensioner on the affected side.

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.

Airbag Service
Your airbag systems are virtually
maintenance free, and there are no
parts you can safely service.
However, you must have your
vehicle serviced if:●An airbag ever inflates.
Any airbag
that has deployed must be
replaced along with the control
unit and other related parts. Any
seat belt tensioner that activates
must also be replaced.
Do not try to remove or replace
any airbag by yourself. This must
be done by an authorized dealer or
a knowledgeable body shop.
●The SRS indicator alerts you to a
problem.
Take your vehicle to an
authorized dealer as soon as
possible. If you ignore this
indication, your airbags may not
operate properly.
●If your vehicle has a moderate to
severe impact.
Even if your airbags
do not inflate, your dealer should
inspect the driver's seat position
sensor, the front passenger's
weight sensors, the front seat belt
tensioners, and all seat belts and
their anchors worn during a crash
to make sure they are operating
properly. Additional Safety Precautions
●Do not attempt to deactivate your
airbags.
Together, airbags and seat
belts provide the best protection.
●Do not tamper with airbag components or wiring for any
reason.
Tampering could cause
the airbags to deploy, possibly
causing very serious injury.
●Do not expose the front
passenger's seat-back to liquid.
If
water or another liquid soaks into
a seat-back, it can prevent the side
airbag cutoff system from working
properly.

●Do not remove or modify a frontseat without consulting your
dealer.
This could make the
driver's seat position sensor or the
front passenger's weight sensors
ineffective. If it is necessary to
remove or modify a front seat to
accommodate a person with
disabilities, first contact Acura
Client Services at 800-382-2238.
●Do not cover or replace front seat- back covers without consulting
your dealer.
Improperly replacing
or covering front seat-back covers
can prevent your side airbags from
inflating during a side impact.
