The most important things you need
to know about your airbags are:●Airbags do not replace seat belts.They are designed to supplement
the seat belts.●Airbags offer no protection in rearimpacts, or minor frontal or sidecollisions.●Airbags can pose serious hazards.To do their job, airbags must
inflate with tremendous force. So
while airbags help save lives, they
can cause minor injuries or more
serious or even fatal injuries if
occupants are not properly
restrained or sitting properly.
What you should do:
Always wear
your seat belt properly, and sit
upright and as far back from the
steering wheel as possible while
allowing full control of the vehicle. A
front passenger should move their
seat as far back from the dashboard
as possible. The rest of this section gives more
detailed information about how you
can maximize your safety.
Remember, however, that no safety
system can prevent all injuries or
deaths that can occur in a severe
crash, even when seat belts are
properly worn and the airbags
deploy.

6. Maintain a Proper SittingPosition
After all occupants have adjusted
their seats and head restraints, and
put on their seat belts, it is very
important that they continue to sit
upright, well back in their seats, with
their feet on the floor, until the
vehicle is parked and the engine is
off.
Sitting improperly can increase the
chance of injury during a crash. For
example, if an occupant slouches, lies
down, turns sideways, sits forward,
leans forward or sideways, or puts
one or both feet up, the chance of
injury during a crash is greatly
increased. In addition, an occupant who is out of
position in the front seat can be
seriously or fatally injured in a crash
by striking interior parts of the
vehicle or being struck by an
inflating front airbag.
Sitting improperly or out of
position can result in serious
injury or death in a crash.
Always sit upright, well back in
the seat, with your feet on the
floor.

●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.

How Your Front Airbags WorkIf 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
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 can deploy if
there is no passenger in the front
seat, or if the advanced airbag
system has turned the passenger's
airbag off (see page34).
After inflating, the front airbags
immediately deflate, so they won't
interfere with the driver's visibility,
or the ability to steer or operate other
controls.

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.

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 page33),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.
