uuAirbags uAirbag System Components
Safe Driving
The front, driver’s knee, side, and side
curtain airbags are deployed according to
the direction and severity of impact. Both
side curtain airbags are deployed in a
rollover. The airbag system includes:
aTwo SRS (Supplemental Restraint System)
front airbags. The driver’s airbag is stored
in the center of the steering wheel; the
passenger’s airbag is stored in the
dashboard. Both are marked SRS
AIRBAG.
bDriver’s knee airbag. The knee airbag is
stored under the steering column. It is
marked SRS AIRBAG.
cTwo side airbags, one for the driver and
one for a passenger. The airbags are
stored in the outer edges of the seat-
backs. Both are marked SIDE AIRBAG .
dTwo 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.
eAn electronic control unit that, when the
power system is on, continually monitors
information about the various impact
sensors, seat and buckle sensors, rollover
sensor, airbag activators, seat belt
tensioners, and other vehicle
information. During a crash event the
unit records such information.
fAutomatic seat belt tensioners. In
addition, the driver’s and passenger’s
seat belt buckles incorporate sensors that
detect whether or not the belts are
fastened.
gWeight sensors in the passenger’s seat.
The passenger’s airbag will be turned off
if the weight on the seat is 65 lbs (29 kg)
or less (the weight of an infant or small
child).
hImpact sensors that can detect a
moderate-to-severe front or side impact.
iAn indicator on the dashboard that alerts
you that the passenger’s front airbag has
been turned off.
jAn indicator on the instrument panel that
alerts you to a possibl e problem with your
airbag system or seat belt tensioners.
kA rollover sensor that can detect if your
vehicle is about to roll over and signal the
control unit to deploy both side curtain
airbag.

uuAirbags uFront Airbags (SRS)
Safe DrivingFront airbags are designed to inflate duri ng moderate-to-severe frontal collisions.
When the vehicle decelerates suddenly, the sensors send information to the control
unit which signals one or both front airbags to inflate.
A frontal collision can be either head-on or angled between two vehicles, or when a
vehicle crashes into a stationary object, such as a concrete wall.
While your seat belt restrains your torso, the
front airbag provides supplemental protection
for your head and chest.
The front airbags deflate immediately so that
they won’t interfere with the driver’s visibility
or the ability to steer or operate other
controls.
The total time for inflation and deflation is so fast that most occupants are not
aware that the airbags deployed until th ey see them lying in front of them.
■Operation
■How the Front Airbags Work1How the Front Airbags Work
Although the driver’s a nd passenger’s airbags
normally inflate within a spli t 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 protec tion, and the supplemental
protection offered by the airbag would be minimal.

Safe Driving
■When front airbags should not deploy
Minor frontal crashes: Front airbags were designed to supplement seat belts and
help save lives, not to prevent minor scrapes, or even broken bones that might occur
during a less than moderate-to-severe frontal crash.
Side impacts: Front airbags can provide protection when a sudden deceleration
causes a driver or passenger to move towa rd the front of the vehicle. Side airbags
and side curtain airbags have been specifically designed to help reduce the severity
of injuries that can occur during a moderate-to-severe side impact which can cause
the driver or passenger to move toward the side of the vehicle.
Rear impacts: Head restraints and seat belts are your best protection during a rear
impact. Front airbags cannot provide any significant protection and are not designed
to deploy in such collisions.
Rollovers: Seat belts, and in vehicl es equipped with a rollover sensor, side curtain
airbags offer the best protection in a ro llover. Because front airbags could provide
little if any protection, they are not designed to deploy during a rollover.
■When front airbags deploy with little or no visible damage
Because the airbag system senses sudden deceleration, a strong impact to the
vehicle framework or suspension might caus e one or more of the airbags to deploy.
Examples include running into a curb, the edge of a hole, or other low fixed object
that causes a sudden deceleration in th e vehicle chassis. Since the impact is
underneath the vehicle, damage may not be readily apparent.
■When front airbags may not deploy, even though exterior damage
appears severe
Since crushable body parts absorb crash energy during an impact, the amount of
visible damage does not always indicate proper airbag operation. In fact, some
collisions can result in severe damage but no airbag deployment because the airbags
would not have been needed or would not have provided protection even if they
had deployed.

uuAirbags uFront Airbags (SRS)
Safe DrivingThe passenger’s airbag have advanced f eatures to help reduce the likelihood of
airbag related injuries to a smaller occupant. The passenger’s advanced front airbag system
has weight sensors.
Although we recommend against carrying an
infant or small child in the passenger seat, if
the sensors detect the weight of a child (up to
about 65 lbs or 29 kg), the system will
automatically turn off the passenger’s front
airbag.
■Advanced Airbags1 Advanced Airbags
For the passenger’s advanced front airbag to work
properly:
•Do not spill any liquid on or under the seat.
•Do not put any object under the passenger’s seat.•Make sure any objects are positioned properly on
the floor. Improperly pos itioned objects can
interfere with the advanced airbag sensors.
•An occupant should sit upright and wear their seat
belts properly.
•Do not place any cover over the passenger side
dashboard. 2 Passenger Airbag Off Indicator P. 56

uuAirbags uSide Airbags
Safe Driving
Side Airbags
The side airbags help protect the torso and pelvis of the driver or a passenger during
a moderate-to-severe side impact.
The side airbags are housed in the outside
edge of the driver’s and passenger’s seat-
backs.
Both are marked SIDE AIRBAG.
When the sensors detect a moderate-to-
severe side impact, the control unit signals the
side airbag on the impact side to immediately
inflate.
■Housing Locations
1 Side Airbags
Make sure you and your pa ssenger always sit upright.
Leaning into the path of a side airbag can prevent the
airbag from deploying properly and increases your
risk of serious injury.
Do not attach accessories on or near the side airbags.
They can interfere with the proper operation of the
airbags, or hurt someone if an airbag inflates.
Do not cover or replace th e seat-back covers without
consulting an authoriz ed Acura NSX dealer.
Improperly replacing or cove ring seat-back covers can
prevent your side airbag s from properly deploying
during a side impact.

uuAirbags uSide Airbags
Safe Driving
■When a side airbag deploys with little or no visible damage
Because the airbag system senses sudden acceleration, a strong impact to the side
of the vehicle’s framework can cause a side airbag to deploy. In such cases, there
may be little or no damage, but the side impact sensors detected a severe enough
impact to deploy the airbag.
■When a side airbag may not deploy, even though visible damage appears
severe
It is possible for a side airbag to not deploy during an impact that results in
apparently severe damage. This can occur when the point of impact was toward the
far front or rear of the vehicle, or when the vehicle’s crushable body parts absorbed
most of the crash energy. In either case , the side airbag would not have been
needed nor provided protection even if it had deployed.

Safe Driving■When the passen ger airbag off
indicator comes on
The indicator comes on to alert you that the
passenger’s front airbag has been turned off.
This occurs when the weight sensors detect
about 65 lbs (29 kg) or less, the weight of an
infant or small child, on the seat.
Your vehicle is not recommended for child passengers. Never put a rear-facing child
seat in this vehicle.
If you decided to disregard our recommendations and transport a small child, they
should be properly restrained.
2 Child Safety P. 58
Objects placed on the seat can also cause the indicator to come on.
If the passenger seat is empty, the passeng er’s front airbag will not deploy and the
indicator will not come on.
■Passenger Airbag Off Indicator1 Passenger Airbag Off Indicator
To ensure the passenger is detected properly,
confirm that:
•There is no object pressing against the rear of the
seat-back.
•The passenger’s seat or seat-back is not forced
back against the rear wall of the vehicle.
•There is no object placed under or beside the
passenger’s seat.
•The occupant is sitting in an upright position and
the seat back is not excessively reclined.
•The occupant is not leaning against the door or
center console.
•The occupant’s feet are placed on the floor in front
of them.
•There are no objects hanging from the passenger’s
seat.
The passenger airbag off indicator may come on and
go off periodically if the tota l weight on the seat is
near the airbag cutoff threshold.
Have your vehicle checked by an authorized Acura
NSX dealer as soon as possible if:
•All of the above conditions are met, and the
indicator comes on with an adult riding there.
•All of the above conditions are met, and the
indicator goes off with a small child riding there.
(See Child Safety.)
•If the seat is empty and the indicator is on.
Do not allow an adult passe nger to ride in the seat
when the indicator is on.
