Safe DrivingThe driver’s and passenger’s seats are
equipped with automatic seat belt tensioners
to enhance safety.
The tensioners automatically tighten the seat
belts during a moderate-to-severe frontal
collision, sometimes even if the collision is not
severe enough to inflate the front airbags or
the driver’s knee airbag.
■Automatic Seat Belt Tensioners1Automatic Seat Belt Tensioners
The seat belt tensioners can only operate once.
If a tensioner is activated, the SRS indicator will come
on. Have an authorized Ac ura NSX dealer replace the
tensioner and thoroughly insp ect the seat belt system
as it may not offer protecti on in a subsequent crash.
During a moderate-to-sev ere side impact, the
tensioner on that side of the vehicle also activates.

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

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.

uuChild Safety uSafety of Infants and Small Children
Safe DrivingSince this vehicle does not have a back seat, we recommend that you do not carry a
child, age 12 or under, as a passenger.
This is because placing a fo rward-facing child seat in the passenger’s seat can be
hazardous, even with advanced front airbags that automatically turn the
passenger’s front airbag off.
If you choose to ignore our warnings and transport a small child in this vehicle, be
sure to move the passenger seat as far to the rear as possi ble, and follow the
instructions and guidelines in the following pages.
■Protecting Smaller Children1 Protecting Smaller Children
Educate yourself about th e laws and regulations
regarding child seat use wh ere you are driving, and
follow the child seat manufacturer’s instructions.
A child seat must be secured to the vehicle with the
lap part of a lap/shoulder be lt. A child whose seat is
not properly secured to the vehicle can be
endangered in a crash.
3WARNING
Placing a forward-facing child seat in the
passenger’s seat can resu lt in serious injury
or death if the fron t airbag inflates.
If you must place a forward-facing child
seat in passenger’s seat, move the vehicle
seat as far back as possible, and properly
restrain the child.
