2. Insert the latch plate into the buckle, then
tug on the belt to make sure the buckle is secure.
uMake sure that the belt is not twisted or
caught on anything.
1Fastening a Seat Belt
No one should sit in a seat with an inoperative seat
belt or one that does not appear to be working
correctly. Using a seat be lt that is not working
properly may not protect the occupant in a crash.
Have an authorized Acura NSX dealer check the belt
as soon as possible.
Never insert any foreign obj ects into the buckle or
retractor mechanism.
If the seat belt appears to be locked in a fully
retracted position, firmly pull out on the shoulder belt once, then push it back in.
Then smoothly pull it out of the retractor and fasten.
If you are unable to release the seat belt from a fully
retracted position, do not al low anyone to sit in the
seat, and take your vehicle to a dealer for repair.

3. Position the lap part of the belt as low as
possible across your hips, then pull up on
the shoulder part of the belt so the lap part fits snugly. Th is lets your strong pelvic
bones take the force of a crash and reduces the chance of internal injuries.
4. If necessary, pull up on the belt again to
remove any slack, then check that the belt
rests across the center of your chest and
over your shoulder. Th is spreads the forces
of a crash over the strongest bones in your
upper body.1Fastening a Seat Belt
To release the belt, push the red PRESS button and
then guide the belt by hand until it has retracted
completely.When exiting the vehicle, be sure the belt is properly
stowed so that it will not get caught in the closing door.

driving or riding in a vehicle is to always wear a seat belt and keep the lap part of the
belt as low as possible across the hips.
■Advice for Pregnant Women1Advice for Pregnant Women
Each time you have a checkup, ask your doctor if it is
okay for you to drive.
To reduce the risk of inju ries to both you and your
unborn child that can be caus ed by an inflating front
airbag: • When driving, sit upright a nd adjust the seat as far
back as possible while allowing full control of the
vehicle.
• When sitting in the passenger’s seat, adjust the
seat as far back as possible.
Wear the shoulder belt
across the chest avoiding
the abdomen.

Safe Driving
Seat Belt Inspection
Regularly check the condition of your seat belts as follows: •Pull each belt out fully, and look for frays, cuts, burns, and wear.
• Check that the latch plates and buckles work smoothly and the belts retract easily.
uIf a belt does not retract eas ily, cleaning the belt may correct the problem. Only
use a mild soap and warm water. Do not use bleach or cleaning solvents. Make
sure the belt is completely dry before allowing it to retract.
Any belt that is not in good condition or working properly will not provide proper
protection and should be replaced as soon as possible.
A belt that has been worn during a crash may not provide the same level of
protection in a subsequent crash. Have your seat belts inspected by an authorized
Acura NSX dealer after any collision.

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 can record 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

uuAirbagsuAirbag System Components
Safe DrivingAirbags can pose serious hazards. To do their job, airbags must inflate with
tremendous force. So, while airbags help to save lives, they can cause burns, bruises,
and other minor injuries, sometimes even fatal ones if occupants are not wearing
their seat belts properl y and sitting correctly.
What you should do: Always wear your seat belt properly, and sit upright and as
far back from the steering wheel as possi ble while allowing full control of the
vehicle. A passenger should move their seat as far back from the dashboard as
possible.
Remember, however, that no safety system ca n prevent all injuries or deaths that
can occur in a severe crash, even when s eat belts are properly worn and the airbags
deploy.
Do not place hard or sharp objects between yourself and a front airbag.
Carrying hard or sharp objects on your lap, or driving with a pipe or other sharp
object in your mouth, can result in in juries if your front airbag inflates.
Do not attach or place objects on the front and driver

Types of Airbags
Your vehicle is equipped with four types of airbags: •Front airbags: Airbags in front of the driv er’s and passenger’s seats.
• Driver

Continued47
uuAirbagsuFront Airbags (SRS)
Safe DrivingFront airbags are designed to inflate during 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 and 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.

uuAirbagsuFront Airbags (SRS)
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 scrape s, 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 si gnificant protection and are not designed
to deploy in such collisions.
Rollovers: In a rollover, your best form of protection is a seat belt or, if your vehicle
is equipped with a rollover sensor, both a se at belt and a side curtain airbag. Front
airbags, however, are not designed to deploy in a rollover as they would provide
little if any protection.
■ 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.
