Safe Driving
Driver’s Knee Airbag
The driver’s knee SRS airbag in flates in a moderate to severe frontal collision to help
keep the driver in the proper position and to help to maximize the benefit provided
by the vehicle’s other safety features.
SRS (Supplemental Restraint System) indica tes that the airbag is designed to
supplement seat belts, not replace them. Seat belts are the occupant’s primary
restraint system.
The driver’s knee airbag is housed under the
steering column.
The airbag is marked SRS AIRBAG.
When the driver’s front airbag inflates, the
driver’s knee airbag also inflates.
Even if the collision is not severe enough to
deploy the front airbag, the knee airbag may
inflate alone.
■Housing Locations
1 Driver’s Knee Airbag
Do not attach accessories on or near the driver’s knee
airbag. They can interfere with the proper operation
of the airbag, or hurt someone if an airbag inflates.

uuAirbags uDriver’s Knee Airbag
Safe Driving
■When driver’s knee airbag deploy s with little or no visible damage
Because the airbag system senses sudden deceleration, a strong impact to the
vehicle framework or suspension might cause 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 driver’s knee airbag may not de ploy, 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 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 pr operly 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 authorized 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.

uuAirbags uSide Curtain Airbags
Safe Driving
Side Curtain Airbags
The side curtain airbags help protect the heads of the driver and any passengers
during a moderate-to-severe side impact. The side curtain airbags equipped in this
vehicle are also designed to help reduce the likelihood of partial and complete
ejection of vehicle occupants through side windows in crashes, particularly rollover
crashes.
The side curtain airbags are located in the
ceiling above the side windows on both sides
of the vehicle.
The side curtain airbag is designed to deploy
in a rollover or a moderate-to-severe side
impact.
■Housing Locations
1Side Curtain Airbags
If the SRS control unit sens es that your vehicle is
about to rollover, it imme diately deploys both side
curtain airbags and activates both seat belt
tensioners.
If the impact is on the passenger’s side, the
passenger’s side curtain airbag deploys even if there
is no occupant on that side of the vehicle.
To get the best protecti on from the side curtain
airbags, occupants should wear their seat belts
properly and sit upr ight and well back in their seats.
Do not attach any objects to the side windows or roof
pillars as they can interfere with the proper operation
of the side curtain airbags.

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 plac ed 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

Airbag Care
You do not need to, and should not, perform any maintenance on or replace any
airbag system components yourself. However, you should have your vehicle
inspected by an authoriz ed Acura NSX dealer in the following situations:
■When the airbags have deployed
If an airbag has inflated, th e control unit and other related parts must be replaced.
Similarly, once an automatic seat belt te nsioner has been activated, it must be
replaced.
■When the vehicle has been in a moderate-to-severe collision
Even if the airbags did not in flate, have an authorized Acura NSX dealer inspect the
following: the weight sensors in the passenge r’s seat, seat belt tensioners, and each
seat belt that was worn during the crash.
■Do not remove or modify a seat with out consulting an authorized Acura
NSX dealer
This would likely disable or affect the prope r operation of the weight sensors in the
passenger’s seat. If it is necessary to re move or modify a seat to accommodate a
person with disabilities, contact an authoriz ed Acura NSX dealer, or for U.S. vehicles,
Acura Client Service at 1-844-682-2872 and for Canadian vehicles, Acura Client
Service at 1-888-9-ACURA-9 or 1-844-9-MYNSX-9 (NSX-specific).
1 Airbag Care
We recommend against the use of salvaged airbag
system components, including the airbag, tensioners,
sensors, and control unit.

Child Safety
Protecting Child Passengers
Each year, many children are injured or killed in vehicle crashes because they are
either unrestrained or not properly res trained. In fact, vehicle crashes are the
number one cause of death of children ages 12 and under.
To reduce the number of child deaths and in juries, every state, Canadian province
and territory requires that children be prope rly restrained when they ride in a vehicle.
Since 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:
• An inflating front or side ai rbag can injure or kill a child sitting in the passenger’s
seat.
• A child in the passenger’s seat is more likel y to interfere with the driver’s ability to
safely control the vehicle.
• Statistics show that children of all sizes and ages are safer when they are properly
restrained in a rear seat. Because this vehicle does not have a rear seat, we
recommend that you do not carry a child age 12 or under in this vehicle.1 Protecting Child Passengers
The National Highway Traffic Safety Administration
and Transport Canada recommend that all children
ages 12 and under be properl y restrained in a rear
seat. Some states or provin ces/territories have laws
restricting where ch ildren may ride.
Never put a rear-facing child seat in this vehicle.
3WARNING
Children who are unrestrained or
improperly restrained can be seriously
injured or killed in a crash.
Any child too small for a seat belt should be
properly restrained in a child seat. A larger
child should be properly restrained with a
seat belt, using a booster seat if necessary.

uuChild Safety uProtecting Child Passengers
Safe Driving
• Any child who is too small to wear a seat belt correctly must be restrained in an
approved child seat that is properly secured to the vehicle using the lap belt
portion of the lap/shoulder belt.
• Never hold a child on your lap because it is impossible to protect them in the
event of a collision.
• Never put a seat belt over yourself and a child. During a crash, the belt would
likely press deep into the child and cause serious or fatal injuries.
• Never let two children use the same seat belt. Both children could be very
seriously injured in a crash.
• Do not allow children to operate the doors, windows or seat adjustments.
• Do not leave children in the vehicle unatte nded, especially in hot weather when
the inside of the vehicle can get hot enough to kill them. They could also activate
vehicle controls causing it to move unexpectedly.1 Protecting Child Passengers
To deactivate a lockable retractor, release the buckle
and allow the seat belt to wind up all the way.
To remind you of the pa ssenger’s front airbag
hazards and child safety, your vehicle has warning
labels on the dashboard (U.S. models) and on the
front visors. Please read and follow the instructions
on these labels. 2 Safety Labels P. 68
3WARNING
Allowing a child to play with a seat belt or
wrap one around their neck can result in
serious injury or death.
Instruct children not to play with any seat
belt.
