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 and fr ont 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.

■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 front passenger to move toward the front of the vehicle. Side
airbags and side curtain airb ags 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: 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.

uuAirbags uFront Airbags (SRS)
Safe DrivingThe airbags have advanced features to he lp reduce the likelihood of airbag related
injuries to smaller occupants. The driver’s advanced airbag system includes a
seat position sensor.
Based on information from this sensor and the
severity of the impact, the advanced airbag
system determines the optimal deployment of
the driver’s airbag.
The front passenger’s ad vanced airbag system
has weight sensors.
We advise against allowi ng a child age 12 or
under to ride in the front passenger’s seat.
However, if you do allow a child age 12 or
under to ride in the front passenger’s
seat , note that the system will automatically
turn off the front passenger’s airbag if the
sensors detect that the child is approximately
65 lbs (29 kg) or less.
■Advanced Airbags1 Advanced Airbags
If there is a problem with the driver’s seat position
sensor, the SRS indicator wi ll come on, and in the
event of a crash, the airbag will deploy (regardless of
the driver’s seating position) with a force
corresponding to the se verity of the impact.
For the advanced airbags to work properly:
•Do not spill any liquid on or under the seats.
•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.
•All occupants should sit upri ght and wear their seat
belts properly.
•Do not cover the passenger ’s side dashboard with
a cloth, towel, cover, etc. 2Passenger Front Airbag Off Indicator

uuAirbags uDriver’s Knee Airbag
Safe Driving
Driver’s Knee Airbag
The driver’s knee SRS airbag inflates in a moderate-to-severe fronta l collision to help
keep the driver in the proper position and to help 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.
■Housing Locations
1 Driver’s Knee Airbag
Do not attach accessories on or near a knee airbag as
they can interfere with the proper operation of the
airbag, or even hurt someone if the airbag inflates.
The driver should not stor e any items under the seat
or behind their feet. The items can interfere with
proper airbag deployment in the event of a moderate
to sever frontal collision a nd may result in inadequate
protection.

Safe Driving
Side Curtain Airbags
The side curtain airbags help protect the heads of the driver and passengers in the
outer seating positions 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 front seat belt
tensioners.
If the impact is on the passenger’s side, the
passenger’s side curtain airbag deploys even if there
are no occupants 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.

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 a dealer in the following situations:
■When the airbags have deployed
If an airbag has inflated, the 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 infl ate, have your dealer inspect the following: the driver’s
seat position sensor, weight sensors in the passenger’s seat, front seat belt
tensioners, and each seat belt that was worn during the crash.
■Do not remove or modi fy a front seat without consulting a dealer
This would likely disable or affect the proper operation of the driver’s seat position
sensor or the weight sensors in the passenge r’s seat. If it is necessary to remove or
modify a front seat to accommodate a pe rson with disabilities, contact an Acura
dealer, or for U.S. vehicles, Acura Clie nt Relations at 1-800-382-2238 and for
Canadian vehicles, Acura Client Services at 1-888-9-ACURA-9.
1Airbag 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 infants and childre n be properly restrained when they ride
in a vehicle.
Children should sit properly restrained in a rear seat. This is because:
• An inflating front or side airbag can injure
or kill a child sitti ng in the front seat.
• A child in the front seat is more likely to
interfere with the driver ’s ability to safely
control the vehicle.
• Statistics show that ch ildren of all sizes and
ages are safer when they are properly
restrained in a rear seat.1 Protecting Child Passengers
The National Highway Traffic Safety Administration
and Transport Canada reco mmend 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.
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.
