About Your Seat Belts
28Safe Driving
Automatic Seat Belt Tensioners
The front seats are equipped with automatic seat belt tensioners to enhance
safety.
The tensioners automatically tighten the front seat belts during a moderate-to-
severe frontal collision, sometimes even if the collision is not severe enough to
inflate the front airbags.
Automatic Seat Belt Tensioners
The seat belt tensioners can only operate once.
If a tensioner is activated, the SRS indicator will
come on. Have a dealer replace the tensioner and
thoroughly inspect the seat belt system as it may
not offer protection in a subsequent crash.
During a moderate-to-severe side impact, the
tensioner on that side of the vehicle also activates.

Advice for Pregnant Women
If you are pregnant, the best way to protect yourself and your unborn child when
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 Women
Each time you have a checkup, ask your doctor if it
is okay for you to drive.
To reduce the risk of injuries to both you and your
unborn child that can be caused by an inflating
front airbag:
When driving, sit upright and adjust the seat as tfar back as possible while allowing full control of
the vehicle.
When sitting in the front passenger's seat, adjust tthe seat as far back as possible.
Wear the shoulder belt

The front, front side, and side curtain
airbags are deployed according to the
direction and severity of impact. The airbag
system includes:
Two SRS (Supplemental Restraint
System) front airbags. The driver's airbag
is stored in the center of the steering
wheel; the front passenger's airbag
is stored in the dashboard. Both are
marked "SRS AIRBAG". Two side airbags, one for the driver and
one for a front passenger. The airbags
are stored in the outer edges of the
seat-backs. Both are marked "SIDE

Important Facts About Your Airbags
Airbags can pose serious hazards. To do their job, airbags must inflate with
tremendous force. So, while airbags help save lives, they can cause minor injuries,
sometimes even fatal ones if occupants are not properly wearing their seat belts
properly 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 possible while allowing full control of the
vehicle. A front passenger should move their seat as far back from the dashboard
as possible.

Remember, however, that no safety system can prevent all injuries or deaths
that can occur in a severe crash, even when seat 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 injuries if your front airbag inflates.
Do not attach or place objects on the front airbag covers. Objects on the
covers marked ”SRS AIRBAG” could interfere with the proper operation of the
airbags or be propelled inside the vehicle and hurt someone if the airbags inflate.
Important facts about your airbags
Do not attempt to deactivate your airbags.
Together, airbags and seat belts provide the best
protection.
When driving, keep hands and arms out of the
deployment path of the front airbag by holding
each side of the steering wheel. Do not cross an
arm over the airbag cover.

Types of Airbags
36Safe Driving
Front Airbags (SRS)The front SRS airbags inflate in a moderate to severe frontal collision to help protect
the head and chest of the driver and/or front passenger.
SRS (Supplemental Restraint System) indicates that the airbags are designed to
supplement seat belts, not replace them. Seat belts are the occupant's primary
restraint system.
Housing Locations
The front airbags are housed in the center of the steering wheel for the driver, and
in the dashboard for the front passenger. Both airbags are marked SRS AIRBAG. Types of AirbagsYour vehicle is equipped with three types of airbags:
Front airbags: tAirbags in front of the driver's and front passenger's seats.
Side airbags: t Airbags in the driver's and front passenger's seat-backs.
Side curtain airbags: tAirbags above the side windows.
Each is discussed in the following pages.
Types of Airbags
The airbags can inflate whenever the ignition switch
is in ON
II.
Front Airbags (SRS)
Dual-Stage, Multiple-Threshold Front Airbags
(SRS)
Your vehicle is equipped with dual-stage, multiple-
threshold front airbags (SRS).
During a frontal crash severe enough to cause
one or both front airbags to deploy, the airbags
can inflate at different rates, depending on the
severity of the crash, whether or not the seat belts
are latched, and/or other factors. Frontal airbags
are designed to supplement the seat belts to help
reduce the likelihood of head and chest injuries in
frontal crashes.

Operation
Front 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.
How the Front Airbags Work
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.
How the Front Airbags Work
After a front airbag inflates in a crash, you may
see what looks like smoke. This is actually powder
from the airbag's surface. Although the powder
is not harmful, people with respiratory problems
may experience some temporary discomfort. If this
occurs, get out of the vehicle as soon as it is safe to
do so.
Although the driver's and front passenger's airbags
normally inflate within a split 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 protection, and the supplemental
protection offered by the airbag would be minimal.
The total time for inflation and deflation is so fast that most occupants are not
aware that the airbags deployed until they see them lying in front of them.

Front Airbags (SRS)
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 towards 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 towards 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 vehicles equipped with a rollover sensor, side airbags,
and side curtain airbags offer the best protection in a rollover. 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 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 the 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.

Advanced Airbags
Your front airbags have advanced features to reduce the likelihood of
airbag related injuries to smaller occupants.
The driver's advanced front airbag system
includes a seat position sensor.
If the seat is too far forward, the airbag
inflates with less force, regardless of the
severity of the impact.
The passenger's advanced front airbag
system includes weight sensors.
Although Acura recommends against carrying
an infant or small child in front, 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 Airbags
If there is a problem with the driver's seat position
sensor, the SRS indicator will come on and the
airbag will inflate with full (normal) force, regardless
of the driver's seating position.

For both advanced front airbags to work properly:
Do not spill any liquid on or under the seats. tDo not put any object under the passenger’s seat. tMake sure any objects are positioned properly on tthe rear floor. Improperly positioned objects can
interfere with the advanced airbag sensors.
All occupants should sit upright and wear their tseat belts properly.

passenger’s seat.
Do not cover or replace the front seat-back covers
without consulting a dealer.
Improperly replacing or covering front seat-back
covers can prevent your side airbags from properly
