uuSeat Belts uAbout Your Seat Belts
Safe Driving
■Proper use of seat belts
Follow these guidelines for proper use:
• All occupants should sit upright, well back in the seat, and remain in that position
for the duration of the trip. Slouching an d leaning reduces the effectiveness of
the belt and can increase the chance of serious injury in a crash.
• Never place the shoulder part of a lap/shoulder seat belt under your arm or
behind your back. This could cause very serious injuries in a crash.
• Two people should never use the same seat belt. If they do, they could be very
seriously injured in a crash.
• Do not put any accessories on the seat belts. Devices intended to improve comfort
or reposition the shoulder part of a seat belt can reduce the protective capability
and increase the chance of serious injury in a crash.
Your vehicle monitors front seat belt use. If
the power mode is set to ON before the
driver’s seat belt is fastened, a beeper will
sound and the indicator will blink. If the driver
does not fasten the belt before the beeper
stops, the indicator will remain on.
The beeper will periodically sound and the
indicator will blink while driving until the
driver’s and front passenger’s seat belts are
fastened.■
Seat Belt Reminder
1About Your Seat Belts
If a rear seat passenger moves around and extends
the seat belt, the lockable retractor may activate. If
this happens, release the retractor by unfastening the
seat belt and allow the belt to retract completely.
Then refasten the belt.1 Seat Belt Reminder
The indicator will also come on if a front passenger
does not fasten their seat belt within 6 seconds after
the power mode is set to ON.
When no one is sitting in the front passenger’s seat,
or a child or small adult is riding there, the indicator
will not come on.
This is because the weight sensors in the seat cannot
detect their presence.

side curtain airbags are deployed in a
rollover. The airbag system includes:aTwo SRS (Supplemental Restraint System)

in the center of the steering wheel; the

uuAirbags uFront Airbags (SRS)
Safe Driving
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.
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 they see them lying in front of them.■

How the Front Airbags Work
1 How the Front Airbags Work
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.

■When side curtain airbags deploy in a frontal collision
One or both side curtain airbags may inflate in a moderate to severe angled frontal
collision.
In this case, the side curtain airbags will deploy slightly after the front airbags.Airbag System IndicatorsIf a problem occurs in the airbag system, the SRS indicator will come on and a
message appears on the multi-information display.
■When the power mode is set to ON
The indicator comes on for a few seconds,
then goes off. This tells you the system is
working properly.
If the indicator comes on at any other time, or does not come on at all, have the
system checked by a dealer as soon as possible. If you don’t, your airbags and seat
belt tensioners may not work properly when they are needed.

Ignoring the SRS indicator can result in
serious injury or death if the airbag systems
or tensioners do not work properly.
Have your vehicle checked by a dealer as
soon as possible if the SRS indicator alerts

uuAirbags uAirbag Care
Safe Driving
Airbag CareYou 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 tensioner has been activated, it must be
replaced.■When the vehicle has been in a moderate-to-severe collision
Even if the airbags did not inflate, 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 modify a front seat without consulting a dealer
This would likely disable the driver’s seat position sensor or the weight sensors in the
passenger’s seat. If it is necessary to remove or modify a front seat to accommodate
a person with disabilities, contact an Acura dealer. For U.S. vehicles, Acura Client
Relations at 800-382-2238 and for Canadian vehicles, Acura Client Services at 1-
866-78-ACURA.
1 Airbag Care
We recommend against the use of salvaged airbag
system components, including the airbag, tensioners,
sensors, and control unit.
