uuAirbagsuFront Airbags (SRS)
40Safe Driving
Your front airbags have advanced features to help 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
has 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
1Advanced 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.•Do not put any object under the passenger’s seat.•Make sure any objects are positioned properly on
the floor. Improperly positioned objects can
interfere with the advanced airbag sensors.•All occupants should sit upright and wear their seat
belts properly.•Do not place any cover over the passenger side
dashboard.
Make sure the floor mat behind the front passenger’s
seat is hooked to the floor mat anchor. An improperly
placed mat can interfere with the advanced airbag
sensors.

Safe Driving
Side AirbagsThe side airbags help protect the upper torso of the driver or a front 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
1Side Airbags
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.
If the impact is on the passenger's side, the airbag
may not deploy when there is no passenger in the
front passenger 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
deploying during a side impact.

■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 towards
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.

uuAirbagsuSide Airbags
Safe Driving
To reduce the likelihood that a front passenger may be injured by an inflating side
airbag, the passenger side airbag is automatically turned off when:
•The height sensors detect a child or short-statured adult is seated in the front
passenger seat.
•The position sensor detects that the front passenger is leaning into the
deployment path of the side airbag.
When the side airbag cutoff system is activated, the side airbag off indicator comes
on.2Side Airbag Off Indicator P. 47If the side airbag off indicator comes on, have the passenger sit upright. A few
seconds after the passenger is sitting properly, the side airbag will automatically be
turned on, and the indicator will go off.
If the front passenger is a child, stop when it is safe to do so, and have the child sit
properly restrained in a rear seat.■Side Airbag Cutoff System■Side Airbag Off Indicator

uuAirbagsuSide Curtain Airbags
Safe Driving
Side Curtain AirbagsThe side curtain airbags help protect the heads of the driver and passengers in outer
seating positions during a moderate-to-severe side impact or rollover.
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 moderate-to-severe side impact or
rollover.■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.■Housing Locations
1Side Curtain Airbags
The side curtain airbags are most effective when an
occupant is wearing their seat belt properly and
sitting upright, well back in their seat.
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.
If the impact is on the passenger side, the side curtain
airbag deploys even if there is no passenger in the
passenger seat.

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.

■When the passenger 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 front passenger’s weight
sensors detect 65 lbs (29 kg) or less, the
weight of an infant or small child, on the seat.
Infants and small children should always ride properly restrained in a back seat.
2Child Safety P. 49Objects placed on the seat can also cause the indicator to come on.
If the front passenger seat is empty, the passenger’s front airbag will not deploy and
the indicator will not come on.■Passenger Airbag Off Indicator
1Passenger Airbag Off Indicator
If the indicator comes on with no front passenger and
no objects on the passenger’s seat, or with an adult
riding there, something may be interfering with the
weight sensors. Such as:•An object hanging on the seat or in the seat-back
pocket.•A child seat or other object pressing against the
rear of the seat-back.•A rear passenger pushing or pulling on the back of
the front passenger’s seat.•The front seat or seat-back is forced back against
an object on the seat or floor behind it.•An object placed under the front passenger’s seat.
If none of these conditions exist, have your vehicle
checked by a dealer as soon as possible.
The passenger airbag off indicator may come on and
goes off repeatedly if the total weight on the seat is
near the airbag cutoff threshold.

■When the side airbag off indicator comes on
This indicator comes on if the passenger’s side airbag has been turned off because
the passenger is too small to be sitting in the front seat, is slouching or not sitting
upright, or has leaned into the airbag’s deployment path.
Unless the passenger is a smaller statured adult or a child, the indicator should go
off when the passenger returns to a proper upright sitting position.■Side Airbag Off Indicator

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 passenger’s weight
sensors. 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 you can also contact
Acura Client Relations at 800-382-2238. For Canadian vehicles you can also contact
Canadian Acura Client Service at 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 SafetyProtecting Child PassengersEach year, many children are injured or killed in vehicle crashes because they are
either unrestrained or not properly restrained. In fact, vehicle accidents are the
number one cause of death of children age 12 and under.
To reduce the number of child deaths and injuries, every state, Canadian province
and territory requires that infants and children 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 sitting 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 children of all sizes and
ages are safer when they are properly
restrained in a rear seat.
1Protecting Child Passengers
The National Highway Traffic Safety
Administration and Transport Canada recommend that
all children age 12 and under be properly restrained in a
rear seat. Some states or provinces/territories have laws
restricting where children may ride.
3
WARNING
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.
