Side Airbags
The side airbags help protect the upper torso and pelvis of the driver or a front passenger
during a moderate-to-severe side impact. They are housed in the outside edge of the
driver’s and front passenger’s seat-backs. Both are marked SIDe AIrBAG.
Side Curtain Airbags
Side curtain airbags help protect the head and torso of the driver and passengers in 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 airbags are designed to deploy in a rollover
or moderate-to-severe side impact. If the SRS control unit
senses that your vehicle is about to roll over, it immediately
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 will inflate even if there
are no occupants on that side of the vehicle.
To get the best protection from the side curtain airbags,
occupants should wear their seat belts properly and sit
upright 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.
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.

Important Facts About your Airbags
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.
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 and driver’s knee 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.
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 attach any objects to the side windows or roof pillars. They can interfere with
the proper operation of the side curtain airbags.
Do not cover or replace the front seat-back covers. This can prevent your side airbags
from properly deploying during a side impact.
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 you to a possible problem.

Airbag System Indicators
If a problem occurs in the airbag system, the SRS indicator comes on and a message
appears on the multi-information display.
SrS (Supplemental r estraint System) Indicator
If the indicator comes on at any other time besides vehicle
start-up, 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. An open glove box can cause serious injury to your passenger in a crash, even
if the passenger is wearing the seat belt.
Always keep the glove box closed while driving.

Passenger Airbag off Indicator
The indicator comes on to alert you that the front
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.
Objects placed on the seat can also cause the indicator to come on.
If the front passenger’s seat is empty, the passenger’s front airbag will not deploy and the
indicator will not come on.
If the indicator comes on with no occupant or objects in the front passenger’s seat,
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 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 go on and off repeatedly if the total weight on the
seat is near the airbag cutoff threshold.

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 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 first 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, call Acura Client
Relations at (800) 382-2238. For Canadian vehicles, call Acura Client Services at (888)
922-8729.
Child Safety
Each year, many children are injured or killed in vehicle crashes because they are either
unrestrained or not properly restrained. In fact, vehicle collisions are the number one cause
of death of children ages 12 and under.
The National Highway Traffic Safety Administration and Transport Canada recommend
that all children ages 12 and under be properly restrained in a rear seat. Some states or
provinces/territories have laws restricting where children may ride.
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.
Protecting Child Passengers—Important Considerations •  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.
•  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 either the lap belt
portion of the lap/shoulder belt or the lower anchors of the LATCH system.
•  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 unattended, 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.
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.

Protecting Infants
An infant must be properly restrained in a rear-facing, reclining child seat until the infant
reaches the seat maker’s weight or height limit for the seat, and the infant is at least one
year old. Many experts recommend use of a rear-facing seat for a child up to two years
old if the child’s height and weight are appropriate for a rear-facing seat.
Child seats must be placed and secured in a rear seating position. Rear-facing child seats
should never be installed in a forward-facing position.
When properly installed, a rear-facing child seat may prevent
the driver or a front passenger from moving their seat all
the way back, or from locking their seat-back in the desired
position. If this occurs, we recommend that you install the
child seat directly behind the front passenger’s seat, move the
seat as far forward as needed, and leave it unoccupied. Or,
you may wish to get a smaller rear-facing child seat. 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 and make sure any unused
seat belt a child can reach is buckled, fully retracted, and locked.
Placing a rear-facing child seat in the front seat can result in serious injury or
death during a crash.
Always place a rear-facing child seat in the rear seat, not the front.
WArNING
WArNING
Protecting Smaller Children
If a child is at least one year old and within the weight range indicated by the child seat
manufacturer, the child should be properly restrained in a firmly secured forward-facing
child seat.
We strongly recommend placing a forward-facing child seat
in a rear seating position.
Placing a forward-facing child seat in the front seat can
be hazardous, even with advanced front airbags that
automatically turn the passenger’s front airbag off. A rear
seat is the safest place for a child.
Placing a forward-facing child seat in the front seat can result in serious
injury or death if the front airbag inflates.
If you must place a forward-facing child seat in front, move the vehicle seat
as far back as possible, and properly restrain the child.
Selecting a Child Seat
Most child seats are LATCH-compatible (Lower Anchors and Tethers for CHildren). Some
have a rigid-type connector, while others have a flexible-type connector. Both are equally
easy to use. Some existing and previously owned child seats can only be installed using
the seat belt. Whichever type you choose, follow the child seat manufacturer’s use and
care instructions as well as the instructions in this manual. Proper installation is key to
maximizing your child’s safety.
In seating positions and vehicles not equipped with LATCH, a LATCH-compatible child
seat can be installed using the seat belt and a top tether for added security. This is
because all child seats are required to be designed so that they can be secured with a lap
belt or the lap part of a lap/shoulder belt. In addition, the child seat manufacturer may
advise that a seat belt be used to attach a LATCH-compatible seat once a child reaches
a specified weight. Please read the child seat owner’s manual for proper installation
instructions.
Important considerations when selecting a child seat
Make sure the child seat meets the following three requirements:
•  The child seat is the correct type and size for the child.
•  The child seat is the correct type for the seating position.
•  The child seat is compliant with Federal Motor Vehicle Safety Standard 213 or Canadian
Motor Vehicle Safety Standard 213.

Installing a LATCH-Compatible Child Seat
A LATCH-compatible child seat can be installed in the second-row seats. A child seat is
attached to the lower anchors with either the rigid or flexible type of connectors.
1. Locate the lower anchors under the marks.
2. Place the child seat on the vehicle seat, then attach
the child seat to the lower anchors according to the
instructions that came with the child seat. Make sure
that the lower anchors are not obstructed by the seat
belt or any other object.
outer seats: Raise the head restraint to its
highest position, then route the tether strap
between the head restraint legs, and secure the
tether strap hook onto the anchor.
Center seat: Lower the center head restraint to
its lowest position, then route the tether strap
over the top of the head restraint and secure the
tether strap hook onto the anchor.
3. Tighten the tether strap as instructed by the child seat
maker.
4. Make sure the child seat is firmly secured by rocking
it forward and back and side to side; little movement
should be felt.
5. Make sure any unused seat belt that a child can reach is
buckled, the lockable retractor is activated, and the belt
is fully retracted and locked.

Installing a Child Seat with a Lap/Shoulder Seat Belt 1. Place the child seat on the vehicle seat.
2. Route the seat belt through the child seat according to
the seat maker’s instructions, and insert the latch plate
into the buckle. Insert the latch plate fully until it clicks.
3. Slowly pull the shoulder part of the belt all the way out
until it stops. This activates the lockable retractor.
4. Let the seat belt completely wind up into the retractor,
then try to pull it out to make sure the retractor is
locked. If you are able to pull the shoulder belt out, the
lockable retractor is not activated. Pull the seat belt all
the way out, and repeat steps 3 – 4.
5. Grab the shoulder part of the seat belt near the buckle,
and pull up to remove any slack from the lap part of the
belt. When doing this, place your weight on the child
seat and push it into the vehicle seat.
6. Make sure the child seat is firmly secured by rocking
it forward and back and side to side; little movement
should be felt.
7. Make sure any unused seat belt that a child can reach is
buckled, the lockable retractor is activated, and the belt
is fully retracted and locked.
To deactivate a lockable retractor, release the buckle and
allow the seat belt to wind up all the way.

Adding Security with a Tether
A tether anchorage point is provided behind each second- and third-row seating position.
A child seat that is installed with a seat belt and comes with a tether can use the tether
for additional security.
Second-row seats
1. For outer seats: Raise the head restraint to its highest
position, then route the tether strap through the head
restraint legs.
For center seat: Lower the head restraint to
its lowest position, then route the tether strap
through the head restraint legs.
2. Make sure the strap is not twisted, and secure the tether
strap hook onto the anchor.
3. Tighten the tether strap as instructed by the child seat
manufacturer.
Third-row seats
1. Pull up the head restraint and push rearward until it
latches, then route the tether strap through the head
restraint legs.
2. Open the anchor cover.
3. Make sure the strap is not twisted, and secure the tether
strap hook onto the anchor.
4. Tighten the tether strap as instructed by the child seat
manufacturer.
Protecting Larger Children
When a child is too big for a child seat, secure the child in a rear seat using the lap/
shoulder seat belt.
Have the child sit upright and all the way back, then ensure the following:
•  The child’s knees bend comfortably over the edge of the
seat.
•  The shoulder belt crosses between the child’s neck and
arm.
•  The lap part of the seat belt is as low as possible, touching
the child’s thighs.
•  The child can stay seated for the whole trip.
Tether anchorage points
Allowing a child age 12 or under to sit in the front can result in injury or
death if the passenger’s front airbag inflates.
If a larger child must ride in front, move the vehicle seat as far to the rear as
possible, have the child sit up properly and wear the seat belt properly, using
a booster seat if needed.
