SRS airbag system warning light

If the seatbelt buckle switch and/or front
passenger’s occupant detection system
have failed, the SRS airbag system warn-
ing light will illuminate. Have the system
inspected by your SUBARU dealer imme-
diately if the SRS airbag system warning
light illuminates.
If your vehicle has sustained impact, this
may affect the proper function of the
SUBARU advanced frontal airbag system.
Have your vehicle inspected at your
SUBARU dealer. Do not use the front
passenger’s seat while driving the vehicle
to your SUBARU dealer.

NOTE

The front passenger’s SRS side airbag
and SRS curtain airbag are not con-
trolled by the SUBARU advanced fron-
tal airbag system.

Occupant detection system

Occupant detection sensors

The occupant detection system sensors
are installed between the seat and seat
rails, and monitor the physique and pos-
ture of the front passenger. Using this
information, the occupant detection sys-
tem determines whether the front passen-
ger’s SRS frontal airbag should be de-
ployed or not.

WARNING

Do not kick the front passenger seat
or subject it to severe impact. Other-
wise, the SRS airbag system warn-
ing light may illuminate to indicate a
malfunction of the front passenger
occupant detection system. In this

cially under either of the following
conditions.

when placed on the front passen-

ger’s seat while connected to the
accessory power outlet

when used by the front passen-

ger

*Example: cell phones, laptops, por-
table music players, or electronic
games

If either of the following situations
occurs when using an electronic
device in the vehicle, at first try to
relocate that device to avoid it
creating any interference.

The SRS airbag system warning

Also, if luggage or electronic devices are
placed on the front passenger’s seat, this
may adversely affect the ability of the
system to determine deployment. This
may prevent the front passenger’s frontal
airbag ON and OFF indicators from work-
ing properly. Check that the indicators
work properly.
When the OFF indicator turns off and the
ON indicator illuminates, the front passen-
ger’s frontal airbag may deploy during a
collision. Remove luggage and electronic
devices from the front passenger’s seat.

Conditions in which front passen-
ger’s SRS frontal airbag is not
activated

The front passenger’s SRS frontal airbag
will not be activated when any of the
following conditions are met regarding
the front passenger’s seat:
.

The seat is empty.

The seat is equipped with an appro-

priate child restraint system and an infant
or a child is restrained in it. (See WARN-
ING that follows.)
.

The front passenger’s occupant detec-

tion system is malfunctioning.

WARNING

NEVER INSTALL A CHILD SEAT IN
THE FRONT SEAT EVEN IF THE
FRONT PASSENGER’S SRS FRON-
TAL AIRBAG IS DEACTIVATED. Be
sure to install it in the REAR seat in a
correct manner. Also, it is strongly
recommended that any forward fa-
cing child seat or booster seat be
installed in the REAR seat, and that
even children who have outgrown a
child restraint system be also seated
in the REAR seat. This is because
children sitting in the front passen-
ger’s seat may be killed or severely
injured should the front passenger’s

SRS frontal airbag deploy. REAR
seats are the safest place for chil-
dren.

CAUTION

When the front passenger’s seat is
occupied by an infant in an appro-
priate child restraint system, ob-
serve the following precautions.
Failure to do so may interfere with
the proper operation of the occupant
detection system, activating the
front passenger’s SRS frontal airbag
even though that seat is occupied by
the infant in the child restraint
system.

Do not place any article (includ-

ing electronic devices) on the
seat other than the infant in the
child restraint system.

Do not place more than one infant

in the child restraint system.

3. By referring to the child restraint
manufacturer’s recommendations as well
as the child restraint system installation
procedures in “Child restraint systems”
F1-26, correctly install the child restraint

system.
4. Turn the ignition switch to the “ON”
position and make sure that the front
passenger’s frontal airbag ON indicator
turns off and the OFF indicator illuminates.

If still the ON indicator remains illuminated
while the OFF indicator turns off, take the
following actions.
.

Ensure that no article is placed on the

seat other than the child restraint system
and the child occupant.
.

Ensure that the backward-forward po-

sition and seatback of front passenger’s
seat are locked into place securely by
moving the seat back and forth.

If the ON indicator still remains illuminated
while the OFF indicator turns off after
taking relevant corrective actions de-
scribed above, relocate the child restraint
system to the rear seat and immediately
contact your SUBARU dealer for an
inspection.

NOTE

When a child who has outgrown a child
restraint system or a small adult is
seated in the front passenger’s seat,
the SUBARU advanced frontal airbag
system may or may not activate the
front passenger’s SRS frontal airbag

depending on the occupant’s seating
posture. Children should always wear a
seatbelt when sitting in the seat irre-
spective of whether the airbag is deac-
tivated or activated. If the front passen-
ger’s SRS frontal airbag is activated
(the ON indicator remains illuminated
while the OFF indicator turns off), take
the following action.
.

Ensure that no article is placed on

the seat other than the occupant.

If the ON indicator still remains illumi-
nated while the OFF indicator turns off
despite the fact that the actions noted
above have been taken, seat the child/
small adult in the rear seat and imme-
diately contact your SUBARU dealer for
an inspection. Even if the system has
passed the dealer inspection, it is
recommended that on subsequent trips
the child/small adult always take the
rear seat.

Children who have outgrown a child
restraint system should always wear the
seatbelt irrespective of whether the airbag
is deactivated or activated.

Conditions in which front passen-
ger’s SRS frontal airbag is activated

The front passenger’s SRS frontal airbag
will be activated for deployment upon
impact when any of the following condi-
tions are met regarding the front passen-
ger’s seat.
.

When the seat is occupied by an adult.

When certain items (e.g. jug of water)

are placed on the seat.

This can be caused by the adult incorrectly
sitting in the front passenger’s seat.
1. Turn the ignition switch to the “LOCK”/
“OFF” position.
2. Ask the front passenger to set the
seatback to the upright position, sit up
straight in the center of the seat cushion,
correctly fasten the seatbelt, position his/
her legs out forward, and adjust the seat to
the rearmost position.

3. Turn the ignition switch to the “ON”
position.

If the OFF indicator remains illuminated
while the ON indicator remains off, take the
following actions.
1. Turn the ignition switch to the “LOCK”/
“OFF” position.
2. Make sure that the front passenger
does not use a blanket, seat cushion, seat
cover, seat heater or massager, etc.
3. If wearing excessive layers of clothing,
the front passenger should remove any
unnecessary items before sitting in the
front passenger’s seat, or should sit in a
rear seat.
4. Turn the ignition switch to the “ON”
position and wait 6 seconds to allow the
system to complete self-checking. Follow-
ing the system check, both indicators turn
off for 2 seconds. Now, the ON indicator
should illuminate while the OFF indicator
remains off.

If the OFF indicator still remains illumi-
nated while the ON indicator remains off,
ask the occupant to move to the rear seat
and immediately contact your SUBARU
dealer for an inspection.

Operation

Driver’s side

Passenger’s side

SRS AIRBAGs deploy as soon as a collision occurs.

After deployment, SRS AIRBAGs start to deflate immediately so that the driver’s vision is not
obstructed.

The SRS airbags can function only when
the ignition switch is in the “ON” position.

The SUBARU advanced frontal airbag
system is designed to determine the
activation or deactivation condition of the
front passenger’s SRS frontal airbag de-
pending on the characteristic of item(s) or
person on the front passenger’s seat
monitored by the front passenger’s occu-
pant detection system sensor. For this
reason, only the driver’s SRS frontal
airbag may deploy in the event of a
collision, but this does not mean failure of
the system.

If the following sensors detect a predeter-
mined amount of force during a frontal
collision, the control module sends signals
to the airbag module(s) (only driver’s
module or both driver’s and front passen-
ger’s modules) instructing the module(s) to
inflate the SRS frontal airbag(s).
.

the front sub sensors

the impact sensors in the airbag control

module

On the driver’s side, the SRS knee airbag
also inflates with the SRS frontal airbag.

(91,1)

北米Model "A1350BE-A" EDITED: 2018/ 4/ 20

The driver’s and front passenger’s SRS
frontal airbags use dual stage inflators.
The two inflators of each airbag are
triggered either sequentially or simulta-
neously, depending on the severity of
impact, in the case of the driver’s SRS
frontal airbag and depending on the
severity of impact and the characteristic
of item(s) or person on the seat in the case
of the front passenger’s SRS frontal air-
bag.

After deployment

After deployment, the SRS airbag imme-
diately starts to deflate so that the driver’s
vision is not obstructed and the driver’s
ability to maintain control of the vehicle is
not impaired. The time required from
detecting impact to the deflation of the
SRS airbag after deployment is shorter
than the blink of an eye.

Both when only the driver’s SRS frontal
airbag deploys and the driver’s and front
passenger’s SRS frontal airbags deploy,
the driver’s and front passenger’s seatbelt
pretensioners operate at the same time.

When the SRS airbag deploys, a sudden,
fairly loud inflation noise will be heard and
some smoke will be released. These
occurrences are a normal result of the
deployment. This smoke does not indicate
a fire in the vehicle.

CAUTION

Do not touch the SRS airbag system
components around the steering
wheel and dashboard with bare
hands right after deployment. Doing
so can cause burns because the
components can be very hot as a
result of deployment.

Example of the type of accident

The driver’s SRS frontal airbag and front
passenger’s SRS frontal airbag are de-
signed as follows.
.

to deploy in the event of an accident

involving a moderate to severe frontal
collision
.

to function on a one-time-only basis

The driver’s SRS frontal airbag and front
passenger’s SRS frontal airbag are not
designed as follows.
.

to deploy in most lesser frontal im-

pacts

to deploy in most side or rear impacts or

in most rollover accidents

*1: Because the necessary protection can be
achieved by the seatbelt alone.

*2: Because deployment of only the driver’s
SRS frontal airbag or both the driver’s and front

passenger’s SRS frontal airbags would not
protect the occupant in those situations.

SRS airbag deployment depends on the
level of force experienced in the passen-
ger compartment during a collision. That
level differs from one type of collision to
another, and it may have no bearing on the
visible damage done to the vehicle itself.

Example of accident in which the
driver’s/driver’s and front pas-
senger’s SRS frontal airbag(s)
will most likely deploy

A head-on collision against a thick con-
crete wall at a vehicle speed of 12 to 19
mph (20 to 30 km/h) or higher activates
only the driver’s SRS frontal airbag or both
driver’s and front passenger’s SRS frontal
airbags. The airbag(s) will also be acti-

vated when the vehicle is exposed to a
frontal impact similar in fashion and
magnitude to the collision described
above.

Examples of the types of acci-
dents in which it is possible that
the driver’s/driver’s and front
passenger’s SRS frontal
airbag(s) will deploy

Only the driver’s SRS frontal airbag or both
driver’s and front passenger’s SRS frontal
airbags may be activated when the vehicle
sustains a hard impact in the undercar-
riage area from the road surface (such as
when the vehicle plunges into a deep ditch,
is severely impacted or knocked hard
against an obstacle on the road such as
a curb).

Examples of the types of accidents in which deployment of the driver’s/
driver’s and front passenger’s SRS frontal airbag(s) is unlikely to occur

The vehicle strikes an object, such as a
telephone pole or sign pole.

The vehicle slides under the load bed of a
truck.

The vehicle sustains an oblique offset
frontal impact.

The vehicle sustains an offset frontal
collision.

The vehicle strikes an object that can
move or deform, such as a parked
vehicle.

There are many types of collisions which
might not necessarily require deployment
of driver’s/driver’s and front passenger’s
SRS frontal airbag(s). In the event of
accidents like those illustrated, the dri-
ver’s/driver’s and front passenger’s SRS
frontal airbag(s) may not deploy depend-
ing on the level of accident forces involved.

Examples of the types of acci-
dents in which the driver’s/dri-
ver’s and front passenger’s SRS
frontal airbag(s) are not de-
signed to deploy in most cases

The driver’s and front passenger’s SRS
frontal airbags are not designed to deploy
in most of the following cases.
.

If the vehicle is struck from the side or

from behind
.

If the vehicle rolls onto its side or roof

If the vehicle is involved in a low-speed

frontal collision

First impact

Second impact

In an accident where the vehicle is
impacted more than once, the driver’s
and/or front passenger’s SRS frontal
airbag(s) will deploy only once on the first
impact.

Example: In the case of a double collision,
first with another vehicle, then against a

concrete wall in immediate succession,
once either or both of the driver’s and front
passenger’s SRS frontal airbags is/are
activated on the first impact, it/they will
not be activated on the second impact.

SRS side airbag and SRS
curtain airbag

SRS side airbag

The SRS side airbag is stored in the door
side of each front seat seatback, which
bears an “SRS AIRBAG” label.

In a moderate to severe side impact
collision, the SRS side airbag on the
impacted side of the vehicle deploys
between the occupant and the door panel
and supplements the seatbelt by reducing
the impact on the occupant’s chest and

waist. The SRS side airbag operates only
for front seat occupants.

SRS curtain airbag

Your vehicle is equipped with a SUBARU
SRS curtain airbag system that complies
with the Federal Motor Vehicle Safety
Standard (FMVSS) No. 226.
The SRS curtain airbag on each side of the
cabin is stored in the roof side (between
the front pillar and a point over the rear
seat). An “SRS AIRBAG” mark is located
at the top of each center pillar.
In a moderate to severe side impact
collision, the SRS curtain airbag on the
impacted side of the vehicle deploys
between the occupant and the side win-
dow and supplements the seatbelt by
reducing the impact on the occupant’s
head.
In a rollover, SRS curtain airbags on both
sides of the vehicle deploy between the
occupant and the side window and supple-
ment the seatbelt by reducing the impact to
the occupant’s head.

In an offset frontal collision, SRS curtain
airbags on both sides of the vehicle deploy
between the occupant and the side win-
dow and supplement the seatbelt by
reducing the impact to the occupant’s
head and chest.

Operation

The SRS side airbag and SRS curtain
airbag can function only when the ignition
switch is in the “ON” position.

The following airbags deploy indepen-
dently of each other since each has its
own impact sensor.
.

Driver’s SRS side airbag

Front passenger’s SRS side airbag

SRS curtain airbag (right-hand side)

SRS curtain airbag (left-hand side)

Therefore, they may not both deploy in the
same accident. Also, the SRS side airbag
and SRS curtain airbag deploys indepen-
dently of the driver’s and front passenger’s
SRS frontal airbags in the steering wheel
and instrument panel.

An impact sensor, which senses impact
force, is located in each of the following
locations.
.

In the left and right front doors

In the left and right center pillars

In the left and right rear wheel houses

Under the rear center seat

A rollover sensor is also located inside the
airbag control module.

After deployment

After the deployment, the SRS side airbag
immediately starts to deflate. The time
required from detection of an impact to
deflation of an SRS side airbag after
deployment is shorter than the blink of an
eye.

The SRS curtain airbag remains inflated
for a while following deployment then
slowly deflates.

The SRS side airbag and SRS curtain
airbag deploy even when no one occupies
the seat on the side on which an impact is
applied.

When the SRS side airbag and SRS
curtain airbag deploy, a sudden, fairly loud
inflation noise will be heard and some
smoke will be released. These occur-
rences are a normal result of the deploy-
ment. This smoke does not indicate a fire
in the vehicle.

CAUTION

Do not touch the SRS side airbag
system components around the
front seat seatback with bare hands
right after deployment. Doing so can
cause burns because the compo-
nents can be very hot as a result of
deployment.

After deployment, do not touch any
part of the SRS curtain airbag sys-
tem (from the front pillar to the part
of the roof side over the rear seat).
Doing so can cause burns because
the components can be very hot as a
result of deployment.

Example of the type of accident

The SRS side airbag and SRS curtain
airbag are designed as follows:
.

to deploy in the event of an accident

involving a moderate to severe side impact
collision
.

to function on a one-time-only basis.

The SRS side airbag and SRS curtain
airbag are not designed to deploy in the
following cases:
.

in most lesser side impact

in most frontal or most rear impacts

(because the SRS side airbag and SRS
curtain airbag deployment would not pro-
tect the occupant in those situations)

The SRS curtain airbags are also de-
signed to deploy when the vehicle is in an
extremely inclined state such as during a
rollover. They are not designed to deploy in
most lesser inclined state.

SRS side airbag and SRS curtain airbag
deployment depend on the level of force

experienced in the passenger compart-
ment during a side impact collision. That
level differs from one type of collision to
another, and it may have no bearing on the
visible damage done to the vehicle itself.

Example of the type of accident in
which the SRS side airbag will
most likely deploy.

A severe side impact near the front seat.
