SUBARU IMPREZA WRX 2013 4.G Repair Manual

1-34Seat, seatbelt and SRS airbags
Please contact your SUBARU dealer if
you have any question regarding the
installation of a child restraint system.
CAUTION
Always remove the head restraint
when mounting a child restraint
system with a top tether. Otherwise,
the top tether cannot be fastened
tightly. *SRS airbag (Supplemental
Restraint System airbag)
*SRS: This stands for supplemental re-
straint system. This name is used be-
cause the airbag system supplements thevehicle
’s seatbelts.
Your vehicle is equipped with a crash
sensing and diagnostic module, which will
record the use of the seatbelt by the front
passenger when any of the SRS frontal,
side and curtain airbags deploys.
Your vehicle is equipped with a supple-
mental restraint system in addition to a
lap/shoulder belt at each front seating
position and each rear window-side seat-
ing positions. The supplemental restraint
system (SRS) consists of six airbags.
The configurations are as follows.. Driver ’s and front passenger ’s frontal
airbags. Driver ’s and front passenger ’s side
airbags. Curtain airbags (for driver, front pas-
senger, and window-side rear passen- gers)
These SRS airbags are designed only
to be a supplement to the primary
protection provided by the seatbelt.
The system also controls front seatbelt pretensioners. For operation instructions
and precautions concerning the seatbelt
pretensioner, refer to
“Front seatbelt pre-
tensioners ”F 1-19.
& General precautions regard-
ing SRS airbag system
WARNING
. To obtain maximum protection in
the event of an accident, the
driver and all passengers in the
vehicle should always wear seat-
belts when the vehicle is moving.
The SRS airbag is designed only
to be a supplement to the primary
protection provided by the seat-
belt. It does not eliminate the
need to fasten seatbelts. In com-
bination with the seatbelts, it
offers the best combined protec-
tion in case of a serious accident.
Not wearing a seatbelt increases
the chance of severe injury or
death in a crash even when the
vehicle has the SRS airbag.
For instructions and precautions
concerning the seatbelt system,
refer to “Seatbelts ”F 1-11.
. The SRS side airbag and SRS
curtain airbag are designed only

to be a supplement to the primary
protection provided by the seat-
belt. They do not eliminate the
need to fasten seatbelts. It is also
important to wear your seatbelt
to help avoid injuries that can
result when an occupant is not
seated in a proper upright posi-tion.
WARNING
The SRS airbags deploy with con-
siderable speed and force. Occu-
pants who are out of proper position
when the SRS airbag deploys could
suffer very serious injuries. Be-
cause the SRS airbag needs enough
space for deployment, the driver should always sit upright and well
back in the seat as far from the
steering wheel as practical while
still maintaining full vehicle control,
and the front passenger should
move the seat as far back as
possible and sit upright and well
back in the seat.WARNING
. Do not sit or lean unnecessarily
close to either front door. The
SRS side airbag is stored in both
front seat seatbacks next to the
door, and it provides protection
by deploying rapidly (faster than
the blink of an eye) in the event of
a side impact collision. However, theforceofSRSsideairbag
deployment may cause injuries
if your head or other parts of the
body are too close to the SRS
side airbag.
. Since your vehicle is equipped
with SRS curtain airbags, do not
sit or lean unnecessarily close to
the front or rear door on either
side. Also, do not put your head,
arms and hands out of the win-
dow. 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), and it provides protection
by deploying rapidly (faster than
the blink of an eye) in the event of
a side impact. However, the force
of its deployment may cause
injuries if your head is too close
to it.
. Do not sit or lean unnecessarily
close to the SRS airbag. Because
the SRS airbag deploys with
considerable speed (faster than
the blink of an eye) and force to
protect the occupant in high
speed collisions, the force of an
airbag can injure an occupant
whose body is too close to the
SRS airbag.

It is also important to wear your
seatbelt to help avoid injuries
that can result when the SRS
airbag contacts an occupant not
in proper position such as one
thrown forward during pre-acci-
dent braking.
Even when properly positioned,
there remains a possibility that
an occupant may suffer minor
injuries such as abrasions and
bruises to the face or arms
because of the SRS airbag de-
ployment force.WARNING
. Do not rest your arm on either
front door or its internal trim. You
could be injured in the event of
SRS side airbag deployment.
. Do not place any objects over or
near the SRS airbag cover or
between you and the SRS airbag.
If the SRS airbag deploys, those
objects could interfere with its
proper operation and could be
propelled inside the vehicle and
cause injury.WARNING
Do not put any objects over the
steering wheel pad and dashboard.
If the SRS frontal airbag deploys,
these objects could interfere with its
proper operation and could be pro-
pelled inside the vehicle, causing
injury.
WARNING
Do not attach accessories to the
windshield, or fit an extra-wide mir-
ror over the rear view mirror. If the
SRS airbag deploys, those objects
could become projectiles that could
seriously injure vehicle occupants.

WARNING
. Do not attach accessories to the
door trim or near either SRS side
airbags and do not place objects
near the SRS side airbags. In the
event of SRS side airbag deploy-
ment, they could be propelled
dangerously toward the vehicle ’s
occupants and cause injuries.
. Do not attach a hands-free micro-
phone or any other accessory to
a front pillar, a center pillar, a rear
pillar, the windshield, a side win-
dow, an assist grip, or any other
cabin surface that would be near
a deploying SRS curtain airbag.
A hands-free microphone or other accessory in such a loca-
tion could be propelled through
the cabin with great force by the
curtain airbag, or it could prevent
correct deployment of the curtain
airbag. In either case, the result
could be serious injuries.
. Never hang or place coat hangers
or other hard or pointed objects
near the side windows. If such
items are present when the SRS
curtain airbags deploy, they
could be thrown through the
passenger compartment and
cause serious injuries. They
could also prevent proper opera-
tion of the SRS curtain airbags.
Before hanging clothing on the
coat hooks, make sure there are
no sharp objects in the pockets.
Hang clothing directly on the
coat hooks without using hang-ers.WARNING
Do not put any kind of cover or
clothes or other objects over either
front seatback and do not attach
labels or stickers to the front seat
surface on or near the SRS side
airbag. They could prevent proper
deployment of the SRS side airbag,
reducing protection available to the
front seat ’s occupant.

WARNING
Put children aged 12 and under in
the rear seat properly restrained at
all times. The SRS airbag deploys
with considerable speed and force
and can injure or even kill children,
especially if they are 12 years of age
and under and are not restrained or
improperly restrained. Because chil-
dren are lighter and weaker than
adults, their risk of being injured
from deployment is greater.
For that reason, we strongly recom-
mend that ALL children (including
those in child seats and those that
have outgrown child restraint de-
vices) sit in the REAR seat properly restrained at all times in a child
restraint device or in a seatbelt,
whichever is appropriate for thechild
’s age, height and weight.
Secure ALL types of child restraint
devices (including forward facing
child seats) in the REAR seats at
all times.
According to accident statistics,
children are safer when properly
restrained in the rear seating posi-
tions than in the front seating posi-tions.
For instructions and precautions
concerning the child restraint sys-
tem, refer to “Child restraint sys-
tems ”F 1-21.
WARNING
NEVER INSTALL A REARWARD FA-
CING CHILD SEAT IN THE FRONT
SEAT. DOING SO RISKS SERIOUS
INJURY OR DEATH TO THE CHILD
BY PLACING THE CHILD ’S HEAD
TOO CLOSE TO THE SRS AIRBAG.
WARNING
Never allow a child to stand up or
kneel on the front passenger ’s seat.
The SRS airbag deploys with con-
siderable force and can injure or
even kill the child.

WARNING
Never hold a child on your lap or in
your arms. The SRS airbag deploys
with considerable force and can
injure or even kill the child.
WARNING
. Never allow a child to do the
following. – Kneel on any passenger ’s
seat facing the side window
– Wrap his/her arms around the
front seat seatback
– Put his/her head, arms or
other parts of the body out of
the window
In the event of an accident, the force of SRS side airbag and/or
SRS curtain airbag deployment
could injure the child seriously
because his/her head, arms or
other parts of the body are too
close to the SRS side airbag and/
or SRS curtain airbag.
. Since your vehicle is also
equipped with a front passen-ger ’s SRS frontal airbag, children
aged 12 and under should be
placed in the rear seat anyway
and should be properly re-
strained at all times.

CAUTION
. When the SRS airbag deploys,
some smoke will be released.
This smoke could cause breath-
ing problems for people with a
history of asthma or other
breathing trouble. If you or your
passengers have breathing pro-
blems after SRS airbag deploys,
get fresh air promptly.
. A deploying SRS airbag releases
hot gas. Occupants could get
burned if they come into direct
contact with the hot gas.
NOTE
When you sell your vehicle, we urge
you to explain to the buyer that it is
equipped with SRS airbags by alerting
the buyer to the applicable section in
this Owner ’s Manual.

&SUBARU advanced frontal
airbag system, SRS side air-
bag and SRS curtain airbag
Your vehicle is equipped with a SUBARU
advanced frontal airbag system that com-
plies with the new advanced frontal airbag
requirements in the amended Federal
Motor Vehicle Safety Standard (FMVSS)
No. 208.
The SUBARU advanced frontal airbag
system automatically determines the de-
ployment force of the driver ’s SRS frontal
airbag at the time of deployment as well as
whether or not to activate the frontpassenger ’s SRS frontal airbag and, if
activated, the deployment force of the
SRS frontal airbag at the time of deploy-ment.
Your vehicle has warning labels on the driver ’s and front passenger ’s sun visors
beginning with the phrase “EVEN WITH
ADVANCED AIR BAGS ”and a tag
attached to the glove box lid beginning
with the phrase “Even with Advanced Air
Bags ”. Make sure that you carefully read
the instructions on the warning labels andtag.
Always wear your seatbelt. The SUBARU
advanced frontal airbag system is a
supplemental restraint system and must
be used in combination with a seatbelt. All occupants should wear a seatbelt or be
seated in an appropriate child restraintsystem.
For the locations of the driver
’sSRS
frontal airbag, front passenger ’sSRS
frontal airbag, SRS side airbag and SRS
curtain airbag, refer to “Components ”F 1-
41.
In a moderate to severe frontal collision,
the driver ’s and front passenger ’s SRS
frontal airbags deploy and supplement the
seatbelts by reducing the impact on thedriver ’s and front passenger ’s head and
chest.
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.
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
window and supplements the seatbelt by
reducing the impact on the occupant ’s
head.
NOTE
The SRS side airbag, SRS curtain air-
bag and seatbelt pretensioner are not controlled by the SUBARU advanced
frontal airbag system. !
Driver ’s SRS frontal airbag
The driver ’s SRS frontal airbag uses a
dual stage inflator. The inflator operates in
different ways depending on the severity
of impact.
Have the system inspected by your
SUBARU dealer immediately if the SRS
airbag system warning light illuminates. ! Front passenger ’s SRS frontal air-
bag
The front passenger ’s SRS frontal airbag
uses a dual stage inflator. The inflator
operates in different ways depending on
the severity of impact.
The total load on the seat is monitored by
the occupant detection system ’s weight
sensor located under the seat.
The system has another sensor that
monitors the tension of the front passen-
ger seatbelt. Using the total seat load and
seatbelt tension data from the sensors,
the occupant detection system determines
whether the front passenger ’s SRS frontal
airbag should or should not be inflated.
The occupant detection system may not
inflate the front passenger ’s SRS frontal
airbag even when the driver ’s SRS frontal
airbag deploys. This is normal. Seat, seatbelt and SRS airbags
