Examples of the types of accidents in which the SRS frontal
airbag will basically not deploy.
The SRS frontal airb ag is b asic ally not d esig ned to d ep loy if the
vehic le is struc k from sid e or from b ehind , or if i t rolls onto its sid e or
roof, or if it is involved in a low-sp eed frontal c ollision.
HB1044AB
The vehicle is struck from the side.
HB0313
HB1043BB
In an ac c id ent where the vehic le is imp ac ted more t han onc e, the
SRS frontal airb ag d ep loys only onc e on the first i mp ac t.
Examp le: In the c ase of a d oub le c ollision, first w ith another vehic le,
then ag ainst a c onc rete wall in immed iate suc c essio n, the SRS frontal
airb ag is ac tivated on the first imp ac t b ut not on the sec ond .

SRS side airbag (if equipped)
WARNING
The SRS aide airbag is designed as only a supplement to the
primary protection provided by the seatbelt. It does not do away with the need to fasten seatbelts. It is also important to wear your
seatbelt to help avoid injuries that can result when an occupant isnot seated in a proper upright position. 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 thanthe blink of an eye) in the event of a side impact collision. Howev-
er, the force of SRS side airbag deployment may cause injuries ifyour head or other body parts are too close to the SRS side air-bag. Do not rest your arm on either front door or its internal trim. It
could be injured in the event of SRS side airbag deployment. Never allow a child to kneel on the front passenger ’s seat fac-
ing the side window or to wrap his/her arms around the front seat
seatback. In the event of an accident, the force of SRS side airbag
deployment could seriously injure or even kill the child becausehis/her head or arms or other body parts are close to the side air-bag. Since your vehicle is also equipped with a passenger ’s SRS
frontal airbag, children aged 12 and under should be placed inthe rear seat anyway and should be properly restrained at alltimes.

HB0352
Do not sit or learn unnecessary
close to the front door.Do not rest your arm on either front door or its internal trim.
HB0354
Never allow a child to kneel on the front passenger ’s seat facing the side
window.
HB0355
Never allow a child to wrap his/her arms around the front seatback.
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 the SRS side airbag deployment, they could bepropelled dangerously toward the vehicle ’s occupants and cause
injuries. Do not put any kind of cover or clothes or other objects over
either front seatback and do not attach labels or stickers to thefront seat surface on or near the SRS side airbag. They could pre-vent proper deployment of the SRS side airbag, reducing protec-tion available to the front seat ’s occupant.

Do not put any kind of cover over either seatback.Do not attach accessories to the door trim or near either side airbag and do not place objects near either side air- bag.

The SRS sid e airb ag is stored in the d oor sid e of e ac h front seatb ac k,
whic h b ears an “SRS AIRBAG ” lab el.
In a mod erate to severe sid e imp ac t c ollision, the SRS sid e airb ag on the
imp ac ted sid e of the vehic le d ep loys b etween the oc c up ant and the
d oor p anel and sup p lements the seatb elt b y red uc ing the imp ac t on the
oc c up ant ’s c hest.
Operation
CAUTION
Do not touch the SRS side airbag system components around the front seatback with bare hands right after deployment. Doing socan cause burns because the components can be very hot as aresult of deployment.

SRS side airbag deploys as soon as a collision occurs.
After deployment, SRS sideairbag starts to deflate immedi-
ately. HB0359
The SRS sid e airb ag c an func tion only when the ig nition switc h is in
the “ON ” p osition.
The d river ’s and front p asseng er ’s SRS sid e airb ag s d ep loy ind ep en-
d ently of eac h other sinc e eac h has its own imp ac t sensor. Also, the
SRS sid e airb ag d ep loys ind ep end ently of the fronta l airb ag s in the
steering wheel and instrument p anel.
An imp ac t sensor is inc orp orated into eac h of the v ehic le’s c enter p il-
lars. If either sensor d etec ts a c ertain p red etermi ned amount of forc e
d uring a sid e imp ac t c ollision, the c ontrol mod ule send s a sig nal to
the sid e airb ag mod ule on the imp ac ted sid e of the vehic le, instruc t-
ing it to inflate the SRS sid e airb ag . Then the sid e airb ag mod ule p ro-
d uc es g as, whic h instantly inflates the SRS sid e ai rb ag . After the d e-
p loyment, the SRS sid e airb ag immed iately starts to d eflate. The time
req uired from d etec ting imp ac t to d eflating of the SRS sid e airb ag af-
ter d ep loyment is shorter than the b link of eye.
The SRS sid e airb ag d ep loys even when no one oc c up i es the seat on
the sid e of whic h an imp ac t is ap p lied .

1-64When the SRS sid e airb ag d ep loys, a sud d en, fairly
loud inflation
noise will b e heard and some smoke will b e released . These oc c ur-
renc es are normal result of the d ep loyment. This sm oke d oes not ind i-
c ate a fire in the vehic le.
The SRS sid e airb ag is d esig ned to d ep loy in the ev ent of an ac c id ent
involving a mod erate to severe sid e imp ac t c ollisio n. It is b asic ally not
d esig ned to d ep loy in lesser sid e imp ac t imp ac ts b e c ause the nec es-
sary p rotec tion c an b e ac hieved b y the seatb elt alo ne. Also, it is b asi-
c ally not d esig ned to d ep loy in frontal or rear imp ac ts b ec ause SRS
sid e airb ag d ep loyment would not help the oc c up ant in those situa-
tions.
Eac h SRS sid e airb ag is d esig ned to func tion on a o ne-time-only b a-
sis.
SRS sid e airb ag d ep loyment d ep end s on the level of forc e exp eri-
enc ed in the p asseng er c omp artment d uring a sid e im p ac t c ollision.
That level d iffers from one typ e of c ollision to an other, and it may have
no b earing on the visib le d amag e d one to the vehic l e itself.

will most likely deploy.

SRS airbag system servicing
WARNING
When discarding an airbag module or scrapping the entire car
damaged by a collision, consult your SUBARU dealer. The SRS airbag has no user-serviceable parts. Do not use
electrical test equipment on any circuit related to the SRS airbag
system. For required servicing of the SRS airbag, see your near-
est SUBARU dealer. Tampering with or disconnecting the sys-
tem’ s wiring could result in accidental inflation of the SRS airbag
or could make the system inoperative, which may result in seri-
ous injury. The wiring harnesses of the SRS airbag system arecovered with yellow insulation and system connectors are yellowfor easy identification.
CAUTION
If you need service or repair in areas listed below, we recommend
that you have an authorized SUBARU dealer perform the work. The
SRS airbag control module, impact sensors and airbag modules
are stored in these areas.
Under the center console
Inside each front fender
Steering wheel and column and nearby areas
Top of the dashboard on front passenger ’s side and nearby
areas Each front seat and nearby area (only for vehicle with SRS
side airbags) Inside each center pillar

In the event that the SRS airbag is deployed, replacement of the sys-
tem should be performed only by an authorized SUBARU dealer.When the components of the SRS airbag system are replaced, useonly genuine SUBARU parts.
To ensure their long -term reliab ility, the SRS airb
ag s must b e insp ec ted
b y a SUBARU d ealer ten years after the d ate of manu fac ture, whic h is
shown on the c ertific ation lab el attac hed to the d r iver’s d oor.
NOTE In the following cases, contact your SUBARU dealer as soon as pos- sible. The front part of the vehicle was involved in an accident in
which the SRS frontal airbags did not deploy. The pad section of the steering wheel or front passenger ’s
frontal airbag cover is scratched, cracked, or otherwise damaged.
In addition, if your vehicle is equipped with SRS side airbags, con-tact your SUBARU dealer as soon as possible in the followingcases. Either center pillar or a nearby area of the vehicle was involved
in an accident in which the SRS side airbag did not deploy. The fabric or leather of either front seatback is cut, frayed, or
otherwise damaged.
Precautions against vehicle modification
WARNING
To avoid accidental activation of the system or rendering the
system inoperative, which may result in serious injury, no modifi-cations should be made to any components or wiring of the SRSairbag system.This includes following modifications: Installation of custom steering wheels
Attachment of additional trim materials to the dashboard
Installation of custom seats (only for vehicles with SRS side
