2011 SUBARU IMPREZA warning

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.
! 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. NOTE
The driver
’s SRS side airbag, SRS
curtain airbag and seatbelt preten-
sioner are not controlled by the
SUBARU advanced frontal airbag sys-tem. ! 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.
Observe the following precautions. Failure
to do so may prevent the SUBARU
advanced frontal airbag system from
functioning correctly or cause the system
to fail. .
Do not apply any strong impact to the
front passenger ’s seat such as by kicking.
. Do not spill liquid on the front passen-
ger ’s seat. If liquid is spilled, wipe it off
immediately. . Do not remove or disassemble the front
passenger ’s seat.
. Do not install any accessory (such as
an audio amplifier) other than a genuine
SUBARU accessory under the front pas-senger ’s seat.
. Do not place anything (shoes, umbrel-
la, etc.) under the front passenger ’s seat.
. The front passenger ’s seat must not be
used with the head restraint removed. . Do not leave any article including a
child restraint system on the front passen- ger ’s seat or the seatbelt tongue and
buckle engaged when you leave yourvehicle. . Do not place a magnet near the
seatbelt buckle and the seatbelt retractor.. Do not use front seats with their back-
ward-forward position and seatback not
being locked into place securely. If any of
them are not locked securely, adjust them
again. For adjusting procedure, refer to“ Front seats ”F 1-2.
If the seatbelt buckle switch and/or frontpassenger ’s occupant detection system
have failed, the SRS airbag system Seat, seatbelt and SRS airbags

system inspected by your SUBARU deal-
er immediately 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. NOTE
The front passenger ’s SRS side airbag,
SRS curtain airbag and seatbelt pre-
tensioner are not controlled by the
SUBARU advanced frontal airbag sys-tem. ! Passenger ’s frontal airbag ON and
OFF indicators
Refer to “Front passenger ’s frontal airbag
ON and OFF indicators ”F 3-16.
! 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 a rearward
facing child restraint system and an infant
is restrained with it. (See WARNING that follows.) .
The seat is equipped with a forward
facing child restraint system and a small
child is restrained with it. (See WARNING
that follows.) . The seat is equipped with a booster
seat and a small child is in the booster
seat. (See WARNING that follows.) . The seat is relieved of the occupant
load for a time exceeding the predeter-
mined monitoring time period. . The seat is occupied by a child who
has outgrown a child restraint system
(See WARNING that follows.) or by a
small adult. . The front passenger ’s occupant detec-
tion system is malfunctioning.
WARNING
NEVER INSTALL A REARWARD FA-
CING CHILD SEAT IN THE FRONT
PASSENGER ’S 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 frontpassenger
’s seat may be killed or
severely injured should the frontpassenger ’s SRS frontal airbag de-
ploy. REAR seats are the safest
place for children.
When the front passenger ’s seat is occu-
pied by a child, observe the following
precautions. Failure to do so may increase
the load on the front passenger ’s seat,
activating the front passenger ’sSRS
frontal airbag even though that seat is
occupied by a child. . Do not place any article on the seat
other than the child occupant and a child
restraint system. . Do not place more than one child on
the seat.. Do not install any accessory such as a
table or TV onto the seatback.. Do not store a heavy load in the
seatback pocket.. Do not allow the rear seat occupant to
place his/her hands or legs on the front passenger ’s seatback, or allow him/her to
pull the seatback.

!Examples of the types of accidents
in which the driver ’s/driver ’s and
front passenger ’s SRS frontal
airbag(s) will basically not deploy.
The driver ’s and front passenger ’s SRS
frontal airbags are designed basically not to deploy if the vehicle is struck from the
side or from behind, or if it rolls onto its
side or roof, or if it is involved in a low-
speed frontal collision.
1) First impact
2) 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 firstimpact.
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
The SRS side airbag is stored in the door
side of each front seat seatback, which
bears an “SRS AIRBAG ”label.
Inamoderatetoseveresideimpact
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.
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.
Inamoderatetoseveresideimpact
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.
WARNING
The SRS side airbag and SRS
curtain airbag are designed as only
a supplement to the primary protec-
tion provided by the seatbelt. They Seat, seatbelt and SRS airbags

1-50Seat, seatbelt and SRS airbags
do 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 is not seated in a proper
upright position.
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.
WARNING
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.

WARNING
. Never allow a child to kneel on
the front passenger ’s seat facing
the side window or to wrap his/
her arms around the front seat
seatback. In the event of an
accident, the force of the SRS
side airbag deployment could
injure the child seriously be-
cause his/her head or arms or
other parts of the body are too
close to the SRS side 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.
. Never allow a child to kneel on
any passenger ’s seat facing the
side window or put their head,
arms and hands out of the win-
dow. In the event of an accident,
the force of the SRS curtain
airbag deployment could injure
the child seriously because his/
her head is close to the SRS
curtain airbag.
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 be pro-
pelled dangerously toward thevehicle ’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.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.
! Operation
The SRS side airbag and SRS curtain
airbag can function only when the ignition
switch is in the “ON ”position.
The driver ’s and front passenger ’s SRS
side airbags and SRS curtain airbags deploy independently of each other since
each has its own impact sensor. There-
fore, they may not both deploy in the same
accident. Also, the SRS side airbag and
SRS curtain airbag deploys independently
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 left and
right center pillars and rear wheel houses.
Another impact sensor, which also senses
impact force, is located under the rear
center seat. If one of the center pillar
impact sensors and the impact sensor that
is located under the rear center seat
together sense an impact force above a
predetermined level in a side collision, the
control module causes both the SRS side
airbag and curtain airbag on the impacted
side to inflate regardless of whether the
rear wheel house impact sensor on the
same side senses an impact. If one of the
rear wheel house impact sensors and the
impact sensor that is located under the
rear center seat together sense an impact
force above a predetermined level, the
control module causes only the SRS
curtain airbag on the impacted side toinflate.
After the deployment, the SRS side airbag
