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.
. Do not hang coat hangers or
other hard or pointed objects on
the coat hooks. If such items
were hanging on the coat hooks
during deployment of the SRS
curtain airbags, they could cause
serious injuries by coming off the
coat hooks and being thrown
through the cabin or by prevent-
ing deployment of the curtainairbags. 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. !
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 in the airbag
control module.
If one of the center pillar impact sensors
and the impact sensor that is located in
the airbag control module 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 in the airbag control module
together sense a sufficiently strong impact
force, the control module causes only the
SRS curtain airbag on the impacted side
to inflate.
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 occupiesthe seat on the side on which an impact isapplied.
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 ofdeployment.
After deployment, do not touch any
part of the SRS curtain airbag
system (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.
The SRS side airbag and SRS curtain
airbag are designed to deploy in the event
of an accident involving a moderate to
severe side impact collision. It is basically
not designed to deploy in a lesser side impact. Also, it is basically not designed to
deploy in frontal or rear impacts because
SRS side airbag and SRS curtain airbag
deployment would not help the occupant
in those situations.
Each SRS side airbag and SRS curtain
airbag are designed to function on a one-
time-only basis.
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 vehicleitself.

! Examples of the types of accidents
in which the SRS side airbag and
SRS curtain airbag will basically not
deploy.
1) The vehicle is involved in frontal collision
with another vehicle (moving or station- ary). 2) The vehicle is struck from behind.
The SRS side airbag and SRS curtain
airbag are basically not designed to
deploy if the vehicle is involved in a frontal
collision or is struck from behind. Exam-
ples of such accidents are illustrated.
1) First impact
2) Second impact
A) SRS curtain airbag
B) SRS side airbag
In an accident where the vehicle is struck
from the side more than once, the SRS
side airbag and SRS curtain airbag deploy
only once on the first impact.
Example: In the case of a double side
impact collision, first with one vehicle and
immediately followed by another from the
same direction, once the SRS side airbag and SRS curtain airbag are activated on
the first impact, they will not be activated
on the second.
& SRS airbag system monitorsA diagnostic system continually monitors
the readiness of the SRS airbag system
(including front seatbelt pretensioners)
while the vehicle is being driven. The
SRS airbag system warning light “AIR-
BAG ”will show normal system operation
by lighting for approximately 6 seconds
when the ignition switch is turned to the“ ON ”position.
The following components are monitored
by the indicator. . Front sub sensor (right-hand side)

WARNING
If the warning light exhibits any of
the following conditions, there may
be a malfunction in the seatbelt
pretensioners and/or SRS airbag
system. Immediately take your vehi-
cle to your nearest SUBARU dealer
to have the system checked. Unless
checked and properly repaired, the
seatbelt pretensioners and/or SRS
airbags will operate improperly (e.g.
SRS airbags may inflate in a very
minor collision or not inflate in a
severe collision), which may in-
crease the risk of injury. . Flashing or flickering of the warn-
ing light
. No illumination of the warning
light when the ignition switch is
first turned to the “ON ”position
. Continuous illumination of the
warning light
. Illumination of the warning light
while driving &
SRS airbag system servicingWARNING
. When discarding an airbag mod-
ule or scrapping the entire vehi-
cle damaged by a collision, con-
sult 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, consult your
nearest SUBARU dealer. Tamper-
ing with or disconnecting the system ’s wiring could result in
accidental inflation of the SRS
airbag or could make the system
inoperative, which may result in
serious injury.

Alarm system
The alarm system helps to protect your
vehicle and valuables from theft. The horn
sounds and the turn signal lights flash if
someone attempts to break into yourvehicle.
The system can be armed and disarmed
with the remote transmitter.
The system does not operate when the
key is inserted into the ignition switch.
Your vehicle ’s alarm system has been set
for activation at the time of shipment from
the factory. You can set the system for
deactivation yourself or have it done by
your SUBARU dealer. & System alarm operation
The alarm system will give the following
alarms when triggered: . The vehicle ’s horn will sound and the
turn signal lights will flash for 30 seconds.. If any door (or the rear gate/trunk lid)
remains open after the 30-second period,
the horn will continue to sound for a
maximum of 3 minutes. If the door (or
the rear gate/trunk lid) is closed while the
horn is sounding, the horn will stop
sounding with a delay of up to 30 seconds. The alarm is triggered by: .
Opening a door, the rear gate or trunk
lid. Physical impact to the vehicle, such as
forced entry (only models with shock
sensors (dealer option))
NOTE
The alarm system can be set to trigger
illumination of map lights and dome
light. The map lights and dome light
notification is deactivated as the fac-
tory setting. Refer to “Function set-
tings ”F20. A SUBARU dealer can
activate the system. Contact your
SUBARU dealer for details. & Activating and deactivating
the alarm system
To change the setting of your vehicle ’s
alarm system for activation or deactiva-
tion, do the following.
1. Disarm the alarm system. Refer to “ Disarming the system ”F 2-18.
2. Sit in the driver ’s seat and shut all
doors (and the rear gate (Outback)).
3. Turn the ignition switch to the “ON ”
position.
4. Hold down the REAR (UNLOCK) side
of the driver ’s power door locking switch,
open the driver ’s door within the following 1 second, and wait 10 seconds without
releasing the switch. The setting will then
be changed as follows:
If the system was previously activated:
The trip meter screen displays
“AL oF ”
and the horn sounds twice, indicating that
the system is now deactivated.
If the system was previously deacti- vated:
The trip meter screen displays “AL on ”and
the horn sounds once, indicating that the
system is now activated.
NOTE
You may have the above setting
change done by your SUBARU dealer. & If you have accidentally trig-
gered the alarm system
! To stop the alarm
Perform any of the following operations. . Press any button on the remote trans-
mitter.. Turn the ignition switch to the “ON ”
position.

!Arming the system
CAUTION
In passive mode, the system will
automatically activate the alarm but
WILL NOT automatically lock the
doors. In order to lock the doors
you must either lock them as in-
dicated in step 4 below or with the
key once they have been closed.
Failure to lock the doors manually
will result in a higher security risk.
1. Turn the ignition switch to the “ON ”
position.
1) LOCK
2) ON
2. Turn the ignition switch from “ON ”to “
LOCK ”position and remove the key from
the ignition switch.
3. Open the doors and get out of the vehicle.
4. Before closing the doors, lock all doors
with the inside door lock levers.
5. Close the doors. The system will
automatically arm after 1 minute.
In the passive mode, the system can also
be armed with the remote transmitter or
with the power door locking switches. If
the remote transmitter or power door
locking switch is used to lock the vehicle,
arming will take place immediately regard-
less of whether or not the passive mode
has been selected. !
Disarming the system
To disarm the system, briefly press the “
” button on the transmitter.
& Tripped sensor identification
The security indicator light flashes when
the alarm system has been triggered.
Also, the number of flashes indicates the
location of unauthorized intrusion or the
severity of impact on the vehicle.
When the ignition switch is turned to the “ ON ”position, the indicator light will
illuminate for 1 second and then flash asfollows: . When a door or rear gate (Outback)
was opened: 5 times. When the trunk (Legacy) was opened:
4 times . When a strong impact or multiple
impacts were sensed: twice (only models
with shock sensors (dealer option)) . When a light impact was sensed: once
(only models with shock sensors (dealer option)) & Shock sensors (dealer op- tion)
The shock sensors trigger the alarm
system when they sense impacts applied
to the vehicle and when any of their
electric wires is cut. The alarm system Keys and doors

2-20Keys and doors
causes the horn to sound and the turn
signal lights to flash for a short time when
the sensed impact is weak, but it warns of
a strong impact or multiple impacts by
sounding the horn and flashing the turn
signal lights, both lasting approximately 30seconds.
If you desire, your SUBARU dealer can
connect them and set them for activation
or deactivation. NOTE .The shock sensors are not always
able to sense impacts caused by break-
ing in, and cannot sense an impact that
does not cause vibration (such as
breaking the glass using a rescuehammer).. The shock sensors may sense vi-
bration like those shown in the follow-
ing and trigger the alarm system.
Select the settings of the alarm system
and shock sensors appropriately de-
pending on where you usually park
your vehicle.Examples:
–Vibration from construction site
– Vibration in multistory car park
– Vibration from trains
. You can have the sensitivity of the
shock sensors adjusted to your pre-
ference by your SUBARU dealer. Child safety locks
WARNING
Always turn the child safety locks to the “LOCK ”position when children
sit on the rear seat. Serious injury
could result if a child accidentally
opens the door and falls out.
Each rear door has a child safety lock that
prevents the doors from being opened
even if the inside door handle is pulled.
When the child safety lock lever is in the “ LOCK ”position, the door cannot be
opened from inside regardless of the
position of the inner door handle lock
lever. The door can only be opened from the outside.
