Seat, Seatbelt and SRS Airbags1
– CONTINUED –
The front impact 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.
The driver’s and front passenger’s SRS
frontal airbags use dual stage inflators.
The two inflators of each airbag are trig-
gered either sequentially or simultane-
ously, 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
airbag.▼ After deployment
After deployment, the SRS airbag immedi-
ately 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.
▼ Example of the type of accident
The driver’s SRS frontal airbag and front
passenger’s SRS frontal airbag are
designed 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
impacts
*1
 To deploy in most side or rear impacts
or in most rollover accidents
*2
*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
passenger compartment during a colli-
sion. 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.
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.

Seat, Seatbelt and SRS Airbags1
– CONTINUED –
▼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 colli-
sion, 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.
In a rollover, SRS curtain airbags on both
sides of the vehicle deploy between the
occupant and the side window and
supplement 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
window 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 inde-
pendently 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 inde-
pendently of the driver’s and front
passenger’s SRS frontal airbags in the
steering wheel and instrument panel.
For the locations of the sensors and
control modules, refer to "Components"
 P68.
▼ 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.
▼ Example of the type of accident
The SRS side airbag and SRS curtain
airbag are designed as follows:
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 com-
ponents 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.

Warning and Indicator Lights
138engine at the first safe opportunity and
contact your nearest SUBARU dealer
immediately.■ AT OIL TEMP Warning
Light (AT Models) If this light illuminates when the engine is
running, it may indicate that the transmis-
sion fluid temperature is too hot.
If the light illuminates while driving, imme-
diately stop the vehicle in a safe place and
let the engine idle until the warning light
turns off.■ Low Tire Pressure
Warning Light (If
Equipped)When the ignition switch is turned to the
“ON” position, the low tire pressure
warning light will illuminate for approxi-
mately 2 seconds to check that the tire
pressure monitoring system (TPMS) is
functioning properly. If there is no problem
and all tires are properly inflated, the light
will go out.
Each tire, including the spare (if provided),
should be checked monthly when cold
and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of
a different size than the size indicated on the vehicle placard or tire inflation pres-
sure label, you should determine the

proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illumi-
nates a low tire pressure telltale when one
or more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TP MS is not a substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain
correct tire pressure, even if under-infla-
tion has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is no t operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure tell-
tale. When the system detects a malfunc-
tion, the telltale will flash for approximately one minute and then remain continuously

illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the
malfunction indicator is illuminated, the
system may not be able to detect or signal
low tire pressure as intended. TPMS
malfunctions may occur for a variety of
reasons, including the installation of
replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from
functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS
to continue to function properly.
Should the warning light illuminate
steadily after blinking for approximately
one minute, have the system inspected by
your nearest SUBARU dealer as soon as
possible.
WARNING
If this light does not illuminate
briefly after the ig nition switch is
turned on or the light illuminates
steadily after blinking for approxi-
mately one minute, you should have
your Tire Pressure Monitoring Sys-
tem checked at a SUBARU dealer as
soon as possible.

Warning and Indicator Lights
139
Instruments and Controls3
– CONTINUED –
If this light illuminates while driving,
never brake suddenly. Instead, per-
form the following procedure. Oth-
erwise an accident involving
serious vehicle damage and serious
personal injury could occur.1) Keep driving straight ahead while
gradually reducing speed.2) Slowly pull off the road to a safe
place.If this light still illuminates while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose air rapidly. If you
have a flat tire, replace it with a
spare tire as soon as possible.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the Low tire pres-
sure warning light will illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possi-
ble for tire and sensor replacement
and/or system resetting. If the light
illuminates steadily after blinking
for approximately one minute,
promptly contact a SUBARU dealer
to have the system inspected.
CAUTION
The tire pressure monitoring sys-
tem is NOT a substitute for manu-
ally checking tire pressure. The tire
pressure should be checked period-
ically (at least monthly) using a tire
gauge. After any change to tire
pressure(s), the tire pressure moni-
toring system will not re-check tire
inflation pressures until the vehicle
is first driven mo re than 25 mph (40
km/h). After adjusting the tire pres-
sures, increase the vehicle speed to
at least 25 mph (40 km/h) to start the
TPMS re-checking of the tire infla-
tion pressures. If the tire pressures
are now above the severe low pres-
sure threshold, the low tire pres-
sure warning light should turn off a
few minutes later. Therefore, be
sure to install the specified size for
the front and rear tires.
