„Automatic/Emergency Locking Retrac- tor (A/ELR)
Each passenger’s seatbelt has an Automatic/Emer-
gency Locking Retractor (A/ELR). The Automatic/
Emergency Locking Retractor normally functions as
an Emergency Locking Retractor (ELR). The A/ELR
has an additional locking mode “Automatic Locking
Retractor (ALR) mode” intended to secure a child re-
straint system. When the seatbelt is once drawn out
completely and is then retracted even slightly, the re-
tractor locks the seatbelt in that position and the seat-
belt cannot be extended. As the belt is rewinding,
clicks will be heard which indicate the retractor func-
tions as an ALR. When the seatbelt is retracted fully,
the ALR mode is released.
When securing a child restraint system on the rear
seats by the use of the seatbelt, the seatbelt must be
changed over to the Automatic Locking Retractor (ALR) mode.
When the child restraint system is removed, make
sure that the seatbelt retracts fully and the retractor re-
turned to the Emergency Locking Retractor (ELR)
mode.
For instructions on how to convert the retractor to the
ALR mode and restore it to the ELR mode, see the
“Child restraint systems” section in this chapter. „
Seatbelt warning light and chime
Your vehicle is equipped with a seatbelt warning de-
vice at the driver’s seat, as required by current safety
standards.
This device causes the seatbelt warning light on the
instrument panel to light up when the ignition switch is
turned to “ON” to remind the driver to wear the seat-
belt. If the driver’s seatbelt is not fastened, the warning
light remains on and a warning chime sounds at the
same time. The warning light stays illuminated until
the driver fastens the seatbelt but the chime stops
sounding after about six seconds. „ Fastening the seatbelt
yNever use a belt that is twisted or reversed. In
an accident, this can increase the risk or sever-
ity of injury. y Keep the lap belt as low as possible on your
hips. In a collision, this spreads the force of the
lap belt over stronger hip bones instead of
across the weaker abdomen.y Seatbelts provide maximum restraint when
the occupant sits well back and upright in the
seat. To reduce the risk of sliding under the

yIf the front seatbelt retractor assembly or sur-
rounding area has been damaged, contact your
SUBARU dealer as soon as possible. y When you sell your vehicle, we urge you to ex-
plain to the buyer that it has seatbelt pretension-
ers by alerting him to the contents of this section.
y To obtain maximum protection, the occu-
pants should sit in an upright position with
their seatbelts properly fastened. Refer to the “Seatbelts” section in this chapter.y Do not modify, remove or strike the front
seatbelt retractor assemblies or surrounding
area. This could result in accidental activation
of the seatbelt pretensioners or could make the
system inoperative, possibly resulting in seri-
ous injury. Seatbelt pretensioners have no
user-serviceable parts. For required servicing
of front seatbelt retractors equipped with seat-
belt pretensioners, see your nearest SUBARU
dealer.y When discarding front seatbelt retractor as-
semblies or scrapping the entire vehicle due to
collision damage or for other reasons, consult
your SUBARU dealer.
„ System monitors
A diagnostic system continually monitors the readi-
ness of the seatbelt pretensioner while the vehicle is
being driven. The seatbelt pretensioners share the
control module with the SRS airbag system. There-
fore, if any malfunction occurs in a seatbelt preten-
sioner, the SRS airbag system warning light will illumi-
nate. The SRS airbag system warning light will show
normal system operation by lighting for about 6 sec-
onds when the ignition key is turned to the “ON” posi-

Seat, seatbelt and SRS airbags
– CONTINUED –
The SRS airbag can function only when the ignition
switch is in the “ON” position.
If the front sub sensors inside the both front fenders
and the impact sensors in the airbag control module
detect a certain predetermined amount of force during
a frontal collision, the control module sends signals to
the frontal airbag modules instructing them to inflate
the SRS frontal airbags. Then both airbag modules
produce gas, which instantly inflates driver’s and pas-
senger’s SRS frontal airbags. After the deployment,
the SRS airbags immediately start to deflate so that
the driver’s vision is not obstructed. The time required
from detecting impact to the deflation of the SRS air-
bag after deployment is shorter than the blink of an
eye.
The front passenger’s SRS frontal airbag deploys to-
gether with driver’s SRS frontal airbag even when no
one occupies the front passenger’s seat.
Although it is highly unlikely that the SRS airbag would
activate in a non-accident situation, should it occur,
the SRS airbag will deflate quickly, not obscuring vi-
sion and will not interfere with the driver’s ability to
maintain control of the vehicle.
When the SRS airbag deploys, a sudden, fairly loud
inflation noise will be heard and some smoke will be released. These occurrences are normal result of the
deployment. This smoke does not indicate a fire in the
vehicle.
Do not touch the SRS airbag system compo-
nents around the steering wheel and dash-
board with bare hands right after deployment.
Doing so can cause burns because the compo-
nents can be very hot as a result of deployment.
The SRS frontal airbag is designed to deploy in the
event of an accident involving a moderate to severe
frontal collision. It is basically not designed to deploy
in lesser frontal impacts because the necessary pro-
tection can be achieved by the seatbelt alone. Also, it
is basically not designed to deploy in side or rear im-
pacts or in roll-over accidents because deployment of
the SRS frontal airbag would not help the occupant in
those situations. The SRS airbag is designed to func-
tion on a one-time-only basis.
SRS airbag deployment depends on the level of force
experienced in the passenger compartment during a
collision. That level differs from one type of collision to
another, and it may have no bearing on the visible

– CONTINUED –
The SRS side airbag is basically not designed to de-
ploy if the vehicle is involved in a frontal collision or is
struck from behind. Examples of such accidents are il-
lustrated.
1) First impact
2) Second impact
In an accident where the vehicle is struck from the side
more than once, the SRS side airbag deploys only once.
Example: In the case of a double side impact collision,
first with one vehicle and immediately followed by an-
other from the same direction, once the SRS side air-
bag is activated on the first impact, it will not be acti- vated on the second. „
SRS airbag system monitors
A diagnostic system continually monitors the readi-
ness of the SRS airbag system while the vehicle is be-
ing driven. The SRS airbag system warning light “AIR-
BAG” will show normal system operation by lighting for
about 6 seconds when the ignition key is turned to the
“ON” position.

The valet key fits only the ignition switch and driver’s
door lock. You can keep the trunk and glove box
locked when you leave your vehicle and valet key at a
parking facility.
Do not attach a large key holder or key case to
either key. If it banged against your knees while
you were driving, it could turn the ignitionswitch from the ON position to the ACC or OFF
position, thereby stopping the engine.
„ Key number
The key number is stamped on the metal plate at-
tached to the key set. Write down the key number and
keep it in another safe place, not in the vehicle. This
number is needed to make a replacement key if you
lose your key or lock it inside the vehicle.
Immobilizer (WRX-STi)
The immobilizer system is designed to prevent an un-
authorized person from starting the engine. Only keys
registered with your vehicle’s immobilizer system can
be used to operate your vehicle. Even if an unregis-
tered key fits into the ignition switch and can be turned
to the “START” position, the engine will automatically
stop after several seconds.
Each immobilizer key contains a transponder in which
the key’s ID code is stored. When a key is inserted into
the ignition switch and turned to the “ON” position, the
transponder transmits the key’s ID code to the immo-
bilizer system’s receiver. If the transmitted ID code
matches the ID code registered in the immobilizer sys-
tem, the system allows the engine to be started. Since
the ID code is transmitted and acted upon almost in-
stantly, the immobilizer system does not impede nor-
mal starting of the engine.
If the engine fails to start, pull out the key once before
trying again. (Refer to the “Ignition switch” section
[chapter 3].)
NOTE
To protect your vehicle from theft, please pay
close attention to the following security precau-tions:
