!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 for about six seconds
when the ignition switch is turned to “ON” to remind the
driver to wear the seatbelt. If the driver’s seatbelt is not
fastened, a warning chime sounds at the same time. ! Fastening the seatbelt
"Never use a belt that is twisted or reversed. In
an accident, this can increase the risk or sever-
ity of injury. " 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. " Seatbelts provide maximum restraint when
the occupant sits well back and upright in the
seat. To reduce the risk of sliding under the
seatbelt in a collision, the front seatbacks
should be always used in the upright position
while the vehicle is running. If the front seat-

! 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- tion.
The following components are monitored by the indi- cator:"
Front sub sensor (Right hand side)
" Front sub sensor (Left hand side)
" Airbag control module (including impact sensors)
" Seatbelt pretensioner (driver’s side)
" Seatbelt pretensioner (Passenger’s side)
" All related wiring
" And all other airbag components
In the event of a malfunction indicated by any of follow-
ing, the vehicle should be taken promptly to your near-
est SUBARU dealer to have the system checked. Un-
less checked and repaired, the seatbelt pretensioners
and SRS airbag will not function reliably: " Flashing or flickering of the indicator light.
" No illumination of the warning light when the ignition
switch is first turned to the “ON” position." Continuous illumination of the warning light.

Seat, seatbelt and SRS airbags
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 following components are monitored by the indi- cator:" Front sub sensor (Right hand side)

SRS airbag system servicing
"When discarding an airbag module or scrap-
ping the entire car 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, see
your nearest SUBARU dealer. Tampering with
or disconnecting the system’s wiring could re-
sult in accidental inflation of the SRS airbag or
could make the system inoperative, which may
result in serious injury. The wiring harnesses of
the SRS airbag system are covered with yellow
insulation and system connectors are yellow
for easy identification.
If you need service or repair in areas listed be-
low, we recommend that you have an autho-
rized SUBARU dealer perform the work. The
SRS airbag control module, impact sensors
and airbag modules are stored in these areas.

alarm levels for shock: warning and alarm. In warning
mode, the alarm detects lower level vibrations and
triggers 2 warning chirps on the horn and two flashes
on the lights as a deterrent to would be vandals. In
alarm mode, higher levels of shock are detected and
the system will go into full alarm. "Ignition switch being turned on while in armed state.
NOTE
With the valet mode selected, the security system
does not operate when the remote transmitter is
used for locking and unlocking. The security sys-
tem indicator light in the combination meter flash-
es twice per second to show that the valet mode is
selected. For details, refer to “Valet mode” in this
section. ! Arming the system
! To arm the system using remote transmitter
1. Close all windows.
2. Remove the key from the ignition switch.
3. Open the doors and get out of the vehicle.
4. Make sure that the engine hood (and the trunk lid)
are locked.
5. Close all doors (and the rear gate on the wagon). 1) Press to Arm the system.
