1-54Seat, seatbelt and SRS airbags
! Examples of the types of accidents in which the SRS side airbag is unlikely to
deploy.
1) The vehicle is involved in an oblique
side-on impact.
2) The vehicle is involved in a side-on impact in an area outside the vicinity of
the passenger compartment.
3) The vehicle strikes a telephone pole or similar object.
4) The vehicle is involved in a side-on impact from a motorcycle.
5) The vehicle rolls onto its side or roof.
There are many types of collisions which
might not necessarily require SRS side
airbag deployment. In the event of acci-
dents like those illustrated, the SRS side
airbag may not deploy depending on the
level of accident forces involved.

!Examples of the types of accidents
in which the SRS side airbag will
basically not deploy.
1) The vehicle is involved in a frontal
collision with another vehicle (moving or stationary).
2) The vehicle is struck from behind. The SRS side airbag is basically not
designed to deploy if the vehicle is
involved in a frontal collision or is struck
from behind. Examples of such accidents
are illustrated.
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 on the firstimpact.
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
is activated on the first impact, it will not be
activated on the second. &
SRS airbag system monitors
A 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)

Seatbelt warning light
and chime
Your vehicle is equipped with a seatbelt
warning device at the driver ’s seat, as
required by current safety standards.
There is a seatbelt warning light in the
combination meter.
If the driver has not yet fastened the
seatbelt when the ignition switch is turned
to the “ON ”position, the seatbelt warning
light will flash for 6 seconds, to warn that
the seatbelt is unfastened. If the driver ’s
seatbelt is not fastened, a chime will also
sound simultaneously.
If the driver ’s seatbelt is still not fastened 6
seconds later, the warning light will remain
lit for 15 seconds. If the driver ’s seatbelt is
still not fastened even 15 seconds later
(21 seconds after turning ON the ignition
switch), the warning lights will alternate
between flashing and steady illumination
at 15-second intervals, and the chime will
sound while the warning light is flashing.
Alternate flashing and steady illumination
of the warning lights and sounding of the
chime will continue until the driver fastens
the seatbelt. NOTE .
If the driver unfastens the seatbelt
after fastening, the seatbelt warning
device operates as follows according
to the vehicle speed.
.At speeds lower than approxi-
mately 9 mph (15 km/h)
The warning light will alternate
between flashing and steady illumi-
nation at 15-second intervals. The
chime will not sound. . At speeds higher than approxi-
mately 9 mph (15 km/h)
The warning light will alternate
between flashing and steady illumi-
nation at 15-second intervals and
the chime will sound while the

. It is possible to cancel the warning
operation that follows the 6-second
warning after turning ON the ignition
switch. When the ignition switch is
turned ON next time, however, the
complete sequence of the warning
operation resumes. For further details
about canceling the warning operation,
please contact your SUBARU dealer. & SRS airbag system
warning light
When the ignition switch is turned to the

“ON ”position, the SRS airbag system
warning light will come on for approxi-
mately 6 seconds and go out. This shows
the SRS airbag and SRS side airbag (if
equipped) and seatbelt pretensioners are
in normal operation.
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
airbag will not operate properly in
the event of a collision, which may
increase 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

Front passenger ’s frontal
airbag ON and OFF indica- tors
ON or: Front passenger ’s frontal airbag ON
indicator
or: Front passenger ’s frontal airbag
OFF indicator
The front passenger ’s frontal airbag ON
and OFF indicators show you the status of
the front passenger ’s SRS frontal airbag.
The indicators are located next to the
clock in the center portion of the dash-board.
When the ignition switch is turned to the “ ON ”position, both the ON and OFF
indicators illuminate for 6 seconds during
which time the system is checked. Follow-
ing the system check, both indicators extinguish for 2 seconds. After that, one
of the indicators illuminates depending on
the status of the front passenger
’s SRS
frontal airbag determined by the Subaru
advanced frontal airbag system monitor-ing.
If the front passenger ’s SRS frontal airbag
is activated, the passenger ’s frontal airbag
ON indicator will illuminate while the OFF
indicator will remain extinguished.
If the front passenger ’s SRS frontal airbag
is deactivated, the passenger ’s frontal
airbag ON indicator will remain extin-
guished while the OFF indicator willilluminate.
With the ignition switch turned to the “ON ”
position, if both the ON and OFF indica-
tors remain lit or extinguished simulta-
neously even after the system check
period, the system is faulty. Contact your
SUBARU dealer immediately for an in-spection. Instruments and controls

&CHECK ENGINE warn-
ing light/Malfunction in-
dicator lamp
CAUTION
If the CHECK ENGINE light comes
on while you are driving, have your
vehicle checked/repaired by your
SUBARU dealer as soon as possi-
ble. Continued vehicle operation
without having the emission control
system checked and repaired as
necessary could cause serious da-
mage, which may not be covered by
your vehicle ’s warranty.
If this light comes on steadily or blinks
while the engine is running, it may indicate
that there is a problem or potential
problem somewhere in the emission con-
trol system. ! If the light comes on steadily:
If the light comes on steadily while driving
or does not go out after the engine starts,
an emission control system malfunction
has been detected.
You should have your vehicle checked by
an authorized SUBARU dealer immedi-
ately. NOTE
This light also comes on when the fuel
filler cap is not tightened until it clicks.
If you have recently refueled your vehicle,
the cause of the CHECK ENGINE warning
light/malfunction indicator lamp coming on
could be a loose or missing fuel filler cap.
Remove the cap and retighten it until it
clicks. Make sure nothing is interfering
with the sealing of the cap. Tightening the
cap will not make the CHECK ENGINE
warning light turn off immediately. It may
take several driving trips. If the light does
not go out, take your vehicle to your
authorized SUBARU dealer immediately. !
If the light is blinking:
If the light is blinking while driving, an
engine misfire condition has been de-
tected which may damage the emission
control system.
To prevent serious damage to the emis-
sion control system, you should do thefollowing. . Reduce vehicle speed.
. Avoid hard acceleration.
. Avoid steep uphill grades.
. Reduce the amount of cargo, if possi-
ble.. Stop towing a trailer as soon as
possible. The CHECK ENGINE warning light may
stop blinking and come on steadily after
several driving trips. You should have your
vehicle checked by an authorized
SUBARU dealer immediately. &
Charge warning light
If this light comes on when the engine is
running, it may indicate that the charging
system is not working properly.
If the light comes on while driving or does
not go out after the engine starts, stop the
engine at the first safe opportunity and
check the alternator belt. If the belt is
loose, broken or if the belt is in good
condition but the light remains on, contact
