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 air-
bag are 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
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 im-
pact 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 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 “AIRBAG” will
show normal system operation by lighting
for approximately 6 seconds when the ig-
nition switch is turned to the “ON” position.
The following components are monitored
by the indicator: y Front sub sensor (Right-hand side)

If the warning light exhibits any of
the following conditions, there may
be a malfunction in the seatbelt pre-
tensioners and/or SRS airbag sys-
tem. Immediately take your vehicle
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 mi-
nor collision or not inflate in a se-
vere collision), which may increase
the risk of injury.
yFlashing or flickering of the warn-
ing light
yNo illumination of the warning
light when the ignition switch is first turned to the “ON” position
yContinuous illumination of the
warning light
yIllumination of the warning light
while driving
yWhen discarding an airbag mod-
ule or scrapping the entire vehicle
damaged by a collision, consult
your SUBARU dealer.
yThe SRS airbag has no user-ser-
viceable parts. Do not use electri-
cal 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 discon-
necting the system’s wiring could
result in accidental inflation of the
SRS airbag or could make the sys-
tem inoperative, which may result
in serious injury. The wiring har-
nesses of the SRS airbag system
are covered with yellow insulation
and system connectors are yellow
for easy identification.

In the event that the SRS airbag is de-
ployed, replacement of the system
should be performed only by an autho-
rized SUBARU dealer. When the com-
ponents of the SRS airbag system are
replaced, use only genuine SUBARU parts.
NOTE
In the following cases, contact your
SUBARU dealer as soon as possible. y
The front part of the vehicle was in-
volved in an accident in which the only
the driver’s SRS frontal airbag or both
driver’s and front passenger’s SRS
frontal airbags did not deploy.y The pad of the steering wheel, the
cover over the front passenger’s SRS
frontal airbag, or either roof side (from
the front pillar to a point over the rear
seat) is scratched, cracked, or other-
wise damaged.y Either center pillar and rear wheel
house or a nearby area of the vehicle
was involved in an accident in which
the SRS side airbag and SRS curtain
airbag did not deploy. y The fabric or leather of either front
seatback is cut, frayed, or otherwise
damaged. „

TDisarming 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. Al-
so, the number of flashes indicates the lo-
cation of unauthorized intrusion or the se-
verity of impact on the vehicle.y When the ignition switch is turned to the
“ON” position, the indicator light will light
for 1 second and then flash as follows:
When a door or rear gate (Station wag-
on) was opened: 5 times
When the trunk (Sedan) was opened: 4times
When a strong impact or multiple im-
pacts were sensed: twice (only vehicles
with shock sensors (dealer option))
When a light impact was sensed: once
(only vehicles with shock sensors (deal-
er option))
„ Shock sensors (dealer op- tion)
The shock sensors trigger the alarm sys-
tem when they sense impacts applied to
the vehicle and when any of their electric
wires is cut. The alarm system causes the
horn to sound and the turn signal lights to flash for a short time when the sensed im-
pact is weak, but it warns of a strong im-
pact or multiple impacts by sounding the
horn and flashing the turn signal lights,
both lasting approximately 30 seconds.
If you desire, your SUBARU dealer can
connect them and set them for activation
or deactivation.
NOTE y
The shock sensors are not always
able to sense impacts caused by
breaking in, and cannot sense an im-
pact that does not cause vibration
(such as breaking the glass using a
rescue hammer).y The shock sensors may sense vibra-
tion like those shown in the following
and trigger the alarm system. Select
the settings of the alarm system and
shock sensors appropriately depend-
ing on where you usually park your ve-hicle.
Example:
Vibration from construction site
Vibration in multistory car park
Vibration from trains
y You can have the sensitivity of the
shock sensors adjusted to your prefer-
ence by your SUBARU dealer.
Child safety locks
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.
Always use the child safety lock
whenever a child rides in the rear
seat. Serious injury could result if a
child accidentally opened the door
and fell out.

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 rec-
ommended by the vehicle manufacturer
on the vehicle placard or tire inflation pres-
sure 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 prop-
er inflation pressure for those tires.) As an
added safety feature, your vehicle has
been equipped with a tire pressure moni-
toring system (TPMS)
that illuminates 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. Driv-
ing 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 TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to main-
tain correct tire pre ssure, even if under-in- flation has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.
The TPMS gives warning both when a tire
is significantly under-inflated and when
there is a problem in the TPMS. The low
tire pressure warning light operates differ-
ently according to these conditions as fol-
lows:
When a tire is significantly under-inflat-
ed:
Steady illumination
When there is a problem in the TPMS:
Flashing
Should the warning light flash, have the
system inspected by your nearest
SUBARU dealer as soon as possible.
If this light does not come on briefly
after the ignition switch is turned
ON or the light is flashing, you
should have your Tire Pressure
Monitoring System checked at a
SUBARU dealer as soon as possi-
ble.
If this light comes on while driving,
never brake suddenly and keep driv-
ing straight ahead while gradually
reducing speed. Then slowly pull off
the road to a safe place. Otherwise
an accident involving serious vehi-
cle damage and serious personal in-
jury could occur.
If this light still comes on while driv-
ing after adjusting the tire pressure,
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 flash. This in-
dicates the TPMS is unable to moni-
tor all four road wheels. Contact
your SUBARU dealer as soon as
possible for tire and sensor replace-
ment and/or system resetting. If the
light flashes, promptly contact a SUBARU dealer to have the system
inspected.

Mirrors
Always check that the inside and outside
mirrors are properly adjusted before you
start driving. „Inside mirror
The inside mirror has a day and night po-
sition. Pull the tab at the bottom of the mir- ror toward you for t he night position. Push
it away for the day position. The night po-
sition reduces glare from headlights. „
Auto-dimming mirror/com-
pass (if equipped)
1) Left button
2) Auto dimming indicator
3) Photosensor
4) Right button
The auto-dimming mirror/compass has an
anti-glare feature which automatically re-
duces glare coming from headlights of ve-
hicles behind you. It also contains a built-
in compass. y By pressing and releasing the left but-
ton, the automatic dimm ing function is tog-
gled on or off. When the automatic dim-
ming function is on, the auto dimming indi-
cator light (green) located to the right of
the button will illuminate. y By pressing and releasing the right but- ton, the compass display is toggled on or
off. When the compass is on, an illuminat-
ed compass reading will appear in the
lower part of the mirror.
Even with the mirror in anti-glare mode,
the mirror surface turns bright if the trans-
mission is shifted into reverse. This is to
ensure good rearward visibility during re- versing. T
Photosensors
The mirror has a photosensor attached on
both the front and back sides. If the glare
from the headlights of vehicles behind you
strikes the mirror, these sensors detect it
and make the reflection surface of the mir-
ror dimmer to help prevent you from being
blinded. For this reason, use care not to

cover the sensors with
stickers, or other
similar items. Periodically wipe the sen-
sors clean using a piece of dry soft cotton
cloth or an applicator. T Compass calibration
1. For optimum calibration, switch off all
nonessential electrical accessories (rear
window defogger, heater/air conditioning system, spotlight , etc.) and ensure all
doors are shut.
2. Drive to an open, level area away from
large metallic objects or structures and
make certain the ignition switch is in the
“ON” position.
3. Press and hold the left button for 3 sec-
onds then release, and the compass will
enter the calibration mode. “CAL” and di-
rection will be displayed.
4. Drive slowly in a circle until “CAL” dis-
appears from the di splay (approximately
two or three circles). The compass is now
calibrated.
5. Further calibration may be necessary
should outside influences cause the mirror
to read inaccurately. You will know that
this has occurred if your compass begins
to read in only limited directions. Should
you encounter this situation, return to step
one of the above procedure and recali-brate the mirror. T
Compass zone adjustment
1. The zone setting is factory preset to
Zone 8. Refer to the “Compass calibration
zone” map attached to the end of this
manual to verify that the compass zone
setting is correct for your geographical lo- cation.
2. Press and hold the right button for 3
seconds then release, and the word
“ZONE” will briefly appear and then the
zone number will be displayed.
3. Press the right-hand button repeatedly to cycle the display through all possible
zone settings. Stop cycling when the cor- rect zone setting for your location is dis-
played.
4. Releasing the button for 3 seconds will
exit the zone setting mode. „

NOTE
When driving on a dusty road or be-
hind a vehicle that emits unpleasant
exhaust gases, set the air inlet selec-
tion button to the “ ” position. From time to time, return the air inlet
selection button to the “ ” posi-
tion to draw outsid e air into the pas-
senger compartment. „
Temperature sensors
1) Solar sensor
2) Interior air temperature sensor
The automatic climate control system em-
ploys several sensors. These sensors are
delicate. If they are treated incorrectly and
become damaged, the system may not be
able to control the interior temperature
correctly. To avoid damaging the sensors,
observe the following precautions:
– Do not subject the sensors to impact.
– Keep water away from the sensors.
– Do not cover the sensors.
The sensors are located as follows:
– Solar sensor: beside windshield de-
froster grille
– Interior air temperature sensor: on the side of the driver-si
de part of the center
panel
– Outside temperature sensor: behind
front grille.
Continued operation in the “ ”
position may fog up the windows.
Switch to the “ ” position as
soon as the outside dusty condition
clears.
