1-52Seat, seatbelt and SRS airbags
event of the SRS side airbag deploy-
ment, they could be propelled dan-
gerously toward the vehicle ’s occu-
pants and cause injuries.
WARNING
Do not put any kind of cover or
clothes or other objects over either
front seatback and do not attach
labels or stickers to the front seat
surface on or near the SRS side
airbag. They could prevent proper
deployment of the SRS side airbag,
reducing protection available to the
front seat ’s occupant. !
Operation
1) SRS side airbag deploys as soon as a
collision occurs.
2) SRS side airbag protects the front passenger ’s head and chest.
3) After deployment, SRS side airbag starts to deflate immediately. The SRS side airbag can function only
when the ignition switch is in the
“ON ”
position.
The driver ’s and front passenger ’s SRS
side airbags deploy independently of each
other since each has its own impact
sensor. Also, the SRS side airbag deploys
independently of the frontal airbags in the
steering wheel and instrument panel.
An impact sensor is incorporated into
each of the vehicle ’s center pillars. If
either sensor detects a certain predeter-
mined amount of force during a side
impact collision, the control module sends
a signal to the side airbag module on the
impacted side of the vehicle, instructing it
to inflate the SRS side airbag. Then the
side airbag module produces gas, which
instantly inflates the SRS side airbag.
After deployment, the SRS side airbag
will deflate in a few seconds.
The SRS side airbag deploys even when
no one occupies the seat on the side on
which an impact is applied.
When the SRS side 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.

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. .

warning light
. Illumination of the warning light
while driving
& SRS airbag system servicing
WARNING
. When discarding an airbag mod-
ule or scrapping the entire vehi-
cle 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 result in accidental
inflation of the SRS airbag or
could make the system inopera-
tive, which may result in serious
injury. The wiring harnesses of
the SRS airbag system are cov-
ered with yellow insulation and
system connectors are yellow for
easy identification.

In the event that the SRS airbag is
deployed, replacement of the system
should be performed only by an author-
ized SUBARU dealer. When the compo-
nents of the SRS airbag system are
replaced, use only genuine SUBARUparts.
To ensure their long-term reliability, the
SRS airbags must be inspected by a
SUBARU dealer ten years after the date
of manufacture, which is shown on the
certification plate attached to the driver ’s
doorjamb. NOTE
In the following cases, contact your
SUBARU dealer as soon as possible. . The front part of the vehicle was
involved in an accident in which only
the driver ’s SRS frontal airbag or both
driver ’s and front passenger ’sSRS
frontal airbags did not deploy.. The pad section of the steering
wheel or front passenger ’s frontal air-
bag cover is scratched, cracked, or
otherwise damaged.
In addition, if your vehicle is equipped
with SRS side airbags, contact your
SUBARU dealer as soon as possible in the following cases. .

Ignition switch
WARNING
. Never turn the ignition switch to
“ LOCK ”while the vehicle is
being driven or towed because
that will lock the steering wheel,
preventing steering control. And
when the engine is turned off, it
takes a much greater effort than
usual to steer.
. Before leaving the vehicle, al-
ways remove the key from the
ignition switch for safety and
never allow an unattended child
to remain in the vehicle. Failure
to follow this procedure could
result in injury to a child or
others. Children could operate
the power windows, the moon-
roof or other controls or even
make the vehicle move.
CAUTION
Do not attach a large key holder or
key case to either key. If it banged
against your knees or hands while
you are driving, it could turn the
ignition switch from the “ON ”posi- tion to the
“Acc ”or “LOCK ”posi-
tion, thereby stopping the engine.
Also, if the key is attached to a
keyholder or to a large bunch of
other keys, centrifugal force may act
on it as the vehicle moves, resulting
in unwanted turning of the ignitionswitch.
The ignition switch has four positions:
LOCK, Acc, ON and START. NOTE . Keep the ignition switch in the
“ LOCK ”position when the engine is
not running. . Using electrical accessories for a
long time with the ignition switch in the
"ON" or “Acc ”position can cause the battery to go dead..
If the ignition switch will not move
from the “LOCK ”position to the “Acc ”
position, turn the steering wheel
slightly to the left and right as you turn
the ignition switch. & LOCK
The key can only be inserted or removed
in this position. The ignition switch will lock
the steering wheel when you remove the
key.
If turning the key is difficult, turn the
steering wheel slightly to the right and left
as you turn the key. ! Automatic transmission vehicles

7-8Starting and operating
position without depressing the accelera-
tor pedal. Release the key immediately
after the engine has started.
If the engine does not start, try the following.
(1) Turn the ignition switch to the“OFF ”position and wait for at least
10 seconds. After checking that the
parking brake is firmly set, turn the
ignition switch to the “START ”position
while depressing the accelerator pedal
slightly (approximately a quarter of the
full stroke). Release the accelerator
pedal as soon as the engine starts.
(2) If this fails to start the engine, turn
the ignition switch back to the “OFF ”
position and wait for at least 10
seconds. Then fully depress the accel-
erator pedal and turn the ignition
switch to the “START ”position. If the
engine starts, quickly release the
accelerator pedal.
(3) If this fails to start the engine, turn
the ignition switch again to the “OFF ”
position. After waiting for 10 seconds
or longer, turn the ignition switch to the“ START ”position without depressing
the accelerator pedal.
(4) If the engine still refuses to start,
contact your nearest SUBARU dealer
for assistance. 6. Confirm that all warning and indicator
lights have gone out after the engine has
started. The fuel injection system auto-
matically lowers the idle speed as the
engine warms up.
While the engine is warming up, make
sure that the selector lever is at the
“P ”or
“ N ”position and that the parking brake is
applied.
NOTE
The engine may be difficult to start
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This diffi-
culty is caused by the electronically
controlled throttle ’s self-diagnosis
function. To overcome it, keep the
ignition switch in the “ON ”position
for approximately 10 seconds before
starting the engine.
CAUTION
If you restart the engine while the
vehicle is moving, shift the selector
lever into the “N ” position. Do not
attempt to place the selector lever of
a moving vehicle into the “P ” posi-
tion. Stopping the engine
The ignition switch should be turned off
only when the vehicle is stopped and the
engine is idling.
WARNING
Do not stop the engine when the
vehicle is moving. This will cause
loss of power to the power steering
and the brake booster, making steer-
ing and braking more difficult. It
could also result in accidental acti-
vation of the “LOCK ”position on the
ignition switch, causing the steering
wheel to lock.

The driver ’s control center differential
allows you to freely change the degree
of limitation of the differential action
(limited slip differential (LSD) torque) of
your vehicle ’s center differential.
By using the center differential control dial,
you can set an initial LSD torque to match
the road surface conditions, driving con-
ditions and your driving style.
1) LSD torque
2) Traction torque
A) Initial LSD torque (adjustable)
B) Mechanical LSD torque &
Auto mode
In the auto mode, the system estimates
the driving and road conditions using
signals from the wheel speed sensor,
throttle position sensor, steering angle
sensor and brake switch, etc. According
to the result, it electronically and auto-
matically controls the degree of limitation
of the differential action (LSD torque) to
optimize the differential action of the
center differential. When the ignition
switch is turned ON, the “AUTO ”indicator
light in the combination meter comes on.
The system can be switched to a manual mode. &
Manual mode
In the manual mode, you can use the
center differential control dial to adjust the
initial LSD torque as desired. When this
mode is selected, the “AUTO ”indicator
light in the combination meter goes off. ! Manual switch
