&Engine exhaust gas (Carbon monoxide)
WARNING
. Never inhale engine exhaust gas.
Engine exhaust gas contains
carbon monoxide, a colorless
and odorless gas which is dan-
gerous, or even lethal, if inhaled.
. Always properly maintain the en-
gine exhaust system to prevent
engine exhaust gas from enter-
ing the vehicle.
. Never run the engine in a closed
space, such as a garage, except
for the brief time needed to drive
the vehicle in or out of it.
. Avoid remaining in a parked
vehicle for a lengthy time while
the engine is running. If that is
unavoidable, then use the venti-
lation fan to force fresh air into
the vehicle.
. Always keep the front ventilator
inlet grille free from snow, leaves
or other obstructions to ensure
that the ventilation system al-
ways works properly.
. If at any time you suspect that
exhaust fumes are entering the vehicle, have the problem
checked and corrected as soon
as possible. If you must drive
under these conditions, drive
only with all windows fully open.
. Keep the trunk lid or rear gate
closed while driving to prevent
exhaust gas from entering thevehicle.
& Drinking and driving
WARNING
Drinking and then driving is very
dangerous. Alcohol in the blood-
stream delays your reaction and
impairs your perception, judgment
and attentiveness. If you drive afterdrinking –even if you drink just a
little –it will increase the risk of
being involved in a serious or fatal
accident, injuring or killing yourself,
your passengers and others. In
addition, if you are injured in the
accident, alcohol may increase the
severity of that injury.
Please don ’t drink and drive.
Drunken driving is one of the most
frequent causes of accidents. Since alco- hol affects all people differently, you may
have consumed too much alcohol to drive
safely even if the level of alcohol in your
blood is below the legal limit. The safest
thing you can do is never drink and drive.
However if you have no choice but to
drive, stop drinking and sober up comple-
tely before getting behind the wheel. &
Drugs and driving
WARNING
There are some drugs (over the
counter and prescription) that can
delay your reaction time and impair
your perception, judgment and at-
tentiveness. If you drive after taking
them, it may increase your, yourpassengers ’and other persons ’risk
of being involved in a serious or
fatal accident.
If you are taking any drugs, check with
your doctor or pharmacist or read the
literature that accompanies the medication
to determine if the drug you are taking can
impair your driving ability. Do not drive
after taking any medications that can
make you drowsy or otherwise affect your
ability to safely operate a motor vehicle. If
you have a medical condition that requires
you to take drugs, please consult with

collision, consult your SUBARU
dealer.
. Tampering with or disconnecting
the system ’s wiring could result
in accidental activation of the
seatbelt pretensioner and/or
SRS airbag or could make the
system inoperative, which may
result in serious injury. The wir-
ing harnesses of the seatbelt
pretensioner and SRS airbag
systems are covered with yellow
insulation and the connectors of
the system are yellow for easy
identification. Do not use electri-
cal test equipment on any circuit
related to the seatbelt preten-
sioner and SRS airbag systems.

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. ! Conditions in which front passen- ger’s SRS frontal airbag is not
activated
The front passenger ’s SRS frontal airbag
will not be activated when any of the
following conditions are met regarding the
front passenger ’s seat:
. The seat is empty.
. The seat is equipped with a rearward
facing child restraint system and an infant
is restrained with it. (See WARNING that follows.) .
The seat is equipped with a forward
facing child restraint system and a small
child is restrained with it. (See WARNING
that follows.) . The seat is equipped with a booster
seat and a small child is in the booster
seat. (See WARNING that follows.) . The seat is relieved of the occupant
load for a time exceeding the predeter-
mined monitoring time period. . The seat is occupied by a child who
has outgrown a child restraint system
(See WARNING that follows.) or by a
small adult. . The front passenger ’s occupant detec-
tion system is faulty.
WARNING
NEVER INSTALL A REARWARD FA-
CING CHILD SEAT IN THE FRONT
PASSENGER ’S SEAT EVEN IF THE
FRONT PASSENGER ’S SRS FRON-
TAL AIRBAG IS DEACTIVATED. Be
sure to install it in the REAR seat in
a correct manner. Also, it is strongly
recommended that any forward fa-
cing child seat or booster seat be
installed in the REAR seat, and that
even children who have outgrown a
child restraint system be also seated in the REAR seat. This is
because children sitting in the frontpassenger
’s seat may be killed or
severely injured should the frontpassenger ’s SRS frontal airbag de-
ploy. REAR seats are the safest
place for children.
When the front passenger ’s seat is occu-
pied by a child, observe the following
precautions. Failure to do so may increase
the load on the front passenger ’s seat,
activating the front passenger ’sSRS
frontal airbag even though that seat is
occupied by a child. . Do not place any article on the seat
other than the child occupant and a child
restraint system. . Do not place more than one child on
the seat.. Do not install any accessory such as a
table or TV onto the seatback.. Do not store a heavy load in the
seatback pocket.. Do not allow the rear seat occupant to
place his/her hands or legs on the front passenger ’s seatback, or allow him/her to
pull the seatback. Seat, seatbelt and SRS airbags

Turntheignitionswitchtothe “OFF ”
position if the front passenger ’s frontal
airbag ON indicator illuminates and the
OFF indicator extinguishes even when an
infant or a small child is in a child restraint
system (including booster seat). Remove
the child restraint system from the seat. By
referring to the child restraint manufac-turer ’s recommendations as well as the
child restraint system installation proce-
dures in the “Child restraint systems ”
section in this chapter, correctly install
the child restraint system. Turn the ignition
switch to the “ON ”position and make sure
that the front passenger ’s frontal airbag
ON indicator goes out and the OFF
indicator comes on.
If still the ON indicator remains illuminated
while the OFF indicator extinguishes, take
the following actions. . Ensure that no article is placed on the
seat other than the child restraint system
and the child occupant. . Ensure that there is no article left in the
seatback pocket. .
Ensure that the backward-forward po-
sition and seatback of front passenger ’s
seat are locked into place securely by
moving the seat back and forth.
If the ON indicator still illuminates while
the OFF indicator extinguishes after taking
relevant corrective actions described
above, relocate the child restraint system
to the rear seat and immediately contact
your SUBARU dealer for an inspection.
NOTE
When a child who has outgrown a child
restraint system or a small adult is
seated in the front passenger ’s seat,
the Subaru advanced frontal airbag
system may or may not activate the
front passenger ’s SRS frontal airbag
depending on the occupant ’s seating
posture. If the front passenger ’s SRS
frontal airbag is activated (the ON
indicator illuminates while the OFF
indicator extinguishes), take the follow-
ing actions. . Ensure that no article is placed on
the seat other than the occupant. . Ensure that there is no article left in
the seatback pocket.
If the ON indicator still illuminates while
the OFF indicator extinguishes despite
the fact that the actions noted above have been taken, seat the child/small
adult in the rear seat and immediately
contact your SUBARU dealer for an
inspection. Even if the system has
passed the dealer inspection, it is
recommended that on subsequent trips
the child/small adult always take the
rear seat.
Children who have outgrown a child
restraint system should always wear the
seatbelt irrespective of whether the airbag
is deactivated or activated. !
Conditions in which front passen- ger’s SRS frontal airbag is activated
The front passenger ’s SRS frontal airbag
will be activated for deployment upon
impact when any of the following condi-
tions are met regarding the front passen- ger ’s seat.
. When the seat is occupied by an adult.
. When a heavy article is placed on the
seat.
When the front passenger ’s seat is occu-
pied by an adult, observe the following
precautions. Failure to do so may lessen
the load on the front passenger ’s seat,
deactivating the front passenger ’s SRS
frontal airbag despite the fact that the seat
is occupied by an adult. . Do not allow the rear seat occupant to

The SRS airbag can function only when
the ignition switch is in the“ON ”position.
The Subaru advanced frontal airbag sys-
tem is designed to determine the activa-
tion or deactivation condition of the frontpassenger ’s SRS frontal airbag depend-
ing on the total load on the front passen-ger ’s seat monitored by the front passen-
ger ’s occupant detection system weight
sensor. For this reason, only the driver ’s
SRS frontal airbag may deploy in the
event of a collision, but this does not mean
failure of the system.
If the front sub sensors inside both front
fenders and the impact sensors in the
airbag control module detect a predeter-
mined amount of force during a frontal
collision, the control module sends signals
to the airbag module(s) (only driver ’s
module or both driver ’s and front passen-
ger ’s modules) instructing the module(s)
to inflate the SRS frontal airbag(s). Thedriver ’s and front passenger ’s SRS frontal
airbags use dual stage inflators.
The two inflators of each airbag are
triggered either sequentially or simulta-
neously, depending on the severity of
impact, backward-forward adjustment of
the driver ’s seat position and fastening/
unfastening of the seatbelt in the case of
the driver ’s SRS frontal airbag and de-
pending on the severity of impact and the total load on the seat in the case of the
front passenger
’s SRS frontal airbag. After
deployment, the SRS airbag immediately
starts to deflate so that the driver ’s vision
is not obstructed. The time required from
detecting impact to the deflation of the
SRS airbag after deployment is shorter
than the blink of an eye.
Both when only the driver ’s SRS frontal
airbag deploys and the driver ’s and front
passenger ’s SRS frontal airbags deploy,
the driver ’s and front passenger ’s seatbelt
pretensioners operate at the same time.
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 vision
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 a normal result of the
deployment. This smoke does not indicate
a fire in the vehicle.
CAUTION
Do not touch the SRS airbag system
components around the steering
wheel and dashboard with bare hands right after deployment. Doing
so can cause burns because the
components can be very hot as a
result of deployment.
The driver ’s SRS frontal airbag and front
passenger ’s SRS frontal airbag are de-
signed 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 be-
cause the necessary protection can be
achieved by the seatbelt alone. Also, they
are basically not designed to deploy in
side or rear impacts or in roll-over acci-
dents because deployment of only thedriver ’s SRS frontal airbag or both driver ’s
and front passenger ’s SRS frontal airbags
would not help the occupant in those
situations. The driver ’s and front passen-
ger ’s SRS frontal airbags are designed to
function on a one-time-only basis.
SRS airbag deployment depends on the
level of force experienced in the passen-
ger compartment during a collision. That
level differs from one type of collision to
another, and it may have no bearing on
the visible damage done to the vehicleitself. Seat, seatbelt and SRS airbags

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

Immobilizer (Turbo models)
The immobilizer system is designed to
prevent an unauthorized person from
starting the engine. Only keys registered
with your vehicle’s immobilizer system can
be used to operate your vehicle. Even if
an unregistered 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 trans-
ponder 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 thekey ’s ID code to the immobilizer system ’s
receiver. If the transmitted ID code
matches the ID code registered in the
immobilizer system, 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 normal starting of the engine.
If the engine fails to start, pull out the key
once before trying again. (Refer to the“ Ignition switch ”section in chapter 3.)
