Carefully read the sect ions “Child restraint
systems”,“*SRS airbag (Supplemental
Restraint System airbag)”, and “Seatbelts”
in chapter 1 of this owner’s manual for in-
structions and precau tions concerning the
child restraint system, seatbelt system
and SRS airbag system. „ Engine exhaust gas (carbon
monoxide)„Drinking and driving
Drunken driving is one of the most fre-
quent causes of accidents. Since alcohol
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 com-
pletely before getting behind the wheel.
yNever inhale engine exhaust gas.
Engine exhaust gas contains car-
bon monoxide, a colorless and
odorless gas which is dangerous,
or even lethal, if inhaled.
yAlways properly maintain the en-
gine exhaust system to prevent
engine exhaust gas from entering
the vehicle.
yNever 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.
yAvoid remaining in a parked vehi-
cle for a lengthy ti me while the en-
gine is running. If that is unavoid-
able, then use th e ventilation fan
to force fresh air into the vehicle.
yAlways keep the front ventilator
inlet grille free from snow, leaves
or other obstructions to ensure
that the ventilation system always
works properly.
yIf at any time you suspect that ex-
haust fumes are entering the vehi-
cle, have the problem checked
and corrected as soon as possi-
ble. If you must drive under these
conditions, drive only with all win-
dows fully open.
yKeep the trunk lid or rear gate
closed while driving to prevent ex-
haust gas from entering the vehi-
cle.
Drinking and then driving is very
dangerous. Alcohol in the blood-
stream delays your reaction and im-
pairs your perception, judgment and
attentiveness. If you drive after
drinking – even if you drink just a lit-
tle – it will increase the risk of being
involved in a serious or fatal acci-
dent, injuring or killing yourself,
your passengers and others. In ad-
dition, if you are injured in the acci-
dent, alcohol may increase the se-
verity of that injury.
Please don’t drink and drive.

Drugs and driving
If you are taking any drugs, check with
your doctor or pharmacist or read the liter-
ature that accompanies the medication to
determine if the drug you are taking can
impair your driving ability. Do not drive af-
ter 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, plea se consult with your
doctor.
Never drive if you are under the influence
of any illicit mind-altering drugs. For your
own health and well-being, we urge you
not to take illegal drugs in the first place
and to seek treatment if you are addicted
to those drugs. „
Driving when tired or sleepyPlease do not continue to drive but in-
stead find a safe place to rest if you are
tired or sleepy. On long trips, you should
make periodic rest stops to refresh your-
self before continuing on your journey.
When possible, you should share the driv-
ing with others. „
Car phone/cell phone and driving
„Modification of your vehicle
„Driving with pets
Unrestrained pets can interfere with your
driving and distract your attention from
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, your
passengers’ and other persons’ risk
of being involved in a serious or fa-
tal accident.When you are tired or sleepy, your
reaction will be delayed and your
perception, judgment and attentive-
ness will be impaired. If you drive
when tired or sleepy, your, your pas-
sengers’ and other persons’ chanc-
es of being involved in a serious ac-
cident may increase.
Do not use a car phone/cell phone
while driving; it may distract your at-
tention from driving and can lead to
an accident. If you use a car phone/
cell phone, pull off the road and park
in the a place before using your
phone. In some States/Provinces,
only hands-free phones may legally
be used while driving.
Your vehicle should not be modi-
fied. Modification could affect its
performance, safet y or durability,
and may even violate governmental
regulations. In addition, damage or
performance problems resulting
from modification may not be cov-
ered under warranties.

T
Conditions in which front passen-
ger’s SRS frontal airbag is not acti-
vated
The front passenger’s SRS frontal airbag
will not be activated when any of the fol-
lowing conditions are met regarding the
front passenger’s seat:y The seat is empty.
y The seat is equipped with a rearward
facing child restrain t system and an infant
is restrained with it. (See WARNING that follows.) y The seat is equipped with a forward fac-
ing child restraint syst em and a small child
is restrained with it. (See WARNING thatfollows.)y The seat is equipped with a booster
seat and a small child is in the booster
seat. (See WARNING that follows.) y The seat is relieved of the occupant
load for a time exceeding the predeter-
mined monitoring time period. y The seat is occupied by a child who has
outgrown a child restraint system (See
WARNING that follows .) or by a small
adult. y The front passenger’s occupant detec-
tion system is faulty.
When the front passenger’s seat is occu-
pied by a child, observe the following pre-
cautions. Failure to do so may increase
the load on the front passenger’s seat, ac-
tivating the front passenger’s SRS frontal
airbag even though that seat is occupied
by a child. y Do not place any article on the seat oth-
er than the child occupant and a child re- straint system. y
Do not place more than one child on the
seat. y Do not install any accessory such as a
table or TV onto the seatback. y Do not store a heavy load in the seat-
back pocket. y 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. V If the front passen ger’s frontal air-
bag 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)
Turn the ignition switch to the “OFF” posi-
tion if the front passenger’s frontal airbag
ON indicator illuminates and the OFF indi-
cator 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 refer-
ring to the child restraint manufacturer’s
recommendations as well as the child re-
straint system installation procedures in
the “Child restraint systems” section in this chapter, correctly inst all the child restraint
system. Turn the igniti on switch to the
“ON” position and make sure that the front
passenger’s frontal airbag ON indicator
NEVER INSTALL A REARWARD
FACING 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 fac-
ing child seat or booster seat be in-
stalled in the REAR seat, and that
even children who have outgrown a
child restraint system be also seat-
ed in the REAR seat. This is because
children sitting in the front passen-
ger’s seat may be killed or severely
injured should the front passenger’s
SRS frontal airbag deploy. REAR
seats are the safest place for chil-
dren.

1-48 Seat, seatbelt and SRS airbags
goes out and the OFF indicator comes on.
If still the ON indicator remains illuminated
while the OFF indicator extinguishes, take
the following actions. yEnsure that no article is placed on the
seat other than the child restraint system
and the child occupant. y Ensure that there is no article left in the
seatback pocket. y Ensure that the backward-forward posi-
tion and seatback of front passenger’s
seat are locked into place securely by
moving the seat back and forth. (Models
equipped with manual seats only)
If the ON indicator still illuminates while
the OFF indicator extinguishes after tak-
ing 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 indi- cator illuminates while the OFF indica- tor extinguish
es), take the following
actions. y Ensure that no article is placed on
the seat other than the occupant.y 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 immedi-
ately contact your SUBARU dealer for
an inspection. Even if the system has
passed the dealer inspection, it is rec-
ommended that on subsequent trips
the child/small adult always take the
rear seat.
Children who have outgrown a child re-
straint system should always wear the
seatbelt irrespective of whether the airbag
is deactivated or activated. T 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 im-
pact when any of the following conditions
is met regarding the front passenger’s seat.y When the seat is occupied by an adult. y
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, de-
activating the front passenger’s SRS fron-
tal airbag despite the fact that the seat is
occupied by an adult.y Do not allow the r ear seat occupant to
lift the front passenger’s seat cushion us-
ing his/her feet.y Do not place any article under the front
passenger’s seat, or squeeze any article
from behind and under the seat. This may
lift the seat cushion.y Do not squeeze any article between the
front passenger’s seat and side trim/pillar,
door or center consol e box. This may lift
the seat cushion. V If the passenger’s frontal airbag
OFF indicator illuminates and the
ON indicator extinguishes even
when the front passenger’s seat is
occupied by an adult
This can be caused by the adult incorrect-
ly sitting in the front passenger’s seat.
Turn the ignition switch to the “OFF” posi-
tion. Ask the front passenger to set the
seatback to the upri ght position, sit up
straight in the center of the seat cushion,

1-50 Seat, seatbelt and SRS airbags
TOperation
1) Driver’s side
2) Passenger’s side
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 front
passenger’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 air-
bag control module detect a predeter-
mined amount of force during a frontal col-
lision, the control module sends signals to
the airbag module(s) (only driver’s module
or both driver’s and front passenger’s
modules) instructing the module(s) to in-
flate the SRS frontal airbag(s). The driv-
er’s and front passenger’s SRS frontal air-
bags use dual stage inflators. The two in-
flators of each airbag are triggered either
sequentially or simultaneously, depending
on the severity of impact, backward-for-
ward adjustment of the driver’s seat posi-
tion and fastening/unfas tening of the seat-
belt in the case of the driver’s SRS frontal
airbag and depending 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 de-
flation 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 abil-
ity 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 oc-
currences are a normal result of the de-
ployment. This smoke does not indicate a
fire in the vehicle.

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.
