Safety precautions when driving &Seatbelt and SRS airbag
WARNING
. All persons in the vehicle should
fasten their seatbelts BEFORE
the vehicle starts to move. Other-
wise, the possibility of serious
injury becomes greater in the
event of a sudden stop or acci-dent.
. To obtain maximum protection in
the event of an accident, the
driver and all passengers in the
vehicle should always wear seat-
belts when the vehicle is moving.
The SRS (Supplemental Restraint
System) airbag does not do away
with the need to fasten seatbelts.
In combination with the seat-
belts, it offers the best combined
protection in case of a seriousaccident.
Not wearing a seatbelt increases
the chance of severe injury or
death in a crash even when the
vehicle has the SRS airbag. .
The SRS airbags deploy with
considerable speed and force.
Occupants who are out of proper
position when the SRS airbag
deploys could suffer very serious
injuries. Because the SRS airbag
needs enough space for deploy-
ment, the driver should always
sit upright and well back in the
seat as far from the steering
wheel as practical while still
maintaining full vehicle control
and the front passenger should
move the seat as far back as
possible and sit upright and well
back in the seat.
For instructions and precautions, carefully
read the following sections. . For the seatbelt system, refer to “Seat-
belts ”F 1-11.
. For the SRS airbag system, refer to
“ *SRS airbag (Supplemental Restraint
System airbag) ”F 1-35. &
Child safety
WARNING
. Never hold a child on your lap or
in your arms while the vehicle is
moving. The passenger cannot
protect the child from injury in a
collision, because the child will
be caught between the passen-
ger and objects inside the vehi-cle.
. While riding in the vehicle, in-
fants and small children should
always be placed in the REAR
seat in an infant or child restraint
system which is appropriate for
the child ’s age, height and
weight. If a child is too big for a
child restraint system, the child
should sit in the REAR seat and
be restrained using the seatbelts.
According to accident statistics,
children are safer when properly
restrained in the rear seating
positions than in the front seat-
ing positions. Never allow a child
to stand up or kneel on the seat.
. Put children aged 12 and under in
the REAR seat properly re-
strained at all times in a child
restraint device or in a seatbelt. 5

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 time
and impairs your perception, judg-
ment and attentiveness. If you drive
after drinking –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 drivingWARNING
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
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. 7

&Tire pressures
Check and, if necessary, adjust the
pressure of each tire (including the spare)
at least once a month and before any long
journey.
Check the tire pressure when the tires are
cold. Use a pressure gauge to adjust the
tire pressures to the values shown on the
tire placard. For detailed information, referto “Tires and wheels ”F 11-31.
WARNING
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to deform severely and to
rapidly become hot. A sharp in-
crease in temperature could cause
tread separation, and destruction of
the tires. The resulting loss of
vehicle control could lead to anaccident. &
California proposition 65 warning
WARNING
Engine exhaust, some of its consti-
tuents, and certain vehicle compo-
nents contain or emit chemicals
known to the State of California to
cause cancer and birth defects or
other reproductive harm. In addi-
tion, certain fluids in vehicles and
certain components of product wear
contain or emit chemicals known to
the State of California to cause
cancer and birth defects or other
reproductive harm.
& California Perchlorate Advi- sory
Certain vehicle components such as air-
bag modules, seatbelt pretensioners and
keyless entry transmitter batteries may

handling may apply for service or vehicle
end of life disposal. See www.dtsc.ca.gov/hazardouswaste/perchlorate. 9

1-2Seat, seatbelt and SRS airbags
Front seats
WARNING
. Never adjust the seat while driv-
ing to avoid the possibility of
loss of vehicle control and of
personal injury.
. Before adjusting the seat, make
sure the hands and feet of rear
seat passengers and cargo are
clear of the adjusting mechan-ism.
. After adjusting the seat, push it
slightly to make sure it is se-
curely locked. If the seat is not
securely locked, it may move or
the seatbelt may not operate
properly.
. Do not put objects under the front
seats. They may interfere with
front seat locking and cause anaccident.
. Seatbelts provide maximum re-
straint when the occupant sits
well back and upright in the seat.
To reduce the risk of sliding
under the seatbelt in a collision,
the front seatbacks should be
always used in the upright posi-
tion while the vehicle is running. If the front seatbacks are not
used in the upright position in a
collision, the risk of sliding under
the lap belt and of the lap belt
sliding up over the abdomen will
increase, and both can result in
serious internal injury or death.
. The SRS airbags deploy with
considerable speed and force.
Occupants who are out of proper
position when the SRS airbag
deploys could suffer very serious
injuries. Because the SRS airbag
needs enough space for deploy-
ment, the driver should always
sit upright and well back in the
seat as far from the steering
wheel as practical while still
maintaining full vehicle control
and the front passenger should
move the seat as far back as
possible and sit upright and well
back in the seat.
WARNING
Put children aged 12 and under in
the rear seat properly restrained at
all times. The SRS airbag deploys
with considerable speed and force
and can injure or even kill children,
especially if they are 12 years of age
and under and are not restrained or
improperly restrained. Because chil-
dren are lighter and weaker than
adults, their risk of being injured
from deployment is greater. For that
reason, we strongly recommend
that ALL children (including those
in child seats and those that have
outgrown child restraint devices) sit
in the REAR seat properly re-
strained at all times in a child

.Seatbelts provide maximum re-
straint when the occupant sits
well back and upright in the seat.
To reduce the risk of sliding
under the seatbelt in a collision,
the front seatbacks should be
always used in the upright posi-
tion while the vehicle is running.
If the front seatbacks are not
used in the upright position in a
collision, the risk of sliding under
the lap belt and of the lap belt
sliding up over the abdomen will
increase, and both can result in
serious internal injury or death.
. Do not put cushions or any other
materials between occupants
and seatbacks or seat cushions.
If you do so, the risk of sliding
under the lap belt and of the lap
belt sliding up over the abdomen
will increase, and both can result
in serious internal injury ordeath.
WARNING
Never place the shoulder belt under
the arm or behind the back. If an
accident occurs, this can increase
the risk or severity of injury.
CAUTION
Metallic parts of the seatbelt can
become very hot in a vehicle that
has been closed up in sunny weath-
er; they could burn an occupant. Do
not touch such hot parts until theycool. !
Front seatbelts
1. Adjust the seat position according to
the following procedure. Driver ’s seat: Adjust the seatback to the
upright position. Move the seat as far from
the steering wheel as practical while still
maintaining full vehicle control.
Front passenger ’s seat: Adjust the seat-
back to the upright position. Move the seat
as far back as possible.
2. Sit well back in the seat.
3. Pick up the tongue plate and pull the
belt out slowly. Do not let it get twisted. If
the belt stops before reaching the buckle,
return the belt slightly and pull it out more
slowly. If the belt still cannot be unlocked,
let the belt retract slightly after giving it a
strong pull, then pull it out slowly again.

back in the seat.
. Do not place any objects over or
near the SRS airbag cover or
between you and the SRS airbag.
If the SRS airbag deploys, those
objects could interfere with its
proper operation and could be
propelled inside the vehicle and
cause injury.WARNING
. Put children aged 12 and under in
the rear seat properly restrained

REAR seat properly restrained at
all times in a child restraint
device or in a seatbelt, whichever
is appropriate for the child ’s age,
height and weight.
Secure ALL types of child re-
straint devices (including for-
ward facing child seats) in the
REAR seats at all times.
According to accident statistics,
children are safer when properly
restrained in the rear seating positions than in the front seat-
ing positions.
For instructions and precautions
concerning the child restraint
system, refer to
“Child restraint
systems ”F 1-21.
. NEVER INSTALL A REARWARD
FACING CHILD SEAT IN THE
FRONT SEAT. DOING SO RISKS
SERIOUS INJURY OR DEATH TO
THE CHILD BY PLACING THECHILD ’S HEAD TOO CLOSE TO
THE SRS AIRBAG.
. Never allow a child to stand up,
or to kneel on the front passen-ger ’s seat, or never hold a child
on your lap or in your arms. The
SRS airbag deploys with consid-
erable force and can injure or
even kill the child.
CAUTION
. When the SRS airbag deploys,
some smoke will be released.
This smoke could cause breath-
ing problems for people with a
history of asthma or other
breathing trouble. If you or your
passengers have breathing pro-
blems after SRS airbag deploys,

&SUBARU advanced frontal
airbag system
Your vehicle is equipped with a SUBARU
advanced frontal airbag system that com-
plies with the new advanced frontal airbag
requirements in the amended Federal
Motor Vehicle Safety Standard (FMVSS)
No. 208.
The SUBARU advanced frontal airbag
system automatically determines the de-
ployment force of the driver ’s SRS frontal
airbag at the time of deployment as well as
whether or not to activate the frontpassenger ’s SRS frontal airbag and, if
activated, the deployment force of the
SRS frontal airbag at the time of deploy-ment.
Your vehicle has warning labels on the driver ’s and front passenger ’s sun visors
beginning with the phrase “EVEN WITH
ADVANCED AIR BAGS ”and a tag
attached to the glove box lid beginning
with the phrase “Even with Advanced Air
Bags ”. Make sure that you carefully read
the instructions on the warning labels and tag.
Always wear your seatbelt. The SUBARU
advanced frontal airbag system is a
supplemental restraint system and must
be used in combination with a seatbelt. All
occupants should wear a seatbelt or be
seated in an appropriate child restraint system.
The driver
’s SRS frontal airbag is stowed
in the center portion of the steering wheel.
The front passenger ’s SRS frontal airbag
is stowed near the top of the dashboard
under an “SRS AIRBAG ”mark.
In a moderate to severe frontal collision,
the driver ’s and front passenger ’s SRS
frontal airbags deploy and supplement the
seatbelts by reducing the impact on thedriver ’s and front passenger ’s head and
chest.
WARNING
NEVER INSTALL A REARWARD FA-
CING CHILD SEAT IN THE FRONT
SEAT. DOING SO RISKS SERIOUS
INJURY OR DEATH TO THE CHILD BY PLACING THE CHILD
’S HEAD
TOO CLOSE TO THE SRS AIRBAG.
WARNING
Never allow a child to stand up, or to
kneel on the front passenger ’s seat.

The SRS airbag deploys with con-
siderable speed and force. Occu-
pants who are out of proper position
when the SRS airbag deploys could
suffer very serious injuries. Be-
cause the SRS airbag needs enough

It is also important to wear your seatbelt to help avoid injuries that
can result when the SRS airbag
contacts an occupant not in proper
position such as one thrown toward
the front of the vehicle during pre-
accident braking.
WARNING
Do not put any objects over the
steering wheel pad and dashboard.
If the SRS frontal airbag deploys,
those objects could interfere with its
proper operation and could be pro-
pelled inside the vehicle and cause
injury.
