CAUTION
. Do not allow the retractor to roll
up the seatbelt too quickly.
Otherwise, the metal tongue
plates may hit against the trim,
resulting in damaged trim.
. Have the seatbelt fully rolled up
so that the tongue plates are
neatly stored. A hanging tongue
plate can swing and hit against
the trim during driving, causing
damage to the trim.
& Seatbelt maintenanceTo clean the seatbelts, use a mild soap
and lukewarm water. Never bleach or dye
the belts because this could seriously
affect their strength.
Inspect the seatbelts and attachments
including the webbing and all hardware
periodically for cracks, cuts, gashes,
tears, damage, loose bolts or worn areas.
Replace the seatbelts even if only minor
damage is found.
CAUTION
. Keep the belts free of polishes,
oils, chemicals and particularly
battery acid.
. Never attempt to make modifica-
tions or changes that will prevent
the seatbelt from operating prop-
erly.
Front seatbelt pretensionersThe driver ’s and front passenger ’s seat-
belts have a seatbelt pretensioner. The
seatbelt pretensioners are designed to be
activated in the event of an accident
involving a moderate to severe frontal
collision.
The pretensioner sensor also serves as
the frontal SRS airbag sensor. If the
sensor detects a certain predetermined
amount of force during a frontal collision,
the front seatbelt is quickly drawn back in
by the retractor to take up the slack so that
the belt more effectively restrains the front
seat occupant.
When a seatbelt pretensioner is activated,
an operating noise will be heard and a

Seat, seatbelt and SRS airbags
small amount of smoke will be released.
These occurrences are normal and not
harmful. This smoke does not indicate a
fire in the vehicle.
Once the seatbelt pretensioner has been
activated, the seatbelt retractor remains
locked. Consequently, the seatbelt can not
be pulled out and retracted and therefore
must be replaced.NOTE. Seatbelt pretensioners are not de-
signed to activate in minor frontal
impacts, in side or rear impacts or in
roll-over accidents.
. The driver ’s seat and passenger ’s
seat pretensioners and frontal SRS
airbag operate simultaneously.
. Pretensioners are designed to func-
tion on a one-time-only basis. In the
event that a pretensioner is activated,
both the driver ’s and front passenger ’s
seatbelt retractor assemblies must be
replaced only by an authorized
SUBARU dealer. When replacing seat-
belt retractor assemblies, use only
genuine SUBARU parts.
. If either front seatbelt does not
retract or cannot be pulled out due to
a malfunction or activation of the
pretensioner, contact your SUBARU
dealer as soon as possible. .
If the front seatbelt retractor assem-
bly or surrounding area has been
damaged, contact your SUBARU dealer
as soon as possible.
. When you sell your vehicle, we urge
you to explain to the buyer that it has
seatbelt pretensioners by alerting the
buyer to the contents of this section.
WARNING
. To obtain maximum protection,
the occupants should sit in an
upright position with their seat-
belts properly fastened. Refer to
“ Seatbelts ”F 1-11.
. Do not modify, remove or strike
the front seatbelt retractor as-
semblies or surrounding area.
This could result in accidental
activation of the seatbelt preten-
sioners or could make the sys-
tem inoperative, possibly result-
ing in serious injury. Seatbelt
pretensioners have no user-ser-
viceable parts. For required ser-
vicing of front seatbelt retractors
equipped with seatbelt preten-
sioners, see your nearest
SUBARU dealer.
. When discarding front seatbelt
retractor assemblies or scrap- ping the entire vehicle due to
collision damage or for other
reasons, consult your SUBARU
dealer.
&
System monitorsA diagnostic system continually monitors
the readiness of the seatbelt pretensioner
while the vehicle is being driven. The
seatbelt pretensioners share the control
module with the SRS airbag system.
Therefore, if any malfunction occurs in a
seatbelt pretensioner, the SRS airbag
system warning light will illuminate. For
details, refer to “SRS airbag system
monitors ”F 1-55.& System servicing
WARNING
. When discarding a seatbelt re-
tractor assembly or scrapping
the entire vehicle damaged by a
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

Black plate (51,1)

system inoperative, which may
result in serious injury. Do not
use electrical test equipment on
any circuit related to the seatbelt
pretensioner and SRS airbag
systems. For required servicing
of the seatbelt pretensioner, con-
sult your nearest SUBARU deal-
er.
CAUTION
The front sub sensors are located
on both the right and left sides at the
front of the vehicle, and the SRS
airbag control module including the
impact sensors is located under the
center console. If you need service
or repair in those areas or near the
front seatbelt retractors, have the
work performed by your authorized
SUBARU dealer.NOTEIf the front part of the vehicle is
damaged in an accident to the extent
that the seatbelt pretensioner does not
operate, contact your SUBARU dealer
as soon as possible.
& Precautions against vehicle
modificationAlways consult your SUBARU dealer if
you want to install any accessory parts to
your vehicle.
CAUTION
Do not perform any of the following
modifications. Such modifications
can interfere with proper operation
of the seatbelt pretensioners.
. Attachment of any equipment
(bush bar, winches, snow plow,
skid plate, etc.) other than genu-
ine SUBARU accessory parts to
the front end.
. Modification of the suspension
system or front end structure.
. Installation of a tire of different
size and construction from the
tires specified on the vehicle
placard attached to the driver ’s
door pillar or specified for indivi-
dual vehicle models in this Own-
er ’s Manual.
Child restraint systemsInfants and small children should always
be placed in an infant or child restraint
system in the rear seat while riding in the
vehicle. You should use an infant or child
restraint system that meets Federal Motor
Vehicle Safety Standards or Canada
Motor Vehicle Safety Standards, is com-
patible with your vehicle and is appro-
priate for the child ’s age and size. All child
restraint systems are designed to be
secured in vehicle seats by lap belts or
the lap belt portion of a lap/shoulder belt
(except those described in “Installation of
child restraint systems by use of lower and
tether anchorages (LATCH) ”F 1-29).
Children could be endangered in an
accident if their child restraints are not

Seat, seatbelt and SRS airbags
properly secured in the vehicle. When
installing the child restraint system, care-
fully follow the manufacturer ’s instructions.
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front
seating positions.
All U.S. states and Canadian provinces
require that infants and small children be
restrained in an approved child restraint
system at all times while the vehicle is
moving.
WARNING
Never let a passenger hold a child
on his or her lap or in his or her
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 passenger and objects
inside the vehicle.
Additionally, holding a child in your
lap or arms in the front seat exposes
that child to another serious danger.
Since the SRS airbag deploys with
considerable speed and force, the
child could be injured or even killed.
WARNING
Children should be properly re-
strained at all times. Never allow a
child to stand up, or to kneel on any
seat. Unrestrained children will be
thrown forward during sudden stop
or in an accident and can be injured
seriously.
Additionally, children standing up or
kneeling on or in front of the front
seat are exposed another serious
danger. Since the SRS airbag de-
ploys with considerable speed and
force, the child could be injured or
even killed.

Where to place a child re-
straint systemThe following are SUBARU ’s recommen-
dations on where to place a child restraint
system in your vehicle.

Black plate (53,1)
北米Model "A1110BE-C" EDITED: 2010/ 12/ 17
A: Front passenger ’s seat
You should not install a child restraint
system (including a booster seat) due to
the hazard to children posed by the
passenger ’s airbag.
B: Rear seat, window-side seating
positions
Recommended positions for all types of
child restraint systems.
In these positions, Automatic/Emergency
Locking Retractor (A/ELR) seatbelts and
lower anchorages (bars) are provided for
installing a child restraint system.
Some types of child restraints might not be
able to be secured firmly due to projection
of the seat cushion.
In this seating position, you should use
only a child restraint system that has a
bottom base that fits snugly against the
contours of the seat cushion and can be
securely retained using the seatbelt.
C: Rear seat, center seating position
Installing a child restraint system is not
recommended, although the A/ELR seat-
belt and an upper anchorage (tether
anchorage) (except in Latin American
models) are provided in this position.
Some types of child restraints might not be
able to be secured firmly due to projection
of the seat cushion. In this seating position, you should use
only a child restraint system that has a
bottom base that fits snugly against the
contours of the seat cushion and can be
securely retained using the seatbelt.
If it is unavoidable to install a child
restraint system in the rear seat
’s center
seating position, lower the center head
restraint to the lowest position and install
the child restraint system by correctly
passing the rear center seatbelt through
the belt guide.
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, be sure to secure
ALL types of child restraint devices
(including forward facing child
seats) in the REAR seats at all times.
You should choose a restraint de-
vice which is appropriate for the
child
’s age, height and weight. Ac-
cording to accident statistics, chil-
dren are safer when properly re-
strained in the rear seating posi-
tions than in the front seating posi-
tions.

systemChoose a child restraint system that is
appropriate for the child ’s age and size
(weight and height) in order to provide the
child with proper protection. The child
restraint system should meet all applic-
able requirements of Federal Motor Vehi-
cle Safety Standards for the United States
or of Canada Motor Vehicle Safety Stan-
dards for Canada. It can be identified by looking for the label on the child restraint
system or the manufacturer
’s statement of
compliance in the document attached to
the system.
Also it is important for you to make sure
that the child restraint system is compa-
tible with the vehicle in which it will be
used.
& Installing child restraint sys-
tems with A/ELR seatbelt
WARNING
. Child restraint systems and seat-
belts can become hot in a vehicle
that has been closed up in sunny
weather; they could burn a small
child. Check the child restraint
system before you place a child
in it.
. Do not leave an unsecured child
restraint system in your vehicle.
Unsecured child restraint sys-
tems can be thrown around in-
side of the vehicle in a sudden
stop, turn or accident; they can
strike and injure vehicle occu-
pants as well as result in serious
injuries or death to the child.
CAUTION
When you install a child restraint
system, follow the manufacturer ’s
instructions supplied with it. After
installing the child restraint system,
check to ensure that it is held
securely in position. If it is not held
tight and secure, the danger of your
child suffering personal injury in the
event of an accident may be in-
creased.

CAUTION
When you install a child restraint
system, follow the manufacturer ’s
instructions supplied with it. After
installing the child restraint system,
check to ensure that it is held
securely in position. If it is not held
tight and secure, the danger of your
child suffering personal injury in the
event of an accident may be in-
creased.1. Place the booster seat in the rear
seating position and sit the child on it. The
child should sit well back on the booster
seat. 2. Run the lap and shoulder belt through
or around the booster seat and the child
following the instructions provided by its
manufacturer.
3. Insert the tongue plate into the buckle
until you hear a click. Take care not to
twist the seatbelt.
Make sure the shoulder belt is positioned
across the center of child
’s shoulder and
that the lap belt is positioned as low as
possible on the child ’s hips.
4. To remove the booster seat, press the
release button on the seatbelt buckle and
allow the belt to retract.
WARNING
. Never use a belt that is twisted or
reversed. In an accident, this can increase the risk or severity of
injury to the child.
. Never place the shoulder belt
under the child ’s arm or behind
the child ’s back. If an accident
occurs, this can increase the risk
or severity of injury to the child.
. The seatbelt should fit snugly in
order to provide full restraint.
Loose fitting belts are not as
effective in preventing or redu-
cing injury.
. Place the lap belt as low as
possible on the child ’s hips. A
high-positioned lap belt will in-
crease the risk of sliding under
the lap belt and of the lap belt
sliding up over the abdomen, and
both can result in serious inter-
nal injury or death.
. Make sure the shoulder belt is
positioned across the center of
child ’s shoulder. Placing the
shoulder belt over the neck may
result in neck injury during sud-
den braking or in a collision.
