Seat, seatbelt and SRS airbags/Front seatbelt pretensioners
&Seatbelt maintenance
To 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 pretensioners
The 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
and side collision and rollover accident.
& Seatbelt with shoulder belt
pretensioner
NOTE
This section is applicable to the follow-
ing components.
. Except Crosstrek models:
– Driver ’s seatbelt
– Front passenger ’s seatbelt
. Crosstrek models:
– Driver ’s seatbeltThe pretensioner sensor also serves as
follows.
. SRS frontal airbag sensor
. Side impact sensor
. Front door impact sensor
. Rollover sensor (Crosstrek models)
If the sensor detects a certain predeter-
mined amount of force during frontal or
side collisions or rollover accidents, the
front seatbelt is quickly drawn back in by
the retractor to take up the slack so that
the belt more effectively restrains the
driver.
When a seatbelt pretensioner is activated,
an operating noise will be heard and a
small amount of smoke will be released.
These occurrences are normal and not
harmful. This smoke does not indicate a
1-20

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 impacts or
in rear impacts.
. In the case of rollover accidents
– Crosstrek models:
As the curtain airbags deploy, the
driver ’s side seatbelt pretensioner
and front passenger ’sside
shoulder belt pretensioner are acti-
vated simultaneously.
– Except Crosstrek models:
Seatbelt pretensioners are not acti-
vated.
. In cases of frontal collisions, the
following components will operate si-
multaneously.
–Seatbelt pretensioner for driver
– Seatbelt pretensioner for front
passenger
– SRS frontal airbag for driver
– SRS frontal airbag for front pas-
senger*
– SRS curtain airbags (both sides) (if an offset frontal collision occurs)
*: This does not operate if the occupant
detection system deactivates airbag op-
eration. For details, refer to
“Front
passenger ’s SRS frontal airbag ”F 1-48
.
. In cases of side collisions, the
following components will operate si-
multaneously.
–SRS curtain airbag (impacted
side)
– SRS side airbag (impacted side)
(when both the satellite safing sen-
sor and any of the center pillar
impact sensors/front door impact
sensors sense an impact force)
– Seatbelt pretensioner for driver
(when both the satellite safing sen-
sor and the driver ’s side front door
impact sensor sense an impact
force)
However, when a center pillar im-
pact sensor detects a signal faster
than the front door impact sensor,
or both sensors detect signals
simultaneously, the seatbelt preten-
sioner does not activate.
– Seatbelt pretensioner for front
passenger (shoulder belt preten-
sioner only) (when both the satellite
safing sensor and the front passen-
ger ’s side front door impact sensor
sense an impact force) However, when a center pillar im-
pact sensor detects a signal faster
than the front door impact sensor,
or both sensors detect signals
simultaneously, the seatbelt preten-
sioner does not activate.
. 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 should
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.

& Seatbelt with shoulder belt
and lap belt pretensioners
NOTE
This section is applicable to the front
passenger ’s seatbelt in Crosstrek mod-
els.
1) Seatbelt retractor assembly (shoulder belt pretensioner)
2) Lap belt pretensioner
On the front passenger ’s side in Crosstrek
models, the shoulder belt pretensioner is
supplemented by a lap belt pretensioner,
which is located at the base of the center
pillar. Like the shoulder belt pretensioner,
the lap belt pretensioner instantaneously
pulls in the belt to eliminate slack if a
certain level of frontal collision force is
detected. As a result, the seatbelt re- strains the front seat occupant more
effectively.
When a seatbelt pretensioner is activated,
an operating noise will be heard and a
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 pretensioner re-
mains locked. Consequently, the seatbelt
cannot be pulled out and retracted and
therefore must be replaced.
NOTE
.
Seatbelt pretensioners are not de-
signed to activate in minor impacts or
in rear impacts.
. When a rollover accident occurs, the
lap belt pretensioner does not activate;
however, as the curtain airbags deploy,
the shoulder belt pretensioner is acti-
vated. At this time, the driver ’s side
seatbelt pretensioner and passenger ’s
side shoulder belt pretensioner acti-
vate simultaneously.

& 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
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 sensors and SRS airbag control
modules are located in the following
locations.
.
Front sub sensors: on both the
right and left side at the front of
the vehicle
. Front door impact sensors: on
both front doors
. Satellite safing sensor: under the
rear center seat
. SRS airbag control module (in-
cluding the impact sensors): un-
der the center of the instrument
panel
If you need service or repair in those
areas or near the front seatbelt
retractors, have the work performed
by your authorized SUBARU dealer.
NOTE
If the front or side 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.

Child restraint systems
Infants 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 1-33).
Children could be endangered in an
accident if their child restraints are not 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

Seat, seatbelt and SRS airbags/Child restraint systems
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 system
The following are SUBARU ’s recommen-
dations on where to place a child restraint
system in your vehicle.
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, the following equip-
ment is provided for installing a child
restraint system.
. Automatic Locking Retractor/Emer-
gency Locking Retractor (ALR/ELR) seat-
belts
. Lower anchorages (bars)
. Upper anchorages (tether anchorages)
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
The ALR/ELR seatbelt and an upper
anchorage (tether anchorage) are pro-
vided 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.
When you install a child restraint system in
the rear seat
’s center seating position,
raise the center head restraint.
Lower anchorages (bars) for window-side
seating positions may be used for a seat
in the center seating position if a child
restraint system manufacturer ’s instruc-
tions permit and specify using anchors as
far apart as those in this vehicle.
If a child restraint system is not correctly
fixed in place (for example, if a child
restraint system can be moved more than
1 inch (2.5 cm) from side to side), you
should install the child restraint system in
a rear seat, window-side seating position.
WARNING
. Even with advanced airbags, chil-
dren can be seriously injured by
the airbag. Place children in the
rear seat properly restrained at
all times. The SRS airbag de-
ploys with considerable speed
1-26

and force and can injure or even
kill children, especially if they are
not restrained or improperly re-
strained. Because children are
lighter and weaker than adults,
their risk of being injured from
deployment is greater.
For that reason, be sure to se-
cure ALL types of child restraint
devices (including forward facing
child seats) in the REAR seats at
all times. You should choose a
restraint device which is appro-
priate for the child’s age, height
and weight. According to acci-
dent statistics, children are safer
when properly restrained in the
rear seating positions than in the
front seating positions.
. Do not use lower anchorages
(bars) for a seat in the center
seating position unless a child
restraint system manufacturer ’s
instructions permit and specify
using anchors spaced as far
apart as those in this vehicle.
WARNING
SINCE YOUR VEHICLE IS
EQUIPPED WITH A PASSENGER ’S
SRS AIRBAG, NEVER INSTALL A
REARWARD FACING CHILD
SAFETY SEAT IN THE FRONT PAS-
SENGER ’S SEAT. DOING SO RISKS
SERIOUS INJURY OR DEATH TO
THE CHILD BY PLACING THE
CHILD’ SHEADTOOCLOSETO
THE SRS AIRBAG.
& Choosing a child restraint
system
Choose 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 ALR/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 manufac-
turer ’s instructions supplied with
it. After installing the child re-
straint system, check to ensure
that it is held securely in posi-
tion. If it is not held tight and secure, the danger of your child
suffering personal injury in the
event of an accident may be
increased.
. When installing a child restraint
system in the rear center seating
position, set both seatbacks to
the original position. Otherwise,
the child restraint system cannot
be securely restrained, which
may result in death or serious
injuries in the event of sudden
stop, sudden steering maneuver
or an accident.
! Installing a rearward facing child
restraint
1. Place the child restraint system in the rear seating position.
2. Run the lap and shoulder belt through
or around the child restraint system
following the instructions provided by its
manufacturer.
3. Insert the tongue plate into the buckle
until you hear a click.
4. Take up the slack in the lap belt.
5. Pull out the seatbelt fully from the
retractor to change the retractor over from
the Emergency Locking Retractor (ELR)
to the Automatic Locking Retractor (ALR)
function. Then, allow the belt to rewind
into the retractor. As the belt is rewinding,
clicks will be heard which indicate the
retractor functions as ALR.

6. Push and pull the child restraint
system forward and from side to side to
check if it is firmly secured. Sometimes a
child restraint can be more firmly secured
by pushing it down into the seat cushion
and then tightening the seatbelt.
7. Pull at the shoulder portion of the belt
to confirm that it cannot be pulled out (ALR
properly functioning).8. To remove the child restraint system,
press the release button on the seatbelt

WARNING
Before installing a child restraint
system, be sure to confirm that the
seatback is securely locked into
place. Otherwise, in an accident,
serious injury or death could result.
1. Shake the seatback slightly to confirm
that it is securely locked into place. –It is possible to check whether the
seatback is locked visually. If the
