When you sell your vehicle, we urge
you to inform the bu yer that the vehicle
is equipped with seatbelt
pretensioners. Also, notify the buyer of
the contents in this section.■ Front seatbelt with Shoulder
Belt PretensionerThe pretensioner sensor also serves as
follows.
 Front impact sensor
 Side impact sensor
 Rollover sensor
If the sensor detects a certain predeter-
mined amount of force during frontal or
side collisions or rollover accidents, any
seatbelt that has a se atbelt pretensioner is
quickly drawn back in by the retractor to take up the slack so
that the belt more
effectively restrains the seat occupant.
The front seatbelt pretensioner includes a
tension reducing device which limits the
peak forces exerted by the seatbelt on the
occupant in the event of a collision. The
front passenger's side adaptive force
limiter will select a reducing load to suit the
body size of the occupant as detected by
the occupant detection sensor.
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 retractor remains
locked. Consequently, the seatbelt cannot
be pulled out and retracted and therefore
must be replaced.
■ System MonitorsA diagnostic system continually monitors
the readiness of the seatbelt pretensioner
with the ignition switch in the “ON” posi-
tion. The seatbelt pr etensioners 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" P87.
■ System Servicing
100121
WARNING
When discarding a seatbelt
retractor 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 elec-
trical test equipment on any
circuit related to the seatbelt
pretensioner and SRS airbag
systems. For required servicing
of the seatbelt pretensioner,
consult your nearest SUBARU
dealer.
CAUTION
For the locations of the sensors and
control modules, refer to "Compo-
nents" P68.

46NOTEIf 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.■ Precautions against Vehicle
ModificationAlways consult your SUBARU dealer if
you want to install any accessory parts to
your vehicle.
1-6. Child Restraint Systems■ Safety precautionsInfants 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 compatible
with your vehicle and is appropriate 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)" P55).
If you need service or repair in
those areas or near the front
seatbelt retractors, have the work
performed by your authorized
SUBARU dealer.
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
genuine 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
center pillar or specified for indi-
vidual vehicle models in this
Owner’s Manual.

Children could be endangered in an acci-
dent if their child restraint systems are not
properly secured in the vehicle. When
installing the child re straint system, care-
fully follow the manufacturer’s instruc-
tions.
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.Lock release button

WARNING
Before installing a child restraint
system, be sure to confirm that
the seatback is securely locked
into place. Otherwise, in an acci-
dent, serious injury or death
could result. Do not leave children in the car
unattended. High interior
temperatures may cause heat
stroke and dehydration that
result in serious injury or death.
100125
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 (or infant) from injury in a col-
lision, because the child will be
caught between the passenger and
objects inside the vehicle. Addition-
ally, 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.

48■Safety Tips for Installing
Child Restraint Systems
■Where to Place a Child
Restraint SystemThe following descriptions are SUBARU’s
recommendations on where to place a
child restraint system in your vehicle.
WARNING
Children should be properly
restrained 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 seri-
ous danger. Since the SRS airbag
deploys with considerable speed
and force, the child could be injured
or even killed.
WARNING
 Child restraint systems and
seatbelts 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 use a seatbelt extender. If
a seatbelt extender is used when
installing a child restraint system,
the seatbelt will not securely hold
the child restraint system. Use of
a seatbelt extender could cause
death or serious injury to children
or other passengers in sudden
braking, swerving, or accidents. Attach the child restraint system
to the anchors properly. When
using the LATCH anchors, be
sure that there are no foreign
objects around the anchors.
Make sure the child restraint
system is securely attached.
Otherwise it may cause death or
serious injury to children or other
passengers in sudden braking,
swerving, or accidents. Do not leave an unsecured child
restraint system in your vehicle.
Unsecured child restraint
systems can be thrown around
inside 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
increased.
WARNING
 Several types of child restraint
systems may conceal the buckle
of the neighboring seat. If the
occupant of the neighboring seat
cannot correctly fasten the
seatbelt, that person must move
to a different seat. If the seatbelt
cannot be correctly fastened,
there is the risk of serious injury
or death in the event of sudden
braking or a collision.

– CONTINUED –
A: Front passenger’s seat
You should not install a child restraint
system (including a bo oster seat) due to
the hazard to children posed by the
passenger’s airbag.
B: Rear seat
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)
seatbelts
 Lower anchorages (bars)
 Upper anchorages (tether anchorages)
Some types of child restraint systems
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 restrain t 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 the child restraint system
cannot be correctly installed
because it contacts the driver’s
seat, move the child restraint
system to a different seat. If it
cannot be installed in a different
seat (other than the driver’s seat),
adjust the front seat so that
contact does not occur.
102673
WARNING
 Even with advanced airbags, chil-
dren can be seriously injured by
the airbag. Seat children 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 not
restrained or improperly
restrained. Because children 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 systems
in the REAR seats at all times. You
should choose a restraint system
which is appropriate for the child’s
age, height and weight. According
to accident statistics, children are
safer when properly restrained in
the rear seating positions than in
the front seating positions. Do not connect tw o or more lower
hooks onto the same anchorage
(bar).

■Choosing a Child Restraint
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 appli-
cable requirements of Federal Motor
Vehicle Safety Standards for the United
States or of Canada Motor Vehicle Safety
Standards for Canada. It can be identified
by looking for the label on the child
restraint system or the manufacturer's
statement of complia nce in the document
attached to the system. Al so it is important
for you to make sure that the child restraint
system is compatible with the vehicle in
which it will be used.
NOTESome sizes of child restraint systems
may not fit the vehicle seat. Before
purchasing a child restraint system,
check whether it fits on the vehicle
seat.
WARNING
 SINCE YOUR VEHICLE IS
EQUIPPED WITH A
PASSENGER’S SRS AIRBAG,
NEVER INSTALL A CHILD
RESTRAINT SYSTEM IN THE
FRONT PASSENGER’S SEAT.
DOING SO RISKS SERIOUS
INJURY OR DEATH TO THE
CHILD BY PLACING THE CHILD’S
HEAD TOO CLOSE TO THE SRS
AIRBAG. Do not allow children to lean their
heads or any other parts of their
bodies against the door or the
area of the seat, front and rear
pillars or roof side rails. The SRS
side airbags and SRS curtain
airbags deploy even if children
are seated in the child restraint
system, and the impact could
cause death or serious injury to
the child. To secure the child restraint
system, be sure to comply with all
installation instructions provided
by the child restraint system
manufacturer. Not doing so could
result in death or serious injury to
children in a sudden stop or acci-
dent.
