SUBARU IMPREZA WRX 2007 3.G Service Manual

1-16Seat, seatbelt and SRS airbags
WARNING
Be sure to fasten both tongue plates
to the respective buckles. If the
seatbelt is used only as a shoulder
belt (with the connector ’s tongue
plate not fastened to the connec-tor ’s buckle on the right-hand side),
it cannot properly restrain the wear-
er in position in an accident, possi-
bly resulting in serious injury ordeath.
1. Remove the tongue plate from the belt
holder located under the right rear quarter
glass and pull out the seatbelt slowly.
2. After drawing out the seatbelt, pass it
through the belt guide as follows: First
insert one edge of the belt into the open
gap in the belt guide; then slide the rest of
the belt in, so that the whole belt fitsinside.
3. After confirming that the webbing is not
twisted, insert the connector (tongue)
attached at the webbing end into the
buckle on the right-hand side until a click
is heard.
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 slowlyagain.
4. Insert the center seatbelt tongue plate
into the center seatbelt buckle marked“ CENTER ”on the left-hand side until it
clicks.

5. To make the lap part tight, pull up on
the shoulder belt.
6. Place the lap belt as low as possible
on your hips, not on your waist. !Unfastening the seatbelt
Push the release button of the center
seatbelt buckle (on the left-hand side) to
unfasten the seatbelt. NOTE
When the seatback is folded down for
greater cargo area, it is necessary to
disconnect the connector.
1. Insert a key or other hard pointed
object into the slot in the connector
(buckle) on the right-hand side and push
it in, and the connector (tongue) plate will
disconnect from the buckle.
2. Allow the retractor to roll up the belt. Seat, seatbelt and SRS airbags

1-18Seat, seatbelt and SRS airbags
You should hold the webbing end and
guide it back into the retractor while it is
rolling up. Insert the connector (tongue)
into the belt holder.
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 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. Seatbelt extender
If the front seatbelts are not long enough
to permit the tongue plate to engage with
the seatbelt buckle, an optional seatbelt
extender is available from your SUBARU
dealer. When ordering an extender, only
order one particularly designed for your
vehicle. Several different types of exten-
ders are available to match various
varieties of front seatbelt designs. See
your SUBARU dealer for assistance.
The extender adds approximately 8
inches (200 mm) of length and it can be
used for either the driver or front passen-
ger seating position.
For the safety of others, the extender
should be removed after each use, espe-
cially if the next person using the seatbelt
does not need one.
Note that leaving the seatbelt extender
’s
tongue plate engaged with the seatbelt
buckle may prevent the Subaru advanced
frontal airbag system from functioning
correctly or cause the system to fail.
WARNING
Be sure to observe the following
when using the seatbelt extender.
Failure to follow these instructions

and warnings could reduce the
effectiveness of the seatbelt and
result in more serious injury in the
event of a collision. .Never use the extender when the
belt itself is long enough to
permit it to be buckled properly.
If removal of heavy clothing is all
that is needed to permit the
seatbelt to be buckled properly,
remove the heavy clothing and
do not use the extender.
. Do not use the extender if the
buckle of the extender rests over
the abdomen.
. Do not let someone else use the
extender. Use of an extender
when it is not needed could
reduce the effectiveness of the
seatbelt and result in more ser-
ious injury in the event of acollision.
. Use the extender only for the
front seatbelts and only for the
model for which it was originally
provided. Never use the extender
for the rear seatbelts or for a
different model. NOTE
When the seatbelt extender is used by
a pregnant passenger, consult a doctor
to get approval in advance.
To connect the extender to the seatbelt,
insert the tongue plate into the seatbelt
buckle so that the
“PRESS ”signs on the
buckle-release buttons of the extender
and the seatbelt are both facing outward
as shown in the diagram. You will hear a
click when the tongue plate locks into thebuckle.
When releasing the seatbelt, press on the
buckle-release button on the extender, not
on the seatbelt. This helps to prevent
damage to the vehicle interior and ex-
tender itself. 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 frontalcollision.
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
1-19
– CONTINUED –

1-20Seat, 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 him
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 tothe “Seatbelts ”section in this
chapter.
. 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 monitors
A 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. The
SRS airbag system warning light will show
normal system operation by lighting for
approximately 6 seconds when the igni-

tion switch is turned to the“ON ”position.
The following components are monitored
by the indicator: . Front sub sensor (Right-hand side)
. Front sub sensor (Left-hand side)
. Airbag control module (including im-
pact sensors). Frontal airbag module (Driver ’s side)
. Frontal airbag module (Front passen-
ger ’s side)

WARNING
If the warning light exhibits any of
the following conditions, there may
be a malfunction in the seatbelt
pretensioners and/or SRS airbag
system. Immediately take your vehi-
cle to your nearest SUBARU dealer
to have the system checked. Unless
checked and properly repaired, the
seatbelt pretensioners and/or SRS
airbag will not operate properly in
the event of a collision, which may
increase the risk of injury. . Flashing or flickering of the warn-
ing light

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. The wir-
ing harnesses of the seatbelt
pretensioner and SRS airbag
systems are covered with yellow
insulation and the connectors of
the system are yellow for easy
identification. Do not use electri-
cal test equipment on any circuit
related to the seatbelt preten-
sioner and SRS airbag systems.
For required servicing of the
seatbelt pretensioner, see your
nearest SUBARU dealer.

CAUTION
The front sub sensors are located in
both front fenders 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, we recom-
mend that you have an authorized
SUBARU dealer perform the work.
NOTE
If 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 modification
Always 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 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 covered under the section in
this manual, entitled “Installation of child
restraint systems by use of lower and
tether anchorages (LATCH) ”).
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 ismoving.
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 system
The following are SUBARU ’s recommen-
dations on where to place a child restraint
system in your vehicle.
Seat, seatbelt and SRS airbags 1-23
– CONTINUED –

1-24Seat, seatbelt and SRS airbags
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 thepassenger ’s airbag.
B: Rear seat, window-side seatingpositions
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) 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 thechild ’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.
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 ’S HEAD TOO CLOSE TO
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 beused. &
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.
! Installing a rearward facing childrestraint
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. Seat, seatbelt and SRS airbags
