Seatbelt Safety Tips
102759
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.All belts should fit snugly in order
to provide full restraint. Loose
fitting belts are not as effective in
preventing or reducing injury.Each seatbelt is designed to
support only one person. Never
use a single belt for two or more
persons – even children. Other-
wise, in an accident, serious
injury or death could result.
Replace all seatbelt assemblies
including retractors and
attaching hardware worn by
occupants of a vehicle that has
been in a serious accident. Also,
be sure to replace seatbelt
assemblies that show signs of
severe fraying or having been
cut. The entire assembly should
be replaced even if damage is not
obvious.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 chil-
dren, 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, we strongly recommend
that ALL children (including
those in child restraint systems)
sit in the REAR seat properly
restrained at all times in a child
restraint system or in a seatbelt,
whichever is appropriate for the
child’s height and weight. Secure
ALL types of child restraint
systems in the REAR seats at all
times.

slightly, the retractor locks the seatbelt in
that position and the seatbelt cannot be
extended. As the belt is rewinding, clicks
will be heard which indicate the retractor
functions as an ALR. When the seatbelt is
retracted fully, the ALR mode is canceled
and the ELR mode is restored.
When securing a child restraint system on
the rear seats by using a seatbelt, the
seatbelt must be changed over to the
Automatic Locking Retractor (ALR) mode.
For instructions on how to install the child
restraint system using a seatbelt, refer to
"Installing Child Restraint Systems with
ALR/ELR Seatbelt" P51.
When the child restraint system is
removed, make sure that the retractor is
restored to the Emergency Locking
Retractor (ELR) mode by allowing the
seatbelt to retract fully.■

Fastening the Seatbelt
WARNING
 Never use a belt that is twisted or
reversed. In an accident, this can
increase the risk or severity of
injury.Keep the lap belt as low as
possible on your hips. In a colli-
sion, this spreads the force of the
lap belt over stronger hip bones
instead of across the weaker
abdomen.Seatbelts provide maximum
restraint 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 colli-
sion, 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 or death.
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.

Seat, Seatbelt and SRS Airbags1
– CONTINUED –
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 passenger’s seatbelt
with Shoulder Belt Preten-
sioner
The pretensioner sensor also serves as
follows.
 Front impact sensor
 Side impact sensor
 Door 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 passenger’s seatbelt
pretensioner includes a tension reducing
device which limits the peak forces
exerted by the seatbelt on the occupant in
the event of a collisi on. The 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 can
not be pulled out and retracted and there-
fore must be replaced.
■
System Monitors
A 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" 

Seat, Seatbelt and SRS Airbags1
– CONTINUED –
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
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).

Installation of Child Restraint
Systems by Use of Lower
and Tether Anchorages
(LATCH)
▼
Lower and tether anchorages
NOTEThe seatbelt warning system of the
rear seats detects if any of the seats
are occupied by a passenger. Install-
ing a child restraint system in the rear
seating area, using the LATCH
anchors, may result in the activation of
the passenger seatbelt warning light
and chime. Fastening the rear seatbelt
prior to installing the child restraint
system will avoid activating the pas-
senger seatbelt warning light and
chime. For details, refer to "Rear pas-
senger’s seats" 
P133
Some types of child restraint systems can
be installed on the rear seat of your
vehicle without use of the seatbelts. Such
child restraint systems are secured to the
dedicated anchorages provided on the
vehicle body.
The lower and tether anchorages are
sometimes referred to as the LATCH
system (L ower Anchors and T ethers for
CHildren). Your vehicle is equipped with four lower
anchorages (bars) and two upper anchor-
ages (tether anchorages) for accommo-
dating such child restraint systems.
WARNING

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.
102674
When installing a child restraint
system using LATCH anchors
with the rear seatbelt fastened,
ensure that the rear seatbelt does
not become caught in the child
restraint system or the lower
LATCH anchorages.

General Precautions
regarding SRS Airbag
System and Children
Do not attach a hands-free micro-
phone or any other accessory to a
front pillar, a center pillar, a rear
pillar, the windshield, a side
window, or any other cabin
surface that would be near a
deploying SRS curtain airbag. A
hands-free microphone or other
accessory in such a location
could be propelled through the
cabin with great force by the
curtain airbag, or it could prevent
correct deployment of the curtain
airbag. In either case, the result
could be serious injuries.
101973
WARNING
Do not put any kind of clothes or
other objects over the front
seatback and do not attach labels
or stickers to the front seat
surface on or near the SRS side
airbag. They could prevent
proper deployment of the SRS
side airbag, reducing protection
available to the front seat’s occu-
pant.Do not install a seat cover unless
it is a genuine SUBARU seat
cover exclusively designed for
use with the SRS airbag. Even
when using a genuine SUBARU
seat cover, the SRS side airbag
system may not function
normally if the seat cover is not
installed correctly.
WARNING
Seat children in the rear seat prop-
erly 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 deploy-
ment is greater.

Front passenger’s SRS frontal
airbag
The front passenger’s SRS frontal airbag
uses a dual stage inflator. The inflator
operates in different ways depending on
the severity of impact.
1) Occupant detection sensorsThe occupant detection system sensors
are installed between the seat and seat
rails, and monitor the physique and
posture of the front passenger. Using this
information, the occupant detection
system determines whether the front
passenger’s SRS frontal airbag should be
deployed or not.
The occupant detection system may not
inflate the front passenger’s SRS frontal
airbag even when the driver’s SRS frontal
airbag deploys. This is normal. In this
case, although the front passenger’s SRS
frontal airbag does no t operate, the front
passenger’s seatbelt pretensioner oper-
ates with the driver’s seatbelt
pretensioner. For details about the seatbelt pretensioner, refer to "Seatbelt
Pretensioners"
P44.
