Front Seats
301-1. Front Seats
WARNING
Never adjust the seat while
driving, as personal injury or loss
of vehicle control may occur. Before adjusting the seat, ensure
nothing is blocking the adjusting
mechanism. After adjusting the seat, move it
back and forth to ensure the seat
is securely locked. If it is not, it
may move suddenly or the
seatbelt may not operate prop-
erly. Do not put objects under the front
seats. They may interfere with
front seat locking mechanism
and cause an accident.
 Seatbelts provide maximum
restraint when the occupant sits
back and upright in the seat. To
reduce the risk of sliding under
the seatbelt in a collision, the
front seatbacks should always be
used in the upright position while
the vehicle is running. If the front
seatbacks are not in the upright
position and a collision occurs,
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
injury or death. The SRS airbags deploy with
considerable speed and force.
Occupants who are not sitting
back and upright when the SRS
airbag deploys could suffer
serious injury. Because the SRS
airbag needs enough space for
deployment, the driver should
always sit upright and well back
in the seat as far from the steering
wheel as practical while still
maintaining full vehicle control,
and the front passenger should
move the seat as far back as
possible and sit upright and well
back in the seat.

WARNING
 Never drive the vehicle with the
head restraints removed because
they are designed to reduce the
risk of serious neck injury in the
event that the vehicle is struck
from the rear. Also, never install
the head restraints backwards.
Doing so will prevent the head
restraints from functioning as
intended. Therefore, when the
head restraints are removed, all
head restraints must be rein-
stalled properly to protect vehicle
occupants. The vehicle should not be oper-
ated until the head restraints are
installed in their proper positions.

Seatbelts
40This vehicle is equipped with a crash
sensing and diagnostic module, which will
record the use of the seatbelt by the front
passenger when any of the SRS frontal,
side and curtain airbags deploys.▼ Infants or small children
Use a child restraint system that is suit-
able for this vehicle. Refer to "Child
Restraint Systems" P46.
▼ Children
If a child is too big for a child restraint
system, the child should sit in the rear seat
and be restrained using the seatbelts. According to accident statistics, children

are safer when properly restrained in the
rear seating positions than in the front
seating positions. Never allow a child to
stand up or kneel on the seat.
If the shoulder portion of the belt crosses
the face or neck, move the child closer to
the belt buckle to help provide a good
shoulder belt fit. Care must be taken to
securely place the lap belt as low as
possible on the hips and not on the child’s
waist. If the shoulder portion of the belt
cannot be properly positioned, a child
restraint system should be used. Never
place the shoulder belt under the child’s
arm or behind the child’s back.
▼ Expectant mothers
Expectant mothers also need to use the
seatbelts. They should consult their doctor for specific recommendations. The lap

belt should be worn securely and as low
as possible over the hips, not over the
waist.
■ Emergency Locking
Retractor (ELR)The driver’s seatbelt has an Emergency
Locking Retractor (ELR).
The emergency locking retractor allows
normal body movement but the retractor
locks automatically during a sudden stop,
impact or if you pull the belt very quickly
out of the retractor.■ Automatic Locking
Retractor/Emergency
Locking Retractor (ALR/ELR)Each passenger’s seatbelt has an Auto-
matic Locking Retractor/Emergency
Locking Retractor (ALR/ELR). The Auto-
matic Locking Retractor/Emergency
Locking Retractor normally functions as
an Emergency Locking Retractor (ELR).
The ALR/ELR has an additional locking
mode, “Automatic Locking Retractor
(ALR) mode”, intended to secure a child
restraint system.
The ALR mode functions as follows.
When the seatbelt is once drawn out
completely and is then retracted even
NEVER INSTALL A CHILD
RESTRAINT SYSTEM IN THE
FRONT SEAT. DOING SO RISKS
SERIOUS INJURY OR DEATH TO
THE CHILD BY PLACING THE
CHILD’S HEAD TOO CLOSE TO
THE SRS AIRBAG.According to accident statistics,
children are safer when properly
restrained in the rear seating
positions than in the front seat-
ing positions. For instructions
and precautions concerning the
child restraint system, refer to
"Child Restraint Systems" P46.

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.■ Seatbelt Warning Light
and Chime Refer to "Seatbelt Warning Light and
Chime" P131.
■ 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.

Seatbelt Pretensioners
45
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 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.
