Pretensioners are designed to func-
tion on a one-time-only basis. In the
event that a pretensioner is acti-
vated, both the driver’s and front
passenger’s seatbelt retractor as-
semblies should be replaced only
by an authorized SUBARU dealer.
When replacing seatbelt retractor
assemblies, use only genuine
SUBARU parts.
If a seatbelt that has a seatbelt
pretensioner does not retract or
cannot be pulled out due to a mal-
function or activation of the preten-
sioner, contact your SUBARU dealer
as soon as possible.

To obtain maximum protection,
the occupants should sit in an
upright position with their seat-
belts properly fastened. Refer to
“Seatbelts” �P48.
Do not modify, remove or strike
the seatbelt retractor assemblies
equipped with seatbelt preten-
sioners or surrounding area. This
could result in accidental activa-
tion of the seatbelt pretensioners
or could make the system inop-
erative, possibly resulting in ser-
ious injury. Seatbelt preten-
sioners have no user-serviceable
parts. For required servicing of

follows.
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 adaptive force limiter will select a
reducing load to the suit body size of
occupant as detected by the occupant
detection system sensors.

NOTE
This section is applicable to the front
seatbelt.
If the sensor detects a certain predeter-
mined amount of force during frontal or
side collisions or rollover accidents, any
seatbelt that has a seatbelt pretensioner is
quickly drawn back in by the retractor to
take up the slack so that the belt more
effectively restrains the seat occupant.
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.
The rear passenger’s seatbelt (window-
side) pretensioner includes a tension
reducing device which limits the peak
forces exerted by the seatbelt on the
occupant in the event of a collision.
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.

& System monitors
Lap belt pretensioner
A diagnostic system continually monitors
the readiness of the seatbelt pretensioner
with the ignition switch in the “ON” position.
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. For details, refer to “SRS airbag
system monitors” �P105.
The shoulder belt pretensioner is supple-
mented 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 restrains the front seat
occupant more effectively.
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.

Tampering with or disconnecting
the system’s wiring could result
in accidental activation of the
seatbelt pretensioner and/or
