Seat, seatbelt and SRS airbags/Front seatbelt pretensioners
ted 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 or side collision force or a
rollover accident is detected. As a result,
the seatbelt restrains the front seat occupant more effectively.
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 pretensioner remains locked. Consequently, the seatbelt
cannot be pulled out and retracted and
therefore must be replaced.
NOTE
. Seatbelt pretensioners are not designed to activate in minor impacts or
in rear impacts.
. In cases of rollover accidents, the
lap belt pretensioner does not activate;
however, as the curtain airbags deploy,
the driver’s side seatbelt pretensioner
and front passenger’s side shoulder
belt pretensioner are activated simulta-
neously.
. In cases of frontal collisions, the
following components will operate simultaneously.
– Seatbelt pretensioner for driver
– Seatbelt pretensioners for front
passenger
– SRS frontal airbag for driver
– SRS frontal airbag for front passenger*
– SRS side airbags (both sides) (if
an offset frontal collision occurs)
– SRS curtain airbags (both sides)
(if an offset frontal collision occurs)
*: This does not operate if the occupant
detection system deactivates airbag operation. For details, refer to “Front
passenger’s SRS frontal airbag” F1-51.
. In cases of side collisions, the
following components will operate simultaneously.
– SRS curtain airbag (impacted
side)
– SRS side airbag (impacted side)
(when both the satellite safing sensor and any of the center pillar
impact sensors/front door impact
sensors sense an impact force)
– Seatbelt pretensioner for driver
(when both the satellite safing sensor and the driver’s side front door
1-27
impact sensor sense an impact
force)
However, when a center pillar impact sensor detects a signal faster
than the front door impact sensor,
or both sensors detect signals
simultaneously, the seatbelt pretensioner does not activate.
– Seatbelt pretensioner for front
passenger (shoulder belt pretensioner only) (when both the satellite
safing sensor and the front passenger’s side front door impact sensor
sense an impact force)
However, when a center pillar impact sensor detects a signal faster
than the front door impact sensor,
or both sensors detect signals
simultaneously, the seatbelt pretensioner does not activate.
. Pretensioners are designed to function 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 should
be replaced only by an authorized
SUBARU dealer. When replacing seatbelt 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
