Seatbelt Pretensioners 53
The shoulder belt pretensioner is supplemented 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.
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 collision.
The adaptive force limiter will select a reducing load to suit the body size of 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 pretensioner remains locked. Consequently, the seatbelt cannot be pulled out and retracted and therefore must be replaced.
& System Monitors s01af03
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” FP99.
& System Servicing
WARNING
s01af04
. 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 electrical 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“ Components” FP79.
If you need service or repair in those areas or near the front seatbelt retractors, have the work performed by your authorized SUBARU dealer.
NOTE
If the front or side 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.
