Seat, seatbelt and SRS airbags/Seatbelt pretensioners your SUBARU dealer. . When discarding seatbelt retrac- tor assemblies equipped with seatbelt pretensioners or scrap- ping the entire vehicle due to collision damage or for other reasons, consult your SUBARU dealer. NOTE . Seatbelt pretensioners are not de- signed to activate in minor impacts or in rear impacts. . Pretensioners are designed to func- tion 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 seat- belt 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 malfunction or activation of the pretensioner, contact your SUBARU dealer as soon as pos- sible. . If the seatbelt retractor assembly or surrounding area has been damaged, contact your SUBARU dealer as soon as possible. . When you sell your vehicle, we urge you to explain to the buyer that it has seatbelt pretensioners by alerting the buyer to the contents of this section. & Seatbelt with shoulder belt pretensioner NOTE This section is applicable to the follow- ing components. . Driver’s seatbelt 1-21 . Front 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 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. The driver’s seatbelt pretensioner in- cludes a tension reducing device which limits the peak forces exerted by the seatbelt on the occupant in the event of a collision. 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. Front seatbelt pretensioner 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. The pretensioner sensor also serves as follows. . SRS frontal airbag sensor .
