Seatbelt pretensioners 67
& Seatbelt with shoulder belt pretensioner
S01AF12
NOTE
This section is applicable to the following components .
. second-row ( window-side ) seatbelt
If the sensor detects a certain predetermined 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 second-row seatbelt ( window-side ) pretensioners include 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 .
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 .
& 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 ” FP114 .
& 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 ” FP94 .
If you need service or repair in those areas or near the seatbelt retractors , have the work performed by your authorized SUBARU dealer .
