The following seatbelts have a seatbelt pretensioner.
NOTE
The pretensioner sensor also serves as follows.
WARNING
When the seatbelt pretensioners are activated, an operating noise will sound 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.
Shoulder belt pretensioner
The shoulder belt pretensioner instantaneously pulls the belt to eliminate slack if a certain level of force is detected during frontal, side or rollover accidents. As a result, the seatbelt restrains the front seat occupant more effectively.
The front shoulder belt pretensioner includes a tension-reducing device that limits the peak forces exerted by the seatbelt on the occupant in the event of a collision.
The adaptive force limiter will reduce the load to suit the body size of the occupant as detected by the occupant detection sensor (front passenger’s seatbelt).
Lap belt pretensioner
The shoulder belt pretensioner is supplemented by a lap belt pretensioner, which is located at the base of the center pillar. The lap belt pretensioner instantaneously pulls 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 pretensioner sensor also serves as follows.
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 that 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.
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” P111.
WARNING
CAUTION
For the locations of the sensors and control modules, refer to “Components” P91. 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.
Always consult your SUBARU dealer if you want to install any accessory parts to your vehicle.
CAUTION
Do not perform any of the following modifications. Such modifications can interfere with the proper operation of the seatbelt pretensioners.
