Seatbelt Pretensioners
. Adaptive force limiter
The front passenger’ s side adaptive force limiter will select a reducing load to the suit body size of the 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 retractor remains locked. Consequently, the seatbelt cannot be pulled out and retracted and therefore must be replaced.
& Seatbelt with Shoulder Belt and Lap Belt Pretensioners

NOTE
This section is applicable to the driver’ s seatbelt.
1 Seatbelt retractor assembly( shoulder belt pretensioner)
2 Lap belt pretensioner
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 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 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 driver’ 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.
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
