Seat, seatbelt and SRS airbags / Seatbelt pretensioners
. Side impact sensor. Front door impact sensor. Rollover sensor
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 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 retractor remains locked. Consequently, the seatbelt can not be pulled out and retracted and therefore must be replaced.

& Seatbelt with shoulder belt and lap belt pretensioners
S01AF02
NOTE
This section is applicable to the front passenger’ s side seatbelt.
1) Seatbelt retractor assembly( shoulder belt pretensioner and adaptive force limiter)
2) Lap belt pretensioner
On the front passenger’ s side, 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 the suit 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.
