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
