Seatbelt Pretensioners 53 |
||||||
|
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 suit the 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 .

& 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 ” FP99 .
