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 which 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
S01AF0203
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 .

NOTE
This section is applicable to the following components .
. second-row ( window-side ) seatbelt
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 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 .
& 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 ” FP110 .
