OCCUPANT RESTRAINT SYSTEMS Seat belt pretensioners G16016 G16015 " 1 2 3 4 5 6 7 Front airbag sensors Occupant detection sensor Front passenger's seat belt buckle switch Front seat belt pretensioner assembly SRS warning light Rear seat belt pretensioner assembly Airbag sensor assembly Both front seats and the two outboard rear seats are equipped with seat belt pretensioners and are designed to be activated in response to a severe frontal impact. When the sensor detects a severe frontal impact, the seat belts are quickly drawn back by the retractor so that the belts snugly restrain the occupants. The front passenger seat belt pretensioner will not activate if there is no passenger sitting in the front passenger seat. However, the front passenger seat belt pretensioner may activate if luggage is put in the seat, or the seat belt is buckled up regardless of the presence of the occupant in the seat. The outboard rear seat belt pretensioners are activated even with no passengers in the outboard rear seats. The seat belt pretensioners and SRS airbags may not operate together in all collisions. The seat belt pretensioner system consists mainly of the above components, and their locations are shown in the illustration. The seat belt pretensioners are controlled by the airbag sensor assembly. The airbag sensor assembly consists of a safing sensor and airbag sensor. 159
