OCCUPANT RESTRAINT SYSTEM Seat belt pretensioners The outboard rear seat belt pretensioners are activated even with no passenger in the outboard rear seats. The seat belt pretensioners and SRS airbags may not operate together in all collisions. 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 retractors so that the belts snugly restrain the occupants. The front passenger's seat belt pretensioner will not activate if no passenger is detected in the front passenger seat by the front passenger occupant classification system. However, the front passenger's seat belt pretensioner may activate if luggage is put on the seat, or the seat belt is buckled up regardless of the presence of an occupant in the seat. (As for the front passenger occupant classification system, see page 134.) 110
