'04 4Runner_U (L/O 0308) -Seat belt pretensioners The seat belt pretensioners will not operate in a vehicle rollover if the "RSCA OFF" indicator light is on. For details, see "Roll sensing of curtain shield airbags off switch" on page 87 in this Section. The driver and front passenger seat belt pretensioners are designed to be activated in response to a severe frontal impact or a vehicle rollover. When the sensor detects a severe frontal impact or a vehicle rollover, the front seat belts are quickly drawn back by the retractors so that the belts snugly restrain the occupants. The seat belt pretensioners are activated even with no passenger in the front seat. The seat belt pretensioners and SRS airbags may not operate together in all collisions.
