'03 L/C U (L/O 0301) -Front seat belt pretensioners Collisions occurring at certain speeds and angles may cause the seat belt pretensioners and SRS airbags not to operate all together. The driver and front passenger's seat belt pretensioners are designed to be activated in response to a severe frontal impact or a vehicle rollover. When the airbag sensor detects the shock of a severe frontal impact or a vehicle rollover, the front seat belts are quickly drawn back by the retractor so that the belts snugly restrain the front seat occupants. The front seat belt pretensioners are activated even with no passenger in the front seat. Roll sensing of curtain shield airbags off indicator light The seat belt pretensioners will not operate in a vehicle rollover if the roll sensing of curtain shield airbags off indicator light is on.
