07 SIENNA_U (L/O 0612) If the front passenger occupant classification system determines that a person of adult size sits in the front passenger seat but the "AIRBAG OFF" indicator light is illuminated, one of the following is likely to have occurred: D A rear passenger lifts the front passenger seat cushion with their legs. The "AIRBAG ON" and "AIRBAG OFF" indicator lights will be illuminated initially when the ignition key is turned to the "ON" position. After about 4 seconds, they will go off. After that, the front passenger occupant classification system operates and judges which indicator light be illuminated. D Objects are placed under the front passenger seat. D The front passenger seatback is in contact with the second seat. To ensure the system correctly detects an adult sitting in the front passenger seat, make sure the above do not occur. Make sure that the "AIRBAG ON" indicator light is illuminated when an adult is seated in the front passenger seat. If the "AIRBAG OFF" indicator light is illuminated, ask the passenger to sit up straight, well back in the seat, and with the seat belt worn correctly. If the "AIRBAG OFF" indicator light still remains illuminated, either ask the passenger to move to the rear seat, or if that is not possible, move the front passenger seat fully rearward. The SRS warning light and "AIRBAG OFF" indicator light will come on if there is a malfunction in the front passenger occupant classification system. 136 2007 SIENNA from Oct. '06 Prod. (OM45437U)
