'06 AVALON_U (L/O 0508) 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 "-Front passenger occupant classification system" on page 94 in this Section.) The seat belt pretensioners and SRS airbags may not operate together in all collisions. The seat belt pretensioner system consists mainly of the following components, and their locations are shown in the illustration. 1. Front airbag sensors 2. SRS warning light 3. "AIRBAG ON" and "AIRBAG OFF" indicator lights 4. Front passenger occupant classification system (ECU and sensors) 5. Seat belt pretensioner assemblies 6. Front passenger's switch seat belt buckle The seat belt pretensioners are controlled by the airbag sensor assembly. The airbag sensor assembly consists of a safing sensor and airbag sensor. When the seat belt pretensioners are activated, an operating noise may be heard and a small amount of non- toxic gas may be released. This does not indicate that a fire is occurring. This gas is normally harmless. Once the seat belt pretensioners have been activated, the seat belt retractors remain locked. CAUTION Do not modify, remove, strike or open the seat belt pretensioner assemblies, airbag sensor or surrounding area or wiring. Failure to follow these instructions may prevent the seat belt pretensioners from activating correctly, cause sudden operation of the system or disable the system, which could result in death or serious injury. Consult your Toyota dealer about any repair and modification. 7. Airbag sensor assembly 77
