1-44 Seat, seatbelt and SRS airbags/*SRS airbag (Supplemental Restraint System airbag) monitors the physique and posture of the front passenger. Using this information, the occupant detection system determines whether the front passenger’s SRS frontal airbag should be deployed or not. The occupant detection system may not inflate the front passenger’s SRS frontal airbag even when the driver’s SRS frontal airbag deploys. This is normal. In this case, although the front passenger’s SRS frontal airbag does not operate, the front passenger’s seatbelt pretensioner oper- ates with the driver’s seatbelt preten- sioner. For details about the seatbelt pretensioner, refer to “Front seatbelt pre- tensioners” F1-17. CAUTION Observe the following precautions. Failure to do so may prevent the SUBARU advanced frontal airbag system from functioning correctly or cause the system to fail. . Do not apply any strong impact to the front passenger’s seat such as by kicking. . Do not let rear passengers rest their feet between the front seat- back and seat cushion. . Do not spill liquid on the front passenger’s seat. If liquid is spilled, wipe it off immediately. . Do not remove or disassemble the front passenger’s seat. . Do not install any accessory (such as an audio amplifier) other than a genuine SUBARU acces- sory under the front passenger’s seat. . Do not place anything (shoes, umbrella, etc.) under the front passenger’s seat. . Do not use the front passenger’s seat with the head restraint re- moved. . Do not leave any articles on the front passenger’s seat or the seatbelt tongue and buckle en- gaged when you leave your ve- hicle. . Do not put sharp object(s) on the seat or pierce the seat uphols- tery. . Do not place a magnet near the seatbelt buckle and the seatbelt retractor. . Do not use front seats with their backward-forward position and seatback not being locked into place securely. If any of them are not locked securely, adjust them again. For adjusting procedure, refer to “Manual seat” F1-4 (models equipped with manual seats only). SRS airbag system warning light If the seatbelt buckle switch and/or front passenger’s occupant detection system have failed, the SRS airbag system warning light will illuminate.
