On certain passenger vehicles equipped with a front passenger power seat, when installing certain rear-facing infant child seat bases onto the seat with an excessively high seatbelt tension, it may be possible to unseat a component called the buckle status switch from the seat belt buckle.
リスク: If the switch becomes unseated, the front passenger occupant classification system may mistake the rear-facing child restraint for an unbelted adult occupant, and may not suppress the deployment of the front passenger airbag.
対策: Dealers will replace the front passenger seatbelt buckle status switch. This safety improvement campaign (ssc 40m) began on december 20, 2004. Owners should contact toyota at 1-800-331-4331 or lexus at 1-800-255-3987..
