The "PASS AIRBAG" light never illuminates in my car. I read the manual (page 37) and airbag is disabled when a rear facing infant seat, a forward-facing child restraint, or a booster seat is detected or when the passenger seat is empty. Have you ever seen your light say the airbag is off? I'm thinking it's OK, because the manual also has this table. Occupant Passenger Airbag OFF Indicator Passenger Airbag Empty Unlit Disabled Child Lit Disabled Adult Unlit Enabled So if the passenger seat is empty, the light will be unlit, but the airbag is still disabled (this seems to contradict the previous statement ...)
