Occupant Classification System: Precaution: Precaution

WARNING: This page is about a different car, the 2011 Lexus IS 350 and 2011 Lexus IS 250. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:

Do not use seat accessories (such as cushions or covers) that cover the front seat. Also, do not modify or replace the upholstery of the front seat. Doing so may prevent the front passenger airbag system from activating correctly, disable the system or cause the front passenger airbag to inflate accidentally, and result in death or serious injury.

NOTE:

Replace the occupant classification ECU, occupant detection sensor, seat cushion cover pad, seat cushion cover and seat cushion seat heater as a 5 part set. See supply set part no.
