For safety and security
CAUTION
■Front passenger occupant classification system precautions
●Do not recline the front passenger seatback so far that it touches a rear seat. This
may cause the “AIR BAG OFF” indicator light to be illuminated, which indicates
that the passenger’s airbags will not deploy in the event of a severe accident. If the
seatback touches the rear seat, return th e seatback to a position where it does
not touch the rear seat. Keep the front passenger seatback as upright as possible
when the vehicle is moving. Reclining the seatback excessively may lessen the
effectiveness of the seat belt system.
●If an adult sits in the front passenger seat, the “AIR BAG ON” indicator light is illu-
minated. If th e “AIR BAG OFF” indicator is illumi nated, ask the passenger to sit
up straight, well back in the seat, feet on the floor, and with the seat belt worn cor-
rectly. If the “AIR BAG OFF” indicator stil l remains illuminated, either ask the pas-
senger to move to the rear seat, or if that is not possible, move the front passenger
seat fully rearward.
●When it is unavoidable to install a forward-facing child restraint system on the
front passenger seat, install the child rest raint system on the front passenger seat
in the proper order. ( P. 5 9 )
●Do not modify or remove the front seats.
●Do not kick the front passenger seat or subject it to severe impact. Otherwise,
the SRS warning light may come on to indi cate a malfunction of the detection sys-
tem. In this case, contact your Lexus dealer immediately.
●Child restraint systems installed on the rear seat should not contact the front seat-
backs.
●Do not modify or replace the upholstery of the front seat.
