CAUTION■
Front passenger occupant classi fication 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 ligh t to be illuminate d, which indicates
that the passenger’s airbags will not deploy in the event of a severe accident. If the
seatback touches the rear se at, return the seatback to a position where it does
not touch the rear seat. Keep the front pa ssenger 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 se at, the “AIR BAG ON” indicator light is illu-
minated. If the “AIR BAG OFF” indicator is illuminated, 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 still rema ins illuminated, either ask the pas-
senger to move to the rear seat, or if th at is not possible, move the front passenger
seat fully rearward.●
When it is unavoidable to install the forw ard-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. 141)●
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 indicate 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 use a seat accessory, such as a cushion or seat cover, that covers the seat
cushion surface.●
Do not modify or replace the upholstery of the front seat.
