the airbags with non-toxic gas to he lp restrain the motion of the occu-
pants.

CAUTION
■Front passenger occupant classification system precautions
●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 remain 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 a 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. 155)
●Do not modify or remove the front seat.
●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 in the detection sys-
tem. In this case, contact your Lexus dealer immediately.
●Child restraint systems installed on the second seat should not contact the front
seatbacks.
●Do not use a seat accessory, such as a cushion and seat cover, that covers the
seat cushion surface.
●Do not modify or replace the upholstery of the front seat.
