CAUTION
■Front passenger occupant classification system precautions
●Do not recline the front passenger seatback so far that it touches the rear seat. This
may cause the “AIR BAG OFF” indicator light to be illuminated, which indicates that
the SRS airbags for the front passenger will not deploy in the event of a severe acci-
dent. If the seatback touches the rear seat, return the seatback to a position where it
does not touch the rear seat. Keep the fron t passenger seatback as upright as possi-
ble 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 illumi-
nated. 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 correctly. If
the “AIR BAG OFF” indicator still remains illuminated, either ask the passenger 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 restraint sy stem on the front passenger seat in the
proper order. ( P. 5 8 )
●Do not modify or remove the front seats.
●Do not kick the front passenger seat or subj ect it to severe impact. Otherwise, the
SRS warning light may come on to indicat e a malfunction of the front passenger
occupant classification system. In this ca se, 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 cu shion and seat cover, that covers the seat
cushion surface.
●Do not modify or replace the upholstery of the front seat.
●Do not place anything between the cons ole box and front passenger seat. Other-
wise, the system may not detect the front passenger properly, leading to improper
operation of the airbags.
●Adjust the front passenger seat so that the head restraint does not touch the ceiling. If
the head restraint is left in contact with th e ceiling, the system may not detect the front
passenger properly, leading to im proper operation of the airbags.

■Seat adjustment
To reduce the risk of sliding under the lap belt during a collision, do not recline the seat
more than necessary.
If the seat is too rec lined, the lap belt may slide past the hips and apply restraint forces
directly to the abdomen, or your neck may contact the shoulder belt, increasing the risk
of death or serious injury in the event of an accident.
Adjustments should not be ma de while driving as the seat may unexpectedly move and
cause the driver to lose control of the vehicle.
