LS600hL_U(OM50E41U)
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. 66)
●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 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.

■Head restraint precautions
Observe the following precautions regarding the head restraints. Failure to do so
may result in death or serious injury.
●Use the head restraints designed for each respective seat.
●Adjust the head restraints to the correct position at all times.
●Do not drive with the head restraints removed.
■The active head restraint on the front passenger seat
Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which may prevents the sensor from
detecting the passenger’s weight properly . As a result, the active head restraint
may not activate in the event of an accident.
■Active head restraint precautions
●Do not put head restraint covers.
●For removal, installation, modification, disassembly or disposal of the active head
restraints, contact your Lexus dealer.
Inappropriate handling of th e active head restraints may prevent them from oper-
ating properly during an accident.
