■Precautions for power seats (if equipped)
If a seat cover or seat cushion is used on a power seat, the power seat may not operate
properly.
Before folding the seatback of a power seat, make sure that the seat and area around the
seat is free of obstructions which may interfere the operation.
■Rear seatback jam protection function (power seat)
When folding or returning the seatback of a power seat, if an object is detected between
the seatback and seat cushion or behind the seatback, the seatback may stop or move in
the opposite direction slightly.
A buzzer will sound continuously when the se atback stops and intermittently when mov-
ing in the opposite direction.
■If a buzzer sounds continuous ly after a third-row seat seatback is completely folded
(RX450hL)
The power seat system may be malfunctioning or it may need to be initialized. To initialize
the system, perform the following procedure. (It is necessary to perform this procedure
with two people.)
Check that the seat is free of obstructions.
Press and hold the side switch of the luggage compartment side switch for the
seat which the buzzer is sounding.
Within 10 seconds of the performing th e above step, press the side switch of
the seat side switch 5 times.
When a buzzer sounds 3 times, release the luggage compartment side switch.
Press the side switch of the seat side switch until the seatback is folded com-
pletely.
A buzzer will sound twice when the operation is complete.
If the buzzer does not stop sounding even though the above procedure has been per-
formed, have the vehicle inspected by your Lexus dealer.

■When operating the rear seatback
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Make sure that passengers are clear of the rear seatback before operating it.

do not recline the seat more than necessary.
If the seat is reclined excessively, the la p 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 de ath or serious injury in the event of an accident.
●Adjustments should not be made while dr iving as the seat may unexpectedly move
and cause the driver to lose control of the vehicle.
