■Power third seat
● If the indicator light above the switches flashes three times when the fold-
ing/returning switch is pressed, the folding operation will not start. Make
sure the shift lever is in P.
● If any of the following conditions occur while the seat is operating, the
seat operation will stop. The indicator light above the switches will flash
three times and a beep will sound for about 10 seconds:
• An object is caught between the seatback and seat cushion.
• The stowing switch is released.
• Other power third seat switch is pushed while operating the stowing
switch.
• The shift lever is moved from P when the engine switch is turned to the “ON” position (vehicles without a smart key system) or the “ENGINE
START STOP” switch is in IGNITION ON mode (vehicles with a smart
key system).
If the engine is started during operating, the seat operation may also be
stopped.
To continue the folding operation, the seatback must be returned to its
original position first.
■ AUTO ACCESS SEAT (if equipped)
The AUTO ACCESS SEAT cannot be removed.
■ “3RD SEAT” warning light (vehicles with power third seat)
The warning light comes on if the third
seat operation is not yet complete when
the engine switch is turned to the “ON”
position (vehicles without a smart key
system) or the “ENGINE START STOP”
switch is in IGNITION ON mode (vehicles
with a smart key system).

CAUTION
■When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, it may lead to choking or other serious injuries
that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
■ Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your
shoulder. The belt should be kept away from your neck, but not falling off
your shoulder. Failure to do so could reduce the amount of protection in an
accident and cause death or serious injuries in the event of a sudden stop,
sudden swerve or accident. ( P. 129)
■ Seat belt pretensioners
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the seat belt
pretensioner for the front passenger’s seat may not activate in the event of
a collision.
● If the pretensioner has activated, the SRS warning light will come on. In
that case, the seat belt cannot be used again and must be replaced at
your Toyota dealer.
