CAUTION
●Do not place your hands on the back door damper stay to close the back
door, and do not hang on the back door damper stay.
Doing so may cause hands to be caught or the back door damper stay to
break, causing an accident.
● If a bicycle carrier or similar heavy object is attached to the back door, it
may fall closed again after being opened, causing someone’s hands, head
or neck to be caught and injured. When installing an accessory part to the
back door, using a genuine Toyota part is recommended.
●When closing the back door, take extra
care to prevent your fingers etc. from
being caught.
● When closing the back door, make sure
to press it lightly on its outer surface. If
the back door handle is used to fully
close the back door, it may result in
hands or arms being caught.

Back door closer (if equipped)
● Use caution when using the back door closer as it still operates when the
power back door system is canceled.
■ Power back door (if equipped)
Observe the following precautions when operating the power back door.
Failure to do so may cause death or serious injury.
● Check the safety of the surrounding area to make sure there are no obsta-
cles or anything that could cause any of your belongings to get caught.
● If anyone is in the vicinity, make sure they are safe and let them know that
the back door is about to open or close.
● If the operating conditions of the power back door are no longer met, a
buzzer may sound and the back door may stop opening or closing. The
back door then has to be operated manually. Take extra care when on an
incline, as the back door may open or close abruptly.
● On an incline, the back door may fall after it opens. Make sure the back
door is fully open and secure.
●In the event that the back door is left
slightly open, the back door closer will
automatically close it to the fully closed
position. It takes several seconds
before the back door closer begins to
operate. Be careful not to catch fingers
or anything else in the back door, as
this may cause bone fractures or other
serious injuries.

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

Seat belt pretensioners (front seats)
The pretensioner helps the seat
belt to quickly restrain the occu-
pant by retracting the seat belt
when the vehicle is subjected to
certain types of severe frontal
collision.
The pretensioner does not acti-
vate in the event of a minor frontal
impact, a side impact, a rear
impact or a vehicle rollover.
Pre-collision seat belts (front seats of vehicles with pre-collision
system)If the pre-collision sens or detects that a collision is unavoidable, the
pre-collision system w ill retract the seat belt , thus enhancing the
effectiveness of the seat be lt pretensioner in a crash.
The same will happen if the driver makes an emergency braking or loses
control of the vehicle. (P. 336)
■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may also
lock if you lean forward too quickly. A slow, easy motion will allow the belt to
extend so that you can move around fully.
■ Automatic locking retractor (ALR)
When a passenger’s shoulder belt is completely extended and then
retracted even slightly, the belt is locked in that position and cannot be
extended. This feature is used to hold the child restraint system (CRS) firmly.
To free the belt again, fully retract the belt and then pull the belt out once
more. ( P. 194)

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.
