CAUTION
■
Operating the back door
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in death
or serious injury.
●Remove any heavy loads, such as snow and ice, from the back door
before opening it. Failure to do so may cause the back door to suddenly
shut again after it is opened.
● When opening or closing the back door, thoroughly check to make sure
the surrounding area is safe.
● 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.
● Use caution when opening or closing the back door in windy weather as it
may move abruptly in strong wind.
●The back door may suddenly shut if it is
not opened fully. It is more difficult to
open or close the back door on an
incline than on a level surface, so
beware of the back door unexpectedly
opening or closing by itself. Make sure
that the back door is fully open and
secure before using the luggage com-
partment.

■
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 suddenly shut 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.

CAUTION
Observe the following precautions to reduce the risk of injury in the event of
sudden braking, sudden swerving or an accident.
Failing to do so may cause death or severe injury.
■Wearing a seat belt
●Ensure that all passengers wear a seat belt.
● Always wear a seat belt properly.
● Each seat belt should be used by one person only. Do not use a seat belt
for more than one person at once, including children.
● Toyota recommends that children be seated in the rear seat and always
use a seat belt and/or an appropriate child restraint system.
● To achieve a proper seating position, do not recline the seat more than
necessary. The seat belt is most effective when the occupants are sitting
up straight and well back in the seats.
● Do not wear the shoulder belt under your arm.
● Always wear your seat belt low and snug across your hips.
● Always wear the belt with the shoulder portion over the outside armrest
and the lap portion under the outside armrest.
If your seat belts cannot be fastened
securely because they are not long
enough, a personalized seat belt
extender is available from your Toyota
dealer free of charge.
