Observe the following precautions to reduce the risk of injury in the event of
sudden braking or an accident.
Failing to do so may cause death or severe injury.
nWearing a seat belt
lEnsure that all passengers wear a seat belt.
l Always wear a seat belt properly.
l 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.
l Toyota recommends that children be seated in the rear seat and always
use a seat belt and/or an appropriate child restraint system.
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.

nSeat belt damage and wear
lDo not attempt to install, remove, modify, disassemble or dispose of the

n When using the rear center seat belt
n Using a seat belt extender
lDo not wear the seat belt extender, if you can fasten the seat belt without
the extender.
l Do not use the seat belt extender when installing a child restraint system,
because the belt will not securely hold the child restraint system, increas-
ing the risk of death or serious injury in the event of a collision.
l The personalized extender may not be safe on another vehicle, when
used by another person, or at a different seating position other than the
one originally intended.
NOTICE
nWhen using a seat belt extender
When releasing the seat belt, press on the buckle release button on the
extender, not on the seat belt.
This helps prevent damage to the vehicle interior and the extender itself.
Do not use the rear center seat belt with
either buckle released. Fastening only
one of the buckles may result in death or
serious injury in case of sudden braking
or a collision.

SRS airbag precautions
lThe SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
l Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too small
to use a seat belt should be properly secured using a child restraint sys-
tem. Toyota strongly recommends that all infants and children be placed in
the rear seats of the vehicle and properly restrained. The rear seats are
the safest for infants and children. ( →P. 82)
lIf the seat belt extender has been con-
nected to the driver’s seat belt buckle
but the seat belt extender has not also
been fastened to the latch plate of the
driver’s seat belt, the SRS driver’s air-
bag system will judge that the driver is
wearing the seat belt even though the
seat belt has not been connected. In
this case, the driver’s airbag may not
activate correctly in a collision, resulting
in death or serious injury in the event of
collision. Be sure to wear the seat belt
with the seat belt extender.
