CAUTION
Observe the following precautions to reduce the risk of injury in the event of
emergency braking, sudden swerving 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.
l Do not recline the seat any more than necessary to achieve a proper seat-
ing position. The seat belt is most effective when the occupants are sitting
up straight and well back in the seats.
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.

CAUTION
nChild restraint lock function belt precaution
Do not allow children to play with the child restraint lock function belt. If the
belt becomes twisted around a child’s neck, it will not be possible to pull the
belt out leading 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.
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 an accident.
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.
