SRS airbag precautions
● The 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.
● 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
safer for infants and children than the front passenger seat. ( P. 136)
●If 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 airbag
system will judge that the driver is
wearing the seat belt even though the
seat belt has not been connected. In
this case, the SRS driver airbag may
not activate correctly in a collision,
resulting in death or serious injury in the
event of a collision. Be sure to wear the
seat belt with the seat belt extender.

CAUTION
■
Child restraint precautions
● Do not use the seat belt extender when installing a child restraint system
on the front or rear passenger seat. If installing a child restraint system
with the seat belt extender connected to the seat belt, the seat belt will not
securely hold the child restraint system, which could cause death or seri-
ous injury to the child or other passengers in the event of a sudden stop,
sudden swerve or an accident.
● Do not allow the child to lean his/her head or any part of his/her body
against the door or the area of the seat , front and rear pillars or roof side
rail from which the SRS side airbags or SRS curtain shield airbags deploy
even if the child is seated in the child restraint system. It is dangerous if
the SRS side airbags and SRS curtain shield airbags inflate, and the
impact could cause death or serious injury to the child.
● Make sure you have complied with all installation instructions provided by
the child restraint manufacturer and that the system is properly secured. If
it is not secured properly, it may cause death or serious injury to the child
in the event of a sudden stop, sudden swerve or an accident.
■ Child 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.
■ When the child restrain t system is not in use
● Keep the child restraint system properly secured on the seat even if it is
not in use. Do not store the child restraint system unsecured in the pas-
senger compartment.
● If it is necessary to detach the child restraint system, remove it from the
vehicle or store it securely in the luggage compartment. This will prevent it
from injuring passengers in the event of a sudden stop, sudden swerve or
accident.
