WARNING
■Child restraint precautions
●For effective protection in automobile accidents and sudden stops, a child
must be properly restrained, using a seat belt or child restraint system
depending on the age and size of the child. Holding a child in your arms is
not a substitute for a child restraint system. In an accident, the child can be
crushed against the windshield, or between you and the vehicle’s interior.
● Toyota strongly urges the use of a proper child restraint system that con-
forms to the size of the child, installed on the rear seat. According to acci-
dent statistics, the child is safer when properly restrained in the rear seat
than in the front seat.
● Never install a rear-facing child restraint system on the front passenger
seat even if the “AIR BAG OFF” indicator light is illuminated. In the event
of an accident, the force of the rapid inflation of the front passenger airbag
can cause death or serious injury to the child if the rear-facing child
restraint system is installed on the front passenger seat.
● A forward-facing child restraint system may be installed on the front pas-
senger seat only when it is unavoidable. A child restraint system that
requires a top tether strap should not be used in the front passenger seat
since there is no top tether strap anchor for the front passenger seat.
Adjust the seatback as upright as possible and always move the seat as
far back as possible even if the “AIR BAG OFF” indicator light is illumi-
nated, because the front passenger airbag could inflate with considerable
speed and force. Otherwise, the child may be killed or seriously injured.
● 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.

WARNING
■Child restraint precautions
●Do not allow the child to lean his/her head or any part of his/her body
against the side door or the area of the seat, front and side pillars or roof
side rail from which the SRS side airbags or curtain shield airbags deploy
even if the child is seated in the child restraint system. It is dangerous if
the SRS side airbags and 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.
■ 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.
■ When the child restraint 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 passenger com-
partment.
● 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
an accident.
