WARNING
■Child restraint precautions
● For effective protection in automobile accidents and sudden sto ps, a child
must be properly restrained, using a seat belt or child restrai nt 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 syste m 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” i ndicator light is illuminated.
In the event of an accident, the force of the rapid inflation o f the front pas-
senger airbag can cause death or serious injury to the child if the rear-fac-
ing 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.

WARNING
■Child restraint precautions
● Do not use the seat belt extender when installing a child restr aint system
on the front or rear passenger seat. If installing a child rest raint 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 dea th or seri-
ous injury to the child or other passengers in the event of 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 pillar s or roof side
rails from which the SRS side airbags or SRS curtain shield air bags 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 th e 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 properl y secured. If
it is not secured properly, it may cause death or serious injury to the child
in the event of a sudden stop 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 sh ould 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 ev en 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. This will prevent it from injuring passengers in the event of a sud-
den stop or an accident.
