WARNING
■When a child is riding
Observe the following precautions.
Failure to do so may result in death or serious injury.
● For effective protection in automobile accidents and sudden stops, a child
must be properly restrained, using a seat belt or child restraint system
which is correctly installed. For inst allation details, refer to the operation
manual enclosed with the child restraint system. General installation
instructions are provided in this manual.
● Toyota strongly urges the use of a proper child restraint system that con-
forms to the weight and size of the child, installed on the rear seat. Accord-
ing to accident statistics, the child is safer when properly restrained in the
rear seat than in the front seat.
● Holding a child in your or someone else’s arms is not a substitute for a
child restraint system. In an accident, the child can be crushed against the
windshield or between the holder and the interior of the vehicle.
■ Handling the child restraint system
If the child restraint system is not properly fixed in place, the child or other
passengers may be seriously injured or even killed in the event of sudden
braking, sudden swerving, or an accident.
● If the vehicle were to receive a strong impact from an accident, etc., it is
possible that the child restraint system has damage that is not readily visi-
ble. In such cases, do not reuse the restraint system.
● Depending on the child restraint system, installation may be difficult or
impossible. In those cases, check whether the child restraint system is
suitable for installment in the vehicle ( P. 59). Be sure to install and
observe the usage rules after carefully reading the child restraint system
fixing method in this manual, as well as the operation manual enclosed
with the child restraint system.
● 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.

WARNING
■When using a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
● Never use a rear-facing child restraint
system on the front passenger seat
when the airbag manual on-off switch is
on. ( P. 51)
The force of the rapid inflation of the
front passenger airbag can cause death
or serious injury to children in the event
of an accident.
● There is a label(s) on the passenger
side sun visor, indicating it is forbidden
to attach a rear-facing child restraint
system to the front passenger seat.

*1: Move the front seat fully rearward. If the passenger seat height can be
adjusted, move it to the upper most position.
*2: Adjust the seatback angle to the
most upright position.
When installing a forward-facing
child seat, if there is a gap between
the child seat and the seatback,
adjust the seatback angle until
good contact is achieved.
*3: If the head restraint interferes with your child restraint system, and the
head restraint can be removed, remove the head restraint.
Otherwise, put the head restraint in the upper most position.
When securing some types of child restraint systems in rear seat, it
may not be possible to properly use the seat belts in positions next
to the child restraint without interfering with it or affecting seat belt
effectiveness. Be sure your seat belt fits snugly across your shoul-
der and low on your hips. If it does not, or if it interferes with the
child restraint, move to a different position.
Failure to do so may result in death or serious injury.

●When installing a child restraint in the rear seats, adjust the front
seat so that it does not interfere with the child or child restraint
system.
● When installing a child seat with support base, if the child seat
interferes with the seatback when latching it into the support
base, adjust the seatback rearward until there is no interference.
● If the seat belt shoulder
anchor is ahead of the child
seat belt guide, move the
seat cushion forward.
● When installing a junior seat, if the child in your child restraint
system is in a very upright position, adjust the seatback angle to
the most comfortable position. And if the seat belt shoulder
anchor is ahead of the child seat belt guide, move the seat cush-
ion forward.
