There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a
smaller adult sits in the front pa ssenger seat, the system may rec-
ognize him/her as a child depending on his/her physique and pos-
ture.
*2: In the event the front passenge r does not wear a seat belt.
*3: When a large child who has outgrown a child restraint system sits
in the front passenger seat, the system may recognize him/her as
an adult depending on his/her physique or posture.
*4: Never install a rear-facing child restraint system on the front pas- senger seat. A forward-facing chil d restraint system should only
be installed on the front passenger seat when it is unavoidable.
(  P. 132)
*5: In case the indicator is not illumin ated, consult this manual as for
installing the child restraint system properly. ( P. 137)

Child restraint systems
Points to rememberStudies have shown that installing a child restraint system on a rear
seat is much safer than installing one to the front passenger seat.
● Choose a child restraint system th at suits your vehicle and is
appropriate to the age and size of the child.
● For installation details, follow the instructions provided with the
child restraint system. 
General installation instructions are provided in this manual. 
(  P. 137)
Types of child restraints
Child restraint systems are classi fied into the following 3 types
according to the age and size of the child.
Rear facing  Infant seat/convertible seat
A child restraint system for a small ch ild or baby must itself be prop-
erly restrained on the seat with th e lap portion of the lap/shoulder
belt.
The laws of all 50 states of the U.S.A. and Canada now require the
use of child restraint systems.

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 “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 “AIR BAG OFF” indicator light is illuminated,
because the front passenger airbag could inflate with considerable speed
and force. Failing to do so may cause death or serious injury to the child.
● 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 accident.
