CHILD RESTRAINT
Child restraint precautions
Lexus strongly urges the use of child restraint systems for
children small enough to use them.
The laws of all 50 states in the U.S.A. and Canada now require
the use of a child restraint system.
Your vehicle conforms to SAE J1819.
If a child is too large for a child restraint system, the child should
sit in the rear seat and must be restrained using the vehicle's
seat belt. See ºSeat beltsº on page 113 for details.
CAUTION
 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 age and size. 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
if you are unrestrained.
 Lexus strongly urges use of a proper child restraint
system which conforms to the size of the child,
installed on the rear seat. According to accident
statistics, the child is safer when properly restrained
in the rear seat than in the front seat.
 Never put a rear±facing child restraint system on the
front seat. In the event of an accident, the force of the
rapid inflation of the airbag can cause death or
serious injury if a rear±facing child restraint system
is put on the front seat.
 Unless it is unavoidable, do not put a forward±facing
child restraint system on the front seat.
 A forward±facing child restraint system should be
allowed to be put on the front passenger seat only
when it is unavoidable. Always move the seat as far
back as possible, because the force of the deploying
front passenger airbag 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. On vehicles with side airbags and curtain
shield airbags, do not allow the child to lean over the
front door or around the front door even if the child
is seated in a child restraint system. It is dangerous
if the side and curtain shield airbags inflate, and the
impact could cause death or serious injury to the
child.

Child restraint system
A child restraint system for a small child or baby must
itself be properly restrained on the seat with the lap
portion of the lap/shoulder belt. You must carefully
consult the manufacturer's instructions which
accompany the child restraint system.
To provide proper restraint, use a child restraint system
following the manufacturer's instructions about the
appropriate age and size of the child for the restraint system.
Install the child restraint system correctly following the
instructions provided by its manufacturer of the system.
General directions are also provided under the following
illustrations.
The child restraint system should be installed on the rear seat.
According to accident statistics, the child is safer when
properly restrained in the rear seat than in the front seat.CAUTION
Never put a rear±facing child restraint system on the
front seat. In the event of an accident, the force of the
rapid inflation of the airbag can cause death or
serious injury if a rear±facing child restraint system
is put on the front seat.
 Unless it is unavoidable, do not put a forward±facing
child restraint system on the front seat.
 A forward±facing child restraint system should be
allowed to be put on the front passenger seat only
when it is unavoidable. Always move the seat as far
back as possible, because the force of a deploying
front passenger airbag could cause death or serious
injury to the child.
 On vehicles with side airbags and curtain shield
airbags, do not allow the child to lean over the front
door or around the front door even if the child is
seated in a child restraint system. It is dangerous if
the side and curtain shield airbags inflate, and the
impact could cause death or serious injury to the
child.
 After installing the child restraint system, make sure
it is secured in place according to the manufacturer's
instructions. If it is not restrained securely, it may
cause death or serious injury to the child in the event
of a sudden stop or accident.

not using the child restraint system, keep it secured with
the seat belt or place it in the trunk or somewhere other than
in the passenger compartment. This will prevent it from

a child restraint system.

child and front passenger in case of sudden braking
or a collision.
