CHILD RESTRAINT
Child restraint precautions
Lexus strongly urges the use of appropriate child
restraint systems for children.
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 ªSeat beltsº on page 110 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 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.
 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 install a rear±facing child restraint system on
the front passenger seat. 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 should be
allowed to be installed on the front passenger seat
only when it is unavoidable. Always move the seat as
far back as possible, because the front passenger
airbag could inflate with considerable speed and
force. Otherwise, the child may be killed or seriously
injured.
 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 or side pillar or roof side rail from which
the side airbags or curtain shield airbags deploy even
if the child is seated in the child restraint system. It is
dangerous if the side airbags and curtain shield
airbags inflate, and the impact could 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 serious injury to the child
or other passengers in the event of collision. 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 or accident.

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 child restraint
system.
Install the child restraint system correctly following the
instructions provided by its manufacturer. 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.
When not using the child restraint system, keep it secured with
the seat belt or place it in the trunk or somewhere other than
the passenger compartment. This will prevent it from injuring
passengers in the event of a sudden stop or accident. Types of child restraint system
Child
restraint systems are classified into the following 3 types
depending on the child's age and size.
(A) Infant seat
(B) Convertible seat
(C) Booster seat
Install the child restraint system following the instructions
provided by its manufacturer.
Your vehicle has anchor brackets for securing the top strap of
a child restraint system.
For instructions about how to use the anchor bracket, see
ªUsing a top strapº on page 156, 161 or 167.
The child restraint lower anchorages approved for your vehicle
may also be used. See ªInstallation with child restraint lower
anchoragesº on page 159 or 174.
