Types of collisions that may not deploy the SRS airbags (SRS side and curtain
shield airbags)
The SRS side and curtain shield airbags may not activate if the vehicle is
subjected to a collision from the side at certain angles, or a collision to the
side of the vehicle body other than the passenger compartment.
The SRS side and curtain shield airbags do not generally inflate if the vehicle
is involved in a frontal or rear collision, if it rolls over, or if it is involved in a
low-speed side collision.

CAUTION
When installing a child restraint system
For safety reasons, always install a child restraint system in a rear seat. In
the event that the rear seat cannot be used, the front seat can be used as long
as the airbag manual on-off system is set to off.
If the airbag manual on-off system is left on, the strong impact of the airbag
deployment (inflation) may cause serious injury or even death.
When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off system is set to on.
If it is left off, the airbag may not deploy in the event of an accident, which
may result in serious injury or even death.

CAUTION
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.
Lexus 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 use a rear-facing child restraint system on the front passenger seat
when the airbag manual on-off switch is on. (P. 5 6 )
In the event of an accident, the force of the rapid inflation of the front pas-
senger airbag can cause death or serious injury to the child.
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 strap should not be used in the front passenger seat since
there is no top strap anchor for the front passenger seat. Adjust the seat-
back as upright as possible and always move the seat as far back as possi-
ble 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 and rear pillars or roof side
rails from which the SRS side airbags or SRS curtain shield airbags
deploy even if the child is seated in the child restraint system. It is danger-
ous if the SRS side airbags and curtain shield airbags inflate, and the
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 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, sudden swerve or accident.

CAUTION
When installing a child restraint system
Never use a rear-facing child restraint
system on the front passenger seat
when the airbag manual on-off switch

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 sys-
tem to the front passenger seat.
