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 sub-
jected 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 airbags do not generally inflate if the vehicle is involved in a fron-
tal or rear collision, if it rolls over, or if it is involved in a low-speed side colli-
sion.
The SRS curtain shield airbags do not generally inflate if the vehicle is involved
in a rear collision, if it rolls over, or if it is involved in a low-speed side or low-
speed frontal collision.

“PASSENGER AIR BAG” indicator information
If any of the following problems occur, it is possible that there is a malfunction in
the system. Have the vehicle inspected by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
Neither “ON” nor “OFF” comes on.
The indicator light does not change when the airbag manual on-off switch is
switched to “ON” or “OFF”.
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 depend-
ing on the age and size of the child. Holding a child in your arms is not a sub-
stitute for a child restraint system. In an accident, the child can be crushed
against the windshield, or between you and the vehicle’s interior. This may
cause death or serious injury to the child in the event of a sudden stop, sudden
swerve or accident.
Lexus strongly urges the use of a proper child restraint system that conforms
to the size of the child, installed on the rear seat. According to accident statis-
tics, 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 4 )
In the event of an accident, the force of the rapid inflation of the front passen-
ger airbag can cause death or serious injury to the child.
A forward-facing child restraint system may be installed on the front passen-
ger 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 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, center 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 dangerous 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
Follow the directions given in the child restraint system installation manual and
fix the child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child or other
passengers may be seriously injured or even killed in the event of a sudden
braking, sudden swerving or an accident.
If the driver’s seat interferes with the
child restraint system and prevents it
from being attached correctly, attach the
child restraint system to the right-hand
rear seat (left-hand drive vehicles) or the
left-hand rear seat (right-hand drive vehi-
cles).
Adjust the front passenger seat so that it
does not interfere with the child restraint
system.
When installing a forward-facing child
restraint system on the front passenger
seat, move the seat as far back as possi-
ble.
Failure to do so may result in death or
serious injury if the airbags deploy
(inflate).
