■Types of collisions that may not deploy the SRS airbags (SRS side and curtain shield air-
bags)
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 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.
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 sys-
tem. Have the vehicle inspected by any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.

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 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. 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 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 2 )
In the event of an accident, the force of the rapid inflation of the front passenger air-
bag can cause death or serious injury to the child.
●A forward-facing child restraint system may be installed on the front passenger 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 air-
bags 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 swerv-
ing 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 vehicles).
●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 possible.
Failure to do so may result in death or serious
injury if the airbags deploy (inflate).
