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.

Safety information for children
It is recommended that children sit in the rear seats to avoid acci-
dental contact with the shift lever, wiper switch etc.
Use the rear door child-protector lock or the window lock switch
to avoid children opening the door while driving or operating the
power window accidentally. (P. 184, 215)
Do not let small children operate equipment which may catch or
pinch body parts, such as the power window, hood, trunk, seats
etc.
Observe the following precautions when children are in the vehi-
cle.
Use a child restraint system appropriate for the child, until the
child becomes large enough to properly wear the vehicle’s seat
belt.
CAUTION
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the windows, the moon roof or other features of the vehicle. In addition,
heat build-up or extremely cold temperatures inside the vehicle can be fatal
to children.

Child restraint systems
Studies have shown that installing a child restraint on a rear seat is
much safer than installing one on the front passenger seat.
Choose a child restraint system that suits your vehicle and is
appropriate to the age and size of the child.
For installation details, follow the instructions provided with the
child restraint system.
General installation instructions are provided in this manual.
(P. 71)
If child restraint system regulations exist in the country where
you reside, please contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional for
the child restraint system installation.
Lexus recommends that you use a child restraint system which
conforms to the regulation ECE No.44.
Lexus strongly urges the use of child restraint systems.
