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 restr aint
system.
General installation instructions are provided in this manual. ( P. 66)
● If child restraint system regulations exist in the country where you reside,
please contact any authorized Lexus reta iler or Lexus authorized repairer, or
any reliable repairer 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.
