Toyota Assessment of SAB Systems

• From the beginning of Toyotas SAB development,
  systems were assessed by stringent internal
  standards.
• These internal standards included assessment of
  OOP risk to children.
• Since the OOP voluntary procedures were published
  (August 2000), all Toyota systems are designed
  according to these procedures.
