WARNING
■When installing a child restraint system
For safety reasons, always install a child rest raint 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

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.
