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.

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.
