Passenger airbag OFF
To assure the safety of your child, you must deactivate the passenger's front airbag when
you install a child seat in the rearwards facing position on the front passenger's seat.
Otherwise, there is a risk that the child could be seriously injured or killed if the airbag were
deployed.
Refer to the advice given on the label present
on both sides of the passenger's sun visor.
