Use of the child seat on the front
passenger seat 2) Transporting children on the front passenger
seat is not permitt

e, not all child seats are approved for use
on the front passenger seat. Your SEAT deal-

child seats. Only used child seats that are
approved for each vehicle.
The front airbag on the front passenger side
is highly dangerous for a child. The front pas-
senger seat is life-threatening to a child if he
