For cars with folding head restraints on the outside seats, the head restraints should be folded to facilitate installation.
The upper mounting points are primarily intended for use with front-facing child seats. Volvo recommends that small children should sit in rear-facing child seats for as long as possible.
For detailed information on how the child seat should be tensioned in the upper mounting points, see the seat manufacturer's instructions.
The child seat's straps must always be drawn through the hole in the head restraint leg before they are tensioned at the attachment point.
