Have a look on the seat back low down beside the rear seat belt buckles and you will see a couple of labels on each side adjacent to a slot in the seat fabric showing where the isofix mounts are. Stick your finger through the gap and you'll feel the bar which the child seat latches onto. There is also a rear tether point available for each side. Open the tailgate and at the top LHS and RHS there is an access panel which hinges down to reveal the tether point. This is an optional fitting with some child seats, some use a stabilising leg as an alternative which simply rests on the rear floor.
