How do I install the car seat base using ISOFIX?

First, fit the ISOFIX guides with the ISOFIX anchor points on your vehicle seat. Place the base on the seat and pull the load leg downward to the floor. Press the ISOFIX adjuster button to extend the ISOFIX connectors until both show completely green indicators, confirming secure attachment. Make sure the load leg indicator also shows green before use. (Page 8-9)
