The iPro Base can be used in vehicles equipped with an ISOFIX connection or with i-Size vehicle seats. For this purpose, the individually adjustable ISOFIX connectors are clicked into the ISOFIX hooks of the car. When the safety indicator turns green, the base is correctly secured. The stand leg is height-adjustable and is released using a one-handed mechanism. Once placed on the vehicle floor, it automatically locks into position. The green indicator also shows the correct position here. The same applies to the installation of child seats on the iPro Base. Both the iPro Baby and iPro Kids are simply placed in the center of the base using the Easy-Slide function. Special guiding rails ensure that the car seats always slide correctly into the base and lock in place. Color indicators show the correct installation and locking status. To unlock the infant carrier from the base, the button located in the center on the front side of the base is pressed.
