How should I affix the top tether?
The top tether is a belt with a metal snap hook at the back of the seat which can be lengthened or shortened depending on the anchor point where it is attached, either the base of the trunk or the back of the seat. It is therefore an anti-tipping system that acts as an anchor to attach the child seat to the chassis of the car.
However, not all ISOFIX seats have a top tether. They can also have a third point of support or lower leg that is not difficult to position. As a guide to make its positioning absolutely clear, we recommend you refer to the following infographic.
