Your car's various anchorage points can be used in combination with each other or along with other fastening methods to secure different types of child restraints.
ISOFIX, also known as LATCH or LUAS, is an international standard for child restraint anchorage points that can be used in combination with the top tether anchorage points or a support leg.
Some child restraints are secured using a car seatbelt, usually in combination with other fastening methods.
Note
Manufacturer's instructions
When using anchorage points, always follow the instructions from the manufacturer of the child restraint.
