The lower tether anchorage points can mainly be used in combination with the car's seatbelt to secure certain rearward-facing child restraints.
Child restraints installed on any second row seat can use these anchorage points.
The lower tether anchorage points can be found at the back of the floor rails of the front seats.
Note
Manufacturer's instructions
When using anchorage points, always follow the instructions from the manufacturer of the child restraint.
