If your child restraint is equipped with the LATCH system, see Lower Anchors and Tethers for Children (LATCH) in the Index. See Top Strap if the child restraint has one.
There is no top strap anchor at the third row driver side position. Do not secure a child seat in this position if a national or local law requires that the top strap be anchored, or if the instructions that came with the child restraint say that the top strap must be anchored.
If your child restraint does not have the LATCH system, you will be using the lap-shoulder belt to secure the child restraint in this position. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say.
To remove the child restraint, just unbuckle the vehicle's safety belt and let it go back all the way. The safety belt will move freely again and be ready to work for an adult or larger child passenger.
