In Canada, the law requires that forward-facing child restraints have a top strap, and that the strap be anchored. In the United States, some child restraints also have a top strap. If your child restraint has a top strap, it should be anchored. If your vehicle is not a convertible, two top strap anchors are already installed for the rear seating positions. You'll find the anchors behind the rear seat, on the floor in the cargo area. If you have a convertible, don't use a child restraint with a top strap in your vehicle because the top strap anchor cannot be installed properly. You shouldn't use this type of restraint without anchoring the top strap. Anchor the top strap to one of these anchor points. Be sure to use an anchor point located on the same side of the vehicle as the seating position where the child restraint will be placed. If you have an adjustable head restraint, raise the head restraint and route the top strap under it. 1-39
