Top Strap Canadian law requires that forward - facing child
restraints have a top strap, and that the strap
be anchored.
If your child restraint has a top strap, it should be
anchored. If you need to have an anchor installed, your
dealer can obtain a kit with anchor hardware and
installation instructions specifically designed for this
vehicle. The dealer can then install the anchor for you.
This work will be done for you free of charge. Or, you
may install the anchor yourself using the instructions
provided in the kit.
