Top Strap If your vehicle is not a convertible and you need to have an anchor installed, you can ask your Pontiac dealer to put one in for you. If you wantto install an anchor yourself, your dealer can tell you how to do it. Canadian law requires that child restraints have a top strap, and that the strap be anchored. If your child restraint has a top strap, your dealer can obtain a kt with anchor hardware and installation instructions specifically designed for this vehicle. The dealer can then install the anchor for you. In Canada, this work will be done for you free of charge. Or, you may install the anchor yourself using the instructions provided in the kit. If your child restraint has a top strap, it should be anchored. If you have a convertible, don't use a restraint like that in your vehicle because the tap strap anchor cannot be installed properly. You shouldn't use this type of restraint without anchoring the top strap.
