Top Strap
If your child restraint has a top strap, it should be
anchored. If you have a two-door model, don't use a
restraint like that 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.
If your vehicle is
a four-door model and you need to
have an anchor installed,
you can ask
your dealer to put
one in for you. If you want to install an anchor yourself,
your dealer can tell you how to do it. Use the tether
hardware kit available from the dealer. The hardware
and installation instructions were specifically designed
for this vehicle.
