Securing a Child Restraint in the
Right Front Seat
To use a child restraint here, you will
need a special infant/child seat
attaching belt and the hardware that
goes with it. See the earlier section
about the top strap if the child restraint
has one.
Your dealer can get these and install the
hardware for you. It's free. The special
belt is GM Part Number 12340286.
Your dealer can find the correct
hardware in the accessory section of the
GM Parts Catalog.
