Review your vehicle's owner manual for vehicle seat belt use
6. Route the Vehicle Seat Belt
Thread vehicle seat belt through
the forward-facing belt path
(marked with a orange label)
and out the other side. Buckle it.
The seat belt should lie as flat as
possible and not be twisted.
7. Tighten the Vehicle Seat Belt
In most vehicles today, slowly pull
the shoulder belt all the way out
and then let it go back in. You will
hear a clicking sound. Slowly pull
out on the belt and it should be
locked. If not, review your car's
owner manual and section 8-F.
