It's possible that an automatic belt could keep you from
fully opening a door. That can happen if the door was
slammed shut very hard. Just close the door all the way,
then slowly open it. If that doesn't
fix
it, then your Buick
needs service.
We hope you'll always keep your automatic belt buckled.
However, you may need to unbuckle it in
an
emergency.
And you would need to unbuckle it to let someone get
into the center front seat position, if your vehicle has
one.
To unbuckle the automatic belt, just push the button on
the buckle.
