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.
To unbuckle the automatic belt, just push the
button on the buckle.
To reattach the automatic belt:
1. Close and lock the door.
2. Adjust the seat (to see how, see “Seats” in the Index)
so you can sit up straight.
3. Pick up the latch plate and pull the belt across you.
Don’t let it get twisted.
4. Push the latch plate into the buckle until it clicks.
