Just noticed one of the seat belt locks is "missing" on the back seat.  Chances are it has fallen underneath - but it is tricky moving the bum cushion.  What is the best way to get under the seat?

In front of the rear seat cushion you will see a tapper hanging down.

Pull it towards the front seat to release the seat from its locking unit and the front of the seat cushion will lift upwards.

This will allow you to push the front of the seat cushion up and pull it forward towards the front seat.
