How to Lower the Rear Seats of a Citroen C4 Grand Picasso

In this video, we see how to lower the seats of the Citroen C4 Grand Picasso: the first thing to do is remove the parcel shelf and lower the load floor. Pull down the red straps that allow you to lower the two rear seats, which we cover with the expandable load floor. Now, go to the second row and take the black strap to push the first seat forward and fold it onto itself. At the back of this, there is a panel continuing from the load area. Do the same with the centre seat and then move to the other side to complete the operation with the last seat. The reverse operation is very simple to put all the seats back in place.
