Can anyone tell me how to remove the front seat of a 96 peugeot 106?

There are 4 bolts holding the seat down (same on all 106s) situated at the front and rear of the slide rails. These require a Torx T40 driver.

Be sure to unplug the Seatbelt tensioner lead before lifting the seat up and don't drop the seat onto a hard surface or hit the seat belt buckle assembly with any object as the tensioner system (located in the seat belt buckle) has a small explosive charge in it.
