I put mine on the lowest setting when I first bought it, I think these are the steps you need to take:
1. take the keys out, and go and put them in the house (unlike me) if you put your ignition on when the seat is out of the car you will need to have your airbag light reset (like me).
2. Remove connector block from under the seat (not sure if you have to do step 3 first) but be aware of it.
3. There are 4 bolts holding the seat in place - undo these
4. remove seat and subframe from car (carefully)
(you can now see the 4 bolts you need to get at to adjust height/position, but trim is in the way)
5. remove tilter knob from side of seat using an allen key.
6. remove plastic side piece from seat using a hex bolt socket.
7. undo 4 positioning bolts and refit in right position.
8. put seat back into the car (carefully)
9. reconnect connector plug.
10. refit 4 bolts holding subframe in place
11. go back in house and get your keys, hopefully cup of tea waiting
job's a good un
