Hi,
There are two Allen key bots at the back of the seat base. To access these you fold the seat down where you will see about 5 buttons which you need to undo. You then push the fabric under the seat back to reveal the bolts. You then undo the bolts and slide the seat base forward under the seat belt mounts.
The battery should be behind the driver..
The above is for a 2007 4 seater but it should be the same for a 2010 one.
Sorry it's not the easiest to explain but hopefully the above will help.
Out of interest, do you find the car bottoms out over bumps with passengers in the back seats?
Thanks
Will
