Newbie, needing some fuse box info

I have recently purchase a Vauxhall  Zafira, 2004 diesel, that I absolutely love!

And luckily the only problem that I am having is that the lighter doesn't work.

Im not a smoker, so when I bought the car, this didn't bother me, but I am enjoying driving it so much that I am now driving it all over the place and I need the lighter now to charge a sat nav.

I know that the fuse box is by the steering wheel, but I have no idea what number it is for the lighter.

Any help would be much appreciated!

 

Many thanks!
