Removal of battery

[Alf Wood]

Hello ! I am in a right pickle. I need some advise on how to remove the battery from our 2007 Tigra. I have seen some 

video's but they feature the Corsa and is different in some small ways to the area around the Tigra battery. Nor sure what to pull out or undo ie, what to move to create enough space to lift out the battery. For instance on the Corsa is a centre screw which once removed allows the plastic surround to be lifted. This does not feature on the Tigra.

Some advise would be more than welcome,

Many thanks,

Alf Wood
